Long-term sustainable port development requires accounting for the intrinsic values of ecosystems. However, in practice, ecosystem considerations often only enter the planning and design process of ports when required by an Environmental Impact Assessment. At this late stage, most of the design is already fixed and opportunities to minimize and restore ecosystem impacts are limited. In this paper, we adopt a large-scale, ecosystem perspective on port development with the aim to identify ecosystem-based design alternatives earlier and throughout the planning and design of a port’s marine infrastructure. We present a framework, termed the ‘ecosystem-based port design hierarchy’ (EPDH), to identify ecosystem-based alternatives at four hierarchical design levels: 1) alternatives to port developments, 2) port site selection, 3) port layout design, and 4) design of structures and materials. In applying the EPDH framework retrospectively to a case study of port expansion in Tema, Ghana, we establish that ecosystem considerations played only a limited role in identifying and evaluating alternatives at all four design levels in the case study, whereas more eco-friendly alternatives in terms of port layouts, structures, and materials are identified using the EPDH framework. This reveals that opportunities for ecosystem-friendly port designs may have been missed and demonstrates the need for and the potential added value of our framework. The framework can assist practitioners in earlier and wider identification of ecosystem-based alternatives for a port’s marine infrastructure in future seaport developments and, hence, represents an important step towards more sustainable port designs.

Abstract Under the new normal of China’s economy, the competition among the port enterprises is not only the competition of the core competence of the port, the port industry chain or the port supply chain, but also the competition of the port service ecosystem. In this paper, the concept and characteristics of the port service ecosystem is discussed, a hierarchical model of the port service ecosystem is constructed. As an extended logistic model, Lotka-Volterra model is applied to study the competitive co-evolution and mutually beneficial co-evolution of enterprises in the port service ecosystem. This paper simulates the co-evolution of enterprises in the port service ecosystem by using MATLAB programming. The simulation results show that the breadth of the niche of the enterprises is changing with the change of the competition coefficient and the coefficient of mutual benefit in the port service ecosystem. Based on that, some proposals are put forward to ensure the healthy and orderly development of the port service ecosystem.

Ecosystem services of the marine environment can be considered as ecological, economic and social components of sustainable development, but at present, they are not fully evaluated. In this regard, the article sets the task of identifying and valuing ecosystem services in port waters. As a result of the study, the attribution of the benefits created by the port waters to the ecosystem services of the marine environment is justified, their division into two categories is carried out—into providing and supporting services, a methodology for their cost estimation is proposed. It is proposed to calculate ecosystem services by the amount of port water rent, which is understood as the residual income in port activities after deducting from it all costs and profit margins on fixed assets of port infrastructure. According to this methodology, calculations of the total cost of ecosystem services of port water areas for Russia as a whole and specific values of the cost of ecosystem services per 1 km² of port water area for all seaports of the country were carried out. Supporting services are proposed to be assessed by the rent of assimilation potential formed when compensatory measures are not carried out for environmental damage caused by port activity. According to the results of calculations, it was revealed that the total port rent is approximately 33–38 billion rubles. At the same time, payments for the use of water resources in the waters of seaports entering the budget system amount to an insignificant part of this value—0.17 %, which indicates the inefficiency of the current payment system. To correct the situation, an algorithm for calculating fees for ecosystem services in port waters with the inclusion of an environmental component is proposed, the maximum share of port water rent (10 %) is justified, without disturbing the balance between the state and private structures. The significance of the work carried out is to substantiate a new category of ecosystem services of the marine environment, ecosystem services of port waters, and to show the possibility of using their valuation for management purposes, including through the formation of additional budget revenues.

There is a gradual but clear transition towards a circular economy (CE) that will potentially have significant impacts on ports, both in their function as transport nodes and as locations for logistics and manufacturing activities. A rough appraisal of new investments in circular manufacturing activities in ports in Europe drawn from organizational reports and official webpages illustrates the (slow) development of circular activities in ports. This paper is to our knowledge the first paper which deals with the implications of CE for the business model of the port development company. We assess if and how the circularity transition affects the role and business model of port authorities as developers of port clusters. We outline a framework for analyzing the consequences of CE on the business model of the port authority. We then apply this framework to get a detailed understanding of the emerging CE ecosystem in the Port of Amsterdam, which is clearly a frontrunner in the transition, and the role of the government-owned Port of Amsterdam port development company (PoA) in developing this ecosystem. In Amsterdam, a CE ‘business ecosystem’ has emerged and continues to evolve with three types of synergies between the companies in this ecosystem: logistics infrastructure and services synergies, input–output synergies and industrial ecology synergies. We find that the spatial scale of the CE value chains in the port varies between segments and that they are generally less international than ‘linear’ value chains. The development of CE activities occupies a central place in PoA’s strategy, and PoA assumes new and active roles in advancing the circular business ecosystem, most notably through developing industrial ecology synergies and nurturing and attracting new, innovative CE companies. Finally, the circularity transition leads to changes in PoA’s business model, with an increasing focus on new services that create synergies, and a decreasing importance of the share of port dues in the total revenue mix.

This research examines the issue of why Co-Fish Project is important for the ecosystem in the Tegal Port area and how the project was implemented during 1998-2005 and the impacts of the project on fishing communities. It is used as a historical method with the ecosystem approach because Co-Fish Project intended to maintain, improve, and develop the benefit value and the ecosystem function for the progress of all elements or stakeholders in the ecosystem. The research results show that Co-Fish Project in Tegal City is an integral part of the Coastal Fishing Port (PPP) construction project and the development of the Tegalsari Fish Landing Base (PPI) of Tegal City. Co-Fish Project as a central government project under the coordination and management of the Indonesian Ministry of Maritime Affairs and Fisheries with ADB funding sources requires the development and empowerment of the port area ecosystem as an instrument to support the development and sustainability of port activities. It is important because the condition of the existing slum port area is not organized with the socio-economic life of fishermen with high poverty levels and prone to conflicts among the fishermen. The implementation of the Co-Fish Project has a positive impact on reducing poverty and fishermen conflicts due to improvements in infrastructure, sanitation, and the development of fishermen's socio-economic institutions and the port area ecosystem synergizing with the increasing fishermen's income and social harmony.

Исследование, проведенное на основе теоретико-методологического подхода с позиции потенциального потребителя, связано с постановкой вопроса о предпосылках и перспективах формирования цифровой экосистемы непрерывных образовательных тренингов. Данная экосистема, позволяющая совместить интересы рынка труда и профессионального образования, предполагает создание сети образовательно-профессиональных площадок (онлайн-хабов) с использованием традиционных и платформенных цифровых носителей, объединенных в «гибридную» инфраструктуру, а также с учетом новых экономических реалий. Непрерывные профессионально-образовательные тренинги затрагивают интересы в первую очередь лиц трудоспособного возраста и нацелены на сохранение трудовой занятости и снижение рисков безработицы на региональном уровне. Существующий разрыв между низкой производительностью труда и опережающей индексацией бюджетных доходов, невысокими доходами молодых работников и неконкурентоспособными программами дополнительного профессионального образования может быть компенсирован с помощью цифровой экосистемы непрерывных профессионально-образовательных тренингов, направленных на формирование опережающих компетенций. Они смогут привлечь на рынок труда молодых трудоспособных лиц как основных производителей валового регионального продукта. Положения и выводы статьи основаны на зарубежном передовом опыте и отечественных образовательных стратегиях по созданию модели новой образовательной экосистемы. This research is made with a theoretical-methodological approach from the perspective of the consumer. It is related to the question of the prerequisites and prospects for the digital ecosystem of continuous educational training formation. The new educational ecosystem brings together the interests of the labour market and professional education using a network of educational and professional platforms (online hubs), which is built upon a “hybrid” infrastructure of traditional and platform digital media, taking into account the new economic realities. The continuous vocational trainings focus on persons of working age, young people, and are aimed at maintaining employment and reducing the risks of unemployment at the regional level. The establishment of a digital ecosystem of continuous vocational training to form outpacing competences can compensate for the gap between low labour productivity and outpacing budget income indexation, low staff rotation, low incomes of young workers and lack of competitive additional vocational training programmes. This could introduce young employable persons to the labour market as the main producers of common (regional) income. The ideas and conclusions are based on international advanced practices and national educational strategies of designing a model of a new educational ecosystem.

This research shows how port authorities in a triple helix context can contribute to strategic innovation with reduction of Levelized Cost of Energy in nearshore wind park ecosystems. The empirical qualitative case study was conducted from September 2017 to June 2018 with a port and a nearshore wind park owner and a logistic business actor operating on land and one operating at sea. Individual interviews and three joint network meetings provided data for the research. The findings reveal that port authorities in triple helix contexts can contribute to strategic innovation through use of the cross-disciplinary trinity of ‘organization’, ‘business model innovation’ and ‘financial cash flow’ to address value creation on project ecosystem level. The findings are summarized in a model for overview on the shift in interest and the basic understanding of flow. It is shown that the triple helix discussions provide a meaningful frame to achieve strategic innovation for competitive advantage of renewable wind energy ecosystem.Keywordsstrategic innovation – ecosystems – renewable energy – offshore wind parks

There is a growing interest in the application of ecological models to evaluate past, present, and future direct and indirect effects from various stressors including nutrients, organic wastes, flow, temperature etc. in aquatic ecosystems. For this study, AQUATOX simulation was established, calibrated and validated to model the aquatic ecosystem of Yincun Port River with field measured data and historical records between April 2013 and October2014. The results showed the AQUATOX simulation reasonably represented the real situation of Yincun Port. Moreover, sensitivity analysis revealed the value of Phytoplankton Chlorophyll was highly sensitive to nutrient input, temperature and parameters related to temperature limitations. Furthermore, this model was applied as a forecasting tool to analyze the response of Chl. a to nutrient input.

Анотація:
Mangrove communities are unique environments that line coastlines in tropical and subtropical latitudes. In Florida, four mangrove tree species dominate these communities and are accompanied by other primary producers, infaunal, epifaunal, and juvenile faunal species that together form the base of a complex, chiefly detritus-based food web. In an effort to evaluate mangrove communities in Port Everglades, Florida, tissue samples were taken from a diversity of mangrove- associated producer and consumer species from three mangrove sites. Stable carbon and nitrogen isotope ratios were used to establish patterns of energy flow of mangrove material, examine the influence of detrital material, and identify isotopic differences among mangrove species. R.mangle was the most depleted in δ13C, -34.11 to -26.19‰, while C.erectus was the most enriched, -29.91 to -25.30‰. This pattern mirrors the documented pattern of proximity to the waterline, but this pattern was not the same in δ15N, as C.erectus exhibited the narrowest range of δ15N values, -1.95 to 5.40‰. Significant differences were found in δ15N and δ13C signatures of the mangrove species among the tissue types, sampling sites, and trophic linkages among three sample sites, which could indicate differences between natural and anthropogenic influences, such as increased nitrate from a nearby residential area. Specifically, site 1, the only site located directly on the Intracoastal Waterway, differed significantly from sites 2 and 3, both of which were indirectly connected to the waterway. Results also established unique trophic levels, with primary producers at the bottom and carnivorous fish at the top. Slight differences among the trophic dynamics, such as a shift in diet specifically with fish species, among the sites revealed a possible influence of restricted tidal flow from mangrove communities.

A high-resolution pollen record from Path Lake (43°87’00”N, 64°92’42”W, 10m asl) in Port Joli Harbour, Nova Scotia, Canada, was used to provide a paleo-ecological perspective on Holocene climate and vegetation variability within the context of local archaeological research. Pollen assemblages in the early Holocene reflect a post-glacial forest dominated by Pinus, Tsuga, Betula and Quercus. Shallow water aquatic and wetland taxa increased after 3400 cal. yr. BP in response to wetter climatic conditions. Increased settlement intensity of native inhabitants coincides with late-Holocene climate change at a regional scale, suggesting that environmental conditions may have influenced prehistoric human activities. European settlement, after 350 cal. yr. BP, was marked by a rise in Ambrosia, and peak charcoal accumulation rates after this time showed evidence of human disturbance on the landscape. This study suggests that environmental changes affected human exploitation of the landscape, and human activity altered forest composition in the late Holocene.

The importance of ecological systems in supporting social systems has been identified as one of the most important facets of sustainable development. Consequently, a number of international and local laws and policy interventions have been established to ensure that natural resource use remains sustainable. In rural areas, overdependence on fuel wood has commonly been identified as one of the biggest threat to forestry ecosystems. This in turn has led to environmental degradation that includes among others species depletion, soil erosion and decline in water and air quality. Based on the myriad problems caused by over-reliance on fuel wood, this study sought to identify usage, management and perceived implication of woodland exploitation in Port St Johns local municipality in the Eastern Cape, South Africa. Using interviews and questionnaires for key respondents in the local community, the study identified two key threats to socio-ecological stability resulting from wood fuel exploitation namely; high poverty levels and lack of coordination in the management of wood fuel resources. Apart from using fuel wood for domestic use, local fuel wood exploitation has been commercialized to augment household incomes. Lack of coordination in the management of natural resources has also created a vacuum in the exploitation and management of fuel wood resources. The study did not have inclination towards statistics such as chi-square and t-tests since the research questions and objectives did not refer to any relationship or significance level. The study recommends non-wood based alternative sources of energy, improved coordination and harmonization of functions among different stakeholders and emphasis on collaboration between traditional and local governance in the management fuel wood and the local physical environment. The study further recommends resuscitation of indigenous knowledge and socio-ecological stability

L’hyper-anthropisation, en particulier le long de nos côtes, a profondément modifié l’environnement. De plus en plus de structures, telles que les ports, forment des écosystèmes à part entière. Parmi la multitude d’espèces qui peuplent le port, un groupe semble particulièrement intéressant à étudier : les Filtreurs (bivalve set tuniciers). Ces organismes, par leurs modes de vie, ont une forte interaction avec l’environnement portuaire. En effet, en restant fixés sur les structures, ils subissent sans cesse les facteurs environnementaux qui caractérisent le port et leur mode d’alimentation, la filtration, les amène à être en contact avec une grande quantité d’eau et donc avec les éléments qui s’y trouvent. L’objectif de ce travail de thèse est d’étudier ce socio écosystème particulier qu’est l’environnement portuaire à travers ce groupe clé : les filtreurs. Ce travail par une approche pluridisciplinaire a permis :-d’étudier et de cartographier les communautés de filtreurs présents dans le port de plaisance de La Rochelle ; montrant ainsi la complexité de leur communauté et le fait qu’elles seraient impactées par des facteurs anthropiques et hydrosédimentaires .-d’analyser l’effet de deux contaminants très présents en milieu portuaire, le cuivre et le zinc, sur un organisme filtreur modèle : le pétoncle (Mimachlamys varia) ; et de montrer leur impact sur plusieurs voies métaboliques impliquées dans de nombreuses fonctions biologiques, telles que l'osmorégulation, le stress oxydatif, métabolisme énergétique, la reproduction et des phénomènes d’apoptose.- de mettre en évidence le fait que les filtreurs interviennent dans la composition des vases en remobilisant les sédiments présents dans la colonne d’eau et en modifiant leurs propriétés physico-chimiques ;que cela est espèce-dépendant et fortement modulé par les conditions environnementales telles que le taux de matière organique.-de développer plusieurs méthodes d’échantillonnage et d’analyse novatrice nécessaires pour appréhender cet environnement particulierThe hyper-anthropization, particularly along our coasts, has profoundly modified the environment. New structures, such as harbors, emerging, forming “true” ecosystems. Among the multitude of species inhabiting the port, one group seems particularly interesting to study: the filter feeders (bivalves and tunicat). These organisms have a strong interaction with the port environment due to their behaviour. Indeed, by remaining anchored to the structures, they are constantly subjected to the environmental factors that characterize the port and their feeding behavior, the filtration, leads them to be in contact with a large quantity of water and therefore with the elements that are in it. The objective of this thesis is to study this particular socio-ecosystem that is the port environment through this key group: the filter feeders. Through a multidisciplinary approach, this work, has allowed :-to study and map the communities of filter feeders present in the marina of La Rochelle; showing the complexity of their community and the fact that they are impacted by anthropogenic and hydrosedimentary factors.-to analyze the effect of two common contaminants in the port environment, copper and zinc, on the metabolism of a model filter-feeder organism : the scallop (Mimachlamys varia); and to show that they impacted several metabolic pathways involved in numerous biological functions, such as osmoregulation, oxidative stress, energetic metabolism, reproduction and apoptosis.- to highlight the fact that filter feeders are involved in the composition of the mud by remobilizing the sediments present in the water column and by modifying their physico-chemical properties; and that is species dependent and is strongly modulated by environmental conditions such as the level of organic matter.- to develop several innovative sampling and analysis methods needed to understand this particular environment

Nous identifions ou isolons pour la premiere fois, onze souches 7-epimerisantes de l'ecosysteme intestinal de sujets sains. Elles appartiennent aux genres clostridium, eubacterium et ruminococcus. Nous identifions egalement plusieurs souches de cet ecosysteme, capables de realiser l'une ou l'autre des deux etapes de la 7-epimerisation de cdc en udc. En revanche, aucune des soixante-seize bacteries lactiques (souches d'interet agro-alimentaires) testees n'est active dans nos conditions experimentales. Une souche 7-epimerisante in vitro (clostridium absomum choisi comme modele) exprime egalement cette activite in vivo, lorsqu'elle transite vivante, dans l'intestin de porcs vigiles et normalement alimentes. Dans ces conditions, la reabsorption intestinale d'udc dans la veine porte est multipliee par un facteur 3,5 a 7,5. Il est donc possible d'augmenter udc dans l'intestin et la veine porte via l'administration de bacteries vivantes. L'enjeu suivant consistera a faire exprimer cette activite par des bacteries d'interet agro-alimentaire, afin de proposer de nouvelles souches probiotiques dans le cadre d'une nutrition preventive de pathologies majeures dont le developpement est ralenti voire supprime par udcWe identified or isolated for the first time, eleven 7-epimerising bacterial strains from the intestinal microbiota of healthy volunteers. These strains were members of the clostridium, eubacterium and ruminococcus genera. We also identified several strains carrying one of both enzymatic activities involved in the 7-epimerisation of cdc to udc. Conversely, none of the seventy-six lactic bacteria (safe food micro-organisms) was found to be active under our study conditions. One of the active strains (clostridium absonum) was taken as a model for assaying its activity in vivo, during its transit in the intestine of awaked and normally fed pigs. We demonstrated that udc absorbed into the portal vein, increased 3?5?7?5-fold, under administration of living compared to killed bacteria. It is therefore feasible to increase udca in the intestine and portal blood of conventional pigs treated with living 7-epimerising bacteria. This may represent a new interesting probiotic activity, useful for the prevention of major pathologies whose development is known to be slower or suppressed under udc-therapy, provided that in the future, the 7-epimerising activity could be expressed by a safe food micro-organism

Doutoramento em Engenharia Florestal e dos Recursos Naturais - Instituto Superior de AgronomiaForests are a key element in the Portuguese landscape. Moreover, fire hazard is a central challenge at national context. How can appropriate management potentially change fire behaviour, fire damage and the difficulty of fire suppression? What are the causal relationships between fire proneness, stand structure and forest stand composition? The common objective of the doctoral research among the five studies is to address the above issues based on principles of creating fire-resistant forests, underlying factors and implications for active forest management, while sustaining effective fire prevention levels. The ultimate goal is to provide forest managers and policy makers with tools to support their decisions, and more effectively align management policies, plans, and practices across fire-prone landscapes. The first research phase aims, across a range of scales from the individual tree to the stand level, respectively: (i) modelling the annual probability of wildfire occurrence of pure and even-aged eucalypt stands; (ii) developing a shrub biomass accumulation model, and (iii) a post-fire mortality model at stand level and the individual tree survival probability to mitigate damage in any forest stand structure. The second phase introduces fire behavior modeling coupled with common stand variables as a tool to (iv) assess potential crown fire occurrence through stand structure/stand composition, and (v) draw guidelines that express the difficulty of fire suppression in those fire-prone forest stands. The accuracy of the research findings can provide an interesting insight to support hazard-reduction silvicultural practices in Portuguese ecosystems

Els pagaments dels serveis ecosistèmics (PSE) han estat promoguts des de la dècada dels noranta per institucions globals, ONGs de conservació i governs nacionals i regionals per incentivar els propietaris a mantenir la biodiversitat i la cobertura forestal, així com per restaurar o millorar la prestació de serveis ecosistèmics. PES ha penetrat a l’agenda de polítiques globals mediambientals perquè promet un enfocament de conservació directa que aborda simultàniament la protecció del medi ambient i la reducció de la pobresa. Amèrica Llatina predomina l’implementació del PES, amb els programes nacionals de Costa Rica (1998) i Mexico (2003) sent dos dels sistemes més grans del món, seguits del programa de conversió de terres inclinades de la Xina. Malgrat la creixent popularitat del PES, segueix sent un concepte controvertit i dinàmic que planteja moltes preocupacions, incloent-hi la monetització de les funcions dels ecosistemes, els compromisos entre l’eficàcia ambiental i les consideracions d’equitat i els possibles riscos d’amuntegament de la motivació. disminuir les motivacions proambientals. Mitjançant un enfocament multidisciplinari i de mètodes mixts, aquesta tesi contribueix a aquests debats investigant com s’ha conceptualitzat i implementat el PES a Colòmbia, un dels que es troben més tard a l’agenda del PSE, que es distingeix globalment tant pel seu alt nivell de biodiversitat com per la seva taxes de deforestació. Aquesta tesi fa dues contribucions principals a la literatura del PSE: en primer lloc, teòricament es mostra la importància d’identificar els punts de convergència entre els discursos del PSE per facilitar l’implementació del SPO segons les necessitats i realitats locals. També destaca el paper important de les motivacions en l’eficàcia de les polítiques de conservació que tenen com a objectiu canvis de comportament. En segon lloc, metodològicament, avança la metodologia Q desenvolupant un protocol sistemàtic i replicable per capturar, definir i prioritzar les declaracions PES de les xarxes socials. També proposa que les motivacions i els comportaments s’analitzin per separat i no s’assumeixin com a intercanviables.Los Pagos por Servicios Ambientales (PSA) han sido promovidos desde la década de 1990 por instituciones globales, ONG conservacionistas y gobiernos nacionales y regionales para incentivar a los propietarios de tierras a conservar la biodiversidad y las coberturas forestales, así como a restaurar o mejorar la provisión de servicios ecosistémicos. Los PSA han permeado la agenda de la política ambiental global porque prometen un enfoque de conservación directo que aborda simultáneamente la protección del medio ambiente y la reducción de la pobreza. América Latina domina la implementación de PSA, y los programas nacionales de Costa Rica (1998) y México (2003) son dos de los esquemas más grandes del mundo, seguidos por el programa de Sloping Land Conversion de China. A pesar de la creciente popularidad de los PSA, éste sigue siendo un concepto controvertido y dinámico que plantea muchas inquietudes, incluida la monetización de las funciones de los ecosistemas, las posibles tensiones entre la efectividad ambiental y las consideraciones de equidad, y los riesgos potenciales de que los PSA disminuyan las motivaciones pro-ambientales de quienes participan en los esquemas. Utilizando un enfoque multidisciplinario y de métodos mixtos, esta disertación contribuye a estos debates al investigar cómo se ha conceptualizado e implementado el PSA en Colombia, un país que acaba de entrar en la agenda de PSA mundial y que se destaca globalmente por su alto nivel de biodiversidad y tasas de deforestación. Esta tesis hace dos contribuciones principales a la literatura de PSA: en primer lugar, teóricamente muestra la importancia de identificar puntos de convergencia en los discursos de PSA para facilitar la implementación de PSA de acuerdo con las necesidades y realidades locales. También destaca el importante papel de las motivaciones pro-ambientales en la efectividad de las políticas de conservación dirigidas a buscar cambios de comportamiento. En segundo lugar, metodológicamente, avanza la metodología Q mediante el desarrollo de un protocolo sistemático y replicable para capturar, definir y priorizar los objetivos de los PSA mencionados en las redes sociales. También propone que las motivaciones y los comportamientos se deben analizar por separado y no deben ser asumidos como intercambiables.
Payments for ecosystem services (PES) have been promoted since the 1990s by global institutions, conservation NGOs, and both national and regional governments to incentivise landowners to maintain biodiversity and forest cover, as well as to restore or enhance the provision of ecosystem services. PES has permeated the environmental global policy agenda because it promises a direct conservation approach that simultaneously tackles environmental protection and poverty reduction. Latin America dominates PES implementation, with the Costa Rican (1998) and Mexican (2003) national programmes being two of the largest schemes in the world, followed by China’s Sloping Land Conversion programme. Despite the growing popularity of PES, it remains a contested and dynamic concept that raises many concerns including the monetisation of ecosystem functions, trade-offs between environmental effectiveness and equity considerations, and potential risks of motivation crowding, meaning that PES can, over time, diminish pro-environmental motivations. Using a multi-disciplinary and mixed methods approach, this dissertation contributes to these debates by investigating how PES has been conceptualised and implemented in Colombia, a late-comer in the PES agenda which stands-out globally for both its high level of biodiversity and its rates of deforestation. This thesis makes two main contributions to PES literature: first, theoretically it shows the importance of identifying points of convergence across PES discourses to facilitate PES implementation according to local needs and realities. It also highlights the important role of motivations in the effectiveness of conservation policies aiming at behavioural changes. Second, methodologically, it advances Q-methodology by developing a systematic and replicable protocol to capture, define and prioritise PES statements from social media. It also proposes that motivations and behaviours should be analysed separately and not assumed as interchangeable.

Abstract Grazing by reindeer (Rangifer tarandus L.) affects vegetation and soil microbial processes in tundra ecosystems. It is considered that grazing can induce two alternative vegetation states that differ in plant species composition and the rate of nutrient cycling. I hypothesised that these alternative vegetation states differ in ecosystem responses to climate warming. I tested the hypothesis using a factorial warming and fertilisation experiment on long-term lightly grazed (LG) and heavily grazed (HG) tundra. The reindeer grazing induced vegetation shift from dwarf shrubs to graminoids increased microbial activities for SOM decomposition. The grazer-induced shifts in vegetation and microbial activities in combination with the fertilisation via urine and faeces had important consequences on soil N availability and soil C quality that determined the ecosystem-level consequences of climate warming. Due to higher soil N availability, warming increased plant productivity (GEP) on HG but not on LG tundra, where N limitation prevented the warming-increased plant production. The varying effects of warming on GEP at different grazing intensities determined the effects of warming on ecosystem net C sink, which was unaffected by warming on HG but decreased on LG tundra. Reindeer grazing reduced the soil C quality, as soils under LG stored a higher proportion of carbohydrates vulnerable to microbial decomposition than soils under HG. According to laboratory soil incubations, the grazer-induced reduction in soil C quality mitigated the responses of soil microbial activity to prolonged warming. Warming caused a stronger decrease in concentrations of phenolics, an important means of plant defence against biotic and abiotic stresses, in Empetrum nigrum ssp. hermaphroditum under HG than LG. Grazing history by reindeer, with the associated vegetation shift from dwarf shrubs to graminoids, can significantly alter the ecosystem-level consequences of climate warming. Overall, this thesis highlights that the effects of reindeer grazing on soil properties, soil N availability and C quality, are important determinants of the ecosystem responses to climate warming. Therefore, future research on climate warming should take into account herbivores and aim towards a more holistic approach that includes both aboveground and belowground components of the ecosystemTiivistelmä Tundralla porolaidunnus vaikuttaa kasvillisuuteen ja maaperän mikrobien toimintaan. Porolaidunnus voi aikaansaada kaksi vaihtoehtoista kasvillisuuden tilaa, jotka eroavat toisistaan paitsi kasvilajiston myös ravinnekierron suhteen. Esitin hypoteesin, jonka mukaan ilmaston lämpenemisen vaikutukset eroavat tundratyypeillä, jotka edustavat vaihtoehtoisia kasvillisuustiloja. Testasin hypoteesia faktoriaalisen lämmitys- ja lannoituskokeen avulla tundra-alueilla, joilla poron laidunnuspaine on ollut pitkäaikaisesti joko kevyttä tai voimakasta. Poron aiheuttama kasvillisuusmuutos varpuvaltaisesta heinävaltaiseksi lisäsi maaperän mikrobien hajotusaktiivisuutta. Poron aiheuttamat erot kasvillisuudessa ja mikrobiaktiivisuuksissa yhdessä virtsan ja papanoiden lannoittavan vaikutuksen kanssa muuttivat maaperän typen saatavuutta sekä hiilen laatua. Erot maaperän ominaisuuksissa puolestaan ohjasivat ilmaston lämpenemisen ekosysteemitason vaikutuksia. Lämmitys kasvatti ekosysteemituotantoa ravinteikkaalla voimakkaasti laidunnetulla tundralla mutta ei kevyesti laidunnetulla tundralla, joka oli typpirajoitteinen. Lämmityksen erilaiset vaikutukset ekosysteemituotantoon eri laidunpaineissa määrittivät lämmityksen vaikutuksen ekosysteemin hiilinieluun, joka pysyi muuttumattomana voimakkaasti laidunnetulla tundralla mutta pieneni kevyesti laidunnetulla tundralla. Porolaidunnus alensi maaperän hiilen laatua, ja kevyesti laidunnetulla tundralla maaperässä oli enemmän mikrobien hajotukselle alttiita hiilihydraatteja kuin voimakkaasti laidunnetulla tundralla. Laboratoriossa suoritetun inkubaatiokokeen perusteella maaperän hiilen alhaisempi laatu lievensi mikrobien hajotusaktiivisuuden vastetta pitkäaikaiseen lämmitykseen. Lämmitys vähensi pohjanvariksenmarjan fenoliyhdisteiden, jotka ovat tärkeä osa kasvien puolustusta bioottisia ja abioottisia stressitekijöitä vastaan, pitoisuuksia enemmän voimakkaasti kuin kevyesti laidunnetulla tundralla. Poron laidunnushistoria yhdessä kasvillisuusmuutoksen kanssa voi merkittävästi vaikuttaa ilmaston lämpenemisen ekosysteemitason seurauksiin. Tämän väitöstyön tulokset osoittavat, että poron vaikutukset maaperän typpeen ja hiileen määrittävät lämpenemisen vaikutukset ekosysteemissä. Tulevaisuudessa ilmastonmuutostutkimuksen pitäisikin kokonaisvaltaisemmin huomioida sekä herbivorian että ekosysteemin eri osien merkitys

This book illustrates the main results deriving from fourteen studies, dealing with the impact of climate change on different agricultural and natural ecosystems, carried out within the Impact of Climate change On agricultural and Natural Ecosystems (ICONE) project funded by the ALFA Programme of the European Commission. During this project, a common methodology on several Global Change-related matters was developed and shared among members of scientific communities coming from Latin America and Europe. In order to facilitate this interdisciplinary approach, specific mobility programmes, addressed to post-graduate, Master and PhD students, have been organized. The research, led by the research groups, was focused on the study of the impact of climate change on various environmental features (i.e. runoff in hydrological basins, soil erosion and moisture, forest canopy, sugarcane crop, land use, drought, precipitation, etc). Integrated and shared methodologies of atmospheric physics, remote sensing, eco-physiology and modelling have been applied.

Post-glacial aquatic ecosystems in Eurasia and North America, such as the Baltic Sea, evolved in the freshwater, brackish, and marine environments that fringed the melting glaciers. Warming of the climate initiated sea level and land rise and subsequent changes in aquatic ecosystems. Seminal ideas on ancient developing ecosystems were based on findings in Swedish large lakes of species that had arrived there from adjacent glacial freshwater or marine environments and established populations which have survived up to the present day. An ecosystem of the first freshwater stage, the Baltic Ice Lake initially consisted of ice-associated biota. Subsequent aquatic environments, the Yoldia Sea, the Ancylus Lake, the Litorina Sea, and the Mya Sea, are all named after mollusc trace fossils. These often convey information on the geologic period in question and indicate some physical and chemical characteristics of their environment. The ecosystems of various Baltic Sea stages are regulated primarily by temperature and freshwater runoff (which affects directly and indirectly both salinity and nutrient concentrations). Key ecological environmental factors, such as temperature, salinity, and nutrient levels, not only change seasonally but are also subject to long-term changes (due to astronomical factors) and shorter disturbances, for example, a warm period that essentially formed the Yoldia Sea, and more recently the “Little Ice Age” (which terminated the Viking settlement in Iceland).There is no direct way to study the post-Holocene Baltic Sea stages, but findings in geological samples of ecological keystone species (which may form a physical environment for other species to dwell in and/or largely determine the function of an ecosystem) can indicate ancient large-scale ecosystem features and changes. Such changes have included, for example, development of an initially turbid glacial meltwater to clearer water with increasing primary production (enhanced also by warmer temperatures), eventually leading to self-shading and other consequences of anthropogenic eutrophication (nutrient-rich conditions). Furthermore, the development in the last century from oligotrophic (nutrient-poor) to eutrophic conditions also included shifts between the grazing chain (which include large predators, e.g., piscivorous fish, mammals, and birds at the top of the food chain) and the microbial loop (filtering top predators such as jellyfish). Another large-scale change has been a succession from low (freshwater glacier lake) biodiversity to increased (brackish and marine) biodiversity. The present-day Baltic Sea ecosystem is a direct descendant of the more marine Litorina Sea, which marks the beginning of the transition from a primeval ecosystem to one regulated by humans. The recent Baltic Sea is characterized by high concentrations of pollutants and nutrients, a shift from perennial to annual macrophytes (and more rapid nutrient cycling), and an increasing rate of invasion by non-native species. Thus, an increasing pace of anthropogenic ecological change has been a prominent trend in the Baltic Sea ecosystem since the Ancylus Lake.Future development is in the first place dependent on regional factors, such as salinity, which is regulated by sea and land level changes and the climate, and runoff, which controls both salinity and the leaching of nutrients to the sea. However, uncertainties abound, for example the future development of the Gulf Stream and its associated westerly winds, which support the sub-boreal ecosystems, both terrestrial and aquatic, in the Baltic Sea area. Thus, extensive sophisticated, cross-disciplinary modeling is needed to foresee whether the Baltic Sea will develop toward a freshwater or marine ecosystem, set in a sub-boreal, boreal, or arctic climate.

The purpose of this book is based on the principles of precaution and solidarity. Its main objective is to contribute to the activities of prevention, preparedness and response to environmental accidents in port areas, from the ecosystem point of view. Studies on risk perception surveys, on causes and consequences of accidents, and about people´s behavior during these accidents, are useful to enrich risk management programs, and emergency plans. This content was elaborated based on the postgraduate studies in Environmental Sciences at USP/SP, and the post-doctorate in Psychology at PUC/SP. All of them involved analysis of environmental accidents in port areas of São Sebastião and Santos (SP), and risk perception surveys. Adds to this the author's 30-year experience at the environmental agency of São Paulo state (1988/2018). This book comments on 60 accidents, technological and/or influenced by natural phenomena, in the Brazilian ports and abroad, from 1900/2019. There were highlighted topics such as: people´s reactions in dangerous situations, social and environmental consequences, risk perception of effects on human health, and oily fauna, among others. The work concludes that people which are very curious, opportunistic and reckless can amplify the consequences of these episodes. It highlights that cautious, supportive and altruistic people help to minimize them, when they act with knowledge, discernment and goodwill. The investments in prevention and preparedness have helped to reduce the number of accidents and it´s severity, so they should have continuity, in an effort that catastrophic situations do not repeat.

Sea otters are the only fully marine-living mustelid and the smallest extant marine mammal. They have the highest mass-specific metabolic rate of any marine mammal, which coupled with the lack of blubber for insulator and energy storage, relegates them to operating as an extreme income strategist, and appears to have led to a life history tactic in which pregnancy rate is fixed while reproductive success varies with the mother’s body condition at the time of birth, which triggers a decision immediately post-partum to care for or abandon her pup. When resources are limiting, sea otters assume highly individualized diets, which are inherited matrilineally. Sea otters exert strong limiting influences on their macroinvertebrate prey, leading to far reaching indirect effects on the structure and function of coastal marine ecosystems. This chapter reviews and synthesizes the interplay between sea otter energetics and life histories, diet and foraging behaviour, and ecosystem influences.

AbstractIn modern societies, the rampant growth of data management technologies—that have access to data sources from a plethora of heterogeneous systems—enables data analysts to leverage their advantages to new areas and critical infrastructures. However, there is no global reference standard for data platform technology. Data platforms scenarios are characterized by a high degree of heterogeneity at all levels (middleware, application service, data/semantics, scalability, and governance), preventing deployment, federation, and interoperability of existing solutions. Although many initiatives are dealing with developing data platform architectures in diversified application domains, not many projects have addressed integration in port environments with the possibility of including cognitive services. Unlike other cases, port environment is a complex system that consists of multiple heterogeneous critical infrastructures, which are connected and dependent on each other. The key pillar is to define the design of a secure interoperable system facilitating the exchange of data through standardized data models, based on common semantics, and offering advanced interconnection capabilities leading to cooperation between different IT/IoT/Objects platforms. This contribution deals with scalability, interoperability, and standardization features of data platforms from a business point of view in a smart and cognitive port case study. The main goal is to design an innovative platform, named DataPorts, which will overcome these obstacles and provide an ecosystem where port authorities, external data platforms, transportation, and logistics companies can cooperate and create the basis to offer cognitive services. The chapter relates to knowledge and learning as well as to systems, methodologies, hardware, and tools cross-sectorial technology enablers of the AI, Data and Robotics Strategic Research, Innovation & Deployment Agenda (Milano et al., Strategic research, innovation and deployment agenda - AI, data and robotics partnership.

The term “sustainable development” first appeared as part of discussions regarding the capacity of natural ecosystems to support the current model of economic growth, assuming a strong concern with the preservation of the planet's environmental structures. Initially, these concerns were conceived on a global scale, but soon the need to bring the discussions to the urban locus - the impact of large human agglomerations on the territory and its natural resources - was realized. Thus, the local scale gained importance, since most of the environmental problems originate in the local urban structures and through the lifestyle that they advocate. Cities are serious consumers and degraders of the natural ecosystem, waterproofing soils, polluting the atmosphere, altering the landscape and consuming resources. Based on studies produced by French geographer Cyria Emelianoff and Brazilian economist Henri Acselrad, on the systematization of different representations and practices in urban sustainability, this research paper aims to introduce the design and development of an evaluation model able to assess the degree of sustainability using a techno-material and socio-environmental set of criteria. This model is intended to serve as a benchmark for both the formulation and evaluation of plans, projects and public policies focused on genuine sustainable development.

Some studies include the need for territorial planning to prioritize people's well-being and health. Thus, ecosystem services are essential but urban planning is not adequately evaluating this potential. The coexistence of planning and these considerations allows identifying the land that, having a greater ecosystem contribution, lack adequate protection by planning. This allow their anthropization and, therefore, making that territory and its inhabitants less resilient. The Community of Madrid is taken as a study case, obtaining a cartography that identifies and delimits the different ecosystems. This is possible thanks to the spatial integration of qualitative data on land cover and its environmental characteristics. With this study seeks its greater preservation, evaluating its state by analyzing the main pressures and links between its conditions, quality, and biodiversity, and how it affects the ability of the ecosystem to provide its services.
Keywords: Resilience, ecosystem services, territory, ecosystem vulnerability Diversos estudios recogen la necesidad de que la planificación territorial tenga como prioridad el bienestar y la salud de las personas. Para ello, los servicios ecosistémicos son indispensables pero la urbanística no está evaluando adecuadamente esta potencialidad. La convivencia del planeamiento y estas consideraciones permite identificar suelos que, teniendo un mayor aporte ecosistémico carezcan de una protección adecuada por el planeamiento, permitiendo su antropización y, por ende, haciendo menos resiliente ese territorio y a sus habitantes. Para ello se toma como caso de estudio la Comunidad de Madrid, obteniendo como resultado, una cartografía que identifica y delimita la extensión de diferentes ecosistemas mediante la integración espacial de datos cualitativos sobre la cobertura terrestre y sus características ambientales, y busca su mayor preservación, evaluando su estado analizando las principales presiones y vínculos entre sus condiciones, calidad y biodiversidad, y cómo afecta a la capacidad del ecosistema para proporcionar sus servicios.

Atmospheric precipitations can be an important source of nutrients to open and coastal zones of marine ecosystem. Jickells [1] has published that atmospheric depositions can sup-port 5-25% of nitrogen required to primary production. Bulk atmospheric precipitations have been collected in a rural location at the Black Sea Crimean coast – Katsiveli settlement, and an urban location – Sevastopol city. Samples have been analyzed for inorganic fixed nitrogen (IFN) – nitrate, nitrite, and ammonium. Deposi-tions have been calculated at various space and time scales. The monthly volume weighted mean concentration of IFN increases from summer to winter in both locations. A significant local source of IFN has been revealed for the urban location and this source and its spatial influence have been quantified. IFN deposition with atmospheric precipitations is up to 5% of its background content in the upper 10 m layer of water at the north-western shelf of the Black Sea. Considering Redfield C:N ratio (106:16) and the rate of primary production (PP) in coastal areas of the Black Sea of about 100-130 g C m-2 year-1 we have assessed that average atmospheric IFN depositions may intensify primary production by 4.5% for rural locations, but this value is increased many-fold in urban locations due to local IFN sources.

Approaches integrating environmental management practices have been gaining importance in recent years. Sustainable Land Management (SLM), Ecosystem-based Adaptation (EbA), Ecosystem-based disaster Risk Reduction (Eco-DRR) and Nature-based Solutions (NbS) are widely applied approaches that tackle certain drivers of challenges such as food insecurity, water scarcity, decline in biodiversity and threats to livelihoods, while also considering both human well-being and ecosystem functions and services. Better understanding the similarities, differences and relationships between these approaches helps to improve efficiency in implementation and leverage synergies. By shedding more light on where these approaches align, investments in land-based solutions in response to different types of environmental challenges can be more effectively designed to achieve multiple targets. In response to the United Nations Convention to Combat Desertification (UNCCD) decision 19/COP.14 paragraph 4, the main objective of this report is to understand and elaborate upon the characteristics of SLM, EbA, Eco-DRR and NbS. The report begins with an overview of the historical backgrounds and origins of SLM, EbA, Eco-DRR and NbS. Despite differences in their specific goals and targeted benefits, all approaches aim for the support of biodiversity, land-based ecosystems and ecosystem services and functions, and employ measures to conserve, restore and sustainably use land to support ecosystem services and functions, including SLM technologies. Furthermore, irrespective of their different goals, the projects developed under any approach can generate comparable co-benefits, especially due to their support of biodiversity. The capacity for all these approaches to deliver multiple co-benefits means that projects of each approach can directly contribute to implementing the specific goals of the other approaches as well. Thus, multiple global and national targets, frameworks, strategies and conventions which call for the implementation of one or more of these approaches, can benefit from this report by avoiding duplication and reducing the overall investments necessary to achieve the set targets and goals. This is critical for achieving the ambitious Agenda 2030, including voluntary land degradation neutrality (LDN) targets and climate action under the Paris Agreement. It will also be the case for the post-2020 global biodiversity framework currently under development. The added value that will come from optimizing the links among these approaches extends from national policymakers to the practitioners of SLM, EbA and Eco-DRR projects, which all share the ultimate goal of sustainable development. To capture the coherence and alignment among these approaches, their similarities and differences have been summarized in a conceptual framework. The framework has been designed to help practitioners understand the specific goals of each approach, and to link these to the relevant global and national targets, frameworks, strategies and conventions, which can support monitoring and evaluation as well as reporting processes. The synergies among these approaches are further illustrated based on three case studies in order to demonstrate opportunities for leveraging multiple co-benefits and targets at implementation level irrespective of the different objectives under each. The results of this assessment demonstrate that activities under one approach can be beneficial to achieve the specific goals of other approaches with little additional effort. It is essential for policymakers, project developers and practitioners to recognize that. This is key to the achievement of sustainable development.

Quantum computing is considered the “next big thing” when it comes to solving computational problems impossible to tackle using conventional computers. However, a major concern is that quantum computers could be used to crack current cryptographic schemes designed to withstand traditional cyberattacks. This threat also impacts future automated vehicles as they become embedded in a vehicle-to-everything (V2X) ecosystem. In this scenario, encrypted data is transmitted between a complex network of cloud-based data servers, vehicle-based data servers, and vehicle sensors and controllers. While the vehicle hardware ages, the software enabling V2X interactions will be updated multiple times. It is essential to make the V2X ecosystem quantum-safe through use of “post-quantum cryptography” as well other applicable quantum technologies. This SAE EDGE™ Research Report considers the following three areas to be unsettled questions in the V2X ecosystem: How soon will quantum computing pose a threat to connected and automated vehicle technologies? What steps and measures are needed to make a V2X ecosystem “quantum-safe?” What standardization is needed to ensure that quantum technologies do not pose an unacceptable risk from an automotive cybersecurity perspective?

Healthy and resilient ecosystems underpin our societies and economies. Collapse of just a few ecosystem services such pollination, timber from forests and food from marine fisheries, could result in a global GDP decline of USD 2.7 trillion annually by 2030. We are not investing sufficiently in nature, resulting in an estimated nature funding gap as high as US$800 billion per year. Redirecting financial flows towards nature-positive investments and activities is critical. Multilateral Development Banks (MDBs) play an instrumental role to support a nature-positive future, aligned with the forthcoming post-2020 Global Biodiversity Framework, the G7 Climate, Energy and Environment Ministers Communiqué of May 27th, 2022, and with the Joint Statement on Nature, People, and Planet endorsed by the 10 MDBs at COP27. This Statement included an intention to work towards a joint understanding of the term 'nature positive' in the context of operations and investments and a goal to develop tools and methodologies for tracking 'nature positive' investments across MDB portfolios. This technical note is a first step towards meeting this commitment. This work presents options for defining nature-positive finance, based on definitions and principles identified in a bibliographical review drawing on global expertise and developing frameworks and taxonomies. Acknowledging the variety of institutional and ecological contexts in which MDBs operate, the report offers a menu of options to screen nature-positive activities as well as a variety of approaches to determine the nature-positive contribution to investments. Finally, the report proposes principles for tracking and reporting on these investments.

For school age children on the island of Puerto Rico, the back-to-back hurricane strikes of Irma and Maria were their first experience with the tragedy of hurricanes in Puerto Rico. There is much concern in the general public about the ability of the Puerto Rican forests, like El Yunque, to recover. These concerns reveal common misconceptions about the dynamics of forest ecosystems. The focus of this research is Journey to El Yunque, a middle school curriculum unit that engages students in evidence-based modeling of hurricane disturbance using long-term data about population dynamics after Hurricane Hugo. Research was guided by the following research question: How does engagement in the science of disturbance ecology impact students’ understanding of and appreciation for ecosystems dynamics? Students completed pre and post assessment understanding of ecosystems dynamics and rated the teacher implementation using the Inquiry-Based Science Teaching survey. Based on a paired t-test, students statistically increased their performance from pretest to posttest with an effect size of 0.22. At the teacher level, the Inquiry-Based Instruction score was a statistically significant predictor of the posttest performance. In other words, these results provide evidence that engaging students in the practices of ecology predicted increased understanding of population dynamics.

This report maps the African landscape of Open Science – with a focus on Open Data as a sub-set of Open Science. Data to inform the landscape study were collected through a variety of methods, including surveys, desk research, engagement with a community of practice, networking with stakeholders, participation in conferences, case study presentations, and workshops hosted. Although the majority of African countries (35 of 54) demonstrates commitment to science through its investment in research and development (R&D), academies of science, ministries of science and technology, policies, recognition of research, and participation in the Science Granting Councils Initiative (SGCI), the following countries demonstrate the highest commitment and political willingness to invest in science: Botswana, Ethiopia, Kenya, Senegal, South Africa, Tanzania, and Uganda. In addition to existing policies in Science, Technology and Innovation (STI), the following countries have made progress towards Open Data policies: Botswana, Kenya, Madagascar, Mauritius, South Africa and Uganda. Only two African countries (Kenya and South Africa) at this stage contribute 0.8% of its GDP (Gross Domestic Product) to R&D (Research and Development), which is the closest to the AU’s (African Union’s) suggested 1%. Countries such as Lesotho and Madagascar ranked as 0%, while the R&D expenditure for 24 African countries is unknown. In addition to this, science globally has become fully dependent on stable ICT (Information and Communication Technologies) infrastructure, which includes connectivity/bandwidth, high performance computing facilities and data services. This is especially applicable since countries globally are finding themselves in the midst of the 4th Industrial Revolution (4IR), which is not only “about” data, but which “is” data. According to an article1 by Alan Marcus (2015) (Senior Director, Head of Information Technology and Telecommunications Industries, World Economic Forum), “At its core, data represents a post-industrial opportunity. Its uses have unprecedented complexity, velocity and global reach. As digital communications become ubiquitous, data will rule in a world where nearly everyone and everything is connected in real time. That will require a highly reliable, secure and available infrastructure at its core, and innovation at the edge.” Every industry is affected as part of this revolution – also science. An important component of the digital transformation is “trust” – people must be able to trust that governments and all other industries (including the science sector), adequately handle and protect their data. This requires accountability on a global level, and digital industries must embrace the change and go for a higher standard of protection. “This will reassure consumers and citizens, benefitting the whole digital economy”, says Marcus. A stable and secure information and communication technologies (ICT) infrastructure – currently provided by the National Research and Education Networks (NRENs) – is key to advance collaboration in science. The AfricaConnect2 project (AfricaConnect (2012–2014) and AfricaConnect2 (2016–2018)) through establishing connectivity between National Research and Education Networks (NRENs), is planning to roll out AfricaConnect3 by the end of 2019. The concern however is that selected African governments (with the exception of a few countries such as South Africa, Mozambique, Ethiopia and others) have low awareness of the impact the Internet has today on all societal levels, how much ICT (and the 4th Industrial Revolution) have affected research, and the added value an NREN can bring to higher education and research in addressing the respective needs, which is far more complex than simply providing connectivity. Apart from more commitment and investment in R&D, African governments – to become and remain part of the 4th Industrial Revolution – have no option other than to acknowledge and commit to the role NRENs play in advancing science towards addressing the SDG (Sustainable Development Goals). For successful collaboration and direction, it is fundamental that policies within one country are aligned with one another. Alignment on continental level is crucial for the future Pan-African African Open Science Platform to be successful. Both the HIPSSA ((Harmonization of ICT Policies in Sub-Saharan Africa)3 project and WATRA (the West Africa Telecommunications Regulators Assembly)4, have made progress towards the regulation of the telecom sector, and in particular of bottlenecks which curb the development of competition among ISPs. A study under HIPSSA identified potential bottlenecks in access at an affordable price to the international capacity of submarine cables and suggested means and tools used by regulators to remedy them. Work on the recommended measures and making them operational continues in collaboration with WATRA. In addition to sufficient bandwidth and connectivity, high-performance computing facilities and services in support of data sharing are also required. The South African National Integrated Cyberinfrastructure System5 (NICIS) has made great progress in planning and setting up a cyberinfrastructure ecosystem in support of collaborative science and data sharing. The regional Southern African Development Community6 (SADC) Cyber-infrastructure Framework provides a valuable roadmap towards high-speed Internet, developing human capacity and skills in ICT technologies, high- performance computing and more. The following countries have been identified as having high-performance computing facilities, some as a result of the Square Kilometre Array7 (SKA) partnership: Botswana, Ghana, Kenya, Madagascar, Mozambique, Mauritius, Namibia, South Africa, Tunisia, and Zambia. More and more NRENs – especially the Level 6 NRENs 8 (Algeria, Egypt, Kenya, South Africa, and recently Zambia) – are exploring offering additional services; also in support of data sharing and transfer. The following NRENs already allow for running data-intensive applications and sharing of high-end computing assets, bio-modelling and computation on high-performance/ supercomputers: KENET (Kenya), TENET (South Africa), RENU (Uganda), ZAMREN (Zambia), EUN (Egypt) and ARN (Algeria). Fifteen higher education training institutions from eight African countries (Botswana, Benin, Kenya, Nigeria, Rwanda, South Africa, Sudan, and Tanzania) have been identified as offering formal courses on data science. In addition to formal degrees, a number of international short courses have been developed and free international online courses are also available as an option to build capacity and integrate as part of curricula. The small number of higher education or research intensive institutions offering data science is however insufficient, and there is a desperate need for more training in data science. The CODATA-RDA Schools of Research Data Science aim at addressing the continental need for foundational data skills across all disciplines, along with training conducted by The Carpentries 9 programme (specifically Data Carpentry 10 ). Thus far, CODATA-RDA schools in collaboration with AOSP, integrating content from Data Carpentry, were presented in Rwanda (in 2018), and during17-29 June 2019, in Ethiopia. Awareness regarding Open Science (including Open Data) is evident through the 12 Open Science-related Open Access/Open Data/Open Science declarations and agreements endorsed or signed by African governments; 200 Open Access journals from Africa registered on the Directory of Open Access Journals (DOAJ); 174 Open Access institutional research repositories registered on openDOAR (Directory of Open Access Repositories); 33 Open Access/Open Science policies registered on ROARMAP (Registry of Open Access Repository Mandates and Policies); 24 data repositories registered with the Registry of Data Repositories (re3data.org) (although the pilot project identified 66 research data repositories); and one data repository assigned the CoreTrustSeal. Although this is a start, far more needs to be done to align African data curation and research practices with global standards. Funding to conduct research remains a challenge. African researchers mostly fund their own research, and there are little incentives for them to make their research and accompanying data sets openly accessible. Funding and peer recognition, along with an enabling research environment conducive for research, are regarded as major incentives. The landscape report concludes with a number of concerns towards sharing research data openly, as well as challenges in terms of Open Data policy, ICT infrastructure supportive of data sharing, capacity building, lack of skills, and the need for incentives. Although great progress has been made in terms of Open Science and Open Data practices, more awareness needs to be created and further advocacy efforts are required for buy-in from African governments. A federated African Open Science Platform (AOSP) will not only encourage more collaboration among researchers in addressing the SDGs, but it will also benefit the many stakeholders identified as part of the pilot phase. The time is now, for governments in Africa, to acknowledge the important role of science in general, but specifically Open Science and Open Data, through developing and aligning the relevant policies, investing in an ICT infrastructure conducive for data sharing through committing funding to making NRENs financially sustainable, incentivising open research practices by scientists, and creating opportunities for more scientists and stakeholders across all disciplines to be trained in data management.
