ENGLISH ABSTRACT: South Africa has made a remarkable transformation from an openly racist to a tolerant and democratic nation. The transformation process removed the legal barriers between subgroups that formerly postulated separate development for the various racial groups and restricted the contact between individuals to a major extent. In present day society, one can observe the transformation process in that South African citizens from different backgrounds have to develop new patterns of communication and interaction. This process was mirrored in the student culture of Stellenbosch. The first objective of this study was to research how individual students experienced their social and academic environment. Since student relations do not always conform to the University norm of mutual respect for human diversity, the University felt the need to facilitate an intervention for valuing human diversity. The second objective of this study was to evaluate the process of the intervention, focusing on the programme context, the programme activities and the program theory. In addition, the impressions of workshop participants were studied. In order to conceptualise the research objectives, the theoretical principles of valuing diversity were discussed in the form of a purposive literature review on the social psychology and sociology of stereotyping and related processes, which were examined as barriers to valuing diversity. The Value Diversity Intervention was implemented in August 2001. The intervention aimed to heighten students' awareness of the diversity of the student body and to improve the interaction among the various student subgroups. The intervention was designed as a workshop and included 50 students from various backgrounds who were living in the University residences. Two evaluation types were utilised in this study, i.e. the evaluation of perceived needs and the evaluation of the intervention process. The research questions were clarified and the specific methods for gathering and analysing the data were specified. In addition, the aspect of validity and the quality of the obtained data were reviewed. The evaluation of perceived needs showed that individual students perceived the student population to be divided into minority ('coloured', 'black') and majority ('white') groups. Even though group membership did not affect specific instances of intergroup relations (e.g. individual friendships), it had implications for the social atmosphere on campus, which was characterised by a lack of intergroup contact and a domination by the majority group. Accordingly, minority group members interpreted the social atmosphere more negatively than majority group members. Hence, minority group members perceived a need to improve intergroup interaction. This analysis indicates that a value diversity intervention may be beneficial. This corresponded to the view of the Department of Student Affairs, which arranged the Value Diversity Intervention. The evaluation of the intervention highlighted both negative and positive aspects. Firstly, the intervention design did not include the promotion of the intervention itself, which might have been essential making students interested in the diversity topic and in motivating students to participate. Secondly, the intervention did not address the specific diversity challenges as experienced by students of the University of Stellenbosch. Students expressed concerns regarding the applicability of the provided information in their daily life. Thirdly, the workshop focused mainly on stereotypes. Yet, the possible effects of stereotypes were not sufficiently discussed. In addition, a large number of stereotypes were listed, but these were often biased due to the lack of participants from diverse groups. Further, no workshop technique which questioned the presented lists of biased stereotypes was applied or generated. Besides these technical considerations, it should be noted that stereotypes in general perpetuate the division between subgroups. Thus, the workshop focused to a large extent on past and present aspects, which divide the student population, instead of focusing on uniting issues. The described negative aspects might have been balanced by one of the four observed workshops. This specific workshop was characterised by a small amount of participants and a positive presentation of one of the main facilitators. This resulted in a productive discussion, where the participants used the possibility to reflect on the current situation out of their perspective and reflected upon the contributions of the facilitator. Students might have been motivated to take positive impulses of this workshop in their daily life. Based upon this research, recommendations can be determined. Firstly, the promotion of the intervention should emphasize the desirability of diversity values and highlight the personal potential benefits to participants. Secondly, it might be useful to acknowledge differences between students, but to place a greater emphasis on similarities, i.e. on aspects that connect students. Thirdly, the curriculum of the intervention should be modified to cater especially for student needs. Fourthly, the selected workshop components should achieve an equal balance between lecture parts and interactive elements. Participants should have the possibility to take an active part in the intervention if they are interested in doing so. The final recommendation entails that future interventions should be based on a comprehensive, sustained strategy with long-term goals. These strategies should be integrated in the already existing infrastructure of an institution. This intervention has to be understood as a contribution to the transformation process that South Africa is currently undergoing. Based on the recent discussion at the University of Stellenbosch about the adoption of a comprehensive diversity strategy, it is hoped that this singular intervention will be linked to further contributions in this transformation process.
AFRIKAANSE OPSOMMING: Suid Afrika het 'n merkwaardige transformasie vanaf 'n openlik rassistiese tot 'n tolerante en demokratiese nasie ondergaan. Voorheen het die wetlike skeiding tussen subgroepe aparte ontwikkeling en, vir verskeie rassegroepe, minimale kontak met individue in verskillende rassegroepe beteken. Die transformasieproses in Suid-Afrika het hierdie omstandighede verander en in die huidige Suid-Afrikaanse samelewing is die proses waardeur mense van verskillende agtergronde nuwe patrone van kommunikasie en interaksie moet ontwikkel, merkbaar. Die transformasieproses kan ook in die studentekultuur van Stellenbosch gesien word. Die eerste doel van die tesis was om ondersoek in te stel na hoe individuele studente hulle sosiale en akademiese omgewing ervaar. Aangesien studenteverhoudinge nie altyd tot die Universiteit se norm van wedersydse respek vir menslike diversiteit konformeer nie, het die Universiteit gevoel dat daar 'n behoefte is om 'n intervensie te fasiliteer om waardering vir menslike diversiteit skep. Die tweede doel van die tesis was om die proses van die intervensie te evalueer deur te fokus op die konteks van die program, die programaktiwiteite en die programteorie. Verder is die indrukke van die deelnemers aan die werkswinkelook bestudeer. Die teoretiese beginsels onderliggend aan die waardering van diversiteit is bespreek ten einde die navorsingsdoelwitte te konseptualiseer. Dit is verwesenlik deur 'n "doelgerigte" literatuurstudie oor die sosiale sielkunde en sosiologie van stereotipering en verwante prosesse wat gesien word as struikelblokke in die evaluering van diversiteit. Die intervensie vir die waardering van diversiteit is in Augustus 2001 deur die Universiteit van Stellenbosch geimplimenteer. Die intervensie het as doel gehad om studente 'n verhoogde gewaarwording van die diversiteit van die studenteliggaam te bied en ook om interaksie tussen die verskeie studente-subgroepe te bevorder. Die intervensie is ontwerp as 'n werkswinkel vir 50 studente van verskillende agtergronde wat van Universiteitsbehuising gebruik maak. Die tesis verduidelik hoe die navorsingsdoelwitte korrespondeer met die evalueringstipes wat gebruik is, nl. die evaluasie van waargenome behoeftes en die evaluasie van die proses. Die navorsingsvrae is duidelik gestel en die wetenskaplike metodes vir dataversameling en dataanalise word gespesifiseer. Verder word die aspek van die geldigheid en kwaliteit van die data ook bespreek. Die evaluering van waargenome behoeftes het gewys dat individuele studente die studentepopulasie sien as verdeel In 'n minderheidsgroep ('bruin' en 'swart') en 'n meerderheidsgroep ('wit'). Alhoewel lidmaatskap tot n betrokke groep rue intergroepverhoudings affekteer nie (bv. individuele vriendskappe), het dit tog implikasies vir die sosiale atmosfeer op kampus wat deur 'n tekort aan intergroepkontak en dominasie deur die meerderheidsgroep gekarakteriseer kan word. Vervolgens interpreteer minderheidsgroepe die sosiale atmosfeer meer negatief as lede van die meerderheidsgroep. Dit kan dan ook as die rede aangevoer word waarom lede van minderheidsgroepe 'n waargenome behoefte het om intergroepinteraksie te bevorder. Die persepsies van die respondente wat 'n onderhoud toegestaan het, het aangedui dat 'n intervensie vir die waardering van diversiteit voordelig sal wees en dit het ooreengestem met die siening van die Departement van Studentesake, wat die intervensie gereël het. Die evalusie van die intervensie beklemtoon albei die negatiewe en positiewe aspekte. Eerstens, het die intervensie intervensie-ontwerp, nie die promosie van die intervensie self behels nie, wat noodsaaklik sou gewees het om student geinteresseerd te maak in die diversiteit van die onderwerp en om die studente te motiveer om mee te doen. Tweedens, het die intervensie nie die spesifieke uitdagings soos deur die studente van die Universiteit van Stellnbosch ondervind is, aangespreek nie. Studente het hulle bekommernis uitgespreek oor die toepassing van die informasie in hulle daaglikse lewe. Derdens het die werkswinkel hoofsaaklik gefokus op stereotipes. Nogtans was die effekte van die stereotipes nie deeglik bespreek nie. Boonop was daar te groot aantal stereotipes gelys, maar dit was bevooroordeeld as gevolg van die gebrek van deelnemer van diverse groepe. Daar was ook geen werkswinkel tegnieke van toepassing wat die aangebode lyste van die bevooroordeelde stereotipes bevraagteken het nie. Naas die tegniese oorwegings, moet daar gelet word dat stereotipes in die algemeen die verdeling tussen subgroepe in stand hou van stereotipes in die algemeen. Dus het die werkswinkel tot 'n groot mate gefokus op huidige en vorige aspekte wat die studente verdeel het in plaas daarvan om te fokus op sake van ooreenstemming. Gegrond op hierdie navorsing, kan aanbevelings gemaak word. Eerstens moet daar klem gelê word op die bevordering van die verskeie behoeftes en waardes van die intervensie en die potensiaal waarby deelnemers kan baat. Tweedens, kan dit waardevol wees om verskille tussen studente te erken maar groter klem te lê op eendersheid, d.i. aspekte wat die studente tot mekaar verbind. Derdens moet die leerplan van die intervensie gewysig word om in die behoeftes van die student te voorsien. Vierdens, moet daar 'n balans gehandhaaf word tussen die lesings en interaktiewe elemente. Daar moet 'n moontlikheid bestaan vir deelnemers om 'n aktiewe rol in die intervensie te speel indien hulle dit verlang. Ten slotte word aanbeveel dat toekomstige intervensie gebaseer word op begrypende en volgehoue strategie met lang termyn doelwitte. Die bogenoemde strategie moet in die alreeds bestaande infrastruktuur verweef word. Hierdie intervensie kan beskou word as 'n bydrae tot die transformasie proses wat Suid-Afrika huidiglik ondergaan. Gebaseer op die onlangse gesprek by die Universiteit van Stellenbosch oor die aanneming van'n omvattende diversiteitstrategie, word daar gehoop dat die enkelvoudige intervensie kan inskakel by verdere bydraes in die transformasie proses.

ENGLISH ABSTRACT: Globalisation has led to the use of English lingua franca (ELF) in many international classrooms and in the majority of the South African tertiary education institutions. The South African situation and use of ELF is grounded in the historic developments of the country and an understanding that it is an international requirement for individuals to have access to English language skills to enable them to realise their potential and participate fully within South African society (CHE, 2002:4). While the development of the previously neglected field of African languages as scientific and academic languages remains a priority, examining the use of ELF in the South African tertiary classroom is essential; therefore, this study explores the use of ELF in the South African tertiary education classroom to understand the role of linguistic diversity in the learning environment. Particular attention is directed to the linguistic repertoires of students, their codeswitching behaviour and instances of miscommunication. The study was conducted at a university of technology and participants were observed during group work sessions, which culminated in a formal assessment. Questionnaires were also utilised to gain further data for analysis. Findings indicate that the role of English as a global economic language should not be underestimated. However, the promotion of multilingualism is advocated and attention should be given to not only the promulgation of language policies, but also their implementation. Furthermore, flexibility in language should be encouraged, with a move away from the traditional use of one language for teaching and learning to a translanguaging classroom and an assessment environment, which brings to the forefront the benefits of translanguaging, where one language is used to reinforce and increase understanding in the other languages (Garcia & Wei, 2014:64). This will assist students to reach their full potential in the tertiary education environment.
AFRIKAANSE OPSOMMING: Globalisasie het gelei tot die gebruik van Engelse lingua franca (ELF) in baie internasionale klaskamers, sowel as in die meerderheid van Suid-Afrika se tersiêre onderwysinsitute. Die Suid-Afrikaanse situasie en die gebruik van ELF is gegrond op die historiese ontwikkelings in die land. Elke student moet, om sy volle potensiaal te ontwikkel en volkome deel te wees van die Suid-Afrikaanse gemeenskap, Engels taalvaardig wees, wat in elk geval 'n internasionale vereiste is (CHE, 2002:4). Terwyl die ontwikkeling van Afrika-tale (wat voorheen nie so baie aandag gekry het nie) as 'n wetenskap- en akademiese taal steeds die voorkeur geniet, moet die ondersoek in die gebruik van ELF in die Suid Afrikaanse klaskamers gesien word as ʼn uiters belangrike onderwerp. Hierdie navorsing ondersoek die gebruik van ELF in die Suid-Afrikaanse tersiêre klaskamer. Die doel is dan om die rol van linguistieke diversiteit in die leeromgewing, naamlik die klaskamer, na te vors. Spesifieke aandag is gegee aan die studente se linguistieke vaardighede, kodewisseling en kommunikasiebreuke. Hierdie navorsing is gedoen by 'n universiteit van tegnologie en deelnemers is waargeneem tydens groepwerksessies. Die waarnemings is ten slotte saamgevat in 'n formele assessering. Vraelyste is ook gebruik om inligting te verkry vir verdere ontleding. Bevindings het bewys dat die rol van Engels as ʼn globale ekonomiese taal nie onderskat moet word nie. Alhoewel die bevordering van veeltaligheid bepleit word, moet aandag nie net gegee word aan die teorie van taalbeleide nie, maar ook aan die uitvoering hiervan. Buigsaamheid moet verder in taalonderrig aangemoedig word deur weg te beweeg van die tradisionele gebruik van slegs een taal vir onderrig en leer. Daar behoort dus meer as een taal in die klaskamer en op assesseringsgebiede gebruik te word; dit sal lei tot die versterking en beter verstandhouding tussen tale (Garcia & Wei, 2014:64). Dit sal leerders ondersteun om hulle volle potensiaal te bereik in ʼn tersiêre onderwys-omgewing.

This thesis intends to analyze the influence of diversity in deep-level characteristics of team members on team dynamics. Intragroup conflict (relationship and task conflict) and team cohesiveness are selected as the group dynamics to be studied. Deep-level diversity is investigated with respect to personality traits (extraversion and time-urgency) and values (individualism) of team members. In addition, the moderating effect of time on the diversity- team dynamic relationship is analyzed. For the purpose of testing the hypotheses, a questionnaire study was conducted with 297 individuals from 55 teams, employed in defense and IT companies in Ankara. All analyses were performed at the group level. The results indicated that deep-level diversity in individualism was positively associated with relationship conflict in groups. Contrary to the hypothesis, it was also found that time played a neutralizing role on the effects of deep-level diversity on team conflict

This study focuses on the vegetation of the African city of Bujumbura, Burundi. Urban flora is detailed according to the origin of the species (native or introduced), their life form, the use of these species by the local population and their behaviour (invasive or not).

The correlation between different natural and anthropogenic environmental factors and the composition of plant communities has been demonstrated through the analysis of vegetation plots. Three types of green areas were studied: spontaneous vegetation on terra firma, wetlands

and domestic gardens.

The main ecological factor correlated to the composition of the spontaneous vegetation of terra firma is the degree of urbanization. From the suburb to the city centre, savannah species typical for the region are replaced by alien invasive species, mostly ruderals. The latter generally have a large distribution, often on several continents. The physiognomy of the vegetation also changes, with hemicryptophytes and phanerophytes in the outskirts and the dominance of therophytes and chamaephytes in the city centre.

In most of wetlands, a large proportion of the plant species are natives, but some wetlands are almost totally invaded by alien species. Soil type is the main environmental factor correlated with

the variability of the vegetation.

The flora of domestic gardens is mainly composed of introduced species used as ornamental, food or medicinal plants. The socio-economical status of the neighbourhood is the main factor correlated with the variability of the garden flora. In high standing neighbourhoods, most species are onamental, with many trees and shrubs. In popular neighbourhoods, the flora is mainly utilitarian (vegetables and fruits), with a significant proportion of native species, and composed mainly of annual species.

A small proportion of the alien species cultivated in gardens has become invasive in the semi-natural vegetation of the city and its surroundings. Many other species cultivated in the gardens could become invasive, based on their ecology and their invasive behaviour in other regions with a climate similar to that of Bujumbura.

Overall, the city of Bujumbura has a diverse flora, with many useful species (vegetables and fruits, traditional medicine, construction of fences and roofs, material for mats and art objects.). The vegetation also hosts wildlife: birds, fishes, hippos, crocodiles etc…

In conclusion, the vegetation of Bujumbura contributes to biodiversity conservation and provides services to the urban population, but the expansion of alien invasive species and the consequent homogenization of the vegetation is a challenge for the future.

This study set out to explore and describe the experiences of executives and coaches when going through a process of executive coaching. The rationale was that an understating of their experience and their perceived benefits that they gain from a coaching process, might afford insight into a relatively new field. Subsequently this could perhaps contribute to the knowledge of executive coaching in South Africa and develop the discipline further by focusing on the experiences of the different parties. A qualitative approach was followed since it provides rich, descriptive data that increases the contextual depth. To ensure the quality of the research, sensitivity was given to criteria of transferability, credibility and dependability. Exploratory research was employed because executive coaching in South Africa has not been documented that extensively. This method was also chosen because the researcher aimed to describe and interpret the context-bound research subject. Grounded theory was used to analyse the qualitative data. Ten participants were interviewed individually to collect information regarding their experiences. Five coaches and five coachees were interviewed, the interviews were recorded, transcribed and analysed from a grounded theory perspective. The findings indicated the experiences of coachees and coaches when going through a coaching process. There are five transcending findings that the researcher found very interesting although these were not all linked to the research questions. They are as follows:
1) Approach / focus of coach seems closely linked to experience of coachee
2) Coaches use very different paradigms / models
3) Use the term executive coaching interchangeable with other terms
4) Coach not unaffected by executive coaching relationship
5) Important for the coachee to feel that the coach understands his/her culture The first indicates that the approach of the coach seems closely linked to the experience of the coachee”. The second indicates that coaches use different paradigms and some followed a more involved process. The third indicates that coaches also use different terms to refer to executive coaching which may lead to misunderstandings in the field. The fourth transcending finding indicates that the coach is not unaffected by the coaching relationship and that they also value growth and development from coaching. The last transcending finding indicates that the coachee feels it is important that the coach understands his/her culture and background. This study contributes to the field of coaching, more specifically, executive coaching in South Africa. The findings also stress the importance of understanding and respecting the diversity in South Africa, specifically in terms of our cultures, backgrounds and different frameworks.

Genomic analysis provides a substantial amount of information on evolutionary history, novel genes, transcriptomic expression and regulation in response to environmental stimuli, how efficiently organisms utilize their genome, and directional genome evolution. Genome size analysis serves as the first step in the sequencing process, because sequencing and annotation costs are directly correlated with genome size. Invertebrates represent the vast majority of faunal diversity on the planet, and, to a greater extent, the marine environment, although they are vastly understudied when compared to vertebrate genomes. Flow cytometry is a widely used, reliable, and accurate means of estimating genome sizes and has yielded valid measurements in this comparatively broad taxonomic study. This methodology quantifies genome sizes by measuring the fluorescent re-emission from nuclei that have been saturated with DNA- intercalating dyes, such as propidium iodide. Genome sizes of 19 species across five phyla were estimated by comparison with the known genome size of chicken (Gallus domesticus). Several estimates reported here are the first for their species or class. In addition to estimating new marine invertebrate genome sizes, analyses of some common preservation methods of tissue viability for flow cytometric estimations were performed. Generally, in comparison to RNAlater or ethanol, DMSO-based storage buffer was most successful at preserving nuclear membrane integrity, a requirement for flow cytometric genome size estimations. Recommendations of cost-effective species eligible for current next-generation sequencing technology (<3.5 Gb) are given for invertebrate genomicists seeking potential novel species to sequence.

Diversity is a relative concept, which has been applied to a number of domains, such as culture and biology. A simple measure of diversity is derived by drawing from the domains of biological and cultural diversity, as well as, information retrieval for its measurement capabilities. This domain independent diversity measure can be used to determine diversity between entities in any collection that can be expressed as features and their values. The measurement can be applied to a single feature or to any combination of features. The entities may be, among other things, words in a document, biological species in an environment, people in an organization, or records in a data set. This diversity measure provides a single value for entities in their collection; measuring the relative diversity of the entity with respect to the other entities in the collection. This tool can be used to compare and contrast diversity between collections of entities, or within the same collection over time.

The variability of wind and solar is perceived as a major obstacle in employing otherwise abundant renewable energy resources. Based on the available geographically dispersed data for the WECC U.S. area (excluding Alaska) and eastern U.S., we analyze to what extent the geographic diversity of these resources can offset their variability. It is common to discern baseload (i.e. constantly employed cheaper power generation, as from nuclear and coal plants) from more expensive dispatchable power sources which help meet variable electric load. The spot electricity price depends on the difference between the load and baseload. With significant amounts of power coming from wind and solar, we use generation with low variable cost (GLVC) to include baseload and wind/solar generation. The GLVC will then become variable as well. The electricity price, however, will be determined by the difference between load and GLVC. While the details of future electricity spot-pricing are harder to predict, the overall trend will remain: a higher hourly difference between load and the low-variable-cost generation increases the electricity price. This difference can serve as an approximate measure of the (hourly) revenue from producing electricity. Currently, the variable load follows fairly well defined daily and weekly load cycles. Significant amount of wind-produced power will inevitably alter the cyclic nature for the variable load time-dependence. Additionally, wind and solar farms generation profiles may be expected to poorly correlate with the variable load. We determine the set of wind and PV sites that best matches the load; we also show that the generation from any wind or PV site from the optimal set is positively correlated with the remaining variable load. The geographic distribution of optimal generation sites, e.g. North vs. South, shows features similar to phase transitions.

Abstract Product customization has become an important approach to meet individual customers’ needs. One of major challenges in product customization is to assist customers making informed decisions in terms of the company capability and the value-added by customization. The ramification is not only helping customers selecting the most appropriate products but also helping the company to decide what to design and produce. In this paper, taking into consideration of its diversity, customer value can be measured as the quality utility per unit cost, or the ratio of marginal utility and marginal cost. Customer Value Oriented Product Customization (CVOPC) is developed as a systematic process to quantify the quality utility through guiding customers to make customization choices that reflect the balance of customer-valued quality and cost. A modified conjoint analysis is applied to capture the customer’s utility function of quality in terms of specific product features. A case study of designing module power supplies for a telecommunication system is presented.

There is a growing body of literature that argues that normally women derive little benefit from cash crops. Some of the barriers leading to women having less benefit from cash crop value chains include cultural norms and power differences in access to, and control over, resources among actors in value chains. It is also argued that women’s participation in different forms of collective action help women to increase benefits to them through their increased agency, hence enabling them to utilise existing and diverse options for their empowerment. This paper explores how women have benefited from their engagement in sunflower commercialisation and how culture has influenced changes in access to, and control over, resources, including land, for their empowerment.

Rural economic transformations in Africa are generating new opportunities to engage with agricultural value chains. However, many young people are said to be locked out of such opportunities because of limited access to farmland, which pushes them out of agriculture and rural areas, and/or hinders their autonomy. This framing of the ‘land problem’ imperfectly reflects rural young people’s livelihoods in much of sub-Saharan Africa, and therefore does not provide a solid basis for policy. Policy-relevant discussions must consider the diversity of rural contexts, broader land dynamics and more nuanced depictions of youth engagement with the rural economy.

Tree species are characterized by their perennial growth habit, woody morphology, long juvenile period phase, mostly outcrossing behaviour, highly heterozygosity genetic makeup, and relatively high genetic diversity. The economically important trees have been an integral part of the human life system due to their provision of timber, fruit, fodder, and medicinal and/or health benefits. Despite its widespread application in agriculture, industrial and medicinal values, the molecular aspects of key economic traits of many tree species remain largely unexplored. Over the past two decades, research on forest tree genomics has generally lagged behind that of other agronomic crops. Genomic research on trees is motivated by the need to support genetic improvement programmes mostly for food trees and timber, and develop diagnostic tools to assist in recommendation for optimum conservation, restoration and management of natural populations. Research on long-lived woody perennials is extending our molecular knowledge and understanding of complex life histories and adaptations to the environment, enriching a field that has traditionally drawn its biological inference from a few short-lived herbaceous species. These concerns have fostered research aimed at deciphering the genomic basis of complex traits that are related to the adaptive value of trees. This review summarizes the highlights of tree genomics and offers some priorities for accelerating progress in the next decade.

Nigeria has sought to diversify its economy away from dependence on oil as a major source of government revenue through agricultural commercialisation. Agriculture has been a priority sector because it has very high growth potential and the greatest potential for employment and export revenue. The cocoa and rice value chains are central to the government’s engagement with agriculture to achieve these objectives. This paper sets out to investigate the underlying political economy dynamics of the commercialisation of the cocoa and rice value chains in Nigeria in terms of smallholder farm households’ shift from semi-subsistence agriculture to production primarily for market, and predominantly commercial medium- and large-scale farm enterprises complementing or replacing smallholder farm households.

To deliver infrastructure that sustain our communities, economy, and environment, we must innovate, modernize, and even revolutionize our approach to infrastructure development. Change takes courage, but as one starts down the path of innovation, what was once novel becomes more familiar, more established. The U.S. Army Corps of Engineers (USACE) is walking this path with our partners through the Engineering With Nature (EWN) Initiative, integrating human engineering with natural systems. The International Guidelines on Natural and Nature-Based Features for Flood Risk Management are the next step toward revolutionary infrastructure development—a set of real-world guidelines to help familiarize us with what was once novel. USACE and collaborators around the world have been building, learning, and documenting the best practices for constructing Natural and Nature-Based Features (NNBF) for decades. The consolidation of these lessons into a single guidance document gives decision-makers and practitioners a much-needed resource to pursue, consider, and apply NNBF for flood risk management while expanding value through infrastructure. Relationships and partnerships are vital ingredients for innovation and progress. The NNBF Guidelines was achieved because of the strong relationships in the nature-based engineering community. The magnitude and diversity of contributors to the NNBF Guidelines have resulted in a robust resource that provides value beyond a single agency, sector, or nation. Similarly, the work of incorporating NNBF into projects will require us to strengthen our relationships across organizations, mandates, and missions to achieve resilient communities. I hope you are inspired by the collaborative achievement of the NNBF Guidelines and will draw from this resource to develop innovative solutions to current and future flood risk management challenges. There is a lot we can achieve together along the path of revolutionary infrastructure development.

A great deal of energy can be sourced both directly and indirectly from waste. For example, municipal waste with an energy content of around 60 petajoules is incinerated in Switzerland every year. The energy recovered directly from this waste covers around 4 % of the Swiss energy demand. However, the greatest potential offered by waste management lies in the recovery of secondary raw materials during the recycling process, thus indirectly avoiding the energy-intensive production of primary raw materials. In order to optimise the contribution to the energy turnaround made by waste management, as a first step, improvements need to be made with respect to the transparent documentation of material and cash flows, in particular. On the basis of this, prioritisation according to the energy efficiency of various recycling and disposal channels is required. Paper and cardboard as well as plastic have been identified as the waste fractions with the greatest potential for improvement. In the case of paper and cardboard, the large quantities involved result in considerable impact. With the exception of PET drinks bottles, plastic waste is often not separately collected and therefore offers substantial improvement potential. Significant optimisation potential has also been identified with regard to the energy efficiency of incineration plants. To allow municipal solid waste incineration (MSWI) plants to use the heat they generate more effectively, however, consumers of the recovered steam and heat need to be located close by. A decisive success factor when transitioning towards an energy-efficient waste management system will be the cooperation between the many stakeholders of the federally organised sector. On the one hand, the sector needs to be increasingly organised along the value chains. On the other hand, however, there is also a need to utilise the freedom that comes with federal diversity in order to test different solutions.

Since the early 1980s, the Fogera Plain has been one of Ethiopia's major rice production areas. The introduction of rice, its commercialisation and the subsequent increased surplus production has led to the ability of smallholder rice farmers to intensify their production through diverse investments, mainly in supplementary irrigation. This has also enabled rice farmers to diversify crop production, mainly during the off-season, through the production of high-value crops like vegetables. Despite this expansion, a recent visit to the Fogera Plain by the authors revealed that most smallholder rice farmers were not able to sell their onions due to the collapse of local markets. To investigate this collapse further, this paper follows the authors' investigation of farmer investments in producing onion, their responses to the collapse of the onion market, and the implications for rural livelihood improvement within the Fogera Plain.

The main recommendations of the panel report can be summarised under five key headings:  Building the Scottish Bronze Age: Narratives should be developed to account for the regional and chronological trends and diversity within Scotland at this time. A chronology Bronze Age Scotland: ScARF Panel Report iv based upon Scottish as well as external evidence, combining absolute dating (and the statistical modelling thereof) with re-examined typologies based on a variety of sources – material cultural, funerary, settlement, and environmental evidence – is required to construct a robust and up to date framework for advancing research.  Bronze Age people: How society was structured and demographic questions need to be imaginatively addressed including the degree of mobility (both short and long-distance communication), hierarchy, and the nature of the ‘family’ and the ‘individual’. A range of data and methodologies need to be employed in answering these questions, including harnessing experimental archaeology systematically to inform archaeologists of the practicalities of daily life, work and craft practices.  Environmental evidence and climate impact: The opportunity to study the effects of climatic and environmental change on past society is an important feature of this period, as both palaeoenvironmental and archaeological data can be of suitable chronological and spatial resolution to be compared. Palaeoenvironmental work should be more effectively integrated within Bronze Age research, and inter-disciplinary approaches promoted at all stages of research and project design. This should be a two-way process, with environmental science contributing to interpretation of prehistoric societies, and in turn, the value of archaeological data to broader palaeoenvironmental debates emphasised. Through effective collaboration questions such as the nature of settlement and land-use and how people coped with environmental and climate change can be addressed.  Artefacts in Context: The Scottish Chalcolithic and Bronze Age provide good evidence for resource exploitation and the use, manufacture and development of technology, with particularly rich evidence for manufacture. Research into these topics requires the application of innovative approaches in combination. This could include biographical approaches to artefacts or places, ethnographic perspectives, and scientific analysis of artefact composition. In order to achieve this there is a need for data collation, robust and sustainable databases and a review of the categories of data.  Wider Worlds: Research into the Scottish Bronze Age has a considerable amount to offer other European pasts, with a rich archaeological data set that includes intact settlement deposits, burials and metalwork of every stage of development that has been the subject of a long history of study. Research should operate over different scales of analysis, tracing connections and developments from the local and regional, to the international context. In this way, Scottish Bronze Age studies can contribute to broader questions relating both to the Bronze Age and to human society in general.
