Résumé :

The impact of natural disasters is often exacerbated by a disparity between resources for relief and recovery. When the barrio of Punta Santiago in Puerto Rico was devastated by Hurricane Maria in September of 2017, many of its residents lived in the remains of their homes for over a year while they rebuilt from wind damage and flood waters that rose over 6 feet. As climate change leads to an even more constrained timeline for response with increasingly frequent and intense storms, the future of Punta Santiago and other coastal communities worldwide will necessitate strategies ranging from nat

Résumé :

Our world is subjected to a panoply of drivers of change. In this context, the understanding on how our biosphere resists, absorbs or is altered by the changes, appears as a hot question in ecology. In this respect, two ecological concepts appear as essential, resilience and biotic interactions. Resilience is related to how ecosystems persist under stress or suffering disturbances. Interactions among species are to a large part responsible for the delivery of ecosystem functions, and form the architecture of biodiversity. Moreover, a substantial part of ecosystem resilience is founded on speci

As urban populations continue to grow around the world, cities and their residents become increasingly vulnerable to climate change risks. Detrimental impacts on natural ecosystems have been observed in the built environment, as well as poorer quality of life. As urban areas are characterised by complex adaptive systems, the concept of ecosystem services represents an important tool for the management of urban socio-environmental quality and can be applied to climate change adaptation and mitigation strategies.

In response to growing global impact on ecosystems, we design programs for conservation and restoration to maintain and enhance biodiversity, productivity and ecosystem resilience. To ensure the greatest return for these programs, there is an implicit requirement for identifying and understanding the complex non-linear relationships that can exist between impact gradients, ecosystem structure and the processes that mediate the two. Ecological resilience theory has developed as one of the fundamental explanations of this complexity. The application of ecological resilience theory in a local man

This research examines the healthcare services ecosystem and the impact and role service interventions made by providers and patients have on this ecosystem. Each area has an important role in contributing to the value and sustainability of the ecosystem. Healthcare, as a community service, requires a minimum of two counterparts: the providers and the customers, in this case the patients. Healthcare is a unique ecosystem because often the customers are not conscious of the interplay of the ecosystem but are reliant upon the system for their health and wellbeing.

Résumé :

Consideration of scale and ecosystem resilience is integral to any conceptual model of the effects of disturbance on ecosystems. Organisms, populations, communities, and ecosystems are differentially affected by disturbance based on the scale at which they occupy the landscape. Scale of observation influences perceptions about ecosystem resilience. There is no single correct scale at which ecological phenomena should be studied, and management decisions require the interfacing of phenomena that occur on very different scales of space and time.

Résumé :

Bacteria are immensely diverse and hold key-positions in essentially all biogeochemical cycles. In freshwater ecosystems, bacteria degrade and mineralize organic compounds, linking the pool of dissolved organic matter to higher trophic levels. Aware of the global biodiversity loss, ecologists have started identifying the relationship of diversity and ecosystem functioning. Central to this is the question if species can functionally replace other species, hence being functionally redundant. Functional redundancy might allow communities to maintain functioning when diversity is lost. Due to thei

Résumé :

Just like in the rest of the world, the urban population in Sweden is increasing each year, which means that cities are becoming increasingly densified and natural green areas are claimed and used for built environment. As a result, biodiversity in cities is often low and inhabitants risk facing losses of ecosystem services of various kinds. As a counterforce to these challenges linked to urbanization, urban agriculture has become an increasingly popular and growing phenomenon in Sweden in recent years.

Future global change scenarios predict a dramatic loss of biodiversity for many regions in the world, potentially reducing the resistance and resilience of ecosystem functions. Once before, during Plio-Pleistocene glaciations, harsher climatic conditions in Europe as compared to North America led to a more depauperate tree flora.

Résumé :

Climate change is rapidly reducing the Arctic Ocean summer sea ice cover, consequently altering the patterns of primary production, with reducing ice algal-, but increasing phytoplankton primary production. As benthic consumers rely on the sinking phytodetritus for food, changes to food availability could render the benthos vulnerable if they prefer ice algae as a food source. The aim this thesis was to investigate the benthic macroinfaunal dietary reliance on ice algae and phytoplankton in North Water Polynya (NOW) and Lancaster Sound (LS) in Canadian Arctic Archipelago, and how a shift from

Résumé :

Ecosystem services are essential for human climate adaptation. As climate change is a direct driver of change for ecosystem service provisioning, it is of importance to care for our ecosystems to be able to cope with future challenges. Local governance has a central role in climate adaptation due to its responsibility in physical planning. To be able to plan for changes driven by climate change, a flexible, adaptive strategy is necessary. Ecosystem-based Adaptation, EbA, can provide this flexibility to an overall adaptation strategy. In this case study, the potential of EbA to help Nature-base

Résumé :

This thesis aims at defining the connection between the increasingly popular ecosystem services theory and its practical implications for sustainable development in Swedish physical spatial planning. A literature study was made to summarize the ecosystem services and resilience thinking concepts (with an emphasis on ecosystem services), their definitions and potential uses in physical spatial planning. This overview was then applied in choosing a concept framework to be tested in a case-study: the possible changes in ecosystem services and their values in a land-use trade off situation. To gat

Résumé :

Land-use change is the single most important global driver of changes in biodiversity. Such changes in biodiversity, in turn, are expected to influence the functioning of ecosystems and their resilience to environmental perturbations and disturbances. It is widely recognised that the use of functional traits and functional diversity is best for understanding the causes and functional consequences of changes in biodiversity, but conceptual development has outpaced empirical applications. This thesis explores these ideas in grazing systems, which are expected to undergo rapid intensification of

Résumé :

An examination was undertaken of the literature and restoration cases for 4 major Australian vegetation types (sclerophyll; rainforest; grassland; and wetland) to explore the proposition that ecological resilience may govern recovery after anthropogenic damage, and/or provide a fundamental guide and measure of success for ecological restoration. Also, primary data were collected from highly degraded sites (5 sclerophyll, 3 rainforest, and 4 grassy sites) to assess recovery after restoration treatment. These were supplemented with questionnaire data from practitioners working at a wider range o

Résumé :

This thesis presents a novel theoretical framework for integrating the environmental and recreation functions of public parks into a coherent planning approach. This framework, which combines insights from urban ecological and human health resilience theory, is firstly applied to discuss how parks can best facilitate key ecosystem services. Using a case study in Perth’s outer suburbs, the framework is then used to investigate how opportunities for community sport might be best provided alongside these services.

Résumé :

L’anthroposystème pastoral du Ferlo sénégalais évolue dans un milieu historiquement négligé par les politiques agricoles en raison de ses caractéristiques biophysiques particulières, peu favorables à l’agriculture et à une forme de mise en valeur autre que l’élevage extensif, incluant une transhumance. Celui-ci permet d’exploiter des ressources très variables dans l’espace et dans le temps. Cette primauté de l’élevage itinérant est de nos jours de plus en plus contestée par le développement de l’agriculture dans un contexte marqué par l’amélioration des conditions de la pluviosité dans tout le
