A General Framework for Analyzing Sustainability of Social-Ecological Systems

Abstract: A major problem worldwide is the potential loss of fisheries, forests, and water resources Understanding of the processes that lead to improvements in or deterioration of natural resources is limited, because scientific disciplines use different concepts and languages to describe and explain complex social-ecological systems (SESs) Without a common framework to organize findings, isolated knowledge does not cumulate Until recently, accepted theory has assumed that resource users will never self-organize to maintain their resources and that governments must impose solutions Research in multiple disciplines, however, has found that some government policies accelerate resource destruction, whereas some resource users have invested their time and energy to achieve sustainability A general framework is used to identify 10 subsystem variables that affect the likelihood of self-organization in efforts to achieve a sustainable SES

Adaptive governance of social-ecological systems

Abstract: ▪ Abstract We explore the social dimension that enables adaptive ecosystem-based management. The review concentrates on experiences of adaptive governance of social-ecological systems during periods of abrupt change (crisis) and investigates social sources of renewal and reorganization. Such governance connects individuals, organizations, agencies, and institutions at multiple organizational levels. Key persons provide leadership, trust, vision, meaning, and they help transform management organizations toward a learning environment. Adaptive governance systems often self-organize as social networks with teams and actor groups that draw on various knowledge systems and experiences for the development of a common understanding and policies. The emergence of “bridging organizations” seem to lower the costs of collaboration and conflict resolution, and enabling legislation and governmental policies can support self-organization while framing creativity for adaptive comanagement efforts. A resilient social-eco...

The Strategy of Ecosystem Development

Abstract: The principles of ecological succession bear importantly on the relationships between man and nature. The framework of successional theory needs to be examined as a basis for resolving man’s present environmental crisis. Most ideas pertaining to the development of ecological systems are based on descriptive data obtained by observing changes in biotic communities over long periods, or on highly theoretical assumptions; very few of the generally accepted hypotheses have been tested experimentally. Some of the confusion, vagueness, and lack of experimental work in this area stems from the tendency of ecologists to regard “succession” as a single straightforward idea; in actual fact, it entails an interacting complex of processes, some of which counteract one another.

Panarchy: Understanding Transformations in Human and Natural Systems

Abstract: The book examines theories (models) of how systems (those of humans, nature, and combined humannatural systems) function, and attempts to understand those theories and how they can help researchers develop effective institutions and policies for environmental management. The fundamental question this book asks is whether or not it is possible to get beyond seeing environment as a sub-component of social systems, and society as a sub-component of ecological systems, that is, to understand human-environment interactions as their own unique system. After examining the similarities and differences among human and natural systems, as well as the means by which they can be accounted for in theories and models, the book examines five efforts to describe human-natural systems. The point of these efforts is to provide the means of learning about those systems so that they can be managed adaptively. The final section of the book uses case studies to examine the application of integrated theories/models to the real world.

Ecology: Individuals Populations and Communities

Abstract: A revised and updated edition of this textbook. As before the study of plant and animal ecology is fully integrated and mathematical and laborotory studies are described where necessary. Examples drawn from real ecological systems ilustrate the complexity of this subject and the involvement of diverse areas: descriptive natural history, physiology, behaviour, field experimentation and mathematical modelling. The authors attempt to encourage the reader to combine all the above facets, so that a balanced view emerges. Emphasis is placed on the clear presentation of mathematical aspects and the material aims to be accessible to the undergraduate with little experience and also stimulating to practising ecologists. This new edition contains two new chapters both of which consider areas of applied ecology which are relevant to contemporary global issues. The first considers the control of abundance; on the one hand the limiting of pest and weed populations, on the other, maintaining the biological diversity of endangered species. The second considers large areas as an extension of the discussion of communities. These "ecosystems" in the newest sense of the word are an important field of study when considering some of the important environmental problems facing mankind.
