Knowledge, Learning and the Evolution of Conservation Practice for Social-Ecological System Resilience

There are two broadly conceptualized ways in which conservation knowledge may evolve: the depletion crisis model and the ecological understanding model. The first one argues that developing conservation thought and practice depends on learning that resources are depletable. Such learning typically follows a resource crisis. The second mechanism emphasizes the development of conservation practices following the incremental elaboration of environmental knowledge by a group of people. These mechanisms may work together. Following a perturbation, a society can self-organize, learn and adapt. The self-organizing process, facilitated by knowledge development and learning, has the potential to increase the resilience (capability to absorb disturbance and reorganize while undergoing change) of resource use systems. Hence, conservation knowledge can develop through a combination of long-term ecological understanding and learning from crises and mistakes. It has survival value, as it increases the resilience of integrated social--ecological systems to deal with change in ways that continue to sustain both peoples and their environments.     

Local Ecological Knowledge and Institutional Dynamics for Ecosystem Management: A Study of Lake Racken Watershed, Sweden

The sustainable use of resources requires that management practices and institutions take into account the dynamics of the ecosystem. In this paper, we explore the role of local ecological knowledge and show how it is used in management practices by a local fishing association in a contemporary rural Swedish community. We focus on the local management of crayfish, a common-pool resource, and also address the way crayfish management is linked to institutions at different levels of Swedish society. Methods from the social sciences were used for information gathering, and the results were analyzed within the framework of ecosystem management. We found that the practices of local fishing association resemble an ecosystem approach to crayfish management. Our results indicate that local users have substantial knowledge of resource and ecosystem dynamics from the level of the individual crayfish to that of the watershed, as reflected in a variety of interrelated management practices embedded in and influenced by institutions at several levels. We propose that this policy of monitoring at several levels simultaneously, together with the interpretation of a bundle of indicators and associated management responses, enhances the possibility of building ecological resilience into the watershed. Furthermore, we found that flexibility and adaptation are required to avoid command-and-control pathways of resource management. We were able to trace the development of the local fishing association as a response to crisis, followed by the creation of an opportunity for reorganization and the recognition of slow ecosystem structuring variables, and also to define the role of knowledgeable individuals in the whole process. We discuss the key roles of adaptive capacity, institutional learning, and institutional memory for successful ecosystem management and conclude that scientific adaptive management could benefit from a more explicit collaboration with flexible community-based systems of resource management for the implementation of policies as experiments.

Coppice Harvesting of Fuelwood Species on a South African Common: Utilizing Scientific and Indigenous Knowledge in Community Based Natural Resource Management

The limitations of Community Based Natural Resource Management (CBNRM) with respect to the difficulties of comparing local versus scientific knowledge categories within a bounded definition of ‘community’ were investigated by means of a study exploring local indigenous knowledge pertaining to harvesting technique, and the impact of soil and species type on the post-harvest coppice response of popular savanna fuelwood species, among rural inhabitants of the Bushbuckridge region of the Limpopo Province, South Africa. Soils and plants were evaluated chiefly in terms of their perceived ability to retain precipitation, making rainfall a driving force in local understanding of environmental productivity. Some indigenous knowledge showed an agreement with biological data, but overall the variability in responses, as well as the diverse scales at which indigenous and scientific knowledge is directed, were too great to allow for simplistic parallels between local ecological indices to be made. Indigenous environmental knowledge was underscored by the perceived symbolic link between environmental and social degradation. It is recommended that environmental managers incorporate indigenous knowledge as a component of a systems-level approach to natural resource management, where biological, cultural, economic, and symbolic aspects of natural resource use are nested within a broader ecosocial system. This approach to indigenous knowledge is offered as an alternative to the simple scientific evaluation that so often characterizes environmental management.     

Lessons Learned from Reconstructing Interactions Between Local Ecological Knowledge, Fisheries Science, and Fisheries Management in the Commercial Fisheries of Newfoundland and Labrador, Canada

Questions centered on the development of local and traditional ecological knowledge and the relationship of that knowledge to the development of conservation and management practices have recently attracted critical attention. We examine these questions with respect to the dynamic commercial fisheries of the Canadian province of Newfoundland and Labrador. The knowledge of fish harvesters coevolves with fishing practices and is embedded in a dynamic socioecological network that extends into and beyond the fisher, fishery households, and communities to include management, technologies, markets, and marine ecological conditions. Changes in these networks have moved knowledge and practices related to fishing in directions defined by policy, science, economic rationality, and new ecological realities. We characterize this movement as a shift along a continuum from local ecological knowledge (LEK) towards globalized harvesting knowledge (GHK) as harvesters become increasingly disconnected from socioecological relationships associated with traditional species and stocks. We conclude with a discussion of how LEK/GHK have interacted over time and space with other knowledge systems (particularly science) to influence management, and suggest that contingent, empirical evaluations of these interactions will provide a fruitful avenue for future interdisciplinary research.

Access to Land and Water in the Zamfara Reserve. A Case Study for the Management of Common Property Resources in Pastoral Areas of West Africa

In this paper, the link between traditional rights of access to land and water and present day practices is established and illustrated. Data collected during various studies in the Zamfara Forest Reserve, northwest Nigeria, provided information on the different resources utilized (land, pastures, water) and the views and practices of different user-groups and stakeholders. The findings are discussed with a view to improving existing common property resource management (CPRM) in the area.     

Spatial and Social Boundaries and the Paradox of Pastoral Land Tenure: A Case Study from Postsocialist Mongolia

Mobile pastoralists are subject to potentially conflicting needs for secure resource tenure and socially and spatially flexible patterns of resource use. This paradox of pastoral land tenure poses problems for the application of common property theory to the management of pastoral commons. The vagueness, permeability, and overlap of boundaries around pastoral resources and user groups complicate the implementation of formal tenure regimes designed to address insecure pastoral tenures and unsustainable land use patterns. A case-study from postsocialist Mongolia is used to illustrate the problem of spatial and social boundaries for managing pastoral commons. Three solutions to the paradox are evaluated: tenure formalization, rangeland comanagement, and regulation of herders' seasonal movements. An approach that develops and tests institutions to coordinate pastoral movements is recommended over formal tenure for pasturelands, which should be approached with caution in Mongolia.
