In the late 1980s there were two campaigns to save African elephants. One banned international trade in ivory. The other established common property rights to elephants for local communities. Has either campaign saved the elephants? To answer this question, we constructed and solved two models, a biomass model and an age structured model. We conclude that in countries which successfully establish property rights, local communities will conserve elephants.
Coral reefs are at risk from many threats including global warming causing coral bleaching, over fishing or destructive fishing, pollution by sediments, nutrients and toxic chemicals, coral mining and shoreline development and unregulated tourism. Marine Protected Areas (MPAs) are an important tool for marine conservation and management. This book provides practical advice on how to design and implement ecological and socio-economic monitoring programmes aimed at addressing these issues.
This report brings together 27 indicators of human and ecosystem wellbeing using IUCN's pioneering Sustainability Assessment method. It is intended to complement Wellbeing Scores software, which allows users to explore different standards and combinations of what comprises sustainable development. The publication may provoke debate amongst forest conservationists and critics and provide them with a platform for exploring this new software.
This report is on the first national conference on CBNRM that was a culmination of a series of three workshops on key topics in CBNRM, namely: community mobilization, enterprise development and natural resource monitoring and management. The objectives of the conference were to reflect on the progress made so far in implementing CBNRM activities, to consider the recommendations from the workshops and to deliberate the way forward.
Outlines approaches to assessment of the status and sustainability of national biodiversity. Methods are introduced for biodiversity survey, assessment of the status of species and habitats, and identification of local users of biological resources and the importance and impacts of such use.
"Sustainability" and "sustainable development" have become the guiding principles of environmental policy and international development, but what do they really mean? How do we know if we are moving toward a sustainable world? The contributors to this volume address these questions from diverse backgrounds and a variety of perspectives - with the aim of translating ideas into practice.
