A vast number of people in developing countries depend on the natural environment for their livelihoods on farmland or forests, wetlands or coastal areas. For these people, the environment is much more than a source of recreation it is the basis of the economy. But poorly functioning markets, incomplete property rights, and misguided policies can drive peoples behaviour in ways that are rational in the short term or from an individuals point of view, but harmful to the environment and future generations. Economics has much to offer in understanding and influencing this behaviour. It also provides tools for decision-makers faced with difficult choices. How can we compare the value of environmental benefits to the costs of safeguarding them? How can we assess the impacts of environmental action (or inaction) on the poor? How should we share the costs of improvements? This book shows how researchers from four of IDRCs regional environmental economics networks have dealt with questions like these in a wide variety of situations in Asia, Africa, and Latin America. It brings together insights from more than 15 years of research and assesses their impact on policy and the research community. It concludes by looking at the future of environmental economics in the developing regions of the world.David Glover leads the Environmental Economics program at Canadas International Development Research Centre.
