Abstract

This paper introduces a special feature on biodiversity conservation and poverty traps. We define and explain the core concepts and then identify four distinct classes of mechanisms that define important interlinkages between biodiversity and poverty. The multiplicity of candidate mechanisms underscores a major challenge in designing policy appropriate across settings. This framework is then used to introduce the ensuing set of papers, which empirically explore these various mechanisms linking poverty traps and biodiversity conservation.

*Important exceptions offering integrative modeling approaches include those described by Dasgupta (4) and by Carpenter and Brock (5).
These concepts are developed with greater detail and precision by Dasgupta (8).
