Spatial Modeling of Extraction and Enforcement in LDC Protected Areas

چکیده

Conflicts between resource-dependent people and protected area managers abound in many developing countries. From the rural people's perspective, protected areas may contain valuable or necessary natural resources that are worth the effort, and risk of capture, to extract. From the protected area manager's perspective, the rural people's extraction of resources causes environmental degradation and is illegal. Protected area managers attempt to enforce the regulations against such extraction but, due to serious budget constraints, cannot deter all extraction. Because the rural people's marginal net benefit from extraction is a function of the distance from their village, the protected area managers have an opportunity to allocate their enforcement effort in a spatial pattern that reduces that marginal benefit and minimizes the resource degradation for a given budget level. This paper develops a spatial model that determines the protected area manager's optimal enforcement pattern and the rural people's optimal extraction pattern under that enforcement pattern. The results reveal the inefficiency of many protected area policies that maintain constant levels of enforcement throughout the protected area. The results also lend support to explicitly spatial management schemes such as buffer zones.
