Modeling Ecological Constraints on Tropical Forest Management: Spatial Interdependence, Irreversibility, and Uncertainty
构建了一个空间-时间经济模型,纳入生态约束如地块间相互作用和不可逆性,发现最优森林面积大于传统模型,并探讨了可持续性、森林破碎化等问题。
This paper presents a stylized spatial–intertemporal model for the economic management of tropical forests, a model that reflects ecological constraints, especially spatial interactions across plots and the irreversibility of some uses. The explicit recognition of the varied uses of forested land, spatial interdependence, irreversibility, and uncertainty leads to optimal patterns that have different structures and, in general, more forested area than those recommended by traditional models. Two “flexible” land uses and one spatial interaction term contribute to the quasi-option value. The spatial–intertemporal framework permits examination of important issues such as sustainability, forest fragmentation, and land recovery dynamics.
