尽管天然森林提供了许多好处，但随着发展边界的扩大，它们正以不可持续的速度在世界范围内消失。提高天然林养护工作效力的一种办法是，根据对养护政策以及土地利用和土地覆盖变化动态的实地研究，完善地方森林养护政策。为了证明这种方法的力量，这项研究探索了LULC的动态和秘鲁Madre de Dios森林边界的保护政策。这项研究的主要目的是评估指定保护地在迅速扩大的边境景观中的效力，并评估在保护区内授予相互冲突的土地用途指定(如采矿特许权)对生态系统转换的影响。利用统计匹配和基于地理信息系统的土地利用/土地利用变化分析，这项研究表明，2006-2011年期间，与非保护区相比，马德雷德迪奥斯森林边界的指定保护区显著减少了生态系统损失，但不同保护区的影响差异很大。此外，如果存在保护区内相互冲突的土地使用授权，特别是采矿和农业所有权的重叠，则消除了指定土地进行保护的政策附加性。这一发现表明，应避免授权保护区内相互冲突的土地使用权，以确保预期的土地保护结果。这一案例研究还提供了一些例子，说明如何通过详细和频繁地分析土地利用、土地利用和土地利用的变化和养护政策来改进当地的森林保护政策，特别是在土地利用和土地利用的变化和社会经济条件迅速变化的动态前沿地貌中。
Despite the many benefits natural forests provide, they are being lost worldwide at unsustainable rates as development frontiers expand. One approach to improving the efficacy of natural forest conservation efforts is to refine local forest conservation policies based on insights from the place-based study of conservation policies and land-use and land-cover change (LULC) dynamics. To demonstrate the strength of this approach, this research explores the dynamics of LULC and conservation policies on the forest frontier of Madre de Dios, Peru. The main objectives of this research are to evaluate the efficacy of designated conservation lands in a rapidly expanding frontier landscape and to assess the effect on ecosystem conversion of granting conflicting land-use designations, such as mining concessions, inside conservation areas. Using statistical matching and a GIS-based analysis of LULC, this research shows that for the period 2006–2011, designated conservation lands on the forest frontier of Madre de Dios significantly reduced ecosystem losses compared to non-conservation lands, but the effect was highly variable across conservation designations. Also, when present, conflicting land-use authorizations inside conservation areas, specifically overlapping mining and agricultural titles, eliminated the policy additionality of designating lands for conservation. This finding demonstrates that authorizing conflicting land-use rights inside conservation areas should be avoided to ensure intended land conservation outcomes. This case study also provides examples of how local forest conservation policies can be improved through detailed and frequent analyses of LULC and conservation policies, particularly in dynamic frontier landscapes where LULC and socio-economic conditions are rapidly changing.
