热带农村地区对生计资源的需求日益增加，导致生物多样性天然林逐步遭到砍伐。恢复被遗弃的农田可以对抗这一进程。然而，由于恢复的目标和模式在生态和社会经济价值方面各不相同，因此，对可实现的生态系统功能和惠益的评估需要进行全面调查。在这里，我们结合联合收割机的结果，从多学科研究的一个独特的评估的基础上正常化的23个生态，经济和社会指标的四个恢复方案在厄瓜多尔的热带安第斯山脉。通过比较本地桤木和外来松树造林、低投入或集约经营的草地恢复和废弃现状的结果表明，造林和集约利用草地都能提高生态价值，但低投入草地不能。经济指标支持植树造林或密集放牧。混血儿和萨拉古罗土著定居者都更倾向于选择植树造林。 废弃农田的恢复具有改善生态系统功能和效益的潜力。使用多学科方法，Knoke等人表明，生态和经济指标有利于在热带安第斯山脉的这些废弃地区植树造林或密集放牧。
Increasing demands for livelihood resources in tropical rural areas have led to progressive clearing of biodiverse natural forests. Restoration of abandoned farmlands could counter this process. However, as aims and modes of restoration differ in their ecological and socio-economic value, the assessment of achievable ecosystem functions and benefits requires holistic investigation. Here we combine the results from multidisciplinary research for a unique assessment based on a normalization of 23 ecological, economic and social indicators for four restoration options in the tropical Andes of Ecuador. A comparison of the outcomes among afforestation with native alder or exotic pine, pasture restoration with either low-input or intense management and the abandoned status quo shows that both variants of afforestation and intense pasture use improve the ecological value, but low-input pasture does not. Economic indicators favour either afforestation or intense pasturing. Both Mestizo and indigenous Saraguro settlers are more inclined to opt for afforestation. Restoration of abandoned farmlands has the potential to improve ecosystem functions and benefits. Using a multidisciplinary approach, Knoke et al. show that ecological and economic indicators favour either afforestation or intense pasturing of these abandoned areas in the tropical Andes.
