Degradation is limiting the ability of arid lands to provide ecosystem services. Agroforestry Systems can supply several of these ecosystem services. In this context, we carried out a systematic review of literature, to find the ecosystem services provided by Agroforestry Systems in arid lands irrigated by rainwater harvesting systems in worldwide. The ecosystem services most mentioned (soil quality, productivity increase, carbon sequestration, biodiversity conservation, cultural values, water regulation and purification, and pollination), that were provided by the four Agroforestry Systems (protein banks, intercropping, windbreaks and homegardens) were used to apply the Weight of Evidence Approach. The regions where Agroforestry Systems practices were carried out, the species most used and their multipurpose were also evaluated. Most of the experiences were documented in Africa (42%) and Asia (37%). We registered 82 species, being the Fabaceae and Chenopodiaceae families were the most used. These species (49% shrubs) were mainly integrated in Agroforestry Systems by homegardens (43%), intercropping (40%), and windbreaks (23%). The most evaluated species uses were medicine (58%), food (28%), and forage (27%). We found several positive evidence of Agroforestry Systems in all ecosystem services evaluated. We also found some evidence that Agroforestry Systems can cause drawbacks such as salinization, or species invasion.

退化限制了干旱土地提供生态系统服务的能力。农林业系统可以提供其中一些生态系统服务。在此背景下，我们对文献进行了系统回顾，以发现农林业系统在全球雨水收集系统灌溉的干旱土地上提供的生态系统服务。使用了四个农林业系统（蛋白质库、间作、防风林和家庭花园）提供的最受提及的生态系统服务（土壤质量、生产力提高、碳固存、生物多样性保护、文化价值、水调节和净化以及授粉）应用证据权重法。还对开展农林业系统实践的地区、最常用的物种及其多用途进行了评估。大多数经验记录在非洲（42%）和亚洲（37%）。我们登记了 82 个物种，其中豆科和藜科是使用最多的。这些物种（49% 灌木）主要通过家庭花园（43%）、间作（40%）和防风林（23%）融入农林业系统。评估最多的物种用途是医药（58%）、食品（28%）和饲料（27%）。我们在所有评估的生态系统服务中发现了农林业系统的一些积极证据。我们还发现一些证据表明农林业系统可能会导致盐碱化或物种入侵等缺点。
