Agroforestry-based sustainable land management (SLM) interventions provide opportunities for tackling land degradation and its associated socio-economic issues. Agroforestry is not a guaranteed SLM fix as every agroforestry practice is not automatically relevant to each context. It is critical to identify key considerations for ensuring a good fit between agroforestry and the receiving environment. This study identifies and analyses key factors for assessing the context-specific suitability of an agroforestry practice for SLM using a case-study of homegarden agroforestry in a degraded catchment. An analysis of biophysical and socio-economic characteristics of the catchment covering land degradation, SLM aspirations of residents, agriculture and agroforestry activities was conducted through literature review, field observations, GIS and remote sensing, stakeholder engagement and a questionnaire survey. Considerations in agroforestry practice assessment for SLM include agricultural and SLM objectives, which at our study site were increased crop production and arresting soil erosion. Availability of requisite resources, namely land, water and fencing; stakeholder interest in the tree and/or crop planting, species of interest and suitability of the species for the biophysical conditions should also be assessed. We propose a framework for systematically working through the relevant factors and assessing the suitability of an agroforestry practice for SLM intervention in a specific context. Based on the framework, homegarden agroforestry is an appropriate SLM intervention as it could meet stakeholders' SLM and agricultural objectives. Identification and systematic assessment of relevant factors are critical for ensuring the acceptability of agroforestry practice in a locality and the sustainability of associated SLM interventions.

评估家庭花园农林业对南非退化景观的可持续土地管理干预

基于农林业的可持续土地管理 (SLM) 干预措施为解决土地退化及其相关的社会经济问题提供了机会。农林业并不是一个有保证的 SLM 解决方案，因为每个农林业实践都不会自动与每个环境相关。确定关键考虑因素以确保农林业与接收环境之间的良好匹配至关重要。本研究使用退化集水区的家庭花园农林业案例研究，确定并分析了评估农林业实践对 SLM 的特定环境适用性的关键因素。通过文献回顾、实地观察、GIS 和遥感、利益相关者参与和问卷调查。SLM 农林业实践评估的考虑因素包括农业和 SLM 目标，在我们的研究地点，这些目标是增加作物产量和阻止土壤侵蚀。必要资源的可用性，即土地、水和围栏；还应评估利益相关者对树木和/或作物种植的兴趣、感兴趣的物种以及该物种对生物物理条件的适用性。我们提出了一个框架，用于系统地研究相关因素并评估农林业实践在特定背景下对 SLM 干预的适用性。基于该框架，家庭花园农林业是一种适当的 SLM 干预措施，因为它可以满足利益相关者的 SLM 和农业目标。
