Sustainability interventions on agro-ecosystems: An experience from Yunnan Province, China

Abstract

Increasing agricultural production, without having a pronounced negative impact on ecosystems, continues to be a massive challenge. Interventions in sustainability that improve agro-ecosystems are thus crucial. Current literature focuses on sustainability concepts, assessment tools, and intervention impacts, yet lacks in intervention mechanisms and implementation processes. Therefore, this study aims to present an intervention framework on agro-ecosystems that helps transform sustainability concepts into implementation actions. We first create the intervention framework on agro-ecosystems using a systematic approach, and then analyze the intervention mechanism. Next, we formulate the agro-ecological sustainability index (AESI) and its sub-indices to assess the results of interventions. We find that, by integrating interventions, we can reverse the sustainability trend from deterioration to recovery and improvement; however, with a spatial difference. We highlight that the process for a successful intervention comprises (1) utilizing an integrated intervention portfolio, (2) acting with a long-term perspective, (3) utilizing adaptive implementation, and (4) strengthening local institutions. We suggest closely monitoring the impact of interventions, diversifying farmers’ income sources, and enhancing capacity building for young generations. Additionally, we suggest conducting multidisciplinary research and strengthening local government capacity to hedge against future risks. Our intervention framework and Yunnan’s intervention experience provides a useful lesson for other policymakers and researchers to achieve the Sustainable Development Goals.
