Forest landscape restoration through agroforestry has been implemented as a Nature-based Solution to deforestation in the Global South with varied outcomes. The Modified Taungya System (MTS) is one of such programmes introduced in Ghana to address socio-economically-induced degradation of forest reserves. For two decades since its establishment, there has not been any examination of a synthesised findings on the MTS and their implication for the prospects of the programme. Using the PRISMA method to select empirical studies, this article examines the state of reforestation under the MTS by reflecting on the conditions of success and failures of the programme. In doing so, two interrelated arguments are advanced. First, the MTS seems to be successful when farmers are well-educated about the programme and their future benefits in the reserves that they enrich. Second, the MTS has largely failed to achieve its full potentials for forest recovery due to bribery, corruption and nepotism that have bedevilled land demarcation to, and delays in signing benefit sharing agreement with, farmers. There is a need for a thorough sensitisation on the MTS to enhance its transparency. Besides, the MTS needs to be remodified if it would be one of the strategies to contribute to the Bonn Challenge and for a durable climate mitigation.

通过农林业恢复森林景观已被作为一种基于自然的解决方案来实施，以解决全球南方的森林砍伐问题，并取得了不同的结果。改良 Taungya 系统 (MTS) 是加纳推出的此类计划之一，旨在解决社会经济引起的森林保护区退化问题。自建立以来的二十年里，尚未对 MTS 的综合调查结果及其对该计划前景的影响进行过任何审查。本文采用 PRISMA 方法选择实证研究，通过反思该计划的成功和失败的条件来考察 MTS 下的重新造林状况。在此过程中，提出了两个相互关联的论点。首先，当农民充分了解该计划以及他们在丰富的储备中获得的未来利益时，MTS 似乎会取得成功。其次，由于贿赂、腐败和裙带关系，MTS在很大程度上未能充分发挥森林恢复的潜力，这些问题困扰着农民的土地划界和与农民签署利益分享协议的拖延。需要对多边贸易体系进行彻底的宣传，以提高其透明度。此外，如果多边贸易体系是为波恩挑战和持久气候减缓做出贡献的战略之一，则需要对其进行重新修改。
