Abstract

Declining agricultural productivity, land clearance and climate change are compounding the vulnerability of already marginal rural populations in West Africa. 'Farmer-Managed Natural Regeneration' (FMNR) is an approach to arable land restoration and reforestation that seeks to reconcile sustained food production, conservation of soils, and protection of biodiversity. It involves selecting and protecting the most vigorous stems regrowing from live stumps of felled trees, pruning off all other stems, and pollarding the chosen stems to grow into straight trunks. Despite widespread enthusiasm and application of FMNR by environmental management and development projects, to date, no research has provided a measure of the aggregate livelihood impact of community adoption of FMNR. This paper places FMNR in the context of other agroforestry initiatives, then seeks to quantify the value of livelihood outcomes of FMNR. We review published and unpublished evidence about the impacts of FMNR, and present a new case study that addresses gaps in the evidence-base. The case study focuses on a FMNR project in the district of Talensi in the semi-arid Upper East Region in Ghana. The case study employs a social return on investment analysis, which identifies proxy financial values for non-economic as well as economic benefits. The results demonstrate income and agricultural benefits, but also show that asset creation, increased consumption of wild resources, health improvements, and psycho-social benefits created more value in FMNR-adopting households during the period of the study than increases in income and agricultural yields.

摘要

农业生产力下降、土地开垦和气候变化正使西非本就处于边缘的农村人口更加脆弱。“农民自主自然再生”(FMNR)是一种耕地恢复和重新造林的方法,旨在协调持续的粮食生产、土壤保护和生物多样性保护。它包括选择和保护从砍伐树木的活树桩上重新生长出来的最健壮的茎干,修剪掉所有其他茎干,并对选定的茎干进行截干处理,使其长成笔直的树干。尽管环境管理和发展项目对FMNR普遍热情高涨并加以应用,但迄今为止,尚无研究衡量社区采用FMNR对总体生计的影响。本文将FMNR置于其他农林业举措的背景下,进而试图量化FMNR带来的生计成果的价值。我们回顾了已发表和未发表的关于FMNR影响的证据,并呈现了一个新的案例研究,以填补证据基础方面的空白。该案例研究聚焦于加纳半干旱的上东部地区塔伦西 district的一个FMNR项目。该案例研究采用了社会投资回报分析,确定了非经济和经济收益的替代财务价值。结果表明了收入和农业方面的益处,但也显示出在研究期间,资产创造、野生资源消费增加、健康改善以及心理社会效益在采用FMNR的家庭中创造的价值超过了收入和农业产量的增加。
