摘要

本文的目的是确定影响埃塞俄比亚西北部农民决定采用两类可持续土地管理(SLM)做法作为气候变化适应战略的因素。基于对734户农户户主数据的分析,采用probit回归模型,通过SLM措施分析农户适应气候变化的决定因素。根据模型结果,对气候变化的认知、适应技术的暴露、教育、对土地退化的认知、坡度、易退化土地、地块数量、作物企业收入、土地规模、农场距离、经济上活跃的家庭规模和农业生态等因素在决定农民使用结构性土地管理实践的决策方面发挥了重要作用。同样,对气候变化的认知、适应环境、耕作经验、坡度、作物企业收入、易退化土地和农业生态在影响农民决定使用非结构性土地管理实践作为适应措施方面也很重要。因此,根据分析的结果,任何促进使用土地管理实践作为适应战略的干预措施都应该考虑到与土地管理实践的性质相关的农业生态特定因素。此外,由于扩大SLM实践作为适应战略是资源密集型的,它需要公共和非公共投资来提供技术支持和提高认识。如果不这样做,将对作物生产力产生不利影响,并加剧农户一级的粮食不安全问题。

Adapting Smallholder Agriculture to Climate Change through Sustainable Land Management Practices: Empirical Evidence from North-West Ethiopia
The objective of this paper was to determine the factors that influence farmers’ decision to use two categories of sustainable land management (SLM) practices as adaptation strategy to climate change in the North-West Ethiopia. It was based on analysis of data collected from 734 farm household heads and employed probit regression model to analyze the determinants of adaptation to climate change through SLM measures. Based on the model result, factors, like perception of climate change, exposure to adaptation techniques, education, perception of land degradation, slope, land prone to degradation, number of parcels, crop enterprise income, land size, farm distance, economically active family size and agro-ecology are found important in determining farmers’ decision to use structural land management practices. Likewise, perception of climate change, exposure to adaptation, farming experience, slope, crop enterprise income, land prone to degradation and agro-ecology are found important in affecting farmers’ decision to use non-structural land management practices as adaptation measure. Therefore, in line with the findings of the analysis, any intervention that promotes use of land management practices as adaptation strategy should take into account agro-ecology specific factors that are relevant to the nature of the land management practices. Moreover, since scaling up of SLM practices as adaptation strategy is resource intensive, it requires both public and non-public investment for providing technological support and raising awareness. Failure to do so would adversely affect crop productivity and exacerbate food insecurity problems at farm household level.
