Perceived profitability is a key factor in explaining farmers' decision to adopt or not adopt sustainable land management (SLM) technologies. Despite this importance, relatively little is known about the economics of SLM. This paper contributes to the literature by analysing data on costs and perceived cost/benefit ratios of SLM technologies. Data are taken from the World Overview of Conservation Approaches and Technologies technology database and cover 363 case studies conducted in a variety of countries between 1990 and 2012. Based on an in-depth descriptive analysis, we determine what costs accrue to local stakeholders and assess perceived short-term and long-term cost/benefit ratios. Our results show that a large majority of the technologies in our sample are perceived as being profitable: 73% were perceived to have a positive or at least neutral cost/benefit ratio in the short term, while 97% were perceived to have a positive or very positive cost/benefit ratio in the long term. An additional empirical analysis confirms that economic factors are key determinants of land users' decisions to adopt or not adopt SLM technologies. We conclude that a wide range of existing SLM practices generate considerable benefits not only for land users, but for other stakeholders as well. High initial investment costs associated with some practices may, however, constitute a barrier to their adoption; short-term support for land users can help to promote these practices where appropriate.

可持续土地管理技术的经济效益和成本:对 WOCAT 全球数据的分析

感知盈利能力是解释农民决定采用或不采用可持续土地管理 (SLM) 技术的关键因素。尽管如此重要,但人们对 SLM 的经济学知之甚少。本文通过分析有关 SLM 技术的成本和感知成本/收益比的数据为文献做出贡献。数据取自 World Overview of Conservation Approaches and Technologies 技术数据库,涵盖 1990 年至 2012 年间在不同国家进行的 363 个案例研究。基于深入的描述性分析,我们确定当地利益相关者会产生哪些成本并评估感知到的成本短期和长期成本/收益比率。我们的结果表明,我们样本中的大部分技术都被认为是有利可图的:73% 的人认为短期内成本/收益比为正或至少为中性,而 97% 的人认为长期成本/收益比为正或非常正。另一项实证分析证实,经济因素是土地使用者决定采用或不采用可持续土地管理技术的关键决定因素。我们得出的结论是,广泛的现有可持续土地管理实践不仅为土地使用者,而且为其他利益相关者带来了可观的利益。然而,与某些做法相关的高昂初始投资成本可能会成为采用这些做法的障碍;对土地使用者的短期支持有助于在适当情况下促进这些做法。另一项实证分析证实,经济因素是土地使用者决定采用或不采用可持续土地管理技术的关键决定因素。我们得出的结论是,广泛的现有可持续土地管理实践不仅为土地使用者,而且为其他利益相关者带来了可观的利益。然而,与某些做法相关的高昂初始投资成本可能会成为采用这些做法的障碍;对土地使用者的短期支持有助于在适当情况下促进这些做法。另一项实证分析证实,经济因素是土地使用者决定采用或不采用可持续土地管理技术的关键决定因素。我们得出的结论是,广泛的现有可持续土地管理实践不仅为土地使用者,而且为其他利益相关者带来了可观的利益。然而,与某些做法相关的高昂初始投资成本可能会成为采用这些做法的障碍;对土地使用者的短期支持有助于在适当情况下促进这些做法。然而,这对它们的采用构成了障碍;对土地使用者的短期支持有助于在适当情况下促进这些做法。然而,这对它们的采用构成了障碍;对土地使用者的短期支持有助于在适当情况下促进这些做法。
