Abstract

The promotion of climate-resilient practices (CRPs) requires the development of the capacity of farmers to adopt these practices owing to the knowledge-intensive nature of technologies. Extension services serve as a conduit for facilitating the conceptualization of CRPs and are instrumental in improving the resiliency and mitigation of climate change. We used a social-ecological framework and a multivariate probit model to analyze the drivers of the CRP uptake in moisture-stressed areas in Ethiopia, with a particular focus on extension services. Unlike previous studies that investigated a single technology, we considered a bundle of technologies. We focused on the use of two capital-intensive CRPs (drought-resistant seed and inorganic fertilizer) and four knowledge-intensive CRPs (minimum tillage, farmyard manure, water-saving technology, and crop residue retention). The role of extension services in promoting other CRPs beyond input and capital-intensive technologies was insignificant. Heterogeneity analysis revealed that the correlation between extension services and the adoption of other knowledge-intensive natural resource management practices holds irrespective of the proximity to the extension service providers. This finding highlights the need for targeted and tailored interventions that support farmers to address the challenges faced by them in moisture-stressed areas. Accordingly, we propose continuously improving the ability of the extension service providers to promote climate-change adaptation knowledge and practices. This should be accompanied by efforts to strengthen a pluralistic extension system, improve land tenure security, and decrease transaction costs for farmers through output market linkages.

推广服务对采用气候智能型高粱生产方法的影响:埃塞俄比亚旱地的启示
由于技术具有知识密集型的特点,推广具有气候抗御能力的做法(CRPs)需要发展农民采用这些做法的能力。推广服务是促进 "抵御气候变化实践 "概念化的渠道,有助于提高抵御和减缓气候变化的能力。我们采用社会生态框架和多元 probit 模型分析了埃塞俄比亚湿度胁迫地区吸收 CRP 的驱动因素,尤其关注推广服务。与以往调查单一技术的研究不同,我们考虑的是一揽子技术。我们重点研究了两项资本密集型 CRP(抗旱种子和无机肥)和四项知识密集型 CRP(最小耕作、农家肥、节水技术和作物残留)的使用情况。除投入和资本密集型技术外,推广服务在促进其他 CRP 方面的作用并不显著。异质性分析表明,推广服务与采用其他知识密集型自然资源管理方法之间存在相关性,而与推广服务提供者的距离远近无关。这一发现突出表明,有必要采取有针对性和量身定制的干预措施,支持农民应对湿气胁迫地区所面临的挑战。因此,我们建议不断提高推广服务提供者推广气候变化适应知识和做法的能力。与此同时,还应努力加强多元化的推广体系,改善土地使用权保障,并通过产出市场联系降低农民的交易成本。
