Abstract

This paper examines the effectiveness of foreign aid in the agricultural sector in the presence of climate variability. Climate variability, measured by fluctuations in temperature and precipitation rates, can disrupt production and, in particular, lower agricultural productivity and access to food. On the other hand, foreign aid in agriculture is targeted towards low- and middle-income countries to increase people's welfare and strengthen governments' development goals. Using data from 53 countries during 1990–2019, this study examines the effect of different types of agricultural aid on agricultural labour productivity in the presence of climate change shocks. In particular, four distinct channels of agricultural aid are considered, viz. Education, R&D, Policy, and Services. We find that R&D aid is the most effective channel in mitigating the adverse effects of climate variability. These results are robust to endogeneity biases and alternative estimation techniques. Findings from this study have substantial policy implications, as we show that aid effectively mitigates the impacts of climate change and presents sustainable growth opportunities for poor and developing countries.

外国援助能否减轻气候变化对农业的影响？来自中低收入国家的证据

本文考察了在气候变化的情况下，农业部门对外援助的有效性。以温度和降水率的波动来衡量的气候变率可能破坏生产，特别是降低农业生产力和粮食获取。另一方面，农业外援的目标是中低收入国家，以增加人民福利和加强政府的发展目标。本研究利用1990年至2019年53个国家的数据，考察了在气候变化冲击存在的情况下，不同类型的农业援助对农业劳动生产率的影响。特别地，我们考虑了四种不同的农业援助渠道，即教育、研发、政策和服务。研究发现，研发援助是缓解气候变率不利影响的最有效渠道。这些结果对内生性偏差和替代估计技术是稳健的。这项研究的结果具有重大的政策意义，因为我们表明，援助有效地减轻了气候变化的影响，并为贫穷和发展中国家提供了可持续增长的机会。

期刊介绍： Ecological Economics is concerned with extending and integrating the understanding of the interfaces and interplay between "nature''s household" (ecosystems) and "humanity''s household" (the economy). Ecological economics is an interdisciplinary field defined by a set of concrete problems or challenges related to governing economic activity in a way that promotes human well-being, sustainability, and justice. The journal thus emphasizes critical work that draws on and integrates elements of ecological science, economics, and the analysis of values, behaviors, cultural practices, institutional structures, and societal dynamics. The journal is transdisciplinary in spirit and methodologically open, drawing on the insights offered by a variety of intellectual traditions, and appealing to a diverse readership. Specific research areas covered include: valuation of natural resources, sustainable agriculture and development, ecologically integrated technology, integrated ecologic-economic modelling at scales from local to regional to global, implications of thermodynamics for economics and ecology, renewable resource management and conservation, critical assessments of the basic assumptions underlying current economic and ecological paradigms and the implications of alternative assumptions, economic and ecological consequences of genetically engineered organisms, and gene pool inventory and management, alternative principles for valuing natural wealth, integrating natural resources and environmental services into national income and wealth accounts, methods of implementing efficient environmental policies, case studies of economic-ecologic conflict or harmony, etc. New issues in this area are rapidly emerging and will find a ready forum in Ecological Economics.
