Abstract

This paper analyses the impact of climate-smart agriculture (CSA) technologies on household dietary diversity and food insufficiency as indicators of food and nutrition security in Kenya. Using a combination of Propensity Score Matching and endogenous treatment effect approaches, we found that adoption of stress-tolerant varieties of several crops (such as bean, pigeon pea, cowpea, maize and sorghum) improved household dietary diversity score by 40% and reduced food insufficiency by 75%. Adoption of improved and resilient livestock breeds (including Red Maasai sheep and Galla goats) improved household dietary diversity by 38% while reducing household food insufficiency by 90%. We also found that stress-tolerant crop varieties were more effective in improving food security outcomes among households with large landholdings and with more educated and younger to middle-age heads. Effects of resilient livestock breeds on household food security were much stronger for households with large landholdings and with young and/or much older heads that have low levels of education. Given the large, demonstrated benefits from the use of the CSA technologies, policies and programs aimed at their promotion should apply appropriate targeting to ensure wider uptake of the technologies and maximum returns on investment.

气候智能型作物品种和牲畜品种对肯尼亚小农粮食安全的影响

本文分析了气候智慧型农业(CSA)技术对肯尼亚家庭膳食多样性和粮食不足的影响，并将其作为粮食和营养安全的指标。采用倾向得分匹配和内源处理效应相结合的方法，我们发现，采用几种作物(如豆类、鸽豆、豇豆、玉米和高粱)的抗逆性品种使家庭膳食多样性得分提高了40%，食物不足减少了75%。采用改良和适应力强的牲畜品种(包括红马赛羊和加拉山羊)使家庭膳食多样性提高了38%，同时使家庭粮食不足减少了90%。我们还发现，在拥有大片土地、受教育程度较高、户主年龄较低的家庭中，耐压作物品种在改善粮食安全结果方面更为有效。对于拥有大片土地、户主年轻和/或年龄较大且受教育程度较低的家庭来说，抗灾牲畜品种对家庭粮食安全的影响要大得多。考虑到使用CSA技术所带来的巨大的、已证明的好处，旨在促进这些技术的政策和方案应采用适当的目标，以确保更广泛地采用这些技术并获得最大的投资回报。

期刊介绍： Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches. Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet. From this perspective, the journal covers the following areas: Global food needs: the mismatch between population and the ability to provide adequate nutrition Global food potential and global food production Natural constraints to satisfying global food needs: § Climate, climate variability, and climate change § Desertification and flooding § Natural disasters § Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production § Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production The sociological contexts of food production, access, quality, and consumption. Nutrition, food quality and food safety. Socio-political factors that impinge on the ability to satisfy global food needs: § Land, agricultural and food policy § International relations and trade § Access to food § Financial policy § Wars and ethnic unrest Research policies and priorities to ensure food security in its various dimensions.
