Abstract

In this paper, we investigate the agronomic and economic impact of cultivating seeds of improved bean varieties by smallholder farming households in Rwanda. The improved bean varieties under investigation are conventionally-bred, iron biofortified bush and climbing bean varieties, developed for high yield, climate resilience, and increased bioavailable iron content compared to commonly consumed varieties. Seeds of these varieties were delivered to 383,000 farmers across Rwanda by the time we implemented nationally representative survey of bean farmers in 2015 season B. Our findings indicate that growing the seeds of these improved bean varieties, compared to the bean planting materials used by farmers at the time, significantly enhances farmers’ yield and income. The yield increases amount to 153 kg/ha (23%) for growers of improved bush bean seeds and 182 kg/ha (20%) for growers of improved climbing bean seed, while the income increases amounts to $84/ha (27%) for improved bush bean seed growers and $110/ha (23%) for improved iron climbing bean growers, on average. These results bolster public policies and private sector efforts that aim to expand access to improved seeds in Rwanda and other African countries.

在卢旺达实现繁荣：高产生物强化豆种对农民产量和收入的影响

在本文中，我们调查了卢旺达小农户种植改良豆类品种种子对农艺和经济的影响。所调查的改良豆类品种是传统培育的铁生物强化灌木豆和攀援豆品种，与普通豆类品种相比，这些品种产量高、气候适应性强、生物可利用的铁含量更高。我们的研究结果表明，与农民当时使用的豆类种植材料相比，种植这些改良豆类品种的种子可显著提高农民的产量和收入。改良灌木豆种子的种植者每公顷增产 153 公斤（23%），改良攀缘豆种子的种植者每公顷增产 182 公斤（20%）；改良灌木豆种子的种植者每公顷平均增收 84 美元（27%），改良铁攀缘豆的种植者每公顷平均增收 110 美元（23%）。这些结果支持了旨在扩大卢旺达和其他非洲国家获得改良种子机会的公共政策和私营部门的努力。

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.
