Dryland cereals and legumes are important crops in farming systems across the world. Yet they are frequently neglected among the priorities for international agricultural research and development, often due to lack of information on their magnitude and extent. Given what we know about the global distribution of dryland cereals and legumes, what regions should be high priority for research and development to improve livelihoods and food security? This research evaluated the geographic dimensions of these crops and the farming systems where they are found worldwide. The study employed geographic information science and data to assess the key farming systems and regions for these crops. Dryland cereal and legume crops should be given high priority in 18 farming systems worldwide, where their cultivated area comprises more than 160 million ha. These regions include the dryer areas of South Asia, West and East Africa, the Middle East and North Africa, Central America and other parts of Asia. These regions are prone to drought and heat stress, have limiting soil constraints, make up half of the global population and account for 60 percent of the global poor and malnourished. The dryland cereal and legume crops and farming systems merit more research and development attention to improve productivity and address development problems. This project developed an open access dataset and information resource that provides the basis for future analysis of the geographic dimensions of dryland cereals and legumes.
旱地谷物和豆类是全球农业系统中的重要作物。然而,它们在国际农业研究与发展的优先事项中常常被忽视,这通常是由于缺乏关于其规模和范围的信息。鉴于我们对旱地谷物和豆类全球分布的了解,哪些地区应成为改善生计和粮食安全的研发重点?这项研究评估了这些作物的地理范围以及在全球发现它们的农业系统。该研究采用地理信息科学和数据来评估这些作物的关键农业系统和地区。全球18个农业系统应高度重视旱地谷物和豆类作物,其种植面积超过1.6亿公顷。这些地区包括南亚、西非和东非、中东和北非、中美洲以及亚洲其他地区的干旱地区。这些地区容易受到干旱和热应激的影响,土壤条件有限,占全球人口的一半,占全球贫困人口和营养不良人口的60%。旱地谷物和豆类作物以及农业系统值得更多的研发关注,以提高生产力并解决发展问题。该项目开发了一个开放获取的数据集和信息资源,为未来分析旱地谷物和豆类的地理范围提供了基础。
