Abstract

Strategic planning for global agricultural R&D is hampered by a lack of comparable data on target populations. Surprisingly, even the global number of crop-specific farms are unavailable for any given year. We estimate the number of farms growing maize and wheat – the two most important cereals globally – at multiple geographic scales. For 2020, we estimate that a third and a fifth of global farms cultivated maize and wheat respectively. For 2030, we estimate the number of maize farms to increase by 5% (from 216 to 227 million) and wheat farms to decrease by 4% (from 135 to 130 million). Our estimation approach can be extended to other crops, and can contribute to improved agricultural investment programming.

估计全球玉米和小麦农场的数量和分布

由于缺乏关于目标人口的可比数据，妨碍了全球农业研发的战略规划。令人惊讶的是，即使是全球特定作物农场的数量也无法获得任何一年的数据。我们估计了在多个地理尺度上种植玉米和小麦(全球最重要的两种谷物)的农场数量。我们估计，到2020年，全球将分别有三分之一和五分之一的农场种植玉米和小麦。到2030年，我们估计玉米农场数量将增加5%(从2.16亿增加到2.27亿)，小麦农场数量将减少4%(从1.35亿减少到1.3亿)。我们的估算方法可以扩展到其他作物，并有助于改善农业投资规划。

期刊介绍： Global Food Security plays a vital role in addressing food security challenges from local to global levels. To secure food systems, it emphasizes multifaceted actions considering technological, biophysical, institutional, economic, social, and political factors. The goal is to foster food systems that meet nutritional needs, preserve the environment, support livelihoods, tackle climate change, and diminish inequalities. This journal serves as a platform for researchers, policymakers, and practitioners to access and engage with recent, diverse research and perspectives on achieving sustainable food security globally. It aspires to be an internationally recognized resource presenting cutting-edge insights in an accessible manner to a broad audience.
