In this project, variation and patterns in mobile phone access are investigated and the effect of mobile phone access on global food security over the last 20 years is assessed. Policy initiatives have proliferated under the assumption that mobile phones have the ability to foster improvements in development sectors, particularly in subsistence agriculture (by, for example, allowing farmers to check weather forecasts). However, there has been little cross-national empirical research investigating whether mobile phones in aggregate contribute to development outcomes. If mobile phones contribute to agrarian sector development in the way that policy narratives and case studies suggest, their distribution should have positive impacts on global food security across-countries and over time. Findings from this study will contribute to public welfare and security by testing the assumption underlying the promise of mobile phones as a development tool. Building on case study findings that find support for the economic, political, health, and educational benefits of access to newer information and communication technologies, this project uses a quantitative cross-national comparative research design to explain patterns of mobile phone distribution and access. It subsequently assesses the role of the distribution of mobile phone access in contributing to one central development outcome, food security. Data come from the International Telecommunications Union, supplemented with data from other sources. These data are analyzed using appropriate statistical methods.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在这个项目中，调查了移动电话接入的变化和模式，并评估了过去20年移动电话接入对全球粮食安全的影响。假设移动电话有能力促进发展部门的改进，特别是自给自足的农业(例如，通过允许农民查看天气预报)，政策倡议激增。然而，很少有跨国的实证研究调查移动电话总体上是否有助于发展成果。如果移动电话以政策说明和案例研究所表明的方式促进农业部门的发展，那么随着时间的推移，移动电话的分布应该会对各国的全球粮食安全产生积极影响。这项研究的结果将通过测试手机作为发展工具的承诺背后的假设，为公共福利和安全做出贡献。在案例研究结果的基础上，该项目使用量化的跨国比较研究设计来解释移动电话的分布和获取的模式。报告随后评估了移动电话接入的分布在促进一个核心发展成果--粮食安全--方面的作用。数据来自国际电信联盟，并辅之以其他来源的数据。这些数据使用适当的统计方法进行了分析。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
