本文确定了影响非洲农民决定采用水土保持技术的因素，以及这种技术如何影响农业产量和净收益。这项技术很重要，因为它提高了雨水的利用效率，这是缺水的撒哈拉以南非洲地区的一个关键问题。对加纳北方342位稻农调查的新数据分析表明，农民的教育程度、资金和劳动力约束、社交网络和推广联系以及农场土壤条件主要决定了田间起垄的采用，采用这项技术可以显著提高水稻产量和净收益。
This paper identifies the factors that affect farmers' decisions to adopt soil and water conservation technology in Africa and how this technology impacts farm yields and net returns. This technology is important because it improves efficiency of water use from rainfall a critical issue in water-deficient Sub-Saharan Africa. An analysis of new data from a survey of 342 rice farmers in northern Ghana shows that farmers' education, capital and labor constraints, social networks and extension contacts, and farm soil conditions mainly determine adoption of field ridging, and the adoption of this technology increases rice yields and net returns significantly.
