The Adoption and Impact of Soil and Water Conservation Technology: An Endogenous Switching Regression Application
研究了非洲农民采用水土保持技术的决定因素及其对作物产量和净收益的影响，基于加纳北部342名稻农的调查数据，发现教育、资本、社会网络等因素显著影响采用决策，且采用该技术显著提高了水稻产量和净收益。
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. <i></i>
