Soil and Moisture Management in Mali: A Case Study Analysis for West Africa
研究了马里低资源农民通过提高雨水入渗率和使用化肥来增加收入和粮食产量的潜力,入渗率从40%提升至60%可使可支配收入增加2-4倍。
Abstract In order for farmers to accept improved soil and water management practices, new technologies must be appropriate to the specific site conditions found in the farm setting and be consistent with farmers' objectives and available resources. A whole‐farm modeling analysis of this problem is described. Preliminary estimates of the benefits of increased soil moisture conservation for representative low‐resource farmers in Mali are presented. If farmers could improve rainfall infiltration from currently low rates of about 40% up to 60%, and use small amounts of chemical fertilizers, disposable income could increase two to four times depending on rainfall. Income could be increased another 50% if the infiltration rate was raised to 80%. Food grain production could increase 60 to 90% with improved moisture conservation and fertilizer use.
