Using Domestic Water Analysis to Value Groundwater Recharge in the Hadejia'Jama'are Floodplain, Northern Nigeria
评估了尼日利亚北部哈德贾-贾马雷洪泛区的地下水补给功能价值,该功能受到上游水利计划的威胁。通过分析依赖地下水的家庭用水行为,建立模型估算需求,并计算地下水补给率下降带来的福利变化。
Abstract This article values the groundwater recharge function performed by the Hadejia—Jama'are flood‐plain which is threatened by planned upstream water utilization schemes. Domestic consumption of groundwater resources for households dependent on groundwater resources is analyzed. Three types of households are identified as( i ) those which collect all their water, ( ii ) those which purchase all their water, and ( iii ) those which both collect and purchase water. A behavioral model using a household production function approach is developed to model water demand and a panel formed by pooling contingent behavior and observed data is used to estimate demand. Welfare changes are calculated based on these estimates and on hypothetical reductions in the groundwater recharge rate.
