摘要

动物水和饲料资源的数量和质量不足是限制埃塞俄比亚畜牧业生产力的主要因素。很常见的是,家庭每天花费相当大的一部分时间来寻找这些稀缺的资源,从而取代了从更有生产力的农业活动和休闲消费中获得的可用劳动时间。本文利用NMBU-MU Tigrai农村家庭调查对518名样本农民进行了调查,研究了寻找动物水和放牧饲料所花费的时间对家庭农业粮食生产和人均粮食消费支出的影响。为了实现我们的目标,我们使用iv2sls来估计人均食品消费支出,并使用双对数来估计粮食产量,这是基于不可分农户模型的。我们的研究结果确实支持了家庭总劳动力投入与作物种植和资源稀缺之间负相关的假设。同样,研究结果证实,减少寻找水的时间可以增加粮食产量、人均粮食消费和粮食安全。此外,对于中位数家庭而言,总体影响表明,寻找水、放牧和收集稻草的时间的减少导致粮食安全的增加。分位数回归的结果进一步证明,这些稀缺资源的影响在整个粮食生产和消费分布中并不均匀。与我们的怀疑一致,收入变量被发现是内生的和工具变量,因为它在统计上显着并且具有预期的迹象。

Implication of Animal Feed and Water Scarcity on Labor Allocation, Food Production and Per Capita Food Consumption in Tigrai Region, Ethiopia
Inadequate quantity and quality of animal water and feed resources are major factors limiting the productivity of livestock farming in Ethiopia. It is common that households spend a considerable share of their daily time to search for theses scarce resources by displacing available labor time away from more productive farming activities and leisure consumption. This paper examines the impact of time spent looking for animal water and grazing feeds on householdsi¯ agricultural food production and per capita food consumption expenditure using NMBU-MU Tigrai Rural Household Survey of 518 sample farmers. To address our objectives, we employ IV 2SLS for estimating per capita food consumption expenditure and double log for estimating food production drawing on non-separable farm household model. Our results do support the hypothesis of a negative relationship between total household labour input to crop farming and resource scarcity. Likewise, the findings confirm that reducing time spent looking for water leads to an increase in food production, per capita food consumption, and food security. In addition for the median household, the total impact revealed that decreasing searching time for water, grazing and collecting time for straw leads to an increment in food security. The results from the quantile regression further proved that the effect of these scarce resources is not uniform across the food production and consumption distribution. In line with our suspicion, the income variable was found to be endogenous and instrumental variables for it were statistically significant and bear the expected signs.
