摘要

目的本文发现了土壤保护实践的回报,并考察了在印度农业中,采用土壤保护实践对福利的影响是否是异质的。设计/方法/方法该研究对第77轮全国抽样调查(2019-21)收集的数据使用内生切换回归(ESR)方法来量化采用土壤保持措施的回报。研究发现,如果农民不实施土壤健康保护措施,他们的作物产量将减少13%。同样,如果没有采用土壤健康管理做法的小农户采用了这些做法,他们的作物产量将增加16%。作者还观察到,采用土壤健康管理做法的回报因农业群体而异,边缘和大型农场往往获得更高的产量。最后,作者发现,无论农场规模如何,不采用土壤健康管理方法的小农户都将从中受益,作物产量将提高29%-31%。研究局限性/含义更多的数据本可以更好地绘制政策含义,因为土壤卡用户的数量相对较少。独创性/价值这项研究工作使用了具有全国代表性的数据,这在这方面是第一次。

Are returns from adoption of soil conservation practices heterogeneous? Evidence from Indian agriculture
PurposeThis paper finds the returns from soil conservation practices and examines whether the welfare implications of adopting the conservation practices are heterogeneous across the farming groups in Indian agriculture.Design/methodology/approachThe study uses an endogenous switching regression (ESR) method on the data collected from the 77th round of National Sample Survey (2019–21) to quantify the returns from adopting soil conservation practices.FindingsIt finds that farmers adopting soil health conservation practices would have reduced their crop yield by 13% if they did not implement them. Similarly, smallholders who have not adopted soil health management practices would have increased crop yield by 16% if they had adopted the practices. The authors also observed that the returns from adopting soil health management practices vary across farming groups, where marginal and large farms tend to gain higher yields. Finally, the authors find that regardless of farm size, smallholders who did not adopt soil health management practices would benefit from adopting these with increased crop yields of 29%–31%.Research limitations/implicationsMore data could have been better for drawing policy implications, since the number of soil card users are relatively less.Originality/valueThis research work uses nationally representative data, which is first in nature on this very aspect.
