This paper assessed the impact of soil and water conservation practices on farm productivity and risk exposure using data from 1204 plots in the semiarid tropics of India. A probit model was used to assess the determinants of adoption of soil bunds. We employed a moment-based approach for estimating crop revenue, its variability and downside risk exposure, i.e., crop failure. Furthermore, we also used a doubly robust method for assessing the impact of soil bunds on crop revenue, its variability and downside risk. Matching and propensity-based methods were also used to check robustness. The results show that training, access to credit and extension services are key determinants of adoption of soil bunds. Furthermore, the results also suggest that soil bunds not only improve the crop revenue but also reduce its variability. Most interestingly, we show that soil bunds also reduce the chances of downside risk, i.e., crop failure. Therefore, in view of increasing climate change and variability in the semiarid tropics, it can be suggested that soil bunds could be an important adaptation strategy for improving productivity and reducing risk exposure. This paper supports the investment in soil and water conservation technologies for sustaining the livelihood of resource-poor farmers of ecologically fragile regions such as the semiarid tropics.

There is a growing concern about the sustainability of agriculture due to the indiscriminate use of chemical fertilizers in several parts of the world. In India, the Indo-Gangetic Plain (IGP) is a region where the externalities of excessive use of chemical fertilizers for cereal production manifest in groundwater pollution, air pollution due to emissions, and soil degradation. In this context, we study the adoption of organic fertilizers in the region and the determining factors. We use data collected from 400 rice farmers to empirically test the link between farmers’ perceptions, revenue expectations, socioeconomic factors, and the policy environment to adopt organic fertilizers. We use Tobit and Cragg’s double hurdle model to study the farmers’ expenditure and adoption of organic fertilizers, respectively. The results show that only 32% of the farmers adopted organic fertilizers in the region. Further, membership in farmer organizations, training, and education are the key variables that determine the adoption of organic fertilizers, in addition to a positive perception of the benefits of their usage. The findings highlight the need for efficient extension efforts in organic fertilizers and suggest policy interventions that promote collective learning through farmer groups.
