Zero tillage (ZT) for wheat is one of the most widely adopted resource-conserving technologies in the rice-wheat systems in northern India. In areas of Haryana with rice-wheat systems, 36.5 percent of all farmers practice ZT on 35 percent of their wheat area. Yet the literature measuring the impact of ZT on farmers’ fields is scarce. This study fills this gap by using the data collected from a random sample of 717 farmers from 50 villages in 10 districts of Haryana. It applies the difference-in-differences method to five-year recall data on wheat yields in ZT and conventionally tilled plots of land to quantify the crop loss due to unseasonal rains right before wheat harvests in March 2015. The results reveal significantly lower wheat yield losses in the ZT plots than in the conventionally tilled plots. On average, farmers suffered yield losses ranging between 3.73 and 4.53 quintals per hectare in 2015 due to unseasonal rains. The loss was lower by 1.05–1.10 quintals per hectare in ZT plots. The analysis clearly shows that adoption of ZT helped in reducing crop loss in wheat by 24–28 percent, valued at 1,523–1,595 Indian rupees (Rs.) per hectare (approximately US$22.50 per hectare). The loss avoided due to ZT is nearly equal to the prevailing rental rate of the ZT machine (Rs. 1,500 per hectare) in Haryana. Climate models suggest that the incidence of short-duration acute hydro meteorological events is likely to increase in years to come. Such events are hard to predict and prepare for, and dealing with them hinges mainly on disaster relief. However, our results show that adoption of ZT is one possible way to reduce potential loss from some of these weather events and that ZT is therefore well characterized as a climate-smart technology.

The paper estimates the impacts of risk-reducing government programs on the use of conservation tillage (no-till and other conservation tillage) practices in agriculture. Conservation tillage can be used to reduce production risk from weather shocks. However, subsidized crop insurance and disaster payments also reduce risk through financial assistance. The paper examines the extent to which risk-reducing tillage practices and government programs are substitutes for each other. The economic model shows that a decline in average weather conditions increases the use of conservation tillage. The economic model also shows that the impact of weather risk and risk aversion on risk-reducing practices like conservation tillage are ambiguous. The effect depends on the degree that losses are offset by government payments. The paper uses county-level tillage practice data from the Conservation Tillage Information Center for the three-state region of Iowa, Nebraska, and South Dakota. Results are estimated using instrumental variables and spatial panel data techniques. Instruments for the program participation and payment data include political variables and weather data. The empirical analysis shows that recent disaster and indemnity payments are associated with an increase in the use of no-till and a decrease in the use of other conservation till. Results also show that producers in counties with recent drought and flood events are more likely to use other conservation tillage. The results imply that there may be unintended impacts of changes to agricultural policies like disaster payments and crop insurance on the use of on-farm conservation practices.

Gold mining is the main economic activity in Madre de Dios, Peru. Despite efforts, the state has not yet managed to identify a formalization process achievable for small operators. In addition, many small-scale miners are driven by poverty and need income to provide for their basic needs. Because participation in small-scale mining is largely driven by poverty, it is likely that, in the longer term, much artisanal mining activity will disappear naturally if, through economic development, more attractive work options become available. This paper reviews the importance of illegal mining in Madre de Dios and the potential for development of the agriculture sector. It also analyzes three different policy scenarios: (1) government spending to rectify the environmental damage in the region caused by illegal mining, (2) development of the agricultural sector in the region, and (3) a final scenario with both environmental restoration and agricultural development. Results show that additional government spending in Madre de Dios does not significantly affect the rest of the country and that investment in agriculture can achieve structural change in the gross domestic product of Madre de Dios. Development of the agricultural sector also slightly increases household incomes in Madre de Dios.

In this paper we explore the potential for a new approach to managing drought risk among rainfed rice producers in Odisha, India. Droughts have historically been a serious constraint to agricultural production in rainfed agricultural systems, with droughts resulting in significant reductions in both yields and cultivated area, in turn leading to significant impacts on rural livelihoods and food security. Scientists and policy makers have proposed various strategies for managing risks, with limited success. In this study we consider two such strategies, specifically drought-tolerant rice and weather index insurance. While neither drought-tolerant cultivars nor weather index insurance products are perfect solutions for adequately managing drought risk in and of themselves, there is scope to exploit the benefits of each and bundle them into a complementary risk management product, specifically through proper index calibration and an optimized insurance design. In this study, we explore preferences for such a complementary risk management product using discrete choice experiments in Odisha, India. We are able to estimate the added value that farmers perceive in the bundled product above and beyond the value associated with each of the independent products. We also show that valuations are sensitive to the basis risk implied by the insurance product, with farmers less enthusiastic about risk management products that leave significant risks uninsured.

Extension and advisory services (EAS) are well recognized as a key factor in contributing to agricultural productivity and growth. However, rigorous evaluation of EAS approaches and assessment of complex national or subnational pluralistic EAS systems are rare. This working paper examines the literature on experiential and empirical insights and explores methods to assess complex pluralistic EAS systems. The authors present conceptual thinking on innovation systems and EAS, and review the IFPRI “best-fit” framework. This framework remains relevant because it is based on a holistic perspective with an impact pathway orientation. The paper aims to operationalize and improve the best-fit framework to guide the evaluation of complex EAS systems. The authors draw on and summarize existing literature to illustrate methods and tools used to analyze each component of the framework. The review pays close attention to the literature and methods for assessing the diversity of service providers and their various delivery tools and learning approaches. The discussion also pays close attention to the interaction of each component and how it affects the performance and impact of EAS from a systems perspective. This paper adds key points and considerations on how to operationalize the best-fit framework to carry out evaluations of pluralistic EAS.

To feed a growing population, agricultural productivity needs to increase dramatically. Agricultural extension information, with its public, non-rival nature, is generally undersupplied, and public provision remains challenging. In this research, we explore the effectiveness of alternative modes of agricultural extension information delivery. We test whether simple agricultural extension video messages delivered through Android tablets increase knowledge of recommended practices in seed selection, storage, and handling among a sample of potato farmers in southwestern Uganda. Using a field experiment with ex ante matching in a factorial design, we find that showing agricultural extension videos significantly affects farmers’ knowledge. However, our results suggest impact pathways that go beyond simply replicating what was shown in the video. Video messages may also trigger a process of abstraction, whereby farmers apply insights gained in one context to a different context. Alternatively, video messages may activate knowledge farmers already posses but, for some reason, do not use.

The question of how to promote structural transformation is central in fostering sustainable growth and poverty reduction in low-income countries in Africa. Following China’s domestic economic transformation and its growing outward investments in the developing world, we seek to understand how Chinese investment in Africa, particularly in manufacturing, may help to foster industrialization and in turn the structural transformation of African economies. We focus on Chinese investments and partnerships in Nigeria, a salient destination for Chinese manufacturing foreign direct investment in Africa, and examine the potential mechanisms of technology transfer that might catalyze such transformation. We find some small but significant cases of potential technology transfer, particularly through technical partnerships between firms. However, the future potential of such mechanisms will depend on the initiative of Nigerian actors to leverage Chinese investment to their interest.
