The adoption of machinery in agricultural production in Africa south of the Sahara has been far behind the level of mechanization found in Asia and Latin America. However, recent survey data have revealed high levels of machinery use in localized areas of cereal production in northern Ghana. A survey conducted by the International Food Policy Research Institute, in partnership with the Savannah Agriculture Research Institute, found that in some areas more than 80 percent of farmers were using machinery for at least one operation. This paper considers the theoretical drivers of agricultural intensification, as outlined by Boserup, Pingali, and Binswanger, and the extent to which they are able to explain the spatial variation in machinery use found in northern Ghana. Population pressure, market access, and agroecological conditions are considered key drivers that cause farmers to find ways to increase productivity and adopt new technologies. Combining survey data with geospatial datasets, the empirical analysis finds that population growth and travel time to the local urban center explain a significant and large proportion of the variation in machinery use by farmers.

The extent of market integration and transmission of food price shocks is a major determinant of price stability and overall food security, particularly in developing countries. Few studies have examined these issues for countries in Central Asia, however. This paper aims to fill this gap by examining wheat market integration and price transmission in Tajikistan, the most food-insecure country in Central Asia. In particular, in this study we measure how well wheat market prices in Tajikistan are integrated with international and regional markets, as well as domestically with each other. Subsequently, we assess the nature of price transmission between these markets. Using horizontal price transmission analysis and asymmetric price relationships, a.k.a. rockets and feathers, we demonstrate how prices change in peripheral food-shortage markets compared to markets located in zones with abundant local production.

The pulse sector is undergoing dynamic changes globally and in several regions and countries to meet the challenge of growing demand in the face of sluggish production growth. Realizing the importance of pulses in the human diet, 2016 has been declared the International Year of Pulses (IYP). This report captures the dynamics of the pulse sector during the last three decades. The examination of pulse supply, demand, uses, trade, prices, and outlook would help researchers and policy makers make more informed decisions related to the sector. Pulse-based food is an important source of dietary protein and essential minerals, particularly for the vegetarian population. At the global level, the average share of pulses is only 5 percent of the total protein consumption but their contribution in several developing countries range between 10 and 40 percent. To meet the growing demand and raise their per capita availability, countries made efforts to increase production and explore trade opportunities to augment domestic supply. Overall between 1980 and 2013, pulses production at the global level grew at an annual rate of 1.3 percent but there were, however, two phases of pulses production at the global level. While there was almost a period of stagnation in production of pulses during the1990s, production has sharply increased since 2005. The bulk of the increase in production came from developing countries where both area and yield growth (from a low base) contributed to the production. For developed countries—where production also grew—the center of production shifted from Europe to North America and Oceania. For developing countries, two new centers of production emerged in Eastern Africa and Southeastern Asia (Myanmar).

There has been a surge in the attention to sustainable agricultural mechanization for Africa. The need to support agricultural mechanization in the value chain in order to achieve agricultural and rural development is well recognized. Therefore, it is vital to address the major challenge of ensuring that business models for mechanization hire services driven by the private sector (including farmers, cooperatives, and small and medium enterprises) are not only profitable, sustainable and inclusive for smallholder farmers and vulnerable community members including women and youth, but also resilient to the effects of climate change. For a better understanding of how agricultural mechanization hire service provision can contribute to agricultural and rural development, this publication aims to (i) showcase a variety of business models of private-sector businesses providing agricultural mechanization hire services in Africa, (ii) identify success factors, and (iii) provide entry points for investment.

To understand whether and how inverse relationship between farm size and productivity changes when labor market performance improves, we use large national farm panel from India covering a quarter-century (1982, 1999, 2008) to show that the inverserelationship weakened significantly over time, despite an increase in the dispersion of farm sizes. A key reason was the substitution of capital for labor in response to nonagricultural labor demand. In addition, family labor wasmore efficient than hired labor in the 1982–1999 period, but not during the 1999–2008period.In line with labor market imperfections as a key factor, separability of labor supply and demand decisions cannot be rejected in the second period,except in villages with very low nonagricultural labor demand.

This paper examines the development of US agricultural policy and considers how it has affected US consumers and producers, as well as how US programs affect foreign producers and consumers within the context of the United States’ obligations under the World Trade Organization. Throughout its history, the United States has supported the farm sector through a myriad of policies affecting prices, production, and farm incomes. Although many of the policies put in place during the New Deal legislation in the 1930s were seen as temporary at the time, most have persisted in one form or another to the present day. And while many would argue that the form and function of today’s agricultural programs are less distortionary than before, the level of support provided to the sector is several billion dollars annually.

The primary goal of the study is to investigate the potential to expand oilseeds, specifically soybeans,as an alternative commercialcrop to tobacco among Malawian farmers. A principal motivation for undertaking the study at the microeconomic level is to determine, in a theoretically consistent fashion, the type of policy and economic environment under which farmers begin to shift more of their scarce resources to oilseed production.The study aims to provide recommendations to a growing demand among policy makers and development partners for a greater diversification of exports and crop production systems of the majority smallholder farmers in Malawi. Using representative farm models, the study examinesthe potential for expanding production of soybeans among typical smallholder farming systems in Malawi. The results will help guide future policies and investments targeted at promoting greater crop diversification and incomes, in order to reduce poverty and malnutrition in Malawi. Given the amount of labor and land resources allocated to maize production for food security purposes, we also consider the policy challenges that emerge for crop diversification as a result
