Land Policy and Food Prices: Evidence from a Land Consolidation Program in Rwanda
Abstract Rwanda’s “Crop Intensification Program (CIP)” is primarily a land consolidation program aimed at improving agricultural productivity and food security. The program, which began in 2007, focuses on monocropping and commercialization of six priority crops: maize, wheat, rice, white potato, beans, and cassava. CIP has facilitated easy access to improved seed stocks, fertilizer, extension services, and postharvest handling and storage services. Although studies have documented the impact of CIP on changes in farm yield, incomes, and productivity, less is known about its impact on food prices. In this study, we examine the crop-food price differences in intensive monocropped CIP and non-intensive monocropped CIP zones in Rwanda. Specifically, the study evaluates price variations of beans and maize along with complementary food crops in intensive and non-intensive monocropped zones before and after the introduction of the CIP policy. We find that the CIP policy is not associated with differences in CIP crop prices between the intensive and non-intensive monocropped zones. Over time, prices increased for CIP crops but generally, the crop prices in the two zones were cointegrated. Prices for non-CIP crops in the two different zones did show price differentials prior to the implementation of CIP, with the prices in intensive monocropped zones being greater than in the non-intensive monocropped zones. Moreover, the prices in intensive areas are cointegrated with prices in non-intensive areas for maize and beans and these prices are converging. This indicates that farmers who intensively produced one CIP crop were able to go to the market and purchase other food crops and that price differences between zones have decreased over time, potentially making the CIP intensive farmers better off.
期刊介绍:
The Journal of Agricultural & Food Industrial Organization (JAFIO) is a unique forum for empirical and theoretical research in industrial organization with a special focus on agricultural and food industries worldwide. As concentration, industrialization, and globalization continue to reshape horizontal and vertical relationships within the food supply chain, agricultural economists are revising both their views of traditional markets as well as their tools of analysis. At the core of this revision are strategic interactions between principals and agents, strategic interdependence between rival firms, and strategic trade policy between competing nations, all in a setting plagued by incomplete and/or imperfect information structures. Add to that biotechnology, electronic commerce, as well as the shift in focus from raw agricultural commodities to branded products, and the conclusion is that a "new" agricultural economics is needed for an increasingly complex "new" agriculture.
