| This report has four parts. The first part focuses on the changing environment in which the international wheat research system functions in developing countries. The authors describe recent trends in developing country wheat production against projected demand for wheat. Next, they present strategies for increasing productivity in favored and less favored wheat production environments. Part 1 concludes with a discussion of how emerging trends and policies, such as intellectual property protection and market liberalization, are likely to affect the global wheat research system and exchange of germplasm. Part 2 of the report presents new information on the historical impact of the international wheat improvement system, including information on the role of... |

| This book examines future technological and policy prospects for the sustainable intensification of rainfed upland maize production in Asia, and derives R&D priorities for specific maize production environments and markets. Village-level and farmer-group surveys were conducted to characterize upland maize production environments and systems in China, India, Indonesia, Nepal, the Philippines, Thailand, and Vietnam. Survey findings, particularly farmer-identified constraints to maize production, complemented with other relevant data, were used in country-level, R&D priority-setting workshops. High on the list of farmer constraints was drought, estimated to affect three production environments that are home to about 48 million rural poor and produce... |

| Rapid economic and income growth, urbanization, and globalization are leading to a dramatic shift of Asian diets away from staples and increasingly towards livestock and dairy products, vegetables and fruit, and fats and oils. While the diversification of diets away from the traditional dominance of rice with rising incomes is expected and observed, current food consumption patterns are showing signs of convergence towards a Western diet. Globalization and the consequent global interconnectedness of the urban middle class, is the driving force behind the convergence of diets. The rapid spread of global supermarket chains and fast food restaurants are reinforcing the above trends. The following six key stylised facts characterize the changes in food... |

| This paper draws upon development economics theory, demographic projections, and empirical evidence to consider the likely consequences of the HIV/AIDS pandemic for the agricultural sector of the hardest-hit countries of Eastern and Southern Africa. We identify four processes that have been underemphasized in previous analysis: 1) the momentum of long-term population growth rates; 2) substantial underemployment in these countries’ informal sectors; 3) steady declines in land-to-person ratios in the smallholder farming sectors; and 4) effects of food and input marketing reforms on shifts in cropping patterns. The paper concludes that the conventional wisdom encouraging prioritisation of labour-saving technology or crops has been over-generalised, although... |

| Intensive double or triple monocropping of rice has caused degradation of the paddy micro environment and reductions in rice yield growth in many irrigated areas in Asia. Problems include increased pest infestation, mining of soil micronutrients, reductions in nutrient-carrying capacity of the soil, build-up of soil toxicity, and salinity and waterlogging. Emerging sustainability problems in intensive rice agriculture show the need for a greater understanding of the physical, biological and ecological consequences of agricultural intensification and greater research attention to long term management of the agricultural resource base. |

| This paper re-visits the age old proposition that agriculture growth contributes to overall economic development, and asks whether the relationship still holds in an increasingly globalized world. There is overwhelming empirical support for the above proposition, indeed, it is hard to find exceptions, barring a few city states, where sustained economic development has not been preceded by robust agricultural growth. However, there are a large number of countries that have witnessed neither agricultural growth nor economic development. Even in countries where agricultural growth has been significant, dramatic inter-regional differences persist. This paper examines the factors that contribute to or constrain the process of agricultural transformation. Does... |

| This paper presents emerging evidence pointing to the transmission to developing countries' rural spaces of the impacts of agrifood market transformation occurring at national and global levels. That transmission takes place via retail chains penetrating intermediate cities and rural towns, and urban-based food manufacturers selling products to those chains as well as to traditional shops. The paper presents and justifies three main hypotheses concerning the impacts of that penetration. (1) The direct effect is that the modern retailers and modern-sector processed products directly compete with, and present potentially major challenges to, the processed foods, farm inputs, and commercial services already being undertaken in the RNFE sector by the rural... |

| Investments over the past 35 years have created a system of national and international research centers that has revolutionized the supply of improved cereal varieties to developing country farmers. The newly created scientific ability to exploit genetic resources has been the engine of productivity growth in much of world agriculture. But the success that has been attained in building research institutions has not touched all countries or farmers, nor can it be considered permanent. The financial and political environment of the past decade has halted the expansion of agricultural research capacity and the scarcity of research resources and evolving world intellectual property rights (IPR) regimes complicates the search for stable arrangements for... |

| This paper synthesizes the evidence on cereal crop productivity in developing countries over the past 30 years and looks at future prospects for productivity growth. For more than three decades we have witnessed the phenomenal growth of cereal crop productivity in the developing world. Termed the Green Revolution, the initial phase of this growth resulted from an increase in land productivity and occurred in areas of growing land scarcity and/or areas with high land values. Significant investments in research and infrastructure development, especially irrigation, were the strategic components of this increased productivity. In the post-Green Revolution period, particularly in Asia, productivity growth has been sustained through increased input use and,... |
