This valuable book summarizes recent research by experts from both the natural and social sciences on the effects of population growth on land use. It is a useful introduction to a field in which little quantitative research has been conducted and in which there is a great deal of public controversy. The book includes case studies of African, Asian, and Latin American countries that demonstrate the varied effects of population growth on land use. Several general chapters address the following timely questions: What is meant by land use change? Why are ecological research and population studies so different? What are the implications for sustainable growth in agricultural production? Although much work remains to be done in quantifying the causal connections between demographic and land use changes, this book provides important insights into those connections, and it should stimulate more work in this area.

This book provides a thorough introduction to and examination of agricultural value chains in Sub-Saharan Africa. First, the authors introduce the economic theory of agri-food value chains and value chain governance, focusing on domestic and regional trade in (and consumption of) food crops in a low-income country context. In addition to mainstream and heterodox thinking about value chain development, the book pays attention to political economy considerations. The book also reviews the empirical evidence on value chain development and performance in Africa. It adopts multiple lenses to examine agricultural value chains, zooming out from the micro level (e.g., relational contracting in a context of market imperfections) to the meso level (e.g., distributional implications of various value chain interventions, inclusion of specific social groups) and the macro level (underlying income, population and urbanization trends, volumes and prices, etc.).Furthermore, this book places value chain development in the context of a process the authors refer to as structural transformation 2.0, which refers to a process where production factors (labor, land and capital) move from low-productivity agriculture to high-productivity agriculture. Finally, throughout the book the authors interpret the evidence in light of three important debates: (i) how competitive are rural factor and product markets, and what does this imply for distribution and innovation? (ii) what role do foreign investment and factor proportions play in the development of agri-food value chains in Africa? (iii) what complementary government policies can help facilitate a process of agricultural value chain transformation, towards high-productive activities and enhancing the capacity of value chains to generate employment opportunities and food security for a growing population.

China is perhaps the most prominent example of a developing country that has transitioned from taxing to supporting agriculture. In recent years, Chinese price supports and subsidies have risen at an accelerating pace after they were linked to rising production costs. Per-acre subsidy payments to grain producers now equal 7 to 15 percent of those producers' gross income, but grain payments appear to have little influence on production decisions. Chinese authorities began raising price supports annually to bolster incentives, and Chinese prices for major farm commodities are rising above world prices, helping to attract a surge of agricultural imports. U.S. agricultural exports to China tripled in value during the period when China's agricultural support was accelerating. Overall, China's expansion of support is loosely constrained by World Trade Organization (WTO) commitments, but the country's price-support programs could exceed WTO limits in coming years. Chinese officials promise to continue increasing domestic policy support for agriculture, but the mix of policies may evolve as the Chinese agricultural sector becomes more commercialized and faces competitive pressures.
