To understand the impacts of support programs on global emissions, this paper considers the impacts of domestic subsidies, price distortions at the border, and investments in emission-reducing technologies on global greenhouse gas (GHG) emissions from agriculture. In a step towards a full evaluation of the impacts, it uses a counterfactual global model scenario showing how much emissions from agricultural production would change if agricultural support were abolished worldwide. The analysis indicates that, without subsidies paid directly to farmers, output of some emission-intensive activities and agricultural emissions would be smaller. Without agricultural trade protection, however, emissions would be higher. This is partly because protection reduces global demand more than it increases global agricultural supply, and partly because some countries that currently tax agriculture have high emission intensities. Policies that directly reduce emission intensities yield much larger reductions in emissions than those that reduce emission intensities by increasing overall productivity because overall productivity growth creates a rebound effect by reducing product prices and expanding output. A key challenge is designing policy reforms that effectively reduce emissions without jeopardizing other key goals such as improving nutrition and reducing poverty. While the scenario analysis in this paper does not propose any particular policy reform, it does provide an important building block towards a full understanding the impacts of repurposed agricultural support measures on mitigation of greenhouse gas emissions and adaptation to climate change. That full analysis is being undertaken in subsequent work, which will also take account of land-use change and alternative forms of agricultural policy support to align objectives of food security, farmers’ income security, production efficiency and resilience, and environmental protection.

"The challenges facing agriculture are plenty. Along with the world's growing population and diminishing amounts of water and arable land, the gradual increase in severe weather presents new challenges and imperatives for producing new, more resilient crops to feed a more crowded planet in the twenty-first century. Innovation has historically helped agriculture keep pace with earth's social, population, and ecological changes. In the last 50 years, mechanical, biological, and chemical innovations have more than doubled agricultural output while barely changing input quantities. The ample investment behind these innovations was available because of a high rate of return: a 2007 paper found that the median ROI in agriculture was 45 percent between 1965 and 2005. This landscape has changed. Today many of the world's wealthier countries have scaled back their share of GDP devoted to agricultural R&D amid evidence of diminishing returns. Universities, which have historically been a major source of agricultural innovation, increasingly depend on funding from industry rather than government to fund their research. As Upton Sinclair wrote of the effects industry influences, "It is difficult to get a man to understand something when his salary depends upon his not understanding it." In this volume of the NBER Conference Report series, editor Petra Moser offers an empirical, applied-economic framework to the different elements of agricultural R&D, particularly as they relate to the shift from public to private funding. Individual chapters examine the sources of agricultural knowledge and investigate challenges for measuring the returns to the adoption of new agricultural technologies, examine knowledge spillovers from universities to agricultural innovation, and explore interactions between university engagement and scientific productivity. Additional analysis of agricultural venture capital point to it as an emerging and future source of resource in this essential domain"--

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.

This book takes forward our understanding of agricultural input subsidies in low income countries.

China and India are the most extraordinary economic success stories of the developing world. Both nations’ economies have grown dramatically over the past few decades, elevating them from two of the world’s poorest countries into projected economic superpowers. As a result, the numbers of Chinese and Indians living in poverty have rapidly fallen and per capita incomes in China and India have quadrupled and doubled, respectively. This book investigates the reasons for these staggering accomplishments and the lessons that can be applied both to other developing nations and to the problem of poverty that remains in these two countries. The contributors pay particular attention to agriculture and the rural economy, examining how initial conditions and investments and the prioritization and sequencing of different policies and strategies have led to successes, and how the agricultural and rural sectors connect to overall economic expansion. They also emphasize the importance of anti-poverty programs and safety nets in helping poor people escape poverty. The book offers a set of policy and strategic options for future growth and poverty reduction. These include setting the right priorities for public spending, identifying trade and market reforms, building social safety nets for the poorest of the poor, and building accountable institutions that can provide public goods and services effectively. The book concludes by examining future challenges to China and India’s economic development, such as the need to ensure growth that is sustainable, equitable, and environmentally friendly. The Dragon and the Elephant offers valuable insights to development specialists anxious to multiply the benefits experienced by two of the greatest economic successes in recent times.

The book highlights proceedings from the Berlin 2008: Agriculture and Development conference held in preparation for the World Development Report 2008.
