Book Description
A total of 289 studies of returns to agricultural R&D were compiled and these provide 1821 estimates of rates of return. After removing statistical outliers and incomplete observations, across the remaining 1128 observations the estimated annual rates of return averaged 65 per cent overall; 80 per cent for research only, 80 per cent for extension only, and 47 per cent for research and extension combined. These averages reveal little meaningful information from a large body of literature, which provides rate-of-return estimates that are often not directly comparable. This study was aimed at trying to account for the differences. Several features of the methods used by research evaluators matter, in particular assumptions about lag lengths and the nature of the research-induced supply shift.

Book Description
Enhancing the productivity of agriculture is vital for Sub-Saharan Africa's economic future and is one of the most important tools to end extreme poverty and boost shared prosperity in the region. How governments elect to spend public resources has significant development impact in this regard. Choosing to catalyze a shift toward more effective, efficient, and climate-resilient public spending in agriculture can accelerate change and unleash growth. Not only does agricultural public spending in Sub-Saharan Africa lag behind other developing regions but its impact is vitiated by subsidy programs and transfers that tend to benefit elites to the detriment of poor people and the agricultural sector itself. Shortcomings in the budgeting processes also reduce spending effectiveness. In light of this scenario, addressing the quality of public spending and the efficiency of resource use becomes even more important than addressing only the level of spending. Improvements in the policy environment, better institutions, and investments in rural public goods positively affect agricultural productivity. These, combined with smarter use of public funds, have helped lay the foundations for agricultural productivity growth around the world, resulting in a wealth of important lessons from which African policy makers and development practitioners can draw. 'Reaping Richer Returns: Public Spending Priorities for African Agriculture Productivity Growth' will be of particular interest to policy makers, development practitioners, and academics. The rigorous analysis presented in this book provides options for reform with a view to boosting the productivity of African agriculture and eventually increasing development impact.

Book Description
Science for Agriculture was the first thorough quantitative and analytical treatment of the history of the U.S. agricultural research system and as such has served as the foundation for research over the 10 years since its publication. The benefits from public and private investment in agricultural research are immense and should be understood by every student of the agricultural science system in the United States. The second edition updates important landmarks, components, characteristics, and trends of the U.S. system for developing and applying science to increase the productivity and advancements of agriculture. Science for Agriculture, 2e, is essential reading for agriculture educators and researchers, Land Grant administrators, food and agri-industry R&D and all others who need to understand the factors that will influence future public agricultural research policy.

Book Description
An examination of technology transfer in agricultural research collaborations Public-Private Collaboration in Agricultural Research: New Institutional Arrangements and Economic Implications examines the impact of the private-sector takeover of the field, and what it means for funding, research, technology, and more. Beginning with U.S. agricultural research financing, the discussion moves on to cover plant and animal research investments, collaborating institutions, and the international significance of technology spillover and transfer. From intellectual property rights and the CRADA Model to seed generation and other agricultural technology, this book offers a thought-provoking overview of global collaboration at this critical intersection of science and human welfare.

Book Description
This title was first published in 2002: This volume represents some of the proceedings of the 24th conference of the International Association of Agricultural Economists (IAAE) held in Berlin, Germany, in August 2000. The papers in this volume include the president's address, the Elmhirst Lecture and a selection of 20 contributed papers. It also includes panel discussion reports, reports on the discussion groups and mini-symposia, poster paper abstracts, and the synoptic view presented at the close of the conference by the new president of the IAAE, Joachin von Braun. The theme of the 24th conference was "Tomorrow's Agriculture: Incentives, Institutions, Infrastructure and Innovations", reflecting the rapid advances being made in the application of biotechnology in both the developed and developing worlds.

Book Description
This analysis explores the relationship between agricultural R&D investments and rural poverty reduction, and the prevalence of undernourishment in sub-Saharan Africa (SSA). It uses a panel data set of internationally comparable poverty dis-aggregated by urban and rural areas, country level undernourishment, and ASTI data on R&D investments and derived indicators. The study uses agricultural R&D knowledge stocks (KS) to account for the lagged effects of research through depreciation and gestation period of investments, and applies causal mediation analysis to assess the impact of KS on poverty and hunger and measure the relative contribution of KS-induced agricultural productivity growth on those outcomes. Evidence suggests that, while SSA growth in KS has been relatively slow, it helped reduce rural poverty and undernourishment – the percentage point reduction in rural extreme and moderate poverty of a 1% annual increase in KS is 0.218 and 0.146 percentage points per year, respectively. Mediation analysis indicates that a fifth of the KS effect on extreme rural poverty, and a quarter of the KS effect on moderate rural poverty, can be attributed to KS driven gains in agricultural labor productivity. Likewise, KS growth reduces undernourishment – a 1% annual increase in KS leads to a drop of 0.132 percentage points per year in the prevalence of undernourishment, with about 40% of that effect mediated through gains in agricultural land productivity. These results indicate that KS supports poverty and hunger reduction through benefits on-farm and beyond it. They also suggest that there is room for strengthening the role of R&D KS productivity enhancing innovations. Given the current low levels of investments in R&D and resulting KS, increasing its levels will be critical, but that alone is not sufficient. Policy makers will have to rethink the way the innovations from R&D get scaled up and pay attention to the necessary complementary policies and investments that enable a sustainable pathway leading to greater productivity growth and development impacts.
