A doubling in global food demand projected for the next 50 years poses huge challenges for the sustainability both of food production and of terrestrial and aquatic ecosystems and the services they provide to society. Agriculturalists are the principal managers of global useable lands and will shape, perhaps irreversibly, the surface of the Earth in the coming decades. New incentives and policies for ensuring the sustainability of agriculture and ecosystem services will be crucial if we are to meet the demands of improving yields without compromising environmental integrity or public health.

Agricultural sustainability and intensive production practices

The State of Food and Agriculture

The 2013 Human Development Report – "The Rise of the South: Human Progress in a Diverse World" – examines the profound shift in global dynamics driven by the fast-rising new powers of the developing world and its long-term implications for human developmentChina has already overtaken Japan as the world's second biggest economy while lifting hundreds of millions of its people out of poverty India is reshaping its future with new entrepreneurial creativity and social policy innovation Brazil is lifting its living standards through expanding international relationships and antipoverty programs that are emulated worldwideBut the "Rise of the South" analyzed in the Report is a much larger phenomenon: Turkey, Mexico, Thailand, South Africa, Indonesia and many other developing nations are also becoming leading actors on the world stage

Human Development Report 2013. The Rise of the South: Human Progress in a Diverse World

As efforts to mitigate climate change increase, there is a need to identify cost-effective ways to avoid emissions of greenhouse gases (GHGs). Agriculture is rightly recognized as a source of considerable emissions, with concomitant opportunities for mitigation. Although future agricultural productivity is critical, as it will shape emissions from conversion of native landscapes to food and biofuel crops, investment in agricultural research is rarely mentioned as a mitigation strategy. Here we estimate the net effect on GHG emissions of historical agricultural intensification between 1961 and 2005. We find that while emissions from factors such as fertilizer production and application have increased, the net effect of higher yields has avoided emissions of up to 161 gigatons of carbon (GtC) (590 GtCO2e) since 1961. We estimate that each dollar invested in agricultural yields has resulted in 68 fewer kgC (249 kgCO2e) emissions relative to 1961 technology ($14.74/tC, or ∼$4/tCO2e), avoiding 3.6 GtC (13.1 GtCO2e) per year. Our analysis indicates that investment in yield improvements compares favorably with other commonly proposed mitigation strategies. Further yield improvements should therefore be prominent among efforts to reduce future GHG emissions.

Greenhouse gas mitigation by agricultural intensification

This report assembles and assesses new evidence regarding investments in agricultural R&D, tracking global trends over the past several decades, and highlighting the critical importance that the accumulated stock of scientific knowledge has for today's productivity and for future innovations and economic growth.

Slow magic: agricultural R&D a century after Mendel.

"Sustained, well-targeted, and effectively used investments in R&D have reaped handsome rewards from improved agricultural productivity and cheaper, higher quality foods and fibers. As we begin a new millennium, the global patterns of investments in agricultural R&D are changing in ways that may have profound consequences for the structure of agriculture worldwide and the ability of poor people in poor counties to feed themselves. This report documents and discusses these changing investment patterns, highlighting developments in the public and private sectors. It revises and carries forward to 2000 data that were previously reported in the 2001 IFPRI Food Policy Report Slow Magic: Agricultural R&D a Century After Mendel. Some past trends are continuing or have come into sharper focus, while others are moving in new directions not apparent in the previous series. In addition, this report illustrates the use of spatial data to analyze spillover prospects among countries or agroecologies and the targeting of R&D to address specific production problems like drought-induced production risks."

Agricultural Research: A Growing Global Divide?

Investments in african agricultural research

Research has shown that women, when given the capital and opportunity, make unique, positive contributions to development outcomes ranging from agricultural productivity to poverty reduction. It comes as little surprise, then, that agricultural research, development, and extension systems are generally more successful when scientists, researchers, and extension agents pay attention to gender issues. However, women continue to be underrepresented and underserved, and their contributions remain mostly untapped in national and international agricultural research. Worldwide, gender roles are culturally defined in all aspects of farming, from control of resources to production and marketing, and these definitions constrain and marginalize women. Even within the agricultural research community, most scientists and extension agents are male.Engendering Agricultural Research, Development, and Extension argues that the paradigm for agricultural and food security development needs to move beyond a focus on production and toward a broader view of agricultural and food systems, one that recognizes women's distinct role in ensuring the food security of their households. Incorporating gender issues into agricultural research and paying attention to gender sensitivity when developing extension systems is necessary to meet the needs and preferences of men and women, satisfy the food needs of future populations, and improve the welfare of the poor.

This paper makes a case for gender equity in the agricultural RD conducting the research itself; designing, implementing, and adopting extension services; and evaluating their impacts. It concludes with recommendations regarding how to make these suggested changes.
