Research Highlights

Cover Atlas of African Ag

Years of weathering have leached nutrients away from many soils in the cropped areas of Africa south of the Sahara (SSA).

Our new spatial output indexes show that 16 to 21 percent of the increase in U.S. corn output over the 128 years beginning in 1879 was attributable to spatial movement in production.

This technical note describes the methods and data sources used to generate the results reported in: Pardey et al. (2013).

We estimate global wheat losses over the past 50 years absent investments in research to limit impacts of stem rust and discuss how this can inform decisions about “right-sizing” research investments.

Median travel time to human settlement of 50,000 or greater population.

We clarify the terminology surrounding yield gaps, show that closing yield gaps is not necessarily economic, and conclude that food security will be better served by policies that directly enhance the productive capacity of agriculture to supply affordable food efficiently and sustainably.

Study evaluates the potential impacts of 'Drought Tolerant Maize for Africa' project run by CIMMYT and IITA in 13 sub-Saharan African countries.

Model-estimated yield variability of rainfed maize with high input for 1981-2010 (30-year period). Values are for 5 arc-minute grid cells.
