Satellite Evidence for Yield Growth Opportunities in Northwest India

David Lobell, J. Ivan Ortiz-Monasterio, Anna S. Lee
Field Crops Research , 2010

Improving crop yields in major agricultural regions is one of the foremost scientific challenges for the next few decades. In Northwest India, the stagnation of wheat yields over the past decade presents a distressing contrast to the tremendous yield gains achieved during the Green Revolution. One commonly proposed way to raise yields is to reduce the often considerable gap between yield potential and average yields realized in farmers' fields, yet the likely effectiveness of different strategies to close this gap has been poorly known.

The Source of the Midwinter Suppression in Storminess over the North Pacific

Sandra Penny, Gerard Roe, David S. Battisti
Journal of Climate , 2010

Feature-tracking techniques are employed to investigate why there is a relative minimum in storminess during winter within the Pacific storm track (the midwinter suppression). It is found that the frequency and amplitude of disturbances entering the Pacific storm track from midlatitude Asia are substantially reduced during winter relative to fall and spring and that the magnitude of this reduction is more than sufficient to account for the midwinter supression.

The Poverty Implications of Climate-Induced Crop Yield Changes by 2030

Thomas Hertel, Marshall Burke, David Lobell
GTAP , 2010

Accumulating evidence suggests that agricultural production could be greatly affected by climate change, but there remains little quantitative understanding of how these agricultural impacts would affect economic livelihoods in poor countries. Here we consider three scenarios of agricultural impacts of climate change by 2030 (impacts resulting in low, medium, or high productivity) and evaluate the resulting changes in global commodity prices, national economic welfare, and the incidence of poverty in a set of 15 developing countries.

Robust Negative Impacts of Climate Change on African Agriculture

Wolfram Schlenker, David Lobell
Environmental Research Letters , 2010

There is widespread interest in the impacts of climate change on agriculture in Sub-Saharan Africa (SSA), and on the most effective investments to assist adaptation to these changes, yet the scientific basis for estimating production risks and prioritizing investments has been quite limited. Here we show that by combining historical crop production and weather data into a panel analysis, a robust model of yield response to climate change emerges for several key African crops.

Solar-powered Drip Irrigation Enhances Food Security in the Sudano-Sahel

Jennifer Burney, Lennart Woltering, Marshall Burke, Rosamond L. Naylor, Dov Pasternak
Proceedings of the National Academy of Sciences , 2010

Meeting the food needs of Africa's growing population over the next half-century will require technologies that significantly improve rural livelihoods at minimal environmental cost. These technologies will likely be distinct from those of the Green Revolution, which had relatively little impact in sub-Saharan Africa; consequently, few such interventions have been rigorously evaluated. This paper analyzes solar-powered drip irrigation as a strategy for enhancing food security in the rural Sudano-Sahel region of West Africa.
