CLIMATE CHANGE AND AGRICULTURAL PRODUCTIVITY IN SUB-SAHARAN AFRICA: A SPATIAL SAMPLE SELECTION MODEL AgEcon
Ward, Patrick S.; Florax, Raymond J.G.M.; Flores-Lagunes, Alfonso.
Using data at a high spatial resolution, we estimate a cereal yield response function conditional upon climatological and topographical features using a recently developed estimator for spatial process models when sample selection is of concern. We control for localized spatial correlation in unobserved disturbances affecting both the selection to plant cereals as well as in the resulting conditional yield response. We find that cereal yields across Sub-Saharan Africa will decline with increasing temperatures resulting from global climate change, and that failing to control for sample selection leads to underestimation of these adverse effects.

Disaster Risk, Social Vulnerability and Economic Development AgEcon
Ward, Patrick S.; Shively, Gerald E..
We examine the extent to which economic development reduces both a country's disaster risk and its social vulnerability to climate-related disasters. Global climate change is expected to increase the frequency and intensity of extreme weather events, such as droughts, floods, and various types of storms. Moreover, the effects of these extreme weather events are expected to be borne disproportionately in areas of the world already challenged by underdevelopment. We find that the ability of economic development to reduce disaster risk depends on a country's income level; additional income becomes less effective in reducing disaster risk as countries become wealthier. We find that, conditional on a disaster occurring, higher incomes generally reduce a...

Agricultural Productivity and Anticipated Climate Change in Sub-Saharan Africa: A Spatial Sample Selection Model AgEcon
Ward, Patrick S.; Florax, Raymond J.G.M.; Flores-Lagunes, Alfonso.
A cereal yield response function is estimated conditional upon environmental and topographical features to detect the effects of spatial heterogeneity and spatial dependence in explaining agricultural productivity across Sub-Saharan Africa. Controlling for direct and localized spillover effects, we then estimate the effect that projected changes in temperature and precipitation as a result of global climate change will have on agricultural production. We find that the estimated declines found in the climatological literature may overestimate actual declines, and factors such as spatial heterogeneity (i.e., country fixed effects) are profoundly more important to agricultural production.

Migration and Land Rental as Risk Response in Rural China AgEcon
Ward, Patrick S.; Shively, Gerald E..
Households in developing countries take various actions to smooth income or consumption as a means of managing or responding to risk. One of the principal means of smoothing income is through the diversification of income sources, including non-farm employment and rural-urban migration. An important consumption smoothing strategy involves the accumulation and depletion of assets. We examine migration and land rental market participation as responses to risk in rural China. Using a longitudinal data set comprised of households in nine provinces in China from 1991 through 2006, we are able to test for the effect of various manifestations of underlying idiosyncratic and covariate income risk on household responses. We find that covariate risks increase...
