Mapping Poverty and Nutrition in Nigeria Track: Sustainable Development and Humanitarian Affairs Author(s): Christopher Legg Poverty and malnutrition are persistent problems in Africa. Alleviation of these closely-related socio-economic problems must be guided by knowledge of their spatial distribution and relationships to biophysical and development factors. Two country-wide surveys, one on rural livelihoods, poverty and food demand, and the other on food consumption and child nutrition, were carried out in Nigeria by IITA, and the results mapped in order to assist interpretation. Two techniques were used to extrapolate point data from households and villages to larger areas. The first uses linear regression of poverty, development and nutrition indicators against biophysical and socio-economic variables such as vegetation cover and annual rainfall. Regression equations were developed for each sampled state and applied to surrounding states with similar agro-ecology and farming systems. The second method used models of spatial distribution and intrinsic variance of the poverty variables to estimate values between sample sites, an application of geostatistics. The two methods result in broadly similar maps.
