Criteria for citing poverty alleviating facilities in target communities in Nigeria: A case study of Yobe State
Madaki Musa Janga

The Federal Government of Nigeria have created programmes to alleviate poverty, but indices on electricity, water, education, housing and health have shown that little have been done in the country’s effort to develop rural areas. Most of the development projects were not evenly distributed and as such very few groups of people benefited from such projects. One of the most critical decisions of poverty alleviation programme is the identification of the intended beneficiaries of the...
