Urban Health and Welfare in Sub-Saharan Africa: Population Growth, Urbanisation, Water/Sanitation Services, Slumisation and Poverty

Abstract

Spatio-temporal analysis was applied on data representing urbanisation, slumisation, poverty, safe water/ sanitation in urban sub-Saharan Africa (SSA). The findings include: rapid rates of national population growth and urbanisation throughout SSA from 1980 to 2005, averaging 93.8% (range: 90.5% points), lowest and highest rates being 40% (Lesotho) and 130.5% (Niger), respectively; high national poverty rates, widespread in SSA: (>50% in about seven countries; it might have been similar in more countries if a large number of SSA countries had reported their 1993 poverty rates; high urban/rural poverty ratios (1.05-1.79 points range) between Nigeria and Benin Republics. High average rate (73%) of slumisation in SSA in 2001 (range: 96%), lowest and highest rates being in Zimbabwe (3%) and Chad/Ethiopia (99%), respectively. SSA’s 2000 health adjusted life expectancy was generally low: 38.8 years (<40 years in 24 countries). Use of safe/improved water/sanitation services were poor almost throughout SSA: declined rapidly and ubiquitously from 72% (2000) to 55% (2002), minus 17% points decrease in three years within individual countries with alarming declines up to minus 69% points in Guinea. The policy implications of the findings include the urgent and imperative need to massively implement urban improvement programmes designed to provide health-inducing services/facilities across SSA.
