Ecological cost of city growth in Africa: The experience of Kano in Nigeria

Aliyu Barau, Federal College of Education, Kano

From 30,000 inhabitants in the 19th century to over 3,000,000 now, the rapid population growth in Kano is fuelled by in-migration induced by urban development bias, land ownership issues and decline of agricultural sector in the Nigerian economy. Urbanisation has its cost and implications on the environment and inhabitants. within the last three decades, open spaces and city ponds have sharply reduced in quantity and quality; vegetation density has declined; city wildlife is now too rare; flooding and outbreak of epidemics are recurrent; squalors continue to emerge as microclimate is undesirable. Urban agriculture has faded, children/youths playgrounds are missing; the city is hot, dusty and smoky. To examine the situation, an Air-photo mosaic of 1960s and Quick-bird satellite imagery (2003) of the city are used in investigating the situation. Interviews, field, meteorological and literature studies form other research aspects. Recommendations for public/private/civil society participatory reversal actions for sustainability are made.
