<P> Nigeria's Delta region, home of the large oil industry, experiences serious oil spills and other environmental problems, which has caused conflict . </P> <P> Waste management including sewage treatment, the linked processes of deforestation and soil degradation, and climate change or global warming are the major environmental problems in Nigeria . Waste management presents problems in a mega city like Lagos and other major Nigerian cities which are linked with economic development, population growth and the inability of municipal councils to manage the resulting rise in industrial and domestic waste . This huge waste management problem is also attributable to unsustainable environmental management lifestyles of Kubwa Community in the Federal Capital Territory, where there are habits of indiscriminate disposal of waste, dumping of waste along or into the canals, sewerage systems that are channels for water flows, and the like . </P> <P> Haphazard industrial planning, increased urbanisation, poverty and lack of competence of the municipal government are seen as the major reasons for high levels of waste pollution in major cities of the country . Some of the' solutions' have been disastrous to the environment, resulting in untreated waste being dumped in places where it can pollute waterways and groundwater . </P> <P> In 2005 Nigeria had the highest rate of deforestation in the world, according to the Food and Agriculture Organization of the United Nations (FAO).

Between 1990 and 2000, Nigeria lost an average of 409,700 hectares of forest every year equal to an average annual deforestation rate of 2.38% . Between 1990 and 2005, in total Nigeria lost 35.7% of its forest cover, or around 6,145,000 hectares . </P>
