vegetation, forest, agricultural land, wetlands and natural drainages to built-up environments and
construction impacts on climate. Changes in climate patterns alter the spatial and temporal
distribution of hydrological characteristics with inevitable consequences that are very significant.
The impact of climate change which includes, erosion, drought, landslides and floods have very
serious consequences on the environment, human beings and their socio-economic activities.
Climate change may also increase the frequency, magnitude and the seasonality of extreme events,
especially floods.
