Habitat fragmentation in Nigeria: A cryptic but devastating phenomenon that requires urgent attention

In Nigeria, habitat fragmentation, the division of natural habitat into progressively smaller and more isolated fragments separated by a matrix of human-transformed land cover, continues at an accelerating rate and accounts for most biodiversity losses. It implies a loss of habitat, reduced patch size and an increasing distance between patches. The causes of habitat fragmentation through anthropogenic activities are many and the effects of habitat fragmentation on biodiversity are huge. These effects are so diverse that different authors measure fragmentation in different ways and draw different conclusions. Some of the effects on ecosystem include; edge effect, reduction of gene pool, extinction, climate change and total collapse of an ecosystem. In Nigeria, local and international organizations and agencies have responded to this situation in so many ways, but cannot be said to have recorded any meaningful success. The failure of these measures to produce the desired results calls for concern and has been attributed to public apathy, low level of funding, inadequate game laws and weak enforcement of existing legal provision. It is expected that improvement on the aforementioned limiting factors will go a long way in reducing habitat fragmentation in Nigeria.
