Social Impact of global Environmental Change on Farming Communities on the Ogoli River Bank in Otukpo Area of Benue State, Nigeria

One of the manifestations of the global change in this study area is a marked reduction in the duration and amount of rainfall. This adversely affects the volume of the head waters that ultimately determine the volume of the Ogoli River which is used for irrigation. Consequently, food security and livelihood of the farming communities whose mode of agricultural production is rain-fed is adversely affected.

Global Climate Change: Past and Future

My presentation will begin with a review of the now-solid evidence for a human influence on the climate of recent decades.

I will then address how the study of paleoclimate can inform our assessments of the potential future impacts of human-induced climate change.
