CHAPTER ONE
INTRODUCTION
Background of the Study
Climatic change is one of the greatest environmental issues of our time. There is a general consensus among scientists, economists and policy makers that the entire globe is facing a real and serious long term threat from climatic change (Obioha, 2009; Hanseur, Baethgeri, Osgood, Ceceato, et al, 2007).
According to Goni et al, (2011), projections by experts suggests that by the end of the 21st century climatic change would have had substantial impact on agricultural production and hence, on the scope for reducing poverty.
The inter-governmental panel on climatic change (IGPC, 2007) defined climatic change as statistically significant variations in climate that persist for an extended period, typically decades or longer. It includes shift in the frequency and magnitude of sporadic weather even as well as the slow continuous rise in global mean surface temperature. The main causes are the increase in greenhouse gas (GHG) emissions, particularly carbon dioxide (FAO, 2008).
Climatic change is a change in climate that is attributable directly and indirectly to human conditions. It affects atmospheric condition of the earth thereby leading to global warming. According to Raymond and Victoria (2008), climatic change has the potential to affect all natural systems thereby becoming a threat to human development and survival socially, politically and economically. A comprehensive summary by the inter-governmental panel on climatic change in 2007 stated that human actions are very likely the cause of global warming; meaning a 90% or greater probability is attributable to man. Various activities carried out by man have varying contribution to change in climate system. The burning of coal, oil and various agricultural and industrial practices, are altering the composition of the atmosphere and are contributing to climatic change. This human activity leads to increased atmospheric concentration of the number of greenhouse gases which in turn produce greenhouse effect.
