Agriculture is one of the main economic activities in the world, with its significance magnified especially
among the world’s poor. This paper seeks to explore how climate change would impact on
the agricultural sector and consequently food security. Agricultural activities in most developing
countries entirely depend on rainfall patterns, on the contrary, climate change has emerging as an
environmental challenge with adverse impacts expected on food security. This is mainly through
incidences of changes in water availability, floods and drought. For example, changes in temperature
and precipitation including drought affects crop and livestock yield, hydrologic balances, input
supplies and other components of agricultural systems. Equally important, environmental degradation
is one of the drivers of climate change that further undermines sustainability of agriculture.
Climate change is real and already taking place. According to the inter-governmental panel
on climate change (IPCC), warming temperatures are projected to cause more frequent and
more intense extreme weather events such as heavy rain storms, flooding and tropical storms and
in some cases drought in many parts of the country. Agriculture is one of the most climate sensitive
sectors, with projections that 800 million people are currently food insecure. Additionally, it
has the potential to undermine advances in poverty reduction and sustainable development. Thus,
fundamental changes in agricultural systems are needed because climate change poses new and
serious challenges for farmers hence food insecurity. Most important, agricultural adaptation and
mitigation pathways need to be developed so as to avoid further threat on food security.
