Climate change will impact agriculture and food production around the world due to; the effects of elevated Carbondioxide (CO2) in the atmosphere, higher temperature, altered precipitation and transpiration regimes, increased frequency of extreme events, and modified weed, pest and pathogen pressure. Data for this study were collected from primary and secondary sources. Primary source of data were collected using two sets of structured questionnaires. A total number of three hundred (300) questionnaires were administered on two categories of respondents in this study. Results from this study revealed that Food Crops are the major crops cultivated in the study area, and the effects of climate change on agricultural production results to soil loss, plant nutrient loss, textural change, increase in pests and diseases and poor yield germination etc. This study therefore recommended that cover trees should be planted, which will provide shade and reduce heat, due to climate change and the preservation of underground water. Keywords: Agricultural Production, Climate-Change, Environmental Impact.

Climate change and agriculture are interrelated processes, both of which take place on a global scale (Jeremy, 2008). Environmental impact of agriculture varies based on the wide variety of agricultural practices employed around the world. Global warming is projected to have significant impacts on conditions affecting agriculture including temperature, precipitation and glacial run-off. These conditions determine the carrying capacity of the biosphere to produce enough food for the human population and domesticated animals (Marcoux, 2000). Rising levels of carbondioxide would also have effects, both detrimental and beneficial on crop yield. The overall effect of climate change on agriculture will depend on the balance of these effects. Assessment of the effects of global changes on agriculture might help to properly anticipate and adapt farming to maximize agricultural production. United Nations Report (2010) states that agriculture has shown to produce significant effects on climate change, primarily through the production and release of greenhouse gases such as carbon dioxide, methane and nitrous oxide, but also by altering the earth's land cover, which can change its ability to absorb or reflect heat and light, thus contributing to radioactive forces. Land use change, such as deforestation and desertification, together with the use of fossil fuels are the major Journal of Environmental Issues and Agriculture in Developing Countries, Vol. 3, No. 2 August 2011


anthropogenic sources of carbon dioxide, agriculture itself is the major contributor to increasing methane and nitrous oxide concentrations in earth's atmosphere (United Nations, 2010). The exponential population increase in recent decades has increased the practice of agricultural land conversion to meet demand for food, which in turn has increased the effects on the environment. The global population is still increasing and will eventually stabilize, as some critics doubt that food production, due to lower yields from global warming, can support the global population (United Nations, 2008). Environment as defined by Afolabi (2005) is itself, the point in which one is found at a time, the surroundings, the more distant places, other earth components, conditions, prospects and problems, which account for its flourishing or otherwise. In general, the environment provides all life support system in the air, water, on land and in the forests (Glasson et al., 1999). Environmental problems therefore manifest as a result of different activities...
