Sustainability was the idea, which wanted to enhance the economic development of the world, in lure of the future generations. The ecologists were concerned with the increasing soil erosion, water depravity and its contamination, pest attacks and their immunity to chemicals, and foremost the social and economic equity all arising t and from the lack of production and its increasing variability.Ecologists worldwide through the analysis of historical data of crop yield suggest that mankind had through decades underrated the effects that climate change has had upon agriculture, and had mistakenly related it to mismanagement of agricultural practices; however even a slight change in normal climate conditions can have a drastic effect upon the yield. Rosenzweig and some other environmentalists in their paper, “Climate Change and US Agriculture” suggest that, “Variations in conditions such as length of growing season, timing of frosts, heat accumulation, precipitation, evaporation, and moisture availability all influence production and therefore economic returns to producers and farming businesses. With the onset of greenhouse-gas-induced climate change, growing conditions and climate-related risks and opportunities are expected to change, and may already be changing” (Rosensweig et al.However, a trend that cannot be denied and has sustained through the last few decades is the general increase in temperature, reduced frequency and amount of precipitation and increase in the concentration of carbon dioxide levels, and which keep on becoming more significant with the passage of time. These changes tend to destroy the concept of sustainability in agriculture, as the natural cycle has been destroyed leaving it less dependable and efficient for the needs of the worldwide population.According to the 2003 report of UNEP (United Nations, 2003), the effects of climate change upon agriculture will vary from region to region, which would not only alter the crop yield but would also effect the biodiversity of the land, the variety of pests and insects, soil properties as well as the air conditions in the particular area. With the worsening of the global changes, it is expected that the lands, which lie in the mid latitudes, would sustain more rain, while that in the interior of continents such as Asia and Australia, will suffer from large dry spells. Less rain, greater evapotranspiration and higher temperatures
