No doubt all of us are facing the consequences of climate change but poor people being the most vulnerable sector of the society may find them selves in great trouble. Climate change is one of the most important global environmental challenges, with implications for food production, water supply, health, energy, etc. Food security directly or indirectly related to climate changes. Any alteration in climatic parameters such as temperature and humidity which govern crops grows will have a direct impact on the quality of food produced. This book addresses these challenges. The responsibility for greenhouse gas emissions' increase lies largely with the industrialized world, though the developing countries are likely to be the source of an increasing proportion of future emissions. The projected climate change under various scenarios is likely to have implications on food production, water supply, coastal settlements, forest ecosystems, health, energy security, etc. The adaptive capacity of communities likely to be impacted by climate change is low in developing countries. The efforts made by the Kyoto Protocol provisions are clearly inadequate to address the climate change challenge. T
