Abstract: Assessing the impacts of climate change will be a vital task in developed as well as in developing countries because of many interdependent physical, biological and chemical processes are ongoing in earth and agricultural systems. These processes can be affected by change in climate, causing an effect on natural resources (water resources, forest products, etc.), on biodiversity, ecosystem services and on plants in general, some positive and on others negative effects, such as, altering biophysical relationship, shrinking of habitats, desertification and general shift in natural world. Warming directly affects rate of plant respiration, photosynthesis, and other biogeochemical processes. For instance, enhanced CO2 concentration can increase photosynthetic rate especially for plants growing under warm and dry condition such as C3 plants. Naturally, plants have their own mechanism to tolerate a certain level of increased temperature. As soil temperature increase, the decomposition rate of organic matter will increase, and then nutrient mineralization and availability for plants uptake become increased at presence of sufficient water if other conditions are unchanged. This Working Paper provides an overview of projected climate change impacts on agriculture, crop growth, production, physiological and biochemical function of plants and suitability across the world.
