Abstract
Abstract: Climate change is a subset of the larger set of ecosystem change that is promoting the emergence and reemergence of animal diseases. It is disrupting natural eco systems by providing more suitable environments for infectious diseases causing agents to move in to new areas where they may harm wild life and domestic species, as well as humans. Diseases that were previously limited only tropical areas are now spreading to other previously cooler areas. Pathogens that were restricted seasonal weather patterns can invade new areas and find new susceptible species as the climate warms and / or the winter get milder. Occurrence of tropical infectious diseases in the mild latitudes is linked to global warming is increasing. Insect borne diseases are now pin temperate areas where the vector insects were none existent in the past. Animal production facilities will be affected both directly and indirectly by climate change. The direct effects include the interchange of heat between the animal and its environment, associated with temperature, humidity, wind spread and thermal production. These are factors that influence animal performance (growth, milk and wool production, reproduction), as well as animal health and welfare. The indirect effects include the influence of climate on the quantity and quality of fodder crops and grains, and severity and distribution of diseases and parasites. In our country there is huge problem of animal diseases and production decrement due to climate change. Therefore the objectives of the seminar are:- To identify and create awareness on the impacts of climate change on diseases prevalence and to identify and create awareness on the impacts of climate change on animal production
