Climate change is a complex problem involving varied interactions between the environment, natural resources (land, crops, animals and water) and peoples. Global climate change poses the threat of serious social upheaval, population displacement, economic hardships and environmental degradation (ESAP, 2009). Agriculture and livestock are amongst the most climate sensitive economic sectors in the developing countries whilst the rural poor communities are more vulnerable to the adverse effects of the climate change (Kimaro and Chibinga, 2013). Climate change may affect livestock disease through several pathways both direct and indirect. It may facilitate establishment of novel imported infectious diseases in regions that were previously unable to support endemic transmissions. Most vector borne diseases that are expected to emerge because of climate change are zoonotic diseases. Climate change may cause amplification of the parasite population and have profound effects on the host-parasite assemblages. Another aspect of climate change is that an effect on the pathogen microorganism by increasing their virulence. Climate change also modify the disease ecology by complicating the life cycles of the different hosts and vectors and the microorganism, that make vector borne diseases difficult to predict and control. Stress caused due to the effect of climate change e.g. increased temperature, increased population density; high density of biting insects or lack of food may induce suppression of the immune response and lead to increased susceptibility of organisms to opportunistic pathogens.
