Résumé partiel
Climate comprises many factors including temperature, rainfall, humidity, winds and altitude that can have both direct and indirect effects on animal production and health. It can also affect the quality and quantity of feedstuffs such as pasture, forage and grain and the severity and distribution of livestock diseases and parasites. Livestock is very critical as source of food and livelihoods in the ASAL areas which are occupied by pastoralists. Animal diseases contribute to poverty globally particularly in the developing world. Climate change might be associated with these diseases. This study investigated associations between livestock disease occurrence and climatic variability/change in a selected location of Kajiado District of Kenya. The broad objective of this study was to establish whether climate variability has any influence on livestock health in Kajiado District. Specific objectives were to determine the community knowledge, attitudes and practices in connection with diseases and climate change in Kajiado District ; to assess prevalence of key livestock diseases in the study area ; determine the trend of climate changes in Kajiado District ; to investigate associations between livestock disease occurrence and climatic variability ; and to recommend appropriate disease management practices and policies to mitigate against livestock diseases associated with climate variability. This study was done in Enkaroni Location, Central division, Kajiado District which is an ASAL area. The area is characterized by frequent droughts due to climatic changes which lead to migration of pastoralists with their livestock. A cross-sectional survey using participatory rural appraisal (PRA), key informant meetings, transect walks and semi structured interviews was carried out. A semi-structured questionnaire was also administered to 177 households to collect data on the effects of climate change on livestock disease outbreaks. Desk-top data on climate (weather elements of temperature, humidity, rainfall, wind direction and speed) for the previous 30 years from five meteorological stations close to the study site (Dagoretti, Magadi, Narok, JKIA and Wilson Airports) was obtained from the Kenya Meteorological Department. Livestock disease data for the previous 10 years was obtained from the Divisional Veterinary Office. The data was processed and analysed using (SPSS) version 16.0 Statistical package. The study found out that humidity and wet bulb temperature had changed over a 30 year period while climate factors within the five stations had variations.
