TEMPORAL AND SPATİAL ANALYSİS OF RİSKY SİTES FOR LİVESTOCK PRODUCTİON İN SOMALİA

Abstract

Temperature stress usually occurs in hot-humid areas, especially in the hot summer months. The increase in the relative humidity with the environmental temperature outside the normal limits adversely affects the well-being and productivity of farm animals. The temperature-humidity index (THI) is employed as a generic criterion in determining temperature stress in this research. This research used GIS and THI techniques to determine suitable locations in Somalia for creating cattle and agricultural sheep production following regulatory and technical standards. Several geostatistical techniques, including deterministic methods (Inverse Distance Weight (IDW) and Radial Based Methods (RBF)) and stochastic (Ordinary kriging (OK) and Co-kriging) (CoK), were used to produce THI maps for Somalia in the GIS environment. Twelve monthly THI maps were obtained, and the geostatistical approach with the minor inaccuracy for each month was chosen, as well as the relevant prospective livestock regions. According to the findings, THI values exceed the danger limit (THI = 79) in March, April, May, June, July, August, and September. Therefore, to prevent the adverse effects of temperature stress, some strategies should be followed between March and September in areas with high THI values, such as the construction of shading areas and animals' feeding times during cooler periods.
