Livelihood Vulnerability of Semi-Mobile Pastoral Communities to Climate Change in Arid and Semiarid of Iran

Abstract

Climate change is impacting on natural resource based livelihood systems such as pastoralist communities in arid and semi-arid regions. Vulnerability to climate change refers to the potential of a system to be harmed by this external stress. The level of vulnerability of pastoral communities and the effective components determine the extent of climate change impacts on these communities and thereby help identify institutional options that have the potential to reduce their vulnerability. This study assessed climate change vulnerability of semi-mobile pastoralist communities in five main regions (Gozm, Kaht, Madan, Rochon and Jarob) of Khabr rangelands, Kerman, Iran using the Livelihood Vulnerability Index (LVI). The data comprised of primary data on seven main components including socio-demographic profile, livelihood strategies, social networks, health, food, water availability, natural disasters and climate variability which were collected through survey of 70 semi-mobile pastoral households, and secondary data on rainfall and temperature. Data were aggregated using composite LVI index and vulnerabilities of communities were compared. Results suggested that semi-mobile pastoralists in Rochon region had the highest (0.63) LVI showing relatively the greatest vulnerability to climate change impacts in terms of Socio-Demographic Profile, Livelihood Strategies and Health while Kaht region had the least (0.49) LVI showing relatively the smallest vulnerability to climate change impacts. The results of this study are useful to access pastoralist communities’ vulnerability and set risk management policies.
