Application of Livelihood Vulnerability Index in Assessing Vulnerability to Climate Change and Variability in Northern Ghana

Abstract

Climate change is impacting on climate dependent activities such as agriculture in Africa and Ghana. The extent of the impact of climate change in agriculture depends on the level of vulnerability or exposure of farmers to these impacts. This study estimates the level of vulnerability of smallholder farmers to climate change and variability in northern Ghana using the Livelihood Vulnerability Index highlighting access to, and utilization of water resources. The approach estimates vulnerabilities in terms of exposure, sensitivity and adaptive capacity. The data is based on a survey of 320 farm households, complemented with secondary data on rainfall and temperature. Results of the study shows that Northern Region is the most exposed region to climate change and variability. Upper West Region is the most sensitive to climate change and variability especially with regards to water stress; and the Upper East Region has the least adaptive capacity. Northern Region is the most vulnerable in terms of the overall livelihood vulnerability index, followed by the Upper East and Upper West regions.
