Climate change and variability adaptation strategies and their implications for household food Security: The case of Basona Worena District, North Shewa zone, Ethiopia

Abstract

The impact of climate change and variability on agriculture and food security is severe in countries that heavily depend on rainfed subsistence agriculture. Examine climate change and variability and determinant factors of adaptation to ensure household food security in Basona Worena District, central highland of Ethiopia. Data were collected from the randomly selected 138 sample households, key informants and National Meteorological Agency. Rainfall and temperature trend and variability were analyzed using the Mann-Kendall test and Precipitation Concentration Index. Household food security was determined using Household Food Insecurity Access Scale and Food Consumption Score. Moreover, Tobit Model was used to examine climate change and variability adaptation options, while ordered logistic regression was employed to examine the contribution of climate change and variability adaptation to household food security status from the food consumption dimension. In the study site, an increasing minimum and maximum temperatures and decreasing and variable annual and spring season rainfalls were observed. The site has experienced recurrent drought for the last 35 years (1981–2016). Farmers were practicing biophysical soil and water conservation technologies, agro-forestry, small scale irrigation, livelihood diversification, and growing of high yielding and drought resistant crop varieties. The study identified that extension advisory services, access to training, farm size, sex, frequency of flood, and access to credit determine farmers’ climate change and variability adaptation options. HFIAS and FCS analysis shows that food insecurity is high in the study site. Household food security status was influenced by climate variability and limited adaptation responses. The study suggests the implementation of feasible soil and water conservation, and livelihood diversification intervention to ensure household food security.
