    Drought impacts and related risk management by smallholder farmers in developing countries : evidence from Awash River Basin, Ethiopia
    (2010) Zeller, Manfred; Keil, Alwin; Murendo, Conrad
    Climate risk studies have largely neglected household coping and adaptation strategies. In this paper we analyze drought impacts, drought risk management, and resulting drought resilience in Awash River Basin of Ethiopia based on socio-economic data collected from 43 randomly selected Peasant Associations. We find that severe drought periods have led to a significant depression of crop yields and to widespread death of livestock in the past. Drought periods have drastically increased the proportion of food insecure households and lengthened the duration of food insecurity in the area. Since, with climate change, drought periods are predicted to become more frequent in this region in the future, the problem of food insecurity is likely to become even more severe. Ex-ante adaptation strategies are widely practised in Awash River Basin and include the storage of crop residues as fodder for livestock, the rearing of drought tolerant livestock, mixed cropping, the use of short duration crop varieties, and the adoption of soil and water conservation practices. Ex-post coping strategies utilized to manage the consequences of drought include the sale of assets and the reliance on consumption loans and support offered by informal networks. Therefore, suitable policies are urgently needed to strengthen farmers? capacity to adapt to and cope with drought. Training farmers in the production and conservation of livestock fodder as well as in soil and water conservation practices appear to be key policy options relevant in the area. Moreover, improving farmers? access to climate related information, especially drought forecasts, could improve the timely adoption of effective adaptation measures.

    Using panel data to estimate the effect of rainfall shocks on smallholders food security and vulnerability in rural Ethiopia
    (2009) Zeller, Manfred; Demeke, Abera Birhanu
    Ethiopia's agriculture is predominantly rainfed and hence any irregularity in weather conditions has adverse welfare implications. Using panel data, this paper analyzes the effect of rainfall shocks on Ethiopian rural households' food security and vulnerability over time while controlling for a range of other factors. To this end, we generated a time-variant household food security index which is developed by principal components analysis. Based on the scores of the index, households were classified into relative food security groups and their socioeconomic differences were assessed. The exploratory results show that compared to the less secured households, the more secured ones have male and literate household heads, tend to have a greater number of economically active household members, own more livestock, experience better rainfall outcome, participate in equb (a local savings group), and use chemical fertilizer. Fixed effects regression was used to identify the factors which affect the score's variability and the results indicate that rainfall shock is an important factor affecting households' food security over time. It is also noted that household size, head's age, participation in equb, off-farm activities, use of fertilizer, and livestock ownership positively and significantly affect the food security score. Results from multinomial logistic regression model reinforce the fixed effects regression results by showing the strong association of persistent food insecurity and vulnerability with adverse rainfall shock. A number of conclusions can be drawn from the results which are useful for policymakers as well as for agencies that engage in areas of risk and food security.
