Farmers' perceptions of land degradation and their investments in land management: a case study in the Central Rift Valley of Ethiopia.

To combat land degradation in the Central Rift Valley (CRV) of Ethiopia, farmers are of crucial importance. If farmers perceive land degradation as a problem, the chance that they invest in land management measures will be enhanced. This study presents farmers’ perceptions of land degradation and their investments in land management, and to what extent the latter are influenced by these perceptions. Water erosion and fertility depletion are taken as main indicators of land degradation, and the results show that farmers perceive an increase in both indicators over the last decade. They are aware of it and consider it as a problem. Nevertheless, farmers’ investments to control water erosion and soil fertility depletion are very limited in the CRV. Results also show that farmers’ awareness of both water erosion and soil fertility decline as a problem is not significantly associated with their investments in land management. Hence, even farmers who perceive land degradation on their fields and are concerned about its increase over the last decade do not significantly invest more in water erosion and soil fertility control measures than farmers who do not perceive these phenomena. Further research is needed to assess which other factors might influence farmers’ investments in land management, especially factors related to socioeconomic characteristics of farm households and plot characteristics which were not addressed by this study.

Impact of improved maize adoption on household food security of maize producing smallholder farmers in Ethiopia

In recent years, maize has gained prominence as an important staple crop in Ethiopia second only to teff in terms of acreage. Most of this is grown by semi-subsistence farm households whose livelihoods are tied to crop production and some livestock keeping. Therefore, an important policy question concerns the impact that the reported maize revolution has had on household food security. This paper answers that question by examining the empirical regularities that explain the adoption of improved maize varieties (IMVs) and how this has impacted household food security in a sample of 2327 maize producing households in 39 districts of Ethiopia. An endogenous switching regression model supported by the dose-response continuous treatment effect method was used to empirically assess the impact of IMV adoption on per capita food consumption expenditure and perceived household food security status. Results show that IMV adoption has a robust and positive impact on per capita food consumption and also significantly increases the probability of a smallholder being in food surplus. The advances in the adoption of improved maize has thus contributed significantly to the food security of maize producing smallholders, confirming the role of crop improvement in contributing to food security of agrarian households.

Land ownership and technology adoption revisited : improved maize varieties in Ethiopia

Highlights • We study whether land rental discourages improved crop variety adoption.• We show in theory that cash-renters are indifferent, but sharecroppers are encouraged.• Empirical results from Ethiopian maize farmers support the above hypotheses.• Results imply improvements in land rental markets can improve farmers’ welfare.
