Watershed management intervention on land use land cover change and food security improvement among smallholder farmers in Qarsa Woreda, East Hararge zone, Ethiopia

Abstract

ABSTRACT Natural resource bases are the basic foundations of food security. However, they are facing problems both in quantity and quality, leading to decreased land productivity and societal issues. Watershed management is the most effective technique for managing and utilising these resources while improving food security. The study evaluated the effectiveness of the watershed management approach using Arc GIS 10.5 to track changes in land use cover for the years 2009, 2014, and 2020 and surveyed 337 households in three different Programmes. The findings showed six land-use land cover areas, where the proportion of farmland and bare land decreased while the proportion of settlements and shrub land increased in the three micro-watersheds. Population pressure and exotic species' invasion were significant factors contributing to the decline in farmland, while a decrease in bare land and an increase in shrub land were the results of successful watershed management interventions. Survey results showed that approximately 93.4% and 84.9% of respondents reported reduced soil erosion and deforestation, respectively. Further, the integrated watershed approach implemented in the area improved water availability, reduced dependency on single crops, and increased off-farm activity. Thus, scaling up an integrated watershed approach can enhance food security and protect natural resources.
