Modeling Eragrostis tef Zucc and Hordeum vulgare L cropland in response to food insecurity in the Southwestern parts of Ethiopia

Abstract

On a global scale, there is consensus to double food production as a means to address food and nutrition insecurity, yet the capacity of available resources and technologies to gratify the demands of this growing population and the price of agricultural commodities remains uncertain in Sub-Saharan Africa, particularly in Ethiopia. Despite the availability of fertile agricultural land, inappropriate use of that resource leads to reduced agricultural productivity, yet little is known about food insecurity and impacts on commodities in southwestern Ethiopia. This study was aimed at spatial modeling of land suitability evaluation for Eragrostis tef Zucc and Hordeum Vulgare L crops in the Misha district. About 11 variables related to topography, climate, and soil have been considered and resampled to 10 m resolution. The spatial analysis result indicated that, about 33.4% and 21.8% of the total area is found to be highly suitable, about 54% and 63% of the total study area is categorized into moderately suitable for Eragrostis tef Zucc and Hordeum Vulgare L crop cultivation, respectively, whereas 12.7% and 15.3% of the study area is not suitable for the above mentioned crops. The spatial decision support system reflects that Misha has mammoth potential productive lands, which are most likely promised to satisfy the demand for food and raw materials. Therefore, the stakeholders should make hard-nosed efforts on sage land use and adopt exactly the optimum land suitability plans to advance the current cropland resources for maximize yield in a sensational way for the healthier development of the region.
