| description | Assessing land suitability is crucial for sustainable agricultural production. This study focuses on evaluating the suitability of land for irrigated sugarcane cultivation and determining crop water requirements within the Kuraz Irrigation Scheme in Ethiopia. A combination of geographic information system (GIS) and analytical hierarchy process (AHP) tools was used to classify land suitability and support decision-making by considering factors such as soil pH, texture, temperature, rainfall, land use-land cover, and slope. The AquaCrop model was utilized to simulate current and future scenarios for biomass, canopy cover, yield, maximum evapotranspiration, and water productivity of sugarcane crops. The model was calibrated for irrigated sugarcane during the 2015–2016 crop season, revealing that the majority of the study area is highly suitable for sugarcane cultivation. Specifically, 28% of the area was classified as highly suitable, 38% as moderately suitable, 21% as marginally suitable, and 13% as unsuitable. These findings highlight the potential for expanding sugarcane cultivation to boost yields and profitability. However, the study also underscores the need to consider potential environmental impacts, such as water usage and soil degradation from agricultural expansion. Additionally, social factors, including labor practices and the possible displacement of local communities, must be taken into account when expanding sugarcane cultivation. |
