In this study, an assessment of the land and surface water resources potential of the Becho Plain was conducted. Land suitability for irrigated agriculture was evaluated by considering the Food and Agriculture Organization (FAO) criteria. The land suitability parameters such as soil properties, slope, land use and land cover were used to identify the suitable irrigable land. The analytical hierarchy process was employed to obtain parameter weights, and later the weighted overlay analysis in the geographic information system was employed to obtain the overall suitability of land resources for irrigation. The surface water availability and amount were evaluated by using the calibrated Soil and Water Assessment Tool (SWAT) model. The water requirement of dominant crops was estimated following the FAO procedure and compared with the available water. Nearly 70% of the land area is identified as suitable for surface irrigation, while the remaining 30% of the land area is restricted for irrigation development. The water supply and demand analysis revealed that there is sufficient water available in the Becho Plain for irrigation development. The physically possible irrigation area and diversion sites were also identified. The Becho Plain has ample land and water resources for irrigation development. However, future developments shall also consider downstream water use to implement sustainable irrigation development.

埃塞俄比亚上阿瓦什盆地 Becho 平原的土地适宜性和地表水资源潜力用于灌溉*

在这项研究中，对贝乔平原的土地和地表水资源潜力进行了评估。灌溉农业的土地适宜性通过考虑粮食及农业组织 (FAO) 的标准进行评估。利用土壤性质、坡度、土地利用和土地覆盖等土地适宜性参数来确定适宜的灌溉土地。采用层次分析法得到参数权重，再利用地理信息系统中的加权叠加分析得到土地资源灌溉的整体适宜性。地表水的可用性和数量通过使用校准的土壤和水评估工具 (SWAT) 模型进行评估。主要作物的需水量是按照粮农组织的程序估算的，并与可用水量进行比较。近 70% 的土地面积被确定为适合地表灌溉，而其余 30% 的土地面积被限制用于灌溉开发。供水和需求分析表明，贝乔平原有足够的水可用于灌溉开发。还确定了物理上可能的灌溉区和分流点。贝乔平原拥有充足的土地和水资源可用于灌溉开发。但是，未来的发展还应​​考虑下游用水以实施可持续灌溉发展。供水和需求分析表明，贝乔平原有足够的水可用于灌溉开发。还确定了物理上可能的灌溉区和分流点。贝乔平原拥有充足的土地和水资源可用于灌溉开发。但是，未来的发展还应​​考虑下游用水以实施可持续灌溉发展。供水和需求分析表明，贝乔平原有足够的水可用于灌溉开发。还确定了物理上可能的灌溉区和分流点。贝乔平原拥有充足的土地和水资源可用于灌溉开发。但是，未来的发展还应​​考虑下游用水以实施可持续灌溉发展。
