Abstract

Land suitability analysis of Moringa oleifera tree cultivation is important to enhance its product, as the demand for this tree for medicinal values and food sources is increasing worldwide. Therefore, this study aimed to assess suitable land for Moringa oleifera tree cultivation by using the integration of multi-criteria evaluation with geospatial technologies in the Dhidhessa catchment, western Ethiopia. Five parameters, namely: slope, land use and land cover (LULC), soil texture, land surface temperature, and rainfall data, were used in this study. The land suitability evaluation of Moringa oleifera is classified into three classes as highly suitable, moderately suitable, and not suitable. The results revealed that, about 344.4 km² (12.2%) of the area is categorized into highly suitable, and 2343.7 km² (83%) is moderately suitable for Moringa tree, whereas, 137.2 km² (4.9%) is categorized as not suitable for Moringa oleifera tree cultivation. Hence, based on the finding of the study, we suggested that farmers and other stakeholders can cultivate Moringa oleifera trees in the Dhidhessa catchment.

基于地理空间技术的辣木种植土地适宜性评价——以埃塞俄比亚Abay盆地Dhidhessa流域为例

辣木种植的土地适宜性分析对于提高其产品质量至关重要，因为世界各地对辣木的药用价值和食物来源的需求正在增加。因此，本研究旨在通过将多标准评估与地理空间技术相结合，在埃塞俄比亚西部的Dhidhessa流域评估适合种植辣木的土地。本研究使用了五个参数，即：坡度、土地利用和土地覆盖（LULC）、土壤质地、地表温度和降雨量数据。将辣木的土地适宜性评价分为高度适宜、适度适宜和不适宜三类。结果显示，约344.4该地区的平方公里（12.2%）被归类为高度适宜，2343.7km2（83%）适度适合种植辣木，而137.2km2（4.9%）被归类为不适合种植辣木。因此，根据研究结果，我们建议农民和其他利益相关者可以在Dhidhessa流域种植辣木。
