为了保持多样性和可持续性，需要制定战略，以对抗目前家庭菜园农林系统的同质化趋势。这项研究的目的是绘制和描述以Enset为基础的传统家庭花园农林，以管理埃塞俄比亚Gurage社会生态景观的可持续性。我们从正射影像中生成了地块和土地利用土地覆盖(LULC)空间数据，并收集了该地区的住户调查数据。通过对家庭花园的组成、功能结构和农业生态区的整合，明确了五种家庭花园类型。大多数家庭花园类型都有类似的水平功能结构，多年生作物种植在宅基地附近，一年生作物种植在外田，林地位于地块的末端。不同的木本植物种类、作物品种和地块大小在单个家庭地块中被确定，这些在家庭花园类型中是不同的。由于社会经济变化和缺乏技术投入，埃塞俄比亚境内以Enset为基础的家庭菜园农林生产一直在下降。这些挑战可能会损害社区的粮食安全，丧失家庭菜园系统提供的产品多样性。因此，有必要根据家庭花园类型采用技术和扩大农林做法，以便继续提供多种捐助。这项研究展示了农林复合系统特定地点的空间特征，考虑了一种整体方法，以减少当地的挑战，并支持在不断变化的社会生态景观中发展可持续景观管理。
Developing strategies that counter the ongoing homogenization trends of home-garden agroforestry systems is required to maintain diversity and sustainability. This study aimed to map and characterize traditional enset-based home-garden agroforestry for managing sustainability in the Gurage socioecological landscape in Ethiopia. We generated plots and land use land cover (LULC) spatial data from orthophotomosaic and collected household survey data of the field. Five home-garden types were identified explicitly through integrating the home-garden composition, functional structure, and agroecological zones. Most home-garden types had similar horizontal functional structures in which perennial crops were planted close to homesteads, annual crops grew in outer fields, and woodlots were located at the end of the parcel. Diverse woody species, crop varieties, and plot sizes were identified in individual household parcels, and these varied across the home-garden types. Enset-based home-garden agroforestry production has been declining in the Ethiopian landscape because of socioeconomic changes and a lack of technological inputs. These challenges may compromise the community’s food security with loss of the product diversity provided by the home-garden system. Thus, technological adoptions and scaling up of agroforestry practices according to the home-garden types are necessary for the continue provision of multiple contributions. This study demonstrated site-specific spatial characterization of the agroforestry systems by considering a holistic approach to reduce the local challenges and support the development of sustainable landscape management in an altering socioecological landscape.
