“…Higher species diversity with Fisher alpha 12 and Shannon Weiner diversity (H) 3.08 were found in coffee agroforest (Table 3). Previous studies categorized Shannon Weiner diversity as high with a value ≥3, medium with a value between 2 and 3, low with a value between 1 and 2, very low with a value <1 (Atsbha et al, 2019;Fentaw et al, 2022). A Shannon Weiner diversity value of 3.08 of the present study belongs to a high diversity category.…”

The natural forest in southwest Ethiopia is progressively modified to coffee agroforest. To this effect forest composition and diversity is simplified to local preferred coffee shade trees. Woody plant species that are less managed require the conservation priority in coffee agroforest. The study aims at assessing diversity of plant species, investigating local people preference and finally identify woody plants for conservation priority in coffee agroforest in southwest Ethiopia. Data were collected on ecological and ethnoecological information through field assessment and individual interview. Vegetation data were collected from 63 plots distributed across five sites. Ethnoecological data were collected from 96 individuals across five villages living adjacent to the forest through semi-structured interview. The result showed that 48 different woody plant species belonging to 27 families were recorded. Most of the families were represented by single species. The regeneration status of these woody plant species are unsatisfactory or poor. Three species; Cordia africana, Croton macrostachyus, and Milletia ferruginea were accounting for 41 percent of the total number of woody plant species in coffee agroforest. The aggregate relative preference score showed 15 most preferred woody plant species in coffee agroforest. The use value of these species were cited mainly for timber, hanging beehive and beehive making than coffee shade. The findings suggest that 12 woody plants need high conservation priority, 19 species need moderate conservation priority and 17 woody plants need low priority for conservation. The Spearman correlation showed negative correlation between woody plant abundance and conservation priority [rs (46) = −0.681, p = 000]. The study findings suggest that woody plant conservation priority in coffee agroforest should take into consideration local preference of woody plant species.

“…In addition, land use cover and change are very complicated processes that are influenced by a variety of factors (Zheng et al, 2021). Numerous studies on the sustainable evaluation of landscape patterns have utilized the spatial overlap approach, which primarily focuses on separately evaluating various landscape elements and then identifying hotspots while ignoring the trade-offs and synergies among different assessment indicators (Fentaw et al, 2022). This paper proposes an improved technique for assessing ecological sustainability at the local scale in accordance with the SDGs.…”

This study uses AHP-entropy weight methodology and a spatial econometric regression model to evaluate the ecological sustainability and its changes between the current situation and the planning scenario at the 2024 Chengdu International Horticultural Exposition in China. The results reveal that the low and highest sustainability levels decreased, while medium levels increased to 34.04 hm2. Converting village settlements, wastelands, and farmland into exhibition gardens and water bodies will increase medium-level ecological sustainability by improving rain and flood security and reducing flood disaster risk. Integrated Service areas will have more impervious surfaces as the site develops. Some forest destruction, decreased vegetation coverage, three-dimensional green volume, and vegetation carbon stock will result. It will lower the highest ecological sustainability. The regressive correlation between ecological sustainability level and quantitative indicators was relatively high, ranging from 0.5875 to 0.7148. It will provide policymakers with references and guidance for sustainable development mega-events.

“…For instance, Fekadu Hailu et al (2021) evidenced that green legacy has high contribution to mitigating climate change and improving air quality. Also, the research by Fentaw et al (2022) suggested that planting trees and monitoring planted trees enable the improved animal species diversity, abundance, and fresh air. So, green legacy has positive contribution to healthy environment in Ethiopia.…”

A green legacy initiative plays a crucial role in promoting a healthy environment in Ethiopia by restoring ecosystems, mitigating climate change, and fostering environmental awareness and stewardship. Through its tree planting efforts, the initiative aims to create a sustainable and resilient environment that benefits both nature and the people of Ethiopia. The research gap lies in the need for comprehensive studies that assess the impact of the Green Legacy initiative on promoting a healthy environment in Ethiopia. This includes evaluating its impact on biodiversity conservation, soil conservation, and the social and health outcomes of local communities. The mixed research method was employed to have reliable findings on the topic. The regression result was evidenced that tree planting, growing trees for carbon sequestration, biodiversity conservation, soil conservation, community engagement, climate education have positive statistically significant effect on healthy environment in Ethiopia. Based on the research findings, the researchers were forwarded the recommendations for policy makers and government of Ethiopia to take in to consideration the six parameters of green legacy in implementing green legacy incentives in Ethiopia. Addressing these parameters of green legacy will provide a more holistic understanding of the initiative's effectiveness and contribute to evidence-based decision-making for sustainable environmental management in Ethiopia.
