摘要

本研究评估了 2004-2024 年间合作建房征地对沃尔迪亚镇土地环境的影响。研究采用了卫星图像、谷歌地球专业版、焦点小组讨论、个人观察和关键信息提供者访谈等方法。结果显示,2004-2024 年间,农田比例从 19.27% 降至 6%,森林覆盖率从 24.95% 降至 13.98%,裸地比例从 18.84% 降至 2.37%。在规定年份内,建筑覆盖率从 11.35% 大幅上升至 49.62%。结果进一步表明,由于建筑密集区、垃圾处理不当、人口增长、道路扩张和合作建房扩张,生境质量从 2014 年的 0.79 降至 2024 年的 0.63。栖息地质量状况与栖息地质量评估年数、建筑密集区、垃圾处理、人口密度、道路和合作建房之间呈强烈的负相关,而森林覆盖率则呈强烈的正相关。这些问题可以通过应用分区法、城市规划、紧凑型开发、混合用途开发、推广可持续土地利用方法、保护重要栖息地、制定和实施增加森林覆盖率的政策以及提高公众意识来加以解决。本研究的新颖之处在于绘制了因合作开发住房而征用土地所导致的栖息地质量地图,以帮助实现 2030 年可持续发展的两个目标:目标 11(使城市和人类住区具有包容性、安全性、复原力和可持续性)和目标 15(保护、恢复和促进土地生态系统的可持续利用,以可持续的方式管理森林,阻止土地退化和生物多样性丧失)。研究结果为决策者和规划者可持续地规划和管理土地环境提供了信息。

The impact of land acquisition for cooperative housing development on the land environment in Woldia Town, Ethiopia

This study assesses the impact of land acquisition for cooperative housing development on the land environment in Woldia town from 2004 -2024. Satellite imagery, Google Earth Pro, focus group discussions, personal observation and key informant interviews were used. The results revealed that the proportions of farmland decreased from 19.27 to 6 %, forest cover from 24.95 to 13.98 %, and bare land from 18.84 to 2.37 % for 2004–2024. The built-up increased significantly, from 11.35 to 49.62% during the specified year. The results further indicated that the quality of habitats decreased from 0.79 in 2014 to 0.63 in 2024, due to built-up areas, improper waste disposal, population growth, road expansion, and cooperative housing expansion. Strong negative correlations between habitat quality status and the number of years of habitat quality assessment, built-up areas, waste disposal, population density, roads, and cooperative housing were observed while forest cover showed a strong positive correlation. These problems can be managed through the application of zoning laws, urban planning, compact development, mixed-use development, the promotion of sustainable land use practices, the protection of critical habitats, the development and implementation of policies to increase forest cover, and increasing public awareness. The novel component of this study is the preparation of maps for habitat quality due to land acquisition for cooperative housing development, and to aid in the accomplishment of two 2030 Sustainable Development Goals: goal number 11 (making cities and human settlements inclusive, safe, resilient, and sustainable) and goal number 15 (protecting, restoring, and promoting the sustainable use of land ecosystems, managing forests sustainably, and stopping land degradation and biodiversity loss). The findings inform decision-makers and planners to plan and manage the land environment sustainably.
