This study examined land use land cover change and its determinants in Tigray, Ethiopia and its livelihood zones. We used socioeconomic panel, and satellite data, and applied a mixed-effects model to analyse the factors influencing land allocation among different uses, and transition matrix to analyse land cover dynamics. The results revealed that; land use choices were influenced by plot level factors (such as plot elevation, distance, soil type and quality, and land tenure), household characteristics (such as education, dependency ratio, plot size and number owned, income, livestock and asset, perception of climate change, and access to market and main road), and community level factors (precipitation, product price, population density and livelihood zone variations). Transition matrix analysis showed that between 1986 and 2016, 12.8% of forest was converted to bare land, 6.26% bare land was converted to pasture, and 5.84% of cropland was converted to forest. However, net deforestation occurred in most of the livelihood zones. Therefore, local communities faced environmental and socio-economic challenges from capital constraints induced land fallowing, land fragmentation, and unmanaged land cover change. The study recommended sustainable land use planning and management, market linkages, improved access to roads, forestry subsidies, land tenure security, and land consolidation programs.
本研究考察了埃塞俄比亚提格雷及其生计区的土地利用土地覆盖变化及其驱动因素。我们使用了社会经济面板数据和卫星数据,并应用混合效应模型分析影响不同用途土地分配的因素,以及用转移矩阵分析土地覆盖动态。结果表明:土地利用选择受地块层面因素(如地块海拔、距离、土壤类型和质量以及土地保有权)、家庭特征(如教育程度、抚养比、地块规模和拥有数量、收入、牲畜和资产、气候变化认知以及市场和主干道可达性)以及社区层面因素(降水量、产品价格、人口密度和生计区差异)的影响。转移矩阵分析表明,1986年至2016年间,12.8%的森林转变为裸地,6.26%的裸地转变为牧场,5.84%的农田转变为森林。然而,大多数生计区都出现了净森林砍伐。因此,当地社区面临着因资本限制导致的土地休耕、土地碎片化和无管理的土地覆盖变化所带来的环境和社会经济挑战。该研究建议进行可持续土地利用规划和管理、建立市场联系、改善道路可达性、提供林业补贴、保障土地保有权以及实施土地合并计划。
