ABSTRACT

The objectives of the study are to identify LULC types that have undergone changes due to quality coffee production and assess smallholders’ perceptions of the LULC changes associated with their coffee production practices in Yirgacheffe coffee area, southern Ethiopia. The study used Landsat satellite images of 1988, 2003, and 2018 to examine the LULC change. In addition, household surveys and focus group discussions were carried out to assess land management practices in the study area. The findings show that forest coffee (FC) cover decreased at a rate of 1.02% per year in the 30-year time, which was mostly changed to semi-forest and semi-plantation coffee cover. The study area has also experienced an increase in semi-plantation cover (0.07% per year), semi-forest coffee (0.9% per year) over the study period, showing a gradual decrease in vegetation cover. This also suggests that a major driving force for the local LULC change is the increasing demand for coffee in the global and national market, as evident from the increasing trend of coffee export from Ethiopia. Survey data show that quality coffee production drives coffee agroforest conversion while it has potitive effects on land management practices by smallholders. Reducing the current heavy dependence of livelihoods on coffee as the single most important commodity is likely to enhance sustainability of the coffee agroforests in the area.

摘要

这项研究的目的是确定由于优质咖啡生产而发生了变化的LULC类型，并评估小农对埃塞俄比亚南部伊尔加切夫咖啡地区与他们的咖啡生产实践相关的LULC变化的看法。该研究使用1988年，2003年和2018年的Landsat卫星图像检查了LULC的变化。此外，还进行了住户调查和焦点小组讨论，以评估研究区域的土地管理做法。研究结果表明，在30年的时间里，森林咖啡（FC）的覆盖率以每年1.02％的速度下降，其中大部分已更改为半森林和半种植咖啡覆盖率。在研究期间，研究区域的半种植面积（每年0.07％），半森林咖啡（每年0.9％）也有所增加，植被覆盖度逐渐降低。这也表明，当地LULC变更的主要推动力是全球和国家市场对咖啡的需求增加，这从埃塞俄比亚咖啡出口的增长趋势中可以明显看出。调查数据表明，优质咖啡的生产推动了咖啡农林的转化，同时对小农的土地管理做法产生了积极影响。减少目前对咖啡的最重要单一商品生计的依赖，可能会增强该地区咖啡农林的可持续性。调查数据表明，优质咖啡的生产推动了咖啡农林的转化，同时对小农的土地管理做法产生了积极影响。减少目前对咖啡的最重要单一商品生计的依赖，可能会增强该地区咖啡农林的可持续性。调查数据表明，优质咖啡的生产推动了咖啡农林的转化，同时对小农的土地管理做法产生了积极影响。减少目前对咖啡的最重要单一商品生计的依赖，可能会增强该地区咖啡农林的可持续性。
