Abstract

Even though the mosaic of different land-use/land-cover types has long contributed to the resilience of socio-ecological production landscapes and seascapes in Ethiopia, recent data indicate that their sustainability is under threat. This study aims to evaluate landscape resilience by adopting a set of indicators for enhancing sustainability in the Gurage socio-ecological production landscape in Ethiopia. The authors employed a toolkit of indicators in the production landscape through a community-based scoring approach (1-5 Likert scale). The information from household surveys, land-use/land-cover analysis, and satellite-based drought incidents assessment was integrated with the ranking analysis to support the evaluations. The results revealed that landscape diversity, ecosystem protection, local governance, and social equity indicators had the highest landscape resilience ranks. In contrast, lower ranks are associated with knowledge, innovation, livelihoods, and well-being indicators. The overall resilience of the Gurage socio-ecological production landscape was estimated to be below average. Thus, strategies that enhance the resilience and sustainability of this socio-ecological landscape are essential. The findings could help draw the attention of policymakers and natural resource managers to building and strengthening the resilience of the landscape. This study demonstrates that indicators could aid in evaluating landscape resilience status along with other ancillary information, particularly in data-sparse regions. Methods of assessing resilience must be creative in such regions, and this paper may inform such efforts. In addition, the study recommends that landscape resilience indicators be improved by reducing subjective matter and including spatial-explicit dimensions for evaluating resilience.

摘要

尽管不同土地利用/土地覆被类型的镶嵌体长期以来一直有助于埃塞俄比亚社会-生态生产景观和海域的弹性,但最近的数据表明,它们的可持续性正受到威胁。本研究旨在通过采用一系列指标来评估景观弹性,以提高埃塞俄比亚古尔加格社会-生态生产景观的可持续性。作者通过基于社区的评分方法(1-5 级李克特量表)在生产景观中采用了一组指标工具包。通过将基于家庭的调查、土地利用/土地覆被分析和基于卫星的干旱事件评估的信息与排名分析相结合,为评估提供了信息。结果表明,景观多样性、生态系统保护、地方治理和社会公平指标的景观弹性排名最高。相比之下,知识、创新、生计和福祉指标的排名较低。古尔加格社会-生态生产景观的整体弹性估计低于平均水平。因此,增强这种社会-生态景观的弹性和可持续性的策略至关重要。研究结果可以帮助政策制定者和自然资源管理者关注构建和加强景观的弹性。本研究表明,指标可以在辅助其他信息的情况下,有助于评估景观弹性状况,尤其是在数据匮乏的地区。在这些地区,评估弹性的方法必须具有创造性,本文可能会为此类努力提供信息。此外,研究建议通过减少主观因素并纳入空间明确的弹性评估维度来改进景观弹性指标。
