Abstract

This study assessed the impact of human activities on deforestation and sustainability of water resources and livelihoods in the Congo Basin. It mainly aimed to assess forest degradation in the Yoko reserve from 1976 to 2015 and investigate the compatibility of Landsat imagery for forest monitoring. Digital Image processing for unsupervised classification was done using ENVI software while supervised classification was done by means of ArcGIS 10. Results show that forest landscape faced large scale human induced fragmentation over the last 40 years. If these trends continue, they will affect the sustainability of water resources and livelihoods in the Congo Basin of the Democratic Republic of Congo. Hence, policy makers need to look at key drivers and address impacts that may threaten the future of Hydrological Ecosystems Services, including water and land resources in the Congo Basin. Authorities have to apply an Integrated Management of Water, Land and Ecosystems.

刚果民主共和国基桑加尼洋子森林景观破碎化的多时相Landsat遥感分析

本研究评估了人类活动对刚果盆地森林砍伐、水资源可持续性和生计的影响。主要目的是评估1976 - 2015年阳子保护区森林退化情况，探讨Landsat影像与森林监测的兼容性。使用ENVI软件进行无监督分类的数字图像处理，使用ArcGIS 10软件进行有监督分类。结果表明:近40 a森林景观面临着大规模人为破碎化。如果这些趋势继续下去，它们将影响刚果民主共和国刚果盆地水资源的可持续性和生计。因此，政策制定者需要关注关键驱动因素，并解决可能威胁水文生态系统服务未来的影响，包括刚果盆地的水资源和土地资源。当局必须实行水、土地和生态系统的综合管理。
