Ecosystem services provided by wetlands are essential for communities living near wetlands, especially in an underdeveloped semi-arid landscape. The land use land cover changes and ecosystem degradation and water quality change over the past few decades have had immense effects on declining wetland ecosystem services. With the degradation, it is exerting superfluous effects on wetland communities including loss of livelihood, and decline in other wetland services like fishing, aquaculture, fuelwood, fodder, and many more. The present study attempts to assess the changing nature of wetland health, water quality, and declining ecosystem services of Mount Abu wetlands in Rajasthan, India. For assessing the change of wetland extent, we have used the remote sensing-based data for preparation of land use land cover change from 1992 to 2020. The water samples have been collected from the wetland, and different biophysical parameters of the water have been tested in the laboratory. A questionnaire-based household survey has been conducted to understand the perception of the wetland communities on the loss of ecosystem services over three decades. Further, a correlation and cluster assessment has been conducted to understand the degradation of wetland health in the selected wetlands. The study results indicated deteriorating conditions of wetland health and declining ecosystem services in the study area over the time periods. The land use land cover change analysis indicated a decrease in the spatial extent of the wetlands in the study area. Wetland communities are being affected due to the degradation of wetland health. The study recommended executing a wetland management plan for long-term conservation and livelihood management for the Mount Abu wetlands and communities.
湿地提供的生态系统服务对居住在湿地附近的社区至关重要，特别是在欠发达的半干旱地区。过去几十年，土地利用/土地覆盖变化、生态系统退化和水质变化对不断减少的湿地生态系统服务产生了巨大影响。随着退化的发生，它对湿地社区产生了过多的影响，包括生计丧失，以及其他湿地服务（如渔业、水产养殖、薪柴、饲料等）的减少。本研究试图评估印度拉贾斯坦邦阿布山湿地的湿地健康、水质和不断减少的生态系统服务的变化性质。为了评估湿地范围的变化，我们使用了遥感数据，编制了 1992 年至 2020 年的土地利用/土地覆盖变化图。从湿地采集了水样，并在实验室测试了水样的不同生物物理参数。进行了基于问卷调查的家庭调查，以了解湿地社区对过去三十年来生态系统服务丧失的看法。此外，还进行了相关性和聚类评估，以了解选定湿地的湿地健康退化情况。研究结果表明，在研究期间，湿地健康和生态系统服务不断减少。土地利用/土地覆盖变化分析表明，研究区湿地的空间范围有所减少。由于湿地健康的退化，湿地社区受到了影响。研究建议为阿布山湿地及其社区执行湿地管理计划，以进行长期保护和生计管理。
