Abstract

Abstract Climate change associated with anthropogenic stressors is considered the main threat to these wetlands resulting in reduced water connection followed by a decline in ecological functions. This article presents a systemic approach to assess the present ecological status of a subtropical floodplain wetland concerning the fisheries and associated ecosystem services. The analysis of historic climatic data indicated a weak increasing (R2 = 0.098) and decreasing (R2 = 0.042) trend in average annual air temperature and total annual rainfall, respectively. In addition, a significant reduction in the wetland area was also observed. Altogether, 45 fish species were reported in the studied wetland, of which 2 are listed as endangered and 7 are near threatened. Fish production increased from 2010 to 2020 as a result of culture-based fisheries practice. The present study demonstrated the variation of the important fisheries-related environment and nutrient parameters of the wetland through the geographic information system (GIS)-based spatial distribution map for the reader's digest. It has been found that the provisioning ecosystem services are higher in number (n = 9) followed by supporting (n = 6), regulating (n = 4), and cultural (n = 2) ecosystem services. Finally, we have discussed some important case-specific sustainable climate-smart adaptation and mitigation approaches to strengthen the resilience and adaptive capacity of fishers.

气候变化背景下恒河流域亚热带洪泛平原湿地生态评价

气候变化和人为压力因素是湿地面临的主要威胁，导致湿地水连接减少，生态功能下降。本文提出了一种从渔业和相关生态系统服务功能方面评价亚热带洪泛平原湿地生态现状的系统方法。历史气候资料分析表明，年平均气温呈微弱上升趋势(R2 = 0.098)，年总降雨量呈微弱下降趋势(R2 = 0.042)。此外，湿地面积也明显减少。湿地共录得45种鱼类，其中2种为濒危鱼类，7种为近危鱼类。由于以养殖为基础的渔业实践，鱼类产量从2010年到2020年有所增加。本研究通过基于地理信息系统(GIS)的空间分布图，展示了湿地与渔业相关的重要环境和营养参数的变化，供读者参考。研究发现，提供生态系统服务的数量最多(n = 9)，其次是支持(n = 6)、调节(n = 4)和文化(n = 2)生态系统服务。最后，我们讨论了一些重要的针对具体案例的可持续气候智能型适应和缓解方法，以加强渔民的复原力和适应能力。
