However, comprehensive assessments of the long-term variations in lakes, marshlands, and terrestrial water storage (TWS) across the TP remain limited. This study utilized a long-term series of Landsat images of the TP to create annual lake maps with 30-m spatial resolution for the period 1990–2022, using a surface water frequency algorithm and Google Earth Engine (GEE). Based on the derived maps, the spatiotemporal trends of marshland area (MA) were analyzed. We also investigated changes in TWS from 2002 to 2022 using GRACE and GRACE-FO data products. Furthermore, we conducted a quantitative analysis of the drivers of changes in lake area (LA) and TWS. Results show that from 1990 to the 2020s, both LA and the number of lakes increased rapidly, with the most pronounced changes occurring in the Inner Plateau. In contrast, MA exhibited a declining trend during 1990–2020, also predominantly in the Inner Plateau. TWS exhibited an overall increasing trend, predominantly occurring in the Inner Plateau, where lakes are most densely distributed—mirroring the spatial pattern of lake expansion. The findings of this study could assist both the government and the general public in confronting the escalating challenges regarding water resources and water security in China.</div></div>","PeriodicalId":101280,"journal":{"name":"Watershed Ecology and the Environment","volume":"7 ","pages":"Pages 274-286"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144212350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study address three challenges in avian population monitoring using optical remote sensing imagery, including high cost of manual annotation, difficulty in extracting small target features in complex background, and insufficient adaptability of multi-scale target recognition. We propose a weakly supervised bird-flock counting method based on the optical image multimodal perception model integrating optical image features and visual semantic features without location annotation. Based on optical image feature enhancement, visual semantic features related to the counting task are extracted through visual cues (counting text prompt), and a learnable feature adapter is introduced to fuse optical image features with visual semantic features. Thus, an optical image multimodal perception model with residual connection mechanism and multi-scale information interaction module is constructed. The residual connection mechanism effectively alleviates the interference caused by posture changes and complex background, and the multi-scale information interaction module solves the problem of target scale change through cross-scale semantic propagation. We construct an optical images bird-flock dataset named Wetland-Bird-Count for the Yellow River Delta coastal wetlands. The experimental results show that the MAE and MSE of the proposed method are 45.2 and 54.2, which is much more accurate than other weakly supervised and unsupervised methods and close to the fully supervised counting method, which verifies that the weakly supervised cluster counting using optical image visual cues can improve the accuracy of bird flock counting under lightweight annotation.

A structured search using PRISMA (preferred reporting items for systematic reviews and <em>meta</em>-analyses) 2020 employed three major academic databases, namely Scopus, PubMed, and Web of Science. A key factor for choosing sources was their connection to Lake, along with being peer-reviewed, verified by institutions, providing real data on ecological or socio-economic impacts, and being written in English. Information was collected and analyzed by categorizing it into key drivers: changes in land use, pollution, and overfishing. Farming near the lake, cattle grazing and drinking, unsustainable brick-making, overgrazing, illegal fishing, inadequate waste management, and urban expansion have been reported. These practices have led to pollution, the spread of water hyacinth and sedges, nutrient loading, eutrophication, decreased dissolved oxygen, deforestation, soil erosion, flooding, and biodiversity loss-all of which endanger aquatic life. Between 1992 and 2022, land-use changes in Babati Town included increases in institutional land (797.2 ha), industrial land (64.7 ha), and agricultural land (691 ha), while forested areas (−705 ha), undeveloped land (−993 ha), and the lake surface (−173 ha) declined. Fish catch weight fell by 88 %, and daily catch rates declined by 90.8 %, with the most severe decline occurring between 1992 and 2002.

Rainfed farming produces 40 % of food grains and supports two-thirds of the livestock population but faces challenges like land degradation, low productivity, and biodiversity loss due to erratic monsoons and extreme weather. Additionally, India’s water scarcity is worsening, with per capita availability expected to reduce from 802 cubic meters in 2022 to 677 cubic meters by 2050. Therefore, to meet the diverse food requirements of the burgeoning population of the country, conservation of natural resources, and improving the living standard of the resource-poor small and marginal farmers is imperative. Integrated watershed management (IWM) has emerged as a climate-smart strategy to address these challenges by enhancing soil and water conservation, agricultural productivity, and livelihoods in dryland systems. This study assesses the impact of IWM on dryland agriculture in India by analyzing various interventions such as <em>in-situ</em> and <em>ex-situ</em> water conservation, soil health management, and the use of modern technologies like remote sensing (RS) and geographic information systems (GIS). The results revealed that the adoption of IWM practices has led to significant improvements in soil moisture retention (20–25 %), soil organic carbon (22–32 %) agricultural productivity (30–45 %), and water use efficiency (15–25 %). Additionally, soil conservation techniques have reduced soil loss and runoff by 25–50 % and 50–60 %, respectively. Furthermore, the cultivation of lemon grass (<em>Cymbopogon flexuosus</em>), anjan grass (<em>Cenchrus ciliaris</em>), and bamboo (<em>Bambusa spp</em>.) could be the nature-based solutions for mitigating the impact of climate change due to their soil binding capacity and carbon sequestration potential. Moreover, this review indicates the potential of fast-growing trees (<em>Melia dubia</em>) under the agroforestry system in enhancing carbon sequestration by &gt;100 % over sole cultivation. These results demonstrate that IWM is a sustainable solution to mitigate the adverse effects of climate change on dryland farming systems and improve rural livelihoods. Further, the study suggests that IWM practices helps to achieve sustainable development goals (SDGs) such as zero hunger, no poverty, and climate action etc., particularly in the face of climate change in water-scarce regions.</div></div>","PeriodicalId":101280,"journal":{"name":"Watershed Ecology and the Environment","volume":"7 ","pages":"Pages 159-177"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143816974","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employed historical remote sensing images and geospatial analysis to examine the dynamics of three significant wetlands (Phewa, Begnas, and Rupa lakes) in the Pokhara Valley of Nepal, which are designated as Ramsar sites. Changes in land use land cover (LULC) and soil erosion within the watersheds of these lakes were also monitored using Landsat images and soil erosion dataset, respectively. Additionally, climatic trends in the Pokhara Valley were analyzed using data from ground-based monitoring stations. The results highlight a notable 11.39 % decline in the surface area of Phewa Lake since 1989, while the surface areas of Begnas and Rupa have remained relatively stable. Changes in LULC show an increase in forest cover (+47 to 64 %) and decrease in croplands (−36 to 59 %) across all watersheds. Urbanization is most pronounced in the Phewa watershed, leading to increased pollution and shoreline encroachment. The decline in cropland may improve water quality by decreasing agricultural runoff. However, soil erosion is most severe in cropland areas, resulting in Phewa lake receiving the highest sediment influx among the three lakes. The lake regions have been experiencing changes in temperature (0.3 °C per decade) and rainfall (insignificant slight increase). Changes in these lakes are primarily driven by watershed dynamics and human activities.
