In India, 51 % of the net sown area relies on rainfed agriculture, with 40 % of landholdings unirrigated and 13 % partially irrigated. 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 in-situ and ex-situ 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 (Cymbopogon flexuosus), anjan grass (Cenchrus ciliaris), and bamboo (Bambusa spp.) 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 (Melia dubia) under the agroforestry system in enhancing carbon sequestration by >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.
在印度,51%的净播种面积依靠雨养农业,40%的土地没有灌溉,13%的土地只有部分灌溉。雨养农业生产了40%的粮食,养活了三分之二的牲畜,但面临着土地退化、生产力低下和因不稳定的季风和极端天气导致的生物多样性丧失等挑战。此外,印度的水资源短缺正在恶化,人均可用水量预计将从2022年的802立方米减少到2050年的677立方米。因此,为了满足该国不断增长的人口对食物的多样化需求,保护自然资源,提高资源贫乏的小农和边缘农民的生活水平势在必行。综合流域管理(IWM)已成为一项气候智能型战略,通过加强旱地系统的水土保持、农业生产力和生计来应对这些挑战。本研究通过分析各种干预措施,如原位和非原位水土保持、土壤健康管理以及遥感(RS)和地理信息系统(GIS)等现代技术的使用,评估了IWM对印度旱地农业的影响。结果表明,采用IWM措施可显著提高土壤保墒(20 - 25%)、土壤有机碳(22 - 32%)、农业生产力(30 - 45%)和水分利用效率(15 - 25%)。此外,土壤保持技术使土壤流失和径流分别减少了25 - 50%和50 - 60%。此外,种植柠檬草(Cymbopogon flexuosus)、冬青草(Cenchrus ciliaris)和竹子(Bambusa spp.)可能是缓解气候变化影响的自然解决方案,因为它们具有土壤结合能力和碳固存潜力。此外,本综述还指出,在农林复合系统下,速生乔木(Melia dubia)的固碳潜力比单独种植提高100%。这些结果表明,IWM是缓解气候变化对旱地农业系统不利影响和改善农村生计的可持续解决方案。此外,研究表明,IWM实践有助于实现可持续发展目标(sdg),如零饥饿、无贫困和气候行动等,特别是在缺水地区面临气候变化的情况下。

Understanding hydrochemistry and diatom assemblage is important for assessing the health of aquatic ecosystems. This study has analyzed the water quality and diatom communities in the Dordi River, which is one of the major tributaries of the Marsyangdi River in Nepal. The primary research question being addressed in the study was what is the state of water quality parameters of Dordi River and how do they relate to the distribution and composition of diatoms. The water quality parameters of the river like temperature, pH, electric conductivity (EC), total dissolved solids (TDS), dissolved oxygen (DO), turbidity, and total alkalinity (TA) were measured in-situ, whereas concentrations of major ions (Ca2+, Mg2+, K+, Na+, NH4+, HCO3, Cl, SO42–, NO3, and PO43–), biological oxygen demand (BOD) and chemical oxygen demand (COD) were analyzed in the laboratory by collecting water samples from different parts of the river. Piper plot, Gibbs plot, Mixing plots, redundancy analysis, and principal component analysis were applied for evaluating the spatial variation of anions and cations in water. The results showed alkaline water following the pattern: Ca2+>Mg2+>Na+>K+>NH4+ for cation and HCO3>Cl>SO42–>PO43–>NO3 for anion with calcium-bicarbonate dominant lithology in the river. Overall, the results highlight that the drinking and irrigation water qualities of the river were found to be excellent. Additionally, among 75 diatom species observed in the samples, the Bacillariophyceae was the dominant class covering 92% of the species. The results indicated that the diatom species richness declined as elevation increased. The distribution of diatoms was also influenced by the land use types near the water sampling points, tributaries and the main river. Overall, the physico-chemical quality of water showed significant influence on diatom species composition. The findings of this study could be useful for understanding hydrochemistry and association of water quality and diatoms in river basins of the Himalaya.
了解水化学和硅藻组合对评估水生生态系统的健康具有重要意义。本研究分析了尼泊尔马尔尚底河主要支流之一的多迪河的水质和硅藻群落。本研究的主要研究问题是Dordi河的水质参数是什么状态,以及它们与硅藻的分布和组成有何关系。现场测量了温度、pH、电导率(EC)、总溶解固形物(TDS)、溶解氧(DO)、浊度和总碱度(TA)等水质参数,并在实验室采集了不同河段的水样,分析了主要离子(Ca2+、Mg2+、K+、Na+、NH4+、HCO3 -、Cl -、SO42 -、NO3 -和PO43 -)浓度、生物需氧量(BOD)和化学需氧量(COD)。采用Piper图、Gibbs图、混合图、冗余分析和主成分分析评价了水体中阴离子和阳离子的空间变化。结果表明,该河流碱性水具有Ca2+>;Mg2+>Na+>K+>;阳离子为NH4+,阴离子为HCO3 - >;Cl - >SO42 - >PO43 - >NO3 -,碳酸氢钙为主岩性。总体而言,结果突出表明,该河流的饮用和灌溉水质优良。此外,在75种硅藻中,硅藻门为优势纲,占总数的92%。结果表明,随着海拔的升高,硅藻物种丰富度呈下降趋势。水样点、支流和干流附近的土地利用类型对硅藻的分布也有影响。总体而言,水体理化质量对硅藻种类组成有显著影响。本研究结果对了解喜玛拉雅山流域水化学及水质与硅藻的关系具有重要意义。

The morphology, distribution, and structural control of karst closed depressions in a dolomitic karst landscape are the focus of this study. The study area is the Jbel Dersa Massif (JDM), part of the “Dorsale Calcaire” (DC) unit within the Rif Mountain range in northern Morocco. A combined analysis of geomorphological mapping and structural studies reveal that the Pliocene dismantling phase smoothed the crests of the original imbricate thrust fronts, characteristic feature of the DC unit’s structure. The flattening of the massif’s summit facilitated the dissolution of the rock surface. In addition to the massif’s ruiniform landscape, the observed karstic features include fracture lapies, closed karstic depressions at the summit, and travertine deposits along the structural contacts with the bordering non-karstic units. The 26 identified closed depressions are dissolution dolines. Morphometric analysis indicates that these dolines are primarily located in the endorheic and axial zones of the massif and are preferentially aligned along tectonic faults. Structural, geomorphological, and ERT profile analyses of two sinkholes confirm the structural control over their development and demonstrate that seepage occurs through the fractured material along fault planes. This study highlights the scientific, environmental, and water-supply significance of the JDM. Its karst depressions, serving as primary infiltration zones, play a crucial role in local hydrogeology, providing water sources for several settlements that rely on the massif’s springs.
本文重点研究了白云岩岩溶封闭性洼地的形态、分布及构造控制。研究区域是Jbel Dersa地块(JDM),是摩洛哥北部Rif山脉“Dorsale Calcaire”(DC)单元的一部分。地貌填图与构造研究相结合表明,上新世的拆拆阶段使原始叠瓦状冲断前缘的波峰变得平滑,这是直流单元构造的特征。山体顶部的变平促进了岩石表面的溶解。除了该地块的废墟状景观外,观察到的岩溶特征还包括断裂带、峰顶闭合岩溶洼地以及沿与周边非岩溶单元构造接触的钙华矿床。确定的26个封闭凹陷为溶蚀凹陷。形态计量学分析表明,这些白云线主要分布在地块的内海带和轴向带,并优先沿构造断裂排列。两个陷坑的构造、地貌和ERT剖面分析证实了构造对其发育的控制作用,并表明沿断层面的裂隙物质发生渗流。这项研究突出了JDM的科学、环境和供水意义。它的喀斯特洼地作为主要的入渗区,在当地的水文地质中起着至关重要的作用,为依赖该地块泉水的几个定居点提供了水源。

Water resources management is fundamental to the sustainability of river basins. Water quality is affected by pollution caused by human activities. In this context, the restoration of degraded watersheds helps soil recovery, sustainable water management, reforestation, biodiversity conservation and mitigation of human impacts. Artificial intelligence (AI) innovates data management and analysis processes by optimising decision-making and data analysis in hydrological studies and ecological restoration. This research aims to analyse scientific information related to the integration of AI in studies on hydrogeology and ecological restoration of watersheds by analysing scientific databases for knowledge of the intellectual structure, lines and trends of research. The methodology includes three phases: i) search criteria and data processing (Scopus-Web of Science); ii) analysis of the intellectual and conceptual structure; and iii) application of the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) method. The results indicate that there is a total of 171 records, with a 4.49% growth in scientific production in the last four years, focusing on artificial neural networks (10.53%), artificial intelligence (3.51%), genetic algorithms (1.17%) and machine learning (1.17%). This increase is due to the climatic variation generated in recent years, driven by anthropogenic pressures, especially in the agricultural sector due to the high demand for fertiliser and pesticide pollution. This problem has prompted the search for more far-reaching environmental management technologies, making it a potential niche for study. China (72.51%) and the United States (25.73%) are the most outstanding contributors to production in this area. On the other hand, there is less research in this area in developing countries such as South Africa (2.92%), Colombia (1.17%), and Argentina (0.58%), among others. This analysis identifies opportunities and challenges in applying AI for water resource optimisation and water quality prediction, providing an innovative conceptual framework for sustainable watershed management.
水资源管理是河流流域可持续发展的基础。水质受到人类活动污染的影响。在这方面,恢复退化的流域有助于土壤恢复、可持续水资源管理、重新造林、生物多样性保护和减轻人类影响。人工智能(AI)通过优化水文研究和生态恢复中的决策和数据分析,创新数据管理和分析过程。本研究旨在通过分析科学数据库的知识结构、研究方向和趋势,分析与人工智能在水文地质与流域生态恢复研究中的整合相关的科学信息。该方法包括三个阶段:i)搜索标准和数据处理(Scopus-Web of Science);Ii)智力和概念结构分析;iii)应用系统评价和荟萃分析(PRISMA)方法的首选报告项目。结果表明,共有171项记录,近四年科学产出增长4.49%,主要集中在人工神经网络(10.53%)、人工智能(3.51%)、遗传算法(1.17%)和机器学习(1.17%)。这种增加是由于近年来人为压力造成的气候变化,特别是在农业部门,由于对化肥和农药污染的高需求。这一问题促使人们寻求影响更深远的环境管理技术,使其成为一个潜在的研究领域。中国(72.51%)和美国(25.73%)是该地区产量贡献最突出的国家。另一方面,发展中国家在这方面的研究较少,如南非(2.92%)、哥伦比亚(1.17%)和阿根廷(0.58%)等。该分析确定了将人工智能应用于水资源优化和水质预测的机遇和挑战,为可持续流域管理提供了创新的概念框架。

Ecological Regulation and Storage (ERS), a crucial natural regulatory mechanism in river basins, is vital in assessing watershed resilience and guiding water resource management. This study establishes a novel tripartite framework (vegetation-wetland-soil) to quantify ERS dynamics in the ecologically fragile Source Region of the Yangtze and Yellow Rivers (SRYY). Integrating multi-source hydrological data (2000–2020) with improved modeling approaches, including a modified SCS-CN method incorporating organic matter dynamics and NDVI-driven vegetation modules, we reveal three key insights: (1) Total ERS exhibited a distinct V-shaped trajectory during 2000–2020, underscoring the system’s resilience and recovery potential; (2) Wetland regulation dominated temporal fluctuations, followed by soil regulation, while canopy interception and litter retention functioned as stabilizing components; (3) Vegetation regulation displayed pronounced seasonal variability, with a robust positive correlation between canopy interception and litter retention (r = 0.94, p = 0.019), revealing synergistic hydrological coordination within the vegetation layer.
生态调节与蓄水(ERS)是一种重要的流域自然调节机制,在评价流域恢复力和指导水资源管理方面具有重要意义。本研究建立了植被-湿地-土壤三方框架来量化长江黄河生态脆弱源区ERS动态。综合多源水文数据(2000-2020年)和改进的建模方法,包括改进的SCS-CN方法,包括有机质动力学和ndvi驱动的植被模块,我们发现了三个关键见解:(1)2000-2020年期间,总ERS呈现出明显的v型轨迹,强调了系统的弹性和恢复潜力;(2)湿地调控主导时间波动,土壤调控次之,冠层截留和凋落物滞留是稳定因子;(3)植被调节表现出明显的季节变异性,冠层截留与凋落物滞留呈显著正相关(r = 0.94, p = 0.019),揭示了植被层内部的协同水文协调作用。

Sustainable land management is necessary for soil erosion control, vegetation recovery, and land restoration. This study was conducted to identify the soil erosion susceptibility areas in the Winike watershed, upper Omo Gibe Basin of Ethiopia. Analytic Hierarchy Process (AHP) and InVEST modeling combined with GIS were used to generate primary data on soil erosion severity. Land use types, slope, elevation, NDVI, rainfall, drainage density, and soil types were important variables analyzed for soil erosion rate determination. The result shows a significant variation in soil erosion vulnerability among sub-watersheds ranging from low to very high vulnerability. The watershed’s very highly vulnerable eastern part accounts for 108.23 km2 (9.91 %) due to lacks vegetation cover, while the less vulnerable to the western part covers 179.66 km2 (16.46 %). Analysis of the Geo-environmental parameters shows that rainfall (26 %) is the most significant influencing factor, followed by vegetation cover (i.e., land use types), explaining about 23 % of the erosion severity. Comparing soil erosion vulnerability using the AHP and InVEST SDR models was 14.01 % and 16 %, respectively, suggesting insignificant variation between the erosion vulnerability analysis models. The study emphasizes the usefulness of erosion vulnerability modeling for identifying investment priority areas based on soil erosion status for soil conservation intervention, offering a range of decision-making options for land management.
可持续的土地管理是控制水土流失、植被恢复和土地恢复的必要条件。对埃塞俄比亚Omo Gibe盆地上游Winike流域土壤侵蚀易感区进行了研究。利用层次分析法(AHP)和InVEST模型与GIS相结合,生成土壤侵蚀严重程度的原始数据。土地利用类型、坡度、高程、NDVI、降雨量、排水密度和土壤类型是确定土壤侵蚀速率的重要变量。结果表明,各流域土壤侵蚀脆弱性存在着从低到高的显著差异。流域东部由于缺乏植被覆盖,高度脆弱区面积为108.23 km2(9.91%),而西部相对脆弱区面积为179.66 km2(16.46%)。地质环境参数分析表明,降雨(26%)是最重要的影响因素,其次是植被覆盖(即土地利用类型),解释了约23%的侵蚀严重程度。AHP模型和InVEST SDR模型对土壤侵蚀脆弱性的比较分别为14.01%和16%,表明侵蚀脆弱性分析模型之间差异不显著。该研究强调了侵蚀脆弱性模型在确定土壤保持干预的投资重点区域方面的作用,为土地管理提供了一系列决策选择。

Recreational, agricultural, and industrial utilizations of areas surrounding waterways provide opportunities for collecting chemical and pollutant runoff, which influence the chemical makeup of the waterways and connecting watersheds. Human activities within watersheds can result in conditions that enable pathogenic microorganisms to thrive and allow unique microbial communities to emerge. The study area consisted of three locations at the Blue.
Marsh Watershed in Reading, Pennsylvania, with different surrounding land use and anthropogenic activities. The study areas were monitored monthly during the five-year project to assess seasonal variations in chemical levels and microbial count changes.
Chemical testing included inorganic nitrates, inorganic phosphates, and dissolved oxygen. Additional microbial testing included monthly counts for Escherichia coli and Enterococcus spp. to assess potential pathogenic microbial populations. On most occasions, chemical analyses found nitrate and phosphate concentrations above natural environmental levels.
During the five years, Escherichia coli and Enterococcus spp. concentrations were above the EPA recreational water recommendations 52% and 83% of the time, respectively. These results suggest that recreational, agricultural, and industrial utilization of surrounding waterways may influence chemical and microbial characteristics, including pathogenic microorganisms in the Blue Marsh Watershed.
水道周围地区的娱乐、农业和工业利用为收集化学和污染物径流提供了机会,这些径流影响了水道和连接流域的化学组成。流域内的人类活动可造成条件,使病原微生物得以茁壮成长,并使独特的微生物群落得以出现。研究区域包括Blue的三个地点。宾夕法尼亚州雷丁的沼泽流域,周围不同的土地利用和人为活动。在为期五年的项目中,每个月对研究区域进行监测,以评估化学水平和微生物数量变化的季节性变化。化学测试包括无机硝酸盐、无机磷酸盐和溶解氧。其他微生物检测包括每月大肠杆菌和肠球菌计数,以评估潜在的致病微生物种群。在大多数情况下,化学分析发现硝酸盐和磷酸盐的浓度高于自然环境水平。在5年的时间里,大肠杆菌和肠球菌浓度分别有52%和83%的时间高于EPA的娱乐用水建议值。这些结果表明,周边水道的娱乐、农业和工业利用可能会影响蓝沼泽流域的化学和微生物特征,包括病原微生物。

As global waste production grows, sustainable waste management (WM) has become an issue for modern societies. This paper explores the integration of Artificial Intelligence (AI), particularly Machine Learning (ML) and Deep Learning (DL), to improve waste management (WM) systems by enhancing automation, classification accuracy, operational efficiency, and real-time decision-making. Current trends and potential future directions are identified with bibliometric and scientometric analysis, which assess methodologies and data in the field. By automating processes such as waste classification, sorting, and transportation, AI-driven models have the potential to optimize operational efficiency and reduce environmental impact. A comprehensive review of recent AI research in WM is presented, with a focus on their effectiveness, scalability, and limitations. Moreover, in the proposed framework, the data augmentation approach has been utilized to improve the model’s performance by increasing the amount of samples. Furthermore, the MobileNetV3 DL model is employed for feature extraction. Besides, the feature selection method − Harris Hawk Optimization (HHO) is also utilized to choose the best subset of features and reduce the irrelevant features. Then these selected features are fed into Machine Learning algorithms such as Decision Tree (DT), Logistic Regression (LR), and Random Forest (RF). In summary, this review highlights key case studies and research insights, offering a roadmap for future developments in AI-driven WM solutions.

This study highlights the importance of rice paddies in snow-rich regions of central Japan as habitat for wetland bird species during snow-melting late winter season. During the study period, we recorded seven wetland species, including waders, egrets, and waterfowls. The abundance and richness of these birds were not significantly associated with the patch size of rice paddies. However, bird abundance presented a marginally positive association with the coverage of open water bodies within the landscape, while species richness showed a marginal relationship with the distance to the nearest water body. Our findings suggest that snowmelt-created wetlands may provide functions as critical stopover sites for migratory birds along the East Asian-Australian Flyway, and that enhancing water features in agricultural landscapes may yield greater conservation benefits than simply modifying the patch size of agricultural wetlands.
本研究强调了日本中部富雪地区稻田在冬末融雪期间作为湿地鸟类栖息地的重要性。在研究期间,我们记录了涉禽、白鹭、水禽等7种湿地物种。这些鸟类的丰度和丰富度与稻田斑块大小无显著相关。然而,鸟类丰度与景观内开放水体的覆盖度呈边际正相关,而物种丰富度与最近水体的距离呈边际相关。我们的研究结果表明,融雪形成的湿地可能为东亚-澳大利亚迁徙路线上的候鸟提供了重要的中途停留点,并且增强农业景观中的水景可能比简单地改变农业湿地的斑块大小产生更大的保护效益。

This review of the scientific literature on mangrove management systems using bibliometric methods aimed to identify research trends, key topics, and collaboration between researchers. Data were collected from a one-time search of the Scopus database over the last ten-year period (2014– 2023). Bibliometric analysis was conducted using Microsoft Excel, OpenRefine, RStudio, Tableau, and VOSviewer to visualize keyword networks, publication trends, and research collaboration. The study showed a significant increase in publications related to mangrove management systems in the last decade. The most frequently discussed topics included global analysis, restoration, climate mitigation, ecosystem services, and blue carbon. The collaboration network showed extensive international cooperation, especially between researchers from Australia and Southeast Asia. The analysis revealed gaps in the coverage of key research areas in mangrove management systems, particularly in addressing long-term sustainability and effective stakeholder collaboration, such as the need for a multidisciplinary and collaborative approach involving various stakeholders, including local communities, governments, scientists, and sustainable management approaches.
