Environmental degradation and climate change are no longer just ecological concerns; they have transformed into direct, systemic threats to human security. Traditional frameworks often view environmental issues through a scientific or macroeconomic lens. However, a human security paradigm shifts the focus entirely to the vulnerability of individuals and communities. As global temperatures rise, the compounding effects of severe droughts, catastrophic flooding, and accelerating biodiversity loss are actively destabilizing the foundational pillars of human survival. This paper explores the multifaceted pathways through which environmental disruption undermines human security, focusing empirically on the hard-rock aquifer zones of South India. Integrating decadal remote sensing data (2016–2026) with a field survey of \\(N = 450\\) agrarian households, this study examines how climate-induced resource scarcity triggers acute food and water insecurity, drives unprecedented patterns of forced migration, and introduces novel public health crises. Our results indicate a severe hydro-social crisis: average operational borewell depths plummeted from 450 to 1,150 feet, yielding a 78.4% primary borewell failure rate and forcing a 64.2% permanent out-migration rate to regional megacities, where 91.5% of displaced individuals were absorbed into the low-wage informal labor market. Multivariate logistic regression demonstrates that crop failure frequencies (\\(p \u003C 0.001\\)) and borewell-induced debt (\\(p \u003C 0.001\\)) serve as the strongest structural predictors of household displacement. Ultimately, this study argues that safeguarding human security in the 21st century requires a critical shift from reactive crisis management to proactive, decentralized environmental governance, crop diversification, and resilient sub-surface infrastructure development.

= 450\\)户农业家庭的实地调查相结合，考察气候引发的资源稀缺如何触发严重的粮食与水不安全、驱动前所未有的被迫迁移模式，并引入新型公共卫生危机。研究结果表明存在严重的水—社会危机：平均运行钻井深度从450英尺骤降至1,150英尺，导致78.4%的初级钻井失败率，并迫使64.2%的永久外迁率流向区域大城市，其中91.5%的迁移人口被低工资非正规劳动力市场吸收。多变量逻辑回归表明，作物歉收频率（\\(p \u003C 0.001\\)）和钻井引发的债务（\\(p \u003C 0.001\\)）是家庭迁移最强的结构性预测因子。最终，本研究认为，保障21世纪的人类安全需要从被动危机管理向主动、分散化的环境治理、作物多样化及具有韧性的地下基础设施建设进行关键性转变。关键词：人类安全，环境安全，气候脆弱性，威胁倍增器，资源稀缺，气候诱发迁移，地下水治理，南印度。",null,"International

the relationship between sustainable management of agricultural water resources and farm productivity in Uzbekistan from an agro-management perspective. Agriculture in the country is significantly dependent on irrigation water, and climate change, limited water resources, aging irrigation infrastructure, rising energy costs, and increasing demand for water make water management a strategic issue. The aim of the study is to identify the economic opportunities for increasing water use efficiency, the impact of modern irrigation technologies on farm productivity, and the main constraints to their implementation. The study was conducted based on a systematic narrative literature review. It analyzed international and institutional sources on water management, irrigation efficiency, climate-adapted agriculture, digital technologies, and agroeconomics. The results show that irrigation planning, drip irrigation, canal modernization, land leveling, soil moisture monitoring, remote sensing, and digital management systems can improve water use efficiency. However, the implementation of these technologies is limited by high initial investment, limited financial resources, lack of technical knowledge, infrastructure problems, and insufficient institutional coordination in water management. The study concluded that sustainable water management in Uzbekistan requires, in addition to technological solutions, training farmers, improving financial mechanisms, developing digital information systems, and strengthening cooperation between water management institutions.","本文从农业管理视角分析乌兹别克斯坦农业水资源可持续管理与农场生产力之间的关系。该国农业高度依赖灌溉用水，而气候变化、水资源有限、灌溉基础设施老化、能源成本上升以及用水需求不断增加，使水资源管理成为战略性问题。本研究旨在识别提高水资源利用效率的经济机遇、现代灌溉技术对农场生产力的影响及其推广实施的主要制约因素。研究基于系统性叙述性文献综述开展，分析了有关水资源管理、灌溉效率、气候适应性农业、数字技术和农业经济学的国际与机构来源资料。结果表明，灌溉规划、滴灌、渠道现代化、土地平整、土壤湿度监测、遥感以及数字化管理系统可以提高水资源利用效率。然而，这些技术的实施受到高额初始投资、资金有限、技术知识缺乏、基础设施问题以及水资源管理领域制度协调不足的制约。研究得出结论，乌兹别克斯坦实现可持续水资源管理，除技术解决方案外，还需要培训农民、完善金融机制、发展数字信息系统，并加强水资源管理机构之间的合作。","Zenodo (CERN European Organization for Nuclear Research)","2026-10-07T00:00:00Z",70,{"impact":167,"substance":17,"depth":290,"authority":243,"freshness":20,"relevant":21,"comment":291},15,"系统综述揭示乌兹别克斯坦农业节水与数字灌溉技术的经济可行性与制度约束，对中亚农业信息化有参考价值，但非国内三农核心议题。",[293],{"name":286,"url":283},[295,26,296,297,298],"数字农业","智慧灌溉","节水农业","乌兹别克斯坦",{"code":300,"slug":301,"name":302,"path":303,"parent_code":36},"H3","irrigation","水资源与灌溉","\u002Ftopic\u002Fenvironment\u002Firrigation",[305],{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},{"status":39,"locked":14,"version":40,"method":41,"evidence":307},{"candidates":308,"agricultural_evidence":45},[309,315,320,324,331],{"code":300,"score":126,"supported":45,"title":310,"abstract":311,"tags":314},[],[312,313,301],"灌溉","水资源",[296,297],{"code":32,"score":20,"supported":45,"title":316,"abstract":317,"tags":319},[],[48,318,50],"气候适应",[],{"code":53,"score":54,"supported":45,"title":321,"abstract":322,"tags":323},[],[57,58],[26],{"code":325,"score":19,"supported":45,"title":326,"abstract":327,"tags":330},"H2",[],[328,329],"土壤","soil",[],{"code":141,"score":21,"supported":14,"title":332,"abstract":333,"tags":334},[],[],[295],[336,337],"乌兹别克斯坦 灌溉水效率","滴灌 农场生产力","乌兹别克斯坦灌溉水效率-4516","10.5281\u002Fzenodo.23204413",{"doi":339,"openalex_id":341,"authors":342,"venue":286,"cited_by_count":78,"oa_url":283,"card":345,"direction":86,"ingested_from":87},"W7220939870",[343],{"name":344,"orcid":9},"Yusupov Yusufbek",{"tldr":346,"method":347,"finding":348,"direction":349,"opportunity":350},"综述乌兹别克斯坦农业水资源可持续管理与农场生产力的关系及经济制约。","系统叙述性文献综述，分析灌溉效率、数字技术等国际机构资料。","滴灌、遥感等可提效，但受高投资、资金、技术和制度协调不足制约。","农业绿色发展与碳","可实证评估数字灌溉系统在中亚干旱区的小农采纳障碍与政策激励效果。","2026-10-09T23:30:28.853699Z",{"id":353,"title":354,"url":355,"summary":356,"summary_zh":357,"content":9,"source_name":358,"source_url":355,"published_at":359,"category":12,"cover_url":9,"hotness":13,"is_selected":45,"score":360,"score_detail":361,"sources":364,"tags":366,"primary_topic":371,"secondary_topics":372,"classification":373,"search_phrases":398,"slug":401,"view_count":78,"doi":402,"paper":403,"created_at":415},4080,"Genomic repetition in climate adaptation across different crop species","https:\u002F\u002Fdoi.org\u002F10.32942\u002Fx2wq32","Commercial crop varieties (cultivars) have a narrow genetic diversity that makes them vulnerable to climate change. Yet most crops have related semi-domesticated varieties (landraces) and wild relatives that thrive under climates that would be considered extreme for cultivars. The genomes of such varieties are reservoirs of unknown adaptive traits, some of which could be used to extend the climatic tolerance of cultivars. To shed light on these traits, we built a genomic database of fourteen crop types, including landraces and wild relatives of staple crops. This database included individual-level genomic data for plants from over 3,000 locations worldwide. Leveraging remote sensing and climatic models, we reconstructed bioclimatic conditions, soil types, and human disturbance for each of these locations. Genes whose geographic variation correlates with an environmental gradient are potentially implicated in local adaptation; if the same gene repeatedly shows this association in different crops, its adaptive role is more likely. We found 16 groups of genes showing such repeated environmental associations, mainly linked to water availability and cold-season temperature. For some of these genes, the same climate association was observed in 6, 7, or even up to 13 crop types. Using A. thaliana as a reference, we found that many of these genes likely encode proteins already well known to regulate cellular responses to drought and cold stress. Our findings suggest that natural variation in these genes can enhance such responses, and that such variation exists in landraces and wild relatives of different crops. If validated, this finding could open new avenues to make cultivars more climate-tolerant via genomic-guided breeding.","商业作物品种（栽培品种）的遗传多样性狭窄，使其易受气候变化影响。然而，大多数作物都有相关的半驯化品种（地方品种）和野生近缘种，它们在对栽培品种而言属于极端的气候条件下仍能茁壮生长。这些品种的基因组是未知适应性性状的储库，其中一些性状可用于拓展栽培品种的气候耐受性。为揭示这些性状，我们构建了一个涵盖14种作物类型的基因组数据库，包括主粮作物的地方品种和野生近缘种。该数据库包含来自全球3000多个地点的植物个体水平基因组数据。借助遥感与气候模型，我们重建了每个地点的生物气候条件、土壤类型和人类干扰情况。地理变异与某一环境梯度相关的基因可能参与局部适应；若同一基因在不同作物中反复表现出这种关联，则其适应性作用更有可能成立。我们发现了16组表现出此类重复环境关联的基因，主要与水分可利用性和冷季温度有关。其中一些基因在6种、7种甚至多达13种作物类型中观察到相同的气候关联。以拟南芥（A. thaliana）为参照，我们发现许多此类基因可能编码已知调控细胞对干旱和冷胁迫响应的蛋白质。我们的研究结果表明，这些基因的自然变异可以增强此类响应，且这种变异存在于不同作物的地方品种和野生近缘种中。若得到验证，这一发现可能为通过基因组引导育种使栽培品种更具气候耐受性开辟新途径。","OpenAlex","2026-09-30T00:00:00Z",84,{"impact":18,"substance":362,"depth":17,"authority":237,"freshness":135,"relevant":21,"comment":363},23,"构建14类作物、3000余个地点基因组数据库，发现16组跨作物重复环境适应基因，为气候耐受育种提供新靶点，数据规模与方法均有实质增量。",[365],{"name":358,"url":355},[26,367,368,369,370],"种业振兴","基因组育种","气候适应性","作物野生近缘种",{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},[],{"status":39,"locked":14,"version":40,"method":41,"evidence":374},{"candidates":375,"agricultural_evidence":45},[376,380,384,388,393],{"code":32,"score":20,"supported":45,"title":377,"abstract":378,"tags":379},[],[48,49,50,239],[],{"code":53,"score":54,"supported":45,"title":381,"abstract":382,"tags":383},[],[57,58],[26],{"code":325,"score":19,"supported":45,"title":385,"abstract":386,"tags":387},[],[328,329],[],{"code":389,"score":21,"supported":14,"title":390,"abstract":391,"tags":392},"F1",[],[],[367],{"code":394,"score":21,"supported":14,"title":395,"abstract":396,"tags":397},"F2",[],[],[368],[399,400],"作物 野生近缘种 基因组 气候适应","地方品种 抗旱 抗寒 基因","作物野生近缘种基因组气候适应-4080","10.32942\u002Fx2wq32",{"doi":402,"openalex_id":404,"authors":405,"venue":9,"cited_by_count":78,"oa_url":409,"card":410,"direction":86,"ingested_from":87},"W7214896481",[406],{"name":407,"orcid":408},"Oliver M.

This study aimed to map and improve spatial estimation of SOC stocks in Sudan’s Blue Nile clay soils using regression kriging (RK). The model integrated 554 spatially unique soil profiles with nine environmental covariates: precipitation, temperature, relative humidity, normalized difference vegetation index (NDVI), land use\u002Fcover, bare soil index (BSI), digital elevation model (DEM), LS-factor, and aspect. Spectral indices were derived from Landsat 9 imagery (April 2024), while climate and terrain data were obtained from CHIRPS\u002FWorldClim and SRTM (30 m). RK performance was robust, with spatial cross-validation R 2 = 0.72, RMSE = 8.4 Mg C ha −1 (29% of mean observed stock), and mean bias = −0.8 Mg C ha −1 . Predicted SOC stocks (0–30 cm) ranged from 12.4 to 51.2 Mg C ha −1 (mean 28.6 Mg C ha −1 ). NDVI, clay content, and topographic wetness index were the most influential predictors. Agricultural lands exhibited the highest stocks (51.2 Mg C ha −1 ), while bare lands had the lowest (14.2 Mg C ha −1 ). This study (1) applies spatially explicit validation for SOC mapping in Sudan’s Blue Nile region, (2) harmonizes legacy and contemporary soil data using equivalent soil mass correction, and (3) provides high-resolution SOC maps for climate-resilient agricultural planning. Findings support soil carbon management and climate mitigation in semi-arid regions.","土壤有机碳（SOC）储量是陆地碳库的重要组成部分，影响土壤质量、农业生产力及气候变化减缓。本研究旨在利用回归克里金（RK）方法对苏丹青尼罗河黏土区SOC储量进行制图并改进其空间估算。该模型整合了554个空间独立土壤剖面与9个环境协变量：降水、温度、相对湿度、归一化植被指数（NDVI）、土地利用\u002F覆盖、裸土指数（BSI）、数字高程模型（DEM）、LS因子和坡向。光谱指数源自Landsat 9影像（2024年4月），气候与地形数据分别来自CHIRPS\u002FWorldClim和SRTM（30 m）。RK表现稳健，空间交叉验证R²=0.72，RMSE=8.4 Mg C ha⁻¹（为实测储量均值的29%），平均偏差=−0.8 Mg C ha⁻¹。预测SOC储量（0–30 cm）范围为12.4–51.2 Mg C ha⁻¹（均值28.6 Mg C ha⁻¹）。NDVI、黏粒含量和地形湿度指数是最具影响力的预测因子。农地储量最高（51.2 Mg C ha⁻¹），裸地最低（14.2 Mg C ha⁻¹）。本研究（1）对苏丹青尼罗河地区SOC制图采用空间显式验证，（2）利用等效土壤质量校正协调历史与当代土壤数据，（3）为气候韧性农业规划提供高分辨率SOC图。研究结果支持半干旱地区的土壤碳管理与气候减缓。","Spanish Journal of Soil Science",68,{"impact":135,"substance":168,"depth":169,"authority":237,"freshness":20,"relevant":21,"comment":425},"基于554个土壤剖面与多源遥感协变量的回归克里金制图研究，方法规范、验证充分，对半干旱区土壤碳管理与气候适应型农业规划有参考价值，但属区域性学术成果，公共影响有限。",[427],{"name":422,"url":419},[26,48,57,429,430],"土壤碳汇","数字土壤制图",{"code":325,"slug":329,"name":432,"path":433,"parent_code":36},"土壤健康与改良","\u002Ftopic\u002Fenvironment\u002Fsoil",[435],{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},{"status":39,"locked":14,"version":40,"method":41,"evidence":437},{"candidates":438,"agricultural_evidence":45},[439,443,447,453,457],{"code":325,"score":100,"supported":45,"title":440,"abstract":441,"tags":442},[329],[328,329],[],{"code":32,"score":13,"supported":45,"title":444,"abstract":445,"tags":446},[],[48,49,50],[48],{"code":448,"score":71,"supported":45,"title":449,"abstract":450,"tags":452},"J1",[],[451],"农业规划",[],{"code":53,"score":259,"supported":14,"title":454,"abstract":455,"tags":456},[],[],[26,57],{"code":458,"score":21,"supported":14,"title":459,"abstract":460,"tags":461},"H4",[],[],[429],[463,464],"苏丹青尼罗河 土壤有机碳 回归克里金","Landsat 9 土壤有机碳 空间预测","苏丹青尼罗河土壤有机碳回归克里金-3191",5,"10.3389\u002Fsjss.2026.16733",{"doi":467,"openalex_id":469,"authors":470,"venue":422,"cited_by_count":78,"oa_url":419,"card":479,"direction":84,"ingested_from":87},"W7213971196",[471,473,475,477],{"name":472,"orcid":9},"Faroug A.H.
