Introduction. The southern regions of Russia need to adapt higher peak river flows and flash floods. Since 1960, the number recorded flood events has increased. intensity severity tend decrease, but their annual frequency is increasing. This illustrates social component flooding. Trends in are closely related increasing population valleys. “Integrated management” construction sites basins based on three elements: monitoring, forecasting early warning, vulnerability assessment, mitigation response. purpose this study establish means prediction, risk assessment operational projects taking into account current natural climatic factors.

The water allocation problem is complex and requires a combination of regulations, policies, mechanisms to support management minimize the risk shortage among competing users. This paper compiles application multi-criteria decision-making (MCDM) related allocation. In this regard, aims identify discern pattern, distribution study regions, classifications, decision techniques for specific problem. We applied systematic literature review from 2000 2019 by using four databases (Web Science, Scopus, Science Direct, Google Scholar). From 109 papers, 49 publications have been identified information extracted. reveals that in past two decades MCDM area has increased particularly after 2014. Around 65% 12% papers were conducted Asia Europe, respectively. Water shortage, use management, quality consecutively most top-ranked discussed problems. NSGA II (non-dominated sorting genetic algorithm), GA (genetic LP (linear programming) are more often methods solve key findings provide guidelines future research studies.

Abstract The world is nearing the 2030 target‐year by which sustainable development goals (SDGs) should be achieved. While other developing regions seem to making progress toward achieving SDG6, sub‐Saharan Africa (SSA) lagging behind significantly, particularly with regard access water supply and sanitation (WSS). As a result, most studies evaluating achievement of security SDGs in SSA have focused on WSS while rest SDG6 targets received scant attention, often using fragmented or incomplete evidence. Here, we fill this knowledge gap conducting comprehensive assessment status all 48 countries SSA. We provide review made, challenges affecting each target examine different political, socioeconomic, environmental factors potential undermine region. Our clearly demonstrates that it likely may not achieve 2030. complex nature impeding outlined here suggests holistic intervention involving local, national, international stakeholders research community urgently needed address if date met.

The Pra River Basin in Ghana is a major source of ecological, cultural, and economic benefits. However, it has been experiencing degradation, logistical constraints have limited the implementation Integrated Water Resources Management. This study presents GIS-based ecohydrological risk model that identifies units with highest degradation risk. First, PRB was divided into 25 eco-hydrological units. Second, seven drivers were identified mapped. reclassified five categories scores 1–5, 5 indicating higher scores. variables ranked using Analytical Hierarchy Process, calculated weighted sum method, multi-criteria decision tool used to identify Of delineated, Buama, Lower Offin, Ayensu, Oda found be at due high artisanal small-scale gold mining, population density, low forest/vegetation cover, encroachment waterways. results can as guide prioritize management intervention, starting areas classified moving down those moderate

High urbanization in Sub-Saharan Africa (SSA) has resulted increased peri-urban groundwater contamination by on-site sanitation. The World Health Organization introduced Water Safety Plans (WSP) towards the elimination of risks to water supply systems; however, their application sources been limited. Focusing on Uganda, Ghana, and Tanzania, this paper reviews limitations existing regime addressing through WSPs normative attributes Transition Management (TM) a sustainable solution. Microbial nutrient remain prevalent hazards SSA, arising from sanitation within following Integrated Resources (IWRM) principles. Limitations implementation for protection include policy diversity, with low focus groundwater; institutional incoherence; highly techno-centric management tools; limited regard socio-cultural urban-poor aspects. In contrast, TM postulates prescriptive approach promoted community-led frontrunners, flexible multi-domain actors, experimenting socio-technical tools shared vision. Thus, unified risk-based framework, harnessing IWRM, is proposed improved WSP implementation. framework could assist communities policymakers formulating strategies reduce contamination, thereby contributing access safe water.
