Abstract Background Climate change is increasingly affecting the supply of resources such as water and food. From 2015 to 2018, Cape Town endured its most severe drought on record. Yet, resource management often occurs in isolation, which contrasts with holistic perspective provided by nexus concept that recognizes interdependence sectors. This study employs system dynamics modelling, examine City Town’s (CoCT) water-food trade-offs interactions using qualitative quantitative approaches. It assesses various policies proposed CoCT, improve resilience boost future supplies, examining their efficacy potential drawbacks. These are tested against scenarios including population growth climate predictions different severities. Results The simulation results show an increase food demand, mainly linked a significant decrease availability. Without interventions, CoCT expected experience serious shortages within 40-year period. Conclusions findings indicate CoCT’s strategies will effectively secure adequate for expanding population. However, major concern was found be intensification aquifer exploitation. model predicts approach could lead over-abstraction some aquifers, compromising sustainability.

Despite Nigeria's immense wealth in water resources, the country faces a significant crisis that is exceptionally difficult to resolve, particularly considering associated public health and security challenges. This review aims expound on complex determinants outcomes of shortage Nigeria focusing more its effects general livelihood stability Nigerians. Using systematic approach, this paper reviews scarcity, causes pollution– including urban activities, agrochemical run-offs, mismanagement – their negative impacts environment Nigeria. A total 305 studies relating pollution were examined study. One point evaluation outlines existing barriers preventing all-inclusive availability clean water, for example, lack appropriate infrastructure inefficient resource management. The emphasizes improving treatment facilities, advancing management strategies are sustainable, tightening certain laws.

Droughts can affect a multitude of public and private sectors, with impacts developing slowly over time. While droughts are traditionally quantified in relation to the hydrological components water cycle that they affect, this manuscript demonstrates novel approach assess future drought conditions through lens water-energy-food-ecosystem (WEFE) nexus concept.

Abstract The water-energy-food-ecosystems (WEFE) Nexus has gained recognition as an innovative approach for analysing the interconnectedness of global resource systems and achieving sustainability goals. In Mediterranean, where water scarcity, climate change, ecosystem degradation pose significant challenges, implementing integrated WEFE is crucial. We conducted a comprehensive review scientific literature through lenses ‘ideas’, ‘relationship’ ‘practices’. A total 142 research articles were selected characterized in terms interlinkages being investigated, explored topics, methods scales analysis, contexts operationalization. found that water-energy interdependences dominate driven by large presence energy-intensive abstraction distribution to meet drinking irrigation demands. At same time, expansion additional components only partial, mostly focusing on assessing impacts physical environment climate, without capturing feedback dynamics. Geographically, Mediterranean primarily isolated case studies, with few scale assessments developed at entire scale, some countries not yet represented, particular Western Balkans. Although recognizing importance transdisciplinarity moving beyond biophysical encompass societal governance dynamics, further needed understanding economic implications interactions. To advance implementation region, sustainable technology, natural resources management, which are key fields operationalization, would benefit from harmonization their design objectives. This enable more coherent towards water, food, energy security while preserving region.

The Jordan Valley (JV) is a critical region where the interplay of water, energy, food, and ecosystem (WEFE) dynamics presents both challenges opportunities for sustainable development climate change mitigation adaptation. In such transboundary river basin with acute nexus problems long history conflicts, it essential that conscious efforts are made to pluralize debate actively encourage stakeholders' empowerment, participation fair collaboration in strategic planning. An integrated framework participatory planning WEFE proposed, which has been developed context JV case study. approach emphasizes decentralized, but coordinated decision making as source solutions, based on clear understanding faced. engagement process consisted living lab sessions Causal Loop diagrams facilitated discussions stakeholders by visualizing complexity interdependence sectors prioritizing Community capacity assessment appraised capacities each community, identifying barriers addressing their priorities. Finally, gap analysis bridged baseline actionable targets. results not only highlight pressing challenges, priorities, leverage points territory also outline pathways fostering resilience adaptation region's intertwined crises. priorities across three territories reveal significant disparities, reflecting diverse socio-political, environmental, economic contexts region. methodologies overall may be replicated other regions similar around world.
