“…According to the data on water withdrawal, groundwater resources provide roughly 63% of Florida's overall water supply and 85% of its public water [47]. Even with a mean annual rainfall of 137 cm across Florida [48], fresh groundwater withdrawal is currently close to the limits of sustainability in much of the state due to environmental issues and demands for natural-resource constraints [24,38,49].…”

“…The district's resiliency efforts focus on assessing how sea level rise and extreme events occur under current and future climate conditions and their impact on water resources management, infrastructure adaptation, and restoration of ecosystems [49,110]. The district is also working to remove and reduce excess nutrient pollution from entering natural systems [118].…”

Emerging changes in water availability in the U.S. state of Florida have been recognized as a combined result of human perturbations, natural variability, and climate change. Florida is particularly susceptible to the impacts of the sea level rise due to its extensive coastline, low elevation, and lack of topographic relief to promote drainage. Owing to the porous nature of the state’s aquifer systems, saltwater intrusion into coastal areas is an evolving threat. Additionally, anthropogenic intervention has increased the contribution of nutrients and sediments to many lakes, reservoirs, and rivers, subsequently causing eutrophication and sedimentation problems. The state is facing the challenges of ocean acidification head-on since, in many regions, groundwater aquifers are connected to coastal waters, where water circulates from land to sea through the underlying porous limestone. Additionally, as Earth’s atmosphere warms up, extreme weather events are expected to change the environmental fate of contaminants in the aquatic environment, and this, in turn, may impact the type and distribution of contaminants in source waters. This review paper highlights five major emerging themes that are of significance for sustainable long-term management of Florida’s water resources: (i) influences of changing climate on groundwater aquifers; (ii) implications of climate change on eutrophication; (iii) impacts of changing climate on the Everglades; (iv) climate-change influence on runoff and sediment loads; and (v) influence of ocean acidification on coastal water. The findings of this review indicate that, in the future, the changing global climate will likely alter numerous environmental conditions in Florida, and the resulting changes may impact the natural properties of the state’s fresh and coastal waters. The findings are expected to mobilize knowledge in support of the changing climate to assist Floridians to adapt to its effects.

“…The South Global is generally more vulnerable to climate impacts [1]. Climate Change impacts erosive vulnerability leading to land degradation [2], considering how changing temperatures and precipitation patterns affect water resources and watershed ecosystem [3], causing flood, river banks erosion, widening of river channels, increasing pollutant loads, decreasing aquatic life [4], increasing sea level [5], rising problem with regional and global water scarcity [6], broad impact on food security [7].…”

Water is useful for supplying household, industrial, and agricultural needs. The availability of water supports food security and decent life. The process of sustaining water resources requires conservation, which is in line with sustainable development goals. The Keyang sub watershed is one of the catchment areas of the Upstream Madiun River, located in East Java. The development of agriculture land in Keyang sub watershed increases the number of disasters. The Central Statistics Office of Ponorogo Regency recorded 24 floods, 11 drought disasters, and 42 landslides in Keyang sub watershed during 2020. Floods and drought disasters in the same location show strong fluctuations in water resources, so Keyang sub watershed requires water conservation actions. The aim of this study is to analyze priority locations for water conservation. Indicateurs de Ruissellement Intense Pluvial (IRIP) is a method for determining water conservation priority locations. IRIP divides surface runoff vulnerability area into three types: generation area, transfer area, and accumulation area. Each area requires different adaptations to conservation techniques. The result shows that Keyang sub watershed has 4.96% strong potential surface runoff generation area. This priority area is suitable for wetland development, agroforestry, and sustainable agriculture. Then, Keyang sub watershed has 0.03% strong potential area of surface runoff transfer, this area is compatible with prevention of erosion and landslides. Keyang sub watershed has 0.63% very strong potential and 18.42% strong potential for surface runoff accumulation area. Accumulation area appropriate for developing flood mitigation strategies.

The Cantareira Water Production System (CWPS), which supplies water to the most populous region in Brazil, is facing significant challenges due to hydroclimate change, thus threatening its water security. This research integrates data from climate models and field observations with hydrological modeling, aimed at quantifying trends in key variables of the hydrological cycle. The GFDL-CM4 climate model, the most suitable for the study area, was employed to generate runoff data under both current conditions and future scenarios (SSP2-4.5 and SSP5-8.5). Our analysis reveals an increasing trend in the frequency of dry hydrological years. The Standard Precipitation Index (SPI) and Drought Magnitude (DM) confirm an increase in both the occurrence and duration of droughts in future scenarios. The runoff in all basins was reduced, causing a substantial decrease in minimum flows of 16.9%, medium flows of 11.8%, and high flows of 9.2% for the SSP5-8.5 scenario. This research introduces an approach to hydroclimate impact assessment, combining rigorous data analysis with advanced modeling techniques. Our findings not only provide a comprehensive understanding of the challenges faced by the CWPS, but also offer critical quantitative insights essential for developing effective public policies and adaptive strategies for sustainable water resource management.
