Understanding how climate change will affect water quality and therefore, health, is critical for building resilient services in low- middle-income countries (LMICs) where the effect of be felt most acutely. Evidence variables such as temperate rainfall on can generate insights into likely impact future change. While seasonal effects are known, there strong qualitative evidence that quality, no reviews synthesise quantitative from LMICs links between quality. We mapped available a range exposures outcomes identified 98 peer-reviewed studies. This included observational studies temperature events (which may cause short-term changes contaminant concentrations), modelling long-term impacts sea level rise. antecedent microbiological contamination supplies relatively evenly distributed geographically, but largely focused faecal indicator bacteria untreated shallow groundwater sources drinking water. The literature geogenic contaminants was sparse. There substantial research cyanobacteria blooms surface waters, although were two did not examine potential treatment. Similarly, rise salinity, mostly south-Asia Middle East, discuss challenges supplies. key priorities based this review. These include: more specific pathogens (including opportunistic pathogens) their relationships with variables; assess treatment processes; contaminants, including risks heavy metals released glacier retreat; and, wildfires given current dearth recognised importance.

Bibliometric network analysis of scientific research on early warning signals for cyanobacterial blooms in lakes and rivers

Ecological Informatics, Journal Year: 2024, Volume and Issue: 80, P. 102503 - 102503

Published: Jan. 28, 2024

Harmful cyanobacterial blooms (HCBs) present a major risk to inland waters; therefore, various monitoring and management frameworks have been implemented protect water quality, aquatic organisms, humans from their negative impacts. Enabling proactive rather than reactive management, early warning systems within the lead time of HCBs at timescales ranging hours days is necessary provide managers with timely, evidence-based information for decision-making. To state-of-the-art system HCBs, this study systematically reviewed scientific publications indexed in Web Science through bibliometric approaches, investigating current trends developments. By focusing on literature addressing period preceding quantitative network analysis identified key indicators, state variables, forecast horizons. Consequently, 116 documents related eutrophic lakes reservoirs temperate, Mediterranean, subtropical climates were analyzed. The frequently used HCB predictors these studies chlorophyll-a (chla) concentration temperature, while commonly targeted outputs chla cell density. Co-occurrence keywords addressed six clusters as main research fields: molecular monitoring, remote sensing, situ resilience indicator utility, inferential deterministic modeling. similarly by selected publications; however, specific terms associated identification, taste, odor compounds not observed. results suggest that considerable progress requires enhancing interdisciplinary integrate most relevant technologies, environmental ecological knowledge about HCBs.

Climate Change Impacts on Water Temperatures in Urban Lakes: Implications for the Growth of Blue Green Algae in Fairy Lake

Water, Journal Year: 2024, Volume and Issue: 16(4), P. 587 - 587

Cyanobacteria, also known as blue-green algae, are photosynthetic bacteria that play a crucial role in aquatic ecosystems and susceptible to changes temperature. Hence, global temperatures rise due climate change, some Cyanobacterial species will thrive warmer temperatures, which result increased blooms during the growing season. The MIKE-3 model is calibrated existing (2022) conditions used assess impact of RCP 4.5 scenario for year 2050 Fairy Lake (a shallow urban lake Ontario). simulations projected indicate 2050, central parts Lake’s basin, water be above 20 °C 2281 h compared 2060 2022.
