Climate Change Impacts on Water Quality of Water Bodies-A Review

Abstract

The impacts of climate change on water quality of water bodies are associated with the climatic extreme events (heavy rainfall and flood, heat, drought, wildfires, cyclones, hurricane, super storms) as the major drivers that require knowledge of understanding. Most research studies present the role of climate change in threatening water quality, risks on drinking water and contributions of catchment in water pollution, but less attention has directed to specific sensitive water quality parameters, appropriate methodologies, risks on ecosystem and managerial practice to reduce the impacts. This review highlight the of effect climate change on surface water bodies based on recent literatures on the impacts of climate change on water quality and promote practical opportunity for better management of these impacts. We conclude that consideration of climate change preparedness plan in catchments is the best option to adopt for minimization of climate change impacts on water quality of water bodies.

Network-Based Topological Exploration of the Impact of Pollution Sources on Surface Water Bodies

“…Potential impacts of climate change on surface water quality and water bodies have been studied considering the average increase in global temperature, extreme events, heavy rainfall and floods, sea-level rise, droughts, etc. Changes in water quality parameters can reflect the effects of climate change on chemistry and water ecology (Salila et al, 2020). Extreme heat and increased global temperatures will likely cause an increase in the water temperature and biochemical reactions in streams (Yang et al, 2019), (Nguyen et al, 2017) as well as a reduction in Dissolved oxygen leading to the disappearance of some microspecies (Du et al, 2019), (Mehdi et al, 2018).…”

Variabilidade climática e qualidade da água em três lagoas da Bacia Hidrográfica do Rio Tramandaí, RS, Brasil

“…A temperatura da água é uma variável de grande importância, pois ela influencia o metabolismo das comunidades, com impacto na produtividade primária e na decomposição da matéria orgânica (Santos et al, 2002). Quando relacionando com possíveis efeitos das mudanças climáticas, a temperatura é um principal efeito, que impacta os parâmetros de qualidade de água (Salila et al, 2020). Entende-se que uma lâmina de água menor (mais rasa) oportuniza a alteração mais rápida da temperatura da água em função da mudança na temperatura do ar, gerando mais aquecimento das águas ou resfriamento, principalmente em função da intensidade dos ventos, que favorece na homogeneização os corpos hídricos.…”

Adaptation strategies for climate change impacts on water quality: a systematic review of the literature

“…Shannon et al (2019) propose avoidance or reduction in the use of organic supplements, nutrients, and chemical delivery to areas near waterbodies. Many others (Whitehead et al 2006;Chiang et al 2012;Ha & Wu 2017;Salila et al 2020) support crop nutrient management to reduce pollutant loading in the waterways.…”

“…and Salila et al (2020) propose improved crop choices, whileWhitehead et al (2009aWhitehead et al ( , 2009b recommend crops that are better suited to the climatic conditions.Cherkauer et al (2021),Wardropper & Rissman (2019),Whitehead et al (2006), andHa &Wu (2017) recommend the use of cover crops which can reduce soil erosion and absorb the nutrients remaining in the soil.…”
