ABSTRACT
Environmental concerns associated with nutrient-oriented eutrophication
phenomenon have become a serious
issue and a major cause of water quality deficiency nowadays. This necessitated eutrophication to
occupy a front seat in research accompanied with climate change. Climate change
has revealed to be a key player and a main contributor in the occurrence of
such phenomenon. This paper discusses the ever-growing concern about
eutrophication as a cause of climate change. Climate change affects storms intensity,
changing the precipitation regime and increasing temperature. These effects
increase the nutrient loading diffusion and cause excessive nutrients
accompanied with storm water runoff,
domestic wastewaters, and agricultural discharges to pour into water bodies.
Eutrophication conversely contributes in the global warming by releasing
greenhouse gases from deoxygenated waters and sediments. Some control and
mitigation measures are needed to fight climate
change and achieve desired water quality goals. These measures include mitigation of climate change causes, enhancement of
natural ecohydrological processes, application of
proper integrated water resource management and participation of communities
and governments.
