Topic: Coastal water


  
  Water ecology FAQ
Coastal wetlands are particularly important because they protect coastal land from flooding and from damage and erosion caused by storms.
Most water bodies are now severely polluted, because we have been discharging wastewater in it for a very long time, before we realised this was very bad for the water quality.
Coastal life zones are particularly sensitive to toxic contamination, because they are a dump for pesticides, heavy metals and other pollutants, which will soon accumulate to high levels.

 USAID Environment: Water
Water shortages and poor water management can lead to loss of biodiversity and agricultural production, increase in malnutrition and disease, reduced economic growth, social instability, and conflict.
Water resources are not distributed uniformly across the globe — nor are they necessarily located where the largest concentrations of people reside.
Coastal systems are particularly vulnerable to degradation from land-based activities, climate change, over-fishing, and damage to coral reefs, and they require active intervention to ensure their continued survival.

 COASTAL WATER QUALITY MONITORING
Coastal monitoring is important to the success of regulatory programs and informs decision-makers and the public about the health of the marine environment.
Periodic monitoring of coastal water quality conditions provides water quality program managers with the feedback needed to evaluate whether coastal water quality and marine resources are being protected, and whether clean water programs are working as originally designed.
Because the marine resources, water quality issues, and monitoring programs are unique to each bioregion, stakeholders within that region are best suited to design and conduct monitoring studies in their bioregions in regard to such factors as choice of the appropriate indicator species and identification of reference sites.

 NOAA Office of Ocean and Coastal Resource Management : Nonpoint Pollution
The Coastal Nonpoint Pollution Control Program was established by Congress in 1990 to encourage better coordination between state coastal zone managers and water quality experts to reduce polluted runoff in the coastal zone.
Poor water quality is not just a result of what we do to the water but what we do on the land as well.
Therefore, establishing shared responsibilities for managing coastal water quality between state coastal zone management agencies, who make land use decisions, and water quality agencies, who deal directly with the quality of our coastal waters, is needed.
