Abstract
A larger population will not only use more water but will discharge more wastewater. Water quality programs are not fully developed even in the industrialized countries and are nonexistent in most developing countries, where they are most needed. Furthermore, the costs for managing water supplies are increasing, as are the demands on limited financial resources. Wetlands are productive zones that form life support systems for aquatic organisms and provide resources for human beings. The wetlands both the water body and the transitional zone between land and water are often subjected to stress by various factors, the common incidences are drought and flood. This is partly due to the natural variability of climate and partly to inappropriate land and water use. To sum up, we may now have to consider the effects on water of not only the natural variability of climate and more population pressure but also what appears to be a change in climate that is brought about by human activity. This review paper examines the scientific and institutional linkages between climate changes and the conservation and wise use of wetlands. Following the introduction, this paper reviews the state of knowledge concerning the impact of climate change on wetlands including freshwater resources, coral reefs, and other coastal, fresh water and marine wetlands. These impacts include sea-level rise, coral bleaching, changes in water temperature, and alterations in water availability and quality.
