The volume of freshwater resources is around 35 million km3, or about 2.5% of the total volume.
The total freshwater supply available for ecosystems and humans is less than 1% of all freshwater resources.
This final Plan will be the foundation for Federal agency efforts to manage freshwater resources as the climate changes.
The work represents the most comprehensive assessment of global freshwater resources to date.
Climate change is expected to modify the hydrological cycle and affect freshwater resources.
This flagship Report is a comprehensive review that gives an overall picture of the state of the world's freshwater resources.
Of these freshwater resources, about 24 million km3 or 70% is in the form of ice and permanent snow cover in mountainous regions, the Antarctic and Arctic regions.
On June 2, 2011, the Council on Environmental Quality (CEQ) released a draft "National Action Plan: Priorities for Managing Freshwater Resources in a Changing Climate, " for public review and comment.
International World Water Day is held annually on 22 March as a means of focusing attention on the importance of freshwater and advocating for the sustainable management of freshwater resources.
Large areas of Africa receive little rainfall for much of the year, so even though Africa covers 20% of the world's land area, it only has 9% of global freshwater resources.
Climate change is already adversely affecting many areas, including biodiversity and ecosystems, freshwater resources, human health, human settlements and migration patterns, the conservation of natural and cultural world heritage properties, and peace and prosperity.
The problem arises when actions in other domains ignore or misunderstand that water underpins the entire green economy, and that without planning for good management of freshwater resources the entire movement is put at risk.
The overarching target of the World Water Assessment Programme (WWAP) is to inform the decision making mechanism by providing comprehensive information on the state, use and management of freshwater resources, highlighting the trends and pointing out to consequences and possible futures.
Moving towards an increasingly integrated approach to sustainable development in small islands, CSI focused on local community perceptions and knowledge relating to the conservation and wise use of freshwater and coastal resources.
They are areas set up to serve as places to test different approaches to integrated management of terrestrial, freshwater, coastal and marine resources and biodiversity.
Biosphere Reserves are areas designated under UNESCO's Man and the Biosphere (MAB) Programme to serve as places to test different approaches to integrated management of terrestrial, freshwater, coastal and marine resources and biodiversity.
These include increasing social disparities and inequity, population growth, climate change, the deterioration and pollution of the environment, the unsustainable use of freshwater and depletion of ocean resources, as well as increasing cases of natural and human-made disasters.
This report, produced by the Interagency Climate Change Adaptation Task Force, provides an update on actions in key areas of Federal adaptation, including: building resilience in local communities, safeguarding critical natural resources such as freshwater, and providing accessible climate information and tools to help decision-makers manage climate risks.
