This Worldview of the UN Atlas of the Oceans presents material by geographic areas.
The interactive world map allows a geographic search of all topics and knowledge objects in the UN Atlas. Geographic areas have been developed using the AGROVOC Thesaurus, published by the Food and Agriculture Organization of the United Nations (FAO), as a global standard.
Boundaries and names shown and the designations used on the map do not imply official endorsement or acceptance by the United Nations.
Maps, Statistics and Databases offers an entry point to all maps currently available from the UN Atlas. Following the links below, the user can directly access maps on particular topics and external collections of maps related to the oceans.
Rivers are dynamic systems, with their courses and flows constantly changing due to natural and human responses. The world's main channel river length amounts to about 269 000 km, with the highest density of rivers located in South America. Major river and floodplain systems are very important to Asian countries. Rivers play a substantial role for capture fisheries -- their contribution to food security is often underestimated as statistics do not include the component consumed by fishers.
