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.
