The Amazon, the Congo, and the Irrawaddy are just a few of the rivers at risk of losing their free-flowing status if the proposed construction of new hydropower dams takes place.</p> Thu, 12 Aug 2021 14:00:28 +0000 webfull 172198 at /channels /channels/channels/news/most-rivers-run-dry-now-and-then-331517 <p>A new study led by researchers from <a href="//www.mcgill.ca/newsroom/">Æ»¹ûÒùÔº</a> and <a href="https://www.inrae.fr/en">INRAE</a> found that between 51-60% of the 64 million kilometres of rivers and streams on Earth that they investigated stop flowing periodically, or run dry for part of the year. It is the first-ever empirically grounded effort to quantify the global distribution of non-perennial rivers and streams.</p> Wed, 16 Jun 2021 17:21:05 +0000 webfull 171179 at /channels /channels/channels/news/worlds-most-detailed-database-maps-characteristics-earths-rivers-and-catchments-303255 <p>Two researchers and friends from opposite ends of the Earth have created a world-first high spatial resolution atlas that maps the environmental characteristics of all the globe's rivers and catchments.</p> <p>HydroATLAS was co-developed by Bernhard Lehner and his team from Æ»¹ûÒùԺ’s Department of Geography and Simon Linke from Griffith University’s Australian Rivers Institute.</p> Mon, 09 Dec 2019 16:12:18 +0000 webfull 156233 at /channels /channels/news/new-global-wetlands-map-241106 Thu, 15 Jan 2015 14:59:05 +0000 webfull 107537 at /channels /channels/news/measuring-protection-world%E2%80%99s-rivers-263979 <p>To  what extent are the world’s rivers protected?  </p> <p><span>In 2010, the Convention on Biological Diversity (CBD), an international treaty for the conservation of biodiversity, </span><a href="https://www.cbd.int/sp/targets/">set a 17% target</a><span> for the protection of ‘inland waters,’ including rivers. But there was a problem: there was no good way to measure progress toward that target.  </span></p> Thu, 10 Nov 2016 18:42:29 +0000 webfull 122928 at /channels /channels/news/better-dam-planning-strategies-240951 <p>When dams are built they have an impact not only on the flow of water in the river, but also on the people who live downstream and on the surrounding ecosystems. By placing data from close to 6,500 existing large dams on a highly precise map of the world’s rivers, an international team led by Æ»¹ûÒùÔº researchers has created a new method to estimate the global impacts of dams on river flow and fragmentation.
