CORVALLIS, Oregon, USA. – New research shows that recent climate change is having profound effects on wetlands across the American West – affecting birds that use these wetlands for breeding, migration and wintering. Read More...
According to a study published today in the journal Scientific Reports, long-term trends towards higher temperatures and less precipitation have altered environmental water quality and reduced waterbird habitat, creating clear winners and losers in bird species and potentially threatening the integrity of the Pacific migratory flyway for many species. The study, which began in the mid-1990s, is the result of a research collaboration between scientists at Oregon State University, U.S. Geological Survey, University of California, Merced; and the Alliance for Global Water Adaptation.
Study co-author John H. Matthews, Executive Director of the Alliance for Global Water Adaptation, said, “Migrating, breeding, developing and post-breeding birds need water, but they also need good quality water. This is one of the first studies globally to show that climate change is altering water quality. If shifts in climate can alter water quality for birds, then climate change can alter our water quality too. These bird populations are the canary in the coal mine for all of us.”
The researchers examined more than a century’s worth of temperature and precipitation data across the Great Basin, which spans nearly all of Nevada, much of Oregon and Utah, and portions of California, Idaho and Wyoming. They compared the data with more than 50 years of results from the U.S. Geological Survey Breeding Bird Surveys, which began in 1968.
The research focused on waterbirds, which are species that include shorebirds, ducks, geese, swans, herons and rails. The Great Basin is a major part of the Pacific Flyway, a major north-south route for migratory birds in North America. During spring migration, more than 2 million waterfowl pass through the southern Oregon-northeastern California region of the Pacific Flyway.
Wetland Restoration improves livelihoods in developing citiesby Rob Cadmus (Ramsar Convention Secretariat), Chris Percival (The South Pole Group), and Ania Grobicki (Acting Secretary General, Ramsar Convention Secretariat)
Much of our increasingly urban world takes access to clean water for granted, viewing it as an inexhaustible resource. Yet today, hundreds of millions of people will go without clean water and one out of three people will not have access to proper sanitation (WHO & UNICEF, 2015). In 2010, more urban dwellers were without access to water services than in 2000 (De Castro Zoratto & Ivins, 2015), and it is estimated that by 2050 the global demand for water will increase by 55% (WWAP, 2015). Meeting basic water needs will continue to be a challenge.
As people have migrated from rural areas to urban centers in hope of jobs and education, cities have expanded outwards and in many cases have degraded the waterways and wetlands that surround them, resulting in polluted water with the worst conditions felt by the poor and disadvantaged. This cycle of expansion and degradation is seen throughout the world, but is particularly striking in some of the least developed countries where informal settlements and slums have sprawled faster than basic services. Nearly 900 million people will live in slums by 2020 (WHO & UN-Habitat, 2010), and in developing countries 90% of sewage is discharged untreated into water bodies (Corcoran et al., 2010). In many of these informal settlements, pollution and open sewers contaminate water, resulting in disease and deaths. The UN estimates that approximately 3.5 million people die each year as a result of inadequate water, sanitation, and hygiene (UN Water, 2013). Further, these populations are often the most vulnerable to natural disasters, food shortages, and the impacts of climate change. Read More...

The Wetland Thematic Group (CEM, IUCN) is now accepting proposed chapters to their upcoming book Wetlands at Risk
. The objective of this publication is to bring awareness about most important wetlands under risk in different world regions portraying their status, problems and conflicts related to human impacts, discussing and proposing suitable management practices and solutions for their effective recovery and conservation. Regions will be considered according to IUCN criteria
Articles submission is open for people involved in management, research, conservation, restoration and other issues related to wetland. belonging or not to UICN. Articles that do not fit the author guidelines will not be considered and received articles will be accepted after review. A final document with ISBN number will be published under pdf format and freely distributed. However, in the case of sufficient funds availability a printed copy will be published as well. Guidelines for submissions are listed below. Read More...
Wetlands: The Hidden Resource for Climate Mitigation and Adaptation
by Chris Perceval (left), Head of Strategy and Partnerships at the Ramsar Convention, and Rob Cadmus (right), Manager, Investing in Natural Infrastructure at the Ramsar Convention
The Convention on Wetlands, called the Ramsar Convention, is an intergovernmental treaty that provides the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources. The Ramsar Convention and its Contracting Parties commit to work towards the wise use of all the wetlands and water resources in their territory, through national plans, policies and legislation, management actions and public education. In this article the authors discuss the importance and hidden value of wetlands as a resource in both climate mitigation and adaptation.
Wetlands – areas of land that meet water – are among the most productive and valuable ecosystems. They are fundamentally important for supporting sustainable development and combatting climate change. Between now and the end of the year, the world’s governments will meet to discuss the global agendas for both sustainable development and climate change. They would do well to remember the contribution that these critical ecosystems can make. Read More...
