  • Ecological function zoning of Poyang Lake wetland: a RAMSAR site in China

    Ecological function zoning involves the spatial delineation of ecological functions based on the physical environment and ecosystem service functions, as well as the demands of eco-environmental protection and socio-economic development of the area according to the theory of ecological function regionalization. In this context, we defined the boundary of Poyang Lake wetland using geographic ...

  • Poplar in wetland agroforestry: a case study of ecological benefits, site productivity, and economics

    Poplars are the major tree component of traditional agroforestry systems throughout the south temperate central area of China that includes all or portions of Jiangsu, Anhui, Zhejiang, Hubei, Henan, Shandong, and Shanxi provinces, an area of ~600,000 km2. The lack of experidmental data on the effect of various interplanting systems on crop production represents a serious gap in our knowledge, and ...

  • Water cleaning and wetland construction

    Slippery Rock University's Macoskey Center for Sustainable Systems has served as an ideal locale for the study of biological waste and wastewater concerns in Western Pennsylvania. The Center's constructed ponds, waterless composting toilet and indoor greywater treatment system produced, in 19982000, great amounts of data on ecological approaches to wastewater treatment, which need to be reviewed. ...

  • What is wetland mitigation banking?

    A mitigation bank is a wetland, stream, or other aquatic resource area that has been restored, established, enhanced, or (in certain circumstances) preserved for the purpose of providing compensation for unavoidable impacts to aquatic resources permitted under Section 404 or a similar state or local wetland regulation.  The concept has been around since the 1970’s.  In 1995 U.S. federal agencies ...

  • Water balance: case study of a constructed wetland as part of the bio-ecological drainage system (BIOECODS)

    The Bio-ecological Drainage System, or BIOECODS, is an urban drainage system located at the Engineering Campus, Universiti Sains Malaysia. It consists of a constructed wetland as a part of the urban drainage system to carry storm water in a closed system. In this closed system, the constructed wetland was designed particularly for further treatment of storm water. For the purpose of studying the ...

  • Ecological Risk Assessment

    In recent years, ecological risk assessment (ERA) has emerged as an important part of environmental protection programs. The following discussion provides a brief overview of ERA issues. What is ecological risk assessment? Ecological risk assessment is the practice of determining the nature and likelihood of effects of our actions on animals, plants, and the environment. ...

  • Wetlands International Achievements 2011 – 2013

    Our Collective Targets Wise use and restoration of 20 wetlands is linked with the development of sustainable livelihoods, resulting in a strengthened asset base for at least 200,000 people Species oriented and ecological network initiatives result in improved status of selected wetland biodiversity groups, including waterbirds and freshwater fish The status of ...

  • The economics of Ecosystems and Biodiversity for Water and Wetlands

    1. Introduction The “nexus” among water, food and energy has been recognised as one of the most fundamental relationships and challenges for society. Biodiversity and particularly wetland ecosystems are increasingly understood to be at the core of this nexus. Indeed water and wetlands are the foundation for the social, economic and environmental wellbeing of humanity across ...

  • Migratory birds - Connecting Wetlands and People

    Management of migratory species succeeds where critically important sites are well managed along flyways. Migratory waterbirds depend on a range of secure sites from their breeding grounds to staging and nonbreeding sites that they use during their annual migrations. These birds depend on a range of natural and man-made wetland habitats - many are managed as nationally protected areas, ...

  • The Economics of Ecosystems and Biodiversity for Water and Wetlands

    The Economics of Ecosystems and Biodiversity (TEEB) is an international initiative to draw attention to the benefits of biodiversity. It focuses on the values of biodiversity and ecosystem services, the growing costs of biodiversity loss and ecosystem degradation, and the benefits of action addressing these pressures. The TEEB initiative has brought together over five hundred authors and ...

  • The future of European floodplain wetlands under a changing climate

    In the future, climate change may severely alter flood patterns over large regional scales. Consequently, besides other anthropogenic factors, climate change represents a potential threat to river ecosystems. The aim of this study is to evaluate the effect of climate change on floodplain inundation for important floodplain wetlands in Europe and to place these results in an ecological context. ...

  • Linking soil process and microbial ecology in freshwater

    Abstract Soil microorganisms mediate many processes such as nitrification, denitrification, and methanogenesis that regulate ecosystem functioning and also feed back to influence atmospheric chemistry. These processes are of particular interest in freshwater wetland ecosystems where nutrient cycling is highly responsive to fluctuating hydrology and nutrients and soil gas releases may be ...

  • Constructed wetlands: a solution to water quality issues in Mexico?

    Historically, water sanitation has not been a priority for any sector of society in Mexico, and substantial technical and ecological problems exist in this country's wastewater treatment systems. Constructed wetlands (CWs) have proven to be an exceptional alternative, particularly for rural areas in developing countries. This paper identifies the status of research on CWs in Mexico, and ...

  • Emerging Models for Nitrogen Removal in Treatment Wetlands

    Engineering textbooks tell a simple story about nitrification and denitrification. Classic nitrification-denitrification theory begins with the bacterial genera Nitrosomonas and Nitrobacter performing ammonia and nitrite oxidation, respectively. Then facultative or obligate anaerobic bacteria denitrify by oxidizing organic carbon with nitrate. Recent advances in environmental microbiology have ...

  • Are constructed treatment wetlands sustainable sanitation solutions?

    The main objective of sanitation systems is to protect and promote human health by providing a clean environment and breaking the cycle of disease. In order to be sustainable, a sanitation system has to be not only economically viable, socially acceptable and technically and institutionally appropriate, but it should also protect the environment and the natural resources. ...

  • Biodiversity of the wetlands of the Kakadu Region, northern Australia

    Abstract.  The biodiversity values of the wetlands in the Kakadu Region of northern Australia have been recognised as being of national and international significance, as demonstrated through their listing by the Ramsar Convention on Wetlands. Analyses of the wetland biodiversity have resulted in the production of species list for many taxa, and some population and community-level analyses ...

  • From ecology to society and back: the (in)convenient hypothesis syndrome

    In this article, we analyse the case of the emigration and death of black necked swans in Southern Chile from a postnormal perspective. We show that in the presence of radical uncertainty, as it may happen when a socio–ecological conflict arises due to a sudden, catastrophic, shift in an ecosystem, one management approach is to consider multiple hypotheses that in turn should guide ...
