  • UNEP hosts Intergovernmental Negotiations on Strengthening Science for Policy on Biodiversity & Ecosystems

    Ecosystem health and sustainability are central to the well being of human kind. Over the past 50 years, the world has suffered an estimated 60 % decline in ecosystems services and unprecedented biodiversity loss - caused by unsustainable human activities. Biodiversity loss makes ecosystems more vulnerable to shocks and disturbances, less resilient, and less able to supply humans with critical ...

  • Cement develops an appetite for C02

    Three new studies illuminate the sheer complexity of the aspect of climate science known as the carbon cycle − how carbon dioxide gets into the atmosphere and out again. Sometimes, human agency is at work, but nature takes care of it anyway – as one of the studies reveals in the case of cement, the world’s most widely-used building material. Zhu Liu, postdoctoral scholar at ...

  • Ecosystem renovation - bring it on back

    A ‘lost’ lake in Mali and a Kenyan forest that is the water tower for key rivers and lakes in East Africa are among two country projects aimed at bringing significant degraded and denuded ecosystems back from the brink. The projects are among several being drawn up and spearheaded by the UN Environment Programme (UNEP), in cooperation with governments, to demonstrate that re-investing in damaged ...

  • Ecosystem markets take off

    While global financial markets crumble, a new form of markets is on the rise. Ecosystem markets, exchanges of nature's various services, are adding new dimensions to conservation. In addition to using regulation to restrict development, more countries are turning to the invisible hand of the market to protect biodiversity, clean waterways, and fight climate change. In a nutshell, market-based ...

  • Global warming’s ecosystem double whammy

    Plants and soils act like sponges for atmospheric carbon dioxide, but new research finds that one abnormally warm year can suppress the amount of carbon dioxide taken up by some grassland ecosystems for up to two years. The findings, which followed an unprecedented four-year study of sealed, 12-ton containerized grassland plots at DRI is the cover story in the September 18 issue of the ...

  • Coastal structures change marine ecosystems

    The urbanisation of coastal areas and introduction of man-made structures, such as jetties and seawalls, are changing marine environments. A new analysis highlights the impacts of these changes on marine plants and animals and suggests options to manage the detrimental effects. Many of the world's largest cities are in coastal zones and more than 75 per cent of people are expected to live within ...

  • Climate change and the integrity of science

    We are deeply disturbed by the recent escalation of political assaults on scientists in general and on climate scientists in particular. All citizens should understand some basic scientific facts. There is always some uncertainty associated with scientific conclusions; science never absolutely proves anything. When someone says that society should wait until scientists are absolutely certain ...

  • The value and challenge of complexity science

    A compelling new book suggests a scientific revolution is needed in aid practice. But there are key challenges. Aid has had some success, helping to lift a billion people out of poverty over the past two decades. But establishing how much of a contribution it has made is more complicated. And now the challenge is how ...

  • Tidal Marshes protect aquatic ecosystems and store carbon

    A team of scientists measured nitrogen and phosphorus retention and carbon sequestration by tidal marsh soils along the Georgia coast to document the role of these wetlands in storing carbon and removing nutrients at the landscape scale. The results suggest that tidal marches protect aquatic ecosystems from eutrophication, caused by the accumulation of nutrients that disrupts ecosystems and ...

  • Marine ecosystems get a climate form guide

    The Marine Climate Change Impacts and Adaptation Report Card for Australia, and an accompanying website, will provide a biennial guide for scientists, government and the community on observed and projected impacts of climate change on marine ecosystems. 'The objective of compiling this information is to consider options available to environmental and resource managers in their response to changes ...

  • Transgenic Corn Found to Damage Stream Ecosystems

    BLOOMINGTON, Indiana, October 11, 2007 (ENS) - A widely planted variety of genetically engineered corn has the potential to harm aquatic ecosystems, finds a new study by an Indiana University professor of environmental science and his colleagues. Pollen and other plant parts containing toxins from genetically engineered Bt corn are washing into streams near cornfields and harming a ...

  • Study dispersant use and ecosystem impacts of dispersed oil

    Last Thursday, over fifty experts and practitioners from government, academia and industry finished a two-day meeting looking at the potential long-term impacts of the prolonged use of large volumes of dispersants in the Deepwater Horizon oil spill response efforts in the Gulf of Mexico. EPA and NOAA scientists are conducting rigorous ongoing monitoring and analysis of the effectiveness and ...

  • SETAC Europe addresses global ecosystem health in Gothenburg

Nanotechnology’s impacts on the environment, risks from new pharmaceuticals, effects of contaminants at the molecular level, polar ...

  • Healthy Ecosystems Key to Better Food Security

    Today the United Nations Environment Programme (UNEP) and the Food and Agriculture Organization (FAO) signed a memorandum of understanding (MoU) that is set to ensure better support for the functioning of critical ecosystem services that underlie food security. "Healthy ecosystems are the lifeblood of food security, especially in developing countries, where a majority of people ...

  • Mountain ecosystems get boost from Rio+20

    Rio+20 has disappointed most observers. But it has created opportunities for constructive work in a few areas, says Joydeep Gupta, writing on the website The Third Pole. During the UN Conference on Sustainable Development (Rio+20) last week (20-22 June), country blocs protected their national interests, interest groups had mixed success, developing countries wanted money and richer countries ...
