Global Water Report Identifies Tourism Growth as Part of the Problem

=========

Bangkok, 24 September 2012 (UNEP Media release and Travel Impact Newswire) – A study of almost 200 major international water-related projects over the past 20 years has identified a suite of existing and emerging challenges and how science can offer remedies. The report also clearly identifies tourism growth as being part of the problem.

The Global Environment Facility (GEF), the largest public funder of projects to improve the global environment and promote sustainable development, partnered with the United Nations University and the United Nations Environment Programme (UNEP) to extract lessons from a portfolio of major transboundary water projects involving investments of more than US$7 billion.

Insufficient and disjointed management of human demands on water and aquatic systems has led to situations where both social and ecological systems are in jeopardy and have even collapsed, says the report. River basins in particular are set to experience growing pressures due to urbanization, rising water scarcity and poor water quality.

Says the report, “Growth in the global population and the increasing demand for natural capital and ecosystem services (e.g., water for human consumption and irrigation, transport along rivers and seas, fish and aquatic plants and algae, waste disposal, renewable energy, recreation and tourism) is putting huge multiple pressures on aquatic systems.”

Investing in science, in order to identify emerging issues and track trends relating to the use of water resources, can help to reduce such risks, according to the study. Links between science and policymaking also need to be strengthened.

Several success stories of research investments that paid rich dividends are also highlighted in the report.

These include efforts to rid Lake Victoria of alien water hyacinths, where an unsuccessful project using harvesting and chopping machines was replaced with biological control of the hyacinths using a weevil. The GEF-backed approach yielded immediate positive results for biodiversity and local communities.

The new report, Science-Policy Bridges over Troubled Waters, synthesizes findings of over 90 scientists worldwide assigned to five GEF International Water Science (IW:Science) working groups focusing on groundwater, lakes, rivers, land-based pollution sources, and large marine ecosystems and the open ocean.

According to the report: “The consequences of poor decision-making are dire: we face a ‘water bankruptcy’ in many regions of the world with implications for food and energy security, adaptation to climate variability and change, economic growth and human security challenges.”

The report was launched on the opening day of the GEF International Waters Science Conference held in Bangkok, Thailand. The conference aims to set priorities for international waters science over the next decade and to enhance the use of science in GEF projects and beyond.

Other key findings include:

•  Levels of dissolved oxygen levels in marine areas (a critical ecological indicator) have dropped significantly over a relatively short time.  In 2008, over 400 marine dead zones were known to span a total area of more than 245,000 square kilometers.

• The report also highlights a major increase of stored heat in oceans. Such changes could have negative impacts on ecosystems, sea levels and human livelihoods.

• The management of groundwater remains isolated from other ecosystems, and the  limitations in recharge capacity of aquifers are not well understood by decision makers.

Zafar Adeel, director of the United Nations University International Network on Water, Environment and Health (UNU-INWEH), and a report co-author, said: “This study underscores how often early ‘alarm bells’ with respect to emerging issues can be heard and must be heeded.  The report offers helpful recommendations to the GEF to foster this process.”

Ivan Zavadsky, GEF’s International Waters Focal Area Coordinator, notes that over 20 years GEF had catalyzed the largest investment of its kind in human history.  GEF’s $1.3 billion catalyzed a total of $7 billion of investment in managing shared waters – fresh and marine – in almost every part of the planet, above and below its surface.

“One of the principal lessons from this review is that science must play a more central role in determining the nature and priority of these investments,” he said.  “This examination of work in the recent past contributes significant insights into the challenges ahead.”

“World leaders agreed at the Rio+20 summit in June to strengthen the science-policy interface and to foster international research collaboration on sustainable development. This is especially important in respect to water resources at a point in time of unprecedented pressures from climate change and urbanization to pollution and over extraction,” said UN Under-Secretary-General and UNEP Executive Director Achim Steiner.

“Some positive steps are being made, however. UNEP’s recent Global Environment Outlook-5 report analyzed progress on 90 key environmental goals. It found that significant progress is being made in improving research to reduce pollution of the marine environment. These achievements need to be registered across the water management challenge including lakes, rivers and aquifers in order to bring water into the centre of development plans en route to an inclusive Green Economy”, added Mr Steiner.
