LONDON (Reuters) - Scientists from 15 countries are calling for a better political response to the provision of water and energy to meet the challenge of feeding a world of 9 billion people within 30 years.

The joint statement by some of the world's leading science academies was issued on Thursday ahead of the G8 summit in the United States. It is part of the annual lobbying effort aimed at focusing the attention of world leaders on issues the scientific community regards as crucial.

For the first time, the scientists argue that looming shortages in water and energy supplies should be treated as a single issue.

"Major stresses on availability of energy and water are already being felt in many countries and regions and more are foreseeable," the joint statement said.

Fossil fuel, nuclear and hydropower are still providing the bulk of the world's energy and they all rely heavily on the supply of water for cooling, running steam turbines or direct power generation. Conversely, large amounts of energy are used in pumping, purifying and desalinating water around the globe.

"Without considering water and energy together, inefficiencies will occur, increasing shortages of both," the statement warns. Politicians should pursue policies that integrate the two and emphasise the need for conservation, efficiency and cooperation across national borders.

DISASTERS CERTAIN TO HAPPEN

The world also needs to increase its resilience against disasters like those which result from tsunamis, earthquakes and levees that fail in the face of rising sea levels.

"Disasters are absolutely certain to happen," Michael Clegg of the U.S. National Academy of Sciences told Reuters, adding growth in the global population, from 7 billion now, was focused on coastal areas that are more vulnerable, making it "more important that we design for resilience."

The scientists said global annual losses from natural disasters exceeded $200 billion in 2005, 2008 and 2011 but loss of life was generally much lower in developed countries.

Governments should focus efforts on improving public health systems, strengthening building standards and better information technology that enables faster warnings and response.

Signatories of the statement are from the leading science academies in the United States, Russia, China, Britain, Brazil, Canada, France, Germany, India, Indonesia, Italy, Japan, Mexico, Morocco and South Africa.

They also call for better measurement of planet-warming greenhouse gas emissions and more solid data country by country on natural resources like forests, which absorb some of the most damaging carbon emissions.

"More accurate and standardized methods for estimating human and natural sources and sinks of greenhouse gases are needed as a prerequisite for an international climate treaty and to determine the effectiveness of national emission-reduction programmes," they said.

Clegg said that despite the widespread acceptance of the need to reduce greenhouse gases, there is still a lot of uncertainty about, and a lack of standardisation in, the methods for measuring those emissions.

"There is a great need to develop more accurate approaches," he said, adding that it was a fundamental building block for the world's response to climate change but "getting a correct measurement ... is challenging."

The statement urges politicians to "give greater consideration to the vital role science and technology could play in addressing some of the planet's most pressing challenges".
