A recent survey confirms that African nations are home to the world’s most vulnerable water supplies, and face substantial risks from climate change and population growth.

British consultancy group Maplecroft crafted a “water security risk index” of 165 nations around the world based on criteria such as access to drinking water, per capita demand and dependence on water from rivers which first travel through other neighboring nations.

The survey showed primarily African and Asian nations had the most vulnerable supplies, with Somalia, Mauritania, Sudan, Niger and Iraq leading the list of “riskiest nations.”

However, poor countries are not the only ones facing increased water risk, noted Anna Moss, an author of the study.  Regions of the United States and Australia are also at high risk levels., as are European countries like Bulgaria, Belgium and Spain.

On the other end of the spectrum, the most secure water supplies can be found in Iceland, Norway and New Zealand.

The largest source of renewable energy generation in the world is hydropower, accounting for 20% of global electricity supply.

According to a recent report from Global Data, total hydropower capacity has increased from 695.8 GW in 2001 to 888.8 GW in 2009 – a CAGR of 3.1%. This dramatic increase resulted mainly from new Chinese installations, many of which came online in 2004.  Favorable government subsidies have also allowed the hydro sector to continue its growth.

Although fossil fuels are still the dominant source of energy production worldwide, over 60 nations now rely on hydropower to satisfy 50% or more of their domestic energy needs.

Global Data predicts installations of small hydro plants will grow to 201GW by 2020, and predicts smaller installations will be an important source of growth for the industry.

The United Kingdom’s offshore renewable energy capacity could one day generate as much electricity every year as would one billion barrels of oil, according to a recent report from the Offshore Valuation Group.

The Group projects that utilizing just one third of the available wind and tidal resources off the UK coast could eventually transform the nation from a net importer to a net exporter of electricity by 2050.  At the same time, deploying these resources would result in a savings of 1.1 billion tons of carbon dioxide emissions and create infrastructure with a positive net present value of £35 billion.

“We have long been saying that the North Sea will become the Saudi Arabia of wind energy,” says Peter Madigan, head of offshore renewables at industry advocacy body RenewableUK.

The amount of water used to produce food and goods imported by developed countries is worsening water shortages in the developing world, a report says.

The report, focusing on the UK, says two-thirds of the water used to make UK imports is used outside its borders.

The Engineering the Future alliance of professional engineering bodies says this is unsustainable, given population growth and climate change.

It says countries such as the UK must help poorer nations curb water use.

“We must take account of how our water footprint is impacting on the rest of the world,” said Professor Roger Falconer, director of the Hydro-Environmental Research Centre at Cardiff University and a member of the report’s steering committee.

“If we are to prevent the ‘perfect storm’, urgent action is necessary.”

The term perfect storm was used last year by the UK government’s chief scientist, Professor John Beddington, to describe future shortages of energy, food and water.

Forecasts suggest that when the world’s population soars beyond 8bn in 20 years time, the global demand for food and energy will jump by 50%, with the need for fresh water rising by 30%.

But developing countries are already using significant proportions of their water to grow food and produce goods for consumption in the West, the report says.

“The burgeoning demand from developed countries is putting severe pressure on areas that are already short of water,” said Professor Peter Guthrie, head of the Centre for Sustainable Development at Cambridge University, who chaired the steering group.

“If the water crisis becomes critical, it will pose a serious threat to the UK’s future development because of the impact it would have on our access to vital resources.”

Key to the report is the concept of “embedded water” – the water used to grow food and make things.

Embedded in a pint of beer, for example, is about 130 pints (74 litres) of water – the total amount needed to grow the ingredients and run all the processes that make the pint of beer.

A cup of coffee embeds about 140 litres (246 pints) of water, a cotton T-shirt about 2,000 litres, and a kilogram of steak 15,000 litres.

The average UK consumer uses about 150 litres per day, the size of a large bath.

Ten times as much is embedded in the British-made goods bought by the average UK consumer; but that represents only about one-third of the total water embedded in all the average consumer’s food and goods, with the remainder coming from imports.

The UK is not unique in this – the same pattern is seen in most developed countries.

The engineering institutions say it means nations such as the UK have a duty to help curb water use in the developing world, where about one billion people already do not have sufficient access to clean drinking water.

UK-funded aid projects should have water conservation as a central tenet, the report recommends, while companies should examine their supply chains and reduce the water used in them.

This could lead to difficult questions being asked, such as whether it is right for the UK to import beans and flowers from water-stressed countries such as Kenya.

While growing crops such as these uses water, selling them brings foreign exchange into poor nations.

In the West, the report suggests, concerns over water could eventually lead to goods carrying a label denoting their embedded water content, in the same way as electrical goods now sport information about their energy consumption.

The Engineering the Future alliance includes the Institution of Civil Engineers (ICE), the Royal Academy of Engineering (RAE) and the Chartered Institute of Water and Environmental Management (CIWEM).

A veritable environmental catastrophe is developing in the Gulf waters around the Louisiana coastline following a fatal explosion on an offshore BP oil rig.

Last week’s incident left eleven workers missing and presumed dead,  and broke open a deep-sea pipe, which is currently leaking an estimated 5,000 barrels a day into the ocean.  Coordinated efforts from the U.S. Coast Guard and BP – which as leaser of the rig is responsible for all clean-up costs – have not succeeded in containing the oil slick.  Today’s reports indicate that strong winds are pushing the oil towards the shoreline, which is home to a variety of sensitive ecosystems and species that would all be in danger if the oil were to reach land.

The consequences of this major spill could spell disaster for President Obama’s proposal to expand offshore drilling in the United States, which he was offering as a way to encourage bipartisan support for a more far-reaching climate bill.  The President has ceased issuing new offshore drilling leases until a deeper investigation into this explosion is conducted.

Carbon dioxide emissions are changing the the chemistry of the world’s oceans at an “unprecedented rate and magnitude.”  The current rate of change “exceeds any known to have occurred for at least the past hundreds of thousands of years,” says the National Research Council in a recent report.

Oceans are one of the world’s largest “carbon sinks,” storing about one-third of all CO2 emissions.  However, when CO2 is stored in the ocean, it reacts with seawater to form carbonic acid.  Unless emissions of carbon dioxide are limited, scientists warn that the ocean will grow more and more acidic.  Coral reefs and marine life are especially sensitive to the pH balance of the ocean, and increased acidification could have catastrophic consequences, such as the creation of ocean “dead zones” devoid of sea life.

The National Research Council’s data shows ocean acidity has increased 0.1 points (out of a 14 point pH scale).  This data indicates that ocean chemistry has changed more since the Industrial Revolution than at any other point over the last 800,000 years.

New Delhi, 4 February 2010 – The World Business Council for Sustainable Development (WBCSD) today launched the Vision 2050 report ( 2.6 MB), a study that lays out a pathway leading to a global population of some 9 billion people living well, within the resource limits of the planet by 2050. The report, released at the World CEO Forum in New Delhi, India, was compiled by 29 leading global companies representing 14 industries.

This work results from an 18-month combined effort with CEOs and experts, and dialogues with over 200 companies and external stakeholders in some 20 countries.

The report presents new opportunities for business in a broad range of business segments with the foresight to lead their societies on a sustainable business development agenda. Entitled Vision 2050: The new agenda for business, the report “lays out the challenges, pathway and options that business can use to create an opportunity-rich strategy, both regionally and globally, that will lead to a sustainable world,” said Dr. Mohammad A. Zaidi, Executive Vice President and Chief Technology Officer of Alcoa, who led the project as one of four co-chairs.

“The world already has the knowledge, science, technologies, skills and financial resources needed to achieve Vision 2050. However, concerted global action in the next decade will be required to bring these capabilities and resources together, putting the world on the path to sustainability,” explained WBCSD President Bjorn Stigson.

The publication outlines a future in which 9 billion people live well, enjoying health, food, shelter, energy, mobility, education and other basics of life. Syngenta CEO, Michael Mack added that “humanity has largely had an exploitative relationship with our planet; we can, and should, aim to make this a symbiotic one.” In the Vision 2050scenario, global society attains this standard of living at a sustainable rate, without further harm to biodiversity, climate and ecosystem services.

The report states that the world already has the resources to achieve Vision 2050,but there is a catch: “The radical changes highlighted in Vision 2050 demand a different perspective from business leaders, requiring them to rethink how they operate to stay on-track for a sustainable future,” added Samuel A. DiPiazza Jr., former CEO and Chairman of PricewaterhouseCoopers. This includes a radical transformation of global markets, governance and infrastructure, and a re-thinking of our ideas of growth and progress.

Vision 2050 spells out the “must haves” – the things that must happen over the coming decade to make a sustainable planetary society possible. These include incorporating the costs of externalities, starting with carbon, ecosystem services and water, into the structure of the marketplace; doubling agricultural output without increasing the amount of land or water used; halting deforestation and increasing yields from planted forests: halving carbon emissions worldwide (based on 2005 levels) by 2050 through a shift to low-carbon energy systems and improved demand-side energy efficiency, and providing universal access to low-carbon mobility.

As part of this transformation, Vision 2050 calls for a new agenda for business: to work with government and society worldwide to transform markets and competition. “Sustainability will become a key driver for all our investment decisions,” added Idar Kreutzer, CEO of Storebrand and another project co-chair. New rules for markets will reframe environmental challenges as economic challenges, driving innovation and competition in the direction of sustainability and away from resource- and energy-intensive production. Rationalizing prices to include such externalities as climate and biodiversity impacts will make corporate environmental efficiency a true competitive advantage across all industries and regions.

Business will lead market change by doing what business does best: forming partnerships, creating efficiencies and competitive advantage, seizing opportunities and meeting customer needs. At the same time, a shift toward sustainability will trigger trillions of dollars in new investments in infrastructure, technology and human services, creating new opportunities for business to thrive and grow. A recent study commissioned for this project with PricewaterhouseCoopers and released today indicates that this investment could reach US$ 3-10 trillion per annum in 2050.

Vision 2050, with its best-case scenario for sustainability and pathways for reaching it, is a tool for thought leadership, a platform for beginning the dialogue that must take place to navigate the challenging years to come. “It is hoped that the Vision 2050 work will be used for many years to come. It is designed to be a platform for companies when deliberating strategies and for dialogue with governments and society about how to realize the sustainable future,” concluded Per Sandberg, Project Director for Vision 2050.
