Introduction

There are more than one billion people who lack access to a steady supply of clean water. There are 2.4 billion people - more than a third of the world's population - who do not have access to proper sanitation. The results are devastating:

Access to water and sanitation, so crucial for human well-being and development, has now become a priority for the international community. To underscore the need for immediate action, the United Nations has designated 2003 as the International Year of Freshwater.

Although essential, freshwater is unevenly distributed: while 70 per cent of the world's surface is covered by water, 97.5 per cent of that is salt water. And of the remaining 2.5 per cent that is freshwater, almost three quarters of that is frozen in ice caps.

While in most regions there is still enough water to meet everyone's needs, it needs to be properly managed and used. In today's world, much water is wasted or used inefficiently, and often demand is growing faster than the supply can be replenished by nature. While competition over water resources can be a source of conflict, history has shown that shared water can also be a catalyst for cooperation.

Key statistics

Meeting the Global Targets

The 147 world leaders who attended the UN Millennium Summit in 2000 adopted the target of 2015 for halving the proportion of people who are unable to reach or to afford safe drinking water. At the 2002 World Summit on Sustainable Development in Johannesburg, countries agreed to a parallel goal to halve by 2015 the proportion of people without proper sanitation.

The cost of upgrading water supply and sanitation to meet basic human needs in developing countries is estimated to run about $20 billion a year - current spending in those countries totals about $10 billion each year.

Estimates for the level of global investment required in all forms of water-related infrastructure vary widely, although there is wide agreement that the present investment level of $70-80 billion a year needs to be substantially increased. According to some estimates, up to $180 billion is required annually.

While there is agreement on the urgent need to improve water management, there are policy differences regarding how best to do this. Some contend that access to clean drinking water and sanitation is a human right for which governments are obligated to provide services. Others maintain that water is an economic good that should be provided in the most cost-effective way, including market- driven schemes and privatization of certain components of water delivery as options. Many governments have pursued a hybrid approach.

Countries that have concentrated efforts on improving access to water and sanitation have made progress. In South Africa, for example, 14 million people out of a total population of 42 million lacked access to clean drinking water in 1994. But in seven years, South Africa has halved the number of people who lack access to safe water - ahead of schedule. If the present targets are met, South Africa aims to provide everyone with clean drinking water and sanitation by 2008.
