Water Supply in Developing Countries
The United Nations General Assembly declared the years 2005 to 2015 an International Decade for Action ‘Water for Life’.
The primary aim of the ‘Water for Life’ decade is to help progress international commitments made on water and water-related issues by 2015.
These commitments include a Millennium Development Goal target to reduce by half the proportion of people without access to safe drinking water by 2015 and to stop the selfish use of water resources that could not be maintained in the longer term.
The UK Government Department for International Development manages Britain’s aid to developing countries. It has committed its support to the UN Millennium Development Goals.
1) Sanitation and a safe, clean water supply close to people’s homes brings benefits which go way beyond the expected improvements to health and the reduction in time spent collecting water.
2) Water, sanitation and hygiene education when combined provide the foundation for all other development and is key to reducing poverty.
1.1 billion people in the world do not have access to safe water – roughly one sixth of the world’s population.
2.6 billion people in the world do not have access to good enough sanitation – roughly two-fifths of the world’s population.
1.8 million children die every year as a result of disease caused by unclean water and poor sanitation. This equates to some 4900 deaths a day.
The number of deaths caused by diarrhea can be reduced by an average of 65% where there is combined provision of safe water, sanitation and hygiene education.
At least 90% of drinkable water in the world is underground. This water is increasingly under threat from being steadily reduced and from being polluted.
Since 1950 the world population has doubled but water consumption has increased six-fold.
The average person in the developing world uses 10 litres of water a day for their drinking, washing and cooking. This is the same amount used in the average flush of a UK toilet.
40 billion working hours are spent carrying water each year in Africa.
The weight of water that women in Africa and Asia carry on their heads is commonly 20kg, equal to the average UK airport luggage allowance.
Over 80 countries with 40% of the world’s population are subject to water shortages.
