The average Brit uses 150 litres of water a day!
Although many people see bottled water as a necessity it is actually having a very damaging impact on the environment.
Flooding is not just caused by heavy rain. Both physical and human factors can influence the likelihood of flooding.
Flooding can have both positive and negative impacts. To reduce the number of negative impacts flooding can be managed through a variety of techniques.
Hard engineeringare strategies imposed on the natural environment in an attempt to control it.
Soft engineering are strategies which work with the natural environment to reduce flooding.
Water vulnerability is when people do not have good access to safe, clean water. This can make them vulnerable to a range of problems associated with poor water access.
Where there is nowhere safe and clean to go to the toilet, people are exposed to disease, lack of privacy and indignity. When communities defecate in the open, disease spreads fast and water sources are polluted. Women and girls often have to wait until dark to go to the bush or a discreet part of town to defecate, where they are at risk of attack and abuse.
Improved sanitation has proven impacts on health, quality of life and poverty reduction. However, progress in increasing sanitation coverage has been slow for a number of reasons:
•Lack of political will and institutional responsibility.
•Improving sanitation is difficult and requires people to change their behaviour.
•The health benefits are not immediately seen or always understood.
•The poorest and most marginalised people lack a voice and are often unable to invest in improving sanitation.
As demand for water hits the limits of finite supply, potential conflicts are brewing between nations that share trans-boundary freshwater reserves. More than 50 countries on five continents might soon be caught up in water disputes unless they move quickly to establish agreements on how to share reservoirs, rivers, and underground water aquifers.
