Access to clean water is the foundation of
all development. The lack of water is therefore an often
insurmountable obstacle to helping oneself. You can't
grow food, you can't build housing,
you can't stay healthy, you don't go to school and you can't keep
working. Without clean water, poverty is
inevitable.

The access to drinking The access to drinking waterwater
Water resources are sources of water that are useful or potentially useful to humans. Uses of water include agricultural, industrial, household, recreational and environmental activities.
Virtually all of these human uses require fresh water.
The remaining unfrozen freshwater is mainly found as groundwater, with only a small fraction present above ground or
in the air.
Fresh water is a renewable resource, yet the world's supply of clean, fresh water is steadily decreasing. Water demand
increases faster and faster in many parts of the world as the world population continues to rise.
Awareness of the global importance of preserving water for ecosystem services has only recently emerged as, during the 20th century, more than half the world’s wetlands have been
lost along with their valuable environmental services.
Where is water in Africa?There are many rivers in Africa, even if the most
important is the Nile, situated in the North East. We also find the Zambeze, the Congo, the Niger and the Senegal, in their respective countries.
Access to drinking water
water in water in Africa…Africa…
What is the problem?Members of an African family
have from 10 to 40 liters of water per day to live, while
Europeans families consume about 500 liters!
In Africa, the problem of the water took a politic dimension
because of the conflicts due to the division of territorial
waters. It becomes more an more serious with the arrival of the global warming, which
brings less an less rain on this arid continent.
With the lack of water, African population begins to become thirsty, and the associations
are trying to convice UNESCO to solve the problem, the
quicklest possible.
Fourteen countries of Africa already suffer from the lack of water, but this number will increase.
In 2050, Africa will support two billion inhabitants, and it’s important to find a solution now how to feed this future
population. Most of the water is used for human needs
For this, we will have to manage the water resources the best as we can.
In the future…
‘Product more, with less water’ is one of the best ways to solve the problem. Less than 10% of the lands are used in Africa. By using all the rest with irrigation, we’ll be able to use and transport water easily all over Africa.New tecnics in agriculture, expensive but efficient, should also permit to restrict the consumption of water.
Drought in AfricaDroughts are frequent and
serious in Africa, especially in the region above the huge desert, the Sahara.
The extreme fragility of African lands in front of the precipitations, and their lack of capacity to keep humidity create an arid climate. Africa has also much less precipitations than the other continents, which continue to decrease, which makes it worse.
The drought makes the
harvest bad, or slows them down,
which raises up the lack of food in
Africa. It also obviously creates the
problem of drinking water there.
Illnesses, the worst consequenceNearly half of the population is affected by one of the six
illnesses linked to water: cholera, Dracunculose (worm’s illness), paludism, the Nile’s virus and others. The lack of preparation, help and hygiene increases their propagation. The hygiene is also a big probleme there, which continues to worsen. This is one of the cause of these epidemics.
For example, in South Africa, about 10 000 people are affected of the cholera, and each day,
650 of them die of diarrhea.
Unfortunately, the majority of
the deaths caused by paludism
also happen in Africa. This illness
slows down the development
and needs huge financial helps.
