Irrigation systems in Africa

Water supply system in Africa is still very archaic.

Many modern irrigation schemes on the continent use imported fuel-driven irrigation pump systems, which are often not replaced or repaired when they fail, due to a lack of know-how, spare parts and money. The majority of farmers still rely on less productive system of fetching water from the well.

The farmers are then forced to survive on relief food. Fuel-driven irrigation pumps should be replaced with affordable systems, which use locally-available resources or renewable energy sources. This will ensure lasting food security and sustainable development. 

It is by using the river Galilee that Israelis have transformed arid lands into productive agricultural areas, providing sufficient food for both local consumption and export. 

A simple water powered water pump use the running force of the river to lift water: The force of the river moves the waterwheel which through a system of gears, rotates the chains of containers that collect water from the river and pull it on the aqueduct situated above the river.  The system works 24H a day and no imported fuel is needed. 
Along the Athi River, between Nairobi and Mombasa, several irrigation farms could be put established, providing desperately-needed jobs and food. This would attract job-seekers and reduce migration to the capital city. 

If enough water is provided for rural communities by employing self-reliance technologies, rural-urban migration will be drastically reduced, as people will live decent, productive lives, and their work will feed the urban centres. Also, disease and hunger will be reduced, since agriculture will no longer only rely on rains.
