Italy, China ponder 2,400km canal to save Lake Chad

Italy has offered to donate €1.6m to a feasibility study into digging a 2,400-km-long canal that would channel water from the River Congo in central Africa to the much depleted Lake Chad in the Sahara.

The canal would be a navigable waterway 100m wide and 10m deep capable of carrying about 50 billion cubic metres of water a year. One idea is for a road and railway to run alongside it.

The offer was made this week by Italian Ambassador Stefano Pontesilli to the Lake Chad Basin Committee during the International Conference on Lake Chad held in the Nigerian capital Abuja.

China is also interested in participating in the scheme, and has offered to match Italy’s funding.

Some 30 million people depend on the water from Lake Chad, located at the junction of four countries, Nigeria, Niger, Chad and Cameroon. The lake shrunk from 20,000 sq km in the 1960s to just 2,000 in 2002, although it has recently increased slightly in size.

The study into the "Transaqua" project would be carried out by Italian engineer Bonifica and PowerChina. The two companies signed an agreement to cooperate on the scheme in Hangzhou last year.

Transaqua was originally suggested by Bonifica in the late 1970s, and was also championed by Nigerian engineers in the 1990s.

One version of the plan would involve damming a tributary of the River Congo in the Central African Republic and digging a 2,400-km-long canal to the River Chari, which feeds Lake Chad.

  1. I wonder what stopped this project originally? and what made them awaken this time? I don’t think it is purely political issue/s but I guess European and Middle East Food Security is the culprit!! Middle East countries are interested in turning Africa into their larder

  2. The above is an apt comment., why wait until he boat is about to sink. what will happen to the Congo.

  3. The idea is interesting, but need to clear some questions before implementation:
    1. where to bring 50 billion cubic meters of water a year, if body of lake Chad is fool of the sediments?
    2. who did monitoring of lake sedimentation during last 50 years? what is speed of sedimentation at this lake?
    2. did anyone calculate volume of sediments bringing by Congo river as year bottom deposit? How many years need to fully fulfill body lake by sediments that lake will disappear?
    3. is this volume of water will be enough to what? is it include evaporation per year?
