This document discusses a shrimp farm located in the Sahara Desert in Algeria. It describes how the farm uses biofloc technology and the salinity of groundwater to raise Pacific white shrimp. The farm covers an area of 10 hectares near Ouargla, Algeria. It uses biofloc technology which utilizes microorganisms excreted by shrimp to clean the water and provide a food source for the shrimp. This technology allows the water to be reused with only 1% replacement. The farm aims to produce 100 tons of shrimp annually. The project has invested $576 million to demonstrate that agriculture is possible in the Sahara Desert's conditions.

3. 01. Where?
▶ Sahara
• The largest hot desert in the world, and the third largest desert in the world after
Antarctica and the Arctic. Its area of 9,200,200 square kilometers is comparable
to the area of the USA.
• The desert comprises much of North Africa, excluding the fertile region on the
Mediterranean coast, the Atlas Mountains of the Maghreb, and the Nile Valley in
Egypt and Sudan.

Location of Sahara

4. 02. Why?
▶ Irrigation
• Desalination Plants
• Center pivot irrigation
• Solar power drip irrigation
• Economic profits
• Generating energy
- Scale of the investment↑
- Hard to establish the
infrastructure for all countries.
Agriculture
École nationale supérieure des mines de Saint-Étienne
For …
Different surrounding environment = Different solutions
Objectives of irrigation

5. 03. What?
École nationale supérieure des mines de Saint-Étienne
▶ Farming shrimp in Sahara!
• Ouargla (Wargla), Algeria
• Extent = 10ha (12 soccer fields)
• Using the salinity of ground water to raise
“Pacific white shrimp”
• Be able to produce up to 100 tons of shrimps in the desert
per year
• About 576 million dollars have been invested
Special example

6. 04. How?
École nationale supérieure des mines de Saint-Étienne
▶ Biofloc Technology
• Using microorganism “biofloc”, which is excreted by shrimp
• Mass of biofloc becomes food of shrimps, and it can strengthen
immunity of shrimps more than 30%.
→ It reduces cost of antibiotics and animal fodder.
• It purifies pollutants in the water in which they will cultivate the
shrimp, thus enabling them to recycle the water.
• In ordinary farms, we have to replace water ceaselessly, but biofloc
allows us to reuse 99 percent of the water except for the water
which evaporates naturally
→ It is environment-friendly technology
How to raise shrimps in Sahara
Brown
Green
1. When carbon is added, nitrogen compounds combine with it to produce flocs of
protein molecules.
2. These molecules form a floating mass called bioflocs which are dominated by bacteria.
(The production of microbial biomass, are used by the culture species as additional high
protein source.)
3. The bacteria take up ammonium from the water to produce microbial protein.
4. It removes ammonia-nitrogen from the water.

7. 05. Conclusion
▶ Imposing Restrictions
• Prohibit logging
• Limitations of Grazing
• Planting project
École nationale supérieure des mines de Saint-Étienne
Limitations
→ Global green business based on
soil geology and bioclimatology
** It is not fundamental solution to slow down the speed of desertification
VS
Once installed, it is not difficult to
maintain
Extend the scope of future
development direction of Sahara
Adaptable for specific areas
- Ground water
For the central area of Sahara,
it seems difficult to apply
- Hard to build facilities, supply
electricity and inefficient to transport
To find global solutions (sustainable…)
