01. Where?

▶ Sahara• The largest hot desert in the world, and the third largest desert in the world af-

terAntarctica and the Arctic. Its area of 9,200,200 square kilometers is compara-ble to the area of the USA.

• The desert comprises much of North Africa, excluding the fertile region on theMediterranean coast, the Atlas Mountains of the Maghreb, and the Nile Valley inEgypt and Sudan.


Location of Sahara

02. Why?▶ Irrigation• Desalination Plants

• Center pivot irrigation

• Solar power drip irrigation

• Economic profits

• Generating energy

- Scale of the investment↑- Hard to establish the infra-structure for all countries.

Agriculture


For …

Different surrounding environment = Different solu-tions

Objectives of irrigation

03. What?


▶ Farming shrimp in Sa-hara!• 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

04. How?


▶ Biofloc Technol-ogy• 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 fod-

der.

• 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 addi-tional high protein source.)3. The bacteria take up ammonium from the water to produce microbial pro-tein.

4. It removes ammonia-nitrogen from the water.

05. Conclusion

▶ Imposing Restric-tions• Prohibit logging

• Limitations of Grazing

• Planting project


Limitations

→ Global green business based on soil geology and bioclimatology

** It is not fundamental solution to slow down the speed of desertifi-cation

VS

Once installed, it is not difficult to maintain

Extend the scope of future de-velopment 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 elec-tricity and inefficient to transport

To find global solutions (sustain-able…)
