Just reaching to our knees ! : Young Prosopis treated with TC in presence of the Minister of Public Health of the R.A.S.D. (center) and the Representative of Unicef Algeria, Mr. Raymond Janssens (right).
In 2005, Unicef Algeria invited me as a scientific consultant to study possible improvement of the living conditions in the refugee camps of the Sahraouis people in Southern Algeria (Sahara desert), looking for ways to enhance local food production. The main objective was to look for new possibilities to grow vegetables in small family gardens in the refugee camps in the desert with a minimum of brackish water, taken from the subsoil.

Nice Opuntia plantation, excellent yield in a short period
Planting spineless varieties of Opuntia can be very rewarding, not only to combat desertification, but also to produce fodder for animals. These varieties are growing quickly with a minimum of water in the drylands, like the ones in the very dry Nordeste of Brasil (see pictures).
Rows of cacti contribute to limit soil erosion
Cacti normally have a wide appeal to growers of ornamental plants, but they have only few economic uses. However, many cacti produce edible fleshy fruits (raw, jam, syrup). Some species are used in living hedges or even for furniture. Commercial plantations of the “prickly pear” Opuntia are found in Brasil, Mexico and California.
Rows on the contour lines
The disk- or racketlike, superposed parts of the Opuntia stems can be used as fodder. Goats, sheep and cows eat the fresh disks, cut into slices. One can also have the sliced disks sundried, grinded to flour and mixed with a bit of water for animal consumption.

An interesting experiment
In May 1995 an experiment was set up in Zanona (Cadiz/Andalusia/Spain) to show the effect of the soil conditioner TerraCottem (TC) on seedlings of conifers.
A number of seedlings was acquired in a nearby nursery. Half of them were kept as control plants, the other half were treated with TerraCottem soil conditioner (see http://www.terracottem.com) at a dosage of 5 g TC per kg of potting soil. All plants were watered in the same way (all the same day, all the same small volume of water to create a certain hydric stress for the seedlings under very dry conditions in the area).
