The fight against desertification is a necessity for the protection of socio-economic infrastructures in Mauritania: a country whose area is a three-quarters desert. The phenomenon of silting, which is very acute in the country, is now a threat for:
- Urbanization and villages
- Agricultural and pastoral areas
- Communication routes (tracks, rivers, paved roads).
The best-known practices in the fight against desertification in Mauritania carried out by our initiative, “Nouakchott Association Deserves a Tree”, are as follows:
1. Mechanical stabilization of dunes
Simple techniques that are cheaply and easily reproducible by the population, were applied using branches of vegetation such as:
- Palm leaves;
- Prosopis juliflora;
- Balantites aegyptica;
2. Biological fixation (fixation of plants and plantations)
The selection of fast-growing species suited to the climate and soil conditions of our ecosystem will be a priority.
The following species are generally used for this activity. The focus is on local species, among which we may cite:
- Ziziphus mauritiana
- Acacia Senegal
- Panicim turgidum
In Mauritania, one can generally encounter three major forms of silting, namely:
- Sheet erosion
- Simple barchan dunes
- Joined barchan dunes.
The above is a brief description of what I want to share with you. Thank you and see you soon.
