25 years ago in 1995 this day was signed the international convention to combat desertification. Armenia is one of the first countries which has become a member of the convention and which has elaborate national action programmes to combat desertification. From the desertification points of view Armenia is a vulnerable country. Desertification is characterized by degradation of land resources, biodiversity and livelihood poverty the result of which is the deterioration of social conditions. Land degradation is caused by illegal logging of forests, overgrazing of cattle, inaccurate construction, soil pollution and so on. Desertification mitigation and prevention are guarantees of country`s sustainable development.
