However, by 2022, the agricultural and bare land areas will have expanded by 32017 ha and 23593 ha respectively. And a decrease in vegetation area of 15462 ha. According to our field surveys, demographic pressure is diversified, with 44% of factors influencing grazing productivity coming from rainfall, 34% from agriculture, and 21% and 1% respectively from pastoral activity and bush fires. Surveys of 148 households correspond to production units.
