This system covers the extensive desert areas of the region. It contains some oasis farming and a number of irrigation schemes (notably in Algeria, Libya, Morocco, Sudan and Tunisia) where dates and other palms, vegetables, and cereals such as maize and rice are grown. Crop residues provide opportunistic grazing for the herds of pastoralists, and other fodder grows after scattered storms and in good seasons. The boundary between pastoral grazing and sparse agricultural systems is indistinct. Constraints are those already described for the component systems (pastoral, agro-pastoral and irrigated).
