3. SILVOPASTORAL* Systems : Fodder production (cut-and-carry) Live-fences of fodder trees and hedges Trees and shrubs on pasture (or grazing under plantation crops) Nair (1993): AGROSYLVOPASTORAL* Systems : Woody hedges for browse, mulch, green manure, soil conservation Homegardens (involving a large number of herbaceous and woody plants and/or livestock) * A pastoral system implies LIVESTOCK
4. Examples of traditional combinations of PASTORALISM* and AGRICULTURE: East Africa – Maasai: pastoralism + sub-group of farmers Andes: agricultural and pastoral communities exploit different ecological zones (plain cultivators and Andean mountain pastoralists) Miller (1999)/1: AGROSYLVOPASTORAL* Systems: Sahel: in the sub-humid regions agriculture and grazing production systems overlap, both characterized by dispersed indigenous trees Middle East: Oasis system * Synonymous of nomadism
5. THREATENS to the SUSTAINABILITY of traditionally nomadic pastoralism: Overgrazing, deforestatio, erosion, desertification, overpopulation, break-down of sociocultural systems, encroachments of other groups. Miller (1999)/2: BENEFITS of LIVESTOCK: Pastoralism is multi-resource activity: a natural oscillation beetwen existing patterns (flexibility, adaptability, variability). Producing organic fertilizer, reducing risk in the case of crop failure, replacing mechanical power. Different livestock provide different quantities of milk (goats: milk during dry season), chickens and ducks: eggs and rapid reproduction. BENEFITS of TREES and SHRUBS: Shade for human and livestock, reducing wind speed and evapotraspiration, counteracting variability in the production of browsing, producing nutrient rich pods and leaves. Indigenous and exotic trees, shrubs and grasses with different degrees of palatability of browse (preferable) and bark (problematic), resistance to drought, ability to regenerate naturally.
6. “ The tragedy of the commons” Hardin (1968): justification for an anti-nomadic perspective and privatizations. The insecurity of land tenure is always a disincentive to tree planting, which itself may increase the security of land tenure. Pastoral modes of production proved ecologically sustainable and appropriate for millennia before the colonial era, that drastically altered the structural and political conditions for pastoralists (see also the studies concerning the commons of E.Ostrom). Land and tree tenure:

Reinforcement of the traditional land-management systems through collaboration with resource de facto users Pastoralists could utilize agroforestry to meet their social, cultural, livelihood needs.
