  10. 10. POLICY ORIENTED RECOMMENDATIONS Livestock development policies, mainly in dry sub-humid and semi-arid areas, should provide economic incentives and regulatory mechanisms to promote (and even force) tree planting in spatiotemporal designs - within the Agroforestry concept -, enhancing , in first instance, the beneficial interactions of trees with other components of the soil-plant- animal complex. National and local stakeholders involved in designing and implementing payment mechanisms for environmental services should consider Agroforestry as a viable practice of SLM which not only stop land degradation and desertification, but also enhance the protection of other natural resources. Then, land users could receive additional revenue.
  11. 11. CONCLUSIONS The implementation of silvopastoral systems - mainly with L. leucocephala - in fragile livestock agroecosystems constitute a viable Agroforestry alternative to achieve a Sustainable Land Management and, consequently, to improve animal´s nutritional status and productive performance. Farms managed under Agroforestry systems, with a tree density between 5000-6500 trees ha-1 and a limited level of supplementation, can achieve a milk yield of 7-8 kg cow-1 day-1 and a daily gain around 500-640 gr day-1, which are higher as compared to deforested agroecosystems. Under conditions of the present study, tree densities below 5000 trees ha-1 have not benefit on the foliage production and soil fertility. While, tree densities higher than 14000 trees ha-1 cause an excess of shadow affecting the botanical composition of the herbaceous strata.
