Silvopastoral systems to promote forest protection in Colombia


Published on

Julián Chará, Coordinator of Center for Research on Sustainable Systems of Agriculture Production (CIPAV) presented the urgency to promote silvopastoral systems in Latin America, in particular in Colombia. “CIPAV advocates the Intensive Silvopastoral Systems (ISS) because it increases efficiency of biological processes by combining fodder shrubs, pastures and timber trees” said Chará.

Land use efficiency• Average annual per hectare stocking rate: 0.59 animals• Average annual per hectare productivity: – 19.9 kg of beef – 89.7 L of milk Los Santos province, Arco Seco region, Panama Photo: Fernando Uribe • Minimum animal loads • Low per animal and per hectare production indexes FAO, 2006 • Meager contributions to rural employment
  7. 7. Livestock in a changing world• Ensure the provision of good quality food for a growing population• Reduce the impact on the environment – Improve biodiversity – Reduce deforestation and promote restoration – Reduce water pollution and improve watershed regulation – Reduce GHG emissions – Provide environmental services• Revert soil degradation• Be resilient to Climate Change• Be respectful with local culture• Produce timber and other forest products• Increase animal welfare
  8. 8. Cattle ranching can be:• Conventionally managed: Efficient tool for ecosystem degradation.• Sustainably managed with silvopastoral systems: Tool for rehabilitating degraded lands.• Silvopastoral systems integrated with connectivity corridors and protected areas: Part of a strategy for the ecological restoration of agricultural landscapes.
  9. 9. Silvopastoral Systems - SPS• Agroforestry arrangements that combine fodder plants, such as grasses and leguminous herbs, with shrubs and trees for animal nutrition and complementary uses. Pezo & Ibrahim, 1998; Harvey 2004

  11. 11. Intensive silvopastoral system ISS• A system that can be directly grazed by livestock. It combines: – Fodder shrubs planted at high densities (>10,000 plants ha-1), intercropped with – highly-productive pastures, and – 500 timber trees planted in east-west lines to minimize shading.
