SUAREZ, J  y  MARTIN, G. J. Agroenergy production from biomass in integrated agroforestry systems: an alternative to achieve food security and environmental protection. Pastos y Forrajes [online]. 2010, vol.33, n.3. ISSN 0864-0394.

The objective of this paper is to offer considerations about agroenergy production from biomass in integrated agroforestry systems. At present, worldwide, marked by a group of hazards that threaten human existence, there is a challenge mainly in the rural context: how can the coexistence of agroenergy, food security and environmental protection be achieved?, in the presence of climate changes, environmental degradation, food crises and the growing biofuels vs food contradiction, generated by a senseless policy for obtaining first-generation agrofuels from large extensions of food monocrops, which is morally rejectable. Biofuels are also considered an ecological alternative to fossil fuels, because of their reduction capacity in the emission of greenhouse gasses and because they promote the development of rural communities in southern countries; this is enhanced in integrated agroforestry systems, in which biofuels, of first as well as second generation, can be produced, especially with the application of the concept of biorefinery which allows converting biomass into many products, which total added value can be higher than the one generated by fossil fuels. International projects, which promote integrated and sustainable food and energy production in the context of agroforestry integrated systems, at local scale, contribute to this purpose. The authors consider that the execution of projects and experiences about agroenergy has the main objective of achieving energetic sustainability and food security at local scale, in rural areas, taking into account environmental protection.
