Resumo: Climate change, and the rise of global temperature, is associated with an increase in the emission of Green Houses Gases (GHG) of human origin. The transport sector is one of the highest contributors to these emissions. The use of bio fuels (made from energy crops), comes forward as a contributing solution, since it leads to globally lower emissions, when compared with the use of fossil fuels. The Alqueva (Alentejo, Portugal) irrigation perimeters (built and projected) have a high potential to grow energy crops, as a basis of analysis, due to heat and water availability. The soil and weather requirements of eight cultures were analysed: Salix spp, Populus spp, Miscanthus x giganteus, Cynara cardunculus L., Arundo donax L., Panicum virgatum L., Hibiscus cannabinus L., e Jatropha curcas L.. To estimate ecological fitness, in present and in a future scenario, a system named SISAP, developed in ISA, was used. This program crosses the soil and weather requirements of crops with environmental data. Results show that all the crops analyzed grow in the Alqueva areas, with reduced to average productivity. Miscanthus x giganteus seems to be the most interesting from an ecological standpoint.
