Assessing Jatropha Crop Production Alternatives in Abandoned Agricultural Arid Soils Using MCA and GIS

This paper discusses the assessment of various biofuel crop production alternatives on the island of Fuerteventura using Jatropha crops. It adopts an integrated approach by carrying out a multi-criteria assessment with the support of participatory techniques and geographical information systems. Sixteen production alternatives were analyzed for growing Jatropha, and the results suggest that the best alternative involves using typical torrifluvent soils irrigated with recycled urban wastewater using surface drip irrigation covering 100% evapotranspiration. It was also determined that a potential area of 2546 ha could be used for cultivation within a radius of 10 km from a wastewater treatment plant. This level of production would supply 27.56% of the biofuel needs of Fuerteventura, thereby contributing to the 2020 target of the European Commission regarding biofuels for land transport
