The overall goal of this research subline is to contribute to soil and crop protection through the use of low-cost bioremediation technologies and the promotion of sustainable development of agricultural systems by means of ecological alternatives. This general objective is approached from a triple perspective: (i) the development of the bioremediation processes, mainly vermicomposting, that favour the biotransformation, recycling and recovery of organic wastes, as well as the development of low-cost technologies for the prevention and protection of soil against organic contaminants; (ii) the development of an integrated management of pests in agroecosystems; and (iii) the development of methods to evaluate and to maintain the biodiversity in sustainable agrosystems.
