Lógica para Modelos de Integração de conhecimentos para auxílio à decisão - plantios florestais ecológico-econômicos em zonas de recarga de aqüíferos

Logic Models for Integration of Knowledge to Aid Decision - Ecologic and Economic Forest Plantations in Areas of Aquifer Recharge. The Agrarian and Environmental Geosciences imply the integra- tion of several sciences and fields of knowledge in order to assist farming, forestry and animals' bringing. To integrate those sciences and knowledge into a model it is necessary to bring conservation practices not only to the agronomical practices but at the same time into geo-ecological administration of watersheds. The interconnection of those sciences demands the organization of: (1) knowledge bases (2) a logical articulation system for these cog- nitive bases (3) logic models of natural processes and technology and (4) a prevision and control system of even- tual anthropic-derived impacts in underground water recharge zones, water circulation, water quality and terrain stability. For the act of decision the central challenge is the internalization of "the cross-cutting aspects of decision" derived from the various sciences, natural systems and security issues. Four geo-environmental questions are cen- tral to the whole process of decision making, for the proper integration of practical knowledge, which involves the determination of the: (1) adequate parameters, (2) structural conditioning factors, (3) geodynamic factors, and (4) terrain/ecosystems susceptibility to anthropic interventions. The logical steps become thus evident for the design of decision making supporting systems, which will deal with themes involving sensible areas in watershed.
