Item Acesso aberto (Open Access) Análise do custo da água virtual e a formação de valores: estudo de caso na comunidade Cristo Alves – Curuçá – PA(Universidade Federal do Pará, 2017) CEI, Joelson Carvalho; ABREU, Francisco de Assis Matos de; http://lattes.cnpq.br/9626349043103626Water is a strategic asset for the survival of mankind. Pressures from increased food production, the development of water-dependent energy sources, population growth and economic growth have boosted water consumption. Thus, the increasing demand for water and the limited possibilities to increase its supply impose new practices and management tools that promote the efficiency of water use in distribution, consumption, and the productive process and encourage the rationalization of its use. Thus, the concepts of water footprint and virtual water have been gaining prominence in the scientific scenario, given the challenge of developing water use management practices based on the promotion of water efficiency. These concepts act as indicators of the use and appropriation of water in the perspectives of production and consumption. In this context, this work aims to analyze the processes of measurement of the cost and export of virtual water by the production of orange in the community of Christ Alves in the municipality of Curuçá - Pará. The analysis will be based on the orange produced in the Christ community Alves, in the municipality of Curuçá, Northeastern region of Para. The data collection for the costs of water used in the planting and irrigation of the orange will be based on information extracted from the farmers by a semi-structured questionnaire in relation to knowledge about water resources. Scientific data from the water footprint and virtual water will be used to elaborate how these costs are measured.Item Acesso aberto (Open Access) Arcabouço geológico-geofísico da região nordeste do Estado do Pará(Universidade Federal do Pará, 2017) JORGE, Maurício Victor Elleres; ABREU, Francisco de Assis Matos de; http://lattes.cnpq.br/9626349043103626The northeastern region of the State of Pará presents great potential for the occurrence of groundwater resources. Two hydrogeological systems are present in it: Pirabas and Barreiras. From a gravimetric survey conducted in this research, associated to secondary data collected in academic works and state projects (SIAGAS-CPRM), it was possible to advance the understanding of the regional geometric arrangement that determines the spatial distribution of the sedimentary packages. Map and geological-geophysical profiles of the bouguer anomaly behavior are presented, necessary to support the presented spatial ordering. The geophysical signature of the gravity anomalies in the Bouguer anomaly map analysis revealed positive and negative regions, which are limited by gravimetric lineaments, mainly NW-SE direction. Among the structures generated, in this arrangement, stands the Graben of Bragança - Viseu, partially contained in the work area. The indication of depth presented in the gravimetric profiles, and in the constructive profiles of wells, reveal to us outstanding aspects of the geometry of the sedimentary package. The geometric model of the morphostructural configuration of uneven tectonic blocks, responsible for the regional structuring of the area and the definition of places more favorable to the encounter of the largest thicknesses of sediments, in which the mentioned hydrogeological systems are closed, is confirmed in the obtained results. Thus, the methodologies and techniques used in this work proved to be robust to understand the geological compartmentalization of the work area, with respect to the guide with a higher success rate, the location of wells, in terms of expected productivity. as an important tool for planning and managing water resources.
