Water 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.
