Procedure for emergetic assessment in urban river de-pollution

Abstract

Abstract Using emergetic indicators to evaluate complex processes such as the de-pollution of urban rivers aims to contribute to better use and preservation of the resources, besides the valuation of ecosystem services provided by the water body. Within this context, we conducted a bibliometric and systematic review that shows the lack of emergetic indicators in urban river de-pollution. Thus, this work aims to propose an emergetic assessment procedure to evaluate the de-pollution process of urban rivers that allows technicians, academics, and revitalization process managers of urban rivers to improve the monitoring and decision-making directly related to the process, concluding that an emergetic assessment procedure contributes to theory to create new scientific analyses applied to urban revitalization and nature preservation processes. The emergetic assessment procedure contributes to society by improving the disposal of public resources and the effective maintenance of urban rivers that provide ecosystem services to all stakeholders (residents, grantors, and sanitation companies). In practice, the use of the emergetic assessment contributes to the monitoring from the first stages of the clean-up process, demonstrating the sustainability of the process for the adequacy of resources and maintenance of the water body that shall be cleaned.
