The socio - environmental conflicts related to water quality and quantity associated with mining in the Andean region is cause for concern. There is a role for scientific data an d social participation in mining related conflicts and the evolution to an ecosystem approach in water management, however few academic studies can be found which assess the environmental problems in the region and proposing methodologies adapted to mining contexts. The Jequetepeque river basin, located in Northern Peru, was chosen for action - research carried out from 2006 - 2011 and included a sequence of projects involving different local stakeholders (government, universities, NGOs). The application of hyd rological modeling, “smart” environmental monitoring and the use of aggregated indices on raw data for management is evaluated. The approach facilitates innovative work in the water sector, while partners that participate gain knowledge and capacities to take informed decisions related to mining and water resource management.
