Decreased water availability and quality due to pollution from mining, agro-industrial activity and urban growth is the main reason for increased pressure on the basin's water resources. Public misinformation regarding the actual state of the basin has often hindered cooperation among sectors.
GWP Peru and the Sociedad Geográfica de Lima organised a seminar to provide stakeholders with a scientific overview of water resources in the basin over the last 20 years. Consensus was reached on the need to consolidate the institutional role of the basin's Water Resources Council, created in July 2011, to involve all stakeholders in the planning, coordination and harmonisation of the sustainable use of the basin's water resources. Knowledge exchange and discussion will reduce the level of tension and provide input for the formulation of a water management plan for the basin.
