Target 6.5 is: “By 2030, implement integrated water resources management at all levels, including through transboundary cooperation as appropriate.” Indicator 6.5.1 tracks the degree of integrated water resources management (IWRM) implementation, by assessing the four key dimensions of IWRM: enabling environment, institutions and participation, management instruments and financing. Sustainable, integrated water resources management is vital for long-term social, economic and environmental well-being – the three pillars of the 2030 Agenda – and helps to balance competing water demands from across society and the economy. This report presents the global status on IWRM and acceleration needs to achieve target 6.5 by 2030, based on the latest data on indicator 6.5.1.
