Geographic scope: National

Title: Water forever for Abancay and Communities: Developing strategies for urban resilience to climate change in the Mariño micro-basin

Countries involved: Peru

Objective: The project helps to ensure the future availability and the responsible and equitable use of water for women and men in the city of Abancay and communities of the Mariño micro-basin, through a sustainable investment mechanism in natural infrastructure, strengthening of local capacities, optimised and resilient demand, multi-actor governance and generating replicable learning experiences.


  • Supply: Implemented a sustainable investment mechanism (“MRSE Mariño”) to ensure the supply of water, through measures for conservation, recovery and restoration of natural infrastructure in the watershed.
  • Demand: Optimised water demand, through monitoring and control of water losses, raising awareness among users and integrating the reduction of climate risk in the service.
  • Governance: Strengthened and consolidated governance spaces for IWRM (Integrated Water Resource Management), considering multi-actor articulation and climate resilience.
  • Replication: Developed a comprehensive work model for replication in other medium-sized cities, via knowledge management and south-south cooperation.

The provision of water for Abancay, a growing intermediate city with 72,300 inhabitants, is currently insufficient in dry periods. This problem is generated by two central factors: the decrease in the supply of water in the Mariño micro-basin, the drainage area for the city's water sources, agricultural uses in the micro-basin (28.5 hectares), and population growth 

On the one hand, changes in land use and climate change affect the ecosystem’s ability to regulate water and increase the concentration of sediments, and, therefore less water is available in both quantity and quality. The infrastructure is exposed to greater climate risks, such as landslides and damage to conduit pipes. On the other hand, demand has increased: Abancay has become the third departmental capital with the highest population growth rate at an annual average of 3.5%, after Puerto Maldonado and Ayacucho. That causes inequality and vulnerability: there is an urban population in sectors of the city that can only access water for 4 hours per day. In addition to the above, potable water losses in the supply systems managed by EPS EMUSAP Abancay amount to 41% non-invoiced water.
