Participatory and Climate-Informed Decision Support Systems: Enhancing Water Resource Planning and Climate Action in Peru

Peru is particularly vulnerable to climate change. The increase of temperature, variabilities in precipitation patterns, glacial retreat and intensifying extreme precipitation events threaten the country’s water security. To address these challenges, Peru has prioritized interventions to ensure future water availability for multiple uses such as domestic water supply, agriculture or energy generation, while also managing risks such as floods and droughts. The project supports Peru in achieving long-term climate resilience and low carbon development by implementing ambitious adaptation and mitigation measures in the areas of water, energy and transportation. Innovative management tools will support better decision making and bring together a range of stakeholders from different sectors including governmental institutions, academia, private sector and civil society organizations including women’s right organizations and indigenous populations.

State of implementation/results

  • In the first half of 2025, significant progress was made in the hydrological modelling of the 27 prioritized watersheds:
    • Grouping of the natural hydrological networks into twelve modelling groups
    • Development of new tools within HydroBID-ALLOC to standardize model configurations and facilitate their future use
    • Establishment of quality assurance processes for these tools
  • Between 02/2025 and 04/2025, two rounds of meetings were held with 24 Watershed Councils, Water Administrative Authorities (AAA), Local Water Administrations (ALA), and other stakeholders to present the project and share initial progress in hydrological model configuration.
  • In 05/2025, the first HydroBID-ALLOC workshop was conducted in Lima in a hybrid format, with participation from over 40 professionals from public, private, and academic institutions of the country.
  • The Ministry of Transport and Communications was presented with progress on the implementation of the Blue-Spot Analysis and the participatory selection of criteria to be included in the analysis. The tool aims to identify vulnerable key transportation infrastructure by mapping flood-prone areas within road networks.
  • The initial development of the Decision Support System (DSS), a key component of the project’s climate risk assessment methodology and evaluation of adaptation measures, began in the first half of 2025.
  • Collaboration with the University of Zurich was initiated to plan research studies on glacial retreat, including analyses of economic impacts, water availability, acid rock drainage conditions, future glacier scenarios, and risks related to Glacial Lake Outburst Floods (GLOFs). The university also provides technical input for the integration of a glacier module within HydroBID.
  • In 06/ 2025, development began on a methodology addressing gender and climate change, along with a study on the impacts of glacial retreat on the human rights of mountain communities.
  • The project started developing its stakeholder engagement strategy and communication plan in 06/2025.
  • In 05/2025 and 06/2025, engagement began with the institutions that will form the Group of Thematic Experts on Climate Change and Cross-Cutting Approaches, following the approval of the concept note by the Ministry of Environment.
  • The first consultancy for PROMOVILIDAD in the transport sector is underway in 2025, proposing sustainable urban mobility indicators for integration into the National Urban Transport Policy and identifying interventions to improve urban mobility.
  • The Project Steering Committee was installed in 06/2024, with the participation of eleven representatives from the following organisations: BMWK, IKI Office at ZUG gGmbH, MINAM, SENAMHI, ANA, MINEM, MTC, MVCS, IDB, OAS and RTI.
