In June, technical staff from the Southern Regional Water Authority (ARA-Sul, IP) and the Northern Regional Water Authority (ARA-Norte, IP) gathered for specialised training sessions focusing on the WE-HARP tool. These sessions, supported by the Blue Deal and facilitated by FutureWater, marked a significant step forward in how water abstraction licenses are currently evaluated in these regions.
Integrating data and modelling
The WE-HARP tool is a custom-built application designed to bridge the gap between administrative data and complex hydrological modelling.
During the training sessions, participants learnt how to use this tool to link the existing Water Resources Information System (SIRHA) with the Water Evaluation and Planning (WEAP) models. They were also shown how this tool can simulate the impact of new water licence requests for agricultural, industrial or domestic use on the water balance of an entire river basin.
Water governance through data-Driven permitting
Adopting WE-HARP enables ARA-Sul and ARA-Norte to transition to a data-driven approach to water management in Southern and Northern Mozambique. This tool enables staff to calculate precise impacts of new abstractions on reservoir levels and existing users, while simulating drought scenarios to protect environmental flows and water supply.
By automating complex processes, this tool allows even non-experts at the two ARAs to carry out in-depth assessments and clearly communicate their decisions to stakeholders.
Securing water for tomorrow
The WE-HARP training in June 2025 marks a significant step towards modernising water licensing by ARA-Sul and ARA Norte. By incorporating the WE-HARP tool into their daily operations, the Water Resources Departments of both ARAs are now better positioned to balance increasing water demands with environmental sustainability, thus ensuring a secure water supply in the future.
