A new handbook to be published in March 2027

INBO is beginning work on a new handbook on the integration of the water mix into integrated management planning at the basin level, alongside the new handbook on integrated management of sediment transport at basin level. These two manuals follow the one on the transfer of waste and plastics into aquatic environments, released in 2024 during the World Water Forum.

Objectives, Context, and Targets

This handbook explores how integrated water resources management (IWRM) can evolve and expand by incorporating new resources, while preserving its founding principles: a basin-based approach, intersectoral coordination, and inclusive governance. It addresses a growing need for adaptation in the face of water resource pressures by demonstrating how to diversify water sources in a coherent and sustainable manner. The key challenge is to effectively coordinate demand management- by reducing and optimizing the use of blue and green water (surface water and groundwater, respectively) – with the development of alternative resources, particularly non-conventional water sources such as wastewater reuse and desalination. This approach must be integrated into IWRM planning to build resilient water systems while strengthening coordination mechanisms among stakeholders. This handbook is intended for public decision-makers and river basin organizations, providing them with tools to structure, plan, and implement strategies, particularly to ensure secure access to drinking water.

Would you like to submit a case study?

You can share your experience with incorporating the water mix into integrated management planning at the watershed level through a case study. Submissions are welcome in three languages (French, English, Spanish) and should be ½ to 1 page in length, or a maximum of 3,600 characters. A royalty-free illustration or one with permission for use, or graphics (in English or easily translatable) may be included.

Contributions may address the following themes:

Adapting and Strengthening IWRM: advancing integrated water resources management at the basin level by incorporating the water mix: blue water (water flowing in rivers, lakes, and groundwater), green water (water absorbed by soil and plants), and non-conventional water.

Managing water demand: reducing consumption and improving the efficiency of water use across all sectors.

Plan and integrate non-conventional resources: improve planning and regulate the use of alternative solutions (wastewater reuse, desalination) at the basin level.

Create an enabling framework for implementation: adapt institutional, regulatory, and economic frameworks to enable scaling up, finance infrastructure, and ensure resilient, sustainable, and equitable water systems.
