Water

Water security, treatment and desalination

Large storage tanks beside a wide river and wooded hills

Overview

Securing, treating and reusing water as rainfall patterns shift and demand from cities, farms and industry grows.

Challenges01

What makes change hard

  • Shifting rainfall that brings both droughts and floods.

  • Treating and pumping water takes a great deal of energy.

  • Cities, farms and industry drawing on the same sources.

Opportunities02

Where change is happening

  • Reusing treated wastewater.

  • Restoring wetlands and catchments that store and clean water naturally.

  • Monitoring and leak detection that cut losses from networks.

Solutions

Approaches in this system.

  1. 01

    Treated wastewater reuse

    Cleaning wastewater to a standard where it can be used again, for farms, industry or rivers.

Connections

Energy

Power plants need water for cooling, and pumping and treating water needs energy.

Quick answers about the platform and its content.

One of eight broad areas, such as energy, buildings or water, where climate change is felt and addressed. Solutions and projects are organised around them.

They cover the main sources of emissions and the main places adaptation happens, while staying few enough to hold in mind at once.

Only well-established mechanisms are included, described in words. No quantities are attached unless a source supports them.

Yes, constantly. That is the point of mapping them together: a change in one shifts what is possible in others.

From published research and practice. Every entry is reviewed by people who know the field and linked to the systems, solutions and projects it relates to.
