How can we ensure that we build water and climate resilient cities?

As population and economic growth bump up against finite—and increasingly degraded—water resources, competition between agricultural, industrial, and municipal water uses increases, putting stress on existing water sources. This stress is felt most acutely in urban areas, particularly among the urban poor.
Moreover, urban water management systems are inefficient, leading to an uneven quantity and availability of water and related services. In addition, urban water management must consider the effects of climate change, including rising temperatures, changes in precipitation patterns, and climate variability, on water resource availability.

Addressing these challenges requires building resilience not only in cities’ physical infrastructures but also in their social architecture, governance structures, financial systems, and ecosystems. A resilient city can adapt to changing conditions and withstand shocks while still providing essential services.

What Does Water Look Like in a 4-Degrees World?

Turn Down the Heat report

All climate negotiations have been based on staying below 2°C above pre-industrial temperatures. Yet it looks increasingly unlikely that that will be possible. A new report, Turn Down the Heat: Why a 4°C Warmer World Must be Avoided, suggests that there is a 40 percent chance that we will reach 4°C by 2100 even if we stick to the agreed emission reduction commitments.

What does water look like in a 4°C world?

Put simply: it's complex. Water is a complicated system and one of the major impacts of climate change is the effect on the hydrological (water) cycle.  These impacts will coincide with an unprecedented increase in demand for water because of population and economic growth.
