WATER & RESILIENCE
Water Resilience: The Missing Piece in Many Climate Strategies
Climate change is often experienced through water: too much, too little, at the wrong time or with declining quality. Projects that improve water resilience therefore sit at the intersection of adaptation, infrastructure, agriculture and nature.
Water is a climate transmission channel
Drought affects agriculture, hydropower and urban supply. Floods damage infrastructure and displace communities. Changing rainfall alters groundwater recharge and river flows. Warmer conditions can increase water demand while placing pressure on ecosystems.
This means water should not be treated as a narrow utility issue. It is a system that connects households, farms, industry, energy and nature.
Resilience requires more than building infrastructure
Dams, storage, drainage, irrigation and treatment can be essential, but infrastructure alone is not enough. Projects should consider watershed condition, demand management, maintenance, water governance, climate scenarios and the needs of different users.
Nature can be part of the solution
Wetlands, forests, floodplains and healthy soils influence water storage, filtration and runoff. Nature-based solutions can complement engineered infrastructure by improving watershed function and reducing some climate risks.
Data improves decisions
Water projects benefit from hydrological data, climate projections, metering, remote sensing and local observations. The challenge is turning data into operational decisions: when to allocate water, where to invest, which infrastructure is vulnerable and which users face the greatest risk.
The financing model should reflect the beneficiaries
Some water resilience investments generate direct revenue; others create public benefits that are difficult to monetise. Projects may therefore require a combination of public finance, user fees, development finance, grants or private capital.
It is the ability of the water system and its users to anticipate shocks, absorb them, adapt and continue functioning.
Project opportunities
Promising areas include efficient irrigation, water reuse, leakage reduction, climate-resilient urban drainage, watershed restoration, drought management, flood protection, climate information and distributed water systems.
Across Africa, recent World Bank and African Development Bank initiatives continue to emphasise water security and climate resilience as critical development priorities.
