Which adaptation strategies are commonly used to manage water resources under climate change?

• A. Do nothing.
• B. Storage, water conservation, groundwater recharge, resilient infrastructure.
• C. Ignore drought forecasts.
• D. Increase irrigation without efficiency.

Answer: (B)

Adapting water resources to climate change centers on making supply more reliable, reducing demand, and ensuring systems can cope with extremes. Storage acts as a buffer, capturing excess during wet periods and releasing water during droughts or dry spells. Conservation lowers overall water use, so existing supplies go further as climate variability intensifies. Groundwater recharge adds an additional, often underground, source of supply that can buffer surface-water variability and reduce reliance on stressed rivers or reservoirs. Building resilient infrastructure means designing and upgrading facilities—dams, canals, treatment plants, and distribution networks—to withstand floods, heat, and other climate-related stresses, keeping service levels intact. Together these strategies address the uncertainties of a changing climate. In contrast, doing nothing, ignoring forecasts, or increasing irrigation without improving efficiency would leave water systems more vulnerable to scarcity and mismanage scarce resources.
