Major rivers around the world are changing under the combined pressure of drought, altered rainfall, pollution and the way water is managed, according to a feature by The Guardian.
Rivers supply drinking water, irrigation, fisheries and transport. When their flow or quality changes, the effects reach far beyond their banks.
The feature also looks at efforts to restore rivers. For Nigeria, where the Niger and Benue are central to farming and livelihoods, the questions it raises are directly relevant.
