Small-scale water solutions are a key to increasing agricultural productivity in the face of climate change, says water expert David Molden.

The current way of assessing water scarcity in Africa should be abandoned in favour of one designed for local realities, argues Richard Taylor.

Coping with climate change requires a greater understanding of the options for water storage, writes hydrology expert Matthew McCartney.

Policymakers must find flexible plans to ensure water security despite the uncertainties of climate change, says climate scientist Mark New.

Innovative agricultural technologies can produce crops that meet climate change challenges, says ICRISAT head William Dar.

Kenyan MP and remote sensing expert, Wilbur Ottichilo, argues the time is ripe for using satellites to spot developing African droughts.

Water shortages do not, and will not, cause wars — cooperation is the dominant response to shared water resources, says Wendy Barnaby.

Anti-drought technologies aren't enough to solve China's water shortages — better agricultural water management is essential, says Li Taige.

We must learn to live with less water by investing in infrastructure and knowledge to help maximise what we have, says David Molden.

Super crops won't be enough — the planet will run short of food by 2030 unless we invest to avoid an imminent world water crisis, says Colin Chartres.
