Residents of the oasis of Alnif say they cannot remember a drought this bad. The land is dry. Some wells are empty. Palm groves that date back more than 100 years are barren.

Home to centuries-old oases that have been a trademark of Morocco, this region, about 274km (170 miles) southeast of Marrakesh, is reeling from the effects of climate change, which have created an emergency for the kingdom’s agriculture.

Among those affected is Hammou Ben Ady, a nomad in the Tinghir region who leads his flock of sheep and goats in search of grazing grass. The drought forced him to rely on government handouts of fodder.

November is usually a cold, wet month in Alnif. But when the rain failed to come, the king called for rain prayers across the country, an old Islamic tradition during desperately dry times.

Resident Mo’chi Ahmad said the oasis has provided a livelihood for this population for hundreds of years. Now it is “threatened with extinction” and everyone has noticed the disappearing palm trees.

In the last three years, hundreds of people from the oasis areas have fled towards cities, many young people migrating to Europe, mainly because of the drought, said Mohamed Bozama, another resident.

He also blames the digging of unauthorised wells and rising demand for water from existing wells for worsening the crisis.

But for Hassan Bouazza, part of the solution lies in the hands of the people of the Alnif region. He was the first to install solar panels on the region’s ksar, or castle, and began relying on the energy produced to dig wells and irrigate his fellow farmers’ lands.
