AMBOASARY SUD, Madagascar: Some days, all Tsimamorekm Aly eats is sugary water. He's happy if there's a handful of rice. But with six young kids and a wife to support, he often goes without.
This is the fourth year that drought has devastated Aly's home in southern Madagascar. Now more than one million people, or two out of five residents, of his Grand Sud region require emergency food aid in what the United Nations is calling a "climate change famine."
"In previous years there was rain, a lot of rain. I grew sweet potatoes and I had a lot of money ... I even got married because I was rich," said Aly, 44.
"Things have changed," he said, standing on an expanse of ochre dirt where the only green to be seen is tall, spiky cacti.
Climate change is battering the Indian Ocean island and several UN agencies have warned in the past few months of a "climate change famine" here.
"The situation in the south of the country is really worrying," said Alice Rahmoun, a spokeswoman with the United Nations' World Food Programme in Madagascar. "I visited several districts ... and heard from families how the changing climate has driven them to hunger."
Rainfall patterns in Madagascar are growing more erratic - they've been below average for nearly six years, said researchers at the University of California at Santa Barbara.
"In some villages, the last proper rain was three years ago, in others, eight years ago or even 10 years ago," said Rahmoun. "Fields are bare, seeds do not sprout and there is no food."
Temperatures in southern Africa are rising at double the global rate, the Intergovernmental Panel on Climate Change says. Cyclones, already more frequent in Madagascar than any other African country, are likely getting stronger as the earth warms, the US government says.
Conflict has been a central cause of famine and hunger in countries such as Ethiopia, South Sudan, Somalia and Yemen, when fighting stopped people moving to find food. But Madagascar is at peace.
"Climate change strongly impacts and strongly accentuates the famine in Madagascar," President Andry Rajoelina said while visiting the worst-affected areas earlier this month. "Madagascar is a victim of climate change."
The country produces less than 0.01 per cent of global carbon dioxide emissions, the World Carbon Project says.
Half a million children are expected to be acutely malnourished in southern Madagascar, 110,000 severely so, the UN Children's Fund says, causing developmental delays, disease and death.
Nutriset, a French company that produces emergency food Plumpy'Nut, opened a plant in southern Madagascar last week. It aims to annually produce 600 tonnes of therapeutic fortified food made of peanuts, sugar and milk for malnourished children.
The Malagasy government is also giving parcels of land to some families fleeing the worst-hit areas. Two hundred families received land with chickens and goats, which are more drought-resilient than cows. They were also encouraged to plant cassava, which is more drought-resilient than maize.
"It's a natural disaster," said Aly. "May God help us."
