The collapse of fisheries, decline of coral reefs and drought are all hitting Madagascar hard. But fishermen are coping with scarce and stressed resources in the Indian Ocean by coming up with new alternatives.
Landing his wooden canoe on the coral-sand coast of Madagascar, just a few steps from his home, fisherman Samba Lahy recalls his childhood: "I started fishing with my parents when I was 18," he told DW. "We used to return home with the pirogue packed with fish."
Today, life in Tampolove - a small village in the south of Madagascar - has changed for Lahy and his family. "Resources are rare," he said. For 1 kilogram (2.2 pounds) of fish per day, fisherman can earn $1 (.87 euros). "On lucky days, a catch goes up to 20 kilograms," Lahy explained.
Fish stocks around the world are being put at risk by climate change, overexploitation, pollution and habitat destruction.
In Madagascar, this is particularly worrying, as fishing contributes more than 7 percent of the national gross domestic product - and is the backbone of the economy in rural areas.
Fish are also the main source of protein for coastal populations.
In the face of looming food insecurity, Madagascar's fishers are getting creative in their quest for alternatives.
Farmers and fishers in trouble
If fisheries continue to decline rapidly, it could have a serious effect in Madagascar, leading to further food shortages and economic problems in one of the poorest countries in Africa.
Compounding this are the effects of climate change, which people are experiencing across the country. Long-lasting drought has led to failing harvests, leaving 850,000 people in a state of severe hunger. As a result, starving families from inland communities have been forced to move to the coast - putting increased pressure on coastal resources.
Add to the equation that coastal communities like Tampolove are experiencing changing weather patterns. "We are well into the rainy season, but have yet to receive rain," said Richard Badouraly, president of the aquaculture community in Tampolove. "Both farmers and fishers are in trouble."
Gildas Todinanahary, of the Institute of Fisheries and Marine Science, University of Toliara, warns that fisheries in Madagascar are further threatened by declining coral reefs.
"Over the past 50 years, 65 percent of the corals of reef off the coast of Toliara have died," he said.
Creating sustainable resources
To prevent ecosystems from collapsing, the Velondriake - an association of several villages all falling within the same marine protected area - was created by the government.
The name means "to live with the sea," and the program is managed by locals. "Fishers understood that they needed to look for alternatives to fishing," said community leader Badouraly.
The marine reserve stretches over 1,000 square kilometers (386 square miles) along the coast of Madagascar, and includes a total population of 7,500 people.
The reserve includes coral reefs, mangroves, seagrass beds, baobab forests and thornscrub. Local community members farm sea cucumbers and seaweed, and conduct monitoring.
Thanks to PACP (Projet d'Appui aux Communautés de Pêcheurs), local people manage much of the project, both governing and establishing alternative activities in the reserves.
Thus, villagers have become both managers and guardians of their own coasts. Management decisions are discussed and agreed upon as a community.
Sea cucumbers, coral and seahorses
In Tampolove, where people's diet consists mainly of fish and rice, fishers have started farming seaweed.
With the support of Blue Ventures, a UK-based marine conservation group, the Wildlife Conservation Society, and the University of Toliara, the village has started to grow seaweed for the European market.
In the last few years, the community has also begun testing the cultivation of sea cucumbers (Holoturia scabra), and of elkhorn sea moss (Kappaphycus alvarezii). Sea moss is a type of red algae, from which carrageenan - a gel used in the food and cosmetic industry - is extracted.
Algae farming is proving a success in the village; production has risen from 13 tons in 2013 to 187 tons in 2016. "And we expect to reach 250 tons this year," Badouraly added.
Family life is also being affected. Women have been financially liberated since becoming the main algae farmers, often working with men, many of whom remain fishers. As a result, the birth rate in the area has decreased.
Next, the community is looking to cash in on sea cucumbers, which have high commercial value. And the fishers are even investigating whether coral and seahorses can also be farmed.
But Todinanahary points out that the real natural riches are in the community. "When we say as scientists, as the government: You should change the way you live - they will give us the solution themselves."
