Chad hopes 'green charcoal' can save vanishing forests
N'DJAMENA - As they zigzagged from one machine to another in the searing African sun, the workers were covered in black soot.
But the charcoal they were making is known as "green", and backers hope it can save impoverished Chad from rampant deforestation.
Chad, a vast, landlocked country of 19 million people perched at the crossroads of north and central Africa, is steadily turning to desert.
It has lost more than 90 percent of its forest cover since the 1970s, hit by climate change and overexploitation of trees for household uses such as cooking, officials say.
"Green charcoal" aims to protect what forest is left.
Made from discarded plant waste such as millet and sesame stalks or palm fronds, it is meant to save trees from being chopped down for cooking.
The product "releases less emissions than traditional charcoal, it doesn't blacken your pots, it has high energy content and lasts up to three times longer than ordinary charcoal," said Ousmane Alhadj Oumarou, technical director of the Raikina Association for Socioeconomic Development (Adser).
"Using one kilogram of green charcoal saves six kilograms of wood."
The group has installed a production facility in Pont Belile, just north of the capital, N'Djamena.
There, workers grind up burnt plant waste, then mix it with gum arabic, which helps it ignite, and clay, which makes it burn more slowly.
The resulting black nuggets look like ordinary charcoal.
Like the traditional kind, it emits CO2 when it burns -- but less, said Souleymane Adam Adey, an ecologist at the University of N'Djamena.
And "it contributes to fighting deforestation, by ensuring the trees that aren't cut down continue to capture and store carbon," he said.
- Refugee pressure -
The conflict in neighbouring Sudan, which is facing one of the worst humanitarian crises in the world, is adding to pressure on Chad, which has become home to more than 800,000 Sudanese refugees since 2023 -- double the 400,000 it already hosted.

"Desertification has progressed in the regions that have been hosting Sudanese refugees for the past two years," said Adser's director, 45-year-old businessman Ismael Hamid.
Adser invested 200 million CFA francs (about $350,000) to launch the project, then won backing from the World Bank, which buys the charcoal for 750 CFA francs per kilogramme.
The United Nations refugee agency, UNHCR, distributes the charcoal in refugee camps in eastern Chad.
But Hamid said he hoped to expand production and slash prices to 350 to 500 CFA francs per kilo to make "green charcoal" available and affordable nationwide.

The plant currently produces seven to nine tonnes per day.
"If we want to meet the country's needs, we have to increase our output by at least a factor of 10," said Hamid, calling for subsidies to support the budding sector.
Environment Minister Hassan Bakhit Djamous told AFP the government was working on a policy to promote such projects.
"We need to bet on green charcoal as an energy source for the future of our country," he said.

Suriname's battle to keep sea at bay
PARAMARIBO - In the dead of night on a beach in Suriname's capital Paramaribo, a group of just-hatched baby sea turtles clamber out of their sandy nesting hole and race, flippers flailing, towards the sea. For years, endangered leatherbacks and green turtles have emerged onto Braamspunt beach to lay their eggs. But the land spit at the tip of the Suriname river estuary is rapidly vanishing as erosion, caused by rising sea levels linked to climate change, gobbles up entire swathes of Paramaribo's coastline. "Maybe we'll get one more season out of this," Kiran Soekhoe Balrampersad, a guide who accompanied a group of tourists on a recent expedition to see the nesting turtles, told AFP. "But after that there'll no longer be a beach," he added dolefully. Suriname, South America's smallest country, is one of the most vulnerable in the world to rising sea levels. Nearly seven out of ten people in the former Dutch colony of 600,000 inhabitants live in low-lying coastal areas, according to the UN Intergovernmental Panel on Climate Change. AFP | Juan BARRETO "Every day I see a piece of my land disappear," said Gandat Sheinderpesad, a 56-year-old farmer who has lost 95 percent of his smallholding to the sea. Local authorities have for years been trying to find a way to hold back the tide. "Some areas are not problematic because we have 5, 10, even 20 kilometres of mangrove" acting as a buffer between the waves and the shore, Minister of Public Works Riad Nurmohamed told AFP. But near Paramaribo, "there is just one kilometre so it's a very vulnerable zone," he added. In 2020, a program to restore the capital's mangroves was launched. UN Secretary General Antonio Guterres sought to add VIP power to the initiative in 2022 by wading into the mud to personally plant seedlings. But five years later, Sienwnath Naqal, the climate change and water management expert who led the project, surveys a scene of desolation. The sea is now lapping at the edge of a road and the wooden stakes to which he had attached hundreds of samplings are largely bare. AFP | Juan BARRETO High seas carried away the substrate sediment, leaving the roots exposed. "Over the last two to three years the water forcefully penetrated the mangroves, which were destroyed," Nurmohamed said. The dredging of sand at the entrance to Paramaribo estuary to facilitate the passage of boats headed upriver to the port also contributed to the erosion, said Naqal. But like the Amazon rainforest in neighbouring Brazil, the destruction was also deliberate in places, with farmers uprooting mangroves to make way for crops. - 'No time to waste' - With the water lapping at the feet of Paramaribo's 240,000 people, Suriname has changed tack and set about building a dyke. For Sheinderpesad, the levee represents his last chance of remaining on his land. "I have nowhere else to go. When we have the dyke, I will be safer, although I'm not sure for how long," he said. The 4.5 kilometre-long barrier will cost $11-million, which the government has vowed to fund from state coffers. AFP | Juan BARRETO "If you go see donors it takes years before you can start to built. We have no time to waste, we'll be flooded," Nurmohamed explained. But plugging one hole in the country's maritime defenses will not suffice to keep the mighty Atlantic at bay. The government wants to build up the entire network of dykes that dot the country's 380-kilometer coastline. It's just not sure where to find the money. "It's a colossal investment," Nurmohamed said. The country's newly discovered offshore oil deposits may provide the answer. Last year, French group TotalEnergies announced a $10.5 billion project to exploit an oil field off Suriname's coast with an estimated capacity of producing 220,000 barrels per day. by Anne-sophie Thill

Sudan refugees face deepening hunger as funds dry up: UN
KHARTOUM - Millions of people displaced by the war in Sudan are at risk of falling deeper into crisis as funding for food aid dwindles, the UN's World Food Programme warned Monday. Since April 2023, war between the Sudanese army and paramilitary Rapid Support Forces has created the world's largest displacement crisis, with more than 10 million people displaced inside the country. Another four million have fled across borders, mainly to Chad, Egypt and South Sudan. "This is a full-blown regional crisis that's playing out in countries that already have extreme levels of food insecurity and high levels of conflict," said Shaun Hughes, WFP's emergency coordinator for the Sudan regional crisis. The United Nations says its humanitarian response plan for Sudan – also the world's largest hunger crisis – is only 14.4 percent funded. A UN conference in Spain this week aims to rally international donors, following deep funding shortfalls that have affected relief operations globally. The WFP warned support to Sudanese refugees in Egypt, Ethiopia, Libya and the Central African Republic "may grind to a halt in the coming months as resources run dry". In Egypt, which hosts around 1.5 million people who fled Sudan, food aid for 85,000 refugees - 36 percent of those previously supported - had already been cut. Without new funding, the WFP warned, all assistance to the most vulnerable refugees would be suspended by August. In Chad, where more than 850,000 people have fled but find little help in overwhelmed camps, the WFP said food rations would be reduced even further. Around 1,000 refugees continue to arrive in Chad each day from Sudan's western Darfur region, where famine has already been declared and displacement camps regularly come under attack. "Refugees from Sudan are fleeing for their lives and yet are being met with more hunger, despair, and limited resources on the other side of the border," said Hughes. "Food assistance is a lifeline for vulnerable refugee families with nowhere else to turn." Inside Sudan, more than eight million people are estimated to be on the brink of famine, with nearly 25 million suffering dire food insecurity.

Warm up the kitchen with indoor plants
Plants bring life and colour into the kitchen, just as they do in any other room. Plants also create a companionable ambiance and there are many plants that improve air quality as well. Bright and light kitchens are good for plants too. They are warm and humid which suits most indoor plants that originate from tropical forests. Best indoor plants for kitchens Because kitchens are workspaces, compact, slow growing plants that don't take up much space are the most suitable. These include peperomia, peace lily, flowering pot plants like kalanchoe, African violets, chrysanthemums, and anthurium, succulents such as Haworthia, echeveria, and cacti and trailing plants like Philodendron scandens and Golden Pothos (Scindapsus aureus.) Maiden hair fern and Bird's nest fern (Asplenium) as well as Sansevieria and even bamboo palms (Areca) enjoy the warmth and humidity of a kitchen. Care for kitchen plants Keep an eye on plants for fat splatters which attract dust to the leaves. Once a layer of dust settles it smothers the air pores and leaves aren't able to photosynthesise. Make it a regular weekly task to wipe the leaves with a moist piece of cotton wool or cloth. African violets are particularly susceptible to dust on their leaves. Clean by wiping gently with a damp cloth or microfibre cloth or brush the leaves with a soft toothbrush brush. Plants that like warmth and humidity should be closer to the stove and can trail from the top of the fridge. Air purifying plants Quite a number of indoor plants have air purifying qualities and are compact enough for a kitchen where space is an issue. Mother-in-laws tongue (Sansevieria) absorbs carbon and increases the levels of oxygen. Sansevieria grows in medium to bright light and should dry out moderately before watering.. Peace lily (Spathiphyllum) filters unpleasant odours tolerates low light and needs minimal water. Bird's nest fern (Asplenium antiquum) absorbs carbon and increases oxygen levels. Plants like a warm room and moist soil. Misting the leaves improves humidity. Calathea purifies the air, likes warm rooms and low to medium light. Keep soil slightly moist. Flowering plants for countertops and windowsills Kalanchoe and calandiva are succulents that need very little care, good light and moist but not wet soil. They are indoor stalwarts with long lasting flowers Cut off the dead flower spikes, feed with a liquid fertiliser, and they will come into flower again. Also try: Succulents such as echeveria, cactus and Haworthia (Zebra plant) that are ideal for sunny kitchens. They will thrive on a windowsill, and need very little water, yet always look decorative. Anthuriums, especially the mini's, are long-lasting plants that survive neglect. They like bright indirect light. Wipe the leaves to remove dust. Pot Begonias are rewarding indoor plants with their bold, beautiful blooms. Keep in a warm room, with bright indirect light and don't over water. Chrysanthemums like bright light and moist soil. Can be planted into the garden in summer. African violets like bright indirect light and humidity and should only be watered with the soil is slightly dry to the touch. Trailing plants for hanging baskets Golden Pothos (Scindapsus aureus) has variegated yellow and green leaves. Keep plants compact with regular trimming. It tolerates low light, and the soil can dry out before watering again. Philodendron scandens, also known as the sweetheart plant for its heart-shaped leaves is a vigorous grower, easily trained as an indoor climber or for trailing down from shelves.
