Growing up in a village in Burkina Faso, Georges Bazongo remembers his parents and neighbors cutting down trees each year to expand their farmland so they could “grow enough food for our families.”
He also noticed some trees becoming drier in the drought-prone region, an indication that the soil was deteriorating as heavy rains washed away its fertile layer.
Some of his relatives moved to Ivory Coast in search of a better life, 48-year-old Bazongo said.
Things started improving a decade ago when the government and environmental groups helped villagers understand the risks of their degraded land, said Bazongo, director of operations at Tree Aid.
About a quarter of the planet’s land area is in a bad condition due to natural processes such as erosion, and human practices like deforestation and overgrazing, scientists say.
At Bazongo’s village, more than 160km from the capital Ouagadougou, local people have identified forest areas where tree-cutting is forbidden, developed soil and water conservation methods, and diversified crops, he said.
Now, even though his family there has swelled from 16 members to 36 and climate shocks continue, they get enough food from agriculture, livestock and forest produce — and no longer need to expand their farmland, he added.
The village is part of the Great Green Wall initiative, a regional program that seeks to rein in climate-change impacts, cut hunger, create jobs and reduce conflict by restoring a belt of land below the Sahara.
“We’re lucky to learn these new skills,” said Bazongo, whose charity supports the initiative in five countries.
“But what about the other millions of families living in poverty? That means they still continue to expand [farm] land, cut trees, and destroy plant and animal habitats because they can’t see any alternatives,” he said.
Getting funding has been a challenge, he said, adding he was “very happy” to hear France’s announcement on Monday that development banks and governments had pledged US$14.3 billion for work on the Great Green Wall.
At the One Planet Summit in Paris, French President Emmanuel Macron hailed donors for beating a US$10 billion target and said France would ensure commitments were kept.
“We are now standing shoulder to shoulder with ... the entire African continent,” he said.
SEEKING CHANGE: A hospital worker said she did not vote in previous elections, but ‘now I can see that maybe my vote can change the system and the country’ Voting closed yesterday across the Solomon Islands in the south Pacific nation’s first general election since the government switched diplomatic allegiance from Taiwan to Beijing and struck a secret security pact that has raised fears of the Chinese navy gaining a foothold in the region. The Solomon Islands’ closer relationship with China and a troubled domestic economy weighed on voters’ minds as they cast their ballots. As many as 420,000 registered voters had their say across 50 national seats. For the first time, the national vote also coincided with elections for eight of the 10 local governments. Esther Maeluma cast her vote in the
Nearly half of China’s major cities are suffering “moderate to severe” levels of subsidence, putting millions of people at risk of flooding, especially as sea levels rise, according to a study of nationwide satellite data released yesterday. The authors of the paper, published by the journal Science, found that 45 percent of China’s urban land was sinking faster than 3mm per year, with 16 percent at more than 10mm per year, driven not only by declining water tables, but also the sheer weight of the built environment. With China’s urban population already in excess of 900 million people, “even a small portion
UNSETTLING IMAGES: The scene took place in front of TV crews covering the Trump trial, with a CNN anchor calling it an ‘emotional and unbelievably disturbing moment’ A man who doused himself in an accelerant and set himself on fire outside the courthouse where former US president Donald Trump is on trial has died, police said yesterday. The New York City Police Department (NYPD) said the man was declared dead by staff at an area hospital.

A large number of police officers were nearby when it happened. Some officers and bystanders rushed
HYPOCRISY? The Chinese Ministry of Foreign Affairs yesterday asked whether Biden was talking about China or the US when he used the word ‘xenophobic’ US President Joe Biden on Wednesday called for a hike in steel tariffs on China, accusing Beijing of cheating as he spoke at a campaign event in Pennsylvania. Biden accused China of xenophobia, too, in a speech to union members in Pittsburgh. “They’re not competing, they’re cheating. They’re cheating and we’ve seen the damage here in America,” Biden said. Chinese steel companies “don’t need to worry about making a profit because the Chinese government is subsidizing them so heavily,” he said. Biden said he had called for the US Trade Representative to triple the tariff rates for Chinese steel and aluminum if Beijing was
