Nigerians Strive to Bring Mangrove Forests Back to Life

On a riverbank in the Niger Delta, a group of residents in rubber boots has been working to restore one of Nigeria's most precious and damaged ecosystems -- its mangrove forests.
The team members plunge their shovels into the mud and slot in saplings at the site in Bundu, a shanty town on the outskirts of the southern oil city Port Harcourt, AFP said.
In recent years, human activity has destroyed swathes of the world's mangrove forests, which form a vital barrier against the tides and a sanctuary for wildlife.
But in this part of the Delta -- plagued by leaks from multinational oil company pipelines and a host of other threats -- a local community leader is pushing ahead with a project to restore the spoiled forests.
"We're going to bring our mangroves back to life," said fisherman David Oba, 53, who represents around 10,000 people in the town.
'Refuge'
Mangrove forests are a biodiversity paradise. The specialist saltwater trees' huge root networks provide nurseries for juvenile fish, which are crucial to supporting stocks.
The forests teeming with life above water too -- they are "refuges" for an array of birds that nest in their branches, explained Ijeoma Vincent-Akpu, a professor at the University of Port Harcourt.
Vincent-Akpu said the trees also protect against coastal erosion, storms and flooding, providing a key shield in the face of climate change.
Nigeria boasts some of the highest mangrove coverage in the world and more than anywhere else in Africa -- but its forests are shrinking.
The country had around 8,442 square kilometers (3,259 square miles) of mangrove forest in 2020, according to the monitoring platform Global Mangrove Watch.
Between 1996 and 2020 it lost 161.9 square kilometers of mangroves, the group said -- around two percent of the total and an area equal to more than 22,500 football pitches.
Experts say this is mainly due to human activity in the continent's most populous country.
Oil pollution
In Bundu, around 30 people have learned how to restore mangrove ecosystems with the help of a Nigerian NGO, the Centre for Environment, Human Rights and Development.
They have been through several weeks' training, said Nabie Nubari Francis, coordinator of the NGO, which has been running the project in three other communities in the Delta for nearly 15 years.
Priority is given to training community leaders so they can pass on their skills. David Oba said he had trained 70 people in Bundu since starting the project there several months ago.
One of the greatest threats to the mangroves is pollution from the multinational oil industry in the Delta. Residents say whole areas have been wiped out by spills.
Oil spills are frequent in the region due to a lack of pipeline maintenance as well as vandalism. Over the last five years, the National Oil Spill Detection and Response Agency has recorded almost 3,870 spills in Nigeria, mainly in the Niger Delta.
Kwani Dick Velvet, a retired journalist, recalled the first sapling he planted in his community, bought from a nearby nursery.
"If it was not for the fact that people came and planted some mangroves, this place would have been a very open field," he said, pointing to an area that he said was hit by an oil spill in 2020.
Residents said the spill was caused by vandals targeting an oil pipeline.
"When the spillage occurs, we cannot fish," 38-year-old fisherman Peter Opugulaya told AFP.
- Invasive palms -
Oil is not the only problem. Nigeria's mangroves are being damaged by illegal logging, waste dumping and urban expansion.
They face another threat, too -- the spread of Nipa palms, an invasive species that has muscled in among the mangroves.
Imported from South Asia and Oceania, the palms are used for baskets and roofing, but do not provide shelter for fish like the mangroves' arched roots.
Colin Love, from Kono village around 70 kilometers (over 40 miles) from Port Harcourt, complained the palms had taken root "everywhere".
The 40-year-old said he was planting mangroves "so that the fish will still come back for us."
On a visit to the Delta earlier this year, Nigeria's environment minister promised to work with local authorities to protect mangroves and mitigate the effects of climate change.
Four years earlier, the government announced its intention to launch a national mangrove restoration plan, but it was never implemented.
Residents said the government has been slow to act, prompting them to take measures into their own hands.
"We are helping each other," said 48-year-old driver and Kono resident Prince Nwilee, saying that communities were ready to share saplings with their neighbors.
"We are not sitting by and doing nothing," he said.



Japan Crisp Packs to Go Colorless Due to Iran War Crunch

Japan Crisp Packs to Go Colorless Due to Iran War Crunch

Japan's leading potato chip maker is feeling the crunch from shortages linked to the Iran war, swapping its signature orange-and-yellow packets for black and white.

A household name in Japan, Calbee is known for its savory potato chips with an array of flavors from seaweed salt to soy sauce and butter.

The company said Tuesday it will "revise the packaging specifications" and use just "two colors" in packaging for 14 product lines beginning later this month or in June.

It did not say which two colors, but the statement showed photos of grey packaging.

Calbee blamed "supply instability for certain raw materials resulting from the escalating tensions in the Middle East".

Local media said the snack-maker has seen its procurement of printing ink compromised by shortages of naphtha, an oil byproduct used in a wide range of industries.

The goods affected included several potato chip products, as well as a breakfast cereal and Kappa Ebisen, a moreish shrimp snack known for the slogan "can't stop, can't stop".

"We will continue to respond swiftly and flexibly to changes in the business environment, including geopolitical risks, while striving to deliver safe, reliable, and satisfying products," the company said.

Another Japanese food company, Itoham Yonekyu Holdings, also told AFP that going black-and-white or using different kinds of inks for some of its products were among possible options in the future, similarly blaming supply problems due to the Middle East conflict.

Roughly a fifth of the world's oil normally passes through the Strait of Hormuz, and its de facto closure since the war began in late February has sent prices soaring.

Japan's Prime Minister Sanae Takaichi previously said Tokyo was expected to have enough naphtha-derived chemical products to last beyond the end of the year after boosting imports from outside the Middle East.

Last week Takaichi said that the global oil supply squeeze was inflicting an "enormous impact" on the Asia-Pacific region.


What if We Killed all Mosquitoes?

The deadliest animals are not lions, spiders or snakes, but the tiny mosquitoes that suck our blood, make us itchy and infect us with disease.

Mosquitoes kill around 760,000 people every year, according to research site Our World in Data, with humans ourselves coming a distant second.

This is because mosquitoes account for 17 percent of all infectious diseases, including malaria, dengue, yellow fever, chikungunya and Zika.

And as the world warms due to human-driven climate change, mosquitoes are roaming to new areas during longer summers, raising fears they could propel future health crises.

So how can humanity fight back against our greatest foe? Is there a safe way we could eradicate these killer mosquitoes -- and how bad would that be for the environment?

#Notallmosquitoes

First, we would not need to vanquish all mosquitoes. Out of roughly 3,500 mosquito species, only around 100 bite humans.

And just five species are responsible for roughly 95 percent of human infections, Hilary Ranson, a vector biologist at the Liverpool School of Tropical Medicine, told AFP.

On balance, Ranson felt that losing five mosquito species "could be tolerated given the huge devastation" they inflict on the world, from mass death to crippling economic fallout.

Dan Peach, a mosquito entomologist at the University of Georgia, broadly agreed, but emphasized that more information was needed to compare eradication with the alternatives.

What about the environment?

The five disease-spreading mosquitoes "have evolved to be very closely associated to humans," including feeding on and breeding near us, Ranson explained.

This means eradicating them would not have a major impact on the broader ecosystem -- and other, genetically similar but less deadly mosquitoes would likely quickly "fill that ecological niche", she added.

Peach was not convinced we know enough "about the ecology of most mosquito species to be confident one way or the other, but I also think that it is OK to acknowledge this and still proceed."

Mosquitoes do "transfer nutrients from their aquatic larval habitats" to other areas, and serve as food for insects, fish and other animals, he said.

They also pollinate plants, but this "isn't well understood and may vary by species", Peach added.

Ranson acknowledged there is a valid debate over the ethics of humans committing "specicide", while pointing out that we are currently unintentionally wiping out a huge number of species.

How can it be done?

One of the most prominent new technological options is called gene-drive, which involves genetically modifying animals so that they pass down a particular trait to their offspring.

When scientists tweaked females of malaria-carrying Anopheles gambiae mosquitoes to make them infertile, it wiped out a population in the lab over just a few generations.

Target Malaria, funded by the Gates Foundation, has tested this technology in several African countries.

However the effort was dealt a major blow last year when Burkina Faso's military-led government ended testing in the country, where it had been criticized by civil society groups and targeted by disinformation campaigns.

Another strategy involves infecting Aedes aegypti mosquitoes with the bacteria Wolbachia. This can crash their population -- or simply reduce their ability to transmit dengue.

This raises another question: do we actually need to kill them?

What if we made them harmless instead?

When Wolbachia-infected sterile mosquitoes were released in the Brazilian city of Niteroi, there was an 89 percent drop in dengue cases, research showed last year.

More than 16 million people across 15 countries have now been protected by these mosquitoes, with "no negative consequences", Scott O'Neill, founder of the World Mosquito Program, told AFP.

Meanwhile, a project called Transmission Zero is trying to use gene-drive technology to make it so that Anopheles gambiae mosquitoes no longer spread malaria.

Lab research published in Nature late last year suggested the scientists are getting closer to this goal, with the team planning to launch an in-country trial in 2030.

The Burkina Faso setback showed that these projects must have some "political support or buy-in" from the countries where they are tested, study author Dickson Wilson Lwetoijera of Tanzania's Ifakara Health Institute told AFP.

No 'magic bullet'

Rather than just relying on a technological "magic bullet", usually funded by the Gates Foundation, Ranson called for a more "holistic solution" for these diseases.

This would require giving people in disease-hit countries more access to treatment, diagnosis, better housing and better vaccines, she said.

However sweeping foreign aid cuts by Western countries have threatened progress against most mosquito-borne diseases over the last year, humanitarian organisations have warned.

Global Fire Outbreaks Hit Record High as ‘Unprecedented’ Heat Extremes Loom, Scientists Say

Climate change has driven record-breaking outbreaks of fire in Africa, Asia and elsewhere this year, with conditions expected to get worse as the northern hemisphere's summer approaches and El Nino weather patterns kick in, scientists warned on Tuesday.

Fires from January to April have already caused unprecedented levels of damage, burning more than 150 million hectares (370.66 million acres) of land, 20% more than the previous record, according to data compiled by World Weather Attribution, a research group that studies the role played by global warming in extreme weather events.

The researchers said temperature records ‌could be broken this ‌year, causing widespread drought as well as fires, with ‌the impact ⁠of human-induced climate ⁠change compounded by an especially strong "El Nino" effect.

"Whilst in many parts of the world the global fire season has yet to heat up, this rapid start, in combination with the forecast El Nino, means that we're looking at a particularly severe year materializing," said Theodore Keeping, a wildfire expert at Imperial College London and part of the WWA group.

As much as 85 million hectares of land have burned in Africa so far ⁠this year, 23% more than the previous record of ‌69 million hectares, he said.

The unusually high fire ‌activity in Africa is being driven by rapid shifts from extremely wet to extremely dry conditions, he ‌said.

High rainfall produced more grass during the previous growing season, creating an abundance ‌of fuel to feed the drought- and heat-induced savannah fires of the last few months.

EL NINO CONDITIONS DUE THIS MONTH

Asian fires have burned as much as 44 million hectares of land so far this year, nearly 40% more than the previous record year of 2014, ‌with India, Myanmar, Thailand, Laos and China among the worst hit, Keeping said.

He warned that wildfire risks could worsen later ⁠this year, with El ⁠Nino increasing the likelihood of severe heat and drought in Australia, Canada, the United States and the Amazon rainforest.

"The likelihood of harmful extreme fires potentially could be the highest we've seen in recent history if a strong El Nino does develop," he said. El Nino weather conditions, caused by the warming of sea surface temperatures in the Pacific Ocean, are expected to start in May, the World Meteorological Organization said last month.

It could cause droughts in Australia, Indonesia and parts of southern Asia as well as flooding in other regions, and may drive up temperatures, the UN agency warned.

"If there is a strong El Nino later this year, there is a serious risk that the effect of climate change and El Nino ... will result in unprecedented weather extremes," said Friederike Otto, climate scientist at Imperial College London and co-founder of World Weather Attribution.
