Scientists have concluded that tropical forests demonstrate high resilience, even after they are cut down, due to agriculture or pasture use, if they are left alone for 20 years. According to the study published in December 2021.
“Tropical forests are converted at alarming rates to other land uses yet they also have the potential to regrow naturally on abandoned agricultural fields and pastures. Widespread land abandonment because of fertility loss, migration, or alternative livelihood options has led to a rapid increase in the extent of regrowing forests. Currently, regrowth covers as much as 28% (2.4 million km2) of the neotropics alone. Regrowing secondary forests form a large and important component of human-modified tropical landscapes and have the potential to play a key role in biodiversity conservation, climate change mitigation, and landscape restoration.
Gabon is the first country in Africa to receive results-based payments for reduced emissions from deforestation and forest degradation. The first payment is part of the breakthrough agreement between Gabon and the multi-donor UN-hostedCentral African Forest Initiative’s (CAFI)in 2019 for a total of $150 million over ten years.
At a high-level event organised on Tuesday, Sveinung Rotevatn, Norway’s Minister of Climate and Environment said on behalf of CAFI: “This is the first time an African country has been rewarded for reducing forest-related emissions at the national level. It is extremely important that Gabon has taken this first step. The country has demonstrated that with strong vision, dedication and drive, emissions reductions can be achieved in the Congo Basin forest.” Gabon is leading the way in maintaining its status of High Forest Cover Low Deforestation (HFLD) country. ..
Gabon has preserved much of its pristine rainforest since the early 2000s in creating 13 national parks, one of which is listed UNESCO World Heritage Site. Its forests absorb a total of 140 million tons of CO2 every year, the equivalent of removing 30 million cars from the road globally.
Gabon has also made significant advances in sustainable management of its timber resources outside the parks, with an ambition to ensure that all forest concessions are FSC-certified. Forest spans over 88% of its territory, and deforestation rates have been consistently low (less than 0.08%) since 1990. Gabon’s forests house pristine wildlife and megafauna including 60% of the remaining forest elephants, sometimes called the “architects” or “gardeners” of the forest for their roles in maintaining healthy ecosystems and recently listed as critically endangered.
No ecosystem is more important in mitigating the effects of climate change than tropical rainforest. And South-East Asia is home to the world’s third-biggest patch of it, behind the Amazon and Congo basins. Even though humans release carbon from these forests through logging, clear-felling for agriculture and other disruptions, some are so vast and fecund that the growth of the plants within them absorbs even more from the atmosphere. The Congo basin, for instance, locks up 600m tonnes of carbon a year more than it releases, according to the World Resources Institute (WRI), an international NGO that is equivalent to about a third of emissions from all American transport.
In contrast, such is the extent of clearing for plantations in South-East Asia’s rainforests, which run from Myanmar to Indonesia, that over the past 20 years they have turned from a growing carbon sink to a significant source of emissions—nearly 500m tonnes a year. Indonesia and Malaysia, home to the biggest expanses of pristine forest, have lost more than a third of it this century. Cambodia, Laos and Myanmar, relative newcomers to deforestation, are making up for lost time.
The Global Forest Watch, which uses satellite data to track tree cover, loss of virgin forest in Indonesia and Malaysia has slowed for the fourth year in row—a contrast with other parts of the world…The Leaf Coalition, backed by America, Britain and Norway, along with such corporate giants as Amazon, Airbnb, and Unilever, aims to create an international marketplace in which carbon credits can be sold for deforestation avoided. An initial $1bn has been pledged to reward countries for protecting forests. South-East Asia could be a big beneficiary,
Admittedly, curbing deforestation has been a cherished but elusive goal of climate campaigners for ages. A big un initiative to that end, called REDD+, was launched a decade ago, with Indonesia notably due for help. It never achieved its potential. Projects for conservation must jump through many hoops before approval. The risk is often that a patch of forest here may be preserved at the expense of another patch there. Projects are hard to monitor. The price set for carbon under the scheme, $5 a tonne, has been too low to overcome these hurdles.
The Leaf Initiative would double the price of carbon, making conservation more attractive. Whereas buyers of carbon credits under REDD+ pocketed profits from a rise in carbon prices, windfalls will now go to the country that sold the credits. Standards of monitoring are much improved. Crucially, the scheme will involve bigger units of land than previous efforts, the so-called jurisdictional approach. That reduces the risk of deforestation simply being displaced from a protected patch to an unprotected one.

The Green Climate Fund has promised developing nations it will ramp up efforts to help them tackle climate challenges as they strive to recover from the coronavirus pandemic, approving $879 million in backing for 15 new projects around the world…The Green Climate Fund (GCF) was set up under U.N. climate talks in 2010 to help developing nations tackle global warming, and started allocating money in 2015….
Small island states have criticised the pace and size of GCF assistance…Fiji’s U.N. Ambassador Satyendra Prasad said COVID-19 risked worsening the already high debt burden of small island nations, as tourism dived…The GCF approved in August 2020 three new projects for island nations, including strengthening buildings to withstand hurricanes in Antigua and Barbuda, and installing solar power systems on farmland on Fiji’s Ovalau island.
It also gave the green light to payments rewarding reductions in deforestation in Colombia and Indonesia between 2014 and 2016. But more than 80 green groups opposed such funding. They said deforestation had since spiked and countries should not be rewarded for “paper reductions” in carbon emissions calculated from favourable baselines…. [T]he fund should take a hard look at whether the forest emission reductions it is paying for would be permanent. It should also ensure the funding protects and benefits forest communities and indigenous people…
Other new projects included one for zero-deforestation cocoa production in Ivory Coast, providing rural villages in Senegal and Afghanistan with solar mini-grids, and conserving biodiversity on Indian Ocean islands. The fund said initiatives like these would create jobs and support a green recovery from the coronavirus crisis.

BBC has used satellite data to assess the severity of fires in Brazil, Indonesia, Siberia and Central Africa. It has concluded that although fires in 2019 have wrought significant damage to the environment, they have been worse in the past. More than 35,000 fires have been detected so far in 2019 in East Asia spreading smoky haze to Malaysia, Singapore, the south of Thailand and the Philippines, causing a significant deterioration in air quality. But this is substantially fewer than many other years including those, such as 2015, exacerbated by the El Nino effect which brought unusually dry weather.
In Indonesia, peatland is set alight by corporations and small-scale farmers to clear land for palm oil, pulp and paper plantations, and can spread into protected forested areas. The problem has accelerated in recent years as more land has been cleared for expanding plantations for the lucrative palm oil trade. Old palm trees on plantations that no longer bear fruit are often set on fire to be replaced by younger ones.
The number of recorded fires in Brazil rose significantly in 2019, but there were more in most years in the period 2002 to 2010. There is a similar pattern for other areas of Brazilian forestry that are not part of the Amazon basin. For 2019, we have data up to the end of August, and the overall area burnt for those eight months is 45,000 sq km. This has already surpassed all the area burnt in 2018, but appears unlikely to reach the peaks seen in the previous decade… “Fire signals an end of the deforestation process,” says Dr Michelle Kalamandeen, a tropical ecologist on the Amazon rainforest. “Those large giant rainforest trees that we often associate with the Amazon are chopped down, left to dry and then fire is used as a tool for clearing the land to prepare for pasture, crops or even illegal mining.”
The environmental campaign group Greenpeace has called the fires that have engulfed the Russian region of Siberia this year one of the worst outbreaks this century. The cloud of smoke generated was reported to have been the size of all the European Union countries combined. Forest fires in Siberia are common in the summer, but record-breaking temperatures and strong winds have made the situation particularly bad. Russia’s Federal Forestry Agency says more than 10 million hectares (100,000 sq km) have been affected since the start of 2019, already exceeding the total of 8.6 million for the whole of 2018…. Drawing on data for the number of fires, it is clear that there have been other bad years, notably in 2003.
Nasa satellites have identified thousands of fires in Angola, Zambia and DR Congo.However, these have not reached record levels. “I don’t think there’s any evidence that the fires we’re seeing in Africa are worse than we’ve seen in recent years,” Denis McClean, of the UN Disaster Risk Reduction agency, told the BBC. According to data analysed by Global Forest Watch, fires in DR Congo and Zambia are just above average for the season but have been higher in past years. In Angola, however, fires have been reported at close to record levels this year.
Some have drawn comparisons with the situation in the Amazon, but the fires in sub-Saharan Africa are different. Take DR Congo – most fires are being recorded in settled parts of the country’s southern, drier forest and savannah areas, and so far not in tropical rainforest. Experts say it is difficult to know what is causing these fires, which are seasonal. Many are likely to be on grassland, woodland or savannah in poor farming communities. “Fires are very important landscape management tools and are used to clear land for planting crops,” says Lauren Williams, a specialist in Central and West African forests at the World Resources Institute.

Agriculture continues to present the biggest threat to forests worldwide. Some experts predict that crop production needs to be doubled by 2050 to feed the world at the current pace of population growth and dietary changes toward higher meat and dairy consumption. Scientists generally agree that productivity increase alone is not going to do the trick. Cropland expansion will be needed, most likely at the expense of large swathes of tropical forests – as much as 200 million hectares by some estimates.
Nowhere is this competition for land between forests and agriculture more acute than in Africa. Its deforestation rate has surpassed those of Latin America and Southeast Asia. Sadly, the pace shows no sign of slowing down. Africa’s agriculture sector needs to feed its burgeoning populations- the fastest growing in the world…. What’s more, for the millions of unemployed African youth, a vibrant agriculture sector will deliver jobs and spur structural transformation of the rural economy. Taken together, the pressures on forests are immense. Unless interventions are made urgently, a large portion of Africa’s forests will be lost in the coming decades – one farm plot at a time.
The difficult question is: what interventions can protect forests and support farmers at the same time?
To tackle these complex challenges, the Center for International Forestry Research (CIFOR) has launched a new initiative: The “Governing Multifunctional Landscapes (GML) in Sub-Saharan Africa: Managing Trade-Offs Between Social and Ecological Impacts” Read more

More than 50,000 of the fruit bats are thought to have been killed in Mauritius since 2015, in an attempt to protect fruit in orchards. The bats – also known as flying foxes – are resorting to eating in orchards to survive because only 5 per cent of Mauritius’s native forests remain, animal experts warned. Fruit bats are vital for biodiversity as they pollinate flowers and scatter seeds, enabling trees and plants to grow and spread, according to conservationists. But populations of the flying foxes have fallen by more than 50 per cent in four years, said Vincent Florens, an ecologist at the University of Mauritius. Some believe fewer than 30,000 now remain.
The first cull, in 2015, killed 30,000, and in a second cull, the following year, 7,380 were targeted. The latest cull involved 13,000. Prof Florens said he believed the number killed is much higher than the 50,300 government figure. “The culls took place late in the year, when many mothers were pregnant or had babies,” he told National Geographic. “You shoot one bat and basically kill two.” Others were likely to have been injured and died later, he said.
Scientists are supporting a lawsuit against the government on grounds of animal welfare violations to prevent any more culls…Mahen Seeruttun, Mauritius’s minister of agro-industry and food security, told FDI Spotlight: “We have a large population of bats who will eat fruit crops.

When sub-Saharan Africa comes up in discussions of climate change, it is almost invariably in the context of adapting to the consequences, such as worsening droughts. That makes sense. The region is responsible for just 7.1% of the world’s greenhouse-gas emissions, despite being home to 14% of its people. Most African countries do not emit much carbon dioxide. Yet there are some notable exceptions.
Start with coal-rich South Africa, which belches out more carbon dioxide than Britain, despite having 10m fewer people and an economy one-eighth the size. Like nearly all of its power plants, many of its vehicles depend on coal, which is used to make the country’s petrol (a technique that helped the old apartheid regime cope with sanctions). A petrochemical complex in the town of Secunda owned by Sasol, a big energy and chemicals firm, is one of the world’s largest localised sources of greenhouse gases. Zambia is another exception. It burns so much vegetation that its land-use-related emissions surpass those of Brazil, a notorious—and much larger—deforester.
South Africa and Zambia may be extreme examples, but they are not the region’s only big emitters . Nigerian households and businesses rely on dirty diesel generators for 14GW of power, more than the country’s installed capacity of 10GW. Subsistence farmers from Angola to Kenya use slash-and-burn techniques to fertilise fields with ash and to make charcoal, which nearly 1bn Africans use to cook. This, plus the breakneck growth of extractive industries, explains why African forests are disappearing at a rate of 0.5% a year, faster than in South America. Because trees sequester carbon, cutting them counts as emissions in climate accounting.
Other African countries are following South Africa’s lead and embracing coal…A new coal-fired power plant ….Lamu in Kenya is one of many Chinese-backed coal projects in Africa…Africa’s sunny skies and long, blustery coastlines offer near-limitless solar- and wind-energy potential. But what African economies need now are “spinning reserves”, which can respond quickly to volatile demand, says Josh Agenbroad of the Rocky Mountain Institute, a think-tank in Colorado. Fossil fuels deliver this; renewables do not…. Several countries are intrigued by hybrid plants where most electricity is generated by solar panels, but diesel provides the spinning reserves…
