Elephant extinction may raise carbon dioxide levels in atmosphere: Study

Washington D.C., Aug 3: Forest elephants engineer the ecosystem of the entire central African forest, but their catastrophic decline toward extinction has catastrophic implications for carbon policy.

One of the last remaining megaherbivores, forest elephants shape their environment by serving as seed dispersers and forest bulldozers as they eat over a hundred species of fruit, trample bushes, knock over trees and create trails and clearings. Their ecological impact also affects tree populations and carbon levels in the forest, researchers report, with significant implications for climate and conservation policies.

In a paper published in the journal of 'Nature Geoscience,' researchers found that elephant populations in central African forests encourage the growth of slow-growing trees with the high wood density that sequesters more carbon from the atmosphere than fast-growing species which are the preferred foods of elephants.

As forest elephants preferentially browse on the fast-growing species, they cause high levels of damage and mortality to these species compared to the slow-growing, high wood density species. The collapse of forest elephant populations will likely, therefore, causes an increase in the abundance of fast-growing tree species at the expense of slow-growing species, and reduce the ability of the forest to capture carbon.

Stephen Blake, one of the researchers of the study, spent 17 years in central Africa doing, among other things, applied for research and conservation work with elephants. While there, he collected a data set on forest structure and species composition in the Nouabale-Ndoki Forest of northern Congo.

In the current study, Blake's collaborators developed a mathematical computer model to answer the question 'What would happen to the composition of the forest over time with and without elephant browsing?'

To find out, they simulated elephant damage through browsing in the forest and assumed they browse certain plant species at different rates. Elephants prefer fast-growing species in more open spaces. As they feed and browse, they cause damage, knocking off a limb or breaking a shrub. The model calculated feeding and breakage rates along with elephant mortality rates to see their effect on certain woody plants.

"Lo and behold, as we look at numbers of elephants in a forest and we look at the composition of forest over time, we find that the proportion of trees with high-density wood is higher in forests with elephants," Blake said.

"The simulation found that the slow-growing plant species survive better when elephants are present. These species aren't eaten by elephants and, over time, the forest becomes dominated by these slow-growing species. Wood (lignin) has a carbon backbone, meaning it has a large number of carbon molecules in it. Slow growing high wood density species contain more carbon molecules per unit volume than fast-growing low wood density species. As the elephants "thin" the forest, they increase the number of slow-growing trees and the forest is capable of storing more carbon."

These findings suggested far-ranging ecological consequences of past and present extinction. The loss of elephants will seriously reduce the ability of the remaining forest to sequester carbon. Trees and plants use carbon dioxide during photosynthesis, removing it from the atmosphere. For this reason, plants are helpful in combating global warming and serve to store carbon emissions.

Without the forest elephants, less carbon dioxide will be taken out of the atmosphere. In monetary terms, forest elephants represent a carbon storage service of $43 billion.

"The sad reality is that humanity is doing its best to rid the planet of elephants as quickly as it can. Forest elephants are rapidly declining and facing extinction. From a climate perspective, all of their positive effect on carbon and their myriad other ecological roles as forest gardeners and engineers will be lost," Blake concluded.

The ILO has warned that if another Covid-19 wave hits in the second half of 2020, there would be global working-hour loss of 11.9 percent - equivalent to the loss of 340 million full-time jobs.

According to the 5th edition of International Labour Organisation (ILO) Monitor: Covid-19 and the world of work, the recovery in the global labour market for the rest of the year will be uncertain and incomplete.

The report said that there was a 14 percent drop in global working hours during the second quarter of 2020, equivalent to the loss of 400 million full-time jobs.

The number of working hours lost across the world in the first half of 2020 was significantly worse than previously estimated. The highly uncertain recovery in the second half of the year will not be enough to go back to pre-pandemic levels even in the best scenario, the agency warned.

The baseline model – which assumes a rebound in economic activity in line with existing forecasts, the lifting of workplace restrictions and a recovery in consumption and investment – projects a decrease in working hours of 4.9 percent (equivalent to 140 million full-time jobs) compared to last quarter of 2019.

It says that in the pessimistic scenario, the situation in the second half of 2020 would remain almost as challenging as in the second quarter.

“Even if one assumes better-tailored policy responses – thanks to the lessons learned throughout the first half of the year – there would still be a global working-hour loss of 11.9 per cent at the end of 2020, or 340 million full-time jobs, relative to the fourth quarter of 2019,” it said.

The pessimistic scenario assumes a second pandemic wave and the return of restrictions that would significantly slow recovery. The optimistic scenario assumes that workers’ activities resume quickly, significantly boosting aggregate demand and job creation. With this exceptionally fast recovery, the global loss of working hours would fall to 1.2 per cent (34 million full-time jobs).

The agency said that under the three possible scenarios for recovery in the next six months, “none” sees the global job situation in better shape than it was before lockdown measures began.

“This is why we talk of an uncertain but incomplete recovery even in the best of scenarios for the second half of this year. So there is not going to be a simple or quick recovery,” ILO Director-General Guy Ryder said.

The new figures reflect the worsening situation in many regions over the past weeks, especially in developing economies. Regionally, working time losses for the second quarter were: Americas (18.3 percent), Europe and Central Asia (13.9 percent), Asia and the Pacific (13.5 percent), Arab States (13.2 percent), and Africa (12.1 percent).

The vast majority of the world’s workers (93 per cent) continue to live in countries with some sort of workplace closures, with the Americas experiencing the greatest restrictions.

During the first quarter of the year, an estimated 5.4 percent of global working hours (equivalent to 155 million full-time jobs) were lost relative to the fourth quarter of 2019. Working- hour losses for the second quarter of 2020 relative to the last quarter of 2019 are estimated to reach 14 per cent worldwide (equivalent to 400 million full-time jobs), with the largest reduction (18.3 per cent) occurring in the Americas.

The ILO Monitor also found that women workers have been disproportionately affected by the pandemic, creating a risk that some of the modest progress on gender equality made in recent decades will be lost, and that work-related gender inequality will be exacerbated.

The severe impact of Covid-19 on women workers relates to their over-representation in some of the economic sectors worst affected by the crisis, such as accommodation, food, sales and manufacturing.

Globally, almost 510 million or 40 percent of all employed women work in the four most affected sectors, compared to 36.6 percent of men, it said.

The report said that women also dominate in the domestic work and health and social care work sectors, where they are at greater risk of losing their income and of infection and transmission and are also less likely to have social protection.

The pre-pandemic unequal distribution of unpaid care work has also worsened during the crisis, exacerbated by the closure of schools and care services.

Even as countries have adopted policy measures with unprecedented speed and scope, the ILO Monitor highlights some key challenges ahead, including finding the right balance and sequencing of health, economic and social and policy interventions to produce optimal sustainable labour market outcomes; implementing and sustaining policy interventions at the necessary scale when resources are likely to be increasingly constrained and protecting and promoting the conditions of vulnerable, disadvantaged and hard-hit groups to make labour markets fairer and more equitable.

“The decisions we adopt now will echo in the years to come and beyond 2030. Although countries are at different stages of the pandemic and a lot has been done, we need to redouble our efforts if we want to come out of this crisis in a better shape than when it started,” Ryder said.

May 28: Abdul Kareem was forced out of school and into a life of odd jobs like repairing bicycles before he finally managed to pull his family out of abject poverty transporting goods across Delhi in a mini truck.

The job, and the slim financial security that came with it, was the first stepping stone to a better life.

All that is now gone as India reels under the economic impact of its protracted coronavirus lockdown. Mr Kareem's out of a job and stranded in his village in Uttar Pradesh with his wife and two children. Their minuscule savings from his Rs 9,000 a month job have been exhausted, and the money he saved for books and school uniforms is spent.

"I don't know what the job situation will be in Delhi once we go back," Mr Kareem said. "We can't stay hungry so I will do whatever I find."

At least 49 million people across the world are expected to plunge into "extreme poverty" -- those living on less than $1.90 per day -- as a direct result of the pandemic's economic destruction and India leads that projection, with the World Bank estimating some 12 million of its citizens will be pushed to the very margins this year.

Some 122 million Indians were forced out of jobs last month alone, according to estimates from the Center for Monitoring Indian Economy, a private sector think tank. Daily wage workers and those employed by small businesses have taken the worst hit. These include hawkers, roadside vendors, workers employed in the construction industry and many who eke out a living by pushing handcarts and rickshaws.

For Prime Minister Narendra Modi, who came to power in 2014 promising to lift the poorest citizens out of poverty, the fallout from the lockdown brings with it significant political risk. He won an even larger second term majority last year on the strength of his government's popular social programs that directly targeted the poor, such as the provision of cooking gas cylinders, power and public housing. The breadth and depth of this renewed economic pain will only increase the pressure on his government as it works to steer the country's economy back on track.

"Much of the Indian government's efforts to mitigate poverty over the years could be negated in a matter of just a few months," said Ashwajit Singh, managing director of IPE Global, a development sector consultancy that advises several multinational aid agencies. Noting that he did not expect unemployment rates to improve this year, Singh said: "More people could die from hunger than the virus."

Desperate Times

Mr Singh points to a United Nations University study estimating 104 million Indians could fall below the World Bank-determined poverty line of $3.2 a day for lower-middle-income countries. This will take the proportion of people living in poverty from 60% -- or 812 million currently, to 68% or 920 million -- a situation last seen in the country more than a decade ago, he said.

A World Bank report found the country had been making significant progress and was close to losing its status as the country with the most poor citizens. The impact of PM Modi's lockdown risks reversing those gains.

The World Bank and the CMIE estimates were published in late April and early May respectively. Since then the situation has only become grimmer, with harrowing images of people making desperate attempts to reach their villages, on crowded buses, the flatbeds of trucks and even on foot or on bicycles dominating media coverage.

The Rustandy Center for Social Sector Innovation at the University of Chicago Booth School of Business analyzed the unemployment data from the CMIE, collected through surveys covering about 5,800 homes across 27 states in April.

Researchers found rural areas were the hardest hit, and the economic misery was the result of the lockdown, rather than the spread of infections in the hinterland. More than 80% of households had experienced a drop income and many won't survive much longer without aid, they wrote in a report.

The government has promised cheap credit to farmers, direct transfer of money to the poor and eased access to food security programs -- but these help people who have some documentation, which many of the poorest don't. With millions of impoverished people now in transit across the country, the food security situation is dire -- news reports are emerging of people foraging through piles of rotting fruit or eating leaves.

Shattered Economy

The economy was already growing at its slowest pace in over a decade when the virus struck. The lockdown, which came into effect on March 25, has hammered it, stalling business activity and putting a lid on consumption, pushing the economy to what may be its first full-year contraction in more than four decades.

It's dire enough to warrant the country exiting its lockdown, as it has been doing incrementally since May 4, even as its infections are surging. India is now Asia's virus hotspot with infections crossing 151,000 according to data from Johns Hopkins University.

PM Modi, who has come under criticism for the pain inflicted on the poor, has said his government will spend $265 billion or about 10% of its GDP to help Asia's third-largest economy weather the pandemic's fallout. But experts say only a part of it is direct fiscal stimulus, and probably smaller than the total damage done to the economy during the lockdown period.

"What is especially worrying is the government's response," said Reetika Khera, an economics professor at the Indian Institute of Technology in Delhi. "The epidemic will magnify existing -- and already high -- inequalities in India."

Still, the economic measures aren't going to kick in for some time and industry will likely struggle to restart because of the flight of labour from industrial hubs.

And as the harsh summer unfolds more pain lies in store in the villages now dealing with returning migrant workers.

"There are no factories or industries here, there are just hills," said Surendra Hadia Damor, who had walked nearly 100 km from Ahmedabad, Gujarat, before a voluntary organisation drove him to his village in the neighboring state of Rajasthan. "We can survive for a month or two and then try and find a job nearby -- we will see what happens."
