India’s wicked problem: how to loosen its grip on coal while not abandoning the millions who depend on it


Anupam Nath/AP

Vigya Sharma, The University of QueenslandIndia is the world’s third largest emitter of greenhouse gases, and its transition to a low-carbon economy is crucial to meeting the goals of the Paris Agreement. But unfortunately, the nation is still clinging firmly to coal.

Our new research considered this problem, drawing on a case study in the Angul district, India’s largest coal reserve in the eastern state of Odisha.

We found three main factors slowing the energy transition: strong political and community support for coal, a lack of alternative economic activities, and deep ties between coal and other industries such as rail.

India must step away from coal, while maintaining economic growth and not leaving millions of people in coal-mining regions worse off. Our research probes this wicked problem in detail and suggests ways forward.

Why India matters

India’s population will soon reach 1.4 billion and this decade it is expected to overtake China as the world’s most populous nation. This, combined with a young population, growing economy and rapid urbanisation, means energy consumption in India has doubled since 2000.

The International Energy Agency (IEA) estimates India will have the largest increase in energy demand of any country between now and 2040.

An affordable, reliable supply of energy is central to raising the nation’s living standards. A recent World Bank analysis found up to 150 million people in India are poor.

Alongside its massive reliance on coal, India has one of the world’s most ambitious renewable energy plans, including an aim to quadruple renewable electricity capacity by 2030.

The IEA says coal accounts for about 70% of India’s electricity generation. And as the nation rebounds from the coronavirus pandemic this year, the rise in coal-fired electricity production is expected to be three times that from cleaner sources.

Coal-powered generation is anticipated to grow annually by 4.6% to 2024, and coal is expected to remain a major emitter of greenhouse gases to 2040.

While India’s energy trajectory remains aligned with its commitments under the Paris Agreement, the speed and readiness of its transition remains a complex, divisive issue. The World Economic Forum’s 2021 Energy Transition Index ranks India 87th out of 115 countries analysed.

Bottlenecks in the transition

Our research involved visits to the Angul district in Odisha in 2018 and 2019, where we conducted focus groups and interviews. Angul is home to 11 coal mines.

We found three crucial bottlenecks to the energy transition, which arguably exist in India’s other coal belts and could derail the nation’s decarbonisation efforts.

First, the Odisha government has historically been very pro-business. Politicians across the spectrum support coal mining and seek to position it as the region’s primary economic lifeline.

The official pro-coal position receives little pushback from Angul residents, who are largely unaware of Odisha’s contribution to national greenhouse gas emissions. Any local opposition to coal usually stems from concern about environmental degradation such as air, water and land pollution.

Most of Angul’s residents felt a deep connection to coal because their livelihood depends on it. One participant told us:

even if all the water is polluted and five inches of dust settles on our well, we would prefer mining to continue as my family’s survival depends on (the contract with the mining company).

Most participants considered their farming land as an asset to be sold to the mining companies for a significant sum. The money would, in turn, allow them to start a business, buy a car or arrange a marriage in the family.

Second, the heavy reliance on coal means efforts to diversify the region’s economy have been grossly neglected.

In Angul, mining zones and coal-dedicated railway lines passing through paddy fields mean agricultural productivity has declined over time. Rural development agendas have been short-lived, often set within six months of an election deadline then changed or abandoned.

Skill-development programs in non-coal vocations have also been limited. This lack of viable alternatives implicitly generates local support for coal.

And third, a suite of industries in Odisha – such as steel, cement, fertiliser and bauxite – depend on cheap coal for power. This is reflected across India, where coal has deep ties with other industries in ways not seen elsewhere.

For example, in 2016 Indian Railways earned 44% of its freight revenue from transporting coal. Indian Railways is India’s largest employer and coal revenue helps keep passenger fares low. So in this way, a potential coal phaseout in India would have far-reaching effects.

The way forward

We offer these pathways to ensure a steady, just energy transition in India:

  • India must help its coal regions diversify their economic activities
  • bipartisan support for a coal-free India is needed. Transition champions such as Germany can show India’s leaders the way
  • a national taskforce for energy transition should be established. It should include representatives from across industry and academia, as well as climate policymakers and grassroots organisations
  • India’s coal regions are endowed with metals needed in the energy transition, including iron ore, bauxite and manganese. With improved regulatory standards, these offer economic alternatives to coal
  • concerns about the coal phase-out from communities in coal regions should be addressed fairly and in a timely way.

The world’s emerging economies are responsible for two-thirds of global greenhouse gas emissions. The energy transition in India, if done well, could show the way for other developing nations.

But as new industrial sectors emerge and clean energy jobs grow, India must ensure those in coal-dependent regions are not left behind.

5 rocks any great Australian rock collection should have, and where to find them


Shutterstock

Emily Finch, Monash UniversityRoad tripping with a geologist is a little different. While you’re probably reading road signs and dodging roadkill, we’re reading road cuttings and deciphering the history of the area over the previous millions — or even billions — of years.

Geology has shaped the Australian landscape. In Victoria where I live, for example, the western plains are pockmarked by Australia’s youngest volcanoes, while the east of the state has been pushed up to form the mountains of the Great Dividing Range.

Along the southern margin of the state are fossilised braided rivers, relics of when Australia drifted away from Antarctica. Evidence of this event extends into Tasmania, where dolerite, a rock that signifies this rift, looms in enormous columns over Hobart from Mount Wellington.

This probably won’t surprise anyone who knows me, but I have rocks peppered around my house that I’ve collected on my travels. Every time I look at them, I not only think about how the rocks were formed, I’m also reminded of the trip when I collected them.

With international and even state borders set to remain closed for a while longer, this is the perfect time to take a great Australian road trip, become a rock detective, and build up your rock collection while you’re at it.

To help you get started, I’ve listed five rocks any great Australian rock collection should have.

1. Mantle xenoliths

Western Victoria

The youngest rocks in Australia are those that erupted out of Australia’s youngest volcano in Mount Gambier, South Australia, 4,000 to 8,000 years ago. That volcano is the culmination of an enormous field of volcanoes that span central and western Victoria.

In western Victoria, the volcanoes were formed from magma that ascended from the Earth’s mantle — the layer between the Earth’s core and crust. While the magma was rising, it tore off chunks of the surrounding mantle rock and transported it to the surface. We can find these chunks of the mantle — or mantle xenoliths (xeno = foreign, lith = rock) — in cooled lava today in western Victoria.

At first, these rocks look like any other piece of black or brown basalt, but then you turn them over or crack them open and there’s a blob of bright green rock staring back at you. The mantle rock inside is comprised mainly of olivine, which is a green mineral, and some black/brown pyroxene.

Mantle xenoliths are a great place to start your rock collection because not only will they be your very own piece of Earth’s mantle, but you can find them yourself through a bit of fossicking around some of the volcanoes in western Victoria.

2. Meteorites

The Nullarbor Desert, South Australia and Western Australia

The Nullarbor is a desert plain region which straddles the border of South Australia and Western Australia.

The dry environment is ideal for preserving meteorites that fall to Earth, and the light colour of the limestone country rock and lack of vegetation means the black and brown meteorites are easier to see.

Even if you don’t have a great eye for spotting meteorites hiding in plain sight, you can do as the geologists do and use a magnet on a stick to help you. Most meteorites are iron-rich, so wandering around with a magnet hovering over the surface is a good way to pick them up.

Thousands of meteorites have been found in the Nullarbor, some up to 40,000 years old.

3. Metamorphic rocks

Broken Hill, New South Wales

You’ve probably heard of Broken Hill because of the large silver, lead and zinc mine there. But the geological conditions that created the ore deposit around 1.7 billion years ago also made some beautiful rocks.

A visit to Broken Hill’s Albert Kersten Mining and Minerals Museum will demonstrate the vast array of unusual minerals found in the region, some of them described for the first time at this locality.

If you’re seeking your own chunk of Broken Hill’s geological history, Round Hill is the place for you. Just a short way out of the town centre, you’ll find beautiful red garnets surrounded by patches of white minerals (quartz and feldspar).

These rocks started out as sand and mud, and record the history of being buried and heated to over 700℃ deep below the Earth’s surface. This process caused the rock to start melting and created the striking stripey, garnet-rich rocks we find there today.

4. Banded iron formation

Western Australia

Banded iron formation is a layered sedimentary rock mainly comprised of alternating bands of chert (a sedimentary rock made of quartz) that’s often red in colour and silver to black iron oxide. It is the main host of iron ore, and can be found in several regions in Western Australia.

The Hamersley Province in the northwestern part of Western Australia has the thickest and most extensive banded iron formations in the world. They are about 2.45 to 2.78 billion years old.

Geologists believe they formed on a continental shelf, where thick continental crust extends out into the ocean and then drops away to oceanic crust.

Banded iron formation is exciting because it no longer forms on Earth today, meaning it records an ancient process that we no longer see happening.

It is thought to have formed in ancient oceans, which were starting to increase in oxygen content at the time. It records the chemical input of these oceans, as well as sediments from the continent and volcanoes on the ocean floor.

5. Dinosaur fossils

Central and western Queensland

Oh to have been in Queensland 100 million years ago! Judging by the fossils found in parts of the state, it would have been a cornucopia of dinosaur activity.

From an unlikely duo of dinosaurs in a 98-million-year-old billabong in Winton, to fossilised evidence of a dinosaur herd at Lark Quarry, Queensland is the place to go to peer back in time to the Mesozoic Era between 252 and 66 million years ago.

And if you’re really lucky, you might even have dinosaur bones on your property, like the huge, long-necked sauropod discovered just this year on a Queensland cattle farm.

When building your Australian rock collection, remember to check first if fossicking is allowed in the area. When you find an interesting rock, your state or territory geological survey might be able to help with identifying it.

Happy hunting!
