Background
In September, a study published in the journal Science said earth may have already passed through five dangerous tipping points due to the 1.1°C of global heating caused by humanity to date.
Calls for developing and transferring technologies to support action on climate change have become louder worldwide. Technology has become a survival strategy for our species, but the degree of techno-determinism that exists in the strategy to reverse climate change is alarming. Technology alone is unprepared to deal with the challenge, which requires a societal overhaul and a zero-emission strategy.
History is on the side of technological innovation. Norman Borlaug, for instance, ushered in the Green Revolution, which fed billions of people and increased yields. But we may need a few million climate Borlaugs to tackle the problems staring at us.
Technological optimism
COP26 at Glasgow also fuelled technological optimism. There was an observation that every technological solution discussed at COP26 depends on just three resources: nelectricity (non-emitting electricity generated by hydropower, renewables or nuclear fission), carbon capture and storage (CCS) or biomass. The total demand for those resources required by the plans discussed at COP26 cannot be met by 2050.
We currently have 4kWh/day of nelectricity per person. But the COP26 plans require 32 (range 16-48).
We currently have 6kg of CCS per person per year, but the COP26 plans require 3,600 (range 1,400-5,700).
We eat 100kg plant-based food per person each year, but producing enough bio-kerosene to fly at today’s levels requires 200kg of additional harvest. There is no possibility that our supplies of these will be near the levels required by the plans discussed at COP26.
In 2003, Ken Caldeira at the Carnegie Institution found that the world would need a nuclear plant’s worth of clean-energy capacity every day between 2000 and 2050 to avoid catastrophic climate change. In 2018, MIT Technology Review reported that at the given rate, the world will take nearly 400 years to transform the energy system.
Tech-centric mitigation conversations leave forest economies and subjects such as conservation and forests, which are the best carbon removal instruments, to the ideological fringes of climate conversation. Climate action requires the same amount of investment in conservation as we see in shiny new technology transfers.
While there was the deforestation-ending climate commitment at COP26, the nature of the pledge was vague. Countries may easily attempt to achieve their ‘net zero deforestation goals’ through monoculture farming. But this won’t be of much help: scientists, in a commentary in Nature, have stated that naturally preserved forests are 40% more effective than planted ones.
Our climate crisis is intertwined with other complex issues. This means that we must insist on multi-pronged, interconnected climate solutions.
Forests shine here too. Nothing exemplifies this more than the intersection of the climate change crisis and the biodiversity crisis. Forests, which are home to 80% of terrestrial wildlife, are at this intersection.
Forests absorb a net 7.6 billion metric tonnes of CO2 a year. A new study has found that their biophysical aspects have a tendency to cool the earth by an additional 0.5%.
The conservation of forests, along with other nature-based solutions, can provide up to 37% of the emissions reductions needed to tackle climate change.
The Dasgupta Review-Independent Review on the Economics of Biodiversity reports that green infrastructure (salt marshes and mangroves) are 2-5 times cheaper than grey infrastructure (breakwaters).
Another study estimated that the annual gross carbon emissions from tropical tree cover loss between 2015 and 2017 was equivalent to 4.8 billion tonnes.
This causes more emissions each year than 85 million cars do in their lifetime. In 2019, approximately 34% of total net anthropogenic greenhouse gas emissions came from the energy supply sector, 24% from industry, 22% from agriculture, forestry and other land use, 15% from transport and 6% from buildings.
Conserving natural sinks
The IPCC Land Report estimates that land serves as a large CO2 sink. There is a growing body of evidence that a large proportion of the required removals could be achieved by conserving natural sinks, improving biodiversity protection, and restoring ecosystems.
Preserving earth’s cyclical processes by protecting terrestrial ecosystems and natural sinks and transformative agricultural practices under the leadership of indigenous people and local communities is a far more equitable and cost-effective way of tackling the climate crisis than it is being done now.
We need to realise that the climate crisis is just a symptom; our real problem is that human consumption and activity have exceeded the regenerative capacity of our planet. Technology, at best, can assist us, not lead us, on the pathway to a sustainable, regenerative and equitable world.

Petrol in India is cheaper than in countries like Hong Kong, Germany and the UK but costlier than in China, Brazil, Japan, the US, Russia, Pakistan and Sri Lanka, a Bank of Baroda Economics Research report showed.
Rising fuel prices in India have led to considerable debate on which government, state or central, should be lowering their taxes to keep prices under control.
The rise in fuel prices is mainly due to the global price of crude oil (raw material for making petrol and diesel) going up. Further, a stronger dollar has added to the cost of crude oil.
Amongst comparable countries (per capita wise), prices in India are higher than those in Vietnam, Kenya, Ukraine, Bangladesh, Nepal, Pakistan, Sri Lanka, and Venezuela. Countries that are major oil producers have much lower prices.
In the report, the Philippines has a comparable petrol price but has a per capita income higher than India by over 50 per cent.
Countries which have a lower per capita income like Kenya, Bangladesh, Nepal, Pakistan, and Venezuela have much lower prices of petrol and hence are impacted less than India.
“Therefore there is still a strong case for the government to consider lowering the taxes on fuel to protect the interest of the people,” the report argued.
India is the world’s third-biggest oil consuming and importing nation. It imports 85 per cent of its oil needs and so prices retail fuel at import parity rates.
With the global surge in energy prices, the cost of producing petrol, diesel and other petroleum products also went up for oil companies in India.
They raised petrol and diesel prices by Rs 10 a litre in just over a fortnight beginning March 22 but hit a pause button soon after as the move faced criticism and the opposition parties asked the government to cut taxes instead.
India imports most of its oil from a group of countries called the ‘OPEC +’ (i.e, Iran, Iraq, Saudi Arabia, Venezuela, Kuwait, United Arab Emirates, Russia, etc), which produces 40% of the world’s crude oil.
As they have the power to dictate fuel supply and prices, their decision of limiting the global supply reduces supply in India, thus raising prices
The government charges about 167% tax (excise) on petrol and 129% on diesel as compared to US (20%), UK (62%), Italy and Germany (65%).
The abominable excise duty is 2/3rd of the cost, and the base price, dealer commission and freight form the rest.
Here is an approximate break-up (in Rs):
a)Base Price | 39 |
b)Freight | 0.34 |
c) Price Charged to Dealers = (a+b) | 39.34 |
d) Excise Duty | 40.17 |
e) Dealer Commission | 4.68 |
f) VAT | 25.35 |
g) Retail Selling Price | 109.54 |
Looked closely, much of the cost of petrol and diesel is due to higher tax rate by govt, specifically excise duty.
So the question is why government is not reducing the prices ?
India, being a developing country, it does require gigantic amount of funding for its infrastructure projects as well as welfare schemes.
However, we as a society is yet to be tax-compliant. Many people evade the direct tax and that’s the reason why govt’s hands are tied. Govt. needs the money to fund various programs and at the same time it is not generating enough revenue from direct taxes.
That’s the reason why, govt is bumping up its revenue through higher indirect taxes such as GST or excise duty as in the case of petrol and diesel.
Direct taxes are progressive as it taxes according to an individuals’ income however indirect tax such as excise duty or GST are regressive in the sense that the poorest of the poor and richest of the rich have to pay the same amount.
Does not matter, if you are an auto-driver or owner of a Mercedes, end of the day both pay the same price for petrol/diesel-that’s why it is regressive in nature.
But unlike direct tax where tax evasion is rampant, indirect tax can not be evaded due to their very nature and as long as huge no of Indians keep evading direct taxes, indirect tax such as excise duty will be difficult for the govt to reduce, because it may reduce the revenue and hamper may programs of the govt.
Globally, around 80% of wastewater flows back into the ecosystem without being treated or reused, according to the United Nations.
This can pose a significant environmental and health threat.
In the absence of cost-effective, sustainable, disruptive water management solutions, about 70% of sewage is discharged untreated into India’s water bodies.
A staggering 21% of diseases are caused by contaminated water in India, according to the World Bank, and one in five children die before their fifth birthday because of poor sanitation and hygiene conditions, according to Startup India.
As we confront these public health challenges emerging out of environmental concerns, expanding the scope of public health/environmental engineering science becomes pivotal.
For India to achieve its sustainable development goals of clean water and sanitation and to address the growing demands for water consumption and preservation of both surface water bodies and groundwater resources, it is essential to find and implement innovative ways of treating wastewater.
It is in this context why the specialised cadre of public health engineers, also known as sanitation engineers or environmental engineers, is best suited to provide the growing urban and rural water supply and to manage solid waste and wastewater.
Traditionally, engineering and public health have been understood as different fields.
Currently in India, civil engineering incorporates a course or two on environmental engineering for students to learn about wastewater management as a part of their pre-service and in-service training.
Most often, civil engineers do not have adequate skills to address public health problems. And public health professionals do not have adequate engineering skills.
India aims to supply 55 litres of water per person per day by 2024 under its Jal Jeevan Mission to install functional household tap connections.
The goal of reaching every rural household with functional tap water can be achieved in a sustainable and resilient manner only if the cadre of public health engineers is expanded and strengthened.
In India, public health engineering is executed by the Public Works Department or by health officials.
This differs from international trends. To manage a wastewater treatment plant in Europe, for example, a candidate must specialise in wastewater engineering.
Furthermore, public health engineering should be developed as an interdisciplinary field. Engineers can significantly contribute to public health in defining what is possible, identifying limitations, and shaping workable solutions with a problem-solving approach.
Similarly, public health professionals can contribute to engineering through well-researched understanding of health issues, measured risks and how course correction can be initiated.
Once both meet, a public health engineer can identify a health risk, work on developing concrete solutions such as new health and safety practices or specialised equipment, in order to correct the safety concern..
There is no doubt that the majority of diseases are water-related, transmitted through consumption of contaminated water, vectors breeding in stagnated water, or lack of adequate quantity of good quality water for proper personal hygiene.
Diseases cannot be contained unless we provide good quality and adequate quantity of water. Most of the world’s diseases can be prevented by considering this.
Training our young minds towards creating sustainable water management systems would be the first step.
Currently, institutions like the Indian Institute of Technology, Madras (IIT-M) are considering initiating public health engineering as a separate discipline.
To leverage this opportunity even further, India needs to scale up in the same direction.
