Upcoming geological periods
With climate change ruling the environment discourse, the sudden warming of the Earth in contemporary times prompted an official expert group to present a recommendation to the International Geological Congress to declare the geological period beginning since 1950 as the Anthropocene epoch. Since 2009, the Working Group on the Anthropocene (WHA) has been working to set up a working model for the Anthropocene Epoch. The epoch would be said to mark the impact of modern civilization on the climate and environment of the Earth involving humankind’s impact on global climate.
The beginning of Anthropocene age, marked by the numerous nuclear tests and consequent detonations that had dispersed radioactivity in areas around the world, also would have to take into account for large-scale environmental effects caused by anthropogenic interventions such as plastic pollution, greenhouse gas emissions, environmental contamination, and several other effects. Although the changes have been said to be initiated, statigraphers cannot yet come to a conclusion on bringing changes to the geological time scale.
Talk of the Anthropocene epoch is taking place because the current epoch – the Holocene – is marked by largely stable climate over the last 12,000 years since the previous age – the Ice Age.
The Holocene epoch is the period within which all of human civilization developed, and many experts are calling for its end with large scale changes such as greenhouse gas emissions, sea level rise, development activities, destruction of ecosystems, and the extinction many animal species (Carrington, 2017), which should alter the planet to an extent similar in scale to a change in epoch, and is said to be principally manifested in its genesis as climate change. Human civilization has so far inhabited a planet that has seen no massive planetary shifts in climate, in a period of relative stability.
However, the changes that human intervention have initiated are so aberrant that it is expected that climate change will not be the only defining feature of this epoch, with the introduction of an incredible array of chemicals in the soil, water and atmosphere; and incredible changes to the geomorphology of the planet; that could change the entire biosphere at a pace not witnessed before in the history of life on Earth.
On the other hand, it is argued that new basis of planetary order could arise, such as the electronic medium, which for now is in the realm of popular science. The full effects of anthropogenic changes on the geology of the planet could have rather serious and tragic implications that until now have not been fully charted. However, based on trends in changes in geological periods, we can get a sense of one important aspect of the effects of anthropogenic interventions on transitional aspects of geological periods – climate change.
Climate Change and Geological Periods
The driving aspect of climate change is the rising up of the Earth’s temperatures by the accumulation of greenhouse gases, primarily CO2 in the atmosphere, which act to trap the solar heat that is reflected back from the Earth’s surface, leading to a rise in temperatures.
Although the Earth since its formation is said to be gradually cooling down cumulatively, in the more recent time scale since the Ice Age, temperatures have increased, although in the present Holocene epoch, they have remained quite stable in general. The comparative stability of plate tectonics in the last 50 million years allows geologists to better study geological periods since about this time.
These epochs thus fall within the broader period among geological periods called the Cenozoic Era. Generally the Earth has been cooling, and this follows a fairly warm period about 45 to 55 million years ago called the Eocene Optimum, when much of Antarctica was without an ice cover. The cooling process post the Eocene Optimum is said to have begun 34 million years ago during the Eocene-Oligocene boundary climate transition when due to the cooling of the Earth, an ice sheet had formed over Antarctica.
Atmospheric CO2 during this period is said to have fallen to below 750 ppm. Evidence from sedimentary cycles from the Ross Sea point towards glacial cycles between 34 to 31 million years (Galeotti et al., 2016).

However, within these epochal transitions, the Earth’s climate, including its temperature, showed wide variations. Going by fossil records, the Eocene Optimum displays evidence of an abundance of forest areas, with most species being species adapted to tropical conditions, although there were arid conditions as well.
In the Ice Age, although most species were those adapted to cold conditions, tropical species thrived in the lower latitudes. With changing climatic conditions over time, certain species adapted while others went extinct.
Climatic variations could be due to conditions on earth itself or due to extra-terrestrial reasons such as due to changes in the amount of heating provided by the Sun. Geological evidence however, makes a strong case for Earth’s own volition rather than in extra-terrestrial reasons. Climatic patterns have largely fluctuated somewhat even though the long term trend has been the cooling down of Earth.
For example, climate during the Ice Age was particularly unstable, with frequent temperature fluctuations ranging more than 10 degrees Fahrenheit. The fluctuations largely follow changes in the tilt of the Earth’s axis and in the shape formed when the Earth orbits the Sun.
These are defined as Milankovitch Cycles, and are caused by the gravitational forces in the Solar System caused by the Moon and other planets besides the Sun. However, Milankovitch Cycles do not result in as large of fluctuations in temperature as were said to have occurred over geological periods, unless there were factors on Earth, those influencing climatic patterns that would aggravate the warming effect. The Earth exhibits certain intrinsic characteristics that lead to a rise in temperatures and a change in climatic patterns between geological periods and within them, over time.
Due to bubbles containing air from the Ice Age preserved in glaciers in the Arctic and Antarctic, it is possible to evaluate the atmospheric composition of the period with certain accuracy. Evaluation of earlier geological periods is more difficult, and the composition of marine sediments as affected by oceanic CO2and studying its effect on fossilized leaves of plants from these geological periods are some examples of methods used to evaluate the atmospheric composition in these geological periods.
Although investigations reveal that the Earth’s overall cooling process has been accompanied by a gradual decrease in CO2 levels along with certain other greenhouse gases, their levels have fluctuated in between that have caused significant changes in the Earth’s climatic patterns.
CO2 levels during the extremely warm Eocene Optimum were said to be between 2,000 and 3,000 ppm while those for the much colder Ice Age are said to be about 200 ppm (Menke, 2014). In pre-industrial times in the current Holocene epoch, CO2 levels had reached to about 280 ppm. By 2016, the CO2 levels reached to over more than 400 ppm (Jones, 2017).
However, atmospheric CO2 is not the only determining factor in raising Earth’s temperatures. Other factors can also be involved such as other greenhouse gases, amounts of ice cover and persistent cloud cover, which reflect sunlight back into space, and other possible concomitants can be the amounts of areas on the Earth covered by forests and oceans, which absorb heat.
Although evidence is altogether unsatisfactory on whether greenhouses gases alone could have caused the high global temperature levels in the Eocene Optimum, rising to about 5 to 6 degrees Celsius above previous levels (De Conto et al., 2017), global climatic models suggest that such high levels of warming could only have occurred due to the proliferation of greenhouse gases.
This rise in temperatures during the Eocene Optimum eventually led to the melting of the polar ice caps, such that sea levels rose to 200 feet above previous levels (Menke, 2014). Data suggests that climate change, although slow to begin, could accelerate over time if left unchecked. A rise in greenhouse gas levels similar to previous warm epochs such as the Eocene Optimum, which was the warmest period in the Earth’s recent history, could be devastating for most living things not adapted to warm climates.
It is said that during the Eocene Optimum, cold-blooded creatures like crocodiles inhabited areas close to the polar regions such as present-day Greenland. Though there is uncertainty as regards the exact levels of CO2 during the geological period when the polar ice caps had largely melted, the rate of increase in CO2 levels can be determined based on cumulative estimates.
Modern levels of atmospheric CO2 are accelerating at a pace unprecedented in the history of previous geological periods. The annual rate of increase for atmospheric carbon di oxide levels in the late 1950’s was 0.7 ppm/ year, while between the years 2005 to 2014 this had increased to 2.1 ppm/ year.
Although the effects are slow to be realized, with the IPCC predicting the possibility of a rise in global temperatures by 3 degrees Celsius by 2080 (Jones, 2017), the longer term effects with an increasing rate of acceleration in global atmospheric CO2 levels could have devastating effects on the Earth’s climatic patterns.
A full estimate of the effects of this process cannot be definitively ascertained due to the vastness of the scope, but there is no doubt that this uncertainty adds to the need to form better estimates of the effects, which are extremely difficult to define and attribute. Although we know that global CO2 levels annually are accelerating, there cannot be any estimates over how the trends are going to play out in the coming years. Without a global concerted effort towards checking carbon emissions, humankind is exploring uncharted territory. The in depth study of geological periods although should help us better understand the effects of climate change.

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.
Consider this hypothetical situation: Rajalakshmi, from a remote Karnataka village spots a business opportunity.
She knows that flowers, discarded in the thousands by temples can be handcrafted into incense sticks.
She wants to find a market for the product and hopefully, employ some people to help her. Soon enough though, she discovers that starting a business is a herculean task for a person like her.
There is a laborious process of rules and regulations to go through, bribes to pay on the way and no actual means to transport her product to its market.
After making her first batch of agarbathis and taking it to Bengaluru by bus, she decides the venture is not easy and gives up.
On the flipside of this is a young entrepreneur in Bengaluru. Let’s call him Deepak. He wants to start an internet-based business selling sustainably made agarbathis.
He has no trouble getting investors and to mobilise supply chains. His paperwork is over in a matter of days and his business is set up quickly and ready to grow.
Never mind that the business is built on aggregation of small sellers who will not see half the profit .
Is this scenario really all that hypothetical or emblematic of how we think about entrepreneurship in India?
Between our national obsession with unicorns on one side and glorifying the person running a pakora stall for survival as an example of viable entrepreneurship on the other, is the middle ground in entrepreneurship—a space that should have seen millions of thriving small and medium businesses, but remains so sparsely occupied that you could almost miss it.
If we are to achieve meaningful economic growth in our country, we need to incorporate, in our national conversation on entrepreneurship, ways of addressing the missing middle.
Spread out across India’s small towns and cities, this is a class of entrepreneurs that have been hit by a triple wave over the last five years, buffeted first by the inadvertent fallout of demonetization, being unprepared for GST, and then by the endless pain of the covid-19 pandemic.
As we finally appear to be reaching some level of normality, now is the opportune time to identify the kind of industries that make up this layer, the opportunities they should be afforded, and the best ways to scale up their functioning in the shortest time frame.
But, why pay so much attention to these industries when we should be celebrating, as we do, our booming startup space?
It is indeed true that India has the third largest number of unicorns in the world now, adding 42 in 2021 alone. Braving all the disruptions of the pandemic, it was a year in which Indian startups raised $24.1 billion in equity investments, according to a NASSCOM-Zinnov report last year.
However, this is a story of lopsided growth.
The cities of Bengaluru, Delhi/NCR, and Mumbai together claim three-fourths of these startup deals while emerging hubs like Ahmedabad, Coimbatore, and Jaipur account for the rest.
This leap in the startup space has created 6.6 lakh direct jobs and a few million indirect jobs. Is that good enough for a country that sends 12 million fresh graduates to its workforce every year?
It doesn’t even make a dent on arguably our biggest unemployment in recent history—in April 2020 when the country shutdown to battle covid-19.
Technology-intensive start-ups are constrained in their ability to create jobs—and hybrid work models and artificial intelligence (AI) have further accelerated unemployment.
What we need to focus on, therefore, is the labour-intensive micro, small and medium enterprise (MSME). Here, we begin to get to a definitional notion of what we called the mundane middle and the problems it currently faces.
India has an estimated 63 million enterprises. But, out of 100 companies, 95 are micro enterprises—employing less than five people, four are small to medium and barely one is large.
The questions to ask are: why are Indian MSMEs failing to grow from micro to small and medium and then be spurred on to make the leap into large companies?
At the Global Alliance for Mass Entrepreneurship (GAME), we have advocated for a National Mission for Mass Entrepreneurship, the need for which is more pronounced now than ever before.
Whenever India has worked to achieve a significant economic milestone in a limited span of time, it has worked best in mission mode. Think of the Green Revolution or Operation Flood.
From across various states, there are enough examples of approaches that work to catalyse mass entrepreneurship.
The introduction of entrepreneurship mindset curriculum (EMC) in schools through alliance mode of working by a number of agencies has shown significant improvement in academic and life outcomes.
Through creative teaching methods, students are encouraged to inculcate 21st century skills like creativity, problem solving, critical thinking and leadership which are not only foundational for entrepreneurship but essential to thrive in our complex world.
Udhyam Learning Foundation has been involved with the Government of Delhi since 2018 to help young people across over 1,000 schools to develop an entrepreneurial mindset.
One pilot programme introduced the concept of ‘seed money’ and saw 41 students turn their ideas into profit-making ventures. Other programmes teach qualities like grit and resourcefulness.
If you think these are isolated examples, consider some larger data trends.
The Observer Research Foundation and The World Economic Forum released the Young India and Work: A Survey of Youth Aspirations in 2018.
When asked which type of work arrangement they prefer, 49% of the youth surveyed said they prefer a job in the public sector.
However, 38% selected self-employment as an entrepreneur as their ideal type of job. The spirit of entrepreneurship is latent and waiting to be unleashed.
The same can be said for building networks of successful women entrepreneurs—so crucial when the participation of women in the Indian economy has declined to an abysmal 20%.
The majority of India’s 63 million firms are informal —fewer than 20% are registered for GST.
Research shows that companies that start out as formal enterprises become two-three times more productive than a similar informal business.
So why do firms prefer to be informal? In most cases, it’s because of the sheer cost and difficulty of complying with the different regulations.
We have academia and non-profits working as ecosystem enablers providing insights and evidence-based models for growth. We have large private corporations and philanthropic and funding agencies ready to invest.
It should be in the scope of a National Mass Entrepreneurship Mission to bring all of them together to work in mission mode so that the gap between thought leadership and action can finally be bridged.
Heat wave is a condition of air temperature which becomes fatal to human body when exposed. Often times, it is defined based on the temperature thresholds over a region in terms of actual temperature or its departure from normal.
Heat wave is considered if maximum temperature of a station reaches at least 400C or more for Plains and at least 300C or more for Hilly regions.
a) Based on Departure from Normal
Heat Wave: Departure from normal is 4.50C to 6.40C
Severe Heat Wave: Departure from normal is >6.40C
b) Based on Actual Maximum Temperature
Heat Wave: When actual maximum temperature ≥ 450C
Severe Heat Wave: When actual maximum temperature ≥470C
If above criteria met at least in 2 stations in a Meteorological sub-division for at least two consecutive days and it declared on the second day
It is occurring mainly during March to June and in some rare cases even in July. The peak month of the heat wave over India is May.
Heat wave generally occurs over plains of northwest India, Central, East & north Peninsular India during March to June.
It covers Punjab, Haryana, Delhi, Uttar Pradesh, Bihar, Jharkhand, West Bengal, Odisha, Madhya Pradesh, Rajasthan, Gujarat, parts of Maharashtra & Karnataka, Andhra Pradesh and Telengana.
Sometimes it occurs over Tamilnadu & Kerala also.
Heat waves adversely affect human and animal lives.
However, maximum temperatures more than 45°C observed mainly over Rajasthan and Vidarbha region in month of May.
a. Transportation / Prevalence of hot dry air over a region (There should be a region of warm dry air and appropriate flow pattern for transporting hot air over the region).
b. Absence of moisture in the upper atmosphere (As the presence of moisture restricts the temperature rise).
c. The sky should be practically cloudless (To allow maximum insulation over the region).
d. Large amplitude anti-cyclonic flow over the area.
Heat waves generally develop over Northwest India and spread gradually eastwards & southwards but not westwards (since the prevailing winds during the season are westerly to northwesterly).
The health impacts of Heat Waves typically involve dehydration, heat cramps, heat exhaustion and/or heat stroke. The signs and symptoms are as follows:
1. Heat Cramps: Ederna (swelling) and Syncope (Fainting) generally accompanied by fever below 39*C i.e.102*F.
2. Heat Exhaustion: Fatigue, weakness, dizziness, headache, nausea, vomiting, muscle cramps and sweating.
3. Heat Stoke: Body temperatures of 40*C i.e. 104*F or more along with delirium, seizures or coma. This is a potential fatal condition.

Political independence does not have much meaning without economic independence.
One of the important indicators of economic independence is self-sufficiency in food grain production.
The overall food grain scenario in India has undergone a drastic transformation in the last 75 years.
India was a food-deficit country on the eve of Independence. It had to import foodgrains to feed its people.
The situation became more acute during the 1960s. The imported food had to be sent to households within the shortest possible time.
The situation was referred to as ‘ship to mouth’.
Presently, Food Corporation of India (FCI) godowns are overflowing with food grain stocks and the Union government is unable to ensure remunerative price to the farmers for their produce.
This transformation, however, was not smooth.
In the 1960s, it was disgraceful, but unavoidable for the Prime Minister of India to go to foreign countries with a begging bowl.
To avoid such situations, the government motivated agricultural scientists to make India self-sufficient in food grain production.
As a result, high-yield varieties (HYV) were developed. The combination of seeds, water and fertiliser gave a boost to food grain production in the country which is generally referred to as the Green Revolution.
The impact of the Green Revolution, however, was confined to a few areas like Punjab, Haryana, western Uttar Pradesh in the north and (unified) Andhra Pradesh in the south.
Most of the remaining areas were deficit in food grain production.
Therefore the Union government had to procure food grain from surplus states to distribute it among deficit ones.
At the time, farmers in the surplus states viewed procurement as a tax as they were prevented from selling their surplus foodgrains at high prices in the deficit states.
As production of food grains increased, there was decentralisation of procurement. State governments were permitted to procure grain to meet their requirement.
The distribution of food grains was left to the concerned state governments.
Kerala, for instance, was totally a deficit state and had to adopt a distribution policy which was almost universal in nature.
Some states adopted a vigorous public distribution system (PDS) policy.
It is not out of place to narrate an interesting incident regarding food grain distribution in Andhra Pradesh. The Government of Andhra Pradesh in the early 1980s implemented a highly subsidised rice scheme under which poor households were given five kilograms of rice per person per month, subject to a ceiling of 25 kilograms at Rs 2 per kg. The state government required two million tonnes of rice to implement the scheme. But it received only on one million tonne from the Union government.
The state government had to purchase another million tonne of rice from rice millers in the state at a negotiated price, which was higher than the procurement price offered by the Centre, but lower than the open market price.
A large number of studies have revealed that many poor households have been excluded from the PDS network, while many undeserving households have managed to get benefits from it.
Various policy measures have been implemented to streamline PDS. A revamped PDS was introduced in 1992 to make food grain easily accessible to people in tribal and hilly areas, by providing relatively higher subsidies.
Targeted PDS was launched in 1997 to focus on households below the poverty line (BPL).
Antyodaya Anna Yojana (AAY) was introduced to cover the poorest of the poor.
Annapoorna Scheme was introduced in 2001 to distribute 10 kg of food grains free of cost to destitutes above the age of 65 years.
In 2013, the National Food Security Act (NFSA) was passed by Parliament to expand and legalise the entitlement.
Conventionally, a card holder has to go to a particular fair price shop (FPS) and that particular shop has to be open when s/he visits it. Stock must be available in the shop. The card holder should also have sufficient time to stand in the queue to purchase his quota. The card holder has to put with rough treatment at the hands of a FPS dealer.
These problems do not exist once ration cards become smart cards. A card holder can go to any shop which is open and has available stocks. In short, the scheme has become card holder-friendly and curbed the monopoly power of the FPS dealer. Some states other than Chhattisgarh are also trying to introduce such a scheme on an experimental basis.
More recently, the Government of India has introduced a scheme called ‘One Nation One Ration Card’ which enables migrant labourers to purchase rations from the place where they reside. In August 2021, it was operational in 34 states and Union territories.
The intentions of the scheme are good but there are some hurdles in its implementation which need to be addressed. These problems arise on account of variation in:
It is not clear whether a migrant labourer gets items provided in his/her native state or those in the state s/he has migrated to and what prices will s/he be able to purchase them.
The Centre must learn lessons from the experiences of different countries in order to make PDS sustainable in the long-run.
For instance, Sri Lanka recently shifted to organic manure from chemical fertiliser without required planning. Consequently, it had to face an acute food shortage due to a shortage of organic manure.
Some analysts have cautioned against excessive dependence on chemical fertiliser.
Phosphorus is an important input in the production of chemical fertiliser and about 70-80 per cent of known resources of phosphorus are available only in Morocco.
There is possibility that Morocco may manipulate the price of phosphorus.
Providing excessive subsidies and unemployment relief may make people dependent, as in the case of Venezuela and Zimbabwe.
It is better to teach a person how to catch a fish rather than give free fish to him / her.
Hence, the government should give the right amount of subsidy to deserving people.
The government has to increase livestock as in the case of Uruguay to make the food basket broad-based and nutritious. It has to see to it that the organic content in the soil is adequate, in order to make cultivation environmentally-friendly and sustainable in the long-run.
In short, India has transformed from a food-deficit state to a food-surplus one 75 years after independence. However, the government must adopt environmental-friendly measures to sustain this achievement.
Agroforestry is an intentional integration of trees on farmland.
Globally, it is practised by 1.2 billion people on 10 per cent area of total agricultural lands (over 1 billion hectares).
It is widely popular as ‘a low hanging fruit’ due to its multifarious tangible and intangible benefits.
The net carbon sequestered in agroforestry is 11.35 tonnes of carbon per ha
A panacea for global issues such as climate change, land degradation, pollution and food security, agroforestry is highlighted as a key strategy to fulfil several targets:
In 2017, a New York Times bestseller Project Drawdown published by 200 scientists around the world with a goal of reversing climate change, came up with the most plausible 100 solutions to slash–down greenhouse gas (GHG) emissions.
Out of these 100 solutions, 11 strategies were highlighted under the umbrella of agroforestry such as:-
Nowadays, tree-based farming in India is considered a silver bullet to cure all issues.
It was promoted under the Green India mission of 2001, six out of eight missions under the National Action Plan on Climate Change (NAPCC) and National Agroforestry and Bamboo Mission (NABM), 2017 to bring a third of the geographical area under tree cover and offsetting GHG emissions.
These long-term attempts by the Government of India have helped enhance the agroforestry area to 13.75 million hectares.
The net carbon sequestered in agroforestry is 11.35 tonnes of carbon per ha and carbon sequestration potential is 0.35 tonnes of carbon per ha per year at the country level, according to the Central Agroforestry Research Institute, Jhansi.
India will reduce an additional 2.5-3 billion tonnes of CO2 by increasing tree cover. This extra tree cover could be achieved through agroforestry systems because of their ability to withstand minimum inputs under extreme situations.
Here are some examples which portray the role of agroforestry in achieving at least nine out of the 17 SDGs through sustainable food production, ecosystem services and economic benefits:
SDG 1 — No Poverty: Almost 736 million people still live in extreme poverty. Diversification through integrating trees in agriculture unlocks the treasure to provide multifunctional benefits.
Studies carried out in 2003 in the arid regions of India reported a 10-15 per cent increase in crop yield with Prosopis cineraria (khejari). Adoption of agroforestry increases income & production by reducing the cost of input & production.
SDG 2 — Zero hunger: Tree-based systems provide food and monetary returns. Traditional agroforestry systems like Prosopis cineraria and Madhuca longifolia (Mahua) provide edible returns during drought years known as “lifeline to the poor people”.
Studies showed that 26-50 per cent of households involved in tree products collection and selling act as a coping strategy to deal with hunger.
SDG 3 — Good health and well-being: Human wellbeing and health are depicted through the extent of healthy ecosystems and services they provide.
Agroforestry contributes increased access to diverse nutritious food, supply of medicine, clean air and reduces heat stress.
Vegetative buffers can filter airstreams of particulates by removing dust, gas, microbial constituents and heavy metals.
SDG 5 — Gender equality: Throughout the world around 3 billion people depend on firewood for cooking.
In this, women are the main collectors and it brings drudgery and health issues.
A study from India stated that almost 374 hours per year are spent by women for collection of firewood. Growing trees nearby provides easy access to firewood and diverts time to productive purposes.
SDG 6 — Clean Water and Sanitation: Water is probably the most vital resource for our survival. The inherent capacity of trees offers hydrological regulation as evapotranspiration recharges atmospheric moisture for rainfall; enhanced soil infiltration recharges groundwater; obstructs sediment flow; rainwater filtration by accumulation of heavy metals.
An extensive study in 35 nations published in 2017 concluded that 30 per cent of tree cover in watersheds resulted in improved sanitisation and reduced diarrheal disease.
SDG 7 — Affordable & Clean Energy: Wood fuels are the only source of energy to billions of poverty-stricken people.
Though trees are substitutes of natural forests, modern technologies in the form of biofuels, ethanol, electricity generation and dendro-biomass sources are truly affordable and clean.
Ideal agroforestry models possess fast-growing, high coppicing, higher calorific value and short rotation (2-3 years) characteristics and provide biomass of 200-400 tonnes per ha.
SDG 12 — Responsible consumption and production: The production of agricultural and wood-based commodities on a sustainable basis without depleting natural resources and as low as external inputs (chemical fertilisers and pesticides) to reduce the ecological footprints.
SDG 13 — Climate action: Globally, agricultural production accounts for up to 24 per cent of GHG emissions from around 22.2 million square km of agricultural area, according to the Food and Agriculture Organization.
A 2016 study depicted that conversion of agricultural land to agroforestry sequesters about 27.2± 13.5 tonnes CO2 equivalent per ha per year after establishment of systems.
Trees on farmland mitigate 109.34 million tonnes CO2 equivalent annually from 15.31 million ha, according to a 2017 report. This may offset a third of the total GHG emissions from the agriculture sector of India.
SDG 15 — Life on Land: Agroforestry ‘mimics the forest ecosystem’ to contribute conservation of flora and faunas, creating corridors, buffers to existing reserves and multi-functional landscapes.
Delivery of ecosystem services of trees regulates life on land. A one-hectare area of homegardens in Kerala was found to have 992 trees from 66 species belonging to 31 families, a recent study showed.
The report of the World Agroforestry Centre highlighted those 22 countries that have registered agroforestry as a key strategy in achieving their unconditional national contributions.
Recently, the Government of India has allocated significant financial support for promotion of agroforestry at grassroot level to make the Indian economy as carbon neutral. This makes agroforestry a low-hanging fruit to achieve the global goals.
