The ozone layer is a belt of naturally occurring ozone gas in the stratosphere. It absorbs the harmful ultraviolet radiations emitted from the sun before it reaches the Earth’s atmosphere. Ozone depleting substances (ODS) like CFCs and other organic substances that are used in appliances are responsible for the depletion and thinning of ozone layer.
The Montreal Protocol is an international treaty signed to protect the ozone layer where the parties agreed to phase out production of ODSs. It has proved to be one of the most successful international treaties as the ozone layer is slowly reviving and the ozone hole over Antarctica is also healing.
The occurrence of ozone
Ozone is present in a very small amount in the Earth’s atmosphere, averaging about three molecules of ozone for every ten million molecules of air. It is measured in Dobson Unit (Db) which is equivalent to a 0.01 mm thickness of pure ozone if brought down to ground level pressure (1 atm) and temperature (0°C). The global average of ozone thickness is about 300Db.
Most of the ozone, around 90 per cent, resides in the upper layer of atmosphere called the stratosphere, which is 10 km above the Earth’s surface. It forms a blanket like structure around the Earth’s atmosphere called the ‘ozone layer’. The remaining 10 per cent is present in the lower region of the atmosphere, commonly known as the troposphere. The ozone layer filters out the harmful ultraviolet (UV) radiations from the sun before reaching the Earth by absorbing them. Thus, it is also known as the ‘Earth’s natural sunscreen’.
The role of ozone in the two regions of the atmosphere is different. The stratospheric ozone is called as the ‘good ozone’ due to its role in shielding the biologically damaging ultraviolet sunlight (called UV-B). Whereas, tropospheric ozone is known as ‘bad ozone’ because of its highly reactive nature with other gas molecules and it is toxic for living systems. Surface ozone is also a key component in formation of photochemical smog which is a potential air pollutant. Therefore, ozone basically has two environmental issues – the increasing concentration of ozone in the troposphere and the depletion of ozone layer in the stratosphere due to the release of several ozone-depleting substances (ODS).
Depletion of Ozone layer
The ozone molecules in the stratosphere are constantly formed and destroyed during any given time. Thus, the concentration of ozone is supposed to remain relatively stable unless the chemistry is drastically disturbed by external factors. In the beginning of the 1970s, the scientific community discovered that the ozone layer has been depleting more quickly than it is naturally formed. It was due to the human produced ozone-depleting organic compounds generally identified as halocarbons. They are combinations of elements like chlorine, bromine, fluorine, oxygen and hydrogen. Collectively they are known as Chlorofluorocarbons (CFCs) and Hydroclorofluorocarbons (HCFCs). Other ozone depleting substances are carbon tetrachloride, methyl chloroform and methyl bromide. These substances are non-reactive, non-flammable and non-toxic and can travel for a long distance reaching up to the stratosphere in a few years.
In the presence of UV light they produce free chlorine, fluorine and bromine which when in contact with ozone break down their molecules. It is estimated that, one chlorine molecule can destroy 100,000 ozone molecules before it is removed from the stratosphere (Environmental Protection Agency, US, 2016). ODSs are used in our day today appliances like refrigerators, air conditioners, fire extinguishers, foam insulators etc. The use of these substances is banned legally in most of the countries but illegal use is still widespread.
Finding a replacement for CFCs became inevitable and with effort the global scientific community found substances which are less harmful than CFCs. Hydrochlorofluorocarbons (HCFCs) are one of the temporary replacements for CFCs, while Hydroflourocarbons (HFCs) are the main long term replacements for CFCs and HCFCs. Since chlorine has the highest potential to destroy ozone, products that are entirely free of chlorine will be the ultimate replacements for CFCs and HCFCs.
The growing awareness of the serious impacts of ODSs in the ozone layer led to the groundbreaking Montreal Protocol on Substances that Deplete the Ozone Layer which was signed in 1987. It was the first joint international effort to protect the stratospheric ozone. The parties under the Protocol decided to phase out CFCs and halon productions. The measures taken up under this agreement was met with positive results as ODSs are falling and the ozone layer is expected to be fully healed near the middle of the 21st century (USEPA, 2017).

Biological impacts of ozone depletion
Most of the biological impacts of ozone layer depletion are due to the damaging nature of UV-B radiations. The reduction of ozone concentration in the stratosphere allows more UV-B radiations to penetrate into the Earth’s atmosphere. Research says that 1 per cent decrease in ozone overhead can result in a 2 per cent increase in UV-B intensity at ground level (Baird and Cann, 2008). The DNA molecules of a living body absorb the UV radiation and can cause several genetic aberrations. It can be linked to several human conditions like skin cancers, cataracts, macular degeneration (gradual death of retinal cells) etc. Malignant melanoma is a widespread skin cancer caused by over-exposure to UV-B radiations. The impacts of UV-B radiation is confined not only to humans but plants as well. The efficiency of plant photosynthesis is reduced leading to less leaves, fruits and seeds. It also affects the production of microscopic phytoplankton which is an important base in the marine food chain.
The tropospheric ozone also has multiple effects on food production, forest growth and human health. It aggravates various respiratory diseases like asthma and emphysema, and is also linked to permanent lung damage. In plants, ozone induces early senescence and abscission of leaves, it also reduces the rate of photosynthetic carbon fixation and thereby a decrease in fruit and seed production (Wilkinson et al., 2012).
Healing of ozone hole in Antarctica
The ozone hole in Antarctica is not an actual hole but an area of exceptionally thin layer of ozone at the stratosphere that happens during the Southern Hemisphere Spring (August-October). This is due to the formation of Polar Stratospheric Clouds (PSC) particles during the winter. The inactive form of chlorine is converted into active form (Chlorine gas) in the presence of water and ice. Thus when spring comes, sunlight breaks the bond between two chlorine atoms which are in active form and undergoes a series of catalytic ozone destructions. The ozone hole grows throughout spring until the cold polar vortex vanishes and stabilizes the ozone layer. This cycle repeats each year during the spring.
On the bright side, research and monitoring have shown that the ozone hole over Antarctica has started to heal. It was reported in 2015 that the hole was around 14 million sq km smaller than it was in the year 2000, an area roughly the size of India (Solomon et al. 2016). This milestone has been credited to the international joint efforts in phasing out of ozone depleting substances. Meanwhile, researchers say that even though production of ODSs has been phased out in many countries, there is still plenty of chlorine left in the atmosphere. It is expected that complete recovery of ozone depletion would happen by around 2050-60 owing to the long lifetime and slow decay of chlorine.

On March 31, the World Economic Forum (WEF) released its annual Gender Gap Report 2021. The Global Gender Gap report is an annual report released by the WEF. The gender gap is the difference between women and men as reflected in social, political, intellectual, cultural, or economic attainments or attitudes. The gap between men and women across health, education, politics, and economics widened for the first time since records began in 2006.
[wptelegram-join-channel link=”https://t.me/s/upsctree” text=”Join @upsctree on Telegram”]No need to remember all the data, only pick out few important ones to use in your answers.
The Global gender gap index aims to measure this gap in four key areas : health, education, economics, and politics. It surveys economies to measure gender disparity by collating and analyzing data that fall under four indices : economic participation and opportunity, educational attainment, health and survival, and political empowerment.
The 2021 Global Gender Gap Index benchmarks 156 countries on their progress towards gender parity. The index aims to serve as a compass to track progress on relative gaps between women and men in health, education, economy, and politics.
Although no country has achieved full gender parity, the top two countries (Iceland and Finland) have closed at least 85% of their gap, and the remaining seven countries (Lithuania, Namibia, New Zealand, Norway, Sweden, Rwanda, and Ireland) have closed at least 80% of their gap. Geographically, the global top 10 continues to be dominated by Nordic countries, with —Iceland, Norway, Finland, and Sweden—in the top five.
The top 10 is completed by one country from Asia Pacific (New Zealand 4th), two Sub-Saharan countries (Namibia, 6th and Rwanda, 7th, one country from Eastern Europe (the new entrant to the top 10, Lithuania, 8th), and another two Western European countries (Ireland, 9th, and Switzerland, 10th, another country in the top-10 for the first time).There is a relatively equitable distribution of available income, resources, and opportunities for men and women in these countries. The tremendous gender gaps are identified primarily in the Middle East, Africa, and South Asia.
Here, we can discuss the overall global gender gap scores across the index’s four main components : Economic Participation and Opportunity, Educational Attainment, Health and Survival, and Political Empowerment.
The indicators of the four main components are
(1) Economic Participation and Opportunity:
o Labour force participation rate,
o wage equality for similar work,
o estimated earned income,
o Legislators, senior officials, and managers,
o Professional and technical workers.
(2) Educational Attainment:
o Literacy rate (%)
o Enrollment in primary education (%)
o Enrollment in secondary education (%)
o Enrollment in tertiary education (%).
(3) Health and Survival:
o Sex ratio at birth (%)
o Healthy life expectancy (years).
(4) Political Empowerment:
o Women in Parliament (%)
o Women in Ministerial positions (%)
o Years with a female head of State (last 50 years)
o The share of tenure years.
The objective is to shed light on which factors are driving the overall average decline in the global gender gap score. The analysis results show that this year’s decline is mainly caused by a reversal in performance on the Political Empowerment gap.
Global Trends and Outcomes:
– Globally, this year, i.e., 2021, the average distance completed to gender parity gap is 68% (This means that the remaining gender gap to close stands at 32%) a step back compared to 2020 (-0.6 percentage points). These figures are mainly driven by a decline in the performance of large countries. On its current trajectory, it will now take 135.6 years to close the gender gap worldwide.
– The gender gap in Political Empowerment remains the largest of the four gaps tracked, with only 22% closed to date, having further widened since the 2020 edition of the report by 2.4 percentage points. Across the 156 countries covered by the index, women represent only 26.1% of some 35,500 Parliament seats and 22.6% of over 3,400 Ministers worldwide. In 81 countries, there has never been a woman head of State as of January 15, 2021. At the current rate of progress, the World Economic Forum estimates that it will take 145.5 years to attain gender parity in politics.
– The gender gap in Economic Participation and Opportunity remains the second-largest of the four key gaps tracked by the index. According to this year’s index results, 58% of this gap has been closed so far. The gap has seen marginal improvement since the 2020 edition of the report, and as a result, we estimate that it will take another 267.6 years to close.
– Gender gaps in Educational Attainment and Health and Survival are nearly closed. In Educational Attainment, 95% of this gender gap has been closed globally, with 37 countries already attaining gender parity. However, the ‘last mile’ of progress is proceeding slowly. The index estimates that it will take another 14.2 years to close this gap on its current trajectory completely.
In Health and Survival, 96% of this gender gap has been closed, registering a marginal decline since last year (not due to COVID-19), and the time to close this gap remains undefined. For both education and health, while progress is higher than economy and politics in the global data, there are important future implications of disruptions due to the pandemic and continued variations in quality across income, geography, race, and ethnicity.
India-Specific Findings:
India had slipped 28 spots to rank 140 out of the 156 countries covered. The pandemic causing a disproportionate impact on women jeopardizes rolling back the little progress made in the last decades-forcing more women to drop off the workforce and leaving them vulnerable to domestic violence.
India’s poor performance on the Global Gender Gap report card hints at a serious wake-up call and learning lessons from the Nordic region for the Government and policy makers.
Within the 156 countries covered, women hold only 26 percent of Parliamentary seats and 22 percent of Ministerial positions. India, in some ways, reflects this widening gap, where the number of Ministers declined from 23.1 percent in 2019 to 9.1 percent in 2021. The number of women in Parliament stands low at 14.4 percent. In India, the gender gap has widened to 62.5 %, down from 66.8% the previous year.
It is mainly due to women’s inadequate representation in politics, technical and leadership roles, a decrease in women’s labor force participation rate, poor healthcare, lagging female to male literacy ratio, and income inequality.
The gap is the widest on the political empowerment dimension, with economic participation and opportunity being next in line. However, the gap on educational attainment and health and survival has been practically bridged.
India is the third-worst performer among South Asian countries, with Pakistan and Afghanistan trailing and Bangladesh being at the top. The report states that the country fared the worst in political empowerment, regressing from 23.9% to 9.1%.
Its ranking on the health and survival dimension is among the five worst performers. The economic participation and opportunity gap saw a decline of 3% compared to 2020, while India’s educational attainment front is in the 114th position.
India has deteriorated to 51st place from 18th place in 2020 on political empowerment. Still, it has slipped to 155th position from 150th position in 2020 on health and survival, 151st place in economic participation and opportunity from 149th place, and 114th place for educational attainment from 112th.
In 2020 reports, among the 153 countries studied, India is the only country where the economic gender gap of 64.6% is larger than the political gender gap of 58.9%. In 2021 report, among the 156 countries, the economic gender gap of India is 67.4%, 3.8% gender gap in education, 6.3% gap in health and survival, and 72.4% gender gap in political empowerment. In health and survival, the gender gap of the sex ratio at birth is above 9.1%, and healthy life expectancy is almost the same.
Discrimination against women has also been reflected in Health and Survival subindex statistics. With 93.7% of this gap closed to date, India ranks among the bottom five countries in this subindex. The wide sex ratio at birth gaps is due to the high incidence of gender-based sex-selective practices. Besides, more than one in four women has faced intimate violence in her lifetime.The gender gap in the literacy rate is above 20.1%.
Yet, gender gaps persist in literacy : one-third of women are illiterate (34.2%) than 17.6% of men. In political empowerment, globally, women in Parliament is at 128th position and gender gap of 83.2%, and 90% gap in a Ministerial position. The gap in wages equality for similar work is above 51.8%. On health and survival, four large countries Pakistan, India, Vietnam, and China, fare poorly, with millions of women there not getting the same access to health as men.
The pandemic has only slowed down in its tracks the progress India was making towards achieving gender parity. The country urgently needs to focus on “health and survival,” which points towards a skewed sex ratio because of the high incidence of gender-based sex-selective practices and women’s economic participation. Women’s labour force participation rate and the share of women in technical roles declined in 2020, reducing the estimated earned income of women, one-fifth of men.
Learning from the Nordic region, noteworthy participation of women in politics, institutions, and public life is the catalyst for transformational change. Women need to be equal participants in the labour force to pioneer the societal changes the world needs in this integral period of transition.
Every effort must be directed towards achieving gender parallelism by facilitating women in leadership and decision-making positions. Social protection programmes should be gender-responsive and account for the differential needs of women and girls. Research and scientific literature also provide unequivocal evidence that countries led by women are dealing with the pandemic more effectively than many others.
Gendered inequality, thereby, is a global concern. India should focus on targeted policies and earmarked public and private investments in care and equalized access. Women are not ready to wait for another century for equality. It’s time India accelerates its efforts and fight for an inclusive, equal, global recovery.
India will not fully develop unless both women and men are equally supported to reach their full potential. There are risks, violations, and vulnerabilities women face just because they are women. Most of these risks are directly linked to women’s economic, political, social, and cultural disadvantages in their daily lives. It becomes acute during crises and disasters.
With the prevalence of gender discrimination, and social norms and practices, women become exposed to the possibility of child marriage, teenage pregnancy, child domestic work, poor education and health, sexual abuse, exploitation, and violence. Many of these manifestations will not change unless women are valued more.
[wptelegram-join-channel link=”https://t.me/s/upsctree” text=”Join @upsctree on Telegram”]2021 WEF Global Gender Gap report, which confirmed its 2016 finding of a decline in worldwide progress towards gender parity.
Over 2.8 billion women are legally restricted from having the same choice of jobs as men. As many as 104 countries still have laws preventing women from working in specific jobs, 59 countries have no laws on sexual harassment in the workplace, and it is astonishing that a handful of countries still allow husbands to legally stop their wives from working.
Globally, women’s participation in the labour force is estimated at 63% (as against 94% of men who participate), but India’s is at a dismal 25% or so currently. Most women are in informal and vulnerable employment—domestic help, agriculture, etc—and are always paid less than men.
Recent reports from Assam suggest that women workers in plantations are paid much less than men and never promoted to supervisory roles. The gender wage gap is about 24% globally, and women have lost far more jobs than men during lockdowns.
The problem of gender disparity is compounded by hurdles put up by governments, society and businesses: unequal access to social security schemes, banking services, education, digital services and so on, even as a glass ceiling has kept leadership roles out of women’s reach.
Yes, many governments and businesses had been working on parity before the pandemic struck. But the global gender gap, defined by differences reflected in the social, political, intellectual, cultural and economic attainments or attitudes of men and women, will not narrow in the near future without all major stakeholders working together on a clear agenda—that of economic growth by inclusion.
The WEF report estimates 135 years to close the gap at our current rate of progress based on four pillars: educational attainment, health, economic participation and political empowerment.
India has slipped from rank 112 to 140 in a single year, confirming how hard women were hit by the pandemic. Pakistan and Afghanistan are the only two Asian countries that fared worse.
Here are a few things we must do:
One, frame policies for equal-opportunity employment. Use technology and artificial intelligence to eliminate biases of gender, caste, etc, and select candidates at all levels on merit. Numerous surveys indicate that women in general have a better chance of landing jobs if their gender is not known to recruiters.
Two, foster a culture of gender sensitivity. Take a review of current policies and move from gender-neutral to gender-sensitive. Encourage and insist on diversity and inclusion at all levels, and promote more women internally to leadership roles. Demolish silos to let women grab potential opportunities in hitherto male-dominant roles. Work-from-home has taught us how efficiently women can manage flex-timings and productivity.
Three, deploy corporate social responsibility (CSR) funds for the education and skilling of women and girls at the bottom of the pyramid. CSR allocations to toilet building, the PM-Cares fund and firms’ own trusts could be re-channelled for this.
Four, get more women into research and development (R&D) roles. A study of over 4,000 companies found that more women in R&D jobs resulted in radical innovation. It appears women score far higher than men in championing change. If you seek growth from affordable products and services for low-income groups, women often have the best ideas.
Five, break barriers to allow progress. Cultural and structural issues must be fixed. Unconscious biases and discrimination are rampant even in highly-esteemed organizations. Establish fair and transparent human resource policies.
Six, get involved in local communities to engage them. As Michael Porter said, it is not possible for businesses to sustain long-term shareholder value without ensuring the welfare of the communities they exist in. It is in the best interest of enterprises to engage with local communities to understand and work towards lowering cultural and other barriers in society. It will also help connect with potential customers, employees and special interest groups driving the gender-equity agenda and achieve better diversity.
