Two cheers: On India’s Sustainable Development Goals index score

India betters score in the latest SDG Index, but methodological (प्रणाली संबंधी) tinkering (फेरबदल, इधर-उधर करना) is cause for concern

India’s push (धक्का दें, प्रयास, अभियान, पहल) in the right direction in achieving Sustainable (सतत, चिरस्थायी, दीर्घकालिक) Development Goals (SDGs) related to clean energy (स्वच्छ ऊर्जा), urban development and health has helped it improve its overall SDG score from 60 in 2019 to 66 in 2021, according to NITI Aayog’s SDG India Index (सूची, तालिका) 2020-21. Besides (के अलावा, इसके अतिरिक्त) SDGs on eradication (नाश, तबाही, उन्मूलन) of poverty and hunger (भूख, भोजन की आवश्यकता; भुखमरी), measures (उपाय, कार्रवाई, कदम, प्रक्रिया) related to the availability of affordable, clean energy (स्वच्छ ऊर्जा) in particular (विशेष रूप से, ख़ासकर), showed improvements across several States and Union Territories. The campaign to improve the access of households (गृहस्थी) to electricity and clean cooking fuel has been shown to be an important factor. While this is cause for cheer (खुशी का कारण, हंसमुख होने का कारण), the Index reveals that there has been a major decline in the areas of industry, innovation and infrastructure (the basic physical or organisational structure for something (to function properly)) besides decent work and economic growth, again made worse by the lockdowns imposed by the governments seeking (try, aim, attempt) to tackle the COVID-19 pandemic. But the stark differences (dissimilarity, contrast, deviation, unevenness, variation) between the southern and western States on the one hand and the north-central and eastern States on the other in their performance on the SDGs, point to (indicate, suggest, denote) persisting (continuing, prolonged, persistent, unrelenting, unending, lingering) socio-economic and governance disparities (imbalance, inequality, unevenness, disproportion). These, if left unaddressed, will exacerbate (intensify, increase, heighten, aggravate, worsen, compound) federal challenges and outcomes, as seen in the public health challenges during the second wave across some of the worse-off (in a difficult situation; in a tight spot; less fortunate/wealthy; beleaguered, troubled, hard-pressed) States.

Notwithstanding the improvement in key indicators (measure, gauge, index, signal), the Index has curiously made some methodological changes that render (make, cause to be, cause to become) comparisons on some SDGs over previous years moot (debatable, doubtful, arguable, disputable, problematic). The SDG on inequality (Inequality is simply defined as “the state of not being equal, especially in status, rights, and opportunities; imbalance, unevenness, disproportion, disparity) shows an improvement over 2019, but the indicators used to measure the score have changed. The 2020-21 Index drops several economic indicators and gives greater weightage to social equality (fairness, justness, egalitarianism, equal rights/opportunities, non-discrimination) indicators such as representation of women and people from marginalised (treated as insignificant, treated as unimportant, neglected) communities in legislatures (local authority, administration, executive, local government) and local governance institutions, and crimes against SC/ST communities. By dropping the well-recognised Gini coefficient (a statistical measure of economic inequality in a population. The coefficient measures the dispersion of income or distribution of wealth among the members of a population) measure and the growth rate for household expenditure per capita among 40% of rural and urban populations (instead, only the percentage of population in the lowest two wealth quintiles is used), the SDG score on inequality seems to have missed out (fail to add/include something, omit; fail to utilize/take advantage of something) on capturing the impact of the pandemic on wealth inequality. This could be a significant miss (omission, slip, blunder, error, mistake) as a UN assessment of the impact of COVID-19 had said that the South Asian region may see rising inequality. Methodological issues on measuring other SDGs have been flagged (indicate, identify, point out) before, but the lack of adequate measurement of economic inequality seems to be a glaring (obvious, visible, apparent, flagrant, blatant) miss. Like in the first wave, the second wave, with more fatalities, has had similar outcomes on livelihoods (means of making a living with the basic necessities (food, water, shelter and clothing); means of support, subsistence, source of income) and jobs. While the better score for India in its endeavour (activity, pursuit; aim/effort) to achieve SDGs will bring some cheer, governments must work on addressing (tackle, deal with, attend to, try to sort out) pressing issues such as increased inequality and economic despair (hopelessness, depression, distress, pain).

World Environment day 2021

World Environment Day 2021
The World is celebrating World Environment Day today i.e. 5th June 2021. Every year a different country host an event on this day to celebrate the beautiful presence of mother nature and to raise awareness about the various human activities that are disrupting the harmonious balance of life around us.

“World Environment Day, it’s Time for Nature”

This quote sets the tone and defines the purpose behind celebrating the day. United Nations first celebrated World Environment Day in 1974. Since then, the UN celebrates this day on 5th June of every year to raise awareness about the environmental issue world is facing today such as human overpopulation, global warming, marine pollution, wildlife crimes, desertification etc. 

➤History of the World Environment Day

World Environment Day was established by the UN General Assembly in 1972 on the first day of the Stockholm Conference on the Human Environment, resulting from discussions on the integration of human interactions and the environment. Two years later, in 1974 the first World Environment Day was held with the theme “Only One Earth”. Even though the celebration has been held annually since 1974, in 1987 the idea for rotating the centre of these activities through selecting different host countries began.

Note: India hosted World Environment Day on 5th June 2018. The theme of the day was “Beat the Plastic Pollution.” 

➤World Environment Day 2021

Every year a different country host this prestigious day. This year’s World Environment Day is being hosted by ‘Pakistan’ in partnership with the UN Environment Programme (UNEP). The event has become the platform for reaching out and engaging governments, NGOs, corporations, businesses, celebrities and citizens to focus their efforts on a pressing environmental issue. The theme for World Environment Day 2021 is “Ecosystem Restoration” and will see the launch of the UN Decade on Ecosystem Restoration. Ecosystem restoration can take many forms: Growing trees, greening cities, rewilding

What is Ecosystem restoration?

Ecosystem restoration means assisting in the recovery of ecosystems that have been degraded or destroyed, as well as conserving the ecosystems that are still intact. Healthier ecosystems, with richer biodiversity, yield greater benefits such as more fertile soils, bigger yields of timber and fish, and larger stores of greenhouse gases.

Restoration can happen in many ways – for example through actively planting or by removing pressures so that nature can recover on its own. It is not always possible – or desirable – to return an ecosystem to its original state. We still need farmland and infrastructure on land that was once forest, for instance, and ecosystems, like societies, need to adapt to a changing climate.

The Earth – Shape and Size

Shape of the Earth

Pythagoras (572-500 B.C.), a Greek philosopher and mathematician, was among the first to suggest that the Earth was shaped like a globe.

The Earth is not flat

1.    If the Earth were a flat disc, then the rising Sun would have been seen at all places at the same time. But this does not happen. Places in the east see the rising Sun earlier.

2.    When a ship approaches land, its funnel or mast is seen first and then the hull. If the Earth had been flat, the whole ship would have been seen at the same time.

The Earth is a sphere

1.    The Earth is rarely oriented in the same position during successive eclipses but it always casts a circular shadow, thus proving that the Earth is a sphere. A sphere is the only solid body that will always cast a circular shadow.

2.    At the North Pole, the Pole Star can always be observed at 90 degrees in the sky, since the star lies in the line with the axis of the Earth.

3.    As one travels southwards, the angle of Pole Star decreases.

4.    At the Equator the angle becomes zero degree.

5.    This observation proves that the path of travel is an arc of a circle.

6.    The Sun, Moon and all the heavenly bodies appear to be spherical when viewed from different positions. It seems logical to conclude that the Earth is no exception.

7.    The photographs of the Earth taken from the space prove beyond any doubt that the Earth is a sphere.

The Earth as an Oblate Spheroid

1.    Refined measurements of the Earth have proved that the true form of the Earth resembles a sphere that has been compressed at the poles and made to bulge at the Equator. This form is known as an oblate spheroid.

2.    The various factors which make the earth suitable for

3.    life to evolve and survive are

4.    The earth has all the essential elements like carbon (in the form of C02), hydrogen (H2), nitrogen (N2) and oxygen (02) which act as building blocks for the origin of life.

5.    The earth is neither too hot nor too cold. It has the right temperature range for carrying out the life-sustaining chemical reactions.

6.    The earth has a lot of water in the form of lakes, rivers and oceans for the growth and survival of life.

7.    The earth has enough oxygen gas in its atmosphere for the survival of living beings through breathing.

8.    The earth has a protective blanket of ozone layer high up in its atmosphere to save life from harmful ultraviolet radiations coming from the sun.


Australia with New Zealand, Tasmania, New Guinea and the Pacific Islands (Micronesian, Melanesian and Polynesian Islands) is called Australasia by some geographers while some others call it “Oceania”, which includes proximate islands (Caribbean countries etc.).

Oceans on The Earth

There are four oceans. In order of their size, they are : Pacific Ocean, Atlantic Ocean, Indian Ocean and Arctic Ocean.

Pacific Ocean

1.    The explorer Ferdinand Magellan, who circumnavigated the Earth, named the ocean “Pacific” meaning calm or peaceful.

2.    The Pacific Ocean (Area : 166,240,000 sq. km.) is the largest ocean of the world.

3.    It is the deepest ocean with an average depth of 4,200 m.

4.    The Mariana Trench is the world’s deepest trench with a depth of 11,033 metres (36,201 feet).

5.    Most of the islands of this ocean are of volcanic or coral origin.

Atlantic Ocean

1.    The Atlantic Ocean (Area : 86,560,000 sq. km.) is the second largest ocean in the world

2.    Its name is derived from Atlas, a Titan (giant) in Greek mythology.

3.    The Atlantic Ocean has the longest coastline.

4.    The Atlantic Ocean is the busiest ocean for trade and commerce since its shipping routes connect the two most industrialized regions, namely Western Europe and N.E. United States of America.

5.    The Atlantic Ocean was formed millions of years ago when a rift opened up in the Gondwanaland and the continents of South America and Africa separated. The separation continues even today and the Atlantic Ocean is still widening.

6.    The continental islands of Newfoundland and British Isles are the major ones.

7.    Volcanic islands are fewer and they include those of Cuba, Jamaica and Puerto Rico. Iceland is the largest island of volcanic origin.

Indian Ocean

1.    The Indian Ocean (Area : 73,430,000 sq. km.) is the only ocean named after a country.

2.    The Indian Ocean is deeper than the Atlantic Ocean.

3.    It contains numerous continental islands, Madagascar and Sri Lanka are being the largest ones.

4.    Some of the islands of volcanic origin are those of Mauritius, Andaman and Nicobar, Seychelles, Maldives and Lakshadweep are of coral origin.

South Indian Ocean

1.    Warm currents : 1. South Equatorial 2. Mozambique 3. Madagascar 4. Agulhas.

2.    Cool Currents : 1. Antarctic drift 2. West Australian currents.

Arctic Ocean

1.    The Arctic Ocean (Area : 13,230,000 sq. km.) is the smallest of all the oceans.

2.    It lies within the Arctic Circle, hence the name Arctic Ocean.

3.    The North Pole lies in the middle of the Arctic Ocean.

4.    Most of the parts of Arctic Ocean remains frozen with thick ice for most of the days every year.

5.    It is the shallowest of all oceans, with an average depth of 1,500 m.

6.    It has the least salinity of all the oceans. It has a salinity of 20 unit per thousand.

Ocean Currents

1.    The flow of a large amount of water in a definite direction with a great intensity is known as Ocean Current.

2.    Ocean Currents are of two types-Hot and Cold.

Hot Currents

1.    The currents flowing from tropical zones of lower latitudes to higher temperate and sub polar zones are known as hot water currents.

Cold Currents

1.    The currents flowing from higher latitudes to lower latitudes are known as cold water currents.
2.    The only exception to the conduction of ocean currents is found in the Indian Ocean. The flow of currents changes here with a change in the direction of the Monsoon Winds. The hot currents flow towards cooler oceans and the cold currents flow towards the warmer oceans.
