5. Global Hunger Index
India ranks 111 out of a total of 125 countries in the Global Hunger Index (GHI) 2023.
About Global Hunger Index:
- It is a tool for comprehensively measuring and tracking hunger at global, regional, and national levels.
- It is prepared jointly by Irish aid agency Concern Worldwide and German organisation Welt Hunger Hilfe.
How it is calculated?
- GHI scores are based on the values of four component indicators
- Undernourishment: (the share of the population whose caloric intake is insufficient)
- Child stunting: (the share of children under the age of five who have low height for their age)
- Child wasting: ( the share of children under the age of five who have low weight for their height)
- Child mortality: (the share of children who die before their fifth birthday)
- The GHI score is calculated on a 100-point scale reflecting the severity of hunger, where zero is the best score (no hunger) and 100 is the worst.
Key findings of GHI-2023
- India’s ranking is based on a Global Hunger Index score of 28.7 on a 100-point scale.
- This categorises India’s severity of hunger as “serious”.
- The 2023 GHI score for the world is 18.3, which is considered moderate.
- Latin American and the Caribbean is the only region in the world whose GHI scores have worsened between 2015 and 2023.
- South Asia and Africa South of the Sahara are the world regions with the highest hunger levels, with GHI scores of 27.0 each.
6. Holodomor
The Parliamentary Assembly of the Council of Europe recently voted to recognize ‘Holodomor’ as a "genocide."
About Holodomor:
- It is a man-made famine that occurred in the Soviet republic of Ukraine from 1932 to 1933, peaking in the late spring of 1933.
- It left an estimated 3.9 million people dead.
- The primary victims of the Holodomor (literally "death inflicted by starvation") were rural farmers and villagers, who made up roughly 80 percent of Ukraine's population in the 1930s.
- It was part of a broader Soviet famine (1931–34) that also caused mass starvation in the grain-growing regions of Soviet Russia and Kazakhstan.
- In 2006, by the Law of Ukraine “On the Holodomor of 1932-1933 in Ukraine”, the Holodomor was recognized as genocide of the Ukrainian nation.
- Causes:
- The origins of the famine lay in the decision by Soviet leader Joseph Stalin to collectivize agriculture in 1929.
- Teams of Communist Party agitators forced peasants to relinquish their land, personal property, and sometimes housing to collective farms, and they deported so-called kulaks—wealthier peasants—as well as any peasants who resisted collectivization altogether.
- Collectivization led to a drop in production, the disorganization of the rural economy, and food shortages.
- It also sparked a series of peasant rebellions, including armed uprisings, in some parts of Ukraine.
- In 1932, the Communist Party set impossibly high quotas for the amount of grain Ukrainian villages were required to contribute to the Soviet state.
- When the villages were not able to meet the quotas, authorities intensified the requisition campaign, confiscating even the seed set aside for planting.
- Farms, villages, and whole towns in Ukraine were placed on blacklists and prevented from receiving food.
- Peasants were forbidden to leave the Ukrainian republic in search of food.
- In some cases, soldiers were posted in watchtowers to prevent people from taking any of the harvest. Millions starved as the USSR sold crops from Ukraine abroad.
7. Aerosols
A new analysis by the Indian Space Research Organisation’s (ISRO) Physical Research Laboratory has shown that the Hindu Kush-Himalaya-Tibetan Plateau region has been witnessing an alarming increase in aerosol levels.
About Aerosols:
- They are tiny solid or liquid particles suspended in air or as a gas.
- Aerosols can be natural, such as fog or gas from volcanic eruptions, or artificial, such as smoke from burning fossil fuels.
- Aerosol particles are either emitted directly to the atmosphere (primary aerosols) or produced in the atmosphere from precursor gases (secondary aerosols).
- Aerosol particles are tiny, but numerous, and often comprise of a number of inorganic and organic substances.
- True aerosol particles range in diameter from a few millimicrometres to about 1 micrometre (equal to 10-4 cm).
- Particles with a diameter of less than 0.1 micrometre are sometimes referred to as Aitken nuclei.
- Visible forms of atmospheric aerosol plumes include smoke, smog, haze and dust.
- How do aerosols affect climate?
- Aerosol particles, such as dust, play an important role in the precipitation process, providing the nuclei upon which condensation and freezing take place.
- They affect climate by reflecting or absorbing incoming solar radiation and enhancing the brightness, and thus reflectivity, of clouds.
- Although absorption, like reflection, tends to reduce sunlight at the ground level, the enhanced atmospheric heating eventually warms up the surface, and counteracts the cooling caused by reflection.
- They also participate in chemical processes and influence the electrical properties of the atmosphere.
8. Gunji Village

- Gunji village is administered by Sarpanch (Head of Village) who is elected representative of the village.
- The village is on the traditional Indian/Nepalese route to Kailas–Manasarovar.
- To visit Gunji, one has to obtain an Inner Line permit.
What is an Inner line permit (ILP)?
- ILP is an official travel document issued by the Government of India to allow inward travel of an Indian citizen into a protected area for a limited period.
- It is obligatory for Indian citizens from outside those states to obtain a permit for entering the protected state.
- The document is an effort by the government to regulate movement to certain areas located near the international border of India.
- This is an offshoot of the Bengal Eastern Frontier Regulations, 1873, which protected the Crown’s interest in the tea, oil and elephant trade by prohibiting “British subjects” from entering into these “Protected Areas”.
- The word “British subjects” was replaced by Citizen of India in 1950.
- There are different kinds of ILPs, one for tourists and others for people who intend to stay for long-term periods, often for employment purposes.
