Prelims level: Eat Out to Help Out Scheme
Mains level: NA
Since the lockdown began in India, different bodies representing the country’s hospitality sector have repeatedly asked the government for financial assistance to help tide over the crisis. UK’s popular Eat Out to Help Out (EOHO) Scheme can be an example of the kind of intervention in India.
Note: The ‘Eat Out to Help Out’ Scheme recently seen in news is related to Hospitality. One may get confused over Poverty and Hunger.
What is the EOHO Scheme?
- The EOHO Scheme is an economic recovery measure by the UK government to support hospitality businesses as they reopen after the lockdown.
- The scheme was announced as part of the Plans for Jobs summer economic update.
- Under the EOHO Scheme, the government would subsidise meals (food and non-alcoholic drinks only) at restaurants by 50 per cent.
- There is no minimum spending and no limit on the number of times customers can avail the offer, since the whole point of the scheme is to encourage a return to dining in restaurants.
Why was this scheme deemed necessary?
- All over the world, the food services sector is one of the worst affected by the pandemic.
- The top two concerns were customers avoiding restaurants for fear of contracting the virus and customers having less disposable income for dining out.
- Instead of delivering a financial package to operators, it makes eating out more affordable for consumers directly and helps restore demand.
- Restoring consumer demand is being seen as crucial to the UK’s economic recovery.
Can India benefit from such a scheme?
- The main problem confronting the restaurant industry, following Unlock 1.0 in June, has been consumer fear, even as the government has remained silent about specific recovery packages aimed at the hospitality industry.
- The government needs to work on the demand side.

(a) Jatropha
(b) Maize
(c) Pongamia
(d) Sunflower
What is Ethanol Blended Petrol (EBP) Program?
- Ethanol Blended Petrol (EBP) programme was launched in January 2003 for the supply of 5% ethanol blended petrol.
- The programme sought to promote the use of alternative and environment-friendly fuels and to reduce import dependency for energy requirements.
- OMCs are advised to continue according to the priority of ethanol from 1) sugarcane juice/sugar/sugar syrup, 2) B-heavy molasses 3) C-heavy molasses and 4) damaged food grains/other sources.
Bio-ethanol blend in India
- 1G and 2G bioethanol plants are set to play a key role in making bio-ethanol available for blending but face challenges in attracting investments from the private sector.
- 1G bioethanol plants utilise sugarcane juice and molasses, byproducts in the production of sugar, as raw material, while 2G plants utilise surplus biomass and agricultural waste to produce bioethanol.
- Currently, domestic production of bioethanol is not sufficient to meet the demand for bio-ethanol for blending with petrol at Indian Oil Marketing Companies (OMCs).
- Sugar mills, which are the key domestic suppliers of bio-ethanol to OMCs, were only able to supply 1.9 billion litres of bio-ethanol to OMCs equating to 57.6 per cent of the total demand of 3.3 billion litres.
Hurdles in meeting the demand
- Lack of infrastructure: Many sugar mills are best placed to produce bioethanol do not have the financial stability to invest in biofuel plants. There are also concerns among investors on the uncertainty over the price of bio-ethanol in the future.
- Lack of raw materials: Presently there is no mechanism for depots where farmers could drop their agricultural waste. The central government should fix a price for agricultural waste to make investments in 2G bioethanol production an attractive proposition.
- Rigid pricing mechanism: Sugars mills have to pay high prices for sugarcane set by the government even when there have been supplying gluts. The prices of both sugarcane and bio-ethanol are set by the central government.
Way ahead
- The government should provide greater visibility on the price of bioethanol that sugar mills can expect by announcing a mechanism by which the price of bio-ethanol would be decided.
- 2G bioethanol not only provided a clean source of energy but also help provide greater income to farmers and prevent them from having to burn agricultural waste which can be a major source of air pollution.

(b) Inter-Tropical Convergence Zone seldom occurs
(c) Coriolis force is too weak
(d) Absence of land in those regions
What is a Tornado?
- A tornado is a rapidly rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud.
- The windstorm is often referred to as a twister, whirlwind or cyclone winds blow counterclockwise in the Northern Hemisphere and clockwise in the Southern.
- Tornadoes come in many shapes and sizes, and they are often visible in the form of a condensation funnel originating from the base of a cumulonimbus cloud, with a cloud of rotating debris and dust beneath it.
- It is generally accompanied by extreme weather such as heavy downpours, hail storms, and lightning.
Who was Babu ChunderSikur Chatterjee?
- Chatterjee was an Indian scientist employed with the Surveyor General of India during the British colonial era.
- He was likely the first person to scientifically document a tornado’s path in 1865, a study from the Indian Institute of Tropical Meteorology (IITM), Pune, has claimed.
- Chatterjee had published his findings in a journal named Proceedings of the Asiatic Society of Bengal, in a paper titled ‘Note on a whirlwind at Pundooah’, near Hooghly.
- The paper described a tornado’s dynamics in meticulous detail and was accompanied by a sketch that mathematically depicted its scale, track and rotation.
His work
- Chatterjee quantitatively mapped the entire trail of á tornado’s destruction.
- He benefited from the rare opportunity to observe a tornado passing through a railway track where there were conveniently placed markers at predefined locations.
- This enabled him to observe and make clear measurements of the tornado’s direction, dynamics and path.

Prelims level: Ceres and other dwarf planets
Mains level: Not Much
The dwarf planet Ceres, which lies in the asteroid belt between Mars and Jupiter now, has the status of an “ocean world”.
Note various dwarf planets and the criteria making a planet dwarf, as mentioned in the B2b section.
Ceres exploration
- The dwarf planet was first spotted by Giuseppe Piazzi in 1801, who assumed that Ceres was the missing planet between Mars and Jupiter.
- It was classified as a dwarf planet in 2006 and is the first dwarf planet to be orbited by a spacecraft.
- In 2015, NASA’s Dawn reached it to study its surface, composition and history.
What does it mean to be an “ocean world”?
- With a crust that mixes ice, salts, rock-forming minerals and other materials, Ceres looks to be a remnant “ocean world,” wearing the chemistry of its Old Ocean and records of the interaction on its surface.
- The observations from Dawn suggest the presence of briny liquid (saltwater) water under Ceres’s surface.
- Scientists have determined that Ceres has a brine reservoir located about 40 km deep and which is hundreds of miles wide, making the dwarf planet, “water-rich”.
Why do researchers study Ceres?
- Scientists are interested in this dwarf planet because it hosts the possibility of having water, something that many other planets do not have.
- Therefore, scientists look for signs of life on Ceres, a possibility that has also maintained scientists’ interest in the planet Mars, whose atmosphere was once warm enough to allow water to flow through it.
- Another reason why scientists are interested in that studying it can give insights about the formation of the Solar System since it is considered to be a fossil from that time.
Back2Basics: Dwarf Planets
- As of today, there are officially five dwarf planets in our Solar System.
- The most famous is Pluto, downgraded from the status of a planet in 2006.
- The other four, in order of size, are Eris, Makemake, Haumea and Ceres. The sixth claimant for a dwarf planet is Hygiea, which so far has been taken to be an asteroid.
- These four criteria are – that the body orbits around the Sun, it is not a moon, has not cleared the neighbourhood around its orbit and has enough mass for its gravity to pull it into a roughly spherical shape.

Mains level: Not Much
The Gujarat government recently awarded the contract for a the Bhadbhut project in Bharuch, Gujarat. It has faced protests from local fishermen for its likely impact on fishing patterns, notably those of hilsa.
Make a note of major dams in India along with the rivers, terrain, major wildlife sanctuaries and national parks incident to these rivers.
What is the Bhadbhut Project?
- It is planned to be a 1.7-km causeway-cum-weir barrage with 90 gates, across the river Narmada, 5 km from Bhadbhut village, and 25 km from the mouth of the river, where it flows into the Gulf of Khambhat.
- The barrage will stop most of the excess water flowing out of the Sardar Sarovar Dam from reaching the sea and thus create a “sweet water lake” of 600 mcm (million cubic metres) on the river.
- The barrage will also have a six-lane road that will connect the left and right banks of the river and provide shorten the land distance between two large industrial estates in Surat and Bharuch.
- The project also aims to prevent flooding in years when rainfall is higher than normal.
- Embankments 22 km long will be made and will extend upstream towards Bharuch, from either side of the river.
- The project is part of the larger Kalpasar Project, which entails the construction of a 30-km dam across the Gulf of Khambhat between Bharuch and Bhavnagar districts.
- The reservoir is meant to tap the waters of the Narmada, Mahisagar and Sabarmati.
Why are fishermen upset?
- The barrage is expected to interfere with the migration and breeding cycle of hilsa.
- A marine fish, hilsa migrate upstream and arrives in the brackish water of the Narmada estuary near Bharuch for spawning usually during the monsoon months of July and August, and continue doing so till November.
- Once the barrage is built, it is expected to block its natural entry.
About Hilsa Fish
IUCN status: Least Concerned
- The Hilsa is a species of fish related to the herring, in the family Clupeidae.
- It is a very popular and sought-after food fish in the Indian Subcontinent.
- Though it’s a saltwater fish, it migrates to sweet waters.
- It is the national fish of Bangladesh and state symbol in the Indian states of West Bengal and Tripura.
- The fish contributes about 12% of the total fish production and about 1.15% of GDP in Bangladesh.

- It is one of the hottest places on Earth, along with deserts in the Middle East and the Sahara.
- The valley is extremely dry because it lies in the rain shadow of four major mountain ranges (including the Sierra Nevada and the Panamint Range).
- Moisture moving inland from the Pacific Ocean must pass eastward over the mountains to reach Death Valley; as air masses are forced upward by each range, they cool and moisture condenses, to fall as rain or snow on the western slopes.
- When the air masses reach Death Valley, most of the moisture has already been lost and there is little left to fall as precipitation.
Key factors leading to its high temperature
- Solar heating: The valley’s surface (consisting of soil, rocks, sand, etc.) undergoes intense solar heating because the air is clear and dry, and the land is dark and sparsely vegetated. This is especially noticeable in summer when the sun is nearly directly overhead.
- Trapping of warm air: Warm air naturally rises and cools; in Death Valley, this air is subject to continual reheating as it is trapped by high, steep valley walls and recycled back to the valley floor.
- Migration of warm air from other areas (advection): Warm desert regions adjacent to Death Valley, especially to the south and east, often heat air before it arrives in Death Valley.
- Warm mountain winds: As winds are forced up and over mountains (e.g., the numerous ranges west of Death Valley), the winds can be warmed in several ways. The resulting dry, warm winds are known as foehn winds.
