QUICK REVISION BOOKLET
Virtual Digital Assets
As per the Finance Bill, the term ‘virtual digital assets’ includes both cryptocurrencies and NFTs.
A cryptocurrency, by whatever name called, would be considered a virtual digital asset, taxable under the Income Tax Act, 1961 if it meets the following criteria:
- It’s in the form of information, code, numbers, or tokens;
- It’s generated through cryptographic means or otherwise;
- It acts as a digital representation of value;
- It has some inherent value; and
- It allows for the storage and transfer of its units or tokens.
Government issued digital currencies, both Indian and foreign, have been specifically excluded from the scope of virtual digital assets.
Digital currency term applicable legally in India only when the currency is issued by a central bank.
Non-Fungible Token (NFT)
Non-fungible tokens (NFTs) are cryptographic assets on a blockchain with unique identification codes and metadata that distinguish them from each other. Unlike cryptocurrencies, they cannot be traded or exchanged at equivalency. This differs from fungible tokens like cryptocurrencies, which are identical to each other and, therefore, can serve as a medium for commercial transactions.
- NFTs can represent real-world items like artwork and real estate.
Meaning of Fungible
Like physical money, cryptocurrencies are fungible, meaning that they can be traded or exchanged, one for another. For example, one bitcoin is always equal in value to another bitcoin. Similarly, a single unit of ether is always equal to another unit. This fungibility characteristic makes cryptocurrencies suitable as a secure medium of transaction in the digital economy.
NFTs shift the crypto paradigm by making each token unique and irreplaceable, thereby making it impossible for one non-fungible token to be equal to another.
Article 351- Promotion of Hindi
Article 351 of the Constitution provides that it shall be the duty of the Union to promote the spread of the Hindi language to develop it so that it may serve as a medium of expression for all the elements of the composite culture of India and to secure its enrichment by assimilating without interfering with its genius, the forms, style and expressions used in Hindustani and in the other languages of India specified in the Eighth Schedule, and by drawing, wherever necessary or desirable, for its vocabulary, primarily, on Sanskrit and secondarily on other languages.
Nano Urea Liquid (NUL)
- NUL contains nano-scale nitrogen particles which have more surface area and number of particles making it more impactful.
- India has become the first country globally to start commercial production of NUL.
- Introduced by IFFCO.
Significance
- Reduces the requirement of conventional Urea by 50% or more.
- Improves Soil, Air & Water quality.
- Cheaper than conventional urea.
- Conventional urea is effective 30-40% in delivering nitrogen to plants, while the effectiveness of the Nano Urea Liquid is 80%.
India is dependent on imports to meet its urea requirements.
IVF
Important because of Surrogacy and Assisted Reproductive Technologies legislations passed recently
In vitro fertilization (IVF) is a complex series of procedures used to help with fertility or prevent genetic problems and assist with the conception of a child.
During IVF, mature eggs are collected (retrieved) from ovaries and fertilized by sperm in a lab. Then the fertilized egg (embryo) or eggs (embryos) are transferred to a uterus. One full cycle of IVF takes about three weeks.
IVF is the most effective form of assisted reproductive technology.
Various types of ART to solve infertility complications are :
- In Vitro Fertilization (IVF)
- GIFT- Gamete Intrafallopian Transfer
- ZIFT- Zygote Intrafallopian Transfer
- Intracytoplasmic sperm injection (ICSI)
- Intrauterine Insemination (IUI)
- Surrogacy
- Donor Eggs

System of Rice Intensification
(Already asked in UPSC Prelims)
The System of Rice Intensification, known as SRI — is an agro-ecological methodology for increasing the productivity of irrigated rice by changing the management of plants, soil, water and nutrients. SRI originated in Madagascar in the 1980s and is based on the cropping principles of significantly reducing plant population, improving soil conditions and irrigation methods for root and plant development, and improving plant establishment methods.
Carbon Farming
Carbon farming is a name for a variety of agricultural methods aimed at sequestering atmospheric carbon into the soil. Increasing the carbon content of soil can aid plant growth, increase soil organic matter (improving agricultural yield), improve soil water retention capacity,and reduce fertilizer use(and the accompanying emissions of greenhouse gas nitrous oxide (N2O).
Permaculture
Asked in Prelims earlier
Permaculture is a set of design principles centred around whole systems thinking simulating or directly utilizing the patterns and resilient features observed in natural ecosystems. It uses these principles in a growing number of fields from regenerative agriculture, rewilding, community, and organizational design and development.
Carbon Sequestration
Asked in Prelims earlier
Carbon sequestration or carbon dioxide removal (CDR) is the long-term removal, capture or sequestration of carbon dioxide from the atmosphere to slow or reverse atmospheric CO2 pollution and to mitigate or reverse global warming.
Geological Sequestration
Geological sequestration refers to the storage of CO2 underground in depleted oil and gas reservoirs, saline formations, or deep, un-minable coal beds.
Biochar
Asked in Prelims 2020
It is charcoal used as a soil amendment for both carbon sequestration and soil health benefits. Biochar is a stable solid, rich in carbon, and can endure in soil for thousands of years.Like most charcoal, biochar is made from biomass via pyrolysis.
Ocean Fertlisation
Ocean fertilization or ocean nourishment is a type of climate engineering based on the purposeful introduction of nutrients to the upper oceanto increase marine food production and to remove carbon dioxide from the atmosphere. A number of techniques, including fertilization by iron, urea and phosphorus have been proposed.
Ocean iron fertilization is an example of such a geoengineering technique. Iron fertilization attempts to encourage phytoplankton growth, which removes carbon from the atmosphere for at least a period of time.
Biosequestration
Biosequestration is the capture and storage of the atmospheric greenhouse gas carbon dioxide by continual or enhanced biological processes.
Ocean Acidification
Asked in Prelims earlier
Ocean acidification is the ongoing decrease in the pH of the Earth’s oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere. Seawater is slightly basic (meaning pH > 7), and ocean acidification involves a shift towards pH-neutral conditions rather than a transition to acidic conditions (pH < 7).
Net Metering
(Asked in Prelims earlier)
Net metering (or net energy metering, NEM) is an electricity billing mechanism that allows consumers who generate some or all of their own electricity to use that electricity anytime, instead of when it is generated. This is particularly important with renewable energy sources like wind and solar, which are non-dispatchable (when not coupled to storage).
Carbon Neutrality
Carbon neutrality, or having a net zero carbon footprint, refers to achieving net zero carbon dioxide emissions by balancing carbon emissions with carbon removal (often through carbon offsetting) or simply eliminating carbon emissions altogether (the transition to the “post-carbon economy”).
Carbon-neutral fuel is energy fuel or energy systems which have no net greenhouse gas emissions or carbon footprint. One class is synthetic fuel (including methane, gasoline, diesel fuel, jet fuel or ammonia) produced from renewable, sustainable or nuclear energy used to hydrogenate carbon dioxide directly captured from the air (DAC), recycled from power plant flue exhaust gas or derived from carbonic acid in seawater.
Climate Engineering Terminology
Solar geoengineering is a term used to describe a group of hypothetical technologies that could, in theory, counteract temperature rise by reflecting more sunlight away from the Earth’s surface.
Ocean afforestation – is a proposal for farming seaweed for carbon removal. After harvesting the seaweed decomposes into biogas, (60% methane and 40% carbon dioxide) in an anaerobic digester.
Stratospheric Aerosol injection
It could cool the planet in a similar way to a large volcanic eruption. When a volcano erupts, it sends an ash cloud high into the atmosphere. The sulphur dioxide released in the plume combines with water to form sulfuric acid aerosols, which are able to reflect incoming sunlight.Researchers have proposed that artificially introducing aerosols into the atmosphere – via a plane or a high-altitude balloon – could have a similar cooling effect.
Marine cloud brightening
In theory, this could involve using ships to spray saltwater into the clouds above the sea.Once airborne, the salt particles would act as “cloud condensation nuclei”, meaning they would facilitate the condensation of water vapour into liquid.
High-albedo crops and buildings
Idea of increasing the albedo of buildings in order to reflect more sunlight. Put simply, this would involve making rooftops and walls brighter – by painting them white, for example.
Ocean mirror
In theory, this would involve using a fleet of sea vessels to churn up millions of tiny microbubbles on the ocean surface.
Cirrus Cloud thinning
Asked in previous year Prelims Exam.
In theory, aerial vehicles such as drones could be used to deliver and then inject solid aerosol particles, such as desert dust or pollen, into cirrus clouds. Seeding the clouds in this way would cause them to dissipate more quickly, lessening their overall warming effect.
Space Sunshades
It involves sending a giant mirror – or fleet of mirrors – into orbit in order to reflect away more sunlight from the Earth.

Nanotechnology
- Nanotechnology is science, engineering, and technology conducted at the nanoscale, which is about 1 to 100 nanometers.
Properties of materials can be different on a nanoscale for two main reasons.
- First, nanomaterials have, relatively, a larger surface area than the same mass of material produced in a larger form.
- Second, below 50 nm, the laws of classical physics give way to quantum effects, provoking optical, electrical and magnetic behaviors different from those of the same material at a larger scale. – These effects can give materials very useful physical properties such as exceptional electrical conduction or resistance, or a high capacity for storing or transferring heat, and can even modify biological properties.
