About Kalasa-Bhanduri Project:
- The project involves the construction of dams and a canal system to divert water from the Mahadayi River, located in Goa, to the Malaprabha River (a tributary of the Krishna River) basin in Karnataka.
- The main goal of the project is to meet the drinking water needs of the districts of Belagavi, Dharwad, Bagalkot, and Gadag in Karnataka.
- Though the project was first proposed in the early 1980s, it has remained on paper owing to a dispute between Karnataka, Goa, and Maharashtra.
- As per plans, barrages are to be built against Kalasa and Bhanduri streams— tributaries of Mahadayi — and water diverted towards Karnataka’s parched districts.
Key facts about Mahadayi River:
- Origin: It rises in the Western Ghats from the Bhimgad Wildlife Sanctuary in Khanapur taluk of Karnataka’s Belagavi district.
- The river travels35 km in Karnataka, and 82 km in Goa before joining the Arabian Sea at Panaji (North Goa).
- Also called Mandovi in Goa, Mahadayi is a rain-fed river that is shared between Karnataka and Goa for their water needs.
- The Salim Ali Bird Sanctuary is located on the island of Chorao in the Mandovi River.
- Major Tributaries: Kalasa Nala, Bhanduri Nala, Surla Nala, Haltar Nala, Poti Nala, Mahadayi Nala, Pansheer Nala, Bail Nala and Andher Nala.
About Supreme Court Collegium:
- It is a system under which appointments and transfers of judges are decided by a forum of the Chief Justice of India and the four senior-most judges of the Supreme Court (SC).
- It is not mentioned in the Indian Constitution.
- What does the Constitution actually prescribe?
- Article 124deals with the appointment of SC judges. It says the appointment should be made by the President after consultation with such judges of the High Courts and the Supreme Court as the President may deem necessary. The CJI is to be consulted in all appointments, except his or her own.
- Article 217deals with the appointment of High Court judges. It says a judge should be appointed by the President after consultation with the CJI and the Governor of the state. The Chief Justice of the High Court concerned too should be consulted.
- Evolution of the Collegium System:
- Since the Constitution mandates consultation with the CJI is necessary for appointments to the judiciary, the collegium model evolved.
- It has its genesis in a series of three judgments that are now clubbed together as the Three Judges Cases.
- First Judges Case (1982):
- The SC held that "consultation" of judges does not mean concurrence.
- Hence, it gave primacy in the appointment of judges to the Executive.
- Second Judges Case (1993):
- The court reversed its earlier ruling by changing the meaning of "consultation" to concurrence.
- With this, the advice tendered by CJI became binding. However, the CJI would have to take into account the views of two of his senior most colleagues.
- Third Judges Case (1998):
- The court gave primacy to the opinion of the CJI in the matter of the appointment of Judges.
- However, the CJI must consult four senior-most judges of SC.
- Opinions of all members of the collegium should be in writing.
- In case of a difference of opinion, the majority view will prevail.
- Even if two judges in the collegium give an adverse opinion of a person for appointment as the SC judge, the CJI should not send the recommendation to the government.
- These three cases established that the collegium headed by the Chief Justice of India would have primacy in the appointment of judges to the higher judiciary.
- This collegium makes recommendations to the government for the appointment of judges to the SC and of Chief Justices of High Courts, and the transfers of HC judges.
- Executive role:
- Judges of the higher judiciary are thus appointed only through the collegium system, and the government has a role only after names have been decided by the collegiums.
- The government’s role is limited to getting an inquiry conducted by the Intelligence Bureau (IB) if a lawyer is to be elevated as a judge in a High Court or the Supreme Court.
- The government can also raise objections and seek clarifications regarding the collegium’s choices, but if the collegium reiterates the same names, the government is bound to appoint them.
About Adverse Possession:
- It is a legal concept that allows a person who has unlawfully occupied someone else’s land for a certain period of time to claim legal ownership of that land.
- The claimant must demonstrate that several criteria have been met before the court will allow their claim.
- If the adverse possession is successful after following certain requirements and conditions, there will be no requirement to compensate the owner for that property or receive their permission.
- Adverse possession is also known as squatter’s rights.
- It is a negative and consequential right that arises due to the negligence of the true owner.
- The rights and conditions for achieving adverse possession vary depending on the country.
- In India, adverse possession has been a part of the legal framework for a long time and is rooted in the idea that land must not be left vacant and instead be put to judicious use.
- The law of Adverse Possession in India is governed by the principle of The Limitation Law of 1963.
- The law on adverse possession provides that any person who has been in possession of private land for more than 12 years or government land for over 30 years is granted ownership rights to the property.
- To claim adverse possession, the occupier must prove that they have been in continuous, uninterrupted possession of the land for at least 12 years (in the case of private land) and that their possession was open, notorious, and hostile to the true owner.
- As per adverse possession under the limitation act, if, over a due course of time or period, an appeal is not made to revise any limitation, the current scenario of titles continues.
- Thus, if a property owner fails to make a claim on their property for 12 years and the same tenant continues to occupy the property for 12 years, the ownership rights to the property are transferred to the tenant.
- If one intends to establish adverse possession under the Limitation Act of 1963, the burden of proof will rest on them.
About Thames River:

About Halogens:
- Halogens are any of the six non-metallic elements that constitute Group 17 (Group VIIa) of the periodic table.
- The halogen elements are:
- fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).
- The word halogen means "salt-producing” because halogens react with metals to produce many important salts, of which sodium chloride—table salt, or halite—is best known.
- Properties:
- Halogens are so reactive that they do not occur as free elements in nature. They are the most reactive nonmetals.
- The halogen atoms carry seven valence electrons in their outermost electron shell.
- This accounts for their higher reactivity and tendency to gain one electron and form ionic bonds or share electrons with other elements to form covalent bonds.
- Among all the halogens, fluorine is the most reactive, and Iodine is the least reactive of all.
- In combined form, fluorine is the most abundant of the halogens in Earth’s crust.
- Halogens are the only group on the periodic table that has elements in the solid, liquid, and gas phases at room temperature.
- At normal temperature and pressure, chlorine and fluorine are gasses, bromine is a liquid, and iodine and astatine are solids.
- They are powerful oxidizing agents.
- They have very high electronegativities.
- Halogens have a tendency to form hydrogen halides, which are potent acids when they combine with hydrogen.
About Fund of Funds Scheme:
- The Fund of Funds for Startups (FFS) Scheme was approved and established in 2016 with a corpus of Rs 10,000 crore,
- Funding to startups: Under FFS, the Scheme does not directly invest in startups, instead provides capital to SEBI-registered AIFs, known as daughter funds, who in turn invest money in growing Indian startups through equity and equity-linked instruments.
- Small Industries Development Bank of India (SIDBI) has been given the mandate of operating this Fund through selection of suitable daughter funds and overseeing the disbursal of committed capital.
- AIFs supported under FFS are required to invest at least 2 times of the amount committed under FFS in startups.
Key facts about the Small Industries Development Bank of India (SIDBI)
- It was established under an Act of Parliament in 1990.
- It is the Principal Financial Institution engaged in the promotion, financing & development of the Micro, Small and Medium Enterprises(MSMEs) sector and the coordination of the functions of the various institutions engaged in similar activities.
- Objective: To offer loans (both direct and indirect) to MSMEs to help in addressing the development and financial gaps in the ecosystem of MSMEs.
- It helps MSMEs in acquiring the funds they require to grow the market, develop and commercialise their technologies and innovative products.
- It was made responsible for administering the Small Industries Development Fund and National Equity Fund.
About Aral Sea:
- It stands at the boundary between Kazakhstan to the north and Uzbekistan to the south.
- It was once a large saltwater lake of Central Asia and the world’s fourth largest body of inland water.
- The remnants of it nestle in the climatically inhospitable heart of Central Asia, to the east of the Caspian Sea.
- The Aral Sea depression was formed toward the end of the Neogene Period(which lasted from about 23 to 2.6 million years ago).
- It was made by waters from the Syr Darya and the Amu Darya rivers that were dependent on glacial melt.
- It drains Uzbekistan and portions of Kazakhstan, Tajikistan, Afghanistan, Turkmenistan, Iran, and Kyrgyzstan.
- Climate: The Aral Sea is located within the harsh climate region of Central Asia. The area experiences a desert-continental climate, characterised by hot summers, cold winters, and varying diurnal air temperature.
- Reason for its disappearance
- According to the space agency, in 1960 the Soviet Union undertook a major water diversion project where they diverted the Syr Darya and the Amu Darya rivers for irrigation projects.
- Though the project made the desert region surrounding the sea bloom, it had a devastating impact on the Aral Sea.
- The waterbody slowly started drying up and today it is on the verge of complete disappearance.
About Frozen smoke:
- The frozen smoke, technically known as aerogel, is an extraordinary material.
- It was originally developed in the 1930s.
- The name aerogel comes from the combination of the Greek word “aero”, meaning air, and “gel”, since aerogels are derived from gels.
- It is hailed as a miracle material.
- Properties
- Aerogel can claim a low density, high thermal resistivity and a highly porous structure.
- The texture of aerogel is similar to a fine, dry sponge, but feels much lighter
- In fact, aerogel holds the record as the lightest solid in the world.
- When pressed softly, aerogel will return to its original form, but when pressed harder, a dimple forms. Put aerogel under too much pressure, however, and it will shatter like glass into many tiny pieces.
- They are composed mostly of air and can be used to remove contaminants.
What is Formaldehyde?
- It is a common Volatile organic compound (VOC) and is emitted by household items including pressed wood products (such as MDF), wallpapers and paints, and some synthetic fabrics.
- For the most part, the levels of formaldehyde emitted by these items are low, but levels can build up over time.
- Formaldehyde can lead to serious health problems with prolonged exposure even at low concentrations.
About Dhokra Shilpkala:
- The word "Dhokra" is believed to be derived from the Dhokra Damar tribes, who are the traditional metal smiths of Central India.
- The origins of Dhokra Shilpkala can be traced back to the tribal communities residing in the regions of Chhattisgarh, Jharkhand, West Bengal, and Odisha, where it evolved as an integral part of their cultural and religious practices.
- Technique and Process: What sets Dhokra Shilpkala apart is its remarkable technique of metal casting, which involves using the lost wax casting method, also known as cire perdue.
- Artistry and Designs:
- Its design has rustic charm and the organic nature of its designs.
- Artisans draw inspiration from nature, mythology, and everyday life, incorporating motifs such as animals, birds, deities, and tribal symbols into their creations.
- From miniature figurines and jewellery to larger-than-life sculptures and functional objects, Dhokra Shilpkala encompasses a wide range of artistic expressions.
- Issues: The rapid pace of urbanisation, coupled with the rise of mechanised production techniques, has threatened the livelihoods of traditional artisans and endangered this ancient craft.
What is the Lost wax method?
- The process begins with the creation of a clay core, which serves as the base for the final metal sculpture.
- Artisans then coat this clay core with a layer of beeswax, meticulously sculpting the intricate designs and patterns by hand.
- Once the wax model is complete, it is covered with layers of clay, forming a mould around the wax pattern.
- The entire structure is then heated, allowing the wax to melt and drain out, leaving behind a cavity in the shape of the original sculpture.
- Molten metal, typically a combination of brass and bronze, is poured into this cavity, filling the space left by the melted wax.
- After cooling and solidifying, the clay mould is broken away, revealing the final metal casting.
