Bhojpatra Tree: Recently, the Prime Minister of India, in the 103rd edition of Mann ki Baat programme highlighted the business of 'bhojpatra calligraphy' by the women of Mana village near Badrinath. Found at a height of 3,000m or above, bhojpatra (Himalayan Birch) is a tree whose bark acts as paper on which text can be written. It is also known as Himalayan Birch and it is widely found in the Himalayas. It is a deciduous tree native to the Western Himalayas that grows at elevations of up to 4,500 metres It has a high freezing tolerance potential, allowing it to form a treeline in the Himalayan region. It is a long-lived species which can survive up to 400 years and the only angiosperm in the Himalaya which dominates an extensive area at sub - alpine altitudes. Distribution: It is widely distributed in the altitudinal range from 3100 - 3800 m in North-western Himalaya. It contributes to the preservation of the Himalayan ecosystem by reducing soil erosion and creating a bio-shield for the remaining forests and sub-alpine meadows below the treeline. The bark of this tree was used for centuries in our Country for writing lengthy scriptures. Sathyamangalam Tiger Reserve:  Location: It is located at the junction of the Eastern and the Western Ghats in the Nilgiri Biosphere Reserve, in Tamil Nadu.

India’s transport-sector emissions could increase 65% by 2030 and 197% by 2050, relative to 2020 levels. Road followed by rail transport is the main contributor to sector emissions. Need to Decarbonise Transport sector :- Globally, India is third most CO2 emitting sector. High dependence on fossil fuels of the sector leads to exploitation of fossil fuels. To meet nationally determined contributions (NDCs) targets of India i.e., reduce emissions intensity of its GDP by 45% by 2030 etc  Initiatives taken to Decarbonise Transport sector :- (1) Bharat Stage VI Emission Standards. (2) Forum for Decarbonizing Transport in India by NITI Aayog. (3) FAME India (part of National Electric Mobility Mission Plan) etc. Faster Adoption and Manufacturing of Electric Vehicle PLASTIC OVERSHOOT DAY 2023: THE EARTH'S PLASTIC CRISIS Context On July 28, 2023, the Earth experienced its first Plastic Overshoot Day, marking the point at which the amount of plastics exceeds the global waste management capacity. Global Plastic Pollution Trends Under current scenarios, global plastics pollution is projected to triple by 2040, despite pledges and increased waste management capacity. Key Contributors to Plastic Waste :- India is among the 12 countries, along with China, Brazil, Indonesia, Thailand, Russia, Mexico, the United States, Saudia Arabia, the Democratic Republic of Congo, Iran, and Kazakhstan, responsible for 52% of the world's mismanaged plastic waste. Plastic Consumption on Per-Person Basis:- Iceland tops the list of worst offenders in plastic consumption, with annual consumption of 128.9 kg per person. India's annual per-person plastic consumption is 5.3 kg, significantly lower than the global average of 20.9 kg. Plastic Overshoot Day is a wake-up call, shedding light on short-life plastics' environmental impact and their higher risk of leakage into the environment. Plastic pollution particularly impacts developing countries like India, which are categorized as 'waste sponges' due to their low plastic consumption but high plastic pollution levels.  Nagarjunsagar-Srisailam Tiger Reserve (NSTR). The National Tiger Conservation Authority (NTCA) recently raised concern that cattle grazing in the forest and illegal fishing in the backwaters of Srisailam and Nagarjunasagar dams are posing a big threat to tigers in Nagarjunsagar-Srisailam Tiger Reserve (NSTR). About Nagarjunsagar-Srisailam Tiger Reserve (NSTR): Location: It is located in the Nallamala hill ranges(an offshoot of the Eastern Ghats) of Andhra Pradesh. This is the largest tiger reserve in the country, spreading over an area of 5937 Sq. Km. It is named after two major dams in the area, Nagarjuna Sagar Dam and Srisailam Dam. Two wildlife Sanctuaries, namely Rajiv Gandhi Wildlife Sanctuary and Gundla Brahmeswaram Wildlife Sanctuary (GBM), constitute the Tiger Reserve. The river Krishna traverses through this Reserve Topography: It consists of plateaus, ridges, gorges, and deep valleys. Vegetation: Tropical dry deciduous forests with an undergrowth of bamboo and grass. The river Krishna has Muggers, otters, and Turtles. NOTE:- Nagarjunsagar-Srisailam Tiger Reserve is the largest tiger reserve in India, having the largest area under "Critical Tiger Habitat". The reserve spreads over five districts, Kurnool District, Prakasam District, Guntur District, Nalgonda District, and Mahbubnagar district. Critical Tiger habitat These are core areas of tiger reserves and are identified under the Wild Life Protection Act (WLPA), 1972 based on scientific evidence. Such areas are required to be kept as inviolate for the purpose of tiger conservation, without affecting the rights of the Scheduled Tribes or such other forest dwellers. The notification of CTH is done by the state government in consultation with the expert committee constituted for the purpose. Critical Wildlife Habitat Critical ‘wildlife’ habitats (CWLHs), on the other hand, are defined only in the Forest Rights Act, 2006. CWLHs are meant to be areas of national parks and wildlife sanctuaries that are required to be kept as inviolate for the purpose of wildlife conservation (not just tigers). Similar to CTH, the identification of CWLH is done based on scientific and objective criteria, but it mandatorily requires settlement of forest rights under FRA. Unlike CTHs, the notification of CWLHs can only be done with the consent of the Gram Sabhas and affected stakeholders. Q:) Among the following Tiger Reserves, which one has the largest area under “Critical Tiger Habitat”? (2020) (a)Corbett (b)Ranthambore (c)Nagarjunsagar-Srisailam (d)Sunderbans  Kuril Islands In Japan, conservative voices are hinting that Russian and Ukraine war could give Japan a chance to take control of disputed Kuril Islands. About Kuril Islands: These are a set of four islands situated between the Sea of Okhotsk and the Pacific Ocean near the north of Japan's northernmost prefecture, Hokkaido. Japan refers to them as Northern territories, Russia calls them the Kuril Islands and South Korea named them as Dokdo islands. These are part of the Pacific Ring of Fire belt and have over 100 volcanoes, of which 35 are said to be active volcanoes along with hot springs. Both Russia and Japan claim sovereignty over them though the islands have been under Russian control since the end of World War II. The Soviet Union had seized the islands at the end of World War II and by 1949 had expelled its Japanese residents. Tokyo claims that the disputed islands have been part of Japan since the early 19th century. UNESCO heritage danger list Context: Experts from UNESCO have recommended adding the Italian city of Venice to the list of world heritage sites in danger due to long-standing problems such as over-tourism and the effects of climate change. Kyiv and Lviv in Ukraine are also recommended to be put on the danger list this year. List of World Heritage in Danger: The United Nations Educational, Scientific and Cultural Organization (UNESCO) compiles the list of World Heritage in Danger.

Headquarter: Hyderabad.  Water neutrality in Indian industries The NITI Aayog, a government think-tank, has introduced a standard definition and approach for water neutrality in Indian industries. What is Water neutrality? Water neutrality is described as achieving a balance between total freshwater consumption, including both direct and indirect usage, and quantifiable water savings resulting from efficiency strategies. Explanation using an example: For instance, if a beverage company saves as much water through efficient production as it uses for making beverages and producing materials, it achieves water neutrality. If it saves more, it becomes water-positive; if it uses more, it’s not water-neutral. Steps to achieve water neutrality: Reduce water use by increasing water efficiency. Install water reuse systems such as rainwater harvesting or greywater recycling. Offset remaining water demand in the local region. Significance: NITI Aayog’s report estimates that following water neutrality standards could save 38.23 billion cubic meters of water over the next decade. National Water Mission’s Goal 4 (Increasing water use efficiency by 20%) includes the promotion of water-neutral and water-positive technologies. STUDY ON OCEAN COLOR CHANGES DUE TO CLIMATE CHANGE Context A study published in the journal Nature focused on the alteration of Earth's oceans' color over the past two decades. The possible connection between ocean color changes and human-induced climate change. Findings Over 56% of the Earth's oceans, exceeding the total land area on the planet, experienced shifts in color. The change in ocean color indicates that marine ecosystems are undergoing significant changes and may lead to potential imbalances in the future, affecting both ocean life and human dependence on marine resources. Reasons for Oceans Appearing Blue or Green:- Oceans appear blue or navy blue in most regions due to the absorption of longer wavelength colors like red, yellow, and green by water molecules, while shorter wavelength colors like blue and violet are reflected back. Certain parts of the oceans appear green due to the presence of phytoplankton on the upper surface of the water. Impact on Ocean Stratification The study suggests that ocean stratification, the natural separation of ocean water into horizontal layers by density, has increased due to climate change. Increased stratification hinders the mixing of water layers, affecting the ocean's ability to absorb carbon dioxide from the atmosphere and limiting proper oxygen mixing with cooler ocean waters below. Consequences for Marine Ecosystems :- Changes in plankton populations, particularly phytoplankton, can be observed in regions with higher concentrations of these organisms. This shift in plankton populations may impact marine food webs, as plankton are crucial for supporting marine life, including fish, crabs, and sea stars  India’s excess sugar production is guzzling groundwater Context: In 2021-2022, India surpassed Brazil to become the largest sugar producer in the world, producing 359 lakh tonnes – an all-time high. Reasons for excess sugar production in India: High consumption (India is the world’s largest sugar consumer) and demand. Government policies and measures: *Central Government’s Fair and remunerative price (FRP) for sugarcane *Mandatory payment of a minimum price to sugarcane farmers by the sugar mills. *Heavy subsidies and incentives by the state governments. *The resulting sugar surplus has led to higher exports, with a record 110 lakh tonnes exported in 2021-2022. How does excessive sugarcane cultivation impact groundwater? Sugarcane is a highly resource-intensive cash crop: it needs a large swath of land and guzzles groundwater. India’s top sugarcane-growing states are Maharashtra, Uttar Pradesh, Karnataka, Gujarat, and Tamil Nadu. The first three account for 85-90% of the sugar produced in the country. In a 2022 report, the Central Ground Water Board (CGWB) noted that a third of all its groundwater assessment units in Maharashtra, Uttar Pradesh, and Karnataka were ‘semi-critical’, ‘critical’ or ‘over-exploited’. Q.) Among the following, which one is the least water-efficient crop?(2021) (a)Sugarcane (b)Sunflower (c)Pearl Millet (d)Red gram  Kattupalli Port Expansion By Adani Group... Kattupalli Port – Tamil Nadu (18 mtpa):The multi-cargo port located near Ennore North Chennai has a dedicated yard for Direct Port Delivery clearance, Direct Port Entry for factory stuffed/self-sealed export-laden containers and flexible carting.  The Mines and Minerals (Development and Regulation) Amendment Bill 2023 Context: Parliament passed the Mines and Minerals (Development and Regulation) Amendment Bill, 2023, (MMDR Amendment) in a bid to attract private sector investment in the exploration of critical and deep- seated minerals in the country. What are critical and deep-seated minerals? Critical Minerals: Critical minerals are natural resources that are essential for various industries, including technology, manufacturing, and clean energy. E.g., Lithium, nickel, cobalt etc. Deep-Seated Minerals: Deep-seated minerals refer to minerals that are found deep within the Earth’s crust and are typically more challenging and costly to explore and mine compared to minerals closer to the surface. E.g., Gold, Copper, Diamonds etc. India’s import dependency for critical and deep-seated minerals: 100% dependency: lithium, cobalt, nickel, niobium, beryllium, tantalum, Very high dependency: copper, zinc, lead, gold, silver, platinum group elements (PGEs), and diamonds. India’s current status: India is the world’s 4th largest producer of iron ore and the 2nd largest producer of coal as of 2021. India is the second-largest producer of Aluminium globally India’s mineral demand is projected to rise by 3% in 2023, fuelled by expanded electrification efforts and overall economic growth  Key provisions of Mines and Minerals (Development and Regulation) Amendment Bill, 2023 Key Provisions MMDR Act 1957 MMDR Amendment Bill Allows the private sector to mine 6 atomic minerals- lithium, beryllium, niobium, titanium, tantalum and zirconium. Private Sector to Mine Atomic Limited to State agencies for Minerals exploration. The central government can auction mining leases and composite licences for critical minerals.  The state government No provision for an grants licences through Auction for Exploration exploration licence competitive bidding, while Licence the Central government auction. prescribes auction details. Bill allows activities under a Maximum Area in which Prospecting licence: Up single exploration licence in Activities are to 25 sq. km. an area of up to 1,000 square kilometres. Mines and Minerals Bill 2023 endeavours to stimulate private sector involvement through: The Bill excludes six atomic minerals that were previously reserved exclusively for government entities The Bill overturns the Act’s prohibition on certain exploration activities like pitting, trenching, drilling, and sub-surface excavation. The Bill introduces a new exploration license (EL) aimed at promoting reconnaissance-level and prospective-stage exploration by private players. The Bill specifies the maximum exploration area, allowing activities within 1,000 square kilometres under a single exploration license. The Bill empowers the central government to conduct auctions for composite licenses and mining leases specifically for critical and strategic minerals. Economic Community of West African States (ECOWAS) Context: In the ongoing crisis in Niger, where a military coup ousted the president, ECOWAS has been active. Recently, soldiers in Niger overthrew President Mohamed Bazoum and placed Gen. Abdourahmane Tchiani as the new head of state. What is ECOWAS? The Economic Community of West African States or ECOWAS was established in 1975 through the Lagos Treaty, with a mandate of promoting economic integration among its members. ECOWAS has 15 members: Benin, Burkina Faso, Cape Verde, Cote d’ Ivoire, The Gambia, Ghana, Guinea, Guinea Bissau, Liberia, Mali, Niger, Nigeria, Sierra Leone, Senegal and Togo.

In one of the worst natural disasters to hit the US, multiple wildfires are raging through Hawaii, especially the island of Maui. Hawaii Hawaii is a U.S. state located in the Pacific Ocean and is composed of a group of islands. The capital city of Hawaii is Honolulu, located on the island of Oahu. Islands Hawaii is made up of eight main islands: Hawaii (also known as the Big Island), Maui, Oahu, Kauai, Molokai, Lanai, Niihau, and Kahoolawe. These islands are part of an archipelago formed by volcanic activity. Volcanoes Hawaii is home to some of the world's most active volcanoes, including Kilauea and Mauna Loa. Climate Hawaii has a tropical climate, with warm temperatures throughout the year. Experts have recently warned pesticide sellers against the sale and storage of glyphosate as its exposure is known to cause cancer. About Glyphosate: Glyphosate is a widely used herbicide that can kill certain weeds and grasses. The product is used primarily in agriculture but also in forestry and lawn and garden care. Glyphosate is a small molecule made of a linear carbon chain with weaker bonds, which makes glyphosate less persistent in the environment. In India, it goes by various brand names, including Roundup, Glycel, and Brake. Note ;- It is effective only on plants that grow above the water. It will not be effective on plants that are submerged or have most of their foliage underwater, nor will it control regrowth from seed. Systemic Nature: Glyphosate is a systemic herbicide, which means it is absorbed by the plant's leaves and then translocated throughout the plant's vascular system. This allows it to reach various parts of the plant, including the roots, leading to effective control of both above-ground and below-ground plant parts. Glyphosate does not degrade quickly in plants. It is possible that glyphosate residues can occur in food products. Nawegaon-Nagzira Tiger Reserve CONTEXT :- A young male tiger recently died in a road hit near Murdoli village in the buffer zone of the Nawegaon-Nagzira Tiger Reserve in Maharashtra. Location: It is situated in Gondia and Shahdara District of Maharashtra.

The cooked rice is unique and possesses a harmonious blend of taste, aroma and rich organoleptic properties.  Oldest surviving plant species saw dinosaurs come and go, humans threaten it Context :- Takakia, a genus of moss that has survived for millions of years, is now threatened by climate change. About Takakia: It is a rare genus of moss that adapted over millions of years to life at high altitudes. Appearance: When seen from a distance, it looks like a later of moss or green algae on the rocks where it grows. But closer inspection would reveal slender turf around one centimetre in length with an arrangement of short, finger-like leaves. It is a genus that only has two species (T. lepidozioides and T. ceratophylla ) and both of them are found together only in the Tibetan Plateau. It has developed the ability to survive frost, life-threatening UV radiation and other hazardous conditions. It combines features found in mosses, liverworts and green algae. It is a moss that separated from other mosses 390 million years ago, not long after the first land plants evolved. SPONGE CITIES Context China's "sponge city" initiative and its efforts to address the challenges posed by urban flooding and water management. Sponge City :- The "sponge city" is an urban planning model designed to use "nature-based solutions" to distribute water better and improve drainage and storage. Those solutions included the use of permeable asphalt, the construction of new canals and ponds and also the restoration of wetlands, which would not only ease waterlogging but also improve the urban environment. Importance of sponge cities in mitigating floods: (1) Rainwater Absorption and Retention (2)Natural Water Storage (3)Green Infrastructure (4)Improved Drainage Systems (5)Improved water table (6)Climate Resilience Sponge cities have seen limited success due to the following challenges: (1) High Initial Costs (2)High Maintenance Demands (3)Logistically challenging and require careful coordination, integrating with Existing Infrastructure. (4)resistance from traditional urban planning practices and stakeholders accustomed to conventional systems.  Scientists detect ‘microplastics’ in human heart for first time: Report CONTEXT;- Scientists from Beijing Anzhen Hospital in China made the discovery while analysing the heart tissue of 15 patients who underwent cardiovascular surgery. About Findings: 1. For the first time, they have detected microplastics in human hearts. 2. Researchers found these incredibly small particles, occasionally as tiny as a grain of sand, within the heart tissues of individuals from various locations. 3. It also makes us think about how plastic might affect our health. This discovery has serious implications for both pollution and human well- being. About Microplastics Microplastics are tiny bits of various types of plastic found in the environment. They are a result of the fragmentation and degradation of larger plastic items, as well as the direct release of tiny plastic particles, often intentionally added to consumer products like cosmetics and cleaning agents. Microplastics are those particles with less than 5 millimeters (0.2 inches). Types of Microplastics? There are two categories of microplastics: primary and secondary. Primary microplastics: (1)Tiny particles designed for commercial use, such as cosmetics, as well as microfibers shed from clothing and other textiles, such as fishing nets. (2)They enter the environment directly through any of various channels— for example, product use, unintentional loss from spills during manufacturing or transport, or abrasion during washing. Secondary microplastics: (1)They are particles that result from the breakdown of larger plastic items, such as water bottles. (2)This typically happens when larger plastics undergo weathering, through exposure to, for example, wave action, wind abrasion, and ultraviolet radiation from sunlight. Recently, the National Green Tribunal, Eastern Zone, has directed the Odisha government not to go ahead with ‘illegal’ construction in and around Tampara Lake. About Tampara Lake: It is one of the largest fresh water lakes in the State of Odisha.

CONTEXT :- Tamandua Piripkura has lived his life on the run. Not from authorities or enemies — although plenty of people would like to see him dead — but from modernity. About Piripkura Tribe: They are nomadic tribe from Mato Grasso region of Brazil. The tribe is known for its isolation and efforts to maintain its traditional way of life. These people have faced significant challenges due to encroachment on their land by illegal logging, mining, and other forms of land exploitation. Their territory has been under threat from deforestation and resource extraction.  Now, a bacteria that can eat methane. Can it reduce global warming? Researchers say it’s possible What is the News? A study has found that a specific bacteria named Methylotuvimicrobium buryatense 5GB1C could help reduce methane emissions from places like landfills and oil wells. What is Methylotuvimicrobium buryatense 5GB1C? Methylotuvimicrobium buryatense 5GB1C is a bacterial strain that consumes methane. It can grow at low methane concentrations ranging from 200-1,000 ppm. These features make this strain a promising candidate for methane removal technology. Significance: Methane is a significant contributor to global warming, It is over 85 times more potent than carbon dioxide (CO2) on a 20-year timescale. It is responsible for nearly 30 percent of the total global warming. Hence, this bacteria, if used on a large scale, could prevent 240 million tonnes of methane from entering the atmosphere by 2050. It can also help reduce the global temperature rise by about 0.21-0.22 degrees Celsius by 2050 by removing a substantial amount of methane  Prelims Pointer :- Addis Ababa Declaration CONTEXT :- Declaration was a key outcome of the 19th African Ministerial Conference on the Environment (AMCEN) 2023, held in Addis Ababa, Ethiopia. The declaration prioritizes wide-ranging actions related to climate change, plastics pollution, marine protection, land degradation, and natural capital. Signed by 54 African Nations Decision deferred as concerns raised over Jambughoda Sanctuary Context :- Recently, the Gujarat State Board for Wildlife (GSBWL) deferred a decision on a proposal of the Gujarat State Minerals Development Corporation (GSDMA) seeking more land for “removing manganese dump” from the eco-sensitive zone (ESZ) of Jambughoda Wildlife Sanctuary in Panchmahal district. About Jambughoda Wildlife Sanctuary: It is located in Gujarat’s south-central part. Vegetation: It contains Grasslands, water-borne plants, medicinal herbs, dry southern tropical rain forests, dry deciduous mixed and secondary forests, and dry scrubs of the deciduous type. What are Eco-Sensitive Zones? Land within 10 km of the boundaries of national parks and wildlife sanctuaries is to be notified as eco-fragile zones or Eco-Sensitive Zones (ESZ). While the 10-km rule is implemented as a general principle, the extent of its application can vary. The Union government can also notify areas beyond 10 km as ESZs if they hold larger ecologically important “sensitive corridors”. Why are Eco-Sensitive Zones created? They are created as “shock absorbers” for the protected areas to minimise the negative impact on the “fragile ecosystems” by certain nearby human activities. these areas are meant to act as transition zone from areas requiring higher protection to those requiring lesser protection. The Indian Prime minister was recently conferred with the Grand Cross of the Order of Honour by the Greek President in Athens. Key Facts about Greece: Location: It is located in southeastern Europe, on the southern tip of the Balkan Peninsula. Bordering Countries: Country is bordered by Albania, Bulgaria, Turkey, and North Macedonia. Greece shares maritime borders with Cyprus, Egypt, Italy, and Libya. Geography: The mainland has rugged mountains, forests, and lakes. It is well known for the thousands of islands dotting the blue Aegean Sea to the east, the Mediterranean Sea to the south, and the Ionian Sea to the west. The largest Greek island is Crete. Capital: Athens  Extra Points :- Political System: It is a parliamentary republic with a head of government - the prime minister - who has the most political power, and the head of state - the president - whose duties are largely ceremonial. The executive power is exercised by the government. Olympics: The Olympic Games have their origins in ancient Greece, where the first Olympic Games were held in Olympia in 776 BC. Greece also hosted the first modern Olympic Games in Athens in 1896. Recently:- At least 78 people have died and many more are feared missing after a fishing boat carrying refugees and migrants capsized and sank off the southern coast of Greece – one of the worst such disasters this year. The vessel sank in international waters, 47 nautical miles (87km) southwest of Pylos, off the Peloponnese coast.  The Fujiwhara effect: When cyclones ‘dance’ Context :- Earlier this year, California witnessed an unusually wet winter, with at least twelve atmospheric river storms battering the state. Atmospheric rivers are vast airborne currents carrying dense moisture and hanging low in the atmosphere. About The Fujiwhara effect: The “Fujiwhara effect,” where two cyclones (or hurricanes) spinning in the same direction interact in a dance-like manner around a common centre. If one cyclone is stronger, it can absorb the weaker one. When of similar strength, they might merge or rotate around each other. In some rare instances, the two cyclones could merge into a mega-cyclone with significant destructive potential. Associated damages:- The influx of additional heat, moisture, and positive vorticity during the Fujiwhara effect intensify the primary circulation of a system. The occurrence of the Fujiwhara effect also makes cyclonic systems harder to predict, as every interaction between two storm systems is unique and difficult to assess within the present climate models. How is this related to today’s climate? Experts have noted the rising frequency of this unusual effect, attributing it to a rapidly warming world and the subsequent heating of ocean waters. A warming climate is giving rise to stronger cyclones, and thus, increasing the possibility of the Fujiwhara effect. NGT withholds green nod granted for fishing harbours near Kaliveli bird sanctuary About Kaliveli Bird Sanctuary: This wetland is the second-largest brackish water lake in South India after Pulicat Lake. The Kaliveli Lake is connected to the Bay of Bengal by the Uppukalli Creek and the Edayanthittu sanctuary and is visited for nesting by migratory birds on the Central Asian flyway.

Major Export Destinations (2021-22): Bangladesh, Malaysia, Sri Lanka, United Arab EMTs, Nepal and Indonesia. Govt imposes 20% export duty on parboiled rice; MEP on basmati coming About Parboiled Rice: Parboiled rice, also called converted rice, is partially precooked in its inedible husk before being processed for eating. It happens before rice is milled, that is, before the inedible outer husk is removed to yield brown rice but before brown rice is refined to make white rice. In some Asian and African countries, people have been parboiling rice since ancient times as it makes the husks easier to remove by hand. Main steps of parboiling are:- Soaking Steaming Drying Husking  Parboiling changes the colour of rice to a light yellow or amber, which differs from the pale, white colour of regular rice. Benefits: 1.improves its texture, increases its shelf life, and provides health benefits. 2.higher in fibre and protein than white rice. 3.reduces the stickiness of rice, so it yields fluffy and separate kernels once cooked. 4.inactivates the enzymes that break down the fat in rice. This helps prevent rancidity and off-flavors, increasing shelf-life 5.has more thiamine and niacin than white rice. These nutrients are important for energy production. Potential downsides: 1.It’s less nutritious than brown rice. 2.It takes a little longer to cook.  Kumbhalgarh Wildlife Sanctuary CONTEXT:- The Union Ministry of Environment, Forest and Climate Change (MoEFCC) recently cleared the National Tiger Conservation Authority (NTCA)’s in-principle approval to declare Kumbhalgarh Wildlife Sanctuary as a tiger reserve. About Kumbhalgarh Wildlife Sanctuary: Location: It is situated in the Rajsamand district of Rajasthan. Once the hunting grounds of royals, this area was declared a wildlife sanctuary in 1971. The wildlife sanctuary encompasses the historic Kumbhalgarh Fortand is also named after the fort. It acts as a dividing line between Mewar and Marwar, two different parts of Rajasthan. Rivers: 1.River Banas also graces the sanctuary and is the primary source of water. 2.The rainwater on the western slopes flows as small rivers such as Sukdi, Mithdi, Sumer and Kot, all of which are the tributaries of River Luni that ultimately merge into the Arabian Sea. Flora: mainly a variety of herbal flora like Dhok, Salar and Khair. Many trees and plants and medicinal plants with herbal properties are also included in it. Fauna: It provides a suitable habitat for endangered and rare wild animals, including four-horned antelope, sambar, wild boar, nilgai, sloth bear, leopard and caracal.  Global South CONTEXT:- Recently, External Affairs Minister S. Jaishankar said that the disruptions caused by the corona virus pandemic and recent geopolitical conflicts call for a realignment of the world order. He said that the “Global South” can no longer be at the mercy of a few suppliers.  The term ‘Global South’ began by loosely referring to those countries that were left out of the industrialisation era. It includes countries that are in Asia, Africa and South America. ‘Global South’ is just the opposite of ‘Global North’, defined essentially by an economic division between the rich and poorer countries. The “Global North” is richer nations that are located mostly in North America and Europe, with some additions in Oceania and elsewhere. What Is Magic Rice? What Is Special About This Rice That It Got GI Tag About Chokuwa rice: It is also known as Magic rice cultivated in Assam. This unique and healthy rice is cultivated around the Brahmaputra River area.(In several parts of Assam like Tinsukia, Dhemaji, Dibrugarh, etc.) It is basically semi-glutinous winter rice, known as Sali rice. The sticky and glutinous variety is categorised as Bora and Chokuwa based on their amylose concentration. The low amylase Chokuwa rice variants are used to make soft rice, which is known as Komal Chaul or soft rice. This whole grain can be consumed after soaking the rice in cold or lukewarm water. This unique rice variety is consumed with curd, sugar, jaggery, and bananas to name a few. This rice is also used in making several Assamese delights like Pithe and other local dishes. Catering to an elephant’s diet to prevent conflicts with humans in Assam CONTEXT:-The initiative to plant 25,000 saplings of native trees is expected to secure an elephant habitat and mitigate human-elephant conflicts in the Udalguri district bordering Bhutan  Several native species of trees are being planted in Assam to secure a major elephant habitat and mitigate conflicts between humans and tuskers. Species include Amla (Phyllanthus emblica), Bel (Aegle marmelos), Gamhari (Gmelina arborea), Jamun (Syzygium cumini), Bhumura (Terminalia bellirica), Arjun (Terminalia arjuna) etc. Most of these plants are important for the elephants’ diet. Restoring degraded areas with tree species preferred by the elephants would help secure its habitat and facilitate elephant movement. MINISTRY OF JAL SHAKTI RELEASES THE 6TH CENSUS REPORT ON MINOR IRRIGATION (MI) SCHEMES Census has been conducted under the centrally sponsored scheme “Irrigation Census” of Ministry of Jal Shakti. MI schemes are defined as those structures either in groundwater or in surfacewater category having Culturable Command Area (area which can be irrigated from a scheme and is fit for cultivation) up to 2,000 hectares. MI schemes can be categorized broadly into following types: Dugwell, Shallow tubewell, Medium Tubewell, Deep tubewell,Surface flow schemes, and Surface lift schemes. Advantage of MI projects: Short gestation period, require smaller investment and benefit reach the farmer. Key Highlights:- 23.14 million MI schemes have been reported, out of which 94.8% are Ground Water schemes. UP possesses largest number of MI schemes followed by Maharashtra, MP and Tamil Nadu. Increase of about 1.42 million in MI schemes during 6th census as compared to 5th Census. 96.6% of MI schemes continue to remain under private ownership. Reroute railway track running through Assam gibbon sanctuary, suggest scientists Hollongapar Gibbon Sanctuary: The Hoollongapar Gibbon Sanctuary was renamed on 25 May 2004, formerly known as the Gibbon Wildlife Sanctuary or Hollongapar Reserve Forest. It is an isolated protected area of evergreen forest located in the Jorhat district of Assam. Vegetation: The upper canopy of the forest is dominated by the Hollong tree, while the Nahar dominates the middle canopy. The lower canopy consists of evergreen shrubs and herbs. Key facts about Hoolock Gibbon :- It is the only ape found in India. It is native to eastern Bangladesh, Northeast India, Myanmar, and Southwest China. Gibbons, the smallest and fastest of all apes, live in tropical and subtropical forests in the southeastern part of Asia. The Hoolock gibbon, unique to India’s northeast, is one of 20 species of gibbons on Earth. It is categorised into Western Hoolock Gibbon and Eastern Hoolock Gibbon. Western Hoolock Gibbon It has a much wider range, as it is found in all the states of the northeast, restricted between the south of the Brahmaputra River and east of the Dibang River. It is listed as Endangered on the IUCN Red List. Eastern Hoolock gibbon It inhabits specific pockets of Arunachal Pradesh and Assam in India, and southern China and northeast Myanmar. It is listed as Vulnerable in the IUCN Red list.  Curious and cryptic: New leaf insects discovered CONTEXT :- An international research team recently described seven previously unknown species of leaf insects, also known as walking leaves. About Walking Leaves: Walking Leaves, also called leaf insects, are insects that look very similar to leaves. They are any of more than 50 species of flat, usually green insects (order Phasmida or Phasmatodea) that are known for their striking leaflike appearance. They feed on plants and typically inhabit densely vegetated areas. Distribution: Their natural range extends from islands in the Indian Ocean, across parts of mainland South Asia and Southeast Asia, to Papua New Guinea and Australia in the western Pacific. Males tend to be smaller than females. Reproduction: These insects reproduce sexually, with females laying eggs. The arms and legs of walking leaves can regenerate. About Supermoon: A supermoon occurs when the Moon’s orbit is closest to the Earth at the same time that the Moon is full. As the Moon orbits the Earth, there is a point of time when the distance between the two is the least (called the perigee when the average distance is about 360,000 km from the Earth) and a point of time when the distance is the most (called the apogee when the distance is about 405,000 km from the Earth). Now, when a full Moon appears at the point when the distance between the Earth and the Moon is the least, not only does it appear to be brighter but it is also larger than a regular full moon. According to NASA, a full moon at perigee (super moon) is about 14% bigger and 30% brighter than a full moon at apogee (called a “micro moon”). What is a blue moon? Blue moon describes the situation when a full moon is seen twice in a single month. It is important to note that the term Blue Moon has nothing to do with the actual colour of the moon. Moons can appear in various shades depending on atmospheric conditions, but a Blue Moon is not necessarily blue in colour. How rare is a blue supermoon? According to NASA, the blue supermoons are a very rare phenomenon. It mentions that these moons often only appear once every ten years due to astronomical conditions. But occasionally, the interval between blue supermoons can be as long as twenty years. The following super blue moons will take place in pairs in 2037, in January  Maritime Security in Pacific region: US - new pact with Palau CONTEXT :- The United States has signed a new agreement with Palau, which gives American ships the authorisation to unilaterally enforce maritime regulations in the tiny Pacific Island nation’s exclusive economic zone  Palau (officially the Republic of Palau with capital Ngerulmud) is an island country in the Micronesia sub-region of Oceania in the western Pacific. The republic consists of approximately 340 islands and has a total area of 466 sq kms, making it one of the smallest countries in the world. The 140+ members of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) have gathered at Bonn, Germany for the body’s 10th plenary. On agenda is the scientific assessment report on “Invasive Alien Species and their Control”, which is set to be released to the public on September 4, 2023. The delegates at the plenary would approve the text of the report that has taken four years to be developed by 86 leading experts from 49 countries. Invasive alien species are a key driver of biodiversity loss and they are part of the targets set under the Kunming-Montreal Global Biodiversity Framework (GBF) adopted by 193 members of the Convention on Biological Diversity in December 2022. The GBF has 23 targets that have to be met by 2030. About IPBES: It is an independent intergovernmental body established in 2012. It provides policymakers with objective scientific assessments about the state of knowledge regarding the planet’s biodiversity, ecosystems and the benefits they provide to people, as well as the tools and methods to protect and sustainably use these vital natural assets. This independent body was inspired by the Intergovernmental Panel on Climate Change (IPCC) and the Millennium Ecosystem Assessment. It is not a United Nations body. However, at the request of the IPBES Plenary and with the authorisation of the UNEP Governing Council in 2013, the United Nations Environment Programme (UNEP) provides secretariat services to IPBES. India is a member country of this organisation  Funga: UN wants us all to say it along with ‘Flora & Fauna’ CONTEXT:- United Nations Biodiversity has urged people globally to use the word ‘funga’ whenever they say ‘flora and fauna’, in order to highlight the importance of fungi. About Fungi: Fungi, along with Animalia (animals), Plantae (plants), Protista, Archaea/Archaebacteria, and Bacteria or Eubacteria, form the six ‘kingdoms’ of biology. They are eukaryotic organisms; i.e., their cells contain membrane-bound organelles and clearly defined nuclei. Reproduction: Fungi usually reproduce both sexually and asexually. Distribution Fungi are either terrestrial or aquatic, the latter living in freshwater or marine environments. They are found in all temperate and tropical regions of the world where there is sufficient moisture to enable them to grow. A few species of fungi live in the Arctic and Antarctic regions, although they are rare and are more often found living in symbiosis with algae in the form of lichens. Importance of fungi They help in breaking down dead organic material. They continue the cycle of nutrients through ecosystems. Fungi, as food, play a role in human nutrition in the form of mushrooms. They also act as agents of fermentation in the production of bread, cheeses, alcoholic beverages, and numerous other food preparations. Secondary metabolites of fungi are used as medicines, such as antibiotics and anticoagulants. Chhattisgarh HC dismisses plea seeking tiger reserve status for Bhoramdeo Wildlife About Bhoramdeo Wildlife Sanctuary: Location: It is situated in the Kawardha district of Chhattisgarh.

Fauna: It is home to a variety of wildlife species, including tigers, leopards, wild dogs, sloth bears, sambar deer, barking deer, chital (spotted deer), gaur (Indian bison), and various species of birds and reptiles. What is Leaf Blight? It is a plant disease that affects the foliage (leaves) of various plants, causing discoloration, wilting, and, in severe cases, the death of the leaves. It is typically caused by various types of fungi or bacteria that infect and damage the plant tissues. Leaf blight can affect a wide range of plants, including trees, shrubs, ornamental plants, and crops. Chitala’s river ranching to help balance aquatic ecosystem, raise farmers’ income: Minister About Chitala Fish: It is an obligate, typically nocturnal, predator feeding on smaller fishes. Distribution Although often reported to range throughout most of southern Asia, this species is probably restricted to the Indian subcontinent in Pakistan, India (records from the states of Manipur, Uttaranchal, West Bengal, Assam, Tripura, Uttar Pradesh, and Bihar), Nepal, and Bangladesh. Habitat It is mostly known from major river channels and freshwater lakes but has also been observed in swamps. It is found in the Indus, Ganges-Brahmaputra and Mahanadi river basins in India.

The analysis helps explain how North Atlantic water influences Arctic Ocean climate, a process scientists call “Atlantification. Atlantification of Arctic ocean: Atlantification is the increasing influence of Atlantic water in the Arctic. Warmer and saltier Atlantic water is extending its reach northward into the Arctic Ocean. This change in the Arctic climate is most prominent in the Barents Sea, a shallow shelf sea north of Scandinavia, where sea-ice is disappearing faster than in any other Arctic region, impacting the local and global ecosystem. NOTE:- Researchers believe that Atlantification is driven by a process called Arctic Dipole which is associated with anticyclonic winds over North America and cyclonic winds over Eurasia which alternates in an approximately 15-year cycle. Positive phase of Arctic Dipole contributed to slowing Arctic sea-ice loss by restricting Atlantic water into the Arctic via the Fram Strait and negative phase accelerate sea-ice decline. Fram strait: The Fram Strait is the passage between Greenland and Svalbard. The Greenland and Norwegian Seas lie south of Fram Strait, while the Nansen Basin of the Arctic Ocean lies to the north. Fram Strait is noted for being the only deep connection between the Arctic Ocean and the World Oceans.  New Delhi Declaration & Climate Commitments Why in News?

The researchers say, "We know that cirrus clouds can contribute to global warming. About Cirrus Clouds: They are delicate, feathery clouds that are made mostly of ice crystals. They are thin and wispy in appearance, often appearing as delicate, high-altitude filaments or strands. Their wispy shape comes from wind currents, which twist and spread the ice crystals into strands. They are commonly known as "mare's tails" because they are shaped like the tail of a horse. Typically found at heights greater than 20,000 feet (6,000 metres), cirrus clouds are composed of ice crystals that originate from the freezing of supercooled water droplets. They generally occur in fair weather and point in the direction of air movement at their elevation. Madhya Pradesh: Gandhi Sagar wildlife sanctuary to be new home for South African cheetahs About Gandhi Sagar Wildlife Sanctuary Location: It is situated in Madhya Pradesh.
