- Recently, two young individuals lost their lives in a tragic incident in the Bhima River at Ganagapur, located in the Kalaburagi district.
- About the Bhima River:
- The Bhima River, also known as the Chandrabagha River, is the principal tributary of the Krishna River.
- Course:
- The river begins near the Bhimashankar Temple, situated in the Bhimashankar hills on the western edge of the Western Ghats in Pune District, Maharashtra.
- It travels southeast through the states of Maharashtra, Karnataka, and Telangana.
- The Bhima River eventually converges with the Krishna River in Raichur district, Karnataka.
- Geography:
- Stretching over 861 km, the river is flanked by the Western Ghats to the west, the Balaghat Range to the north, and the Mahadeo Hills to the south.
- Its basin spans an area of 48,631 sq. km, with 75% of this area located in Maharashtra.
- The river flows through a deeply entrenched valley and its banks are densely populated.
- Water Levels:
- The water level of the Bhima River is influenced by the monsoon season; it experiences flooding in August due to the rains and becomes nearly stagnant during March and April.
- Tributaries:
- Significant tributaries include the Indrayani, Mula, Mutha, and Pavana Rivers.
- Notable Locations:
- Pandharpur, a major pilgrimage destination, is situated on the right bank of the Bhima River.
- The Reserve Bank of India has recently introduced a framework for the recognition of self-regulatory organizations (SROs) within the financial markets.
- About Self-Regulatory Organizations (SROs):
- An SRO is typically a non-governmental body established by members of a specific industry or sector to oversee and regulate entities within that field.
- Functions and Purpose:
- An SRO develops and enforces rules and standards governing the conduct of its member organizations, aiming to safeguard consumers and promote ethical behavior, fairness, and professionalism.
- SROs work collaboratively with stakeholders to establish and update industry regulations.
- They operate through impartial systems to ensure that members adhere to disciplined practices and accept penalties for non-compliance.
- SROs are designed to address broader issues beyond the immediate interests of the industry, such as protecting workers, consumers, and other participants within the ecosystem.
- Regulatory Role:
- While SROs are private entities, they are still subject to some degree of government oversight. However, certain regulatory responsibilities are delegated to these organizations.
- Despite being privately managed, SROs often serve as a watchdog to prevent fraud and unethical practices within their industry.
- Their regulatory authority typically arises from internal mechanisms or agreements among businesses, rather than direct government delegation.
- The primary goal of SROs is to regulate and monitor industry practices internally, maintaining a degree of separation from direct governmental control.
- Recently, approximately 40 Chinese yaks crossed into Indian territory in the Demchok region of eastern Ladakh and are currently under the management of local villagers.
- About Yaks:
- Yaks are large herd animals native to the Himalayan region, the Tibetan plateau, and Mongolia, known for their long, humped coats.
- Scientific Classification:
- Wild yaks are often classified as a distinct species (Bos mutus) from domestic yaks (Bos grunniens), although they can interbreed with various types of cattle.
- Habitat:
- Wild yaks inhabit alpine tundra at elevations ranging from 5,000 to 7,000 meters, while domestic yaks are adapted to lower altitudes.
- Their habitats include diverse vegetation zones: alpine meadows, alpine steppes, and desert steppes.
- In India, yak-rearing regions include Arunachal Pradesh, Sikkim, Uttar Pradesh, Himachal Pradesh, and the union territories of Jammu and Kashmir and Ladakh.
- Physical Features:
- Wild yaks are approximately two meters tall at the shoulder, while domestic yaks are roughly half that height.
- Both types are covered in long, shaggy fur to protect them from the cold.
- Both sexes of yaks have curved horns, with males typically having larger horns than females.
- Wild yaks are usually brown or black, while domestic yaks can also be white.
- Yaks have a lung capacity about three times greater than that of cattle and possess more and smaller red blood cells, enhancing their oxygen transport efficiency.
- They are herbivorous.
- Uses:
- Domesticated yaks are primarily raised for their milk and meat.
- They serve as pack animals, transporting goods across mountain passes for local farmers and traders and supporting climbing and trekking expeditions.
- Yaks are adept at navigating steep mountain terrain and can ascend to altitudes of up to 20,000 feet.
- Conservation Status:
- Wild yaks are classified as ‘Vulnerable’ on the IUCN Red List.
- The US Centers for Disease Control and Prevention (CDC) has recently issued a health advisory due to a concerning increase in cases of parvovirus B19.
- About Parvovirus B19:
- Parvovirus B19 is a highly contagious illness, particularly affecting individuals with weakened immune systems. It is often referred to as the "slapped cheek" disease because it causes a distinctive reddening of the cheeks. This infection is also known as ‘Fifth disease’ due to its historical position as the fifth illness in a list of common childhood rashes.
- Transmission:
- The virus spreads through airborne droplets released when an infected person coughs or sneezes.
- It can also be transmitted through blood or contaminated blood products.
- Pregnant individuals with parvovirus B19 can transmit the virus to the fetus via the placenta.
- Complications:
- While parvovirus infection is generally mild in children and requires minimal treatment, it can be more severe in adults.
- In pregnant women, the infection may lead to serious complications for the fetus.
- Individuals with certain types of anemia or compromised immune systems are at higher risk of severe complications.
- Symptoms:
- Many people with parvovirus B19 infection show no symptoms.
- When symptoms do occur, they can vary significantly depending on age.
- Common symptoms include the "slapped cheek" rash in children and joint pain in adults.
- Treatment:
- Parvovirus B19 infections are typically mild and resolve on their own.
- Treatment generally focuses on relieving symptoms, such as fever, itching, and joint pain and swelling.
- The Chhattisgarh Forest Department recently held a Van Mahotsav event in the Manendragarh-Chirmiri-Bharatpur (MCB) district, where saplings were planted using the Miyawaki method.
- About the Miyawaki Method:
- The Miyawaki method is a technique for afforestation developed by Japanese botanist and plant ecologist Professor Akira Miyawaki.
- Methodology:
- This approach involves planting two to four types of indigenous trees per square meter.
- The dense planting causes the seedlings to grow rapidly as they compete for sunlight.
- Only native species that naturally occur in the region without human intervention, considering the specific climate, are chosen for planting.
- The species selection is based on the concept of Potential Natural Vegetation (PNV), which represents the natural vegetation that would be present in an area without human influence.
- Benefits and Features:
- Trees in Miyawaki forests achieve self-sustainability and reach their full height within about three years.
- Miyawaki forests grow ten times faster, are thirty times denser, and support one hundred times more biodiversity than traditional forests.
- They establish quickly, require minimal maintenance after the initial two to three years, and can be created in areas as small as three square meters.
- The goals of using the Miyawaki technique include enhancing biodiversity, sequestering carbon, increasing green cover, reducing air pollution, and preserving the water table.
- Application:
- Miyawaki forests provide a practical solution for cities seeking to rapidly enhance climate resilience.
- The method is effective due to its reliance on natural reforestation principles, which involve using native trees and mimicking natural forest regeneration processes.
