Bharat Forecasting System Launched Syllabus :GS 1/Geography The Ministry of Earth Sciences has launched the Bharat Forecasting System (BFS) to revolutionize weather prediction in India. Developed by the Indian Institute of Tropical Meteorology (IITM), Pune, BFS delivers highly localized weather forecasts with a cutting-edge 6 km grid resolution—the highest in the world. It enables more accurate prediction of small-scale weather phenomena across India. Powered by Supercomputer Arka (Speed: 11.77 petaflops, Storage: 33 petabytes), BFS now generates forecasts in 4 hours, compared to 10 hours by the earlier system, Pratyush. It focuses on the tropical belt (30°S to 30°N), including entire India, and surpasses global models from the U.S., UK, and Europe (with 9–14 km resolution). It integrates data from 40 Doppler Weather Radars (to be scaled to 100) and provides nowcasting for the next 2 hours. BFS boosts India’s self-reliance in weather prediction and enhances disaster preparedness, agricultural planning, water resource management, and public safety at local levels. It supports India’s commitment to the Sendai Framework for Disaster Risk Reduction and marks a major leap in India’s capability to deliver accurate, timely, and actionable forecasts from national to panchayat-level scale. With reference to the Bharat Forecasting System (BFS), consider the following statements: It is the first global model to offer sub-10 km resolution for weather forecasts. It uses a combination of ensemble and deterministic forecasting techniques. It has real-time integration with satellite-derived precipitation and land-surface data. It is developed under the National Monsoon Mission by IITM, Pune. Which of the statements given above are correct? A. 1 and 2 onlyB. 2 and 3 onlyC. 2, 3 and 4 onlyD. 1, 2, 3 and 4 Correct Answer: C. 2, 3 and 4 only Explanation: The Bharat Forecasting System (BFS) does indeed offer a 6 km × 6 km grid resolution, which is among the highest globally for operational regional weather models. However, it is not the first model globally to offer sub-10 km resolution. Some non-global or specialized regional models (e.g., Japan’s JMA models, or high-resolution models for small regions in Europe) have already operated at similar or finer resolutions. Also, BFS is not a global model — it is designed primarily for the tropical belt (30°S to 30°N), including India, so the claim of being a first global model is inaccurate. The BFS employs ensemble forecasting (multiple simulations for probabilistic forecasts) and deterministic forecasting (single high-accuracy prediction). This hybrid approach improves both accuracy and confidence intervals in weather prediction.              BFS integrates real-time observational data from multiple sources: Satellite data (for cloud cover, precipitation, temperature) Land-surface observations (e.g., soil moisture, surface temperature) Doppler Weather Radars (currently 40, expanding to 100) This enhances both short-term (nowcasting) and medium-range forecasts. Iran Slams Trump’s Plan to Rename Persian Gulf Syllabus: GS2/IR/GS1/Places in News            Former U.S. President Donald Trump’s proposal to rename the Persian Gulf as the ‘Arabian Gulf’ or ‘Gulf of Arabia’ sparked sharp criticism from Iran, which viewed the move as a direct challenge to its national identity and historical heritage. The suggestion reportedly surfaced in anticipation of Trump’s visit to Saudi Arabia, Qatar, and the United Arab Emirates.     About the Dispute: The Persian Gulf is a geopolitically and economically vital water body located in Western Asia. It connects to the Gulf of Oman and the Arabian Sea through the strategically crucial Strait of Hormuz. The countries bordering it are Iran, Iraq, Kuwait, Saudi Arabia, Bahrain, Qatar, and the UAE. While Iran insists on the historical term Persian Gulf, Arab Gulf States (except Iran) often refer to it as the ‘Arabian Gulf’ or simply ‘the Gulf’, sparking an ongoing naming dispute that reflects deeper regional rivalries and identity politics.   Historical Background: The term Persian Gulf is rooted in antiquity, referring to Persia, the former name of Iran. In 1935, Reza Shah Pahlavi officially changed the country’s international name from Persia to Iran, asserting that Persia was an exonym (a name given by outsiders) and promoting Iran, the country’s endonym (a native name), to reinforce national sovereignty. This naming controversy continues to carry geopolitical weight, symbolizing broader tensions between Iran and its Arab neighbors. With reference to the geopolitical discourse surrounding the Persian Gulf naming controversy, consider the following statements: The term “Persian Gulf” has been historically recognized in international treaties and cartographic references predating modern nation-states in West Asia. The Strait of Hormuz, connecting the Persian Gulf to the Arabian Sea, lies entirely within the territorial waters of Iran. The move by some Arab states to promote the term “Arabian Gulf” is aligned with pan-Arab political assertions post-World War II. The United Nations has officially adopted “Arabian Gulf” as the standardized name for international usage. Which of the statements given above is/are correct? A. 1 and 3 onlyB. 2, 3 and 4 onlyC. 1, 2 and 3 onlyD. 1 and 4 only Correct Answer: A. 1 and 3 only Explanation: Statement 1 – Correct: The name Persian Gulf has been consistently used in historical maps, naval treaties, and geographical references dating back over two millennia, especially in Greek, Roman, and Islamic sources. It remains the official designation used by the United Nations. Statement 2 – Incorrect: The Strait of Hormuz is not entirely within Iranian waters. It is a narrow waterway bordered by both Iran to the north and Oman (specifically the Musandam exclave) to the south, making it an international strait subject to maritime law. Statement 3 – Correct: The push to rename the Persian Gulf as the Arabian Gulf gained momentum particularly in the mid-20th century, in line with the rise of Pan-Arab nationalism and the political identity consolidation of Arab states in the Gulf region. Statement 4 – Incorrect: The United Nations and most international organizations continue to use “Persian Gulf” as the official name. Any alternative naming is considered politically charged and is not recognized by global institutions.

Orans Syllabus:Polity The Rajasthan government has begun the formal process of classifying Oran lands—community-managed sacred groves—as forests, in compliance with the Supreme Court’s landmark judgment on December 18, 2024. This decision comes under the purview of the Forest Conservation Act, 1980, aiming to strengthen the legal protection of these ecologically and culturally significant landscapes.   About Orans: Definition: Orans are traditional sacred groves preserved by rural communities in Rajasthan, often dedicated to local deities and associated with socio-religious practices. Ecological Significance: They serve as biodiversity hotspots and support critical ecological functions such as: Livelihood support through grazing and forest produce. Water conservation via features like talabs (ponds), nadis (small ponds), open wells, and seasonal streams. Cultural Role: Annual religious festivals and fairs are organized in these groves, reinforcing community stewardship. Extent: Rajasthan houses approximately 25,000 orans spread across 6 lakh hectares. Some, like the Bhadariya Mata Oran in Jaisalmer, span over 17,000 hectares. Conservation Value: Orans are vital habitats for endangered species, notably the Great Indian Bustard (GIB)—India’s most critically endangered bird and the state bird of Rajasthan.   Policy and Legal Developments: The Rajasthan Forest Policy 2023 classified orans merely as general community lands, which provided limited conservation safeguards. The Supreme Court’s 2024 judgment recognized orans as forests under the Forest Conservation Act, enhancing their legal protection against encroachment and ecological degradation.   With reference to the traditional ‘Orans’ of Rajasthan, consider the following statements: Orans are recognized under the Wildlife Protection Act, 1972, as Community Reserves notified by State governments. The Supreme Court’s judgment in December 2024 mandated their classification as forests under the Forest Conservation Act, 1980. Orans have no role in the hydrological cycle, as they are primarily cultural and religious spaces. The Great Indian Bustard, a critically endangered bird species, is found exclusively in protected national parks and not in community lands like Orans. Which of the statements given above is/are correct? A) 1 and 2 onlyB) 2 onlyC) 2 and 3 onlyD) 1, 3, and 4 only Answer: B) 2 only Explanation: Statement 1: Incorrect – Orans are not uniformly notified as Community Reserves under the Wildlife Protection Act, though some may qualify. They are traditionally protected community lands. Statement 2: Correct – The Supreme Court, in December 2024, recognized Orans as forests under the Forest Conservation Act, 1980. Statement 3: Incorrect – Orans often contain vital water bodies (e.g., Talab, Nadi) and play a significant role in the hydrological cycle and local ecology. Statement 4: Incorrect – The Great Indian Bustard is indeed found in Orans, which are vital habitats outside formal protected areas.
