2. Rohingya refugees mark the anniversary of their exodus and demand a safe return to Myanmar
Sub: IR
Sec: Places in news
Context:
- Rohingya refugees living in camps in Bangladesh demanded a safe return to Rakhine state on the seventh anniversary of their mass exodus.
Who are Rohingyas?
- Rohingya are an ethnic group, largely comprising Muslims, who predominantly live in the Western Myanmar province of Rakhine.
- The Rohingya are culturally and religiously distinct from the majority Buddhist population in Myanmar.
- They speak a dialect of Bengali, as opposed to the commonly spoken Burmese language.
- They have suffered decades of violence, discrimination and persecution in Myanmar.
Citizenship issue:
- Though Rohingyas have been living in Myanmar for generations, Myanmar considers them as persons who migrated to their land during the colonial rule and has not granted Rohingyas full citizenship.
- According the 1982 Burmese citizenship law, a Rohingya (or any ethnic minority) is eligible for citizenship only if he/she provides proof that his/her ancestors have lived in the country prior to 1823.
- Else, they are classified as “resident foreigners” or as “associate citizens”.
- Since they are not citizens, they are not entitled to be part of civil service and their movements are also restricted within the Rakhine state.
What happened on 25th August 2017?
- The Arakan Rohingya Salvation Army (ARSA), a militant group staged a coordinated attack on 30 police posts and an army base in Rakhine state on August 25, 2017.
- Myanmar launched a brutal crackdown following the attacks.
- The scale, organization and ferocity of the operation led to accusations from the international community, including the UN, of ethnic cleansing and genocide.
- Thousands of Rohingyas fled their homes and sought refuge in neighbouring Bangladesh, a Muslim-majority nation.
- Some of them sought asylum in Thailand, The Philippines, Indonesia and Malaysia etc.
Current scenario:
- In the recent past, the situation in Rakhine state has become more volatile increased fighting between Myanmar’s military junta and the Arakan Army over the past year has both caught Rohingya in the middle and seen them targeted.
- UNICEF said that the agency received alarming reports that civilians, particularly children and families, were being targeted or caught in the crossfire, resulting in deaths and severe injuries, making humanitarian access in Rakhine extremely challenging.
Bangladesh’s problem:
- In 2017, Bangladesh opened its borders to Rohingyas leaving Myanmar, eventually allowing more than 700,000 refugees to take shelter in the Muslim-majority nation.
- This was in addition to the more than 300,000 refugees who had already been living in Bangladesh for decades in the wake of waves of previous violences by Myanmar’s military.
- Since 2017, Bangladesh has attempted multiple times to send the refugees back, but with little success.
3. Attacking Hezbollah, Israel fighter jets launch strikes across Lebanon
Sub: IR
Sec: Places in news
Context:
- Israel launched a series of air strikes across Lebanon in what it said was a pre-emptive strike to avert a large Hezbollah attack.
- Israeli Prime Minister also warned that the strikes in Lebanon were “not the final word” in Israel’s military campaign against Hezbollah.
- Soon after, Hezbollah said it had launched an attack on Israeli military positions as an initial response to the killing of a Lebanese military leader in an Israeli air strike.
Heightened tensions:
- Exchange of fire appears to have ended for now and both sides claim to have only targeted military sites.
- Situation remains tense, with potential for further escalation.
Background of the issue:
- On October 8, 2023, a significant escalation in the Israel-Hamas conflict occurred when Hamas launched a large-scale surprise attack on Israel.
- In response, Israel undertook extensive military operations in Gaza, aiming to neutralize Hamas’ capabilities and infrastructure.
- The escalation led to severe humanitarian crisis in Gaza and heightened tensions across the region.
- Hezbollah, a Shiite militant group based in Lebanon, has historically supported Hamas, a Palestinian Islamist organization.
- Hezbollah has provided military support and financial aid to Hamas in the ongoing conflict with Israel.
- While the Lebanese government officially maintains a stance of neutrality, Hezbollah and Israel have exchanged fire along the Lebanon-Israel border.
Peace talks:
- Egypt is hosting high-level talks to broker a ceasefire in the Israel-Hamas war in Gaza.
About Hezbollah:
- Hezbollah is a Shia Islamist political party and militant group based in Lebanon.
- It emerged in the 1980s as a response to the Israeli occupation of southern Lebanon.
- It is designated as a terrorist organisation by several countries, including US and Israel.
- The group is currently involved in Lebanese politics, holding seats in the Parliament and participating in the government.
- It is a part of the axis of resistance grouping.
4. Frequent mass wasting in Tibet a cause for worry in India
Sub: Geo
Sec: Indian Physical geo
Context:
- Mass wasting has increased in the Sedongpu Gully, Tibetan Plateau, since 2017 due to rapid warming.
- A geological event, mass wasting is the gravity-influenced movement of rock and soil down a slope.
- A gully is a landform created by erosion from running water, mass movement or both.
Sedongpu glacier:
- The Sedongpu Gully, in the catchment of the Sedongpu glacier and its valley, is 11 km long and covers 66.8 sq. km.
- It drains into the Yarlung Zangbo, or the Tsangpo River, near where it takes a sharp turn- called the Great Bend– while flowing around Mt. Namcha Barwa (altitude 7,782 metres) and Mt. Gyala Peri (7,294 metres) to create a gorge 505 km long and 6,009 metres deep. This is one of the deepest gorges on the earth.
- The Great Bend is close to Tibet’s border with Arunachal Pradesh, where the Tsangpo flows as the Siang River.
- In Assam further downstream, the Siang meets the Dibang and Lohit to form the Brahmaputra, which flows as the Jamuna in Bangladesh.
River Choking and Flash Floods:
- China plans to set up a 60-gigawatt project on the Tsangpo, which will [have] thrice the capacity of the Three Gorges project on the Yangtze, the world’s largest hydropower plant, raising concerns about river choking and flash floods in downstream areas.
- The Brahmaputra, one of the most sediment-laden rivers, already carries over 800 tonnes of sediment at Pandu in Guwahati, increasing to more than a billion tonnes in Bangladesh.
- Increased sedimentation could worsen flood hazards, cause river channels to choke, and affect livelihoods dependent on fishing.
- More than 700 million cubic metres of debris have been mobilised since 2017 due to warming and earthquakes.
Patterns of Landslides:
- The Sedongpu study analysed 149 satellite images from 1969 to 2023, identifying 19 large mass-wasting events in the gully.
- These events were categorized into ice-rock avalanches (IRA), ice-moraine avalanches (IMA), and glacier debris flows (GDF).
- Debris from IRAs has temporarily blocked the Tsangpo River, leading to catastrophic flash floods downstream, such as those in Arunachal Pradesh and Assam in 2000.
Lull Before Hyperactivity:
- The gully experienced its first mass wasting event from 1974 to 1975, with no catastrophic events until 1987.
- A significant increase in mass wasting events has been observed since 2017, with 13 out of 19 events occurring post-2017, accounting for 68.4% of the total.
- The study notes that the area’s bedrock is mainly Proterozoic marble, with land surface temperatures rarely exceeding 0º C before 2012, but increasing rapidly since then.
Mass Wasting:
- Mass wasting, or mass movement, involves the movement of rock or soil down slopes under the force of gravity.
- It differs from other erosion processes as the debris is not transported by a moving medium like water, wind, or ice.
- Types of mass wasting include creep, solifluction, rockfalls, debris flows, and landslides, each with unique characteristics and varying timescales, from seconds to hundreds of years.
- This process occurs on terrestrial and submarine slopes and has been observed on Earth and other bodies in the Solar System, including Mars, Venus, and Jupiter’s moon Io.

Context:
- Punjab was saved from incurring losses of Rs 2,800 crore due to community nurseries, known as “nursery langars”.
- Despite an additional expenditure of Rs 245 crore by farmers, the community nurseries helped achieve the average rice yield equivalent to 2022 levels.
Nursery Langars Initiative
- The “Nursery Langar” initiative, rooted in Sikh tradition, played a crucial role in saving flood-hit farmers by providing free paddy saplings.
- It provided free nurseries to farmers after floods damaged lands in 2023.
- Volunteers, entrepreneurs, and farmer groups raised nurseries, which were geo-tagged and made accessible to affected farmers through publicized contact information.
- Awareness camps and support from PAU, KVKs, and regional centers helped small and marginal farmers replant short-duration rice varieties like PR 126 and Pusa Basmati 1509.
Economic Impact and Success of the Initiative:
- Farmers incurred additional costs for re-transplantation, including labour, diesel, and weedicide expenses, totalling Rs 245 crore.
- Despite the floods, the average rice yield in Punjab increased by 4%, with the highest yield recorded in Malerkotla district.
- The success of the community nurseries demonstrates their effectiveness as a contingency plan to mitigate the impact of floods, highlighting the broader role they can play in addressing climatic challenges.

6. With hundreds stranded in Sao Paulo, India to broach topic with Brazil Minister Foreign Minister
Subject: IR
Sec: Places in news
Context:
The plight of hundreds of men and women, many of them Indian, who are stranded at an airport in Sao Paulo as they are suspected to be illegal immigrants, maybe discussed during meetings with Brazilian Foreign Minister Mauro Vieira.
More on News:
- Vieira is in New Delhi to hold the 9th India-Brazil Joint Commission meeting with External Affairs Minister S. Jaishankar, and they will also discuss the agenda for the upcoming G-20 summit in Rio De Janeiro on November 18 and 19, 2024.
- The plight of hundreds of men and women, many of them Indian, who are stranded at an airport in Sao Paulo as they are suspected to be illegal immigrants, maybe discussed during meetings with Brazilian Foreign Minister Mauro Vieira.
- With Brazil holding the G-20 Presidency this year, the Ministers will also discuss how the two countries as [part of the] Troika can take forth key G-20 outcomes from the Indian Presidency last year.
- Brazil exports crude oil and cooperates with India on biofuels.
- Although India is a key member of the “Troika” of Brazil, India and South Africa (hosts of 2023, 2024 and 2025 respectively).
- India and Brazil are also both members of the BRICS, IBSA and BASIC groupings as well as part of the G-4 initiative for UN reform and the Ministers are likely to speak about the upcoming UN “Summit of the Future” on September 22-23, that Prime Minister Narendra Modi and Brazil President Lula da Silva are expected to attend.
Brazil’s new regulations:
- To crackdown on illegal immigration routes, and the issue of more than 660 people, including more than 100 Indians being held in Sao Paulo’s Guarulhos Airport for several weeks, are not on the formal agenda, officials expect that they will be raised. “We have seen reports of people stranded who ask to be admitted [to Brazil] as refugees,” while adding that no information has been shared with New Delhi so far due to privacy reasons, and to protect those requesting asylum.
- On August 22, Brazil’s Justice Ministry also announced it would impose new restrictions on travellers from “certain Asian countries” who transit through its airports beginning August 26, and will not allow them to stay on in Brazil.
- The measure is expected to target Indians, Chinese, Nepalis and Vietnamese citizens in particular, who are believed to be part of a growing trend of illegal immigrants landing and requesting asylum, and then taking the land route from Brazil to the Mexican border with the United States in order to cross over to the U.S. and Canada.
- According the U.S. Justice department, the number of such “asylum applications” have increased 61 times between 2013 and 2023, growing from 69 to 4,239, and they were joining hands with other countries in North and South America to restrict the illegal immigration route.
- Evidence suggests that those migrants, in their majority, are making use of the known – and extremely dangerous – route that goes from Sao Paulo to the western state of Acre, so they can access Peru and go toward Central America and then, finally, reach the U.S. from its southern border.
7. Environmental Impact of Lithium Mining in Chile’s Atacama Salt Flat
Sub: Geo
Sec: Eco geo
Why This is in News:
A recent study by researchers at the University of Chile, published in the journal IEEE Transactions on Geoscience and Remote Sensing, has revealed that the Atacama salt flat is sinking due to lithium mining activities. This study highlights the environmental consequences of lithium extraction, a critical issue given the increasing global demand for lithium, especially for use in electric vehicle batteries.
Main Issues:
Lithium Extraction and Subsidence in Atacama
- Study Findings: Researchers found that the Atacama salt flat is sinking by 1 to 2 centimeters annually. This subsidence is primarily occurring in areas where lithium miners are actively extracting lithium-rich brine.
- Mechanism of Sinking: The rapid extraction of brine is outpacing the natural recharge of aquifers, leading to the downward movement of the Earth’s surface.
Environmental Consequences of Lithium Mining
- Water Scarcity: The brine evaporation process, used to extract lithium, consumes vast amounts of freshwater—2,000 tons of water for every ton of lithium produced. This exacerbates water scarcity in the already arid Atacama Desert.
- Ecosystem Contamination: The use of chemicals like sulfuric acid and sodium hydroxide in lithium extraction contaminates the soil and water, threatening local ecosystems and species.
- Biodiversity Loss: A study in 2022 reported a decline in flamingo populations in the Atacama region, linked to reduced water levels caused by extensive lithium mining.
Atacama Desert:
Driest Place on Earth: The Atacama Desert is the driest desert in the world, with some areas receiving less than 1 millimeter of rainfall per year.
Location: It is located in northern Chile, stretching along the Pacific coast between the Andes Mountains and the Chilean Coast Range.
High Altitude: The desert’s elevation ranges from 2,400 meters (7,900 feet) to over 4,500 meters (14,800 feet) above sea level.
Salt Flats: The Atacama Desert is home to the Salar de Atacama, one of the largest salt flats in the world and a major source of lithium.
Unique Flora and Fauna: Despite its arid conditions, the Atacama supports unique plant and animal life adapted to extreme dryness, including the resilient Andean flamingo.
Astronomical Observatories: The desert’s clear skies and high altitude make it an ideal location for astronomical observatories, such as the ALMA (Atacama Large Millimeter/submillimeter Array) telescope.
Lithium:
Rechargeable Batteries: Lithium is a key component in rechargeable batteries used in electronics such as smartphones, laptops, and electric vehicles.
Symbol and Atomic Number: Lithium is represented by the chemical symbol “Li” and has the atomic number 3.
Lithium Reserves: The majority of the world’s lithium reserves are located in the “Lithium Triangle,” which includes parts of Chile, Argentina, and Bolivia.
Lightest Metal: Lithium is the lightest metal and has the lowest density of all solid elements, making it valuable for lightweight battery applications.
Industrial Uses: Beyond batteries, lithium is used in ceramics, glass, and as a heat-resistant lubricant.
Brine Evaporation Method for Lithium Extraction:
Collection: Lithium-rich brine, a saltwater solution containing lithium, is pumped from underground salt flats into large evaporation ponds.
Evaporation: The brine is spread across these ponds to allow water to evaporate naturally under the sun, leaving behind concentrated lithium salts.
Extraction: The concentrated lithium salts are then harvested and processed to obtain lithium carbonate or lithium hydroxide, which are used in batteries and other products.
Environmental Impact: This method requires significant amounts of freshwater for brine preparation and can lead to environmental concerns, including water depletion and soil contamination.

9. U.N. ‘concerned’ by Afghanistan morality law
Subject: IR
Sec: Places in news
Context:
The U.N. mission in Afghanistan was “concerned” about a morality law recently ratified by the Taliban authorities, criticising in particular restrictions on women.
Afghanistan morality law:
- The Taliban authorities announced the codification of a law with 35 articles detailing wide-ranging behaviour and lifestyle restrictions based on their strict interpretation of Islamic law.
- The law sets out graduated punishments for non-compliance – from verbal warnings to threats, fines and detentions of varying lengths – imposed by the morality police under the Ministry for the Propagation of Virtue and the Prevention of Vice.
- It is a distressing vision for Afghanistan’s future, where moral inspectors have discretionary powers to threaten and detain anyone based on broad and sometimes vague lists of infractions.
- After decades of war and in the midst of a terrible humanitarian crisis, the Afghan people deserve much better than being threatened or jailed if they happen to be late for prayers, glance at a member of the opposite sex who is not a family member, or possess a photo of a loved one.
- Many components of the law have already been informally in place since the Taliban returned to power in August 2021.
- Women have borne the brunt of restrictions the N. has labelled “gender apartheid”, which have pushed them from public life.
- The law says women must cover their faces and bodies if they leave the house, as well as ensure their voices are not heard.
- The U.N. also expressed concern over restrictions on religious and press freedoms in the law, which stipulates media must not publish “content hostile to Sharia law and religion” or “that shows living beings”.
10. Long-term monitoring of Himalayan glaciers essential to assess their health
Subject: Geo
Sec: Geomorphology
Context:
Of the estimated 200,000 glaciers in the world, the Himalaya-Karakoram range is home to 39,660. Of these, only 24 have been consistently monitored for their glacier mass balance which indicates whether a glacier is growing or shrinking.
Monitor glacial health:
- It is crucial to monitor glacial health to understand the relationship of glaciers with climate and hydrology in the region.
- But high elevation and challenging atmospheric and climatic conditions make it difficult to monitor.
- Demarcating micro-climatic regions and monitoring a glacier in each of them as a representative of the whole region.
- The Himalaya-Karakoram (HK), a 2,500 kilometre-long mountain range, straddles the border between India in the east and across Bhutan, Nepal, northern India, and Pakistan in the west. This region is home to over 39,660 glaciers, covering 42,525 square kilometres across three river basins: Indus, Ganges and Brahmaputra.
- HK region has a much higher number of glaciers than any other mountain range on Earth.
Formation of glaciers:
- When snow falls and accumulates new layers over time, it gets compressed into large, thick masses of ice, forming glaciers.
- The upper part of the glacier — called the accumulation zone — receives precipitation in the form of snow, which accumulates over time.
- But in the lower part of the glacier — called the ablation zone — there is more melting of the snow and ice than accumulation.
- The balance between the accumulated and melted snow is known as the glacier mass balance, which determines the health of the glacier.
- Glaciers are crucial for downstream communities as they provide drinking water, or water for irrigation.
- Glaciers also regulate river flow and counter global warming.
Need to monitor glaciers:
- To understand how glaciers evolve — if glacier mass is growing, shrinking, or remaining the same — glaciologists say it is important to monitor glaciers on a yearly basis.
- The snow accumulation and the snow melt is measured throughout the hydrological year, to determine the glacier’s health.
- Of Nepal’s glaciers, which fall under the Central Himalayas, less than ten (only seven glaciers) are being monitored. Three of these — Mera glacier, Changri Nup glacier and Pokalde glacier — are located within the Dudh Koshi basin, in Nepal’s Khumbu area, home to Mount Everest.
- Mera glacier has been monitored since 2007 at least once a year (in November).
- Its mass balance series is the longest continuous field-based series in the Central Himalayas and second longest in the entire Hindu Kush Himalayan region.
