What is Land Subsidence?
Uttarakhand, already battered by natural calamities including cloudbursts, flash floods, and landslides across its mountainous regions, is now facing a new and terrifying phenomenon: widespread land subsidence in Chamoli’s Nanda Nagar.

About Land Subsidence:

  • Land subsidence is a gradual settling or sudden sinking of the Earth’s surface.
  • This geotechnical phenomenon occurs when the ground loses its ability to support the weight above it, leading to a downward shift.
  • It can occur as a result of natural factors (e.g., volcanic or seismic activity, collapse of subsurface cavities, compaction of loose fine-grained deposits) or anthropogenic activities (e.g., excessive groundwater (GW) abstraction, mining, subsurface energy extraction).
  • Although it is a gradual process, taking years to decades to develop, land subsidence presents serious socioeconomic, environmental, and security challenges globally.
  • Impacts:
    • Land subsidence can cause damage to infrastructure and lead to increased flood risks and permanent reduction in aquifers' storage capacity.
    • It can also cause disturbance to water management and possible repercussions such as increased saltwater intrusion as a result of reduction in land elevation and changes in the gradient of streams and drains.
    • High maintenance costs for roads, railways, pipelines, and buildings are only a few examples of stresses brought upon by land subsidence.
  • Although land subsidence has been historically observed in low deltaic areas or coastal regions, it is being increasingly observed in large inland areas near densely urban, agricultural, and industrial areas with high groundwater demand.
  • Excess groundwater extraction is believed to be one of the main causes of large-scale and high-magnitude land subsidence.
    • Groundwater overexploitation compacts the underground reservoirs because water is the element partly responsible for holding up the ground.
    • The excess water withdrawal leads to compaction of the underlying depleted porous formation, thus inducing land subsidence.
  • The total global extent of land surface susceptible to subsidence has been estimated to be 12 million sq.km.
  • Land subsidence has been observed all around the world, with major sites in the USA, China, Iran, Indonesia, Taiwan, Vietnam, Egypt, Japan, Mexico, and Italy.

Global Peace Index (GPI) 2025
Iceland has once again secured its position as the most peaceful country in the world, as per the 2025 Global Peace Index (GPI).
current affairs image

About Global Peace Index (GPI):

  • Produced by the Institute for Economics & Peace (IEP), the GPI is the world’s leading measure of global peacefulness.
  • It ranks 163 independent states and territories according to their level of peacefulness, covering 99.7 percent of the world’s population.
  • It uses 23 qualitative and quantitative indicators to measure the state of peace across three domains: the level of Societal Safety and Security; the extent of Ongoing Domestic and International Conflict; and the degree of Militarisation.
  • Highlights of GPI 2025:
    • It is the 19th edition of the GPI.
    • It finds that global peacefulness continues to decline and that many of the leading factors that precede major conflicts are higher than they have been since the end of WWII.
    • More countries are increasing their levels of militarisation.
    • There are currently 59 active state-based conflicts, the most since the end of WWII and three more than the prior year.
    • Last year, 17 countries recorded over 1,000 conflict deaths.
    • Additionally, the successful resolution of conflicts is lower than at any point in the last 50 years.
    • Conflicts that ended in a decisive victory fell from 49 percent in the 1970s to nine percent in the 2010s, while conflicts that ended through peace agreements fell from 23 percent to four percent over the same period.
    • This year’s results found that the average level of global peacefulness deteriorated by 0.36 percent.
    • Iceland remains the most peaceful country in the world, a position it has held since 2008. It is joined at the top of the index by Ireland, Austria, New Zealand, and Switzerland.
    • Russia, for the first time, is the least peaceful country in the world on the 2025 GPI, followed by Ukraine, Sudan, Democratic Republic of the Congo, and Yemen.
    • Western and Central Europe is the most peaceful region in the world, home to eight of the ten most peaceful countries, although its peacefulness has been falling over the last four years.
    • South America was the only region in the world to record an improvement in peacefulness last year.
    • The Middle East and North Africa (MENA) region remains the world’s least peaceful region.
    • South Asia, the second least peaceful region globally, experienced the largest regional decline in peacefulness.
    • India was ranked 115 on the GPI 2025, up one position from its 2024 spot.
    • The most peaceful Asian countries were Singapore (6th), Japan (12th), Malaysia (13th), Bhutan (21st), and Mongolia (37th).

Incentive Scheme to Promote Critical Mineral Recycling
The Union Cabinet recently approved a Rs.1,500 crore Incentive Scheme to develop recycling capacity in the country for the separation and production of critical minerals from secondary sources.
current affairs image

About Incentive Scheme to Promote Critical Mineral Recycling:

  • It is part of the National Critical Mineral Mission (NCMM), which is aimed at building the domestic capacity of and supply chain resilience in critical minerals.
  • The Scheme will have a tenure of six years from Financial Year 2025-26 to Financial Year 2030-31.
  • Total Outlay: Rs.1,500 crore
  • Features:
    • Eligible feedstock is e-waste, Lithium Ion Battery (LIB) scrap, and scrap other than e-waste and LIB scraps.
    • Expected beneficiaries will be both large, established recyclers, as well as small, new recyclers (including start-ups), for whom one-third of the scheme outlay has been earmarked.
    • The Scheme will be applicable to investments in new units as well as expansion of capacity and modernization and diversification of existing units.
    • The Scheme will provide incentive for the recycling value chain, which is involved in the actual extraction of critical minerals, and not the value chain involved in only black mass production.
    • The incentives include a 20% capital subsidy on plant and machinery for projects that commence production within the stipulated timeframe and an operational subsidy tied to incremental sales.
    • The operational support will be provided in tranches—40% in the second year and 60% in the fifth year—on meeting specific sales thresholds.
    • To ensure wider participation, the total incentive has been capped at ₹50 crore per large entity and ₹25 crore per small entity, with limits on operating subsidies of ₹10 crore and ₹5 crore, respectively.
  • The Scheme incentives are expected to develop at least 270 kilotons of annual recycling capacity, resulting in around 40 kilotons annual critical mineral production, bringing in about Rs.8,000 crore of investment, and creating close to 70,000 direct and indirect jobs.

About Senna spectabilis:

  • It is an invasive species native to tropical America.
  • Common names: Popcorn Bush Cedar, Archibald's Cassia, Calceolaria Cassia, Golden Shower, Scented Shower, Fetid Cassia.
  • It forms dense, sterile thickets, choking out native plants, altering soil chemistry and depriving herbivores of food.
  • It is a tree with a very dense, spreading crown; it can grow 7 - 18 metres tall.
  • It is often planted for fuelwood, as an ornamental, and as a shade tree in agroforestry situations.
  • It resembles Kerala’s state flower Cassia fistula, known locally as 
  • It is classified as Least Concern under the IUCN Red List.
  • Challenges: It has very aggressive growth rate and degrade lands in forest ecosystems which make it challenging to control its spread. 

What are Invasive Species?

  • An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native.
  • These can be introduced to a new area via the ballast water of oceangoing ships, releases of aquaculture species, aquarium specimens, and other means.
