Interconnected Disaster Risks report 2023

According to the Interconnected Risks report 2023, world is inching closer to 6 interconnected risk tipping points, describing immediate and increasing risks across the world.

Interconnected Disaster Risks Report

Launched By




Institute for Environment and Human Security (UNU-EHS) is the academic arm of the UN University that is based at Bonn, Germany.

  • Objectives of the report - It analyses several disasters every year and sheds light on the interconnections with each other and with human actions.

Risk tipping point is the moment at which a given socio-ecological system can no longer buffer risks and provide its expected functions. After this point, the risk of catastrophic impacts to these systems increases substantially.

6 Risk Tipping Points

  • Extinctions - In last 100 years, more than 400 vertebrate species were wiped out and a million plant and animal species are at risk of being extinct.
  • About 32 million hectares of primary or recovering forest were lost between 2010 and 2015.
  • Depleting groundwater - 21 of 37 world’s largest aquifers are depleting faster than they can be replenished.

In India, the north-western part is predicted to experience critically low groundwater availability by 2025 and 78% of wells in Punjab were reported as overexploited.

  • Melting glaciers - Melting is at double the speed relative to the past 2 decades risking 1.9 billion people.
  • Around 50% of glaciers (excluding Greenland and Antarctica) would be lost by 2100 irrespective of any current efforts.
  • Space debris - About 75% objects orbiting around earth are junks and around 130 million debris are too small to be tracked.
  • Unbearable heat - High heat with humidity, hinders the sweat evaporations and may cause organ failure and brain damage.
  • Uninsurable future - Increased and severe extreme weather events have complicated the delivery of insurance of damages.
  • Since the 1970s, damages wrought by weather-related disasters have increased sevenfold.

QR codes on Food Products

The Food Safety and Standards Authority of India (FSSAI) has recommended the inclusion of a QR (quick response) code on food products.

  • It shall be a part of front-of-pack labelling (FOPL) warning labels.

Front-of-pack labelling (FOPL) is a mandate of FSSAI since 2019 to alert and educate consumers in making an informed choice

  • Need for QR – India is one of the largest markets of packaged foods in the world owing to increased preferences for it.
  • Pre-packaged foods are often high in fat, salt, and sugar which increases the risk of Non Communicable Diseases (NCD).

QR code is a type of 2D matrix barcode which was invented in 1994, by the Japanese company for labelling automobile parts.

  • ObjectiveAn informed choice will be offered to consumers.
    • To increase accessibility by visually impaired individuals.
    • To ensure access to safe food for all.
    • To reduce the prevalence and risks of NCD.
  • Legal backing
    • The FSSAI’s Food Safety and Standards (Labelling and Display) Regulations, 2020.
    • The Rights of Persons with Disabilities Act, 2016.
  • Significance – It can help improve food manufacturer’s brand image, customer loyalty, and operational efficiency

QR Code Statistics 2022

  • It is released by a private entity QR TIGER.
  • US, India and France are the top 3 nations in usage of QR codes.
  • Among respondents, 57% scanned a food QR code, 38.99% of want to see QR codes and 67% agreed that these codes make life easier.

Cloud Seeding

Recently, Indian Institute of Tropical Meteorology (IITM) based in Pune demonstrated cloud seeding experiment in Solapur city to bring rainfall.

  • Cloud seeding – It is a weather modification technique that improves a cloud’s ability to produce rain or snow.
  • It can be done from ground-based generators or aircraft.

Cloud seeding method was started in 1946 in USA by using silver iodide and dry ice (solid carbon dioxide) to improve the creation of ice crystals in clouds.

  • Working mechanism – A tiny ice nuclei is introduced into certain types of subfreezing clouds.
  • These nuclei provide a base for snowflakes to form which grow and fall from the clouds back to the surface of the Earth.
  • Hygroscopic cloud seeding – It disperses salt particles to speeds up droplet coalescence in liquid clouds to produce of large droplets to start precipitation.
  • Glaciogenic cloud seeding – It disperses ice nuclei to trigger ice production in super cooled clouds, leading to precipitation.


  • Applications – It can create more winter snowfall.
  • It enhances the natural water supply to communities
  • It lessens hailstorms by reordering water vapour in clouds to breakdown large hailstones
  • It is used to tackle air pollution.
    • Central Pollution Control Board (CPCB), India mulled the use of cloud seeding to tackle Delhi’s air pollution.
  • Challenges – The chemicals used in seeding can cause potential side effects to living organisms.
  • It can change climatic patterns of the earth.
  • It involves huge costs and logistics preparations.

Cloud Aerosol Interaction and Precipitation Enhancement Experiment (CAIPEEX phase-4) was a scientific investigation conducted in Solapur city by IITM to investigate the efficacy of hygroscopic seeding in deep convective clouds and to develop a cloud seeding protocol.

Varshadhare Project is a cloud seeding project of Karnataka government to enhance the amount of precipitation from the clouds to generate more rain.

Snow Crab

In recent years, billions of snow crabs have disappeared from the eastern Bering Sea off the coast of Alaska due to marine heatwave that likely caused them to starve to death.

Scientific Name

Chionoecetes opilio

Eye Colour

Green or Greenish Blue

Body Colour

Brownish on top and lighter underneath.


Hard rounded shell.

4 pair of walking legs.

1 pair of claws.

  • Sexual dimorphism – Males and females can be distinguished by the shape of their abdominal flaps which are triangular in males and broadly rounded in females.
  • While males can reach 6 inches, females seldom grow larger than 3 inches in shell width.
  • RangeOff the coast of Alaska in the Bering, Beaufort, and Chukchi Seas.
  • HabitatSoft sandy or Muddy Ocean bottoms, typically in water less than 650 feet deep.
  • Feed – Animals living in the sediment and also scavenge on anything dead they find.
  • Predators – Seals, sea otters, octopi, other crabs, and a wide variety of fishes.
  • Growing Conditions – They are cold-water species.
    • Water temperatures below 2  and up to 12 degrees Celsius.
  • Threat - Warmer ocean water affects their metabolism and increases their caloric needs and this increases their mortality rate.

Developed Countries Emission Trajectories

According to CEEW study, the developed countries which are responsible for 75% of existing carbon emissions in the atmosphere will end up emitting 38% more carbon in 2030.

  • The study ‘Trust and Transparency in Climate Action’ of CEEW shows the emission trajectories of developed nations 

Council on Energy, Environment and Water (CEEW) is one of Asia’s leading not-for-profit policy research institutions and among the world’s top climate think tanks.

  • Increased Emissions by 2030 – Developed countries are projected to emit 3.7 GtCO2e more in 2030.
  • 83% of this overshoot will be by USA, Russia, and the EU.
  • Positive impact of COVID-19 – It contributed a substantial part in the 20% reduction of greenhouse gases by developed countries between 1990 and 2020.
  • Limitations in NDCCurrent estimate would reduce only 36% emission by 2019 levels which falls short of target (43% reduction) to limit global warming to 1.5°C.
  • Lagging in climate target of 2030 – Developed countries would reduce only 11% of emissions by 2030.
    • Only Belarus and Norway seem to meet their targets.
    • Japan and Kazakhstan would miss targets by just 1% point.
  • Inconsistency in net-zero target by 2050Only 5 developed countries are linearly on track to reach net zero by 2050.
  • Most developed countries plans deep emission cuts only after 2030.
  • Even if they attain NZT by 2050, 40-50% of remaining global carbon budget would be consumed by developed countries.
  • Shifting of Burden – The historical and proposed actions of developed countries not show any deep emission reductions.
  • Thus the burden to mitigate global warming shifts to developing countries which lack financial support.
