  3. Japan’s Alternatives and Expert Opinions on Fukushima Water Disposal

Fukushima Nuclear Disaster: Timeline and Impact

  • March 2011: A powerful magnitude 9 earthquake strikes, followed by a tsunami that inundates the Fukushima Daiichi nuclear power plant in Okuma.
  • Diesel generators are damaged, leading to a loss of power and cooling systems failure for the reactors.
  • The absence of cooling triggers reactor meltdowns and explosions due to the build-up of pressure and heat.
  • Radioactive materials are released, contaminating air, water, soil, and the local population.
  • Winds disperse radioactive particles into the Pacific Ocean.
  • The area around the power plant becomes uninhabitable and remains so, rendering the facility and its surroundings unusable.

Japanese Government’s Water Disposal Plan and Opposition

Government’s Intentions:
  • The Japanese government aims to release water from the Fukushima nuclear plant that was used to cool reactors, along with rainwater and groundwater.
  • This water contains radioactive isotopes from damaged reactors and was crucial for cooling purposes.
  • The plan involves treating the water to remove most radioactive elements before releasing it into the Pacific Ocean over a span of 30 years.
  • Such water releases are common practice in nuclear plants globally after treating to meet safety standards.
Reasons for Opposition:
  • Critics argue that no radiation exposure can be considered entirely safe, challenging the claim that the treated water will be harmless.
  • Experts warn that any discharge of radioactive substances into the ocean could heighten cancer risks and other health consequences for exposed populations.
  • Tritium, a challenging isotope to remove from the water, is a particular concern. It is easily absorbed by organisms and distributed via blood circulation.
  • Concerns also surround potential contamination of aquatic life, especially fish, impacting ecosystems and seafood industry.
  • Countries like South Korea, China, Taiwan, and Pacific Islands Forum have voiced objections to the plan, reflecting broader regional concerns.
  • Calls for comprehensive studies on water tank contents before discharge are being made by researchers worldwide.

Japan’s Alternatives and Expert Opinions on Fukushima Water Disposal

Alternative Options for Japan:
  • One alternative for Japan is to store the contaminated water for an extended period before considering discharge.
  • Tritium’s half-life is around 12-13 years, meaning its radioactivity will naturally decrease over time.
  • Similarly, other radioactive isotopes’ levels will also decrease during this period, potentially leading to less radioactive water upon eventual discharge.
Expert Perspectives:
  • The International Atomic Energy Agency (IAEA) released a report in July affirming that if the discharge is carried out as planned, it will have minimal environmental and human health impact.
  • Many scientists support the IAEA’s stance on the matter.
  • However, some experts highlight the need to study the potential long-term consequences of low-dose radioactivity that might persist in the discharged water.

Production Linked Incentive Scheme


Recently, a debate has emerged over the effectiveness of India’s Production-Linked Incentive (PLI), an Electronics Manufacturing scheme, suggesting it generates import-dependent assembly jobs rather than fostering Self-Sufficiency in manufacturing and economic growth.


GS III: Indian Economy

Dimensions of the Article:

  1. Promoting Domestic Manufacturing: The Production Linked Incentive Scheme (PLI)
  2. Challenges and Concerns Surrounding the PLI Scheme

Promoting Domestic Manufacturing: The Production Linked Incentive Scheme (PLI)

  • The Production Linked Incentive (PLI) scheme was devised to bolster domestic manufacturing capacity, foster import substitution, and drive employment generation.
  • Initiated in March 2020, the scheme initially targeted three sectors, including Mobile and Allied Component Manufacturing, Electrical Component Manufacturing, and Medical Devices. Later, it was expanded to encompass 14 diverse sectors.
Participation and Rewards:
  • The PLI scheme extends rewards to both domestic and foreign companies engaged in manufacturing within India.
  • The rewards are based on a percentage of their revenue over a maximum period of five years.
Scope of Sectors:
  • The 14 sectors covered by the scheme include mobile manufacturing, medical device production, automobile and auto components, pharmaceuticals, specialty steel, telecom and networking products, electronic products, white goods (ACs and LEDs), food products, textile products, solar PV modules, advanced chemistry cell (ACC) batteries, and drones along with drone components.
Incentive Calculation:
  • The incentives provided are calculated with reference to incremental sales.
  • For sectors like advanced chemistry cell batteries, textiles, and the drone industry, the calculation incorporates factors such as sales performance, local value addition, and sales growth over a five-year span.
Fostering Research and Development:
  • A key emphasis of the scheme lies in encouraging investment in research and development.
  • This approach ensures that industries remain aligned with global trends and maintain competitiveness in the international marketplace.
Achievements in Smartphone Manufacturing:
  • The PLI scheme’s effectiveness is evident in the smartphone manufacturing sector.
  • In FY 2017-18, mobile phone imports totaled USD 3.6 billion, with exports at a mere USD 334 million, leading to a trade deficit of -USD 3.3 billion.
  • However, by FY 2022-23, imports decreased to USD 1.6 billion, while exports surged to almost USD 11 billion, yielding a positive net export value of USD 9.8 billion.
  • This stands as a testament to the scheme’s role in reducing trade deficits and enhancing India’s manufacturing and export capabilities.

Challenges and Concerns Surrounding the PLI Scheme

Limited Value Addition in Mobile Manufacturing:

  • Subsidies in the Mobile and Allied Component Manufacturing sector are provided based solely on phone assembly in India, rather than on the value added through domestic manufacturing.
  • This has led to the import of numerous components for mobile phones, including display screens, cameras, batteries, and printed circuit boards.
  • Despite a surge in mobile phone exports, much of the value addition remains outside India.

WTO Limitations on Subsidies:

  • WTO regulations prevent India from tying PLI subsidies to domestic value addition, hindering efforts to encourage higher value-added activities.
  • While India aims to manufacture complex components like chips, this aspiration faces challenges due to the complexity involved.

Lack of Clarity in Incentive Allocation:

  • The Empowered Committee responsible for overseeing the PLI scheme and distributing funds lacks clear guidelines for awarding incentives.
  • Ministries and departments lack standardized criteria for determining incentive allocation, raising concerns about the fairness and effectiveness of the scheme.

Absence of Comprehensive Data:

  • The absence of a centralized database capturing metrics such as production increase, exports, and job creation complicates the evaluation process.
  • This data gap creates administrative complexities and undermines transparency, potentially leading to mismanagement and weakening the integrity of the policy framework.

The Fujiwhara effect


The United States west coast recently witnessed Hurricane Hilary (a sub-tropical storm by the time it hit the US), prompting the National Hurricane Centre (NHC) to issue its first ever tropical storm watch for parts of Southern California. This was the latest incident in a string of unusual weather phenomena in the region.

  • In one of these storms, two small areas of low pressure were drawn together in a ‘dance’: instead of merging together, the stronger low pressure area became the dominant one in the system – displaying, for a brief moment, what is known as the ‘Fujiwhara effect’.


GS I: Geography

Dimensions of the Article:

  1. Fujiwhara Effect
  2. Impact and Increasing Occurrence of Fujiwhara Effect

Fujiwhara Effect:

  • The Fujiwhara effect refers to the phenomenon in which two cyclones (hurricanes or typhoons) that are spinning in the same direction come close to each other and engage in an intricate dance around a common center of rotation.
  • Interaction and Outcomes:
  • When two cyclones approach each other closely, their interaction can lead to distinct outcomes based on their relative intensities.
  • If one cyclone is more powerful, it can dominate and absorb the smaller cyclone into its vortex.
  • In cases where cyclones are of similar strengths, they might orbit around a shared center, and their paths could merge temporarily or lead to separate trajectories.
Mega Cyclone Formation:
  • In rare situations, if both cyclones are sufficiently intense, they might merge, resulting in the formation of a single, more powerful cyclone. This mega cyclone can pose a serious threat to coastal areas.
Origins and Discovery:
  • The Fujiwhara effect is named after Sakuhei Fujiwhara, a Japanese meteorologist.
  • It was first mentioned in a paper published in 1921 by Fujiwhara.
  • The phenomenon was observed in 1964 when Typhoons Marie and Kathy merged over the western Pacific Ocean.

Impact and Increasing Occurrence of Fujiwhara Effect:

Effects of the ‘Dance’:
  • The Fujiwhara effect can lead to powerful winds and weather disturbances, as observed in different incidents around the world.
  • In March 2023, the Bay Area and parts of California experienced strong winds causing damage to property and disruptions to power supply.
  • The effect contributed to peak gusts of up to 60 to 75 mph in the Santa Cruz Mountains and 50 to 60 mph winds across Santa Cruz and Santa Clara counties.
  • The interaction of cyclones can lead to the merging of systems or intensification of primary circulation due to the influx of heat, moisture, and vorticity.
Instances and Climate Impact:
  • In 2022, typhoon Hinnamnor and tropical storm Gardo engaged in the Fujiwhara effect, with Gardo being absorbed by Hinnamnor. This led to heavy rainfall and casualties in South Korea.
  • Similar interactions were observed in the past, such as hurricanes Hilary and Irwin in 2017, which merged over the eastern Pacific Ocean.
  • Experts point out that the Fujiwhara effect is becoming more frequent, attributed to a warming climate and increasing ocean temperatures.
  • Rising ocean temperatures contribute to the intensification of cyclones, making them more powerful and increasing the chances of such interactions.
  • The occurrence of the Fujiwhara effect adds complexity to cyclone prediction, as each interaction is unique and challenging to forecast within current climate models.
Climate Change Connection:
  • Climate researchers highlight the connection between the Fujiwhara effect and climate change, particularly the warming of the world’s oceans.
  • Rising ocean temperatures lead to stronger cyclones, creating conditions conducive to the Fujiwhara effect.
  • Ravi Shankar Pandey, a research scholar, noted a 35% increase in the strength of typhoons hitting Taiwan between 1977 and 2016, linked to a rise in sea surface temperatures.
  • The effect reflects the broader impact of a warming climate on extreme weather events and atmospheric dynamics.
