Steps for Implementing Land Reforms in India

Source: The Hindu

UPSC Daily Current Affairs: 16 August 2024 | Current Affairs & Hindu Analysis: Daily, Weekly & Monthly

Why in news?

The Centre has decided to provide states with Rs 10,000 crore in incentives for implementing land-related reforms in rural and urban areas, and Rs 5,000 crore for creating a Farmers' Registry during the financial year 2024-25 (FY25). The funds will be provided under the Scheme for Special Assistance to States for Capital Investment 2024-25.

Promises Related to the Land Reforms Made in the Union Budget 2024-2025

Land-related reforms in the rural areas:

  • Assignment of unique land parcel identification numbers (ULPIN) or Bhu-Aadhaar for all lands
  • Digitisation of cadastral maps
  • Survey of map subdivisions as per current ownership
  • Establishment of land registry, and linking to the farmers registry

Land-related reforms on the urban front:

  • Digitisation of land records with GIS mapping
  • Establishing an IT-based system for property record administration, updating, and tax administration

Implementation of the Digital Public Infrastructure (DPI) in agriculture

  • The Indian government (in partnership with States) will facilitate the implementation of the DPI in agriculture for coverage of farmers and their lands in 3 years.
  • This programme will include a "digital survey" of the kharif crop in 400 districts and the land details being brought into a.

Significance of Actions on Reforms around Land

  • It points towards a recognition that States are the key actors on these issues, and that approaches and constraints can vary across States. Recognizes importance of States as key actors.
  • Overall better land registries and cadastral maps are key to understanding land-use around the country, to enforce building codes, and to evaluate the risks due to various hazards, including natural disasters. Emphasizes the importance of improved land registries and maps.

Challenges Towards Implementing Actions on Land Reforms

  • India has been trying to develop such land maps since the 1980s, with limited success.
  • One particular pitfall has been a lack of standards.
  • These maps have been made by manual digitisation and are not properly georeferenced, i.e. the digital data is not mapped to fixed geographical coordinates.
  • The States have used different mapping projections, so maps prepared by one State's processes are not directly compatible with those of another.
  • Thus, it is important to develop GIS data standards and interoperability for various end applications first.

Scheme for Special Assistance to States for Capital Investment 2024-25

  • In view of a higher multiplier effect of capital expenditure and to provide a boost to capital spending by States, the scheme was announced in the Union Budget 2024-25.
  • The scheme (first launched in 2020-21) provides financial assistance to state governments in the form of 50-year interest-free loans for capital investment projects.
  • In 2024-25, the scheme was redesigned with an overall allocation of ₹1.30 lakh crore.

3. Algorithmic Bias: 

  • AI systems can perpetuate existing biases present in the data they are trained on, resulting in discriminatory outcomes.
  • For example, Amazon discontinued a recruiting algorithm that exhibited gender bias.

Conflict Between Purpose and Profit

1. Conflict Between Purpose and Profit: 

  • Many companies, like OpenAI, initially adopted governance structures aimed at public benefit but encountered challenges when profit motives conflicted with their social objectives.
  • The dismissal of CEO Sam Altman over concerns of prioritizing commercialization over user safety exemplifies this conflict.

2. Shareholder Primacy: 

  • Despite alternative governance models being adopted, the underlying shareholder primacy often prevails.
  • The pressure to generate profits can overshadow the intended social benefits, making public good secondary to financial gains.

3. Corporate Governance issue: 

  • Governance issues faced by OpenAI, especially the internal conflict leading to Altman's firing, raise questions about the effectiveness of public benefit corporate structures in balancing profit and purpose.
  • This is especially pertinent in tech companies reliant on investor capital.

4. Potential Shift to For-Profit Structures: 

  • Rumors about OpenAI contemplating a transition to a for-profit governance model indicate a trend where companies may abandon their social objectives in favor of profit maximization.

Workable Strategy (Way forward)

  • Framing Ethical Standards: Developing comprehensive ethical guidelines for AI product companies is crucial to ensure responsible and equitable development of AI technologies.
  • Incentivizing Public Benefit Objectives: Corporations should be incentivized to adopt public benefit purposes aligning with their business strategies, potentially involving financial incentives for companies demonstrating long-term profit gains from socially responsible practices.
  • Reducing Compliance Costs: To promote adherence to public benefit objectives, it is essential to lower compliance costs associated with implementing ethical practices.

WHO declares monkeypox a public health emergency of global concern

Source: Indian Express

UPSC Daily Current Affairs: 16 August 2024 | Current Affairs & Hindu Analysis: Daily, Weekly & Monthly

Why in news?

The World Health Organization (WHO) has declared monkeypox a public health emergency of global concern, with a notable impact on the Democratic Republic of the Congo and other African nations. Since 2022, there have been a total of 99,176 reported cases and 208 fatalities across 116 countries. Of particular worry is the emergence of a new strain of the virus that can be transmitted sexually.

World Health Organisation

  • Established in 1948, the WHO is a United Nations agency dedicated to global public health, boasting 194 member states.
  • Headquartered in Geneva, Switzerland, the organization conducts vaccination campaigns, manages health crises, and aids countries in primary healthcare.
  • Funding for the WHO comes from member contributions based on economic status and population, as well as voluntary donations.

India & WHO:

  • India joined the WHO in January 1948 and is part of the South East Asia Region within the WHO.
  • Dr. Chandra Mani, an Indian, served as the first regional director for South East Asia from 1948 to 1968.
  • Currently, Dr. Poonam Khetrapal Singh, another Indian, has held the position since 2014.
  • Dr. Soumya Swaminathan served as the WHO's chief scientist from 2019 to 2022.
  • A PHEIC is declared for an extraordinary event posing a public health risk to other nations through the global spread of disease.
  • The WHO's PHEIC declaration aims to prompt a coordinated international response and potentially unlock funding for collaborative efforts in vaccine and treatment sharing.

Monkeypox

  • Monkeypox is a rare viral disease of zoonotic origin within the Orthopoxvirus genus of the Poxviridae family, the same family as smallpox.
  • Zoonotic diseases are those that transfer from animals to humans.
  • Initially discovered in animals in 1958 during outbreaks in research monkey colonies, hence its name 'monkeypox'.
  • Treatment options for monkeypox are currently limited, but the Vaccinia vaccine, previously used against smallpox, has shown 85% efficacy in preventing monkeypox.

Concerns and Spread

  • A sexually transmissible strain, clade Ib of the monkeypox virus (MPXV), is causing alarm due to its potential for transmission through sexual contact.
  • Historically, clade I infections, more severe than clade II, primarily spread through zoonotic events.
  • However, sexual transmission of clade I was previously unreported.
  • Over 100 cases of clade Ib have surfaced in neighboring countries of the DRC—Burundi, Kenya, Rwanda, and Uganda—where monkeypox was not previously prevalent.
  • Recent developments, including a surge in total monkeypox cases to over 15,600 with 537 deaths this year, highlight the urgent need for an international response.
  • WHO Director-General Dr. Tedros stressed the importance of controlling these outbreaks, as the virus is now transmitting between humans and evolving rapidly into new strains.
  • The first case of the more contagious clade Ib monkeypox infection outside Africa was reported in Sweden, raising concerns about global spread through travel.
  • During the 2022 outbreak,India reported 27 cases and one fatality, primarily from the less severe clade II, initially linked to international travel but later spreading locally.
  • Experts underscore the global emergency posed by the current spike in monkeypox cases in Africa and the spread of a new sexually transmissible strain.

Why climate change poses an existential threat to Panama Canal?

Source: Indian Express

UPSC Daily Current Affairs: 16 August 2024 | Current Affairs & Hindu Analysis: Daily, Weekly & Monthly

Why in News?

The Panama Canal, which links the Atlantic and Pacific Oceans through the Isthmus of Panama, opened to ships 110 years ago. Now, it is facing a serious threat to its existence.

System of Water Elevators

  • The Panama Canal utilizes a sophisticated lock system that functions as water elevators, allowing ships to navigate the elevation difference between the Atlantic and Pacific Oceans.
  • This system is essential because the two oceans are at different elevations, with the Pacific being slightly higher.

Operation of the Locks

Ship Enters:

  • A ship approaches the first lock chamber, which is at sea level.
  • The gate opens to allow the ship into the chamber and then closes behind it.

Water Level Adjustment:

  • The valve between the first and second chamber (at a higher elevation) is opened, allowing water to flow into the first chamber from the adjacent higher chamber.
  • This increases the water level in the first chamber.

Transition:

  • Once the water levels between the two chambers are equalized, the gate between them opens, allowing the ship to move into the next chamber. This process is repeated until the ship reaches the desired elevation of 85 feet at Gatun Lake.

Lowering:

  • The reverse process occurs when lowering ships back to sea level at the other end of the canal.

Threat of Climate Change

  • Recent droughts have led to significantly lower water levels in the canal because droughts were exacerbated by climate change and the El Niño phenomenon, which have led to significantly reduced water levels in the lake.
  • In 2023, rainfall was 43% lower than average, making it one of the driest years on record for the region, which reduced the number of ships able to transit the canal.
  • In December, traffic dropped to as low as 22 ships per day, highlighting the vulnerability of the canal to climatic variations.

Contentious Solution

  • Proposed Dam: A $1.6 billion project aims to create an additional water source for the canal on the Rio Indio, potentially securing water availability for the next 50 years.
  • Displacement Issues: The dam would flood the homes of approximately 2,000 residents, predominantly from lower socio-economic backgrounds, forcing them to relocate and lose their livelihoods. This raises significant ethical concerns regarding the balance between infrastructure needs and the rights of affected communities.

Conclusion

  • Before proceeding with the Rio Indio dam project, engage in thorough consultations with the affected communities, ensuring their voices are heard in the decision-making process. Need to develop a fair compensation and resettlement plan that prioritizes the socio-economic well-being of displaced residents, offering alternative livelihoods and housing options to minimize the negative impact on vulnerable populations.

Do you know about another elevation-based canal system?

  • Kiel Canal (Germany): The Kiel Canal features locks that raise and lower vessels to navigate the elevation differences between the North Sea and the Baltic Sea. It is one of the busiest artificial waterways in the world.
  • Welland Canal (Canada): This canal connects Lake Ontario and Lake Erie and includes a series of locks that lift ships approximately 43 meters (141 feet) to bypass Niagara Falls. It is an essential part of the Great Lakes shipping route.

Trade from Panama Canal

  • The Panama Canal moves roughly $270 billion worth of cargo annually, which is the trade route taken by 40% of all U.S. container traffic alone. It handles about 5% of all global maritime trade.

Mains PYQ

  • Mention the significance of straits and isthmus in international trade. (UPSC IAS/2022)

Indian Astronomers discover new method for Solar Cycle Amplitude Prediction

Source: The Hindu

UPSC Daily Current Affairs: 16 August 2024 | Current Affairs & Hindu Analysis: Daily, Weekly & Monthly

Why in news?

Astronomers from the Indian Institute of Astrophysics (IIA) have developed a new method to predict the amplitude of the upcoming solar cycle. This discovery is based on 100 years of solar data from the IIA’s Kodaikanal Solar Observatory.

What is Space Weather?
  • Space weather refers to the varying conditions within the solar system and its heliosphere influenced by the Sun and solar wind.
  • The main components of space weather include coronal mass ejections and solar flares.
  • These components can compress the Earth’s magnetosphere, triggering geomagnetic storms.
  • This can disrupt communication, power transmission, damage spacecraft electronics, and pose threats to astronauts.
Solar Cycle and Its Importance
  • The activity of the Sun follows an approximately 11-year periodic cycle, marked by variations in the number of sunspots on the Sun’s surface.
  • Solar cycle influences space weather, Earth’s atmosphere, and climate variations.
  • Predicting the amplitude of the solar cycle is a major challenge in astrophysics, as it directly affects related phenomena and space weather.
Research Findings
  • IIA researchers discovered that the width of supergranular cells on the solar surface during the minimum year of the solar cycle correlated with the number of sunspots observed during the subsequent solar cycle maximum.
  • This simple method can be used to predict the strength of the upcoming solar cycle, which is valuable for space weather forecasting.
What are Supergranular Cells? 
  • Supergranular Cells are large convective cells on the Sun’s surface, with diameters of about 30,000 km.
  • These cells are part of the solar convection zone where hot plasma rises, cools as it reaches the surface, and then sinks back down - a continuous cycle.
  • Characteristics: 
    • Supergranular cells are larger than granules, another type of convective cell on the Sun.
    • Its borders, known as supergranular lanes, are about 5,000 km thick.
    • Plasma within these cells moves from the center of the cell toward the edges, where it sinks back into the Sun’s interior, creating a network of lanes on the solar surface.
    • Associated with the magnetic field concentrations on the Sun’s surface, often where sunspots and other magnetic features appear.
