Century of Change in Indian Villages: Insights from Longitudinal Studies
Context:
The inception of historical surveys in five Tamil Nadu villages in 1916-17 by Gilbert Slater marked the initiation of a century-long exploration of rural India.
Distinct Village Studies: Palakurichi and Palanpur, subjects of extensive study for over a century and decades, respectively, stand out as unique Indian villages.
Methodology and Evolution of Village Studies
Initial Strategy: Slater’s students, natives of the surveyed villages, utilized questionnaires to comprehend the socioeconomic conditions of rural households.
Subsequent Investigations: These villages underwent repeated studies in 1936-37, 1964, 1983, 2004, and 2019, providing a comprehensive longitudinal perspective.
Significance of Longitudinal Studies
Comparison with Cross-Sectional Surveys: In contrast to the cross-sectional surveys conducted by the National Sample Survey Office, village studies are longitudinal, emphasizing in-depth analysis over time.
Objective: The primary goal is to trace changes in the specific village across time, offering micro-level insights complementing macro-level data.
Key Insights from Recent Surveys
Economic Transformations: The 2019 survey of Palakurichi highlighted a reduction in agriculture’s dominance, with only 43.3% of the workforce engaged in farming, a decrease from 85% in 1983.
Diversification of Workforce: Similar shifts were observed in Palanpur, indicating a substantial transition from agriculture to non-farm occupations over the decades.
Evolution of Social Dynamics
Diminished Influence of Traditional Landholders: Both Palakurichi and Palanpur witnessed a decline in the power of traditional upper-caste landholders, with middle castes and Dalits acquiring more land ownership.
Economic and Social Mobility: These changes signify broader social and economic mobility within rural communities.
Policy Implications and Challenges
Land Leasing Practices: As certain communities move away from agriculture, the prevalence of land leasing, often based on oral agreements to circumvent legal complexities, becomes common.
Necessity for Policy Revisions: There is a demand for policies that strike a balance between the interests of landowners and tenant farmers, promoting investment in land improvement.
Sustaining Agricultural Productivity: With rural India decreasing its reliance on agriculture, ensuring the continued or enhanced practice of farming on existing agricultural lands becomes crucial.

Supreme Court rules that tribunals cannot direct government to frame policy
Context
In a recent ruling, the Supreme Court (SC) clarified that tribunals, operating within the confines of their governing legislations, lack the authority to compel the government to formulate policies.
About the Judgment:
- The Supreme Court deliberated on whether the Armed Forces Tribunal (AFT) had the jurisdiction to instruct the government to devise a policy for appointing a Judge Advocate General (Air).
- The AFT possesses the powers of a civil court but does not wield the authority of the Supreme Court or High Courts.
Tribunals Overview:
- Tribunals, quasi-judicial bodies in India, address disputes related to administration, taxation, environment, securities, etc.
- Established as an alternative to traditional courts, tribunals aim for swift, cost-effective, and decentralized dispute resolution.
- Functions include adjudicating disputes, determining rights, making administrative decisions, reviewing existing administrative decisions, and more.
Formation Rationale:
Key features of Indian tribunals include adherence to natural justice principles, exemption from the Civil Procedure Code (CPC), expertise in subject matter, quasi-judicial powers, appellate authority, time-bound resolution, and constitutionality.
Constitutional and Legal Framework:
- The original Constitution lacked tribunal provisions, but the 42nd Amendment Act of 1976 introduced Part XIV-A, covering administrative tribunals (Article 323A) and tribunals for other matters (Article 323B).
The Administrative Tribunals Act, 1985, empowered the Central government to establish tribunals for speedy and inexpensive justice for public servants.
2020 Tribunal Rules:
- The Ministry of Finance introduced the ‘Tribunal, Appellate Tribunal, and other Authorities (Qualifications, Experience and other Conditions of Service of Members) Rules, 2020.’
- Applicable to 19 tribunals, these rules emphasize judicial or legal experience for appointments, a fixed four-year term, and removal powers vested in a “Search cum Selection Committee.”
- Notably, the 2020 Rules address issues raised by the Supreme Court regarding the earlier 2017 Rules.
Tribunal Restrictions:
- Jurisdiction is specific to areas like employment, tax, environment, and administrative law, derived from governing statutes.
Tribunals are bound by procedural rules, with limited appellate jurisdiction and a defined appeal mechanism to ensure fairness and prevent exceeding statutory authority.

Delhi Fog
Context:
Delhi recently experienced its most intense fog cover of the winter, causing visibility to plummet to zero meters at the Indira Gandhi International Airport and disrupting flight operations.
About:
- Fog occurs when air near or at the Earth’s surface becomes saturated through processes like cooling, moisture addition, or mixing with another air parcel.
- It typically forms in a stable air mass environment and is unlikely in an unstable atmosphere due to convective or layered cloudiness resulting from vertical mixing.
There are several types of fog, including:
- Radiation Fog: Forms when solar energy exits the Earth, allowing temperatures to meet the dew point. Ideal conditions involve previous night rainfall, moistening the soil and raising dew points. Light winds (less than 15 mph) prevent the mixing of moist and dry air.
2. Precipitation Fog: Occurs when rain falls through cold air, common with warm fronts but possible with slow-moving cold fronts. Cold, dry air at the surface causes rain to evaporate, raising the dew point and forming fog.
- Advection Fog: Develops through horizontal wind contact with the surface, often in windy conditions. Warm, moist air from the south interacts with snow or cool moisture on the ground, leading to cooling, rising dew points, and fog formation.
- Steam Fog: Common in the Great Lakes and other lakes during the fall. Dry, cold air moves over warmer lakes, conducting warm, moist air into the air mass above, resulting in steam fog that doesn’t become very deep but can block sunlight.
- Upslope Fog: Forms adiabatically as moist winds blow toward a mountain, causing upgliding, air rising, and cooling. Cooling air meets the dew point, leading to fog on mountaintops.
- Valley Fog: Forms in valleys when the soil is moist from previous rainfall. Clearing skies allow solar energy to exit the Earth, cooling temperatures near or at the dew point and forming dense fog, sometimes referred to as tule fog.
- Freezing Fog: Occurs when the temperature falls to 32°F (0°C) or below, producing drizzle that freezes upon contact with objects.
- Ice Fog: Seen only in polar and arctic regions, where temperatures at 14°F (-10°C) are too cold for super-cooled water droplets, leading to the formation of small ice crystals.
Related concepts:
- Mist and Fog: Both result from water droplets in the air, with fog denser than mist. Fog is officially recognized as visibility less than 1,000 meters, while mist refers to droplets not reducing horizontal visibility to less than 1 kilometer.
- Haze: Arises from sunlight reflecting off dry pollutant particles in the air, often occurring far from the pollution source due to wind currents.
- Smog: Contains ozone and forms when sunlight reacts with nitrogen oxides and volatile organic compounds in the atmosphere, originating from sources like car exhaust and industrial emissions.
Vog: Specific to volcanic activity, it results from sulfur dioxide released during eruptions reacting with other gases in the air, forming a fog-like haze.
