Vanniyar quota

Part of: Prelims and GS II – Policies and interventions 

Context: The Supreme Court has confirmed that the grant of 10.5% internal reservation to Vanniyakula Kshatriya community violates the fundamental rights of equality, non-discrimination and equal opportunity of 115 other most backward communities (MBCs) and de-notified communities (DNCs) in Tamil Nadu.

POLITY/ SECURITY

Assam-Meghalaya boundary dispute resolution

Context: Two months after signing a draft resolution on January 29, Assam and Meghalaya partially resolved a 50-year-old dispute along their 884.9 km boundary. 

How did the boundary dispute start? 

How did the two governments go about handling the issue? 

How was the ice broken? 

Will the partial settlement impact border disputes elsewhere in the Northeast?

AGRICULTURE/ GOVERNANCE

Decarbonising Indian agriculture

Context: In 2016, agriculture and livestock emitted 407,821 Gg of CO2e, around 14% of total emissions. Out of this, 61.3% is linked to livestock. 

Apart from livestock, the major constituents of agriculture GHG emissions are 

Why decarbonisation of Agriculture is a tricky issue in India?

What pathways can be used for decarbonising agriculture?

Deep decarbonising pathways would include 

The following factors are critical for both decarbonisation and sustainability:

Soil
  • Fertile soil enhances farm yields and incomes apart from being a carbon sink. 
  • Healthy soil holds more moisture and soil conservation methods reduce erosion. 
  • The co-products of biogas/biofuels plants are compost/bio-char, which enrich soil, mitigate environment pollution, and displace chemical fertilisers
Freshwater
  • Agriculture consumes over 80% of freshwater in India, making conservation critical. 
  • Micro-irrigation with automation and adoption of low water-intensive species and farming practices is essential. 
  • Areas under water intensive crops must be reduced through crops diversification, examples being oil seeds, pulses, horticulture, and forage crops.
Alternate cropping:
  • This contributes to GHG mitigation and is an emerging area in climate-smart farming. 
  • For example, seaweed cultivation as additive to cattle feed reduces biogenic methane emissions, improves feed quality, and enhances milk production
Agro-forestry:
  • Trees act as windbreaks, reduce soil erosion, enrich soil, and filter water. 
  • Studies suggest that 5% increase at 5 yearly intervals to the existing 16 mha area can help mitigate India’s projected emissions.
Bio-energy from farm waste
  • Manure-based community biogas plants can support clean cooking and distributed power. 
  • India’s National Policy for Biofuels/ SATAT scheme set a medium-term target of 15 million tonnes of bio-CNG. 
  • BECCS (Bio Energy with Carbon Capture & Storage) involves capturing CO2 from bioenergy plants and permanent storage. This will lead to carbon removal as well as negative emissions.
