Why This Topic Matters  

Grasslands are among India’s most misunderstood ecosystems—long labelled as “wastelands” and subjected to misguided afforestation drives. This article shifts the narrative: grasslands are powerful carbon sinks, biodiversity hotspots, and livelihood lifelines for millions of pastoralists.

Concept Breakdown  

1. Colonial Legacy → Policy Misclassification

• Semi-arid grasslands and savannahs entered land records as “wastelands”.

• Influenced post-independence policy → creation of National Wastelands Development Board (1985).

• Result: Grasslands converted for:

  • tree plantations

  • industrial use

  • agriculture

  • afforestation schemes

Impact: systematic degradation of grassland ecosystems.

2. Ecological Role of Grasslands (vs. Forests)

 Below-Ground Productivity (Unique to Grasslands)

• Deep, fibrous roots →
  ✔ stabilise soil
  ✔ improve water infiltration
  ✔ reduce erosion
  ✔ enhance soil organic carbon (SOC)
  ✔ support rich microbial diversity

  Fire Resilience

• Unlike forests, grassland carbon remains largely unaffected by fire because it is stored underground.

3. Case Study 1: Malshiras Grassland Restoration, Maharashtra

• CAMPA funds used for native grass restoration (Dicanthium, Chrysopogon, Cenchrus).

• Study showed:

  • 21% SOC increase after 2 years

  • 50% SOC increase after 3 years

• Demonstrates how restoration > afforestation for semi-arid regions.

KPSC Angle: CAMPA + Ecosystem Restoration + Carbon Sequestration.

4. Case Study 2: Banni Grasslands, Gujarat

Once Asia’s largest tropical grassland → degraded by invasive Prosopis (mesquite) plantation.

Community-Led Restoration (Wada System)

• Prosopis removal

• Native grasses regenerated

• Managed by Maldhari pastoralists through rotational grazing

Key Findings:

• Banni stores 27 tonnes carbon (up to 30 cm soil depth)

• Average SOC: ~120 t/ha → among highest in global arid ecosystems

• Best SOC:
  Restored grassland > Wetlands > Dense woodland > Mixed woodland > Saline patches

KPSC Angle: invasive species, community-led conservation, sustainable pastoralism.

5. Why Grasslands Are India’s Climate Shields

• More stable SOC than forests

• Better resilience to rising temperatures

• Lower fire vulnerability

• Support millions in livestock-based economy

• Restore hydrological balance in drylands

Keywords to Use in Answers

• Below-ground biomass dominance

• Soil Organic Carbon (SOC)

• Ecosystem-based climate adaptation (EbA)

• Pastoralist-led governance

• Misclassification of ecosystems

• Invasive alien species (Prosopis juliflora)

• Dryland climate resilience

One-Line Takeaway for Aspirants

India’s climate solutions won’t come only from planting trees — they lie hidden in the soil beneath healthy, restored grasslands.

MAINS QUESTIONS

• “India’s drylands require restoration, not afforestation.” Explain with reference to grassland ecology and climate resilience.

• Discuss the role of community-led management in restoring degraded ecosystems with special reference to the Banni grasslands.
