🏜️Land Degradation & Wastelands in India

Desertification trends, degradation processes, wasteland classification (NWDB & Atlas 2019), state-wise statistics, and per capita agricultural land

Soil erosion strips topsoil, salinity poisons root zones, and waterlogging suffocates crops — all forms of land degradation that convert productive farmland into wastelands. India lost an additional 1.45 Mha to desertification between 2011 and 2019, while nearly 56 Mha of its land sits classified as wasteland. Understanding the scale, processes, and geography of degradation is essential for soil conservation planning.


Land Degradation & Desertification

Overview

  • Total area under desertification: 97.85 Mha (29.77% of Total Geographical Area) during 2018–19
  • This represents an increase of 1.45 Mha from 2011–13
  • Most significant process: Water Erosion (11.01%), followed by Vegetation Degradation (9.15%) and Wind Erosion (5.46%)

Dominant Degradation Processes by Region

RegionDominant Process
Arid regionsWind Erosion
Semi-arid & Dry Sub-humid regionsWater Erosion and Vegetation Degradation

Land Degradation by Process

ProcessArea (Mha)
Water Erosion36.20
Vegetation Degradation30.07
Wind Erosion17.94
Salinity3.64
Water Logging0.80
Total97.85

Water erosion is the single largest contributor to land degradation in India, affecting 36.20 Mha.


Salinity Affected Areas by State

StateArea (Lakh ha)
Gujarat25.99
Rajasthan3.66
Uttar Pradesh2.83
Andhra Pradesh1.19
Karnataka0.89

Gujarat has the highest salt-affected area due to the Rann of Kutch and coastal salinity ingress.


Per Capita Agricultural Land

RegionPer Capita Agri Land
India0.12 ha
World0.29 ha

India’s per capita agricultural land is less than half the world average, highlighting intense pressure on land resources.

Note: Above figures are from the Wasteland Atlas 2019 and refer to total agricultural land (arable + permanent crops + pastures). Using arable land only, World Bank 2023 data shows India at 0.107 ha/person and world average at 0.172 ha/person.


Wastelands in India

Classification

The National Wastelands Development Board (NWDB) classifies wastelands into two broad categories (14-type scheme). The Wasteland Atlas 2019 (5th edition, NRSC/DoLR) uses a more detailed 23-category classification.

CategoryNumber of Types
Cultivable Wastelands11 types
Uncultivable Wastelands3 types

Cultivable Wastelands (11 Types)

  1. Gullied and/or ravinous land
  2. Undulating upland without scrub/shrubs
  3. Surface waterlogged land
  4. Salt-affected land
  5. Shifting cultivation areas
  6. Degraded forest land (open & dense)
  7. Degraded pastures/grazing land
  8. Degraded land under forest plantations
  9. Strip lands
  10. Sand dunes (coastal & desertic)
  11. Mining/industrial wastelands

Uncultivable Wastelands (3 Types)

  1. Barren rocky/stony areas
  2. Steep slopy areas
  3. Snow covered/glacier lands

Overall Figures

ParameterValue
Total wastelands (2015–16)55.76 Mha (16.96% of geographical area)
Total wastelands (2008–09)56.60 Mha
Reduction (2008–09 to 2015–16)8,404 sq km
Highest wasteland (state/UT)Jammu & Kashmir (undivided, pre-2019) — 1,75,697 sq km
Lowest wasteland (state/UT)Delhi — 81.27 sq km

Change Across States

  • Wastelands decreased in 18 states and increased in 11 states

States with Maximum Wasteland Reduction (Positive Change)

StateReduction
Rajasthan0.48 Mha
Bihar0.11 Mha
Uttar Pradesh0.10 Mha
Andhra Pradesh0.08 Mha

States with Wasteland Increase (Negative Change)

StateIncrease (sq km)
Odisha465.82
Assam406.69
Telangana377.79
Chhattisgarh373.54

Rajasthan showed the highest positive change (reduction in wastelands) of 0.48 Mha, largely due to reclamation of sand dune areas and afforestation efforts. Conversely, Odisha saw the highest increase in wastelands.

Update (Nov 2024): SAC/ISRO published a supplementary Land Degradation Vulnerability Assessment atlas — it maps vulnerability to future degradation (not current extent). No new edition of the main Desertification Atlas or Wasteland Atlas has been released as of April 2026.
