According to the 'India State of Forest Report (ISFR) 2019', India's total forest and tree cover stands at 80.73 million hectares, representing 24.56% of the country's total geographical area. These ecosystems provide vital services, and any significant alteration in forest cover directly impacts global climate change.
Status of Forest Resources in India
Growth Trends: Compared to ISFR 2017, the 2019 assessment recorded a 0.65% increase in combined forest and tree cover at the national level.
Leading States: The top five states/UTs showing the highest increase in forest cover are Karnataka, followed by Andhra Pradesh, Kerala, Jammu & Kashmir, and Himachal Pradesh.
Hilly and Tribal Areas: Forest cover in hill districts is 40.30%, while tribal districts exhibit 37.54% forest cover.
North-Eastern Region: The Northeast maintains a high forest cover of 65.05%, but the region saw a net decrease of 765 sq km (0.45%), with all states except Assam and Tripura showing a decline.
Mangroves and Wetlands: Mangrove cover increased by 1.10%. Wetlands cover 3.83% of the country's recorded forest area (RFA), with Gujarat having the largest wetland area, followed by West Bengal.
Resource Dependency: Fuelwood dependency is highest in Maharashtra, while Madhya Pradesh shows the highest dependence on forests for fodder, small timber, and bamboo. Around 7% of the annual forest yield is harvested as small timber by forest-fringe communities.
Influence of Forests on Climatic Conditions
Temperature Regulation: Forest canopy reduces mean annual temperatures, lowering daily maximums and raising daily minimums.
Local Precipitation: Forests have a negligible effect on rainfall at low elevations, but significantly enhance precipitation in mountainous and high-altitude regions.
Atmospheric Humidity: Forest cover increases relative humidity and reduces evaporation rates from the ground compared to open areas.
Transpiration: Forests absorb soil moisture and release it back into the atmosphere through transpiration, driving the local water cycle.
Soil Health and Water Retention: Forests enrich soil fertility, reduce surface runoff, and enhance groundwater percolation, which feeds natural springs in hilly terrains.
Conclusion
Forests are a cornerstone of climate change mitigation. Globally, they sequester about 2.6 billion tonnes of carbon dioxide annually—equivalent to one-third of the CO2 emitted from fossil fuels. Protecting and expanding forest cover is therefore critical to achieving climate resilience.
