Deforestation

noun (uncountable)
/diːˌfɒrɪˈsteɪʃən/
The large-scale removal or clearance of forests, converting forested land to non-forest uses such as agriculture, settlement, or infrastructure, leading to permanent loss of forest cover. In the disaster-management context, deforestation amplifies flood risk (by reducing interception and infiltration), landslide risk (by removing root systems that bind slopes), and drought risk (by reducing evapotranspiration and local rainfall). India's Forest Survey of India (FSI) State of Forest Report 2021 assessed total forest and tree cover at 80.9 million hectares (24.62% of geographic area), though the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) has flagged conversion of dense forest to open or scrub as a continuing net loss.

✍️ Usage in a UPSC answer

The Environment Impact Assessment Notification of 2020 drew sharp criticism from ecologists and disaster managers who argued that relaxing prior scrutiny for linear infrastructure projects in ecologically sensitive areas would accelerate deforestation in the Western Ghats and Himalayan foothills, increasing landslide and flood risks in downstream districts.

🔡 Root

Latin de- = removal, reversal + Old French forest (from Medieval Latin forestis) + -ation = process suffix

📜 Etymology

Formed from the prefix de- (indicating removal or reversal, from Latin de-) plus 'forestation' (the action of planting a forest). 'Forest' itself entered Middle English from Old French forest, derived from Medieval Latin forestis silva (the woodland outside the enclosed park), from Latin foris (outside). The reverse process, deforestation, began to be documented systematically in colonial-era land surveys of the 19th century, and the term gained widespread policy usage following the founding of the FAO and the first global forest assessments in the mid-20th century.

🧠 Memory Hook

DE (remove) + FOREST + ATION: to DE-FOREST is to remove the forest. The prefix de- always signals reversal or removal in English — de-frost, de-rail, de-mobilise. Deforestation is the removal of the forest itself, the undoing of nature's green cover. Picture the prefix de- as an eraser wiping trees off a hillside.
