Annual Deforestation Rate vs Total Forest Area
Formula
## How to Calculate Deforestation Rate Deforestation rate tracks the annual loss of forest cover. ### Formula **Rate (%) = Annual Loss / Total Forest * 100** **CO2 Released = Lost Area * CO2 per Hectare** ### Carbon Storage - Tropical forest: 150-250 metric tons CO2/ha - Temperate forest: 100-200 metric tons CO2/ha - Boreal forest: 50-150 metric tons CO2/ha Deforestation accounts for about 10% of global CO2 emissions.
Exemplo Resolvido
A 10,000 ha forest losing 200 ha/year with 150 metric tons CO2/ha stored.
- 01Deforestation rate: 200 / 10,000 * 100 = 2%
- 02CO2 released: 200 * 150 = 30,000 metric tons/year
- 03Years to depletion: 10,000 / 200 = 50 years
- 045-year loss: 200 * 5 = 1,000 hectares
Perguntas Frequentes
How much forest is lost each year?
About 10 million hectares (25 million acres) of forest are lost annually, an area roughly the size of Portugal. The rate has slowed from 16 million ha/year in the 1990s.
What drives deforestation?
Agriculture (especially cattle and soy) causes 80% of deforestation. Other drivers include logging, mining, infrastructure, and urbanization. The Amazon, Congo Basin, and Southeast Asia are most affected.
Can reforestation reverse the damage?
Reforestation helps but takes decades to restore carbon stocks and biodiversity. Old-growth forests store far more carbon and support more species than newly planted ones.
