Enter the amount of deforestation (acres) and the total time (years) into the Calculator. The calculator will evaluate the Deforestation Rate. 

Deforestation Rate Formula



  • DEFR is the Deforestation Rate (acres/year)
  • DEF is the amount of deforestation (acres)
  • T is the total time (years)

To calculate the Deforestation Rate, divide the amount of deforestation by the total time period.

How to Calculate Deforestation Rate?

The following steps outline how to calculate the Deforestation Rate.

  1. First, determine the amount of deforestation (acres). 
  2. Next, determine the total time (years). 
  3. Next, gather the formula from above = DEFR = DEF / T.
  4. Finally, calculate the Deforestation Rate.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

amount of deforestation (acres) = 50000

total time (years) = 2


What is deforestation and why is it a concern?

Deforestation refers to the removal of a forest or stand of trees where the land is thereafter converted to a non-forest use. It is a concern because it leads to biodiversity loss, contributes to global warming, disrupts water cycles, and can lead to soil erosion.

How can the Deforestation Rate help in environmental conservation?

Understanding the Deforestation Rate can help in environmental conservation by providing a quantitative measure of how quickly forests are being removed. This information can be used to develop strategies to reduce deforestation, promote reforestation, and manage forests sustainably.

Are there any global initiatives to reduce deforestation?

Yes, there are several global initiatives aimed at reducing deforestation, including the United Nations’ REDD+ program (Reducing Emissions from Deforestation and Forest Degradation), the Amazon Fund, and various conservation and sustainable management practices adopted by countries and non-governmental organizations.

How can individuals contribute to reducing deforestation?

Individuals can contribute to reducing deforestation by supporting and purchasing products from companies that have sustainable forest management practices, participating in tree planting activities, reducing paper consumption, and spreading awareness about the importance of forests.
