Question

Ecological Foot Print (EFP) does not measure-

• A. Amount of waste generated by human population
• B. Consumption of natural resources by human population
• C. Income generated by human population
• D. Demand of human from ecosystems

Hint:

Ecological Footprint vs. Economic Metrics:
- EFP measures biophysical demand in global hectares (gha).
- It tracks resource consumption and carbon waste absorption.
- It does NOT measure financial variables like income, capital, or monetary wealth.

Answer 1

The Correct Option is C

Concept:
The Ecological Footprint (EFP) is a resource accounting tool formulated in the 1990s by William Rees and Mathis Wackernagel.
It measures how much biologically productive land and water area an individual, population, or human activity requires to produce the resources it consumes and absorb the wastes it generates.

Step 1: Biophysical Components Measured by EFP:
The ecological footprint quantifies the human demand placed on the planet's biocapacity, measured in standardized units called global hectares (gha):
1. Demand on Ecosystems (D): Tracks demand across distinct bioproductive surfaces (cropland, grazing land, fishing grounds, and forest land).
2. Resource Consumption (B): Calculates food, timber, pulp, textile fibers, and water extracted to sustain human populations.
3. Waste Assimilation (A): Quantifies the forest area required to absorb emissions, particularly fossil-fuel carbon dioxide emissions (carbon footprint).

Step 2: Identification of Non-Biophysical Parameters:
Income generated by human population (C): Monetary income, gross revenue, and GDP are financial metrics calculated in fiat currencies.
The Ecological Footprint is purely a biophysical accounting metric that does not evaluate personal income, wage levels, or financial earnings.
Economic wealth can correlate with footprint size, but income itself is not an ecological variable measured by the tool.
Final Answer:
The Ecological Footprint does not measure the income generated by human population, corresponding to option (C).
