Hi Shukraj,

I think the Internet has so much stuff on this subject, so I'm sure you have done a Google Search & had a look. Please keep notes on the sites that are interesting & then read them up in detail.

In very simple terms, it is the burden that one puts on the Earth's ecology through one's lifestyle. It could never be zero, but id we are conscious about its impact, we can make changes in our lifestyle to minimize the effect.

Sir, Shukra Raj Paudel

I would like to add that EFP is demand and supply count that nature could provide to human being. Also, agree with Sir, Emmanuel Vijayanand Murray that internet has lots of stuff and many research publications are there. Please follow the link for more information.

The ecological footprint is a concept introduced by Mathis Wackernagel in the 1990s and aimed at quantifying the amount of resources needed to maintain a certain lifestyle. Several ecol. footprint calculator exist on-line and these allow anybody to verify whether or not we live within the resource limits imposed by inhabiting only one planet Earth, or not.

Ecological footprint is a measure of human demand on the Earth's ecosystems. It is a standardized measure of demand for natural capital that may be contrasted with the planet's ecological capacity to regenerate. It represents the amount of biologically productive land and sea area necessary to supply the resources a human population consumes, and to mitigate associated waste. Using this assessment it is possible to estimate how much of the Earth it would take to support humanity if everybody followed a given lifestyle.

Please have a look at these links for more details.

Ecological foot print is an analysis that gauges our impact on the planet's biological systems, the ecological footprint measures human consumption of natural resources in comparison to Earth's ecological capacity to regenerate them. Individually, each of us has "a footprint," and, collectively, they aggregate across geographical zones and other means of classification. Calculation of the footprint takes into account just about everything we do; from the food we eat, to the house we live in, to the car we drive and the other consumption habits we practice each day. It's a very complex calculation that answers a straightforward question: how much of the Earth's resources do our lifestyles require?

The Ecological Footprint is a resource accounting tool used by governments, businesses, educational institutions and NGOs to answer to a specific resource question: How much of the biological capacity of the planet is required by a given human activity or population?

The Ecological Footprint measures the amount of biologically productive land and sea area an individual, a region, all of humanity, or a human activity that compete for biologically productive space. This includes producing renewable resources, accommodating urban infrastructure and roads, and breaking down or absorbing waste products, particularly carbon dioxide emissions from fossil fuel. The Footprint then can be compared to how much land and sea area is available.

Biologically productive land and sea includes cropland, forest and fishing grounds, and do not include deserts, glaciers and the open ocean.

Current Ecological Footprint Accounts use global hectares as a measurement unit, which makes data and results globally comparable. Calculation methods are standardized so results of various assessments can be compared.

The ecological footprint measures human demand on nature, i.e., the quantity of nature it takes to support people or an economy. It tracks this demand through an ecological accounting system. The accounts contrast the biologically productive area people use for their consumption to the biologically productive area available within a region or the world (biocapacity - the productive area that can regenerate what people demand from nature). In short, it is a measure of human impact on Earth's ecosystem and reveals the dependence of the human economy on natural capital.

The ecological footprint is defined as the biologically productive area needed to provide for everything people use: fruits and vegetables, fish, wood, fibers, absorption of carbon dioxide from fossil fuel use, and space for buildings and roads.
