The ecological footprint is an aggregate indicator defined as «the area of ecologically productive territory (crops, pastures, forests or aquatic ecosystems) necessary to produce the resources used and to assimilate the waste produced by a given population with a specific way of life in a way indefinite ». Its fundamental objective is to evaluate the impact on the planet of a certain way or way of life and, consequently, its degree of sustainability.
The advantage of the ecological footprint in understanding human appropriation is in harnessing the ability to make comparisons. It is possible to compare from the emissions of transporting a particular good with the energy required for the product on the same scale (hectares). If you want to discover how you can know the impact you have on the planet, calculate your ecological footprint with the advice and details that we give you in Green Ecologist and, in addition, know details about how to reduce it.
The ecological footprint is the indicator that serves to measure the environmental impact that the habits of each person produce in the environment and their degree of sustainability.
Therefore, sustainability indicators are tools that are used to report on the situation and evolution of the environment, see how human actions impact it and seek solutions.
Different types of indicators are used to measure the degree of sustainability. Each of them affects a specific aspect of the environment, such as its state, or evolution in light of the measures adopted.
In recent years, our country has experienced an appreciable migration from rural areas to urban centers. This means that by abandoning crops and agricultural production, the population is more dependent on foreign products.
Large areas of crops are required to meet the basic needs of the population. This causes a degeneration of the soil, the gradual disappearance of biodiversity and the ecosystem and dependence on mechanical locomotion systems as distances become greater. This need, in turn, causes us to be increasingly dependent on petroleum derivatives and fossil fuels.
All this leaves behind what is known as an ecological footprint that is increasing more and more and is more evident. Any action, no matter how minimal, impacts the ecosystem in one way or another.
¿How the ecological footprint is calculated? Carrying out the calculations of the environmental impact that each of us causes individually is not an easy task. However, there are approximations and methods to carry out the calculations in a more or less approximate way.
The ecological footprint would be the result of the sum of these variables and is expressed in hectares per inhabitant and year. Two main steps are followed to carry out the calculation.
Apparent consumption is measured through the following equation: Consumption = P (Production) - E (Export) + I (Import)
Apparent consumption is transformed into productive area based on the following equation:Ecological footprint = C (Consumption) / P (Productivity)
In our country it is estimated that each of us need an average of 6.5 Ha of space per capita to meet our consumption and waste disposal needs. The current population in Spain is 46,800,000 people, so we would need one land area of almost 300,000 hectares. However, the reality is that the total area of our territory barely exceeds 50,000,000 hectares, five times less than what we would need to satisfactorily cover our needs.
This gives us the dubious honor of being among the top positions in Europe and the world in leaving the largest ecological footprint. Therefore, it would not hurt to seriously rethink the impact we cause on the environment and vary our consumption habits.
We must be aware that it is not possible to continue with the current pace. Government action around the world remains tepid and does not firmly tackle the problem with protective measures or sanctions for those who violate the rules.
