How Can People Use the Ecological Footprint Tool to Manage Our Planet's Assets?
WHY DO Nosotros Need A FOOTPRINT?
What adept is a plane without cockpit dials? Sure, it flies. But how high, how fast, and in which direction? What is its exact position? In rough weather or at dark, flying without instruments becomes sketchy. Even in good weather. Particularly if basic instruments — like the fuel judge — are missing. Without knowing how much fuel is left in the tanks, whatsoever flying becomes unsafe.
Operating an economy is similar. Like a plane, an economic system is fueled. The deviation is that an economic system not only requires kerosene but also devours coal, nutrient, timber, water, and many other materials our planet provides. How many resources does it take for each breakfast, vacation, or new apartment each person may enjoy? How much nature does a city, a ability constitute, a nation, or the entire homo enterprise use? If nosotros are so utterly dependent on all these resources, how come our economies do not have fuel gauges?
In our daily lives, we pretty much know the dollar value of everything. Why? Because our financial budgets are limited. We desire to know what we tin afford. Like our own financial budget, nature's resource upkeep is limited too. And the female parent of all resources, the nearly limiting resource, is, as we will see, the biological avails — our planet's biocapacity. So how much nature can we afford? And if indeed nature'southward upkeep is limited, why don't nosotros measure it?
One possible reply is that we did non have a reasonable instrument for measuring our demand on nature. Also, for a long fourth dimension, no tool was needed, since nature appeared to be immense and endless. Information technology is different today. At present nature's limits accept become obvious, whether it is groundwater depletion, climate change, or decline of the oceans' fish stocks.
Good measurement instruments finally be: with the Ecological Footprint, we tin measure our use of nature. It offers a basic ecological accounting system. While for the economic system, coin is typically used as the accounting unit, the Footprint uses biologically productive surfaces of the Earth as its currency. These surfaces harbor the most meaning resource on our planet: the capacity of Earth to renew itself. On surface areas, photosynthesis transforms sunlight, water, nutrients into plant matter, over and over over again. Therefore, every need of the economy on nature's ability to produce and renew found matter can be expressed as the respective surface area needed to meet this demand. Yield figures tell united states how much cropland, a forest, or grazing country provides each twelvemonth. This is the demand side of the story.
We tin can too measure with ever greater precision what nature supplies, thanks to modern technology. Satellites deliver us upwards-to- engagement images of our planet. They show where forests, cities, streets, deserts, lakes, pastures, or grasslands are located. Those satellite pictures can be verified past straight measures in the field. On-the- ground measures track, for instance, how many potatoes or how much wheat is actually grown. At the country level, United Nations statistics provide detailed numbers for nearly of these resource flows: land areas, yields of the various state types, amounts produced and traded, population size, energy use, and and then on.
Financial accounts always look at two sides: income against expenditures, or assets confronting liabilities. Footprint accounting is tracking demand on nature against what nature renews. Information technology is a bones, straightforward, science-based description: How much nature is bachelor (income)? How much nature exercise people use (expenditure)? To manage the ecological capital of our planet only on gut instincts does not make much sense. No one would bring their money to a banking company that does no bookkeeping. A bank statement gives us an objective fiscal review — a condition report. This is exactly what's needed for the resource state of affairs of the planet at this time. That's the reason why the Footprint primarily aims at government and business decision-makers. Simply these accounts too need to be understood by the citizenry so they can hold their decision-makers accountable.
The Footprint reveals how much of our planet's productive area is used for each human activity. Circuitous processes can be summed up in one single number, similarly as money gets reported in elementary numbers like Return on Investment or Acquirement versus Costs. This boils circuitous issues down to their essence and makes them accessible. Information technology allows usa to negotiate. The Footprint, therefore, is not only a advice tool that is intuitively understood past a wide public. It likewise serves every bit a transparent tracking tool to measure the performance of policies and the implications of decisions in public and private domains.
The parallels betwixt economy and ecology goes beyond their names. In both domains, mismanagement is characterized by spending more than you earn. Physics and value creation accept to go hand in hand: how tin can the value of real manor expand continuously, even if the bodily real estate object does not modify? How can we continuously accumulate a huge amount of debt and promise that somehow quondam it can be paid off? How can nosotros continuously increase money supply without adding commensurate tangible value (even Google searches are "material," and and then are bitcoins, digital photographs, or iTunes).
How tin can we presume that expansion works forever? How tin nosotros expect an economy to forever deliver more than, without expanding the natural capital letter needed to fuel the economy accordingly? How come nosotros unremarkably forget that income generation depends on resource availability?
According to the latest Footprint calculations, humanity overused nature's biological budget (the biocapacity of the planet) by 75% in 2019. In other words, humanity uses nature currently 75% faster than it renews. This overuse is called ecological overshoot. Virtually estimates predict that the global population will rise from nigh 7.7 billion today to nine or 10 billion in 2050. And the residents of the BRICS countries (Brazil, Russia, India, Prc, S Africa) volition continue to work hard to raise their standards of living. And so will many others, in spite of potential economic turmoil. All these forces turn resource security into the central challenge of the 21st century.
