HOME - Ecological Footprint - Ecological Sustainability
Global Footprint Network is an international think tank working to advance sustainability through use of the Ecological Footprint, a resource accounting tool that measures how much nature we have, and how much we use. This tool is unique in making overshoot measurable – through detailed resource accounts for nations, cities and individuals. By working with governments, investors and opinion leaders we demonstrate the advantages of making ecological limits central to decision-making. During our ten-year history, we’ve engaged with 57 national governments on six continents with one overarching goal: that all people live well, within the means of one planet.

Ecological footprint (Human) ecological footprint is a measurement of anthropogenic impact on earth. Two fields of science scope human impact on Earth; they are geospheric and biospheric sciences. Human activity is measured through ecological footprint research. Our activity is now the leading cause of climate change. [1] Our impact is now threatening total global collapse. [2] [3] Since the 1950s the human footprint has grown so massive that it has caused Earth to enter into an new geological epoch called The Anthropocene.[4] Biosphere Measurements[edit] Tandem silicon-perovskite solar cells could provide solar power on the cheap By combining silicon solar cells with their cheap and efficient perovskite-based counterparts, researchers at Stanford and MIT are creating a new type of "tandem cell" that could reach efficiencies up to 35 percent. Out of all the solar cell technologies discovered so far, perovskite certainly takes the cake as the fastest-growing and one of the most promising for the future. In just a few years of development, perovskite-based cells have gone from efficiencies in the low single digits to a respectable 20 percent. The more traditional silicon based single-junction cells are still in the lead on the efficiency front, but progress has slowed to a crawl as their output approaches the theoretical maximum.

Videos Hans Rosling explains a very common misunderstanding about the world: That saving the poor children leads to overpopulation. Not only is it not right, it’s the other way around! The world might not be as bad as you might believe! Don’t Panic – is a one-hour long documentary produced by Wingspan Productions and broadcasted on BBC on the 7th of November 2013. The visualizations are based on original graphics and stories by Gapminder and the underlaying data-sources are listed here. Berlin Farm Lab Some visual input from the first day of the gardening season. Thank you, Melina Daphne Papageorgiou for the beautiful photos! if you want to garden, come and find us every saturday at the Beilsteinerstrasse 51, in Berlin-Marzahn. more to come!

Zapatista Escuelita: Autonomous Government I Photo by The New Significance, January 2014 By The New Significance: In January 2014 The New Significance participated in the third Zapatista Escuelita, held in the mountains of southern Mexico, Chiapas. We went to learn about the – more than 20 year – Zapatista struggle for indigenous autonomy and self-governance. The Escuelita (little school) hosted more than 1,500 individuals and included visiting one of the five caracoles representing numerous Zapatista villages. Visiting a Zapatista village, living with Zapatista families, participating in individual work, collective work, and learning about Zapatista systems of education and healthcare.

Living Planet Report The Living Planet Report is the world's leading, science-based analysis on the health of our planet and the impact of human activity. Knowing we only have one planet, WWF believes that humanity can make better choices that translate into clear benefits for ecology, society and the economy today and in the long term. This latest edition of the Living Planet Report is not for the faint-hearted. One key point that jumps out is that the Living Planet Index (LPI), which measures more than 10,000 representative populations of mammals, birds, reptiles, amphibians and fish, has declined by 52 per cent since 1970.

The EcoTipping Points Project Long famous for its cathedral, university, and cuckoo clocks, Freiburg is now also famous as a “Green City.” It excels in the areas of transportation, energy, waste management, and land conservation, and has created a green economy that perpetuates even more environmental progress.

Where Do You Belong? 20 Videos Exploring Geography : KQED Education Homeland: Immigration in America/Nine Network By Sarah Bremer My students carry GPS-enabled devices (smart phones) in their back pockets and view paper maps as artifacts from a distant past. Regenerative Organic Agriculture and Climate Change We are at the most critical moment in the history of our species, as man-made changes to the climate threaten humanity’s security on Earth. But there is a technology for massive planetary geo-engineering that is tried and tested and available for widespread dissemination right now. It costs little and is adaptable to local contexts the world over. It can be rolled out tomorrow providing multiple benefits beyond climate stabilization. The solution is farming. Simply put, we could sequester more than 100% of current annual CO2 emissions with a switch to widely available and inexpensive organic management practices, which we term “regenerative organic agriculture.”
