Sustaining Seven Billion People

Sustaining Seven Billion People | green infographics | Scoop.it

"With seven billion people now living on Earth, the ever growing demand is putting unprecedented pressure on global resources—especially forests, water, and food. How can Earth’s resources be managed best to support so many people? One key is tracking the sum of what is available, and perhaps nothing is better suited to that task than satellites."

Seth Dixon's curator insight, June 24, 6:53 AM

Agricultural production is one of the ways in which people modify the environment more than any other.  Global population is expected to top out at around 9 billion around 2050, so will we be able to sustainably feed all of the entire human population?  Satellite imagery can help answer these questions.

Russell Roberts's curator insight, July 5, 9:53 PM

Thanks to environmental reporter Wes Thomas and professor Seth Dixon for this incisive analysis of how to provide sustenance to a world population nearing the 7 billion mark.  Dixon says the key is tracking the "sum of what is available...and perhaps nothing is better suited to the task than satellites."  Ever since the launch of "Landsat" and resource imaging satellites, scientists have been collecting data on global resources such as water, land use, forests, and crop production.  Dixon and Thomas say it's time the data were  put into a plan to fight hunger and habitat destruction around the world.  Such a plan may work if we as humans can keep from killing ourselves over religion, politics, and territory.  A tall order , indeed.  Aloha de Russ.

Daniel LaLiberte's curator insight, July 6, 9:09 AM

Such studies of the agriculture around the world are essential. The way we are doing agriculture to support seven billion people now, peaking at 9-10 billion in another 60 years, it is clear that we are putting severe strains on the environment.  But we have grown lazy, and we are doing it all wrong.

 

We CAN drastically reduce the amount of meat we consume, and thus quickly reduce the amount of arable land we need.  We CAN grow plants in ways that actually sequester more carbon and improve the soil it over time rather than erode and degrade.  And we CAN in fact grow all the food we need in the space we live in, thus enabling us to recycle all the water used as well, which is mostly just lost in evaporation.

Factory Food From Above: Satellite Images of Industrial Farms

Factory Food From Above: Satellite Images of Industrial Farms | green infographics | Scoop.it

Seen from a satellite, an industrial feedlot has a sort of abstract beauty. The washes of colors, the juxtaposition of organic and rigid geometries, initially obscure the subject. Then comes the realization:That’s where our food comes from.

Such is the power of “Feedlots,” a new series of images crafted by British artist Mishka Henner from publicly available satellite photographs. Henner does work with the photos, enhancing the colors — the waste lagoons above, for example, are flat green rather than bright — but the physical details are unaltered.

Henner, who noticed the feedlots while scanning for pictures of oil fields in Texas, didn’t at first realize what he was looking at. Factory farms exist in the United Kingdom, but not at landscape scales.

Even for Americans, though, these sights are unusual. Industrial farming, especially of animals, tends to be hidden from public view — and under so-called ag-gag laws, that secrecy could become law.

A View Of Antarctica From Outer Space

A View Of Antarctica From Outer Space | green infographics | Scoop.it

This image photographed almost ten years ago on September 21, 2005, shows a gorgeous, pristine view of Antarctica. It was taken with the AMSR-E instrument onboard NASA’s Aqua satellite. 
Upon zooming in, one can see magnificent details of the awe-inspiring sea ice, and how much space it occupies in relation to the rest of the planet.
