Feeding the World Sustainably: Agroecology vs. Industrial Agriculture

Feeding the World Sustainably: Agroecology vs. Industrial Agriculture | omnia mea mecum fero | Scoop.it
There are currently 1 billion people in the world today who are hungry. There's also another billion people who over eat unhealthy foods.

 Food production around the world today is mostly done through industrial agriculture, and by judging current issues with obesity, worldwide food shortages, and the destruction of soil, it may not be the best process. We need to be able to feed our world without destroying it, and finding a more sustainable approach to accomplishing that is becoming more important.

The current system contributes to 1/3 of global emissions, is a polluter of our world’s water resources, and is a contributor to health problems. Industrial agriculture relies on mass produced, mechanized labor-saving policies that have pushed people out of rural areas and into cities, consolidating land and resources into fewer hands.

Agroecology looks to reduces agriculture’s impact on climate by working within natural systems. This is especially beneficial in rural areas, because the local community a major part of the growing process. The approach can conserve and protect soil and water — through terracing, contour farming, intercropping, and agroforestry — especially beneficial in areas where farmers lack modern irrigation infrastructure, or have farms situated on hillsides and other difficult farming sites...

Daniel LaLiberte's curator insight, October 1, 2013 9:53 PM

Clearly industrial agriculture is not sustainable, and must be replaced entirely with systems that reverse the current damage and restore the balance that used to exist before we messed things up.  We can use plants and animals not only to feed ourselves, but to *improve* the environment for all life on the planet.

The *Official AndreasCY*: Touch screen technology : How it works

The *Official AndreasCY*: Touch screen technology : How it works | omnia mea mecum fero | Scoop.it

The three most common touch screen technologies include resistive, capacitive and SAW (surface acoustic wave). Each technology offers its own unique advantages and disadvantages as described below. Resistive and capacitive touch screen technologies are the most popular for industrial applications. They are both very reliable.
If the application requires that operators can wear gloves when using the touch screen, then resistive is the recommended technology as capacitive doesn't support gloves. If operation with gloves is not required, then capacitive technology is the preferred choice due to better optical characteristics.

Resistive :

A resistive touch screen typically uses a display overlay consisting of layers, each with a conductive coating on the inner surface. The conductive inner layers are separated by special separator dots, evenly distributed across the active area. Pressure causes internal electrical contact at the point of touch, supplying the electronic interface (touch screen controller) with vertical and horizontal analog voltages for digitization. For CRT applications, resistive touch screens are generally spherical (curved) to match the CRT and minimize parallax. The nature of the material used for curved (spherical) applications limits light throughput such that two options are offered: Polished (clear) or antiglare.
The polished choice offers clarity but includes some glare. The antiglare choice will minimize glare, but will also slightly diffuse the light throughput (image). Either choice will demonstrate either more glare (polished) or more light diffusion (antiglare) than associated with typical non-touch screen displays. Despite the tradeoffs, the resistive touch screen technology remains a popular choice, often because it can be operated while wearing gloves (unlike capacitive technology). Note that resistive touch screen materials used for flat panel touch screens are different and demonstrate much better optical clarity (even with antiglare). The resistive technology is far more common for flat panel applications.
A capacitive touch screen includes an overlay made of glass with a coating of capacitive (charge storing) material deposited electrically over its surface. Oscillator circuits located at corners of the glass overlay will each measure the capacitance of a person touching the overlay. Each oscillator will vary in frequency according to where a person touches the overlay. A touch screen controller measures the frequency changes to determine the X and Y coordinates of the touch. Because the capacitive coating is even harder than the glass it is applied to, it is very resistant to scratches from (SIC) sharp objects. It can even resist damage from sparks. A capacitive touch screen cannot be activated while wearing most types of gloves (non-conductive).

Capacitive :

A SAW touch screen uses a solid glass display overlay for the touch sensor. Two surface acoustic (sound) waves, inaudible to the human ear, are transmitted across the surface of the glass sensor, one for vertical detection and one for horizontal detection. Each wave is spread across the screen by bouncing off reflector arrays along the edges of the overlay. Two receivers detect the waves, one for each axis. Since the velocity of the acoustic wave through glass is known and the size of the overlay is fixed, the arrival time of the waves at the respective receivers is known. When the user touches the glass surface, the water content of the user's finger absorbs some of the energy of the acoustic wave, weakening it.

Saw :

The controller circuitry measures the time at which the received amplitude dips to determine the X and Y coordinates of the touch location. In addition to the X and Y coordinates, SAW technology can also provide Z axis (depth) information. The harder the user presses against the screen, the more energy the finger will absorb, and the greater will be the dip in signal strength. The signal strength is then measured by the controller to provide the Z axis information. Today, few software applications are designed to make use of this feature.
Most manufacturers offer two controller configurations--ISA Bus and Serial-RS232. ISA bus controllers are contained on a standard printed circuit plug-in board and can only be used on ISA or EISA PCs. Depending on the manufacturer they may be interrupt driven, polled or be configured as another serial port. Serial controllers are contained on a small printed circuit board and are usually mounted in the video monitor cabinet. They are then cabled to a standard RS232 serial port on the host computer.
Most touch screen manufacturers offer some level of software support which include mouse emulators, software drivers, screen generators and development tools for Windows, OS/2, Macintosh and DOS. Most of the supervisory control and data acquisition (SCADA) software packages now available contain support for one or more touch technologies.

Top 100 Documentaries Inspiring the Shift to a Sustainable Paradigm

Top 100 Documentaries Inspiring the Shift to a Sustainable Paradigm | omnia mea mecum fero | Scoop.it
Film offers us a powerful tool to shift awareness and inspire action. It offers a method to break our dependence on the mainstream media and become the media ourselves. We don't need to wait for anyone or anything.

 

Just imagine what could become possible if an entire city had seen just one of the documentaries below. Just imagine what would be possible if everyone in the country was aware of how unhealthy the mainstream media was for our future and started turning to independent sources in droves.

 

Creating a better world really does start with an informed citizenry, and there's lots of subject matter to cover. Our country has to come to terms with the true history of Western civilization. It has to learn about basic ecology. It needs to understand some basic truths about peak oil and the monetary system, the truth about capitalism and governments.

 

Our society needs a new story to belong to. The old story of empire and dominion over the earth has to be looked at in the full light of day - all of our ambient cultural stories and values that we take for granted and which remain invisible must become visible.

But most of all, we need to see the promise of the alternatives - we need to be able to imagine new exciting ways that people could live, better than anything that the old paradigm could ever dream of providing.

 

And all of this knowledge and introspection, dreaming, questioning, and discovery is essential for a cultural transformation that addresses root causes. This knowledge is vitally necessary. Taken together, this knowledge, which is documented throughout the 100 documentaries we've selected below, will lay the foundation on which the next paradigm will be built, post empire.

 

So take this library of films and use it. Host film screenings, share these films with friends, buy and give copies to your elected officials and school faculty. Get this information out in to your community and you will be laying the foundation for a local movement for mass societal, environmental and economic change.

More than tools of discovery, though, images can help scientists communicate the reality of what they study to each other and the public. One poignant image can change not just the course of science, but also ordinary people's perception of their place in the cosmos. Here are ten powerful images that did just that.

Will we ever reveal all the secrets of life from DNA? It's very, very hard!

Will we ever reveal all the secrets of life from DNA? It's very, very hard! | omnia mea mecum fero | Scoop.it

We may have sequenced the human and other species’ genomes, but we are still nowhere near predicting how this creates a living, breathing organism. Here’s why:

 

In 2001, the Human Genome Project gave us an almost complete draft of the 3 billion letters in our DNA. We joined an elite club of species that have had their genome sequenced, one that is growing with every passing month. As our technologies and understanding advance, will we eventually be able to look at a pile of raw DNA sequence and glean all the workings of the organism it belongs to? Just as physicists can use the laws of mechanics to predict the motion of an object, can biologists use fundamental ideas in genetics and molecular biology to predict the traits and flaws of a body based solely on its genes? Could we pop a genome into a black box, and print out the image of a human? Or a fly? Or a mouse? Not easily. In complex organisms, some traits can be traced back to specific genes. If, for instance, you’re looking at a specific variant of the MC1R gene, chances are you’ve got a mammal in front of you, and it has red hair. Indeed, people have predicted that some Neanderthals were red-heads for precisely this reason. But beyond that, predicting if something is a mouse or a whale or a armadillo, we still can't do it.

 

Bernhard Palsson from the University of California, San Diego agrees. “Sequencing a woolly mammoth will not predict its properties,” he says. “But you might be able to do a lot better with bacteria.” Their simpler and smaller genomes should in theory make it easier to predict the basic features of their metabolism, or whether they grow using oxygen or not. But even though we can sequence a bacterial genome in under a day, and for just $80, we would still struggle to determine important traits, like how good a disease-causing microbe is at infecting its host.

 

Finding all the genes even in a small genome is hard. Earlier this year, scientists discovered a new gene in a flu virus whose genome consists of just 14,000 letters (small enough to fit into 100 tweets), and had been sequenced again and again. So it should be unsurprising that our own genome, with 3 billion letters, is full of errors and gaps, despite ostensibly being “complete”. In May, another group showed that the reference human genome is missing a gene that may have shaped the evolution of our large brains. “There’s no genome that is completely understood even in terms of the genes within it,” says Markus Covert from Stanford University. “Typically, no function is known for a fourth to a fifth of the genes, even in smaller genomes.”

The materials are plentiful and the process of twisting, shaping and lacquering makes for a frame that's strong and durable, inventor Izhar Gafni says. Mass production is supposed to start in the next few months.

 

The inventor, Izhar Gafni, believes the bike could be a boon to the world's most traffic-congested cities and help people in remote parts of the Third World get from place to place. He's reached a deal to start mass production in a few months, Gafni tells Reuters.

 

How did he do it? As Reuters says, "once the shape has been formed and cut, the cardboard is treated with a secret concoction made of organic materials to give it its waterproof and fireproof qualities. In the final stage, it is coated with lacquer paint for appearance."
