Cutting edge farming in a Coronado casita

TN

To get SUSTAINABLY spaced out, know about this technology

article and photos by Eric Jackson

What to do when our planet has a much larger population that’s jammed into mega-cities and needs to be fed? Especially if, due to climate change, mobile evolving blights and rising seas, a lot of once-arable land is no longer available for food production?

Or what do to if you have a hyper-advanced case of a certain sort of gringo culture and what used to be white flight to the suburbs leads you beyond gated expat enclaves to a colony on Mars or the Moon?

For that matter, in a shorter term, what if you are a Panamanian development planner and find the country with all of these money laundering towers, hardly anyone willing to stash and wash their ill-gotten funds here anymore and few of the theoretical foreign millionaires willing to to buy one of the many vacant condos?

You might try to convert the empty condo towers, or certain floors or units in them, into farms. Dr. Gary Stutte, who was a lead research for NASA in developing zero gravity farming techniques on the International Space Station, has in recent years turned his gaze downward to apply what was learned to Planet Earth. He foresees some apocalyptic changes in population and climate that might make it not just convenient, but necessary. In November he will be in Panama as the keynote speaker for a gathering of the International Congress on Controlled Environment Agriculture. See http://icceapanama.org/en/about-2/

Don’t go to the gathering decked out as a Trekkie. It will be a serious gathering, with business, government and academic sponsors from several nations and small-time devotees like Tom Norcross, who invested about $30,000 to turn the casita next to his house into a working leaf lettuce farm. At the conference they will discuss such mundane matters as:

  • Understanding Nutrients used in Hydroponics
  • Understanding Technology Used in Producing Greenhouse and
  • Vertically Farmed Produce
  • Learning the latest research available on controlled environment crops
  • How LED Grow Lights impact photosynthesis and plant growth
  • Learning new production techniques
  • Managing Business
  • Automation and Robotics
  • Blockchain

It’s a part-time gig for Norcross at the moment. If it’s to grow into something big, more likely he will be franchising small-scale systems like the one he runs now, or consulting with others, perhaps those involved in production on grand scales. For now, his main expense is the electric bill but he expects that in the large operations to come in Latin America and the world the main costs will be for labor.

Some of you old burnouts may remember the grow light and marijuana plants in the closet. The heat and electric bills were what would clue the narcs in about what you were doing if you got to scales brazen enough. That was before LED grow lights made both of those factors more manageable. But still, mold and pests could and often did take their tolls.

Norcross runs as totally controlled an environment as he can – non-toxic, and aseptic as possible. You enter the casita through a door protected by a blower to keep insects or mold spored from coming in with you. You are then in a little vestibule before another door, with another layer of that defense. The hydroponic grow room is kept sealed off with hand-washing and a hair net before entering it. The water, nutrient solution and computerized monitors of what’s going on in the grow room are in a separate room. Norcross carries a little cellular device that lets him keep tabs wherever he goes, making sure that the temperature is appropriately cool, the carbon dioxide level is elevated just a bit from what it is outdoors, the constantly spraying and recycling solution doesn’t get too acidic or alkaline and so on.

The romaine and baby greens that are the end product? They are hydroponic, grown in a water and fertilizer solution, so not by the standard definitions “organically grown.” But they are the good stuff, unlike most Panamanian produce not sprayed with herbicides, anti-fungal chemicals or insecticides. You don’t need to rinse this stuff off before eating it and Norcross recommends that you don’t.

Editorials: Panama’s maritime neutrality; and Thugs make things worse

0
ship from Biomuseo
Is Panamanian independence getting to be as antiquated as this ship?

A neutral maritime nation? Or whose vassal?

One of the last things that the Varela administration did was cancel the Panamanian registry of a tanker ship that the United States condemned as “terrorist” because it allegedly was used to transport Iranian oil to Syria. This, it was said, in furtherance of the US embargo against Iran and international anti-terrorist agreements. The vessel was later seized by the British as it attempted to pass through the Straits of Gibraltar.

This de-flagging at US insistence was preceded by the Varela policy of banning the Panamanian registry of ships that rescue migrants on the Mediterranean Sea, this at the request of the right-wing Italian government.

Now we have a new administration and a new head of the Maritime Authority, who will have cabinet rank in the Cortizo administration. It is announced that Panama will make sure that in the maritime ambit we follow all international agreements.

Which ones, and under whose interpretation?

One of the most important sets of international agreements that Panama has provides that the canal is a neutral waterway which ships of all nations may use. Is that now called off whenever Uncle Sam calls some other country “terrorist?”

And what about another great maritime dispute of our times, China’s claims of the South China Sea as its territorial waters, against the claims of several other nations, and its aggravation of that dispute by creating landfill islands on places that would be underwater at high tide, militarizing those and claiming territorial seas and exclusive economic zones around those. Are we to condone those practices, which arguably violate the applicable international agreements about the law of the sea, because China is a great power and important economic partner?

Now it will be up to Nito Cortizo. Is Panama aligned with a foreign master or independent? If Panama is aligned, with whom? You would expect that no sensible leader of little Panama would go hurling bombastic defiance at either the United States or China, that diplomacy will have to be more subtle. But there are still some decisions to make about what Panama is and intends to be, and however these are made there will be powerful people and nations who don’t like them.

 

 

He / she / it / they broke the lock on the back gate and reached in through the work station window.

Maleante weekend

July 4 through 7 was not a long weekend for Panamanians like in the USA. But here the thugs made it seem that way, with several days of homicides and assaults more befitting of a long weekend in the most heavily armed and crime-afflicted areas of the United States.

Was THAT all over? Late Monday morning your hard-working editor began this editorial page, then, already on short July rations – this is the month when the biggest bills come in — went into Anton for basic cat food, rice and coffee staples.

Returning, it was discovered that some local hoodlum – let’s not guess who – broke the lock on one of the back gates, couldn’t or didn’t break any other locks, reached in through the back window to the computer station where The Panama News is produced, and stole. He – pretty sure it was a he, but perhaps not – stole the wireless modem and stick. Stole the mouse. Stole the cable used for the modem. Stole the editor’s cell phone and charger, which wasn’t working anyway due to an apparent dead battery. Stole an old iPad which only works for a few things, but could not reach the charger cable for this. The laptop itself was kept out of the reach of burglars, as it habitually is.

About $100 would replace those stolen items used to produce The Panama News, not counting the cell phone and chip, the editor’s time or travel expenses to and from places where replacements might be found.

This is written offline, and posted and uploaded at a place with free WiFi. Production of The Panama News is disrupted for at least a few days. How many or few days depends on the generosity of readers. We were already in a hole for our annual web hosting and anti-hacking program rentals, and now this. Sorry about that.

To lend a hand via PayPal, which generally takes a few days, click on https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=N9GEGY9C3VSH8

To donate to The Panama News if PayPal does not work you can send money by wire, in the full name of the editor, “Eric Lea Jackson Malo,” who lives near Antón and Penonomé, via Western Union, MoneyGram, Super 99, Correos, etc. We need to know if you sent money and the routing number. Let us know at fund4thepanamanews@gmail.com.

The complications with this are that there is no phone connection and Internet connections are only brief and sporadic, when the editor is at a place with free WiFi. Ah, well. Many a cause has rebound from far worse a setback.

I do not wish women to have power over men; but over themselves.

Mary Wollstonecraft Shelley                

Bear in mind…

 

The two most powerful nations of the world had been squared off against each other, each with its finger on the button. You’d have thought that war was inevitable. But both sides showed that if the desire to avoid war is strong enough, even the most pressing dispute can be solved by compromise. And a compromise over Cuba was indeed found.

Nikita Khrushchev

 

The Republican Party can lead any person to believe that their promises will be fulfilled in the future. They follow the Hitler line — no matter how big the lie; repeat it often enough and the masses will regard it as truth.

John F. Kennedy

 

The point is not for women simply to take power out of men’s hands, since that wouldn’t change anything about the world. It’s a question precisely of destroying that notion of power.

Detecting deepfake videos

Detecting deepfakes by looking closely reveals a way to protect against them

by Siwei Lyu, University at Albany, State University of New York
 
Are any of these faces real? meyer_solutions/Shutterstock.com
 

Deepfake videos are hard for untrained eyes to detect because they can be quite realistic. Whether used as personal weapons of revenge, to manipulate financial markets or to destabilize international relations, videos depicting people doing and saying things they never did or said are a fundamental threat to the longstanding idea that “seeing is believing.” Not anymore.

Most deepfakes are made by showing a computer algorithm many images of a person, and then having it use what it saw to generate new face images. At the same time, their voice is synthesized, so it both looks and sounds like the person has said something new.

One of the most famous deepfakes sounds a warning.
 

Some of my research group’s earlier work allowed us to detect deepfake videos that did not include a person’s normal amount of eye blinking – but the latest generation of deepfakes has adapted, so our research has continued to advance.

Now, our research can identify the manipulation of a video by looking closely at the pixels of specific frames. Taking one step further, we also developed an active measure to protect individuals from becoming victims of deepfakes.

Finding flaws

In two recent research papers, we described ways to detect deepfakes with flaws that can’t be fixed easily by the fakers.

When a deepfake video synthesis algorithm generates new facial expressions, the new images don’t always match the exact positioning of the person’s head, or the lighting conditions, or the distance to the camera. To make the fake faces blend into the surroundings, they have to be geometrically transformed – rotated, resized or otherwise distorted. This process leaves digital artifacts in the resulting image.

You may have noticed some artifacts from particularly severe transformations. These can make a photo look obviously doctored, like blurry borders and artificially smooth skin. More subtle transformations still leave evidence, and we have taught an algorithm to detect it, even when people can’t see the differences.

A real video of Mark Zuckerberg.
 
An algorithm detects that this purported video of Mark Zuckerberg is a fake.
 

These artifacts can change if a deepfake video has a person who is not looking directly at the camera. Video that captures a real person shows their face moving in three dimensions, but deepfake algorithms are not yet able to fabricate faces in 3D. Instead, they generate a regular two-dimensional image of the face and then try to rotate, resize and distort that image to fit the direction the person is meant to be looking.

They don’t yet do this very well, which provides an opportunity for detection. We designed an algorithm that calculates which way the person’s nose is pointing in an image. It also measures which way the head is pointing, calculated using the contour of the face. In a real video of an actual person’s head, those should all line up quite predictably. In deepfakes, though, they’re often misaligned.

Defending against deepfakes

The science of detecting deepfakes is, effectively, an arms race -– fakers will get better at making their fictions, and so our research always has to try to keep up, and even get a bit ahead.

If there were a way to influence the algorithms that create deepfakes to be worse at their task, it would make our method better at detecting the fakes. My group has recently found a way to do just that.

At left, a face is easily detected in an image before our processing. In the middle, we’ve added perturbations that cause an algorithm to detect other faces, but not the real one. At right are the changes we added to the image, enhanced 30 times to be visible. Siwei Lyu, CC BY-ND
 

Image libraries of faces are assembled by algorithms that process thousands of online photos and videos and use machine learning to detect and extract faces. A computer might look at a class photo and detect the faces of all the students and the teacher, and add just those faces to the library. When the resulting library has lots of high-quality face images, the resulting deepfake is more likely to succeed at deceiving its audience.

We have found a way to add specially designed noise to digital photographs or videos that are not visible to human eyes but can fool the face detection algorithms. It can conceal the pixel patterns that face detectors use to locate a face, and creates decoys that suggest there is a face where there is not one, like in a piece of the background or a square of a person’s clothing.

Subtle alterations to images can throw face detection algorithms way off.
 

With fewer real faces and more nonfaces polluting the training data, a deepfake algorithm will be worse at generating a fake face. That not only slows down the process of making a deepfake, but also makes the resulting deepfake more flawed and easier to detect.

As we develop this algorithm, we hope to be able to apply it to any images that someone is uploading to social media or another online site. During the upload process, perhaps, they might be asked, “Do you want to protect the faces in this video or image against being used in deepfakes?” If the user chooses yes, then the algorithm could add the digital noise, letting people online see the faces but effectively hiding them from algorithms that might seek to impersonate them.The Conversation

Amazon Kingfisher
Martín Pescador Amazónico

You find these in the lowlands of both sides of the isthmus along the banks of rivers and streams. They generally don’t fish the Pacific Ocean or Caribbean Sea but will feed in brackish estuaries and lag oons and at the mouths of rivers flowing out to sea. A common bird, the Amazon Kingfisher’s range extends from Mexico to Argentina.

Los encuentras en las tierras bajas de ambos lados del istmo a lo largo de las orillas de los ríos y arroyos. Por lo general, no pescan en el océano Pacífico ni en el mar Caribe, sino que se alimentan en estuarios y lagunas salobres y en las desembocaduras de los ríos que desembocan en el mar. Un ave común, la gama del Martín Pescador Amazónico se extiende desde México hasta Argentina.

Nito and the economy: agriculture

0
rain
Water and blights: Panama’s agricultural woes are not just the trade, marketing and finance issues that grab the most attention. Shifting ranges of plant and animal pathogens and insect pests also play a role. New strains of diseases to which some of our traditional crops had been immune now can devastate farm production. Climate change has brought us erratic rainfall years within an overall 30-year drying trend. Archive photo by Eric Jackson with some bananas that had to be removed due to a fungal blight. 

Cortizo’s first moves on food and farm issues

by Eric Jackson

It has become a Panamanian political tradition for new presidents to take their first cabinet meetings on the road in order to set the main themes of what they hope to do. President Laurentino “Nito” Cortizo did this on July 2, convening a cabinet session at the National Institute of Agriculture (INA) in Divisa.

The new president is a former agriculture minister who left a PRD administration over “free trade” in farm products, a cattle breeder and former legislator from Colon province’s rural coastal circuit. He pretty much knows Panamanian agriculture, to the extent than anyone can these days.

Before he was sworn in, Cortizo met with many a foreign diplomat, head or state or cabinet minister. Read the reports of these at in the two most salient, meetings with US and Chinese representatives, on the lists of foreign policy goals were increased Panamanian beef exports to the United States and to China. (The Americans may have had an actor who played cowboys as a president in living memory, but Panama has a real cowboy of sorts.) Aside from beef exports, a number of his discussions with those from foreign governments broached the subject of bringing in technical and educational help for the farm sector.

The first cabinet meeting being at the INA, Cortizo played to the home campus crowd. He intends to upgrade the title and function to make it the Agrotechnological Institute of the Americas before the year is out. The change will likely be more than symbolic.

Were the financial moves that those Panamanian media dominated by financial and real estate sectors emphasized the most important things at the meeting? Yes, he will jiggle things around with the proceeds of the Special Interest Compensation Fund (FECI) to move more of the proceeds from that subsidized load program from the construction sector to agriculture. It will probably not be enough to fund dramatic changes in the farm sector.

AUPSA, the Panamanian Food Security Authority, an alphabet agency created in tandem with free trade with the United States, is to be abolished. It’s one of those governmental entities that, common enough in the world, was captured by the interests it was supposed to regulate.

They were supposed to regulate food imports so as not to let them drive the nation’s farmers out of business? Instead they used that power to open the gates, in the name of cheaper food but mainly in the interest of food importers. Panamanian rice production fell in particularly dramatic fashion.

They were supposed to maintain food safety standards? Instead they took whatever special interest finding that was imposed on the US government, such that foods with chemicals and hormones that are not allowed to enter Canadian or European markets came here.

So AUPSA will be no more. The imported food safety inspections and certifications will be devolved to the Ministry of Agricultural Development..

Cortizo also intends to rearrange, but not eliminate, retail food price controls. Currently there are 22 products — eggs, chicken, certain cuts of pork, macaroni noodles and so on — subject to price controls. Look for some items to be taken off of the list and others to be added.

This is a continuation of traditional policy. It runs against the objections of neoliberal ideologues who are against any state interference with markets. Varela used such measures, with a wide range of price controls and subsidies were aimed mainly at maintaining social peace. With Martinelli the supermarket baron and food importer, these measures were downgraded and twisted to benefit the economic interests of Ricardo Martinelli.

Talk of market distortions and running up the national debt are parts of discourse about consumer price controls and subsidies, including within the Cortizo political camp. But the PRD has always been for a few price controls to reduce hunger and sufficient subsidies to keep the nation’s grandmothers from having their electricity shut off en masse. Look for a presidential decree with a new list of price controlled foods within a few days. (We got a new six-month electric rate decree as one of the last Varela measures, and this raises rates a bit for upper-end consumers — mostly businesses — while it maintains subsidies for people on the lower end.)

Perhaps most ignored, but arguably most important, of the agricultural moves at Cortizo’s first cabinet meeting? It wasn’t purely for the farm sector but he said that he’s creating a  National Water Council. Huge issue, maybe in the face of climate change the biggest of them all. With the dysfunctional political patronage outfit that’s the IDAAN water and sewer authority, the Panama Canal Authority, the Ministry of Health, the Ministry of the Environment, the Ministry of Agriculture and the many local rural aqueduct systems among the institutional stakeholders to assert various dibs on water, it’s a political minefield.

 

Ah, soda limes. Maybe not the most popular citrus fruit we grow, but they thrive here. Why doesn’t Panama export more citrus products? It’s largely because we have Mediterranean fruit flies here. The technology to deal with that — releasing sterilized male flies into the environment — is well enough known. But if we did that or used any other method to rid ourselves of the medflies, surely citrus growers in places like Florida, Calilfornia and South China would find other reasons to object to imports from Panama.
