Drone Wars: Protecting Endangered Animals

WWF_droneDespite anxieties associated with drone use – most of which have to do with domestic surveillance and warfare – there are numerous positive uses for the technology. Whether it is keeping an eye on oil rigs, monitoring underground cables, spying on drug or human traffickers, or ecological surveillance, there are plenty of uses for unmanned aerial vehicles beyond warfare and invading privacy.

In Namibia, for example, where poaching remains a problem, drones may be the key to protecting the endangered rhino and elephants. Namibia’s Ministry of Environment and Tourism, along with the World Wildlife Fund and funding from Google, have partnered to invest in drones that can track rhino and elephant herds. Through the use of these drones, the researchers were able to follow herds and alert law enforcement in the event the animals were being targeted by poachers.

WWF_drone_graphicIn field tests conducted in two national parks in November 2013, drones with 2-metre wingspans flew day and night missions to video black rhino herds and send live footage to poacher-tracking rangers on the ground. Smart radio tags attached to rhinos allowed the drones to home in on each herd’s current location. Crawford Allan, leader of the Wildlife Crime Technology Project at WWF, put it as follows:

We broke new ground using technologies that have never been integrated before to provide powerful wildlife protection.

The MET says it will now press ahead and deploy drones in areas of Namibia where rhinos and elephants roam. WWF estimates that illegal poaching in Africa nets criminals $10 billion each year – with some 22,000 elephants killed annually and 1000 rhinos killed last year in South Africa alone. Their efforts are also thinning out elephant and rhino populations and putting the entire ecosystem at risk.

conservation_rhinoAlthough the drone program should help prevent poaching in Namibia, the issue is widespread across Africa. It’s not clear whether a similar program will be rolled out elsewhere, but any success incurred in Namibia to stop poaching will set a precedent others are sure to follow. And, it should be noted, this country and the WWF are hardly alone in wanting to adapt UAV technology to the goal or ecological or species conservation.

In many ways, MET’s use of high-tech to protect wildlife echoes that of Technology For Nature (TfN), a joint venture of Microsoft Research in Cambridge, UK, University College London and the Zoological Society of London. Led by Lucas Joppa and Siamak Tavakoli at Microsoft, TfN is getting similar drone and animal-tagging projects off the ground in the Republic of the Congo, the Seychelles and Zambia.

conservation_drones_inlineAnd then there’s Conservation Drones, a non-profit organization co-founded by Serge Wich – a professor in primate biology at John Moores University. Made up of researchers and technologists, the group’s mandate is to spread drone use around the world for the sake of conservation. So far, they have worked with conservation groups and governments in Nepal, Indonesia, Gabon, and Greenland, and Wich hopes to visit more countries later this year.

According to Wich, the challenges to conservation go beyond simply monitoring endangered animals, which may be in too few number to accurately keep track of. There’s also the matter of the rough and vast terrain, which can be very difficult to physically cover. Drones are a big game changer in this game. By covering large areas in surveys, doing it repeatedly, and automating some of the analysis, aerial vehicles can track wildlife in a more comprehensive and efficient way.

conservation_dronesThanks to the growth of commercial aerial drones in recent years and the significant reduction in price, the technology is becoming much more affordable and user-friendly. The kits Conservation Drones uses cost no more than about $3,000, and the latest version has an open-source autopilot platform from California, along with a GPS tracker and altimeter. It’s then fitted with still cameras or video. As Wich himself put it:

The potential is huge to allow people to do very efficient data collection on a variety of issues that are important for conservation. We often struggle determining how many animals there are, where human encroachment is occurring. There are an enormous amount of ecological questions we can address with these systems.

To set a flight path, Wich simply plugs in a few points on a Google Map, then launches the drone by hand. The battery-powered module can fly for up to an hour, and cover a maximum distance of about 40 km (25 miles). The drones offer an aerial view, allowing Wich and his colleagues to get a close-up view unobscured by clouds. The next step is to improve the analysis of the images that come back.

conservation_drone_mosaicConservation Drones is now working to automate the counting process, and build up picture-maps by stitching hundreds of images together (like the one above). It also wants to create 3-D model environments, providing a sort of living inventory of what’s been destroyed and what remains. Long-term, it is hoped that governments all over the world with conservation problems will used the detailed software and aerial drones to keep tabs on their endangered animals and habitats to ensure their protection.

Several other groups are also pioneering drones-for-conservation, notably the World Wildlife Fund working with Google, the International Anti-Poaching Foundation, led by Iraq War veteran Damien Mander, and ShadowView, a group out of the Netherlands. Poachers beware. In addition, the Zambian Carnivore Program will be testing a pair of VHF-radio-equipped quadcopter drones in the US soon and he hopes to begin testing the miniature aircraft in Kafue National Park in Zambia in May.

Arcology in Popular Culture

arcologyHello and good evening. Welcome to the third and final installment in my Arcology series, addressing the use of the concept in various popular culture sci-fi franchises. After researching the term and learning all about Paolo Soleri and the concept he created, I’ve come to see that his vision of future cities where the needs of ten of thousands of inhabitants could be met in sustainable ways helped to inspire the a great deal of speculative fiction.

Here are just a few examples that I can recall or have been able to find…

Chi-Town:
Many years ago, some friends of mine came to me with a new RPG by the name of RIFTS. A sort of sci-fi/fantasy crossover, the game was set in a post-apocalyptic world where inter-dimensional gateways, known as “Rifts” had led demons, monsters and mythical creatures into our universe, where they began wreaking havoc. After many years, several new nations emerged, the most powerful of which were the Coalition States, a dictatorship dedicated to fighting the invasion and reestablishing order.

The seat of this government is a large arcological city known as Chi-Town, which was built on the ruins of Old Chicago (hence the name). A self-contained city, the structure is somewhere between a pyramid and a rectangle in terms of shape. And of course, its hierarchical structure mirrors the social divisions at work within. The lower levels are the most densely populated, have the most indigents, and experience the most crime, while the upper levels are more spacious, opulent, and well-maintained.

In addition to being a fortress city and a safe haven for human beings in the ruins of the United States, Chi-Town is also a fitting example of an arcology. Within its walls, all things, including water, air, food and energy, are providing by internal systems and subject to recycling and treatment. Again, the issue of quality is dependent on where someone finds themselves within the structure, but the principle is still the same. In a world that has been devastated and rendered inhospitable, the response was to create a mega-structure that could both shield and provide for its many, many inhabitants.

Coruscant:
coruscantFans of the Star Wars franchise are certainly familiar with this planet-encompassing city, even before it was featured in the prequel trilogy. As the capitol of the Old Republic, Empire and New Republic, respectively, it has a very long history of habitation, and a very sizable population! As a result, its architects and engineers had to get very creative with the use of space on this planet, and several massive buildings were the result.

In truth, Coruscant was not so much a single city as thousands upon thousands of interconnected arcologies that ran across its surface. These various mega structures measured roughly a kilometer in height, dwarfing even the nearby mountain chains, and housed hundreds of thousands of residents each. In addition, the need to feed and provide for the staggering number of inhabitants required that every structure come equipped with a massive network for recycling water, waste and food.

Officially divided into megablocks and levels, every section of the city had its own means for providing food, water, and manufactured goods. This in turn required the presence of internal systems for processing air, drinking water, food waste, human waste, and industrial waste from its manufacturing warrens. In addition, in the sub-city where natural light did not reach, holograms and artificial lights were also built in to the environment to provide its inhabitants with illumination. In addition, it is also indicated in a number of sources that agricultural operations were housed in various sections and relied on recycled water and either artificial or filtered light.

Though food and waste still required a great deal of shipping and processing, which resulted in a staggering amount of transport traffic, much of the cities needs were taken care of by means of these internal measures. This ensured that the roughly three trillion inhabitants of the planet would never become wholly dependent on outside sources of food and goods, as well as ensuring that pollution and harmful waste wouldn’t accumulate to disastrous levels.

Habitats:
In the works of Peter F. Hamilton, particularly the Night’s Dawn Trilogy, much attention is given to the kinds of futuristic living spaces humanity will someday occupy. For starters, there is planet Earth in this future setting, which is so overrun by human beings that all cities have evolved to become self-contained arcologies. On top of that, there are what’s known as “Habitats”, floating megacities which exist out amongst the stars.

One of the most notable of these is Eden, the first ever habitat to be created, and in orbit around Jupiter. As the closest thing to a capitol in the Edenic culture, it was built using Bitek – aka. Biotechnology – which resulted in a living structure that was psychically linked to its inhabitant through a process known as affinity.

Here, as with other Habitats, the structures are massive, measuring several kilometers in length and width. In addition, each is entirely self-supporting, providing food, water, electricity and artificial gravity to its inhabitants. The latter is created through the rotation of the whole structure around its axis, while a central light tube which runs the length of the station provides light. Food and water are produced via biological processes and are recycled to ensure minimal waste, which in turn is also processed and converted for later use. In addition, interstellar material is frequently intercepted by the habitat and converting into any and all goods which its people require.

Ultimately, the only thing a habitat needs is a supply of external matter which it will use to grow and mature during its formative cycle, and an external power supply to maintain its functions. This is last necessity is provided by a series of external conductor cables which grow on the outer hull of the structure where they are positioned to pick up charges. Due to the rotation, these cables then cross the electromagnetic flux of the nearby gas giant and thus produce electrical energy. All is provided and nothing goes to waste. A true future city!

Urban Monads:
The setting of Robert Silverberg’s fictional study in overpopulation, The World Inside occurs almost entirely within the hyperstructure known as Urban Monad 116. As the name implies, this massive, three-kilometer high city tower is but one of many on the planet, which have become necessary now that war, disease and starvation have been eliminated, but people still continue to procreate without restriction. During the telling of the story, which takes place in 2381, the total population has reached 75 billion.

Much attention is given in the novel to how urban monads (or “Urbmons”) are arranged and meet the needs of their 800,000 respective inhabitants. For starters, groups of these skyscrapers are arranged in “constellations” so that one’s shadow does not fall upon another. Each Urbmon is divided into 25 self-contained “cities” with 40 floors each, in ascending order of status, with administrators occupying the highest level with population and production centers sequestered below.

In order to see to the needs of this rapidly expanding population, all arable land not currently occupied by Urbmons is dedicated to agriculture. However, within the Urbmon communities,  resource management still counts for a lot, with all foods and goods being held in common and the people expected to share them. Beyond that, however, sustainability is not exactly the name of the game, as the right to engage in free expressions and sex and reproduction are considered the highest forms of activity.

Hence, Silverberg’s Monads break a few of the basic rules of arcology, but the basic premise is still there. Designed to house a rapidly expanding population that threatens to overpower the Earth, Urbmons take advantage of the concepts of megastructures and 3-D planning to ensure that every living soul is housed and provided for. Now if they could just stop reproducing so much, they’d be in business!

Tyrell Corp Building:
Though not specified as an arcology in the strictest sense, I couldn’t possibly make this list without including the infamous Tyrell Corp building. I mean just look at the thing. Imposing, Gothic, and very, very big! And let’s not forget highly symbolic, as the design, size and scale of the thing was meant to evoke the feeling of awesome power that the corporation held.

Though not much is made clear of what life inside the building is like, it was clear that it was made up of many, many levels and sections, each of which fulfilled a different purpose. At ground level, the building was protected by automated systems which “fried” one of the story’s Nexus 6’s when they tried to break in. Farther up are various industrial areas that are dedicated to the production of the company’s Replicants, as well as office spaces and administrative areas. Another Replicant was detected in one of these sections, right before it shot the man who had detected it – Detective/Blade Runner Holden.

At the apex of the building is the living area for Tyrell and Rachel, the experimental Nexus unit that was modeled on his niece. This level is accessible only by elevator which runs along the outer edge of the building, and can only be accessed by authorized personnel. Here, Tyrell lives amidst opulent surroundings, vast marble floors, stone columns, and even an aviary for his pet owl. Although it is not explicitly said, it appears that Tyrell spends all of his time here, never venturing to the outside city or to another domicile. Hence, we can only assume that all of his needs are seen to here, even if everything he consumes is flown in and all the waste produced is shipped out.

Mega-City One:
judge-dredd-megacity-oneThe setting of the Judge Dredd franchise, Mega-City One is essentially a massive urban sprawl which stretches from the Quebec-Windsor City corridor to the peninsula of Florida in the south, growing out of the Northeast Megalopolis to occupy Southern Ontario the entire Eastern Seaboard. And in addition to stretching so very far and wide, this city is also made up of arcologies in order to see to the needs of its roughly 800 million inhabitants.

These arcologies come in the form of huge apartment blocks which house roughly 50,000 people each. Within each block, citizens are attended to by automated systems which recycle everything, waste, water, and even food. As for manufactured products and consumer goods, these too are largely created in industrial warrens that housed within specific blocks.

This system of every need being handled by automated systems and machines was designed to ensure that the survivors of the nuclear holocaust (aka. The Apocalypse War) would be tended to. However, it had the unwanted side-effect of also leading to rampant unemployment and listlessness amongst the population. This is one of the main reasons why Mega-City One is awash in petty criminals and organized crime syndicates. This, in turn, is what led to the creation of the Judicial System and its army of Street Judges.

Trantor:
Perhaps the first example of a ecumenopolis appearing in fiction, Trantor went on to become a source of inspiration for many science fiction franchises. And according to Asimov, it represented what he believed would be the end result of industrialization and human technology, which was an encapsulated population living in cities that spanned entire planets.

Consisting of buildings that reached deep into the ground and reached several kilometers above sea level, Trantor was home to roughly 45 billion people at the height of the Empire. It’s overall population density was 232 per km², and just about every human being was dedicated to the administration of the Empire or the needs of its population. Though by the time of Foundation, most of the population’s needs were met by importing food and basic necessities from every major planet in the region.

However, according to Prelude to Foundation, Trantor’s basic food needs were once fulfilled by the planet’s vast system of subterranean microorganism farms. Here, yeast and algae were produced as basic nutrients, which were then processed with artificial flavors to create palatable food sources. These farms were tended to entirely by automated robots, but their eventual destruction during an uprising forced the planet to turn to external sources

The Sprawl:
Also known as the Boston-Atlanta-Metropolitan-Axis (or BAMA for short), this mega-city is the setting for the majority of William Gibson’s Sprawl Trilogy. Encompassing the classic cyberpunk tales of Neuromancer, Count Zero, and Mona Lisa Overdrive, the concept of arcology is raised on numerous occasions in reference to the massive apartment blocks that make up the city.

On such building is Barrytown, an arcology in the projects which is the setting for much of the second novel. Throughout the novel, it is indicated that the people here generate their own food, such as the catfish farms that exist near the top of the building. Trees are also grown on specific levels to generate oxygen which is then fed into the building’s air recirculation system. And finally, mentions are made that there are air turbines on the roof of many project buildings which generate electricity for the inhabitants.

Being such a massive, futuristic city, the Sprawl features many such structures, all of which are described as giant skyscrapers that house tens of thousands of people within their tall frames. And ultimately these are all contained beneath the a series of geodesic domes which encapsulate the city and generate peculiar weather patterns consistent with micro-climates. In this way, the BAMA itself is one massive structure, containing hundreds of millions of people under a single roof.

Zion:
The last remaining free city that humanity could still call home, Zion was not a megastructure per se, but nevertheless fit the definition of an arcology to a tee. An underground habitat that was home to roughly 250,000 men, women and children, Zion was the picture perfect representation of a self-contained living space that handled all the needs of its inhabitants internally.

As Councilman Hamann intimated in Matrix Reloaded as he and Neo walked along the Life0-Support Level, all of Zion’s needs are attended to by machines. These provide power, heat, water, and are constantly recirculating and recycling them.  Meanwhile, food seems to be either grown in special hydroponic areas, or synthesized in bio facilities dedicated to that purpose.

In terms of its internal layout, Zion is ovoid in structure and consists of many levels, each with its specific purpose. At the apex rests the Dock, where Zion’s army of hovercrafts are stationed and automated defenses protect against intruders. Beneath that are the Gathering Spaces, where new arrivals who have not yet been assigned permanent quarters are temporarily housed.

The middle section is entirely dedicated to habitation, made up of family quarters, and the Council Chambers which houses Zion’s ruling council. The lower levels consist of the Meeting Hall, Life-Support Level, and Geo-Thermal Generation, where the cities power and heat are supplied from. At the very bottom lies the Temple, a large cavern where religious gatherings are held and people gather to hold celebrations and mourn the dead. This area also serves as a last defensive position in the event that the automated defenses were destroyed and the Dock overrun. This of course became the case in Matrix: Revolutions when the machines attacked Zion and nearly destroyed it.

What did I tell ya? Clearly, the idea has made the rounds since Soleri’s time. And in all likelihood, we are sure to see the concept popping up more and more as the problems of overpopulation and environmental impact become more acutely felt. There are some who might express disgust and even fear at the idea of living an encapsulated existence, but given the growing need for sustainability and places to put people, will we really have a choice? One can only hope!
