Temporary Expert ⁄ Week 13 ⁄ EcoNet Progress

I went back to Pacific Aquarium and bought 3 silvertip tetras. Although the tank says “RARE,” silvertips along with other tetras are very common aquarium fish. They’re labeled as rare because they don’t breed in large numbers, but they aren’t rare in the wild. They’re native to the Amazon so the water shouldn’t drop below 70°F. They’re somewhat aggressive, and they school together. They’re omnivores, so regular fish food will be fine but can be given occasional larvae or other small creatures:

The food and water primers (I used spring water, then inserted the prime and stability a few hours before introducing the fish):

Acclimating to the temperature:

Supplies purchased for the filtration system. A water pump, mason jar, airline tubing, ceramic biofilter medium (little ceramic blocks that house bacteria feeding organisms as water travels through) and aquarium sealant caulk which was used to seal the holes I drilled into the lid of the mason jar for the airline tubing:

The pump pumps water into the tube that introduces the water into the bottom of the jar. Then the water rises through the filter medium and back out through an exit tube at the lid:

Temporary Expert ⁄ Week 12 ⁄ EcoNet Progress

I went back to Pacific Aquarium & Plant and spoke with an employee about what I should include in my tank and how to go about my first steps. He insisted that I don’t buy fish just yet, that I have my tank set up before doing so. I made sure that I left with something so I had him help me pick out easy to maintain plants that would inhabit freshwater at room temperature. An anubias plant:

Java moss (in the black container):

Gravel as substrate (gravel is easier for planting than sand, it holds the roots down much more easily):

2.5 gallon tank, washed:

Substrate rinsed and put into the tank:

Planted anubias and moss and filled with bottled water (room temperature, not refrigerated) from the grocery store:

The moss is held down with with a couple pebbles which probably won’t be sufficient once a pump system introduces current.I will probably have to replant as shown in this video:

Plants also need light. I knew I would go with an LED fixture because they produce far less energy and are generally cheaper. Lighting aquatic plants seems fairly complicated though:

“When concerned with supporting photosynthetic aquatic life, hobbyists should look for PAR values of LED fixtures. PAR or Photosynthetically Active Radiation designates a spectral range of light that photosynthetic organisms utilize during photosynthesis. Keep in mind that PAR values vary at different depths and distances from the LED light source. In other words, the same LED fixture will have multiple PAR values capable of supporting different species with different light requirements. Due to the relatively complex nature of expressing PAR levels and a lack of standardization, not all manufactures will provide PAR information the same way. To determine which LED aquarium light fixture is right for you, please refer to our handy LED Lighting Comparison Guide.” [1]

Since my tank is small and doesn’t require too much light, I used the abundance of LEDs I have at home to make my own fixture, adding a potentiometer so I could experiment with various colors and brightness over time. Daylight (more reds):

Night (more blues):

Next steps:

  • Pump (not required right away but would be nice to have)
  • Filter: could start with a DIY biofilter, similar to the ones they had bobbing around in some of the tanks at the store

Eventually I want to build out a custom filtration system in a way that will facilitate easy/accessible, automated water content observation/measurement.

  • Water testing kits
    • ammonia test kit
    • nitrate test kit
    • co2 test kit
    • thermometer
  • Finally introduce a fish or two: possibly a small school of guppies or similar micro fish, but not a betta in case another fish is to be added later on.

Temporary Expert ⁄ Week 10 ⁄ EcoNet Planning

1) Establish container which houses a simple ecosystem that generates toxic ammonia (which is produced by fish waste, excess food, decaying organic matter)

B.O.M.:

2) Use a biofilter to convert ammonia into nitrate

3) Measure nitrate levels with colorimeter; nitrate/ammonia/ph levels mapped to internet speed

Automatic colorimetric aquarium monitors exist and would relay data to computer, but are brand new, expensive, not accessible enough yet:

  • https://reefbuilders.com/2015/10/28/colorimeter-testing-finally-ready-breakthrough-aquarium-hobby/#
  • https://www.seneye.com/

Manual process:

I spoke to someone who used to own an aquarium with a few different species of fish, and she claimed that maintenance only consisted of changing a filter inside a motorized pump and periodic tank cleaning. In terms of data collection, the following quantifiable elements are possible:

4) Feed data into internet speed visualization

Currently don’t know of a way to gauge my internet speed considering time/money/technical feasibility constraints, so my options are:

  • Consider possibilities of browser plugins to map some aspect of web browsing experience to aquarium data
  • Feed data into a mock browsing speed visualization, possibly modeled after popular http://www.speedtest.net/ interface:

I can incorporate geographic ecological data and internet submarine cable infrastructure into this visualization.

Temporary Expert ⁄ Week 8 ⁄ Revisiting Project Idea

I’ve been stuck with where I wanted to go with this project. I’m not completely satisfied with the original project idea involving creating ads for an internet service of the future because I’ve been wanting to explore the use of physical systems (rather than purely social), a la Hans Haacke or Tim Hawkinson, to not only transform the “viewer” into “user” but to do so in a physically participatory way. I spent a lot of time brainstorming in a way similar to my daily practice routine. Stepping away from the computer screen, standing up and drawing stream-of-consciousness style was a helpful way to get myself out of this rut:

So my idea is to build a laptop cooling system that will change fan speed based on various quantifiable parts of a desktop aquarium ecosystem that I will put together, as an attempt to map my computer’s performance to the health of an ecosystem. I’ll methodically document the entire process, perhaps daily, in the form of a blog.

This system will serve to symbolize a microcosm of our larger urban infrastructure, highlighting the manufactured disconnect we’ve imposed on ourselves through it. Many thinkers, including Donna Harraway, Tim Morton, Zizek, etc, over at least the past several decades have criticized the “nature”/man-made duality, yet I feel like this psychological disconnect is still prevalent which I think leads to a sense of powerlessness over this distant “nature”. With this project I aim to obfuscate this duality and illustrate the level of agency at the hands of each individual.

A rough sketch of the concept:

The cooling pad (containing a fan or two) will be connected to my computer for power and data transfer via usb. The tank will also either have sensors transferring data to my computer via usb or I will manually observe and quantify data points by hand. Some potential measurable aspects: light, water purity, # species, water temp, growth rate… I will try to generate as much biodiversity as I can within the aquarium, but am thinking of sticking mostly to corals and underwater plant life with as few fish or animated creatures as possible for simplicity’s sake.

This successfully acts as a physical system for which I’m an active part of and it’s both conceptually sound and feasible enough that I’m comfortable moving forward with it. Although the final output won’t be participatory/interactive as documentation in the form of a blog, the act of blogging should add a performative element to the work, immersing viewers throughout the process in a somewhat time-sensitive format. This also opens me up to documenting in different ways, like maybe live streaming an IP cam into the aquarium. One concern is monetary constraints, as building an aquarium is not cheap. Another is where to install: I’m always moving around from place to place, and so I might only be able to monitor/participate with this system for so many hours a day. I also need to consider that I’ll have a bunch of living things in my hands by the time I’m finished. When will I be finished?

Temporary Expert ⁄ Week 6 ⁄ Daily Assignment

For this week’s 1-hour-per-day assignment I felt it important to step away from the computer while experimenting with my idea to engage it in a different way.

Day 1 (Thurs)

Today I went to the Queens museum to see the 1964 Panorama of the City of New York:

…and the 1938-1939 Relief Map of the New York City Water Supply System:

The city’s watersheds are highlighted. Catskill & Delaware watersheds:

Croton watershed:

The plaques along the perimeter of the map added some interesting numbers to the visual:

Day 2 (Friday)

After too much stalling on what to do, I decided to just start doing something and let it develop over time. So I mapped out the Yangtze River watershed in China, one of the more interesting watersheds I’ve looked at this semester. It encompasses about 20% of China, which is a considerable size even on a global scale:

I drew the map and river on paper, then overlaid the watershed area in yellow on transparent paper. At the mouth of the Yangtze River is Shanghai:

Day 3 (Saturday)

Next I drew the smaller rivers / tributaries that make up the entire Yangtze River catchment system:

Along the Yangtze River is the massive Three Gorges Dam, which is the world’s largest power station, producing hydroelectric power. This led me to mapping the locations of all currently operating hydroelectric power stations in this watershed:

Day 4 (Sunday)

On day 4 I finished mapping the hydroelectric power stations:

Day 5 (Monday)

I read about a study that concluded that the benefit for preserving the watershed’s forests helped flow more water through the dams thus producing more electricity was greater than the revenue generated from clearing them for timber production, so I decided next to map the proliferation of forests in the area:

As in most parts of the world, tree loss (orange) far exceeds growth (black).

Day 6 (Tuesday)

After this I thought it would be interesting to map the consumption / demand of the water (darkest: >1000/km sq; lightest: <= 1/km sq):

Day 7 (Wednesday)

TBD

Temporary Expert ⁄ Week 5 ⁄ Topic 1: Ecosystem Services, Project Proposal Draft 2

Link to slide deck here (Dropbox)

Human society can no longer treat the environment as a ‘free good’ to be exploited without consequences. As the limits to our consumption habits begin to materialize along the horizon, we must reconsider fundamentally how we think of ourselves in relation to the ecosystems we are destroying yet rely on so heavily for survival in order for our children to survive and thrive in a world worth living in. All of humanity will ultimately benefit from working to reshape our society’s functions to consider not only its efficiency but also its resilience in providing us with such security and comfort well into the future.

One of the major opportunities for positive change toward a more resilient society involves harnessing a better understanding of how the functions inherent in our local ecosystems can provide us with services that are often more beneficial than their man-made counterparts from an economic standpoint, which yields further incentive to restore and sustain the biodiversity that enables our ecosystems to provide us with these services, from the provisioning of food, water, timber and natural gas to the regulating of our air and water purity.

In order to harness such an understanding I’m proposing to create artifacts of a possible future of the global internet infrastructure that would, by design, close the perceived gap between the consumption habits of “end users” and the resulting impact on the environment. The landing stations for the submarine fiber-optic cables that carry our web traffic around the world would be reconfigured with new data transfer technology combined with extensive complexity and environmental research that would result in an web paradigm where web connectivity speeds are directly based on the biodiversity of the landing station’s local ecology. Not only would this have all internet users thinking and caring about their local ecosystems, but also of those in countries the world over.

The artifacts would most likely consist of mock advertisements that take place in major cities and on the internet. The ads would lead to a corporate-looking EcoNet landing page with further detail about the concept. Users engaged enough to have visited the site could perhaps also be provided with some sort of platform for feedback or discussion: a forum, an IRC, surveys, a “contact us” form, or even a temporary phone line with an operator listening to and recording incoming calls.

The implementation of ecosystem services into our infrastructure can result in a kind of environmental manipulation that can have unforseen consequences. Through these objects I’ll attempt to expose possible social, economic, or ecological downsides, attempting to provoke questions about what it means to intervene in such complex systems. For example, in “Ecosystem Services: From Concept to Practice” Jetske A Bouma and Pieter JH van Beukering state that “the key characteristic of ecosystems is that they consist of public or “common-good” resources.” So what does it mean to privatize these resources? What does it mean for the poor, who are more likely to rely on these common-good resources rather than societal infrastructures (like grocery stores or purified tap water)?

Temporary Expert ⁄ Week 2 ⁄ Topic: Ecosystem Services ⁄ Project Ideas

Question:

Does the internet’s physical global infrastructure directly (or at least indirectly) benefit from any ecosystem services? Can it? How?

Inspiration:

  1. Evan Roth, “Internet Landscapes
  2. Trevor Paglen, “Deep Web Dive
  3. Gustavo Romano’s “Madonna, Water Maps, & Botannical Gardens” essay (from Net Art Latino Database)
    • Building off the idea of “technological determinism” (the internet attention economy as the market which decides what content survives and what disappears forever)…
    • “The digital medium makes no allowance for marking the passage of time… either it’s here or it’s gone.” … Can these digital cultural assets be sustained by making sure the internet itself is built on a sustainable infrastructure?
  4. Niklas Roy, “Pneumatic Computing – Flop or Future?

Approaches:

  1. Mapping
    • Map the major cables/hubs of internet infrastructure across the world
    • Map the ecosystems in these areas and the accompanying local services in use
    • Identify matching supplies and demands among these two global systems
    • Present maps/diagrams visualizing how the services would interact at a local level
      • For an audience of internet users most-likely oblivious to its physical infrastructure and to the concept and complexity of ecosystem services
  2. Research
    • Learn what comprises the internet’s physical infrastructure
      • What natural resources does it demand?
        • How are these resources sustained through ecosystem services in other systems?
      • How does it connect to the power grid / other infrastructures?
      • How does one come up with / discover new ecosystem services that can be taken advantage of?
      • Present this research as raw documentation
        • For an audience of internet users most-likely oblivious to its physical infrastructure and to the concept and complexity of ecosystem services
  3. “Design fiction”
    • Inspired by Niklas Roy’s project above, the proposed question can be: how can the internet infrastructure be restructured to incorporate existing ecosystem services?
    • Learn what comprises the internet’s physical infrastructure and identify alternatives involving existing ecosystem services
    • Presentation can be in the form of a video, a series of images (photoshopped, CG, illustrations)
      • For an audience of internet users most-likely oblivious to its physical infrastructure and to the concept and complexity of ecosystem services

Texts:

Ecosystem Services, Ronald E Hester & Roy M Harrison, 2010

  • Preface
  • Ch1: An Assessment of Ecosystem Services and Biodiversity in Europe

Ecosystem Services: From Concept to Practice, Jetske A. Bouma, Vrije Universiteit, Amsterdam and the Netherlands Environmental Assessment Agency (PBL) , Pieter J. H. van Beukering, & Vrije Universiteit, Amsterdam, 2015

  • Ch1: Intro
  • Ch4: Mapping ecosystem services

Ecosystem Services — Preface

“Ecosystem services” born out of visible/attainable limits to natural resources. This first led to ‘technological solutions’ like

  • ‘End-of-pipe’ sewage/waste clean-up
  • Increases in agricultural production via
    • Plant breeding
    • Pesticides
    • Chemical fertilizers

Then came realization that these approaches are not sustainable, which led to more holistic thinking to environmental management (i.e, a life-cycle approach to manufacturing products for mass and energy flows at all points in the process).

Historically, society has treated the environment as a “free good” to be exploited without consequences. Thinking in terms of ecosystem services allowed full impact to be recognized.

Ecosystem service = nature doing a ‘service’ for human society (i.e., small villages dumping liquid waste into local water courses, rendering the water not harmful via self purification processes).

“Our most basic needs for food, water, and air are supplied through ecosystem services which society interferes with at its peril.”

“All ecosystems deliver a broad range of services, and managing an ecosystem primarily to deliver one service will reduce its ability to provide others.”

Ecosystem Services — Ch1: An Assessment of Ecosystem Services and Biodiversity in Europe

The ecosystem is the level at which “key processes such as carbon, water and nutrient cycling and productivity are determined” and measured. These processes determine how the world functions and are how services are identified.

Ecosystem Services: From Concept to Practice — Ch1: Intro

“…policy-makers and practitioners are struggling to implement the concept in practice. An important reason for this science–policy divide is the lack of an interdisciplinary framework” (p3)

“the relationship between biodiversity and ecosystem services is complex and non-linear. Although biodiversity forms the basis for all ecosystem services, biodiverse ecosystems do not necessarily provide more ecosys- tem services than ecosystems that are less diverse.” (p6)

Less biodiversity = less resilient ecosystem (threatens availability of ecosystem service in long run)

Ex: “drive towards monoculture food production. By increasing the productivity of food production, soil formation processes are diminished and disease regulation is reduced.” (p6)

“it is clear that the risk of ecosystem collapse is real”(p8)

“…the costs of replacing ecosystem services by man-made capital are often substantial and replacing natural capital by man-made capital usually greatly increases energy use as well.” (p8)

“Perhaps the question should not be to what extent improving the health of ecosystems improves human well-being. Instead we need to ask ourselves how the provisioning of ecosystem services can be safeguarded for generations to come.” (p8)

“protecting biodiversity may have implications for the poor. For example, Cernea and Schmidt-Soltau (2006) indicate that protected area establishment has increased poverty in parts of Africa as local communities were displaced.”(p9)

“…it is difficult to protect the ecosystem and alleviate poverty at the same time.”(p10)

“The key characteristic of ecosystems is that they consist of public or “common-good” resources.”(p11)

“an ecosystem delivers ecosystem services at a local, regional, and sometimes global scale. For example, a forest provides landscape and fuel benefits at a local level, yet the benefits of water purification and retention are regional and the benefits of the habitat function and carbon sequestration are global.”(p13)

“the concept of ecosystem services implies a shift from resource-focused policies (e.g. water, energy) to ecosystem-focused approaches (e.g. forests, wetlands) taking into account service delivery at multiple scales.”(p14)

Ecosystem service criticism exists over:

  • The focus solely on benefits
    • “Clearly, ecosystems have more functions than the delivery of benefits for humankind only, and focusing only on benefits carries the threat of ignoring the other important roles that ecosystems fulfill.”(p14)
    • “debate about the ‘commodification’ of ecosystem services”(p14)
      • “economic valuation of ecosystem services and introduction of market mechanisms is making ecosystem services tradable similar to other commodities”(p14) like timber and soy.
  • Lack of attention for distributional issues
    • “…effective governance of ecosystems requires attention for social justice and the distribution of ecosystem benefits.” (p15)
  • Simplicity of the stock-flow relation underlying the concept
    • “…the concept is too simplistic to be used for policy-making as it hides great uncertainties about ecosys- tems and the delivery of ecosystem services that need to be better understood.”(p15)
    • proposal of alternative concept: “ecosystem resilience”: “instead of valuing the current societal benefits of ecosystems, the focus should be on ensuring the long-run resilience of ecosystems, with the implicit suggestion that this will benefit society in the long run.” (p15)

Ecosystem Services — Ch4: Mapping Ecosystem Services

“…the supply of ecosystem services is not homogeneously distributed across space” via “variability in plant functional traits + other environmental conditions” (p65)

“demand of ecosystem services dependent upon location as well” via “spatial variation in socioeconomic conditions” (p65)

Mapping is used to “understand the role of this spatial variation”. (p65)

Regulating service = most commonly mapped (esp climate regulation)
Provisioning = second most commonly mapped (esp food production)

Why do ecosystem services get mapped?

  • To make inventory of current supply
  • To determine priorities
  • To perform a trade-off assessment
    • “different stakeholders have different needs, and structuring the landscape to meet one of the objectives will have impacts on other ecosystem services”
  • To determine changes in service supply/demand over time

What exactly gets mapped?

  • Potential supply
    • “the capacity of the ecosystem to provide ecosystem services without considering the demand for an ecosystem service.”(p68)
  • Actual Supply
    • “amount of the ecosystem service that is used by humans, i.e. the flow of an ecosystem service.” (p68)
  • Demand for service
    • “requirement for an ecosystem service by humans”(p68)

Maps can be based on:

  • Occurance
  • Quantities
  • Values (sociocultural or monetary)

How are ecosystem services typically mapped?

5 methods:

  1. Look-up tables
  2. Expert knowledge
  3. Casual relationships
  4. Extrapolation of primary data
  5. Regression models
