Social Complexity in 3D Lecture: http://youtu.be/eYe0QrFpQ6c
when modeling phenomena in science and engineering, we begin with simplified, incomplete models. As we examine things in greater detail, these simple models become inadequate and must be replaced by more refined models.
in a graph database what you sketch on the whiteboard is typically what you store in the database.
Following are my identified values (overarching commitments) in four common value domains. This is a course activity from the online course “Becoming a Resilient Person” at edX.
- Study Geospatial Information Science
- Contribute work to improve community
- Improve water systems and access to clean water/sanitation
- Document people and places through creative multimedia
- Integrate into a network of professionals
- Experience and enjoy nature
- Collect, organize, and share multimedia
- Be a caring and committed father
- Bring peace to family relationships
- Be a loving and committed partner
- Build lasting friendships
- Exercise regularly
- Pursue a low impact lifestyle
- Eat nutritional food
- Study regularly
- Complete tasks/projects that I start
Earthcare in Raahe
Cleaning up the shorelines
Activists demonstrate selfless love for nature
As part of the process of becoming resilient, I need to identify values and specific roles in which to apply my values. These contexts are known as value domains. As of this writing, I am able to identify the following value domains and roles, in which I need to clarify personal values:
- Personal health/wellbeing
Human population development
Human populations often grow near water sources. More recently, human populations have been developed in arid locations:
- Los Angeles
- Las Vegas
Water projects deliver water from remote locations to arid communities:
- Bureau of Reclemation
- Book: Cadillac Desert
Energy and material costs of moving water are significant. Water is sometimes pumped up slope, over hundreds of miles, and from many sources.
Competition and Conflict
Native populations and local residents have historically asserted rights to local water sources. Additionally, water quality can be contentious from downstream communities that feel quality has been degraded by upstream uses.
- Texas v. Oklahoma – Supreme Court ruled that Texas does not have right to Oklahoma water
- China – undertaking major projects to convey water from South to North China, large water projects (3 Gorges Dam)
- Owens Valley – local residents/farmers asserted right to water over Los Angeles
- United States v. Mexico – Colorado River water is significantly depleted before getting to Mexico
- Egypt and Ethiopia – Egypt has rights to water superseding water rights in Ethiopia
- Singapore and Malaysia – Singapore relied on water from Malaysia; focused on water re-use/reclamation (water treated to high level put back in water system), now “water independent”
Cooperation and agreements
Water treaties are created between countries/populations to make agreements about water usage and passage. This brings cooperation between people, nations, etc.
There are several significant steps in water treatment, including:
- Filtration – e.g. Biosand
- Coagulation & Flocculation
- Biological degradation – aeration, microbial digestion, etc. (if wastewater)
- Settling / Sedimentation
- Removal of excess nitrogen and phosphorous
- Discharge (if wastewater)
- Disinfection (if for drinking) – UV, chlorination, etc.
