A Few Sustainability Myths

1. Sustainability is about the environment.2. Consumer choices and grassroots activism

works.3. There is no single critical piece of the

sustainability challenge.

Lemonik, 2009. Princeton, New Jersey.

Humour Me…..• Sustainability is possibly one of the most

misunderstood words in common usage.• Social structure, particularly agent types,

are powerful determinants of emergent SES patterns.

• The environment has become synonymous with “green” but we are more of a STS than an SES (something I’d like you to jot down for your Immersion Experience tomorrow).

Water is the Critical Piece• Entering the “Century of Water”• Most issues depend on water availability,

distribution and/or quality.• Transitions from common pool resource to

trade commodity.• Several “solutions” are not possible

unless water is factored in.

Trends in Water Resources

Also see White, Hinzman, Alessa, JGR Biogeosciences, 2007

• Not just availability but also quality, we can only “clean” so well.

Dealing with Future Change Requires a Paradigm Shift in “Science”

Growing evidence that technological interventions alone are not effective and may drive critical changes in water use patterns. --UN Commission on Sustainable Development (1995).1. Our understanding of the social dynamics in social ecological systems is poor.2. Our incorporation of scale is sloppy.3. Our treatment of SES is oversimplified.These may represent some of our greatest vulnerabilities to effectively coping with change.

Social Ecological Systems Hotspot Mapping

• Takes social and biophysical values and uses GIS to map the coupled social ecological landscape.

• Gives us information about where specific dynamics exist.

• Was highlighted as innovative science by NSF in Spring 2008.

Adapting to Change: AWRVI

• The Arctic Water Resources Vulnerability Index: AWRVI (“Ar-Vee”).

• Tool to assess status of water resources at the watershed scale.

• Unifies western and traditional knowledge systems.• Can be used to determine resilience and best

strategies for development.

First and only of its kind for high latitudes and local scales.

Environmental Vulnerability Indices

• EVI: United Nations Environment Programme (2001).

• UN Commission on Sustainable Development (1995).

• Global Commission on Fresh Water Resources (2004).

• Water recognized as single-most important variable in rapid change.

Emergent toolsagent-based models

Agent Based Models• Specify the rules of behavior of individuals

(agents) as well as rules of interaction• Simulate many agents using a computer

model• Explore the consequences of the agent-

level rules on the population as a whole• “Simple” models to produce complex

behaviors“How could drops of water know themselves to be a river? Yet the river flows on”

--Antoine du Sainte-Exupery

Agents and Systems• agents have connections to each other, and

form a system and operate in an environment with feedbacks

• agents behave autonomously thus they each have their own parameters (data) and behaviors

• systems change once the agents affect the threshold in a significant way

Agent Based ModelsAre not• An attempt to perfectly reproduce reality (usually)

Are• Are a tool to gain intuition about the system of interest

without needing to know all of the details• A tool to run “experiments” which cannot be performed

in real life• A tool to generate and test hypotheses about what is

occurring• A tool to refine data collection foci

Big Questions• What drives the human hydrological

system? • How do societies ‘overshoot’ their

resources (both social and physical)?• How can we learn to avoid this fate?

(Should we? If so, why?)• Move beyond rhetoric.

Developing “Real” Rules• Too often, ABMs rely on ‘artificial’ rules

(e.g., games).• Or ….”what ifs”.• It is critical that rules be derived from the

messy, real world.• Humans are not logical but they are

predictable.

"Man is a complex being; he makes the deserts bloom and lakes die."— Gil Stern

Developing Real Rules• There are three rules of thumb to

successfully developing rule sets for ABM.1. Observe your system to the point of intimacy.2. Establish colleagues in it who will assist you

with field work and data collection.3. Include modelers at the outset, not once you

think it would be “nice” to model.

Your Immersion Experience• Tomorrow you will go out into three “SES”

(two being primarily “STS”).• As yourself “who/what are the objects in the

landscape” (e.g., people, terrain, interventions, others?).

• For each of these objects, what would you need to know about them to develop meaningful rule sets?

How People Make Choices: Why We Need to Know This

People make decisions according to their life experiences,social relationships, and perceptions of what is around them.

Different people have different influence and goals that influencesother people around them: three agent types, alpha, beta and gamma.

Take Home Messages

• Many of the challenges in sustainability are not ‘fixable’ using technologies or good will.

• Agents drive the system from the bottom up and some dynamics simply aren’t pretty.

• A powerful approach to understanding consequences is to use agent based models.

• ABMs allow the unpredictable outcomes of simple choices and changes in patterns of use to be visualized in virtual worlds.
