Possible futures for the Yahara Watershed

The Science of Future Thinking

“People are embedded parts of the biosphere and shape it, from local to global scales, from the past to the future. At the same time people are fundamentally dependent on the capacity of the biosphere to sustain human development.” -- Carl Folke, Stockholm Resilience Center

Future thinking is important because…

But sustaining nature and human development is a complex problem:

• Uncertainty is high.• Time frames of environmental change

span many generations.• People will reach different conclusions.• Multiple solutions are “good enough.”

To approach complex problems, we can

• Assume uncertainty is large, changeable, and co-created by people and nature.

• Emphasize the diversity of perspectives.• Stress learning by individuals and groups.• Expect the unexpected.

“While the future is uncertain and much of it is beyond our control, we can control many aspects of it. We choose our future: we create it by what we do or fail to do.”

– Wendy Schultz, futurist

Importantly, we must recognize we can make choices about the future.

TIME

Principle 1: Throughout time, we can make choices that will affect future outcomes.

Principle 2: We can think about what might happen as a result of these choices, highlighting alternative pathways to alternative futures.

Scenarios help us consider these pathways• Scenarios are provocative, plausible stories about the future

with contrasting social and environmental conditions.• They explore questions of “What if?”• They facilitate long-term thinking.• They help us learn ways to address change and vulnerability.

To 2070

Today

Principle 3: We can anticipate future consequences of the alternatives. Scenarios help us with this, too.

The future is already here; it’s just unevenly distributed.

The complex problem:How could changes in land use, climate, and human

demand impact ecosystem services, or natural benefits, for future generations in the Yahara Watershed?

Yahara River Watershed

Long-term Changes and Challenges• Intensification of dairy agriculture

– Trend towards fewer farms and cows but WAY more milk (and manure) per cow

– Main source of water quality impairment

• Increasing demand for biofuels

• Urban development– Increase in impervious surfaces lake flooding– Loss of agricultural land concentration of manure

• Changes in climate– Increase in annual precipitation– More frequent heavy rainfall events

These changes span generations

Major Changes in the Yahara Watershed1800-present

A consequence: persistent water quality problems

Nutrient pollution in lakes and streams

– Multiple non-point sources (manure, agricultural fertilizer, urban, erosion)

– Algal blooms, public health & aesthetics issues

– 33 years of reduction efforts, but undetectable reduction in P-loading to lakes

What futures for water and people are possible, given these long-term challenges?

What is a desirable future, and what solutions can lead us there?

Yahara 2070’s creation story

Two Generations

Stories connect us with future generations.

In the world there are lots of perspectives.

We sampled perspectives from the Yahara Watershed through interviews and workshops,

clustered them into themes,

and condensed them into a few stories.

The Stories

Tentative Name:

Nested Watersheds

Abandonment & Renewal

Accelerated Innovation

Connected Communities

Dynamics: Adaptation Transformation Adaptation Transformation Key Factor in Change: Government Inaction Technology Values

Nutshell:

Government intervention

maintains nature’s benefits

Disaster decreases population, leads to

reorganization

Massive growth in technology businesses,

including green tech

Global shift in values toward sustainability

Name:

Each based on a different set of human choices and biophysical events

The “Atoms”

Translations of the stories into numbers that a

biophysical computer model can understand

Models

Narratives

Climate Changes

Nested Watersheds

Landscape Changes

2010 2070

Model results: Ecosystem services in the Yahara

• Food production (for animals and humans)• Biofuel production (grass feedstocks)• Climate regulation (ecosystem carbon storage)• Freshwater supply (groundwater recharge)• Flood regulation (lake levels, flooding extent)• Groundwater quality (nitrate leaching)• Surface water quality (P loading to lakes)

Stories + Atoms = Implications for future human well-being

Accelerated Innovation Nested Watersheds

Connected Communities Abandonment & Renewal

The scenarios illuminate vulnerabilities we should consider preparing for.

Example: Impacts of extreme flooding– The biggest flood

in Abandonment & Renewal, 2031

– Similar to 2008 storm that flooded Lake Delton, WI

The four scenarios together highlight choices and tradeoffs…

What do we want—or need—the watershed to provide?

What is biophysically possible and socially acceptable?

What choices will allow us to handle shocks and build resilience?

…and present cross-cutting questions for public discussion.

What are the worst threats, and how can we avoid them?

What are the best ideas or results, and how can we achieve them?

What is a desirable future, and how do we get there?

Ultimately, the scenarios can help stimulate conversations about our vision of a desirable and possible future

“If you want to build a ship, don’t start with collecting wood, cutting the plank and assigning work, but awake in people the longing for the wide and open sea.”
