Nature’s Survival Strategies Follow Three Principles of Sustainability

1. Reliance on solar energy• The sun provides warmth and fuels photosynthesis

2. Biodiversity• Astounding variety and adaptability of natural

systems and species

3. Chemical cycling• Circulation of chemicals from the environment to

organisms and then back to the environment• Also called nutrient cycling

We rely on solar energy

Ok, Ok, there are some insignificant exceptions*

Where do “closed systems” like fish tanks get their energy?

Diversity Makes a System Stronger

Diversity allows natural systems to function since every player has a particular role. When one player drops out or is unable to fulfill its role AND if there is no other player around to step in, system function is compromised.

Diversity Makes a System Stronger

Beginning in 1890s, and booming after WWII Detroit was one of the manufacturing capitals in America. However, with dramatic decreases in manufacturing demand brought on in part by cheaper production overseas, today Detroit has been considered a “collapsed city”.

1-1 What Are Three Principles of Sustainability?

• Concept 1-1A Nature has sustained itself for billions of years by using solar energy, biodiversity, and nutrient cycling.

• Concept 1-1B Our lives and economies depend on energy from the sun and on natural resources and natural services (natural capital) provided by the earth.

Sustainability Has Certain Key Components

• Natural capital: supported by solar capital• Natural resources: useful materials and energy in nature• Natural services: important nature processes such as renewal of

air, water, and soil

• Humans degrade and rely on natural capital

• Scientific solutions needed for environmental sustainability

Ecosystem Services

Natural Capital and Natural Resources are now “Ecosystem Services”

Old way of thinking: Ecosystem Goods• Raw materials provided

by nature• Essential inputs into all

economic production• We can use them up as

fast as we like• If I use it, you can't• Competition for use

• Market goods• Ecosystem structure,

building blocks of ecosystems

Ecosystem Services

• Structure generates function• Ecosystem functions of value

to humans known as ecosystem services

• Includes life support and human well-being functions

Desalinization

Factors that determine the costs for desalination include capacity and type of facility, location, feed water, labor, energy, financing, and concentrate disposal. Desalination stills now control pressure, temperature and brine concentrations to optimize efficiency.

Panarchy

Panarchy is a conceptual term first coined by the Belgian philosopher, economist, and botanist Paul Emile de Puydt in 1860, referring to a specific form of governance (-Archie) that would encompass (pan-) all others.

Panarchy

Panarchy is a conceptual term first coined by the Belgian philosopher, economist, and botanist Paul Emile de Puydt in 1860, referring to a specific form of governance (-Archie) that would encompass (pan-) all others.

Panarchy: Understanding Transformations in Systems of Humans and Nature also simultaneously coined the term, saying: The term [panarchy] was coined as an antithesis to the word hierarchy (literally, sacred rules). Our view is that panarchy is a framework of nature's rules, hinted at by the name of the Greek god of nature, Pan. (CS “Buzz” Holling)

1. Provisioning Services

• Production of food, fuel, fiber (regeneration of structure)

• Food (fish)• Food (crops)• Materials for clothes

(fur, leather)• Building materials

(Tiber)

2. Regulatory Services

• Water regulation• Disturbance reg• Erosion control• Soil creation • Pollination• Climate regulation• Nutrient cycling• Biological control• Waste absorption• etc.

3. Cultural Services

• Recreation, tourism• Forests: jobs for

2,393 Vermont • Annual payrolls of

$33 million annually• Scenery• Cultural attachments• Surfing

Supporting Services (kind of?)

• Habitat• Refugia• Without

biodiversity, there are no other services

When making decisions about ecosystem services, there are trade-offs

There is still a lot to figure out about ecosystem services

• What services are most managed?• How are they managed? By whom?• Where are they managed? Who benefits?• Are there environmental polices that specifically deal with

ecosystem services?

Surveyed 250 environmental managers on the local, state, and federal levels (both gov’t and NGOs)

Ecosystem services are the benefits people obtain from ecosystems

Management is researching, monitoring, making decisions, and/or providing outreach or education

Ecosystem Services in Literature

If Eco Services are so important, what services are we managing?

If Eco Services are so important, why are we managing them?

At what scale are we

managing them and who

benefits?

When making decisions about ecosystem services, there are trade-offs

How do we not imbalance these cycles and move toward more sustainable

outcomes?

Such as simple thing….but pretty important

• As a way to decrease the rate of natural capital degradation…

Increased consumption has had a significant impact on the environment which was driven by a number of factors…

Post WWII 2 things significantly impacted resource consumption

First, there were more people (and more people consume more than fewer people).

After World War II, consumer spending no longer meant just satisfying an indulgent material desire. In fact, the American consumer was praised as a patriotic citizen in the 1950s, contributing to the ultimate success of the American way of life. "The good purchaser devoted to 'more, newer and better' was the good citizen," historian Lizabeth Cohen explained, "since economic recovery after a decade and a half of depression and war depended on a dynamic mass consumption economy."

Reuse

Fig. 1-7, p. 11

Recycle

Fig. 1-8, p. 12

Scientists estimate that we could recycle and reuse 80–90% of the resources that we now use and thus come closer to mimicking the way nature recycles essentially everything. Recycling is important but it involves dealing with wastes we have produced. Ideally, we should focus more on using less, reusing items, and reducing our unnecessary waste of resources.
