NATURAL CAPITAL
Environmental Systems and Societies

Explain the concept of resources in terms of natural income.
● Natural resources = raw materials from nature
● Natural capital = natural resources with a value to
humans
● Natural income = growth of natural capital
3.2.1
Explain the concept of resources in terms of natural income.3.2.1
● Natural income is the growth
or yield of natural capital:
○ agricultural harvest
○ growth of timber
○ increase in herd size
● Only exists as long as the
original resource remains in
place

● How does this image relate to natural capital?
● What about natural income?
Explain the concept of resources in terms of natural income.
Ecological goods may be
made into products
● metal ores
● minerals
● wood
● animal products
3.2.1
Explain the concept of resources in terms of natural income.3.2.1
Ecological services aren’t
monetized:
● O2 from photosynthesis
● carbon sequestration
from respiration
● water cycling and
filtration
● flood and erosion controlhttp://www.wsl.ch/fe/oekosystem/gebirgsoekosysteme/themen/vegetation_bodenstabilitaet/Soil_Klosters.jpg and http://faculty.washington.edu/ktorii/images/research/stomata_fig1.jpg
Define the terms renewable, replenishable and non‑renewable natural capital.3.2.2
http://www.worldresourcesforum.org/files/images/natural-resources-classification.gif
Define the terms renewable, replenishable and non‑renewable natural capital.3.2.2
Renewable natural capital is self-producing (living) and self-maintaining (ecosystems).● Needs solar energy
● can be sold/marketed (wood, ethanol, food)
● some give essential services when left alone ○ elephants (habitat maintenance - NO IVORY!)
○ forests (local temperature and water filtration)
Define the terms renewable, replenishable and non‑renewable natural capital.3.2.2
Replenishable natural capital is non-living but is also often dependent on the solar “engine” for renewal.● groundwater
● wind
● ozone layerhttps://www.acs.org/content/acs/en/education/resources/highschool/chemmatters/past-issues/archive-2012-2013/ozone-layer-our-global-sunscreen/_jcr_content/mainContent/columnsbootstrap/column0/textimage_0/image.img.jpg/1368218980203.jpg
Define the terms renewable, replenishable and non‑renewable natural capital.3.2.2
Non-renewable natural capital = any use implies
liquidating (depleting) part of the stock
● minerals
● fossil fuel
● metal ores
Finite supplies will eventually run out!

Explain the dynamic nature of the concept of a resource.
Dynamic = changing status of a resource over time and/or space due to...● Cultural, economic, and
technological shifts● “Environmental value
systems”● What about ethanol, oil, solar?

Discuss the view that the environment can have its own intrinsic value.
Intrinsic value is the “inward” value of nature regardless of its practical (economic) use to humans.● ethical, spiritual + philosophical
perspectives
● hard to quantify
● How to debate aesthetic value with an
economist?

Discuss the view that the environment can have its own intrinsic value.
Intrinsic value may include● sacred spaces
● beauty (beholder’s eye)
● biodiversity
● rate of depletion
● health benefits
● societal well being

Explain the concept of sustainability in terms of natural capital and natural income.
● Living on the ‘interest’ generated by natural capital.
● Using only the growth or increase in resources
● Wisely using and maintaining resources - goods
and/or services
● Not depleting natural capital
● Sustainable = may be continued indefinitely into the
future
3.2.5
Discuss the concept of sustainable development.
● Brundtland Report (1987): introduced the term “sustainable development”
● Meaning is debatable○ Economists: stable annual return on investment regardless of
the environmental impact.
○ Environmentalists: stable return without environmental degradation.
○ Environmental Value Systems…?
3.2.6
Discuss the concept of sustainable development.
● UN Conference on Environment and Development (UNCED)
● a.k.a. Rio Earth Summit (1992)○ Sustainable development○ Climate change + alternative energy sources○ Production of toxins○ Public transportation○ Water scarcity
3.2.6

● Largest gathering of governments and NGOs in history.
● Meant to build consensus.
● Successful?

● Agenda 21● Action plan for
sustainable development
● Non-binding, voluntary
● 4 focus sections

1. combatting poverty
2. Protecting the atmosphere,
forests, and biodiversity
3. Strengthening youth,
women, NGOs, local
authorities, and indigenous
peoples, and farmers.
4. Implementation strategies
Calculate and explain sustainable yield from given data.
● Sustainable yield = rate of increase in natural capital○ what can be used without depleting the original stock○ must be less than natural income○ calculated according to these formulae below:
