1. WHAT IS NATURAL RESOURCE ECONOMICS & WHY IS IT IMPORTANT?

2

Key Terms

u Natural Resources– Specific attributes of the environment that are

valued or have proven useful to humans [or have the potential to do so]* --G. Johnston

– Aspects of nature that can be used by humans to satisfy human wants--Hite & Mulkey

– key to human use: technology, time, accessibility, appli-cation, perception; conflicts often related to culture

u Economics– the study of the production, processing,

distribution, consumption of goods/services in an exchange system

3

Key Terms (cont)

u Natural Resource Economics– application of economics to manage naturally

occurring resources for human needs/wants with efficiency as the primary goal

– efficiency may be defined in market or nonmarket terms, focused on the short or long run, relative to current or future generations, local or global in scope

– decision choices include maintaining the status quo, altering the status quo, or doing nothing with focus on relevant institutions

– evaluation always includes the costs & benefits of a decision & to whom those costs & benefits accrue

4

Key Terms (cont)

u Environmental Economics vs. Natural Resources Economics (Hackett)– Environmental Economics: economic basis for

pollution problems & policy alternatives– Natural Resources Economics: problems of

managing common-pool* natural resources, determining optimal rates of extraction, & understanding resource markets

– *common-pool natural resources: difficult to exclude access, but once extracted is no longer available to others (groundwater, rivers, fisheries, public forests)

u Scarcity, Opportunity cost, economic rationality

5

Why Study Natural Resource Economics?

u Natural Sciences lack commonly accepted decision process

u Economics may “assume” the problem awayu Irreversibilityu Market failureu Joint importance of economic and ecological systemsu Physical-Natural-Economic System Links

– Improves efficient functioning of system– Improves understanding about the world we live in

u Summary: Improved management of natural resources, whether for private, public or natural gain

Classification of Natural Resources

NATURAL RESOURCES

FLOW RESOURCES

FUND RESOURCES

NONSTORABLE RESOURCES

(ENVIRONMENTALRESOURCES)

STORABLE RESOURCES

RENEWABLE RESOURCES

NONRENEWABLE RESOURCES

NONRECYCLABLE RESOURCES

RECYCLABLE RESOURCES

Classification of Resources (continued)

1. Flow Resources (nondepletable)a. Nonstorable (sometimes called “environmental resources”)»Often indivisible»Inexhaustible (in human span of time)

»Time & management relevant only to consumption, not supply

8

Nonstorable Flow Resources

Sunshine

“Weather”

Ocean Waves

Ecosystems

Classification of Resources (cont)

1. Flow Resources (cont)b. Storable (by nature, as in living

matter; by humans with technology)» May be divisible» Time & management relevant to

both to consumption & supply » The services are what are

significant for humans

10

Storable Flow Resources

Solar

Wind

Wave Energy

Geothermal Energy

Hydrogen Energy WaterHydroPower

Classification (cont.)

2. Fund Resources (stock or depletable resources)a. Exhaustible & Renewable

»Regenerative within human use time frame

»Assumes use within minimum & maximum thresholds

12

Exhaustible & Renewable Fund Resources

Timber & Crops

Animals(human & nonhuman

Fish

GrazingLands

Soil & Water Quality

Forests & someUnique ecosystems

13

Classification (cont.)

2. Fund Resources (cont)b. Exhaustible & Nonrenewable

»Relatively fixed stocks/fund within human use time frame

(1) Nonrecyclable--Examples: fossil-fuel energy resources (oil, natural gas, coal, peat, many “renewable” resources when thresholds violated)

(2) Recyclable--Examples: some minerals (iron, aluminum, gold, silver)

14

Framing Natural Resource Issues

u Quantity & Quality of: Land, Water, Air, Energy

u Public vs. Private Management Questionu Trend of Magnitude of Problem:

– Persistent, Chronic, Cyclical, Declining, Growing?u Irreversibilityu Geographic scopeu Whose problem & who decides (ethics)?u Property rightsu Time (short vs. long run; current vs. future

generations)

15

Optimism vs. Concern for Environment & Natural Resources

u Concerns– Global warming & climate impacts– Over-population & biodiversity– Soil/water quality/Mineral/energy

cost/availability– Pollution/resource shortage impacts on social

& political institutions
