Land Use Quiz

Ecological Footprint; what happens when exceeded?

Amount of biologically productive land and water needed to supply ppl with resources and to recycle waste/pollution.

• Measure of area (hectares); 100,00 m²

• biocapcity exceeded = ecological deficit

How much biologically productive space is available?

11.3 B hectares available - including cropland, forests, and fisheries but NOT deserts, glaciers, or open ocean

• 1.4 hectares per person ; decreases with pop. grow

Main reason for rise in footprint; main out of that?

Fossil fuels; oil

Footprint of developing vs. developed Countries

• Proportional avg. income to footprint; developing countries lower:

  • Food: usually developed = more meat → 2x energy needed prod., and intensive farming

  • Energy: developed more fossil fuel burning and CO2 emission (cars, factories), needs more CO2 fixation

  • Biome: amount of CO2 fixation on climate/veg

Name the 6 catagories of public land

National parks, managed resource protected areas, habitat/species management areas, strict nature reserves/wilderness areas, protected land/seascapes, national monuments

National Parks

• Managed for sci/ed/recreation

• 2.7% area

• Little/no resources used

  • Pros: conservaton, tourism; cons: displace indigenous ppl

Managed Resource Protected Areas

• Sustained use bio/mineral/recreation resources

• US Nat. Forests - Lincoln Nat. Forest

Habitat/species management areas

Managed to maintain biological communities (fire prevent, predator control); Lido Beach Wildlife Management Area NY

strict nature reserves and wilderness areas

protection of species/ecosystems; minimal human impact; wolong nature reserve, CH

Protected landscapes and seascapes

Nondestructive use nat. resources, op tourism/recreation (orchards, villages, beaches)

National Monuments

Unique sites culutral/natural interest

Resource conservation ethic

People should max resource use based on common good; policy makers shoud consider resource/monetary value nature

Multiple-Use Land

Created by conflicting interests; used to designate lands used for recreation, grazing, timber, minerals, etc.
