14.1 How We Use Land
14.2 Urban Land Use
14.3 Land Management & Conservation
- forest land
- wetlands/mountains/deserts, other
- urban land
●Urban: land covered mainly with buildings and roads
●Rural: contains relatively few people & large open spaces
Write in your notes an example of an urban area and a rural area and underline them both.
● Ecosystem services: the resources that are produced by natural & artificial ecosystems
- purification of air & water
- preservation of soil & renewal of soil fertility
- regulation of climate
- aethetic beauty
●Urbanization: Movement from rural areas to cities
- Usually roads and transportation have been built to handle growth, so traffic flows smoothly.
- These areas are usually more pleasant places to live because “green space” has been planned.
● There may be trouble when urban growth is rapid.
Includes: roads, libraries, hospitals, water mains, schools, sewers, power lines, bridges, fire + police stations
● Urban sprawl
● Heat island
The name for the increased temperature in the
In some areas, increased rainfall is a side effect
of the heat island.
Write in your notes why a heat island may result in increased rainfall. Remember what we learned earlier this year about warm air.
● Land-use planning
- what/where decisions
● Geographic information system (GIS)
- powerful because you can overlay information
Open spaces include parks, public gardens, and bicycle and hiking trails.
Some of the benefits of open spaces include:
- Plants absorb CO2/produce O2 and filter out pollutants from the air.
- Urbanites can exercise and relax.
Main categories of rural land:
national and state parks
- too many plants are eaten
- changes in plant communities
- or all plants are eaten
- nothing to keep soil from
People use enormous amounts of wood. The worldwide average is 1,800 cm3 of wood used per person each day. In the United States, each person uses 3.5 times this amount.
- protected from exploitation
2. Drinking water
4. Combat climate change
5. Recreational pursuits
There is a constant battle in our world between our conservation efforts and the growing population.
Litter and traffic jams that have plagued our cities, now threaten many of our national parks.
