How We Use Land

●Land cover - rangeland- forest land- cropland- parks/preserves- wetlands/mountains/deserts, other- urban land

 

Compare

●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.

The Urban-Rural Connection

● Ecosystem services: the resources that are produced by natural & artificial ecosystems

examples:

- purification of air & water

- preservation of soil & renewal of soil fertility

- regulation of climate

- aethetic beauty

Section 14.2

Urban Land Use

●Urbanization: Movement from rural areas to cities

Slow growth: - 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.

Urbanization, cont.

● There may be trouble when urban growth is rapid.

● Infrastructure

Includes: roads, libraries, hospitals, water mains, schools, sewers, power lines, bridges, fire + police stations

Urbanization

Urban crisis

Urban sprawl in China

● Urban sprawl

Other Impacts of Urbanization

● Heat island The name for the increased temperature in the city. 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.

Urban Planning

● Land-use planning

- what/where decisions

● Geographic information system (GIS)

- powerful because you can overlay information

Advantages of open spaces

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.

Section 14.3

Land Management & Conservation

Main categories of rural land:

farmland

rangeland

forest land

national and state parks

wilderness

Farmland

Rangeland

Forest land

National Parks

State Parks

Wilderness

Rangelands

● Overgrazing- too many plants are eaten

- changes in plant communities- or all plants are eaten

- nothing to keep soil from eroding/blowing away

Forest lands

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.

● Clear-cutting

● Deforestation

● Reforestation

Wilderness

● Wilderness

- protected from exploitation

● Exploitation: use or utilization, especially for profit: the

exploitation of newly discovered oil fields. 2. selfish utilization: He got ahead through

the exploitation of his friends.

Benefits of protected areas

1. Biodiversity2. Drinking water3. Economics4. Combat climate change5. Recreational pursuits

Threats to protected areas

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.
