5Urbanization
- Urban populations are growing and rural
populations are shrinking, especially in the
developing world.
6Urbanization
- Chicago grew faster than almost any other city in
the late 19th and early 20th centuries, then
declined slightly as residents moved to its
suburbs.

10The Midwest Foresight and planning, and now
little new protection, more reshuffling of
management
Established in early 20th century
11- Two primary issues with land use
- Providing livable spaces in and around our urban
environments - Protecting valuable natural resources, natural
legacies and functioning ecosystems
12Urbanization
See also Cities in the Wilderness, Bruce Babbitt
- Today cities like Phoenix and Las Vegas are
growing as fast as Chicago once did. They are
spreading across the landscape, as shown by these
satellite photos of Las Vegas

14The Changing urban, suburban and exurban
environment
These people need parks
But, as we build these, people tend to build
their own parks in the form of large yards.
15Growth vs. sprawl
- Economists, politicians, and city boosters
traditionally encouraged growth, assuming it was
economically good. - Growth has become synonymous with sprawl.
Americans rethinking the benefits of growth. - (Note the positive connotation of growth and
the negative connotation of sprawl.)
1619th / 20th century legacy
- The Great Society
- Liveable spaces with parks and open space
- Open space generally for the public good
- East Bay Parks, Presidio, Golden Gate Park, Mt.
Tam,etc.
17Reduce tax the burden of providing public goods
- Privatizing open space protection.
- Trust for Public Land
- Shift in emphasis
- Natural Resource Protection
- Ecosystem Services
- Buffers between urban and rural landscape
- Protecting critical land uses agriculture

19Deforestation
- Timber harvesting propelled the growth of the
young United States. - Forests were leveled first in the East, then
one by one moving westward.
Figure 16.8
20Deforestation
- Over 3 centuries, Americans denuded most of their
forests (green).Even in the green areas
mapped above, very few large virgin trees
remained nearly all forest is second growth.

21Measuring forest cover
- A 2001 international study used GIS with
satellite data to put together an accurate
inventory and map of the worlds forest cover. - 20 of Earths surface remains covered by closed
forest. - 88 of this is sparsely inhabited by people.
- 80 is concentrated in just 15 nations.
From The Science behind the Stories
22Forests and deforestation
- Demand for wood products, and for open land for
agriculture, has led to deforestation, the
clearing and loss of forests, throughout the
world.
- Africa and Latin America are losing their forests
most quickly. - Forests are starting to grow back in North
America and Europe after centuries of
deforestation.
23Growth and removal of timber
USA
- Forests are growing back faster than they are
being cut on all types of land except timber
company land.
24The eastern seaboard declining agriculture,
increasing forest acreage and increasing urban
footprint
25Federal lands
- U.S. federal agencies own a large amount of land
in the western U.S., allowing resource extraction
on most of it.
National forests green
26Logging Private and public
- Logging has risen on private land, and has fallen
on public land since 1986.
Figure 16.13
27Methods of logging
28Design of protected areas
- How parks and reserves are designed has
consequences. - Recall how habitat is fragmented by development
Forest fragmentation at Mt. Hood N.F., Oregon,
and in Cadiz Township, Wisconsin, 18311950.
29Our presidents plan for handling global warming
30And, Californias
31Agricultural land use lots more about this in 2
weeks
- Agriculture now covers more of Earths surface
than forests. - 38 of planets land surface agriculture
- 26 pasture/rangeland
- 12 cropland
- Intensive monocultures completely displace
natural ecosystems and have a heavy impact on the
land.
32Agriculture and wetlands
- Most of North Americas wetlands have been
drained, filled, and converted for agricultural
use. - Monoculture farmland encroaches on prairie
pothole wetlands in North Dakota.
33Rivers
34Nutrient and sediment plume from the mouth of the
Mississippi
35Rangelands
- Livestock grazing
- Done badly, it can ruin soils, cause erosion and
desertification. - Done responsibly, it can sustain grasslands,
allow wildlife use.
36Rangelands
- Most ranching takes place on federal land managed
by the Bureau of Land Management (BLM)purple in
map. - Grazing fees are extremely cheap.
Figure 16.10
37Estuaries S.F. Bay is a prime example of how
estuarine systems get either silted in or
deliberately filled when associated with
agriculture and human development. This 1960
picture depicting SF Bay in 2020 in the Oakland
Tribune helped stimulate Catherine Kerr and the
founders of Save SF Bay Assoc.
38Endangered Ecosystems
California
- 99 loss of native grassland (from 9 million to
89,100 ha Kreissman 1991). - 94.2 loss of native grassland in San Diego
County (Oberbauer 1990). - 80 loss of tidal marshes in the San Francisco
Bay (Lewis 1992). - 99.9 loss of needlegrass steppe (Barbour et al.
1991). - 90 loss of northern coastal bunchgrass (Barbour
et al. 1991). - 99.9 loss of Central Valley riparian oak forest
(Martin 1986). - 100 loss of coastal strand in San Diego county
(Oberbauer 1990). - 70-90 of presettlement southern California
coastal sage scrub destroyed (Westman 1981
Atwood 1990 Oberbauer 1990 O'Leary 1990 U.S.
Fish and Wildlife Service 1992). - 94 loss of inland wetlands (Barbour et al.
1991). - .. (41 examples in all for CA)
- 8,653 increase in non-native annual grassland
(Barbour et al. 1991).

43Why create parks, reserves, and wildlands?
- Monumentalism
- 19th-century landscape painters raised great
interest in the American Wests sceneryand its
new national parks. - Here, Bridalveil Falls in Yosemite by Albert
Bierstadt
44U.S. national parks
- 1872 Yellowstone National Park becomes the
worlds first national park - a public park or pleasuring-ground for the
benefit and enjoyment of the people - Today, the U.S. national park system includes 388
sites and receives 277 million visits each year. - It is managed by the National Park Service.
45U.S. national wildlife refuges
- 1903 President Theodore Roosevelt begins system
of national wildlife refuges - Today, 541 sites are managed by the Fish and
Wildlife Service - from preservation to active manipulation of
habitats and populations - Hunting, fishing, and other recreation and
allowed policies vary from refuge to refuge.
46Wilderness areas
- 1964 Congress passes Wilderness Act
- Wilderness areas can be designated within
existing federal lands. - They are open to public recreation, but not
exploitative development. - Criteria Large, undisturbed, roadless,
representative
47Wilderness areas
- To assure that an increasing populationdoes not
occupy and modify all areas leaving no lands
designated for preservation and protection in
their natural condition. U.S. Congress
48Last year
49www.wilderness.net
50California
51British Columbia set aside 865,000 acres of
protected land for caribou
52Opposition to land set-asides
- Restriction of activities in wilderness areas has
generated opposition from private landowners that
would like access.. - State governments of Western states would like to
have control over more land within their borders. - Nevada 80 of land federally owned
- ID, OR, UT 50 federally owned
53- California is under the strain of competition for
land use between - Public resources
- Agriculture
- Developed private land
Conflicts are inevitable
54Public Lands
- Is it any wonder that Senate and House Committees
on Resources are usually chaired by reps. from
western states?
55Opposition to land set-asides
- Wise use movement loose confederation of
individuals who live off the land and industries
that extract resources, who oppose advances of
environmental advocacy, and - Want to protect private property rights
- Oppose government regulation
- Want federal lands transferred to state, local,
private hands - Want more motorized vehicle recreation on public
lands, ability to build roads
56Land trusts
- Besides federal and state governments, private
nonprofit groups called land trusts also set
aside land for protection from development. - Local or regional organizations
- 900 in U.S. have helped preserve 1.1 million ha
(2.7 million acres)

60International parks and reserves
- Protected areas have been growing fast in many
countries. - The world now has 38,500 protected areas,
covering 9.6 of the planets land surface. - But many of these are paper parksprotected on
paper, but subject to illegal exploitation
because of lack of funding for enforcement.
61International parks and reserves
- Biosphere reserves that straddle international
boundaries consist of three zones, combining
preservation with sustainable development.

62Privately funded programsDebt for Nature Swaps
- Private conservation foundation buys off national
debt in exchange for country setting aside
conservation lands - Bolivia - Conservation International (CI)
- CI used 100,000 to buy 650,000 of debt that
Bolivia was defaulting. - In exchange, Bolivia set aside 3.7 million acres
- That is 37 / acre for tropical forest!
- Problems remain in enforcement of protection
- The Nature Conservancy, World Wildlife Fund, CI
- 19 swaps, 17 million to retire 99 mil of debt

66SustainableDevelopment Programs
- Linking preserving people and biological
resources (e.g., Rural Development and
Conservation projects sponsored by US AID) - Combination of resources applied to conservation
of traditional rural cultures and biological
resources - Theory is that they lived in combination with
resources through the past, why not into the
future? - Usually suffers from increased population and
standard of living (pressure to increase cash
income) - Not always clear whether success is measured by
the conservation of culture or biota - Many successful programs are driving species
extinct

73This lecture will help you understand
- Land use decisions
- Urbanization and urban sprawl
- Forestry and forest management
- Agricultural land use
- Parks and reserves
- Planning for livable cities
74Conclusions Challenges
- Urban populations continue to grow, making it
necessary to improve conditions in cities. - Urban sprawl eats up undeveloped land.
- Balancing timber production with preservation of
forest ecosystems, and managing for fire, poses
challenges. - Agriculture comprises huge amounts of land, and
often degrades it. - There is debate over how much land should be
protected. - There is debate over how best to design reserves.
75Conclusions Solutions
- Effective city planning and better public
transportation can make cities more livable and
can mitigate the impacts of urban sprawl. - The Forest Service has begun moving toward a
better balance of management for timber,
ecosystems, and fire. - Agricultural practices can be further improved to
lessen the impacts upon soil and biodiversity. - Democratic debate over land protection policy is
healthy. - Through science, conservation biologists are
progressing in determining how best to design
reserves.
