www.seinan-gu.ac.jp/djohnson/natural/quakes.html - The Asia Pacific region, home to 53 of the
world's population and 20 of its land area,
experiences a disproportionate share of loss of
life and impact to socio-economic processes.
According to a recent United Nations' report,
nearly 70 of all lives lost due to natural
disasters occur within the Asia Pacific region
(U.N. Living with Risk, 2002). - Human Environment

249.2 Regional Resources
- African Sahel
- Contains Ethiopia, Eritrea, Djibouti, and
Somalia - Areas affected are Senegal, Mauritania, Mali,
Burkina Faso, Niger, - Nigeria, Chad, Sudan, and the "Horn."
- The climate is arid and unstable
- Hard to operate agriculture with very little
precipitation - Sparse savannah vegetation of grasses and
shrubs - 4 8 inches of rainfall per year (between June
and September) - A majority of the people are involved in
nomadic herding - Large number of livestock have overgrazed
causing excessive - desertification
- 1970's - drought that killed 300,000 people and
five million livestock - Rapidly growing populations with very high
rates of natural increase
259.2 Regional Resources
- African Sahel
- Grassland area south of the Sahara Desert
- Forest and woodland areas are declining by an
estimated 1 per year, while population grows at
2.8 per year (Sahel Regional Program/USAID,
1997). There is a growing lag between food
production and food needs, and evidence of
increasing environmental degradation - Almost 8 million people are currently threatened
by severe food shortages in the Western Sahel
region of Africaincluding Niger, Mali,
Mauritania and Burkina Faso. The famine, brought
on by two years of low rainfalls and drought in
the region, coupled with the worst locust
infestation in 20 years, has led to widespread
malnutrition.
269.2 Regional Resources
- Europe
- Dependence on fossil fuels from Persian Gulf
- Gasoline production is declining in Britain,
which became a net gas importer in 2004. The same
will be true for oil before the decade is out. By
2020, Britain will be relying on Russian and
Algerian gas for half of its electricity supply. - Spain is the most energy dependent in Europe. 80
percent of its energy needs are imported, with 99
percent of its oil and gas being imported. The
government plans to end use of nuclear power
(one-fifth of its electricity). - Politically volatile sources
- Iraq, Saudi Arabia, Iran
- Consumptive society
279.2 Regional Resources
- Russia
- Vast natural resource potential
- Petroleum
- Forests
- Minerals
- Poor infrastructure
- Roadless areas with large amount of resources
- Climate, terrain, and distance hinder
exploitation of natural resources - Fledgling Democracy with a command economy
- Government controlled natural resource companies
- Gazprom takeover

299.2 Regional Resources
- While the United States consumes roughly 19
million barrels of oil a day, mostly to power its
200 million automobiles, it produces only about 8
million barrels (or 42 percent) of that total
domestically. The other 58 percent -- some 11
million barrels a day -- of our oil has to be
imported from other countries.
309.3 Role of Technology
- Humans have always developed and used technology
to modify the physical environment in order to
settle areas in different world regions. - Evaluate the impact of these technologies on the
physical and human environments affected. Human
Environment Interactions, Spatial Interaction,
Change Over Time, Physical Systems
319.3 Role of Technology
- Human environment interaction
- Modification of physical systems to suit human
needs - Dams, levees, irrigation for example
329.3 Role of Technology
- Technological Efforts
- Netherlands (dams to claim land for development
and agriculture) - USA (New Orleans levees and dams for urban
development and growth) - China (Three Gorges Dam Displace large
population, but offer modernization) - Persian Gulf (Qatar, UAE Develop desert into
agricultural and urban centers)
339.3 Role of Technology
- Three Gorges Dam Project, China
- Located along the Yangtze River (3rd longest
river in the world) - Proposed width of 1.5 miles, 600 feet high, 400
miles long - Hydropower equivalent to 18 nuclear plants
- Offers greater access to interior regions
agricultural and - manufactured products.
- Future source of energy in response to growing
- consumption of population.
- Dam will flood more than 100 towns
- 1.2 million people will be resettled
- More fertile soils will be flooded and people
moved to less fertile - areas
- Approximately 1,300 archaeological and
historical sites gone - May provide up to 1/9 of Chinas electrical
production - Reduce extremely high use of coal in China
- Expected completion in 2009

- Creation of islands for more space in response to
demand for residential areas, as well as
increased tourism (resorts). - Use of technology to shape urban landscape

- Intensive irrigation projects for agriculture
- The country has no rivers or lakes, and besides
the rainfall received, the primary source of
fresh water is the ground water
