Factors of Settlement
• What factors influence where people live within a certain area?
• Generate a list of ideas on the board or using an overhead projector (data projector).
• Discuss the answers that are generated by students.
• Now, let’s look at the factors.

Factors of Settlement• Physical Factors - most settlements cluster near
bodies of water such as rivers and gulfs. People also settle in areas that have access to fresh water. Low-lying areas near fertile soil attracts settlement. Temperate and mild climate regions are also regions of large settlement.
• Human Factors - people settle in areas where they have access to natural resources, economic activities, and access transportation routes.

How do geographers study human settlement?
• A number of tools are available for geographers to study settlement patterns. These include:
• GIS• Maps (atlas)• Government data (charts, graphs, reports)• Satellite imagery

So where were the first settlements located in North Africa
and Southwest Asia?
• Fertile Crescent (Tigris and Euphrates River Valley) (Mesopotamia)
• Nile River Valley

Mesopotamia
• The earliest cities have been uncovered in the Tigris and Euphrates River valleys. About 3500 B.C. civilizations began here due to the rich soil created by the rivers.
• Mesopotamia is the land that is located between the two rivers.

Nile River Valley• The annual flooding of the river brought
nutrients to the soil and allowed farmers to grow crops in abundance.
• Farmers were able to predict the time of the floods and farming became more reliable.
• People relied less on nomadic ways of life.
• Farmers learned to retain water for use later in the year by developing irrigation and building reservoirs.

Persian Gulf• The Persian Gulf is located between Iran and the Arabian
Peninsula. It is an extension of the Indian Ocean.• The discovery of oil transformed the region from one of
desolation to one of commercial wealth as the global demand for oil expanded rapidly.

Sahara• The largest desert in the world. • It stretches from the Atlantic Ocean to the Red
Sea.• Temperatures can rise to over 130 degrees.• The desert consists of sand, mountains, gravel,
and rock formations.• Underground water supplies—aquifers—can
come to the surface. They can create an oasis.• In an oasis, wildlife and vegetation can survive.

Sahel
• Sahel means shore of the desert.• The Sahel is a narrow band of dry grassland that runs east
to west along the edge of the Sahara. It receives very little rainfall.
• People use the Sahel for farming and herding.• The Sahara has spread into the Sahel leading to
desertification.©2012, TESCCC
Population Distribution
• The majority of the population in this realm lives not in the dry arid regions but around water sources:
• The Nile• Mediterranean Sea• Euphrates and Tigris Basin• Lower mountain slopes of Iran, south of the
Caspian Sea

Water- A Renewable or Finite Resource?
• Water is critical for life, food production, and industrial processes.
• 9 of the 14 Southwest Asian states face water shortage conditions, the most concentrated region of water scarcity in the world.
• The North African states all have rates of natural increase above 2.0%, increasing the stress on water sources.
