Southern Mesopotamia was NOT an easy place to live!

• A lot of sun = VERY HOT• Very little rain = not enough water• Rivers would flood• Soil was hard and dry• Few trees• Stones were scarce (very few)• Few natural barriers

A Difficult Environment

Mesopotamians were farmersFarms need water

4 Key Problems:1. Food shortages in the hills2. Uncontrolled water supply on

the plains3. Difficulties building and

maintaining irrigation systems to serve several villages at once

4. Attacks by neighboring communities

Q: What might neighbors fight over?

Food ShortagesBy 5000 BCE there is not enough land in the foothills to grow enough food for everyone

Q: Why did people move to the plains?

Climate:Foothills: mild weather, plentiful rain, timber for building

Plains: dry, little rain, no trees or stones for building, rivers that flood

The plains were called Sumer and the people who lived there were called Sumerians

Uncontrolled Water Supply in the River Valley

• Spring: rain and melted snow from the mountains flood the Tigris and Euphrates Rivers

• Rest of the year: sunbaked soil, dry, hard as stone

• Either too much water or not enough

• Sumerians built levees & dams
