Resources (water) challenge
- 1. Entry Task • What resources are abundant in Africa? • What resources are scare in Africa? • How have both types of resources affected African people?
- 2. Objective: • The students will be able to analyze the affect of abundant and scare resources on African society and livelihood.

- 6. • Drinking water: our bodies need to stay hydrated in order to function properly • For cleanliness: Poor sanitation can lead to disease • To grow food: Many people depend on farming for survival
- 8. Remember, only 3% of the water on earth is freshwater… …we cannot use saltwater for drinking or watering crops
- 10. Where is all the freshwater? Glaciers and Icecaps Groundwater Rivers and Lakes Atmosphere
- 11. • There is very little freshwater to go around • High Demand + Low Supply = High Value • Water is incredibly valuable in areas such as Northern & Eastern Africa
- 12. So here’s the dilemma… You need fresh water There are limited places to get fresh water How do you get it? First let’s take a look at some physical features
- 13. Physical Features of North & Eastern Africa
- 14. Mountains! • In the Western part of North Africa you can find the Atlas Mountains
- 15. Rivers • Many rivers were the site of early civilizations • Egyptians depended on the yearly Nile flooding for survival
- 16. So back to our original question Given the landscape of North & Eastern Africa how do you think people get the water they need?
- 17. Aquifers • One solution is to pump water out of aquifers – An aquifer is water that is stored in underground layers • Problems with aquifers – Not all locations have great sources of groundwater that are easy to access – Groundwater can be contaminated by bad soil – If water is removed faster than nature replaces it, the aquifers run dry
- 18. Building Dams • Building a dam on a major river can allow water to collect, and be redirected to another location • Problems with building dams – It takes away water that would flow to other countries – Can cause conflict among those countries
- 19. Rationing • Making water resources available in limited amounts
- 20. Desalinization • Treating saltwater to remove salts and minerals, makes it drinkable • Very expensive process, so poor countries do not have this option, and still have shortages • Oil rich countries have developed plants, making Southwest Asia the leader in the process
- 21. So what is the right answer? • There are pros and cons to each option • Is there a right answer? Is there a way to make everyone happy, and get everyone the water they need to survive? • What do you think is the best solution to this challenge?
