Global warming is causing melting icebergs, which leads to less drinking water and an increase in salt water levels. This document discusses two solutions to address these issues: desalination plants that remove salt from water through distillation or thin membrane filtering, and collecting rainwater in tanks for irrigation since fields use 70% of water consumption. While desalination provides drinking water, it is an expensive process requiring a lot of electricity. The conclusion is that if global warming continues, the best approach is to conserve drinking water and use desalinated or rainwater for irrigation to sustain agriculture.

1. What are the effects of the global warming on water management?

3. There are lots of consequences.

4. We will explain to you one of them.

5. Consequences of melting of iceberg

6. The consequences are : - Less drinking water - Increase in the salt water surface - Less icebergs

7. There are a lot of solution but we will base ourselves more particularly on the transformation of salt water into drinking water and the collection of water.

9. These factories used two methods :

10. The vacuum distillation, we heat the water until it boils and evaporates, which leaves the salts and minerals under.

12. Vd But the drinking water from these factories are often use to irrigate fields. And the desalinazation is very expensive because it needs a lot of electricity. But the salt can be sold.

13. Second solution We can also collect the rain in tank which we can use to irrigate field. (Fields use 70% of water consomation) We can't drink it because there aren't minerals .

14. Conclusion The only solution if we don't stop the global warming is to save drinking water and use rain and desalinated water to irrigate fields. Save me, stop the global warming !
