Predicting Drought Events
|
Objective - To complete a short study on the likely success of drought prediction and where this has been implemented.
We know that drought have medium to long term speeds of onset (known as a creeping phenomonen) and are not immediate hazards like earthquakes. However, with advances in meteorology, can we predict this onset and warn vulnerable populations? Task 1 - Complete all tasks set out in the worksheet above right. You will need the resources on this page to help you. Read this article from the National Drought Mitigation Centre. Outline the issues in predicting drought and any potential successes. ENSO = El Niño-Southern Oscillation Watch the YouTube video above about drought prediction in African countries and create a short case study using the content. Cover the social and economic effects as well as methods being used to reduce the problems. |

Drought Frequency
|
Objective: To relate global warming issues with frequency of drought events in Africa.
The tasks for this section will be completed on the same worksheet for the tasks above on frequency. You will need the resources below to help you. Read this article from Science Daily. a. Think about the potential relationship in the frequency of droughts in Africa and global temperature rises. b. Think about how many people are likely to suffer food shortages in the Horn Of Africa as a result of this hazard. c. What is the relationship between food shortage and drought? |
