Drought This topic may be used in the following key ideas: 1. Different types of natural hazard have specific global distributions. 2. Natural processes are responsible for causing severe natural hazard events. 3. Natural hazards have a significant impact on people and their quality of life. 4. The level of economic development of places affected by natural hazard events influences the severity of the impact. 5. People continue to live and work in places that are prone to natural hazards. 6. Human activities can affect the impact of natural hazards. 7. A range of methods are used to attempt to reduce the impact of natural hazards. 8. Some methods are more sustainable than others. Glossary: drought arid desert Sahel desertification deforestation over-grazing Ethiopia, part of the Sahel 12-17 degrees north South of the Sahara Australia Moist air prevented from travelling north from Kenya El Nino (see Miller p149 Q1a) Population: 77m Crop failure 7 people in 8 are rural dwellers Livestock dies (starvation, thirst) Average daily temperature is 28-30 degrees Farmers give up and move to 77% of trees cut down(deforestation) cities Many new soil-depleting eucalyptus plantations Soil erosion 1998-2000 civil war Farmers borrow money and get Money spent on armed forces into debt Population increase Dust storms Poor farming techniques – growing crops in low Bush fires rainfall areas Water shortage Over-grazing of animals Increase in levels of toxicity in Soil erosion – by rain and wind water supplies Large scale migration of people High demand for fuel wood North-east Africa Poor harvests High death rate Poor health and increase in disease Relief camps Starvation – over 5m needing emergency food aid “Do they know its Christmas?” For Ethiopia, write an account, including details about: where, why and impacts. The why should be reasons.

Coping with drought Hitosa Water Supply Project Build dams and reservoirs Ethiopia Water transfer schemes Very expensive weekly Tree planting (re- water tanker afforestation) Water pipeline failed due to Micro dams disrepair Piles of stones to collect Water collected from condensation mountain springs Drought resistant crops 140Km of pipeline Drip irrigation 122 distribution points Cloud seeding Government designed, local desalinisation labour – a self-help scheme Maintained by local people 70000 have water Improved quality of life www.wateraid.org 1. Which coping strategies would be (a) suitable for Ethiopia; (b) suitable for Australia? 2. Describe the Hitosa Water Project, and explain how peoples’ quality of life would have improved.
