2. Drought
Creeping hazard: slow onset, long-duration, chronic, relatively large areal extent.
Worldwide, not tied to certain geography, but more frequent in “semi-arid” climates.

7. Iran is located in the southwest of Asia between 44º 02´ and 63º 20´ eastern longitude and 25º 03´ to 39º 46´northern latitude. The country covers an area of about million square km.
Area: million km2
Population: 75 million
No of provinces: 30
Average Rainfall: 250 mm
Neighboring Countries:
Afghanistan, Pakistan,

8. Climate
Iran’s climate varies from region to region: • The winter temperatures in the mountainous areas of the north-west drop as low as -29˚C • The Khuzestan Plain has extremely hot humid summer with an average temperature of about 35˚C • Most of the interior plateau has a dry climate, but the winters are mild and pleasant • The average annual precipitation is 250 mm and the range (varies from 50 mm to more than 1600 mm )

12. Drought in Iran
Drought is one of the most serious natural disasters in the world and Iran, which has exerted great pressure on ecological sustainability and diversity, food and water supply, etc.
Drought frequency has increased in many parts of Iran, and more severe drought events has happened in the last 50 years.

15. Greenhouse Effect and Global warming

16. What about the solution?
Drought Accelerates Dust Storms!
Drought and Dust Storms Know No Country Borders !
So:
What about the solution?

17. Dust storms are natural events
Dust storms are natural events. However, scientists believe human activity is causing them to occur more frequently in certain regions, and their impact can be devastating.
Co-existing with dust storms can be summarized in three words: prevention, preparation and prediction.

Impact of Climate Change and Drought on Different Sectors
A National Master Plan
Maybe regional plan in the future!
Who knows?

19. Conclusion
With global warming and water demands increasing, drought and consequent dust storms will be the long-term challenges in the future from a global perspective.
Droughts and dust storms are the normal part of nature. Human beings cannot avoid them, but we can reduce the disaster risk by taking proactive measures, thus avoid or alleviate the disaster.
Remote sensing is a very useful tool to understand the origin, extent and frequency of dust storms for early warning and better understanding and management of the disaster especially for distant and less accessible regions.

20. Conclusion
Importance of Regional Collaboration and Framework in Drought and Dust storm Management
As the core content and key element of risk management, drought and consequent dust storms should get more and more concern from governments, researchers, communities, even public.
