  1. Mr. P. Lui How to stoP DESERTIFICATION?

  2. OVERGRAZING DEFORESTATION OVERPOPULATION OVER-CULTIVATION

  3. Drought Forces Nomads to Settle Down 2 July 2007 • For centuries, the Tuareg people have lived as nomads, herding their animals from field to field just south of the Sahara Desert in Mali, near Timbuktu.

  4. NO FOOD? • But this way of life has become IMPOSSIBLE due to a change in the climate. • Over the past 40 years, prolonged drought has forced the Tuareg to give up their wandering way of life. • To survive they have had to start settling in villages and cultivating land to secure a food supply which is less affected by drought.

  5. Worries of tuareg • Tea ceremonies are one of the traditions that the Tuareg nomads have held onto. While some Western influences are welcome, some villagers worry their traditions will slowly erode.

  6. Changing lifestyle of nomads • Some nomads near Egypt worked for the tourists, keeping their camels and taking pictures with tourists.

  7. What if some nomads insist on herding? • The government can encourage nomadic herders to rear LESS cattle and grow FAST-growing pastures.

  8. How to solve the drought problem? • The government can build IRRIGATION canals and dig WELLS to provide irrigation water.

  9. Aswan high dam in egypt

  10. Is it a long-term measure? • The government can teach people to grow crops of higher YIELD. Irrigation scheme in Israel

  11. How to stop over-cutting? • AFFORESTATION can protect the land against soil EROSION. • Villagers plant sacsaoul trees in Minqin County, northwest China's Gansu Province,Mar. 11, 2009. • Minqin County, located in between the Tengger Desert and the BadainJaran Desert, is surrounded on three sides by the deserts. • The county fenced about 8667 hectares of sand land and artificially afforested other 4500 hectares in 2008. • The county planned to artificially reafforest some 5400 hectares of sand land this year.

  12. Affoestation in gansu • Villagers water sacsaoul trees in Minqin County, northwest China's Gansu Province, Mar. 11, 2009.

  13. How to solve energy problem in rural areas? • Develop RENEWABLE energy, such as WIND and SOLAR power. • People do not have to cut trees and grass for FIREWOOD.

  14. A man rides his motorcycle through the desert as wind turbines spin at the Dabancheng wind farm site. • This wind power facility is China's largest wind farm. China, home to 16 of the worlds 20 most polluted cities, is beginning an aggressive initiative to pursue renewable energy. • Its held that China has the most wind power potential of any country in the world, taking into account its inland and offshore sites. • By 2020 China is expecting to produce 10% of its energy from renewables: namely wind, solar energy, hydroelectric dams and biowastes.

  15. Birth control and family planning • Women walking by an advertisement for Prudence condoms in Abidjan, Ivory Coast. Condoms are an effective way to block sexually transmitted diseases, including the HIV-AIDS virus.

  16. Birth control and family planning

  17. Do these measures work?

  18. Do these measures work? • Lack of CAPITAL and TECHNOLOGY • Lack of GOVERNMENT support • Natural CLIMATIC change • Farmes are poorly EDUCATED  unwilling to rear FEWER animals, grow FEWER crops and practise BIRTH control. • Population PRESSURE is great as population grows rapidly.

  19. solutions effectiveness • Less cattle + fast-growing pastures • Irrigation canals +wells  higher yield • Afforestation  soil erosion ↓ • Renewable energy = wind + solar power = firewood ↓ • Birth control + family planning • Capital • Technology • Government support • Education level • Behavioural factor • Natural climate change SUMMARY
