  1. REGIONAL SLIDES

  2. Asia and the Pacific • Ok Tedi Mine, Papua New Guinea • Weipa Bauxite, Australia • Huang He Delta, China • Isahaya Bay, Japan • Phnom Penh, Cambodia • Thon Buri, Thailand • Dead Sea, Jordan • Aral Sea, Kazakhstan • Lake Balkhash, Kazakhstan • Kara-Bogaz-Gol, Turkmenistan • Three Gorges Dam, China

  3. Asia and the Pacific • Lake Hamoun, Iran • Mesopotamia, Iraq • DMZ, Korea • Oudomxay, Laos • Papua, Indonesia • Sundarban, India/Bangladesh • Shatt al-Arab, Iraq/Iran • Al Isawiyah, Saudi Arabia • Wyperfeld National Park, Australia • Paektu San, North Korea

  4. Asia and the Pacific • Asia is home to 60% of the world’s population, with only 36% of the world’s freshwater resources; majority of the global population without access to improved sanitation lives in this region • Asia has reversed the rate of forest loss from loss of 1.3 million hectares per year in the 1990s, to a net gain of more than 600 000 hectares per year between 2000 and 2005, yet the region has the lowest amount per capita (0.2 hectares) of forest in the world • Agriculture is the mainstay of Asian economies; it constitutes a high portion of land usage in warm and humid areas of Asia;majority of Asia's poor people depend directly or indirectly on agriculture for their livelihoods UNESCO 2005; FAO 2005; CGIAR 2005

  5. Environmental Impact of Copper Mine Ok Tedi Mine, Papua New Guinea These images show environmental impact of the mine • 1990: Both the mine and township of Tabubil, are clearly visible • 2004: Raised river beds, forest damage and decline in biodiversity are some impacts

  6. Lowering of landscape in Weipa bauxite mine, Australia These images show environmental impact of the mine • 1973: Under current mining practices, vegetation is cleared and the topsoil is removed • 2002: Image show larger extent of cleared area

  7. Dramatic changes in Huang He Delta, China The delta changed dramatically between 1979 and 2000 • 1979: Huang He’s yellow color is the result of huge load of sediments • 2000: The image clearly shows the change in Delta

  8. Changes in Huang He Delta, China • From 1989 to 1995 the Yellow River delta grew in area • From 1995 to 2000 the Yellow River delta shrank in area

  9. Land reclamation changes along Isahaya Bay, Japan • 1993: Turning tidal lands into farmlands • 2001: The straight line of sea wall is visible • 2003: The area has been fully reclaimed from the sea

  10. Flooding in the Mekong River:Phnom Penh, Cambodia These images show the extent of flooding and extensive ditches and canals used for irrigation • 2000: Taken during the period of flooding • 2001: Taken after the flood waters had receded

  11. Replacement of mangroves by aquaculture in Thon Buri, Thailand • 1973-1978: Area is engulfed in a conflict between needs of people versus the welfare of the coastal areas • 2002: Shows extensive aquaculture ponds (blue patches inland)

  12. Dramatic changes in the Dead sea, Jordan over 30 years • 1973: The Sea level is dropping at the rate of 1m/year • 2002: Notice the expansion of salt works, and near-complete closing off of the southern part by dry land

  13. Death of the world’s fourth largest inland sea: Aral Sea, Kazakhstan • 1973: The surface of the sea once measured 66 100 km2 • 1987: 60% of the volume had been lost • 1999-2004: The sea is now quarter of the size it was 50 years ago

  14. Alarming drop in Lake Balkhash’s water level, Kazakhstan Images show alarming drop in lake’s water levels • 1975-1979: Excessive use and waste of lake water are causes of the drop • 2001: Smaller neighbouring lakes appear to be drying up

  15. Changes in Kara-Bogaz-Gol – a lagoon of the Caspian sea, Turkmenistan Caspian Sea is the largest inland body of water in the world • 1988: KBG is the large shallow lagoon of the Caspian sea • 2000: Caspian Sea levels are higher than 1978 levels and water flows freely into salty waters of KBG

  16. Changes due to construction of Three Gorges Dam, China • 1987: Nature of the river and surrounding landscape before the dam • 2004: The enormous dam is clearly visible

  17. Changes in water levels on Lake Hamoun, Iran • 1976: The amount of water in the lake is relatively high • 1999-2001: The lake dried up and disappeared

  18. Demise of an Ecosystem – Mesopotamia Marshlands, Iraq • 1973-2000: Most of the wetlands disappeared Upstream damming as well as drainage activities in the marshlands themselves have significantly reduced the quantity of water entering the marshes

  19. Revival of Mesopotamia Marshlands, Iraq • 2000: Water returns to the Mesopotamian Marshlands • 2004: Greening of some of the Marshlands in recent years

  20. Forest burning in Demilitarized Zone (DMZ) Korea Images reveal significant burn scars in the DMZ

  21. Deforestation in Ouxomxay, Laos • 1975: Image shows continuous forest cover • 2000: Forest cover dotted with cleared patches

  22. Changes in world’s second largest palm oil producing area: Papua, Indonesia • 1990: a new human presence, earth colored roads provide access to the forest • 2000: rectilinear patterns cover 10,000 ha • 2002: Cleared area nearly doubles since 2000

  23. Sundarban: Changes in largest mangrove forest of the world, India/Bangladesh Forest degradation has been occurring in many parts of Sundarbans Shrimp farming is a major threat to mangrove forests

  24. Changes in the largest date palm forest in the world: Shatt al-Arab, Iraq/Iran • 1975-2002: Shows destruction of the largest date palm forest in the world, bordering Iraq and Iran • By 2002, more than 80 per cent of palms were wiped out due to war, salt and pests
