I am working at KWS (Kenya Wildlife Service) in Malindi, as a volunteer of JICA. My job is teacher of environment. This presentation is about environmental archaeology. I will introduce how archaeologists investigate era of relics, by radiocarbon dating method. Then I will look at the fall of the civilization in ancient China, Pompeii, and Maya as case study.

  3. 3. What is Environmental Archeology?• To study how “the dawn, the progress and the fall, of the civilization” occurred under the certain environment.• Archeologists use “Radiocarbon Dating Method” to find out when the found relic created.
  4. 4. “Radiocarbon Dating Method” C14 in Amount atmosphere of C14 C14 in atmosphere is stable. Once organism stop metabolism C14 C14 reduce with time passed. in relic Half term-5730 year Time Passed 5730 year 11460 year Created passed passedCalculate amount of carbon(C14) in relic, then find out the era it created.
  5. 5. ① The War② Natural Disaster ③ Culture / Religion
  6. 6. Case Study: Ancient ChinaQuiz : How many Chinese Dynasty exist? 長江文明 BC14000 唐朝 AD618 黄河文明 BC7000 五代十国 AD907 夏朝 BC2070 遼朝 AD947 殷・商朝 BC1600 宋 AD960 周朝 BC1200 金朝(女真) AD1115 春秋戦国 BC770 元朝 AD1271 秦朝 BC221 明朝 AD1368 漢朝 BC206 清朝 AD1616 三国 AD220 中華民国 AD1949 晋 AD265 隋朝 AD581
  7. 7. Case Study: Ancient China• Until recent, China changed era by war due to feudalism, or bad administration.• Recent research found, era in China changed due to climate change.• And it lead to “want of food”
  8. 8. Case Study: Pompeii / Italy• 24 August in BC79• Eruption of Mt. Vesuvio• Pyroclastic flow hit town• 600℃ volcanic ashes called nueeardente swallowed town People in Pompeii died due to environmental hazard!!
  9. 9. Case Study: Maya / C. S. America• Theory 1: People in Maya abandoned their culture and removed somewhere due to their cultural belief.• According to Maya calendar, next judgment day is 23 Dec 2012.
  10. 10. • Structures were covered by plaster.• All structures build on the slope.• Therefore, once rain fall, water flow on plaster and gathered in one place.
  11. 11. What about Our World Now?• Archeologists usually consider the end of civilization due to terrible governance or civil war.• But, in terms of “the fall of the civilization”, climate change has important roll.• Even today, the war occurs in the Middle East, to have an interest in a water business. = Sh Gasoline 150/L in Japan Water 150/L in Japan
  12. 12. Conclusion• Environmental change such as natural disaster, draught, climate change scarce our food and influence our civilization.• Even today, the war occurs in the Middle East, to have an interest in a water business.
