  1. Disease of living styleA case study of parasite disease and rural environment in Pingtung region Michael Shiyung Liu Academia Sinica

  2. The Kaoping Valley

  3. Disease and lifestyle • Certain type of illness could link to specific causation of living style • Kaoping River has been polluted by various forms • human waste, • wastewater from animal husbandry (piggery, cattle, and fowl) • urban rubbish, and industrial hazard etc.

  4. Water supply, hygiene and disease • Epidemiologist Bradley’s classification • Water-borne - caused through consumption of contaminated • Water-washed - caused through the use of inadequate volumes for personal hygiene • Water-based - where an intermediate aquatic host is required • Water-related vector - spread through insect vectors associated with water • “Water-caused” diseases

  5. Water-caused disease in Kaoping Valley • Among all “water-caused” diseases, based on public health surveys in the 1920s and 30s • The gross morbidity rate of parasite-related diseases was 18 per cent • To the causes of death, gastroenteritis was the most important cause of death among the infant and child (ages 0 to 4) mortality problem

  6. Agricultural and early urban diseases(1920s-30s) • Fishery ports and market-towns appeared in the downstream of KaopingValley • Urbanization since the 1930s • urban population increased nearly double animal husbandry • Bringing so many animals into urban proximity they created conditions were epidemic diseases might – and often did – spread rapidly

  7. Ligang: A market-town in midstream • The crisis in the region's irrigation systems in the wake of the 1930s urbanization was directly tied to the simultaneous increase in many parasite problems. • Malaria, paratyphoid and dengue fever

  8. Dengue fever on Nichinichshinpo

  9. Post-WWII development • Certain disease such as Amebiasisindicate the distance between farmer and livestock was very close, especially in the cycle of food-chain • The debate of water pollution in the Kaoping River rise since late-1970s, and in the 80s the debate evolves to series of violent demonstrations till the early 21st century. • The deterioration of water quality links to • bio-waste and chemical pollutants

  10. Animal husbandry and bio waste

  11. Distribution of piggery in Kaoping Valley (1997-2002)

  12. A piggery and untreated waste water

  13. Question • With growth of animal husbandry and regional population, the morbidity rate of enterogastritis however shows a decline trend between 1960s and 1990s • DDT spraying project from 1953 through 1957 • deterioration of water quality since the 1970s • 64.5% from piggery, 20.7% Industrial waste, 13.2 household waste, and 1.6 city rubbish

  14. Life rubbish dumped in Ligang area

  15. Documentary of Pollution in Kaoping Valley

  16. Concluding remarks
