Suurin Mekong-joen virtaamaa muuttava tekijä = vesivoimapadot Muitakin muutoksia: kasteluhankkeet, maan käyttö, veden laatu…  Vesivoimalle ja muulle kehitykselle sinänsä tarvetta  HAASTE: hyödyt ja haitat eri alueille ja ryhmille MAP: Matti Kummu / TKK IAG Yangtze Fluvial Conference in Shanghai, China
