““During September and October my house is flooded two times During September and October my house is flooded two times per day at high tide and the water level is this much [c20cm] per day at high tide and the water level is this much [c20cm] from the floor. Because the environment is polluted, each time from the floor. Because the environment is polluted, each time

“We became poor after the flood of 2000. The flood totally destroyed our shrimp pond and we had no income. Now, in each flood, we feel stress and worry about being jobless and not having enough food – this causes sleeplessness, strain and quarrel between family members.” (resident, My Ngai commne, Cao Lanh)
