Identify the Major Reasons to Cause Vulnerability to Mekong Delta Under the Impacts of Drought and Climate Change
Abstract
The Mekong Delta lies within the humid tropics, characterized by consistently high mean monthly temperatures (25–29 °C) and high but seasonal rainfall (1200–2300 mm). Discharge of the Mekong River exhibits strong seasonal variation in corresponding rainfalls. The low flow period (December to May) occurs during the dry season and the earliest stages of the wet season. The low rainfall and high evaporation during the annual dry season place constraints on human habitation and activity in the Mekong Delta. Such conditions also give rise to other problems such as salinity intrusion in coastal areas and acidification in ASS (Acid Sulfate Soil) areas. Shorter periods of dryness, which occur during the onset, or toward the end, of the wet season in some years, may also be extremely damaging to newly planted crops (Thuan 2006).
