Flood management
1. Under Supervision of the PMO
•Ministry of Labor and Social Welfare•Ministry of Agriculture and Forestry•Ministry of Industry and Handicraft
2. Ad Hoc FM Committee Flow Chart
Flood Mitigation Measures
Floods cannot be controlled;but FMC should be carried out :1. Preparedness for social lives
• Work closely with line agencies concerned• Check the flood protection sluice• Install pumping stations• Manage embankment and dykes • Manage Nam Ngum Dam operation• Lay down the sandbags• Help Villagers (in case emergency)
2. Flood Response :
MAF, MLSW, NDMC have worked closely with provincial and local authorities:
• Got data & information on flood situation (whole country)
• Provided seed for farmers/villagers after floods withdrew
• Requested assistance from donors• Arranged technical staff, tools and equipment for
helping flood victims
3. Activities carried out during & after floods 2002
• Authorities concerned visited flood areas • Sent technical staff to flood areas to collect data
& information on social & economic damage• Prepared the second crops, nursery ponds, etc• Coordinated with local authorities to help flood
victims with drinking water and food
RecommendationA. Immediate future: 2005-2010
• Civil construction & infrastructures built above flood level
• Agricultural production :• Cultivation will be started once flood withdraw
• Cropping patterns & varieties change will be applied to double crops: October to July
• Selection of appropriate crop patterns so that flood risk can be prevented (managed)
• For frequently flooded areas along Mekong river & its tributaries, optimum solution is “Stay with flood”
• Residential accommodation works & industrial zones will be removed to higher locations
• Flood forecasts & floods warning will be extended to communities on time
• Improved & extended communication systems
• Relief to flood victims
B. Long term period after 2010
• Construction of dikes, sluices & drainage pumping stations required to control & mitigate floodwater from Mekong river & tributaries
• Embankments & dyke systems to control early flood
• Water logging drainage structures will be constructed in combination with flood control structures
• Build on-farm drainage systems in specific areas
• Meteo-hydrological stations should be completed including rain-gauge stations
• Information & data need to be collected & update annually on losses and damage caused by flood, flood marks, flood duration, flooded areas etc….These will be synthesized to assess flood reasons
• Residential areas will be removed to the upper areas
Thank you!
