The On Going Issue

District propose to the project on supporting for gate construction at the mouth of Nam Ton river

The dam will protect the upstream from flood meanwhile it also block fish from travelling from Mekong River to Nam Ton river

Shifting cultivation Soil degradation Deforestation

8

New Sluice gate above junction

prevent entering water from Mekong River in high water season

can be used to control flood

can be used to irrigate rice field in dry season

•Block fish migration

Recommendation

To ensure the sustainability of fish caught in this area, in the designing phase of water gate/dam, the fish ladder/ fish stair should carefully design

Shifting cultivation Plan rotation, and Perennial tree

Fish Ladder

The On Going Issue

Lack of irrigation systemErosion is continue on the poor existing irrigation system

Upland agriculture system by applying water harvesting onto the mountainous area (forest conservation should also consider) 5 potential irrigation system are propose
