Nam Ton Watershed Group 2 SangHuyToe Cost and Benefit analysis of Irrigation and Agriculture Development

2 Layout  Introduction  Background  Singthong District  Hinherb District

Introduction The purpose of the presentation is to show the real situation of watershed implementation in Sangthom and Hinherb provinces and to show the cost and benefit of this watershed project 12/7/20153

4  KfW, GIZ, LMNC, and MRC support the project  project duration is 2010 to 2017 ( 7 years )  project start from 10/2011  project have two portion ( part 1 – cover all project measures within the project area by Lao Government and the local people ) ( part 2 – MRC facilitates regional water resources development and pilots replicable development solutions Background

12/7/20155 Background (Cont’)  Nom Tom Watershed is part of the lower Mekong Basin and direct tributary to the Mekong River  the project area comprises of 43 villages in Hinheup and Sangthong districts  project area is 80,000 ha  total population is 32,000  propose irrigation site, 8 ( 1, rehabilitation and 7 new )

12/7/20156 Sangthong District  Background  Area: Km2  5 Kum Ban  Forest:38700 h  Population: (F = 14344) 75% is farmer  Agricultural area:29000 h  Rain fed area:7635 h  Yield product:4.15T/h (rain feed) 4.36T/h (irrigated)  Main income:rice growing and aquaculture

12/7/20157 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

12/7/20159 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

12/7/ Hinherb District  Background  Flat land:10%  Mountainous:90%  Population:5900  Irrigated area:14ha  Yield production:2.8T/Ha  Main income:rice plantation

12/7/ The On Going Issue  Lack of irrigation system  Erosion 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 Recommendation & Solution
