The Ca River basin is a transboundary river basin shared between Laos and Vietnam.
Existing water use - Farmers commonly plant rice in a double cropping pattern during a year. Three water reservoirs (Ban Ve, Khe Bo and Hu Voc Mau) have already been built to supply water for agriculture, urban areas flood control and hydropower generation. For the baseline period of 15 years (2001-2015), the average agricultural yield was 2929 kg/ha. Also, the average urban water demand coverage (supply) was about 97% and 717 gigawatt-hour hydropower energy was generated.
Key Water management problem - Irrigation demand is not always completely met and irrigation deficits lead to crop yield reductions.
In this game, you, the player, will make development decisions for a river basin. You play the role of a water resources manager. Your task is to make decisions for the next 15 years that are good for multiple sectors: agriculture, urban water supply, hydropower, environment, and flood management. The decisions you make will be evaluated under 3 climates reflecting climate uncertainty: current climate, dry climate and wet climate.
You know that there has not been enough water to maximize agricultural yields
(mostly rice) in this basin.
Can new dams provide more water for agriculture, enabling a third rice crop? Perhaps dam operation could be changed to favor a particular sector. Perhaps increasing the water capacity of canals could help deliver more water.
You can try out these decisions, in each of 5 trials of this game. The schematic below gives you a general idea of the layout of the basin. In each trial, make your choices in the panel to the right, and click 'Submit'.
The model will take your inputs, and run on the server. It will take about 2 minutes to run each trial. Results will be presented for each trial. You can compare your development decisions and results from each trial.
The baseline (the past) has a score of 0. If you get a score:
|Future dam||Change the operation purpose of Ban Ve reservoir||Third crop||Increasing irrigation capacity|
|Ban Mong||Thac Muoi||Ngan Truoi||Flood control||Hydropower generation||Urban and agriculture demand supply||Third crop of rice||North||South||Ha Tinh|
