In the area you have selected (Bangkok) water scarcity is classified as medium according to the information that is currently available to this tool. This means that there is up to a 20% chance droughts will occur in the coming 10 years. Based on this information, the impact of drought must be considered in all phases of the project, in particular its effect on personnel and stakeholders, and during the design of buildings and infrastructure. Project planning decisions, project design, and construction methods should take into account the level of drought hazard. Further detailed information should be obtained to adequately account for the level of hazard.
Climate change impact: Model projections are inconsistent in their estimates of change in drought hazard, which influences water scarcity. The present hazard level may increase in the future due to the effects of climate change. It would be prudent to design projects in this area to be robust to increased drought hazard and water scarcity in the long-term.
