9C9T Atlas

About

Since 2018, Cambodia and Thailand have worked together to achieve joint benefit through transboundary management of flood and drought via the Joint Project on Flood and Drought Management in the 9C-9T Sub-basin. The shared 9C-9T sub-basin area encompasses the Tonle Sap basin upstream in Thailand and the Stung Mongkol Borei basin downstream in Cambodia, eventually carrying water and nutrient to the Tonle Sap Lake. The overarching objective of this regional cooperation project is to increase capacity for transboundary integrated water resources planning and improved water security with consideration to future flood and drought patterns.
This 9C-9T Sub-basin Atlas is a foundational tool that supports these objectives with a shared knowledge and information to inform joint basin planning, management and investment in building resilience to flood and drought. Learn more...

Atlas Map Viewer

Map Viewer is an interactive geospatial mapping tool that allows users to play with spatial layers associated with five key areas of importance to flood and drought management in the context of climate change: Environment, Social, Economics, Climate Change, and Resilience Building.

Map Gallery

The 9C9T map gallery includes an extensive list of beautiful and innovative maps on major topics. Maps are classified by themes (base maps, drought/ flood disasters, natural resources, landuses/ landcovers and climate change). Users can view the maps and be further searched by keyword.

Nature-based Solutions

This catalogue presents a range of nature-based solutions (NbS) with potential to build flood and drought resilience in the 9C-9T sub-basin. The NbS are grouped by different sectors and purposes. Information on each NbS is displayed on a factsheet that can also be downloaded for future reference.
