About
In 2018, the Cambodian and Thai governments initiated a bilateral cooperation under the Joint Project on Flood and Drought Management in the 9C-9T Sub-basin. Both parts of the sub-basin, and hence the two countries, are bound together in their shared management challenges and solutions. The shared 9C-9T sub-basin area encompasses the Tonle Sap basin upstream in Thailand and the Stung Mongkol Borei basin downstream in Cambodia, flowing down to the Tonle Sap Lake. The overarching objective of this regional cooperation project is to strengthen resilience and mitigate flood and drought within the shared 9C-9T sub-basin.
This 9C-9T Basin Atlas is a foundational tool that supports a web-based platform for shared knowledge, information and data to inform transboundary, national and sub-national basin planning, management and investment in building resilience to flood and drought.

Nature-based Solutions
The Nature-based Solutions (NbS) catalogue presents a range of NbS with potential to build flood and drought resilience in the 9C-9T sub-basin. Concise good practice summary sheets are provided for over 50 measures applicable to the 9C-9T and measures are categorised into upstream hydrology, agriculture and urban landscapes. Information is displayed in an interactive factsheet that can be downloaded for offline use and reference.
Document
The Atlas document page provides users with a User Manual and a number of key project reports. A list of project events is also included on this page.

Mekong River Commission Joint Project on Flood and Drought Management
Project Description
Donor: German Federal Ministry for Economic Cooperation and Development (BMZ), implemented by GIZ.
Partners: International Centre for Environmental Management (ICEM), Consultants of Technology Co., Ltd. (COT) and Phnom Penh International Consultants (PPIC)
Duration: 2018 - 2024 | Location: Cambodia and Thailand
About: The Deutsche Gesellschaft für Internationale Zusammenarbeit GmbH (GIZ) on behalf of BMZ is implementing the Technical Cooperation (TC) module Transboundary water cooperation in the Lower Mekong Basin, which aims at improving cooperation between Mekong River Commission (MRC) Member States and strengthening governance in the water resources sector in order to balance competing uses of water in the Lower Mekong Basin (LMB). The Joint Project on transboundary cooperation for flood and drought management in the Cambodian-Thai 9C-9T Sub-basin is currently in its third Phase (2022-2024), with Phase one completed in 2019 and Phase two completed in December 2021. The 9C-9T Basin Atlas was a key output of Phase 2, developed by ICEM.
Phase three builds on an initial assessment of flood and drought risk, through four core work packages to:
- Strengthen cooperation on transboundary planning
- Identify potential funding sources and mobilise resources to finance priority flood and drought management measures in the 9C-9T sub-basin
- Prepare expanded baseline assessment to complement the results of the Joint Project by providing deeper insights on climate change, hydrology, land degradation, natural resource management and gender and vulnerability considerations
- Provide technical support with the development of a suite of tools – including the 9C-9T Basin Atlas, supporting integrated planning and flood and drought management
- Deliver capacity building for key stakeholders actively involved in the development and implementation of the Joint Project for flood and drought management
- Planning a transboundary flood and drought early warning system in the Tonle Sap sub-basin
9C-9T Joint Project Inception Report
The 9C-9T Inception Report outlines the recommended methodological approach for each package and defines the interlinkages and dependencies between them. Activities, work plans, personnel and deliverables are described in detail. Through implementation of the approach set out in this report, Phase II will deliver both stand-alone outcomes and significant progress in meeting the overall goals of the Joint Project. The guiding principles for project design outlined in Chapter 3 of this report will ensure that transboundary aspects, gender aspects, vulnerable groups, climate change adaptation and ecological sustainability are consistently applied.
Flood and Drought Master Plan for 9C-9T Sub-basin
The Master Plan is a dynamic framework for joint investment and action supported by the Mekong River Commission (MRC) and international partners. The Master Plan is developed in alignment with the National Indicative Plan (NIP) 2021-2025 prepared by each country to capture the benefits of regional cooperation according to Basin Development Strategy (BDS) for the Mekong River Basin 2021- 2030 and the MRC Strategic Plan 2021-2025.
This Master Plan is the integration of the collaborative work on flood and drought resilience by Cambodia and Thailand since the beginning of the Joint Project in 2018. This Master Plan commits the two countries to strategic priority areas and the accompanying action plan, as identified through this joint planning process, to rehabilitate the watershed of the 9C-9T sub-basin as the foundation for flood and drought resilience. Detailing of the action plans outputs, the delegation of responsibilities within the binational governance structure, and the preparation of associated feasibility studies are all tasks to be conducted within the implementation phase. This will include detailed studies of transboundary impacts and preparation of environmental impact assessment and approvals as required under the national legislation of each country.
A Network of Nature based Solutions to Implement Component 2 of the 9C-9T Flood and Drought Master Plan 2022-2026. Initial Project Concepts
The report sets out concepts for nature-based solutions (NbS) to be demonstrated within a network of collaborative projects conducted by Cambodia and Thailand for strengthening urban and rural flood and drought resilience in the 9C-9T sub-basin. An initial set of six NbS project concepts are outlined, to reduce the risks of flood and drought in specific locations, as the targets for priority investment under the 9C-9T Flood and Drought Master Plan. These cover three degraded landscapes in each country that are in urgent need of restoration. Each project concept presents a network of NbS and hybrid interventions to build flood, drought and ecosystem resilience. The NbS project descriptions are at the conceptual stage for further development with lead implementing agencies during the 9C-9T Master Plan implementation during 2023 onwards. This report is intended as an initial roadmap for use by agencies responsible for 9C-9T Master Plan Outcome 2 implementation.

9C-9T Gender and Social Vulnerability Assessment and Action Plan
The 9C-9T Gender and Vulnerability Assessment report outlines how gender and vulnerability considerations may be incorporated into the Joint Project, specifically through its guiding Master Plan and Action Plan. The assessment aims to define how the action plan for the 9C-9T Master Plan implementation can be designed for sensitivity and for the inclusion of women and socially vulnerable populations. This document presents the result of a brief, high-level Gender and Vulnerability Assessment and an associated, resultant Gender and Vulnerability Action Plan (G-VAP).
Economic Analyses on Nature-based Solutions for Flood and Drought Resilience of the 9C-9T sub-basin. Inception Report
The economic analysis to be conducted in this study aims to evaluate the performance of proposed NbS for the 9C-9T sub-basin in Cambodia and Thailand. This study will focus on two rural landscapes – Ang Trapeang Thmor (ATT), Cambodia and Sompoi Reservoir, Thailand – and a transboundary urban landscape – comprising Poipet, Cambodia and Aranyaprathet, Thailand – in the 9C-9T river basin. This analysis will take account of the likely scenarios and impacts of climate change.
The analysis will provide an initial understanding of the context and applicable tools for evaluating NbS and will also aim to build an economic case for more widespread investment in NbS. It also partially fulfills the 9C-9T Masterplan's output 1.3.1. “to conduct economic valuation of ecosystem services to assess benefits of climate-sensitive gender-sensitive, ecosystem-based adaptation for flood and drought resilience measures”.
