Context

Flooded forest is a specific type of ecosystem characterized by the regular inundation of water due to the natural flooding of the Mekong River, the area surrounding the Tonle Sap Lake, and the connecting river between the lake and the Mekong River.

Reference alternative

The reference alternative is the scenario in which the NbS will not be implemented at the case study site or in any of the suitable areas.

Project alternative

The project consists of restoring or creating flooded forest areas.

Identification and selection of effects

The identification of effects is one of the most important steps and is done by comparing the project alternative with the reference alternative and identifying the incremental costs and benefits of the project alternative.

Benefits

At the project site, fish catches have reportedly decreased by 30-40% since 2018.

Costs

The table below gives an overview of the costs estimates for the project site and basin. Note that these estimates are all very indicative and based on currently available data.

Discussion of results

The table below shows the results from the CBA. The results are indicative due to the assumptions being made, but some conclusions can be drawn from them.

Financial analysis

To make parts of projects financially viable, they need to generate tangible revenue streams that can be captured by a stakeholder.
