Methodology technical feasibility NbS 2
The objective of this map is to showcase which areas are suitable for flooded forest reforestation projects.
Improving the flooded forest ecosystem
Flooded forest is a specific type of ecosystem characterized by the regular inundation of water due to the natural flooding of the Mekong River.
Stress & Pressure
Uncontrolled encroachment of the flooded forest has led to declines in fish populations and reduced income from fishery. The conversion of flooded forest to agricultural land has destroyed the vital breeding grounds and nursery habitats for fish.
Upscaling potential maps
The map below shows the suitability of restoration of the flooded forest in Cambodia. Areas in dark green are highly suitable for reforestation.
Potential NbS measures
This case study area is located in Kampong Chhnang province, covering flooded forests along the Tonle Sap River, which connects the Mekong River with the Tonle Sap Lake.
Identify areas that are threatened to deteriorate
According to Kummu and Sarkkula (2008), cumulative impact assessments suggest that dry-season water levels are expected to rise, while wet-season water levels are likely lower than the current conditions.
Identify areas that are worthwhile protecting
By referencing the inundation map created by Kummu and Sarkkula (2008), it is noticeable that certain sections of the flooded forest in Tonle Sap Lake remain unaffected by the inundation resulting from elevated water levels during the dry season.
Upscaling potential
"Approximately 197200 hectares is highly suitable for reforestation - that is roughly 280,000 football fields"
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.
