Vietnam finalizes study on Ecological Stratification linked to REDD+

As a country aiming to reach Tier 3 reporting by the eventual implementation phase of REDD+, Viet Nam, supported by the UN-REDD Programme engaged in a study to stratify the country into ecological zones which are conducive for forestry. The Ecological Stratification study of Viet Nam was finalized in October 2011.

The study identified first the factors which determine ecological zones, and the hierarchy of such factors, which became the basis for stratifying the national territory into two ecological zones, further stratified into eight ecological regions, further stratified into 47 ecological sub-regions.

This preliminary study is proposed to undergo further national scientific reviews to determine adaptability for the forestry sector in general, and for REDD+ purposes in particular. The study was undertaken by a consultative group of national experts representing the different disciplines which affect forest ecology, and was led by the Research Centre for Forest Ecology and Environment of the Forest Science Institute of Viet Nam.

Viet Nam’s forests demonstrate great diversity owing to the various impacting ecological factors. To date, Viet Nam uses an ecological zoning system which was primarily established as an agro-ecological zoning system with minor adaptations for the forestry sector. Under REDD+, estimation of emission factors of forests are a central activity for MRV. Emission factors differ for each forest type and also depending on the environment or ecological conditions of the forest.
