Description:

This project aims at gaining accurate information on the use of fire in traditional agriculture and the way fire harms ecosystems in order to develop sound recommendations to optimize slash-andburn cultivation methods and preserve the forest’s biodiversity.

To do so we determine the potential value of the secondary vegetation from an ecological point of view and with a potential  land-use perspective (agriculture), considering the various post-fire succession types.

The specific goals are:

  • to classify post-fire vegetation in the dry forest of Central Menabe and characterising the soil-vegetation patterns,
  • to assess quantitatively and qualitatively the biomass of the secondary vegetation (plots) after fire events,
  • to quantify the potential nutrient inputs from burning biomass (contribution of dominant species),
  • to carry out tests of inflammability of the various tree species and determining their flammability properties,
  • to define the best use (optimization) of secondary vegetation in order to limit incursion in the virgin forest.
