Vegetation change Mekong River

Quantification of vegetation change in upper and middle Mekong River watershed using spaceborne remote sensing data

Funded by: VLIR South Programme

Research associate: Zhang Zhiming

Promoter: Robert De Wulf

Duration: 2003-2010


Project objectives

  1. Developing a procedure to produce, multi-temporal vegetation maps for the two mountainous areas, with special emphasis on high accuracies of these maps and spatial resolution requirements;
  2. Accurately detecting vegetation change in the two study areas, with special emphasis on vegetation transitions (from-to change);
  3. Quantifying vegetation changes for the two mountainous areas, and understand the vegetation change processes (disturbance and fragmentation);
  4. Analysing the correlations between vegetation changes and the driving forces (i.e. topography factors, socio-economic factors, and policies), and quantifying and modelling the driving forces behind these changes;
  5. Modelling and predicting vegetation change by integrating the driving forces.
