The Value of Satellite-Based Active Fire Data for Monitoring, Reporting and Verification of REDD+ in the Lao PDR

Shifting cultivation is a dominant land-use system in Laos, and fire is the tool commonly used to clear fallow vegetation for subsequent cultivation. We assessed the feasibility of active fire data derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) for monitoring fires in Laos. Specifically, we investigated the potential of the active fire data as input into monitoring, reporting and verification (MRV) systems to assess the effectiveness of measures related to Reducing Emissions from Deforestation and Forest Degradation plus the enhancement of forest carbon stocks (REDD+). Our qualitative and quantitative accuracy assessments of the fire data yielded mixed results with varying degrees of undetected fires and false detections. Hence, at IPCC Tier 3, the uncertainties inherent in the detection accuracy become too large. Active fire data can be valuable for supporting national-level MRV at Tier 2 in combination with auxiliary data for characterizing fire-dependent local land-use systems, such as shifting cultivation.

We acknowledge support from the project entitled Impacts of Reducing Emissions from Deforestation and Forest Degradation and Enhancing Carbon Stocks (I-REDD+). I-REDD + is funded by the European Community’s Seventh Framework Research Programme. More information can be found on the web site: http://www.i-redd.eu. We particularly thank Dirk Pflugmacher, Gernot Rücker and two anonymous reviewers for their excellent comments on earlier versions of this paper. We are indebted to Patrick Hostert, Andreas Heinimann, Gabriel Eickhoff, Kasper Hurni and Conny Hett for comments, discussions and support. We also thank Kasper, Conny and Anouxay Phommalath as well as the volunteers from “Weltwärts” for the collection of ground control points. Discussions on the Google group LaoFAB have generated a number of highly valuable responses, and we acknowledge all experts who replied, particularly the contributions by Dirk Van Gansberghe and Oliver Ducourtieux. Finally, we gratefully acknowledge the Participatory Land and Forest Management Project for Reducing Deforestation in Lao PDR (PAREDD) of the Japan International Cooperation Agency (JICA), which provided the plot-level dataset.
