 I'm in charge of developing special analysis and modeling tools to try to see or to try to quantify the potential impact of wood fuel extraction on the environment in terms of mostly above ground biomass. So these models are novel because they include not only special and temporal dimensions but multiple drivers at the same times. In particularly we're trying to model fuel good, charcoal and land cover chain driven by non-wood fuel causes at the same time and in ensemble. The idea here is that if we can validate this data with independent information then it will be a super useful tool for interventionists trying to see which is the impact of cookstores in emissions.
