Celso specialises on the effective management of artisanal and small-scale mining (ASM) on regional and national scales using remote sensing and Geographic Information System (GIS).

The effective management of artisanal and small-scale mining (ASM) on regional and national scales must be based on good understanding of land and water footprints. The diffuse, dynamic and often remote nature of ASM means that traditional ground-based surveys are likely to be impractical except for local scale studies. Remote sensing offers a low-cost option for surveying land use changes and water turbidity, and quantifying the impact of ASM on water quality. However, there are questions about the reliability of remote sensing products for these tasks, and there is a need for recommendations about suitable products, data resolutions and analysis techniques. A case study of the Addalam river basin in the Cagayan region, situated in Luzon forming a part of the Philippine archipelago, was used to address these research questions. The value of alternative satellite products was tested using independent sources of land use, suspended sediments and turbidity data from project partners OceanaGold (Philippines), International RiverFoundation, and local government agencies.
