Software For Monitoring Forest Change In Tropical West Africa Using Satellite Remote Sensing, Michael Wimberly Sep 2020

Software For Monitoring Forest Change In Tropical West Africa Using Satellite Remote Sensing, Michael Wimberly

International Congress on Environmental Modelling and Software

Satellite remote sensing is an essential source of data on forest landscape change that is necessary for estimating carbon stocks, assessing biodiversity, and developing conservation plans to sustain ecosystem services. The Upper Guinean Forest region of West Africa, a global biodiversity hotspot, currently lacks timely, consistent, and accurate long-term forest monitoring systems suitable for decision support. Major limitations include data gaps due to frequent cloud cover and limited satellite coverage. To address these limitations, we developed the West African Forest Degradation Data System (WAForDD) to use all available Landsat imagery to monitor forest change in the tropical forest zone of …

International Congress on Environmental Modelling and Software

The Agricultural Ecosystems Services (AgES) distributed watershed model is being developed as a component-based model for continuous daily simulation. Current case studies use AgES to simulate space-time patterns of soil moisture and infrequent runoff events in a dryland field-scale watershed in northern Colorado, contributions of irrigated agriculture to a mixed-landuse watershed near metropolitan Denver, and tile drainage contributing to high nitrate loads in Iowa, USA. These watersheds (56 ha to 581 km2) provide comparative studies to address model complexity across various scales with different types and amounts of data. Key advances include enhanced process simulation (1) coupling plant uptake of …
