Fire emissions are a critical component of carbon and nutrient cycles and strongly affect climate and air quality. Dynamic global vegetation models (DGVMs) with interactive fire modeling provide important estimates for longterm and large-scale changes in fire emissions. Here we …
Land use contributes to environmental change, but is also influenced by such changes. Climate and atmospheric carbon dioxide (CO2) levels' changes alter agricultural crop productivity, plant water requirements and irrigation water availability. The global food system needs to …
The unprecedented use of Earth’s resources by humans, in combination with increasing natural variability in natural processes over the past century, is affecting the evolution of the Earth system. To better understand natural processes and their potential future …
This study describes and evaluates the Fire Including Natural & Agricultural Lands model (FINAL) which, for the first time, explicitly simulates cropland and pasture management fires separately from non-agricultural fires. The non-agricultural fire module uses empirical …
In this dissertation, I explore the role that agricultural fire management plays in global patterns of vegetation fire and thus carbon cycling between ecosystems and the atmosphere. No estimates previously existed of the amount of fire associated with pasture and rangelands at …
Biomass burning impacts vegetation dynamics, biogeochemical cycling, atmospheric chemistry, and climate, with sometimes deleterious socio-economic impacts. Under future climate projections it is often expected that the risk of wildfires will increase. Our ability to predict the …
The timing and length of burning seasons in different parts of the world depend on climate, land-cover characteristics, and human activities. In this study, global burned area estimates are used in conjunction with global gridded distributions of agricultural land-cover types …
