The pyrogeography of sub-Saharan Africa: a study of the spatial non-stationarity of fire–environment relationships using GWR [PDF]

open access: yesJournal of Geographical Systems, 2010
This study analyses the relationship between fire incidence and some environmental factors, exploring the spatial non-stationarity of the phenomenon in sub-Saharan Africa. Geographically weighted regression (GWR) was used to study the above relationship. Environment covariates comprise land cover, anthropogenic and climatic variables.

Measurement of inter- and intra-annual variability of landscape fire activity at a continental scale: the Australian case

open access: yesEnvironmental Research Letters, 2016
Climate dynamics at diurnal, seasonal and inter-annual scales shape global fire activity, although difficulties of assembling reliable fire and meteorological data with sufficient spatio-temporal resolution have frustrated quantification of this ...

Machine Learning Model Reveals Land Use and Climate’s Role in Amazon Wildfires: Present and Future Scenarios

open access: yesFire
Understanding current fire dynamics in the Amazon is vital for designing effective fire management strategies and setting a baseline for climate change projections.

Wave of fire: an anthropogenic signal in historical fire regimes across central Pennsylvania, USA

open access: yesEcosphere, Volume 9, Issue 5, May 2018., 2018
Abstract Increasingly detailed records of long‐term fire regime characteristics are needed to test ecological concepts and inform natural resource management and policymaking. We reconstructed and analyzed twelve 350+ yr‐long fire scar records developed from 2612 tree‐ring dated fire scars on 432 living and dead pine (Pinus pungens, Pinus rigida, Pinus

Global variation in ecoregion flammability thresholds

open access: yesEcography, Volume 2024, Issue 7, July 2024.
Anthropogenic climate change is altering the state of worldwide fire regimes, including by increasing the number of days per year when vegetation is dry enough to burn. Indices representing the percent moisture content of dead fine fuels as derived from meteorological data have been used to assess geographic patterns and temporal trends in vegetation ...

Can We Go Beyond Burned Area in the Assessment of Global Remote Sensing Products with Fire Patch Metrics?

open access: yesRemote Sensing, 2016
Global burned area (BA) datasets from satellite Earth observations provide information for carbon emission and for Dynamic Global Vegetation Model (DGVM) benchmarking.

Megafire: An ambiguous and emotive term best avoided by science

open access: yesGlobal Ecology and Biogeography, Volume 33, Issue 2, Page 341-351, February 2024.
Abstract Background As fire regimes are changing and wildfire disasters are becoming more frequent, the term megafire is increasingly used to describe impactful wildfires, under multiple meanings, both in academia and popular media. This has resulted in a highly ambiguous concept.

Have Historical Land Use/Land Cover Changes Triggered a Fire Regime Shift in Central Spain?

open access: yesFire, 2019
Fire is one of the main disturbance factors shaping the landscape, and landscape is a key driver of fire behavior. Considering the role played by land use and land cover (LULC) changes as the main driver of landscape dynamics, the aim of this study was ...

Pyrogeography: integrating and evaluating existing models of Australian fire regimes to predict climate change impacts

open access: yes, 2013
The working group aimed to address important knowledge gaps in the biogeography of fire in Australia by: (1) Developing an approach to classifying and mapping broad fire regimes at a continental scale. A continental description of the diversity of fire regimes is a key step in understanding the global drivers and constraints of landscape fire, as well ...

Archaeological evidence of anthropogenic burning for food production in forested uplands of the Grand Canyon province, northern Arizona

open access: yesFrontiers in Environmental Archaeology
Despite convincing archaeological arguments about the global effects of human pyrogeography and their evolutionary significance, many of the implicated data sources are unavailable in research contexts that lack significant accumulations of charcoal or ...
