Anthropogenic Fires in West African Landscapes: A Spatially Explicit Model Perspective of Humanized Savannas
Abstract
:1. Introduction
2. A Hybrid Approach: Fieldwork, Data, and Simulation
2.1. Fire Mosaics in West Africa
2.2. Exploring the Local Context and Fire Ignition Timing to Understand Regular Fire Regimes
2.3. Bottom Up and Spatially Explicit Approach with Agent Based Modelling (ABM)
3. Detailed Methodology: Geographic Information System (GIS) and Geo_Fire Model Description
3.1. Data and Model Preparation (Fieldwork, GIS, and Climate Data)
3.2. Simulations of Contrasting Scenario
- Land cover (LC): this variable allows the fire to propagate or not; it is based on a map built with Landsat scene.
- Raster with first day of potential fire (FDPF): this variable gives the date of the first potential fire by cell, an estimation based on meteorological census data.
3.3. Outputs and Analysis
4. Behaviors and Results of Geo_Fire Model
5. Discussion: A Model to Explore Fire Regimes in their Socio-Ecological Contexts
5.1. Modelling Humanized Savannas: Lessons from West African Landscapes
