New tool to better manage fire in African savannas

A new series of graphs, known as nomographs, have been developed to help manage fire in Africa's Sudanian and Sahelian savannas. In these areas, naturally occurring wildfires are critical to maintaining biodiversity and ecosystem function.

BioMedicine reports on a study by the World Agroforestry Centre and partners into the optimal conditions for setting early-season prescribed fires. When executed and timed properly, these fires reduce the risk and impact of late dry season bushfires on increasingly fragile ecosystems.

Previously, land managers in these areas had to rely on less accurate methods to determine what to burn, when to burn it, and to what extent. The nomographs consider both fuel characteristics and weather conditions. They build on age-old practices to create a modern-day tool for managing fires and ecosystems in West Africa.
