Abstract:
... Fire can destroy infrastructure and livelihoods, and claim lives. Yet, fire is inevitable and plays several vital ecological roles that have shaped ecosystems over millennia. Planned fires also serve human needs. Critical media content analysis of 390 media reports (print, online and broadcast) on fires in South African National Parks over a three-year period were used to investigate the portrayal ...

Abstract:
... Fuel hazard estimates are vital for the prediction of fire behaviour and planning fuel treatment activities. Previous literature has highlighted the potential of Terrestrial Laser Scanning (TLS) to be used to assess fuel properties. However, operational uptake of these systems has been limited due to a lack of a sampling approach that balances efficiency and data efficacy. This study aims to asses ...

The fuel load equations predict the load of the surface/near-surface and elevated fine fuel. The FHR equations predict the surface, near-surface, combined surface and near-surface, bark, and overall FHR. The utility of the “Overall fuel haz ...

African grassy biomes evolved together with fire and have a long history of human manipulation of fire, yet few rangeland studies acknowledge the role of prehistoric fire in shaping contemporary ecological patterns. Nevertheless, prehistoric fire records have been used elsewhere as invaluable environmental contexts for practitioners in fire management, ecosystem restoration and climate change. The ...

Abstract:
... Government agencies in the United States (US) adopted a prescribed burning policy based in part on paleo-environmental evidence of pre-Columbian Native American burning regimes. However, biomass collection by Native Americans in the pre-Columbian era left little direct or indirect evidence of its magnitude or influence on fire regimes. In many developing countries, local peoples harvest biomass fo ...

Abstract:
... Ten-hour dead fuel moisture content (DFMC10) is an important determinant of wildfire risk, as it provides a reasonable proxy to vegetation flammability. Thus far DFMC10 prediction by physical models has shown limited accordance with empirical measurements. DFMC10 can be measured using fuel-sticks, but to date these are only used in part of the meteorological stations. The goal of this paper is to ...

Storage of fresh comminuted biomass render substantial dry matter and energy losses. Covering can protect wood chips from rewetting, leading to a higher net calorific value and lower dry matter losses, and thus increase the amount ...
