Wildfires continue to cause damage to property, livelihoods and environments around the world. Acknowledging that dealing with wildfires has to go beyond fire-fighting, governments in countries with fire-prone ecosystems have begun to recognize the multiple perspectives of landscape burning and the need to engage with local communities and their practices. In this perspective, we outline the experiences...
The frequent occurrence of fires in Canaima National Park, Venezuelan Guayana, is of great concern in the region. Fire, mostly originating on savannas, is considered a threat because of its impacts upon ecosystems, triggering a process of forest substitution by treeless savannas. In addition, the fires affect the well-being of Pemón indigenous communities, the hydroelectrical industry, and activities...
Savannas constitute the most fire-prone vegetation type on earth and are a significant source of greenhouse gas emissions. Most savanna fires are lit by people for a variety of livelihood applications. ‘Savanna burning’ is an accountable activity under the Kyoto Protocol, but only Australia, as a developed economy, accounts for emissions from this source in its national accounts. Over the past decade...
The authors of this response are part of a multidisciplinary team of professionals in the areas of ecology, sociology, anthropology, mathematics, geography, agricultural and forestry engineering, working since 2007 on the project Factores de riesgo en la reducción de habitats en el Parque Nacional Canaima: vulnerabilidad y herramientas para el desarrollo sostenible (hereafter Proyecto Riesgo) developed...
Abstract African grasses, introduced into Neotropical savannas to improve forage quality, have spread successfully and displaced native plants. To understand their competitive relationships, we compared biomass production and allocation, plant architecture and phenology, net photosynthesis (Pn), water relations, and nutrient content under fire and simulated herbivory between two C4 grasses, the native...
