Los ecosistemas tropicales albergan una gran parte de la biodiversidad mundial y a pesar de ello están siendo transformados por el cambio de uso de la tierra a un ritmo sin precedentes. La conversión de la cobertura de la tierra y el mantenimiento de pastos y áreas para cultivos en Latino América están altamente relacionados con el uso del fuego. El origen de los incendios y sus causas son numerosos y en la región es clara su asociación de forma directa o indirecta con actividades humanas. Suramérica está siendo cada vez más afectada por los incendios y desde el 2001 en todos los años se ha detectado actividad asociada al fuego. Los impactos de los incendios sobre los ecosistemas naturales son múltiples y varían en magnitud, pero se ha avanzado poco en su conocimiento. Este artículo presenta una recopilación del conocimiento que se tiene en ecología del fuego tropical en los tres países andinos del norte de Suramérica, mostrando los avances en los patrones espaciales y temporales de los incendios, los efectos sobre los ecosistemas y las dinámicas post incendio. Se evidencian grandes vacíos del conocimiento en la ecología del fuego de gran parte de los ecosistemas de esta región.

“…Se seleccionaron tres zonas con alta ocurrencia del fuego (Figura 1): Bosques Amazónicos de Colombia en proceso de fragmentación y cambio en el uso del suelo con alta ocurrencia del fuego (Armenteras et al, 2017); Bosque Amazónico en transición a Bosque Chiquitano de Bolivia, notablemente afectado por el fuego (Rodríguez-Montellano et al, 2015) y sometido a procesos de fragmentación por el cambio en el uso del suelo (Devisscher et al, 2015); y un área de El Chaco seco de Argentina, región que está entre las más afectadas por el avance de la frontera agrícola a escala global (Sofía et al, 2017). En general el aumento de la demanda global de productos agrícolas implica también un avance en el proceso de intensificación y expansión de las fronteras agrícolas.…”

<p>There are large omission errors in the estimation of burned area in map products that are generated at a global scale. This error is then inherited by other models, for instance, those used to report Greenhouse Gas Emissions using a “bottom up” approach. This study evaluates temporal methods to improve burned area detection using Landsat 5-TM and 8-OLI. In this process, the normalized burn ratio (NBR) was used to highlight burned areas and thresholds to classify burned and non-burned areas. In order to maximize the burned area detection two alternatives to the temporal dNBR method were evaluated: the relative form of the temporal difference RdNBR and the use of time series metrics. The processing, algorithm development and access to Landsat data was made on the Google Earth Engine GEE platform. Three regions of Latin America with large fire occurrence were selected: The Amazon Forest in Colombia, the transition from Chiquitano to Amazon Forest in Bolivia, and El Chaco Region in Argentina. The accuracy assessment of these new products was based on burned area protocols. The best model classified 85% of burned areas in the Chiquitano Forests of Bolivia, 63% of the burned areas of the Amazon Forests of Colombia and 69% of burned areas in El Chaco of Argentina.</p>

“…Her notable works include an assessment of the patterns and drivers of deforestation in the Colombian Amazon [197] and a study of the influence of forest fragmentation on fire occurrence and intensity in forests in Amazonia [198]. Her recent works include evaluating changing patterns of fire occurrence in tropical Amazon forests [199] and predicting reducing emissions from deforestation and forest degradation (REDD) deforestation rates from remote sensing fire products [200].…”

Across the breadth of fire science disciplines, women are leaders in fire research and development. We want to acknowledge some of these leaders to promote diversity across our disciplines. In Fire, we are also happy to announce a new Special Collection, through which we will continue to acknowledge current and future Diversity Leaders in Fire Science by inviting contributions from the leaders in this editorial, among others.Keywords: leadership; women in science The Need to Recognize Women Leaders in Fire ScienceIn 1965, Alice Rossi asked a fundamental question: "Why so few women in science?" [1]. It has long been recognized that women are underrepresented in science, technology, engineering, and mathematical (STEM) disciplines, with a substantial dialogue in the literature as to the impacts of such underrepresentation. As representation has increased, the debate now focuses on additional questions of equity in leadership, funding, advancement, and mechanisms of support for female scientists. These questions are embedded in three foundational concepts: (1) all scientists, regardless of gender, deserve equal access to opportunities; (2) the smartest and most talented people (regardless of gender) should be conducting scientific research, such that the most critical breakthroughs and contributions are realized; and (3) to understand and solve complex fire science problems, a broad diversity of perspectives, modes of problem attack, and epistemologies are needed [2]. We also acknowledge the need to recognize other underrepresented voices in the fire science community, such as indigenous and racial minorities, individuals with disabilities, and the LGBTQIA community, who all bring different ways of doing and knowing to science.The reader may understandably ask: Why this journal? In fire science, there is a distinct and critical need to increase the recognition of women. Natural hazards research more broadly has widely recognized that women are more vulnerable to natural disasters, and female scientists in other natural hazard disciplines have brought an important perspective to the research that facilitates understanding and reducing such gender disparities. An equivalent gender dialogue does not yet exist in wildfire science but will be necessary to reduce vulnerabilities (e.g., smoke impacts on health, post-traumatic stress disorder following evacuation) and also understand the unique perspectives women have on wildfire as an ecological process. For example, women globally bear much of the childrearing duties; a key fire science question one might ask is whether acceptance of prescribed fire by communities is gendered based on perceptions of impacts to children? The reader may also question the mixed genders of the authors of this editorial. Many proponents of increased recognition of women in science have highlighted that a major part of the problem has been that not enough male allies stand up publicly for their female colleagues, in part because some are embarrassed, fearful, or even feel, and are so...
