Preliminary assessment of the knowledge gaps to prevent soil erosion.
Guimarães, M.H.; Martins, M.; Vieira, D.; Brito, I.; Kelly, C.; Guiomar, N.; Stathopoulos, N.; Zoka, M.; Nóvoa, T.; Cerdà, A.; Faria, B.; Madeira, J.SOLO project aims to deliver actionable transdisciplinary roadmaps for future soil-related research and innovation activities in the EU, contributing to the objectives of the EU Soil Mission. To achieve this overarching goal, the project employs a transdisciplinary task force known as Think Tanks (TTs). Comprising 10 Think Tanks, SOLO aligns these entities with the specific objectives established by the EU Miss...
Burned Areas Mapping Using Sentinel-2 Data and a Rao’s Q Index-Based Change Det...
Tiengo, R.; Merino-de-Miguel, S.; Uchôa, J.; Guiomar, N.; Gil, A.This study explores the application of remote sensing-based land cover change detection techniques to identify and map areas affected by three distinct wildfire events that occurred in Mediterranean islands between 2019 and 2022, namely Sardinia (2019, Italy), Thassos (2022, Greece), and Pantelleria (2022, Italy). Applying Rao’s Q Index-based change detection approach to Sentinel-2 spectral data and derived ind...
Fire-Smart Territories: a proof of concept based on Mosaico approach
Pulido, F.; Corbacho, J.; Bertomeu, M.; Gómez, A.; Guiomar, N.; Juárez, E.; Lucas, B.; Moreno, G.; Navalpotro, J.; Palomo, G.Context Here we develop a practical framework (Mosaico) and report a real-world example of early implementation of a Fire-Smart Territory (FST) in Sierra de Gata-Las Hurdes region of central Spain. Objectives We aimed to assess the impact of landscape changes induced by Local Land Managers (LLM; indirect prevention) on simulated fire spread under different governance scenarios developed in 2016–2021. Methods Fo...
The effectiveness of past wildfire at limiting reburning is short-lived in a Me...
Davim, D.A.; Rossa, C.G.; Pereira, J.M.C.; Guiomar, N.; Fernandes, P.M.Background The study of wildfire interactions (i.e., spread limitation and reburns) is gaining traction as a means of describing the self-limiting process of fire spread in the landscape and has important management implications but has scarcely been attempted in Europe. We examined to what extent previously burned areas restricted the development of individual large wildfires (> 500 ha) in mainland Portugal. R...
A Planning Model for Fire-Resilient Landscapes in Portugal Is Riddled with Fall...
Guiomar, N.; Pereira, J.M.C.; Fernandes, P.M.FIRELAN was developed as a model expected to foster the resilience to fire and sustainability of a landscape that is based on a number of premises about fire behaviour. We critically review FIRELAN and find that flawed ecological concepts and terminology are used, and that six fallacies are pervasive throughout the paper, namely begging the question regarding the effectiveness of land cover changes; the appeal ...
Unraveling the Effect of Fire Seasonality on Fire-Preferred Fuel Types and Dyna...
Oliveira, E.; Fernandes, P.M.; Barros, D.; Guiomar, N.Socio-demographic changes in recent decades and fire policies centered on fire suppression have substantially diminished the ability to maintain low fuel loads at the landscape scale in marginal lands. Currently, shepherds face many barriers to the use of fire for restoring pastures in shrub-encroached communities. The restrictions imposed are based on the lack of knowledge of their impacts on the landscape. We...
The effect of broadleaf forests in wildfire mitigation in the WUI – A simulatio...
Oliveira, A.S.; Silva, J.S.; Guiomar, N.; Fernandes, P.; Nereu, M.; Gaspar, J.; Lopes, R.F.R.; Rodrigues, J.P.C.The increasing occurrence of large wildfires in Southern European countries calls for the adoption of more effective measures of fire prevention, to protect people and infrastructures, namely in the Wildland-Urban Interface (WUI). Previous research suggests that broadleaf forests could mitigate the effects of these wildfires due to their lower flammability. However, few attempts have been made to investigate th...
The Portuguese Large Wildfire Spread database (PT-FireSprd)
Benali, A.; Guiomar, N.; Gonçalves, H.; Mota, B.; Silva, F.; Fernandes, P.M.; Mota, C.; Penha, A.; Santos, J.; Pereira, J.M.C.; Sá, A.C.L.Wildfire behaviour depends on complex interactions between fuels, topography, and weather over a wide range of scales, being important for fire research and management applications. To allow for significant progress towards better fire management, the operational and research communities require detailed open data on observed wildfire behaviour. Here, we present the Portuguese Large Wildfire Spread database (PT...
A global assemblage of regional prescribed burn records — GlobalRx
Hsu, A.; Jones, M.W.; Thurgood, J.R.; Smith, A.J.P.; Carmenta, R.; Abatzoglou, J.T.; Anderson, L.O.; Clarke, H.; Doerr, S.H.; Fernandes, P.M.Prescribed burning (RxB) is a land management tool used widely for reducing wildfire hazard, restoring biodiversity, and managing natural resources. However, RxB can only be carried out safely and effectively under certain seasonal or weather conditions. Under climate change, shifts in the frequency and timing of these weather conditions are expected but analyses of climate change impacts have been restricted t...
Marcadores moleculares subrogados a la repelencia al agua en suelos afectados p...
Jiménez-Morillo, N.T.; Almendros, G.; Guiomar, N.; Miller, A.Z.; Barrocas-Dias, C.; de la Rosa, J.M.; Hatcher, P.G.; González-Pérez, J.A.La repelencia al agua del suelo (RAS) se atribuye a la acumulación de compuestos hidrofóbicos (lípidos), pero su extracción no siempre elimina la RAS, lo que sugiere que componentes macromoleculares no extraíbles también pueden estar relacionados con una RAS. Se han estudiado suelos quemados (B) y control (UB) del Parque Nacional de Doñana (Huelva, España) bajo dos tipos de vegetación (alcornoque y brezo) y fra...
