Half-Century Changes in LULC and Fire in Two Iberian Inner Mountain Areas

Abstract

Wildfires in the Iberian Peninsula were large and frequent in the second half of the 20th century. Land use and land cover (LULC) also changed greatly. Our aim was to understand the relationship between LULC and fire in the western and eastern ends of the Iberian Central Mountain System. We compared two case study landscapes, the Estrela massif and the Ayllón massif, which are biophysically similar but with different social-ecological contexts. In both, fires were in general more likely in shrublands and pastures than in forests. Shrublands replaced forests after fires. Contrasting LULC in the two massifs, particularly pastures, likely explained the differences in fire occurrence, and reflected different regional land use policies and history. Fire here is a social-ecological system, influenced by specific LULC and with implications from landscape to regional scales. Understanding how LULC changes interact with fire is powerful for improving landscape and regional planning.

Hotspot Analysis of Structure Fires in Urban Agglomeration: A Case of Nagpur City, India

“…RS integrated with GIS has many applications in the various fields of weather, forestry, agriculture, surface changes, biodiversity, and many more [30]. In the urban planning context for fire services, RS technologies can be used for detecting land use and land cover (LULC) with active fires (hotspots) determining the physical properties of land with accuracy and precision [11,31,32], quantifying the built-up land for allocation of fire service resources and enhancing the efficiency of emergency responses with sustainability.…”

Dinâmicas de uso e ocupação do solo entre 1951-80 e 2018 em Portugal Continental

“…Por último, até 2018, são referidas dinâmicas de expansão urbana, reflorestação, e alterações no padrão das manchas agrícolas (MENESES et al, 2018, ALVES et al, 2022. A CLC e COS também deram origem a diferentes casos de estudo de análise de dinâmicas de uso e ocupação do solo a nível regional (FERNANDES & ABRANTES, 2011;FREIRE et al, 2014;SEQUEIRA et al, 2019) e local (ABRANTES et al, 2018;FARIA DE DEUS & TENEDÓRIO, 2021). No entanto, todos estes estudos estão limitados pelo ano de início das séries cartográficas referidas, i.e., 1990, e, portanto, conseguem apenas informar a partir da época das grandes mudanças na paisagem Portuguesa que advieram da recente adesão de Portugal à União Europeia, em 1986.…”
