Climate changes are a phenomenon that can affect the daily activities of rural communities, with particular emphasis on those directly dependent on the agricultural and forestry sectors. In this way, the present work intends to analyse the impact that climate changes have on forest risk assessment, namely on how the occurrence of rural fires are affecting the management of the forest areas and how the occurrence of these fires has evolved in the near past. Thus, a comparative analysis of the data provided by IPMA (Portuguese Institute of the Sea and the Atmosphere), was carried out for the period from 2001 to 2017 with the climatic normal for the period between 1971 to 2000, for the variables of the average air temperature, and for the precipitation. In this comparative study, the average monthly values were considered and the months in which anomalies occurred were determined. Anomalies were considered in the months in which the average air temperature varied by 1 °C than the value corresponding to the climatic norm, in at least 50% of the national territory. The same procedure was repeated for the variable precipitation, counting as anomaly the occurrence of a variation in precipitation of 50%, also in 50% of the national territory. Then the calculation of the moving averages for cycles of 3, 5 and 7 periods were applied, and the trend lines were projected. Subsequently, the relationship between the results obtained and the occurrence of rural fires as well as the spatial distribution of forest area, species and structure were analyzed. From the results obtained it was possible to confirm the existence of a tendency for the occurrence of climatic anomalies, highlighting the occurrence of an increasing number of months with temperatures higher by at least 1 °C. It was possible to foresee the relation between the occurrence of rural fires and the periods of anomaly and absence of precipitation. From the results obtained it is also possible to infer that, analyzing the tendency for these phenomena to occur, it can be necessary to change the “critical period of rural fires”, since it is verified that what is currently in use does not covers the entire period where anomalies occur and where large-scale rural fires potentially can happen.

“…3) permite obter uma perspetiva geral dos padrões de distribuição do risco de incêndio rural nas freguesias da região Centro do país. Esta abordagem, baseada na delimitação de áreas de maior risco a partir de uma visão integrada das diversas dimensões, permite definir prioridades de intervenção, uma preocupação que se tem refletido nas políticas florestais e de defesa da floresta contra incêndios (DFCI) ao longo do tempo (Pinho e Mateus, 2019). De facto, a definição de zonas mais propícias ou sensíveis à ocorrência de incêndios, tem integrado inúmeros instrumentos legislativos e de planeamento, baseados em diferentes índices de risco com aplicações diversas (Lourenço, 2016;Oliveira et al, 2021).…”

Um índice de risco de incêndio foi aplicado às 972 freguesias da região Centro de Portugal Continental, integrando três dimensões: perigosidade, exposição e vulnerabilidade social. As freguesias do setor centro-sul apresentam níveis de risco mais elevados. Os padrões espaciais variam para cada dimensão; a vulnerabilidade mais elevada ocorre nas freguesias dos setores oriental e centro-sul, enquanto a perigosidade mais alta se localiza numa faixa N-S no setor central da região. As estratégias de redução de risco devem ser ajustadas de acordo com a relevância de cada dimensão.

In the last decades, fire regimes in Europe have changed toward an increased occurrence of extreme fire events with large burned areas and associated impacts. Portugal is one of the countries most affected by wildfires, with extraordinary negative impacts. Postfire emergency stabilization is an important restoration practice to mitigate fire impacts in the short term. The present study aims to improve understanding of how public funding processes affect the efficiency of postfire emergency stabilization in Portugal. We analyzed the process of public funding for postfire emergency stabilization in 2009–2018 using data from public reports assessing the needs for interventions (147), open calls resulting from those reports (12), and implementation projects subsidized by the calls (517). Our results show that available funding through calls for postfire emergency stabilization responded to the needs assessed by previous reports, but there was no available funding (reports and calls) for many (37%) of the large burned areas (>1,000 ha) in 2009–2018. Furthermore, the effectiveness of public funding for postfire emergency stabilization in Portugal is limited by the financial model, lack of eligibility of relevant treatments, the constant change of calls criteria, and slow decision‐making and execution that exceeds the optimal timeframe. As a consequence, implementation of postfire emergency stabilization within an optimal timeframe is halted by insufficient financial capacity of private beneficiaries. We discuss effective funding mechanisms from other countries and suggest improvements for the funding process in Portugal.
