Wildfires, a key socio-environmental challenge in Mediterranean regions, are influenced by anthropogenic factors shaping land-use and socioeconomic spatial structures. By assuming that the dominant socioeconomic structure of local districts exerts a variable impact on wildfire spatial regimes, the present study investigates 174 indicators on a municipal scale in Italy, identifying a multidimensional relationship between wildfire characteristics and socioeconomic contexts. An exploratory statistical approach was adopted to identify linear and non-linear relationships among variables assessing socioeconomic contexts and wildfire patterns. Empirical results demonstrate that characteristic wildfire attributes (frequency, intensity and severity) are systematically higher in socioeconomic contexts characterized by rural poverty, unemployment and deregulated urban expansion, especially in southern Italy. A higher fire frequency was typically observed in (i) peri-urban districts with a dynamic socio-demographic profile and (ii) in rural districts with intensive cropping systems. Joint information on socioeconomic structure/dynamics and environmental change, is crucial for a better understanding of local-scale spatial patterns of wildfires in the Mediterranean region. Integrated socio-environmental information provides a better understanding of the local communities' role in the management of wildfire-prone land, contributing to implement more effective strategies aimed at minimizing wildfire impact on land resources.
野火是地中海地区的一个主要社会-环境挑战,受到塑造土地利用和社会经济空间结构的人为因素的影响。本研究假设地方行政区的主导社会经济结构对野火空间格局产生可变影响,在意大利的市级尺度上调查了 174 个指标,确定了野火特征与社会经济背景之间的多维关系。采用探索性统计方法来确定评估社会经济背景和野火模式的变量之间的线性和非线性关系。实证结果表明,在以农村贫困、失业和不受管制的城市扩张为特征的社会经济背景下,特征性野火属性(频率、强度和严重程度)系统性更高,尤其是在意大利南部。野火频率通常较高的情况包括:(i)具有动态社会人口特征的城市周边地区,以及(ii)采用密集耕作制度的农村地区。关于社会经济结构/动态和环境变化的综合信息,对于更好地理解地中海地区野火的地方尺度空间模式至关重要。综合社会环境信息有助于更好地了解当地社区在管理易受野火影响的土地方面的作用,有助于实施更有效的策略,最大限度地减少野火对土地资源的影响。
