Abstract. The rural-urban interface (RUI), known as the area where structures and other human developments meet or intermingle with wildland and rural area, is at present a central focus of wildfire policy and its mapping is crucial for wildfire management. In the Mediterranean Basin, humans cause the vast majority of fires and fire risk is particularly high in the proximity of infrastructure and of rural/wildland areas. RUI's extension changes under the pressure of environmental and anthropogenic factors, such as urban growth, fragmentation of rural areas, deforestation and, more in general, land use/land cover change (LULCC). As with other Mediterranean countries, Portugal has experienced significant LULCC in the last decades in response to migration, rural abandonment, ageing of population and trends associated with the high socioeconomic development. In the present study, we analyzed the LULCC occurring in this country in the 1990-2012 period with the main objective of investigating how these changes affected RUI's evolution. Moreover, we performed a qualitative and quantitative characterization of burnt areas within the RUI in relation to the observed changes. Obtained results disclose important LULCC and reveal their spatial distribution, which is far from uniform within the territory. A significant increase in artificial surfaces was registered near the main metropolitan communities of the northwest, littoral-central and southern regions, whilst the abandonment of agricultural land near the inland urban areas led to an increase in uncultivated semi-natural and forest areas. Within agricultural areas, heterogeneous patches suffered the greatest changes and were the main contributors to the increase in urban areas; moreover, this land cover class, together with forests, was highly affected by wildfires in terms of burnt area. Finally, from this analysis and during the investigated period, it appears that RUI increased in Portugal by more than two-thirds, while the total burnt area decreased by one-third; nevertheless, burnt area within RUI doubled, which emphasizes the significance of RUI monitoring for land and fire managers.

“…Among other applications, such methodology has been applied to explore the impacts of land use on regional water balance and revegetation strategies (Versace et al, 2008); to assess landscape dynamism to be considered in models of LULC change (Lira et al, 2012); to link patterns to processes of LULC changes based on levels of intensity analysis (Huang et al, 2012); and to detect the dynamic linkage between landscape characteristics and water quality evaluating the statistical relationship between landscape metrics and physical-chemical parameters (Huang et al, 2013). It has also been used to provide a set of pressures on biodiversity derived from LULC changes covering a metropolitan area in Chile (Rojas et al, 2013) and for a spatial-temporal land use change analysis in a peri-urban area within the same river basin used as a case study in this paper (Tavares et al, 2012). Yet, as far as we know, it has never been used as a tool to explicitly identify and quantify drivers of environmental change linked both to LULC and LULC change with potential effects on the condition of water bodies.…”

• LULC and LULC changes are important drivers of water condition.• We identified strong signals of systematic transitions.• Consistency and magnitude of systematic transitions reveal processes of LULC change.• Processes of LULC change reveal important drivers of water condition.• Relevant drivers reveal potential pressures linked to the process of transition. Land use and land cover (LULC) are driving forces that potentially exert pressures on water bodies, which are most commonly quantified by simply obtained aggregated data. However, this is insufficient to detect the drivers that arise from the landscape change itself. To achieve this objective one must distinguish between random and systematic transitions and identify the transitions that show strong signals of change, since these will make it possible to identify the transitions that have evolved due to population growth, industrial expansion and/or changes in land management policies. Our goal is to describe a method to characterize driving forces both from LULC and dominant LULC changes, recognizing that the presence of certain LULC classes as well as the processes of transition to other uses are both sources of stress with potential effects on the condition of water bodies. This paper first quantifies the driving forces from LULC and also from processes of LULC change for three nested regions within the Mondego river basin in 1990, 2000 and 2006. It then discusses the implications for the environmental water body condition and management policies. The fingerprint left on the landscape by some of the dominant changes found, such as urbanization and industrial expansion, is, as expected, low due to their proportion in the geographic regions under study, yet their magnitude of change and consistency reveal strong signals of change regarding the pressures acting in the system. Assessing dominant LULC changes is vital for a comprehensive study of driving forces with potential impacts on water condition.

“…Both methods allowed us to determine the landscape changes and to detect pressures acting upon some areas included in the PNA during the last decades (urban and transport infrastructures development, etc). We reviewed i) previous studies focused on photo-interpretation techniques [30][31][32][33][34]; ii) land uses changes and territorial dynamics in different environmental conditions [35][36][37][38][39][40] and iii) definition of land uses categories [41][42][43][44]. We chose two working scales: the first analyzed the variability of the PNA as a whole (1:50,000), and the second, that use a more detail scale, permited us to recognize different ecological processes that occurred in the territory (1:12,500).…”
