“…Other methods aim to assess fragmentation by identifying the state of habitats on different patches of the landscape [45]. They consider local roads and railways with a friction coefficient value equal to zero and for high-speed roads and railways a value equal to 16 (dimensionless number) [46]. In this way, no weight is given to local roads such as those analyzed in this study.…”

In many countries in the world, the conservation of habitats is at risk mainly due to anthropic pressures on the environment. A study was conducted to assess the extent to which sensitive and high nature-value habitats are damaged by high-impact human activities. Some evaluation methods that are applied may not be entirely appropriate to the characteristics of the investigated areas or may be very accurate but provide results that are delayed with respect to the occurrence of the events that created the loss of their characteristics. The main purpose of this study is to optimise some methodologies for monitoring the impacts of human activities making it possible to obtain better results in less time and with much lower costs. This methodology has been applied in two different areas present in the Puglia Region in south-eastern Italy, in the central Mediterranean area. The biotope fragmentation method was applied on coastal dunes, in the province of Brindisi, affected by an important tourist influx. The results of the inclusion, in the evaluation methodology, of the remote sensing of the paths indicate a more real situation on the state of fragmentation of the coastal dunes. The second methodology concerns the monitoring, through topographical profiles obtained from Sentinel-1 DEM images, of active and inactive mining sites, allowing to obtain of very detailed information on the progress of mining activities in a very short time. By implementing these methodologies, it is possible to improve the control of the territory allowing a more detailed analysis in order to safeguard the environment from impacting human activities and avoiding, as much as possible, the occurrence of illegal activities. Finally, compensation factors to ensure that human activities are conducted in a sustainable way are also evaluated.

“…Working with functional aspects of connectivity involves using species-specific data, which are difficult to obtain at a national level (Scolozzi & Geneletti, 2012;Smith, 2012). Finally, it is also noteworthy that although both these indicators are valid at a national level (Mancebo Quintana et al, 2010;Ortega et al, 2012;Monzón et al, 2013), the data and GIS methods used differ substantially: accessibility results are obtained by points in the centroids of cities, while connectivity is calculated by pixel, which complicates the map-based representation of both effects simultaneously.…”

“…The structural connectivity indicator selected was proposed by Mancebo Quintana et al, (2010), and has proven its usefulness in landscape and infrastructure planning in several studies (Mancebo Quintana et al, 2010;Ortega et al, 2016;De Montis et al, 2017). It assigns a value for scenario 𝑆 𝑘 to each pixel i in the study zone, and measures the area corresponding to the same type of natural habitat as in the cell in question, divided by the effective distance between the pixel and the analogous habitat.…”

“…Network effects measure the contribution of a particular infrastructure improvement or impact to the transport network as a whole (López et al 2009). These impacts can be understood as the consequences of the development interacting with the impacts of other developments, and include changes to biodiversity (environment) and accessibility (socio-economic impact), which must be considered in terms of the effects on the network (López et al 2009;Mancebo Quintana et al 2010). Correct approaches are crucial to ensure the sustainability of the project when studying the alternatives.…”

The EIA procedure should predict and identify the major impacts of a project development that may cause specific spatial and temporal effects. Early in the EIA, the scoping stage provides all the relevant information on the impacts of the project alternatives. In particular, potential effects on the territorial network such as habitat connectivity loss and accessibility improvements should be taken into account in the various proposed layout alternatives when evaluating transport infrastructure projects. However several authors have identified deficiencies in practice. The aim of this article is to provide a methodology for the assessment of these territorial impacts using adequate indicators in the early stages of the EIA procedure.The proposed method is based on a comparison of a range of alternative layouts for a railway line linking two population centres, using indicators calculated with Geographic Information Systems (GIS). The methodology was applied to a case study -the rail link between Huelva (Spain) and Faro (Portugal)-, and the HSR and conventional rail were evaluated in different layouts. The method was effective in spatially identifying significant impacts on accessibility improvements, which occurred closer to the crossborder area. The conventional railway alternatives have similar accessibility values to the HSR. The results also reveal that connectivity loss is not limited to the area around the infrastructure, but extends throughout the territory. The results are at variance with the initiative proposed by Spanish and Portuguese transport decision-makers, and raise the possibility of selecting a conventional railway option. An adequate territorial evaluation methodology enables the new action to be correctly assessed, and supplies the information required to propose the most suitable alternative from a socio-economic and environmental standpoint, regardless of whether this proposal was initially included in the transport policy.
