From multiple Ecosystem Services (ES) to ES Multifunctionality: assessing territorial transformations in spatial planning

Urban planning discipline initially arose from the need to rationalize and acquire instruments to manage the expansion of urban agglomerations (Salzano, 1998).Through decade this approach, that we consider as a process, suffered the dualism between urbanism and environmentalism generated a distorted perception of the disciplinary principles. On one side, the radicalization of environmentalism perspective that puts nature conservation before any hypothesis of territorial anthropic transformation deemed necessary to pursue socio-economic development objectives. On the other side, the adoption of human-centered socio-economic development models in which several environmental goods and services spontaneously provided by natural ecosystems were not included in “commodities”, i.e. without exchange value. This second paradigm has only recently - and partially - been questioned. A decisive factor has been the recognition and consequent increase in awareness among scientists, politicians and citizens' movements that natural resources are limited. On the basis of these assumptions, this research work is based on the firm conviction that spatial planning is a privileged dimension in which the above factors can converge in a sustainable perspective. This consideration stimulates research questions oriented to balance the conflicting needs of conservation of natural resources, economic development and social equity. The effective handling of the challenges outlined is undermined by the lack of full integration of the environmental components management in the traditional planning system, which, according to the author, can be ascribed to three main weaknesses: - the first weakness concerns the rigidly prescriptive of “zoning” (Cortinovis & Geneletti, 2020). It is based on verifying the suitability of the territory for a specific function and it leads to an a-priori design of the plan aimed at "conforming" development projects and actions to the pre-established strategy (Janin Rivolin, 2008). This aspect, object of criticism by an extensive scientific literature that puts it in opposition to an alternative approach based on the concept of performance (Baker et al., 2006; Faludi, 2000b; Frew et al., 2016; Geneletti et al., 2017; Haller, 2014), has generated criticalities and inefficiencies (Scorza, Saganeiti, et al., 2020). This lack of flexibility depends from the rapidity with which the community needs evolve, making the traditional plan “vintage” and inadequate (Romano et al., 2018). - an additional weakness of the traditional planning system is the overlapping policies and responsibilities at different territorial government levels (Nolte et al., 2010) that are often reflected in cross-scale political contradictions (Apostolopoulou et al., 2012) linked to a range of sectoral policies (Winkel et al., 2015) and a top-down governance gap (L. C. Stringer & Paavola, 2013). As highlighted by the authors (Scorza et al., 2021; Scorza, Pilogallo, Saganeiti, & Murgante, 2020a), this fragmentation affects long-term strategies related to the sustainable development goals (United Nations, 2015), the mitigation and adaptation measures to climate changes (Lovell & Taylor, 2013; Pachauri et al., 2015; Pramova et al., 2012), the conservation of biodiversity (Balletto et al., 2020; IPBES, 2019) and natural resources (Bongaarts, 2019; Primmer & Furman, 2012). - the third weakness concerns the failure of traditional planning in promoting the quality of territorial transformations beyond minimum thresholds depending on technical and sectorial rules. This criticality manifests itself both at urban scale and at territorial scale. For instance, if we refer to the urban context, the assessment of transformations related to urban development including environmental components pursues, in the Italian practice, the traditional approach related to the concept of "urban standard". These are nothing more than minimum thresholds that regulate the availability of services and facilities for each inhabitant, regardless of the assessment of the effective improvement of citizens' well-being (Colavitti et al., 2020; Graça et al., 2018). In the scientific literature, several authors advocate overcoming this approach, highlighting the opportunity to explicitly refer the real needs of citizens generating specific demands for services and urban functions depending on the specific context (Cortinovis & Geneletti, 2020; Gobattoni et al., 2017; Ronchi et al., 2020). At the territorial scale, the fundamental normative framework for the evaluation of territorial transformations is the Environmental Impact Assessment (EIA). It consists of a coherence check with the binding framework foreseen for the territory in which the project is inserted, and in the consequent agreement/disagreement on the impacts that the project exerts on each component of environmental matrix. The effectiveness of this procedure, already weak in a context where there is no effective process of involvement and participation of decision-makers and stakeholders (R. De Groot, 2006), is further undermined by the absence of adequate monitoring systems of territorial transformations capable of providing a comprehensive and integrated view of the expected effects at several scales (Scorza, Saganeiti, et al., 2020). In spatial planning and land use management, ES constitutes an integrated and robust analytical framework as it is directly related to land use patterns and their changes over time, to the spatial distribution of different spatial components (both natural and anthropic) as well as to the implementation of land use plans and policies (Ronchi, 2018) producing two levels of contributions: informative and methodological. The first refers to the possibility of measuring and spatializing the services that ecosystems provide for citizens' well-being. This implies the possibility to improve the knowledge infrastructure that supports the planning process in its different phases. The spatially explicit assessment of ES can take place ex-ante and provide the elements for deepening the knowledge framework and spatializing the demands emerging from the territory in terms of specific ES (Bolund, Permar & Hunham, 1999). For example, in the urban context it is possible to map areas where there is an unsatisfied demand for recreational services (Giedych et al., 2017; Graça et al., 2018), for local temperature regulation (a service linked to the growing topic of heat islands) (Elliot et al., 2020; Sabrina Lai et al., 2020), or for the absorption of noise and atmospheric pollutants along routes with heavy vehicle traffic (Blum, 2017; De Carvalho & Szlafsztein, 2019). Instead, in the case of ex-post evaluation, ES offer an effective infrastructure for monitoring the actual benefits deriving from the implementation of the planned actions. In addition, we include in this contribution the communicative capacity of this approach towards non-expert stakeholders and decision-makers, which is expressed both by acting as an interface between science and decision-makers (Gustafsson et al., 2020; Perrings et al., 2011), and by contributing to increasing the transparency of the plan process (Karrasch et al., 2014; Schröter et al., 2018). The methodological contribution, instead, refers to support the elaboration and benchmarking of alternative development/transformation scenarios, making quantitatively and spatially explicit the impacts of planned actions on the wider territorial values system (environmental, social, cultural, etc). This reinforces the capacity of rational decision-makers to take “better” decisions (Owens, 2005; Sanderson, 2002; Scorza et al., 2019; Weiss, 1979) by structuring a context-based assessment framework (Gee & Burkhard, 2010; Potschin & Haines-Young, 2013a), tailored to the features of the territorial system’s structure. This dimension becomes even more important when the territorial transformation drivers act in a different scale than the one where impacts become measurable (Scorza, Pilogallo, Saganeiti, Murgante, et al., 2020b). In particular, the focus is on ES multifunctionality intended as the opportunity offered by the ES approach to consider “the joint supply of multiple Ecosystem Services (ES)” (Mastrangelo et al., 2014; Stürck & Verburg, 2017), i.e. the natural capacity of ecosystems to deliver for humans manifold benefits (Hansen & Pauleit, 2014). This concept derives from disciplinary fields related to ecology (Byrnes et al., 2014). It was successively adopted in conservation planning where, for the purposes of biodiversity conservation and enhancement, was applied as a criteria to define priority areas to be protected (Cimon-Morin & Poulin, 2018; García-Llorente et al., 2018; Y.-P. P. Lin et al., 2017; Vaz et al., 2021). In contrast to monofunctional “grey” infrastructures, the European Commission furtherly declined its meaning within the “Green Infrastructure-Enhancing Europe’s Natural Capital” Strategy (European Environment Agency, 2013) where GI are defined and specifically designed to “deliver a wide range of ES”. In this specific application domain, ES multifunctionality has been applied at different spatial scales from the urban to the territorial one (Arcidiacono et al., 2016; Cannas et al., 2018b; D. La Rosa & Privitera, 2013; Sabrina Lai et al., 2018a; Ronchi et al., 2020; Zhang & Muñoz Ramírez, 2019). Whereas initially it constitutes a value in itself (from the perspective of providing as many of whatever ES as possible), aiming at meeting as many demands and valuing co-benefits as much as possible (Hansen & Pauleit, 2014). Recently, the interest in spatial and urban planning disciplines toward the ES multifunctionality approach also increased (Artmann, 2014; Dendoncker et al., 2013; Hansen et al., 2015; Primmer & Furman, 2012). This is due to several factors. Firstly, some authors point it as a useful tool to operationalize the concepts of efficient use of natural resources’ use efficiency (Gómez-Baggethun & Barton, 2013a) and sustainability (R. De Groot, 2006; Dendoncker et al., 2013; Selman, 2009), included among the founding principles of planning (Las Casas & Scorza, 2016a). Secondly, considering several goods and benefits simultaneously, means pursuing several environmental, social, cultural and economic objectives and addressing different potentially conflicting demands in both urban planning and spatial governance. This directly relates to the complexity of socio-ecological systems (Gómez-Baggethun & Barton, 2013b; Murray-Rust et al., 2011) that characterize human settlements: the capacity to supply multiple ES results in perceived benefits, for example in terms of human health, social cohesion and in the diversification of rural economic opportunities (Fagerholm et al., 2020; Lafortezza et al., 2013; Tzoulas et al., 2007). Finally, different authors (Galler et al., 2016a; Uthes et al., 2010) argue that pursuing ES multifunctionality as an objective, makes it possible to increase the efficiency of efforts - including economic ones - to protect the various environmental components. Although there is no unambiguous definition of ES multifunctionality in the literature (Mastrangelo et al., 2014) and there is also a lack of agreement on which ES should be delivered by territorial components in order to be considered “multifunctional” (Stürck & Verburg, 2017), this approach promises to be able to confer several added values to the plan process. In the light of these premises, the research program was structured around one main question: How can the ES multifunctionality approach contribute to renew the planning system placing environmental components as services providers whose availability represents a pre-condition for any sustainable development strategy? Therefore, the general objective is to deepen the ES multifunctionality concept, generalizing a framework methodology supporting the planning process. The research was therefore divided into several steps. An extensive analysis of scientific bibliography was carried out in order to explore conceptualizations, computational methods and applications of ES multifunctionality to selected case studies in order to demonstrate potentials and shortcomings. The thesis structure follows the “three papers” format, which generally consists of a collection of articles recently published in (or submitted for publication to) international peer-review journals. Specifically, this thesis consists of an introductory chapter that places the research agenda within the broader disciplinary framework, five chapters that constitute the main body of the thesis and a final chapter that describes the major findings and outlines the future perspectives of the research. The main contents of each chapter are described below: - Chapter 2 proposes a critical review of the ES multifunctionality in the urban and spatial planners’ perspective; - Chapter 3 has the purpose of illustrating the main computation methods of the ES subsequently implemented in the further case studies; - Chapter 4 describes an original “Cities ranking” applying ES multifunctionality approach based on the Multiple Ecosystem Services Landscape Index (MESLI) formulated by (Rodríguez-Loinaz et al., 2015b). - Chapter 5 is a further application of the ES multifunctionality approach conducted at the national scale. With the purpose is to provide an interpretive framework of the land use dynamics that occurred in the period 2000-2018 based on three different indices of ES multifunctionality. The results show that the settlement dynamics and the territorial transformations occurred, produced a different effect on the three indices highlighting that their joint interpretation can support the definition of ES multifunctionality conservation strategies. The last concluding chapter illustrates the results highlighting that they may contribute to reinforce the planner’s toolkit for a more effective decision-making in managing territorial development (Batty, 2013; Friedmann, 2019; Healey, 2003), defining an up to date methodological framework oriented to enhance the procedural approach in planning (Alexander & Faludi, 2016), grounded on evaluation stage (Weiss, 1972) highlighting lessons learnt and cyclic approach

Integrated Environmental Study for Beach Management: A Methodological Approach

This paper aims to present a project convened by the University of Genoa and Fondazione Eni Enrico Mattei (FEEM), in collaboration with Local Authorities, concerning the development of tools for beach management in the Riviera del Beigua (Liguria Region, Italy). The aim of the first step of the project is to assess the environmental state of resort beaches examining them interdisciplinary, through a data analysis based on a sound understanding of the components of the physical and the human system. The following step will be the treatment of the data, through the use of various instruments, which use a synthesis analysis, such as the traditional SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis, and the use of a set of environmental and socio-economic indicators. Finally, our ultimate target is to propose guidelines, which will supply an instrument to back up policies concerning beach planning and management.Costal management, Sustainable tourist, Integrated assessment, Indicators

Integrated Indicators for the Estimation of Vulnerability to Land Degradation

In this chapter we approach the assessment of the vulnerability to land degradation of a typical Mediterranean environment using a modified version of the ESA model. This approach combines analyses of the socio-economic component with analyses of the vegetation trends. According to the standard ESA strategy, different indicators representing the impact of agricultural and grazing activities are used. The main feature of these indicators is that they are census-based and consequently suitable only for the analysis at municipal scale. Therefore we have also elaborated a mechanization index (proxy for soil compaction induced by agricultural machineries) that uses land cover and morphological data [36], enabling high spatial resolution and faster rate of update. The indicators related to the anthropic impact are integrated into an overall Land Management Index (LMI) and in each area it is possible to enhance the main contributing factors to highlight the prevailing forces that drive human-induced degradation processes. In order to include vegetation in the vulnerability map we analyze satellite vegetation index NDVI (Normalized Difference Vegetation Index) which is recognized as ideal tool for monitoring long term trends of degradation phenomena and assessing different values of severity of the concerned processes [37,38]. The final result of our analyses is an integrated vulnerability map of the investigated region, accounting for management and vegetation factors, which allows us to identify priority sites where restoration/rehabilitation interventions are urgent. The adopted procedure can be easily applied to geographic contexts characterized by high complexity in terms of land cover type and economic vocation (intensive agriculture, grazing, industrial activities) thus enabling an early detection of the areas most vulnerable to land degradation

Modeling Spatio-Temporal Divergence in Land Vulnerability to Desertification with Local Regressions

Taken as a classical issue in applied economics, the notion of ‘convergence’ is based on the concept of path dependence, i.e., from the previous trajectory undertaken by the system during its recent history. Going beyond social science, a ‘convergence’ perspective has been more recently adopted in environmental studies. Spatial convergence in non-linear processes, such as desertification risk, is a meaningful notion since desertification represents a (possibly unsustainable) development trajectory of socio-ecological systems towards land degradation on a regional or local scale. In this study, we test—in line with the classical convergence approach—long-term equilibrium conditions in the evolution of desertification processes in Italy, a European country with significant socioeconomic and environmental disparities. Assuming a path-dependent development of desertification risk in Italy, we provided a diachronic analysis of the Environmental Sensitive Area Index (ESAI), estimated at a disaggregated spatial resolution at three times (1960s, 1990s, and 2010s) in the recent history of Italy, using a spatially explicit approach based on geographically weighted regressions (GWRs). The results of local regressions show a significant path dependence in the first time interval (1960–1990). A less significant evidence for path-dependence was observed for the second period (1990–2010); in both cases, the models’ goodness-of-fit (global adjusted R2) was satisfactory. A strong polarization along the latitudinal gradient characterized the first observation period: Southern Italian land experienced worse conditions (e.g., climate aridity, urbanization) and the level of land vulnerability in Northern Italy remained quite stable, alimenting the traditional divergence in desertification risk characteristic of the country. The empirical analysis delineated a more complex picture for the second period. Convergence (leading to stability, or even improvement, of desertification risk) in some areas of Southern Italy, and a more evident divergence (leading to worse environmental conditions because of urban sprawl and crop intensification) in some of the land of Northern Italy, were observed, leading to an undesired spatial homogenization toward higher vulnerability levels. Finally, this work suggests the importance of spatially explicit approaches providing relevant information to design more effective policy strategies. In the case of land vulnerability to degradation in Italy, local regression models oriented toward a ‘convergence’ perspective, may be adopted to uncover the genesis of desertification hotspots at both the regional and local scale

CONTRIBUTION OF PROTECTED AREAS TO AVOIDED DEFORESTATION IN MATO GROSSO, BRAZIL

Protected Areas (PAs) are important spaces for the protection of biodiversity, capable of halting deforestation and collaborating in the intentions to reduce climate change. The objective of this work is to demonstrate the importance of Protected Areas in the state of Mato Grosso in the avoided deforestation and to estimate their contribution to the reduction of greenhouse gas emissions and soil erosion. The methodology was based on secondary data and the use of a GIS environment. As a result, it was found that in Mato Grosso there are 120 PAs between federal, state and municipal, they protect 6% of the territorial area of the state and most are located in the Amazon biome. Mato Grosso’s Forest cover in 2019 was 49.8 million hectares, with an estimated forest carbon stock of over 16.4 GtCO2. The PAs were created over the years in the state, but the greatest number occurred between 2000 and 2005 and together, in 2019 they were responsible for preventing the deforestation of more than 726,000 hectares of forest, 10 million tons of erosion and storing 281 million tons of carbon, which if traded on the credit market would have an estimated value of more than US$1.25 million. If the PAs did not exist and if deforestation were to be carried out, the cost of replacing this area would be more than US$2.73 billion. Therefore, the importance of PAs in environmental conservation and in the economy related to forest cover is notorious

SPATIAL ANALYSES AND REMOTE SENSING FOR LAND COVER CHANGE DYNAMICS: ASSESSING IN A SPATIAL PLANNING

ABSTRACT (EN) Spatial planning is a crucial discipline for the identification and implementation of sustainable development strategies that take into account the environmental impacts on the soil. In recent years, the significant development of technology, like remote sensing and GIS software, has significantly increased the understanding of environmental components, highlighting their peculiarities and criticalities. Geographically referenced information on environmental and socio-economic components represents a fundamental database for identifying and monitoring vulnerable areas, also distinguishing different levels of vulnerability. This is even more relevant considering the increasingly significant impact of land transformation processes, consisting of rapid and frequent changes in land use patterns. In order to achieve some of the Sustainable Development Goals of the 2030 Agenda, the role of environmental planning is crucial in addressing spatial problems, such as agricultural land abandonment and land take, which cause negative impacts on ecosystems. Remote sensing, and in general all Earth Observation techniques, play a key role in achieving SDG 11.3 and 15.3 of Agenda 2030. Through a series of applications and investigations in different areas of Basilicata, it has been demonstrated how the extensive use of remote sensing and spatial analysis in a GIS environment provide a substantial contribution to the results of the SDGs, enabling an informed decisionmaking process and enabling monitoring of the results expected, ensuring data reliability and directly contributing to the calculation of SDG objectives and indicators by facilitating local administrations approaches to work in different development and sustainability sectors. In this thesis have been analyse the dynamics of land transformation in terms of land take and soil erosion in sample areas of the Basilicata Region, which represents an interesting case example for the study of land use land cover change (LULCC). The socio-demographic evolutionary trends and the study of marginality and territorial fragility are fundamental aspects in the context of territorial planning, since they are important drivers of the LULCC and territorial transformation processes. In fact, in Basilicata, settlement dynamics over the years have occurred in an uncontrolled and unregulated manner, leading to a constant consumption of land not accompanied by adequate demographic and economic growth. To better understand the evolution and dynamics of the LULCCs and provide useful tools for formulating territorial planning policies and strategies aimed at a sustainable use of the territory, the socio-economic aspects of the Region were investigated. A first phase involved the creation of a database and the study and identification of essential services in the area as a fundamental parameter against which to evaluate the quality of life in a specific area. The supply of essential services can be understood as an assessment of the lack of minimum requirements with reference to the urban functions exercised by each territorial unit. From a territorial point of view, the level of peripherality of the territories with respect to the network of urban centres profoundly influences the quality of life of citizens and the level of social inclusion. In these, the presence of essential services can act as an attractor capable of generating discrete catchment areas. The purpose of this first part of the work was above all to create a dataset of data useful for the calculation of various socio-economic indicators, in order to frame the demographic evolution and the evolution of the stock of public and private services. The first methodological approach was to reconstruct the offer of essential services through the use of open data in a GIS environment and subsequently estimate the peripherality of each municipality by estimating the accessibility to essential services. The study envisaged the use of territorial analysis techniques aimed at describing the distribution of essential services on the regional territory. It is essential to understand the role of demographic dynamics as a driver of urban land use change such as, for example, the increase in demand for artificial surfaces that occurs locally. Social and economic analyses are important in the spatial planning process. Comparison of socio-economic analyses with land use and land cover change can highlight the need to modify existing policies or implement new ones. A particular land use can degrade and thereby destroy other land resources. If the economic analysis shows that the use is beneficial from the point of view of the land user, it is likely to continue, regardless of whether the process is environmentally friendly. It is important to understand and investigate which drivers have been and will be in the future the most decisive in these dynamics that intrinsically contribute to land take, agricultural abandonment and the consequent processes of land degradation and to define policies or thresholds to mitigate and monitor the effects of these processes. Subsequently, the issues of land take and abandonment of agricultural land were analysed by applying models and techniques of remote sensing, GIS and territorial analysis for the identification and monitoring of abandoned agricultural areas and sealed areas. The classic remote sensing methods have also been integrated by some geostatistical analyses which have provided more information on the investigated phenomenon. The aim was the creation of a quick methodology that would allow to describe the monitoring and analysis activities of the development trends of soil consumption and the monitoring and identification of degraded areas. The first methodology proposed allowed the automatic and rapid detection of detailed LULCC and Land Take maps with an overall accuracy of more than 90%, reducing costs and processing times. The identification of abandoned agricultural areas in degradation is among the most complicated LULCC and Land Degradation processes to identify and monitor as it is driven by a multiplicity of anthropic and natural factors. The model used to estimate soil erosion as a degradation phenomenon is the Revised Universal Soil Loss Equation (RUSLE). To identify potentially degraded areas, two factors of the RUSLE have been correlated: Factor C which describes the vegetation cover of the soil and Factor A which represents the amount of potential soil erosion. Through statistical correlation analysis with the RUSLE factors, on the basis of the deviations from the average RUSLE values and mapping of the areas of vegetation degradation, relating to arable land, through statistical correlation with the vegetation factor C, the areas were identified and mapped that are susceptible to soil degradation. The results obtained allowed the creation of a database and a map of the degraded areas to be paid attention to

Monitoring and modeling urban sprinkling: a new perspective of land take

According to the studies done until now on the recent urban transformation dynamics, namely urban sprinkling, this thesis aims to investigate the phenomenon from different points of view to bring out its unsustainable character. The urban dispersion phenomena, specific characteristic of low-density territories, will be examined through the sprinkling index by including new components in addition to the traditional settlement system components. It allows to evaluate the shape of the anthropic settlements and the distance between them which often results in fragmentation of the urban settlements which in turn generate landscape fragmentation. Nowadays, both in the proximity of large cities and in more external areas such as rural areas, there are often evidences of strong fragmentation of the anthropic settlements in which, even if the amount of occupied surface (land take) may not seem worrying, its configuration determines a general decrease in ecological connectivity, landscape quality and general degradation of soil functions. The general hypothesis is that fragmentation (of urban, landscape and habitat) can become an indicator of land take. In fact, it is not enough to consider only the loss of natural or agricultural areas, but also the distribution of buildings in the landscape matrix, i.e., its spatial component. An emblematic case is that of Basilicata region whose dynamics of transformation from the 50s to the present day will be investigated in this thesis. According to the latest report of the Italian Institute for Environmental Protection and Research (ISPRA 2020), the Basilicata region has only 3.15% of land consumption compared to the entire regional surface. This indicator is in contrast with the shape of the anthropic settlements which results fragmented and dispersed. It is essential that the effects of fragmentation as well as ecosystem disaggregation take on a "measurable" character, joining the list of indicators of urban and territorial quality such as land take and land consumption that European Union addresses to national communities currently consider essential and decisive to highlighting the efficiency/inefficiency of environmental and landscape management. It is crucial to understand and investigate what have been and will be in the future the most influential drivers on these dynamics that contribute intrinsically to land consumption and to define the addresses or the thresholds to contain this pulverized and disordered dissemination of anthropic settlements

Landscape Ecology

This book has been written to present major and efficient applications in landscape ecology, as well as to propose a solid action for this category of topics. The book aims to illustrate various treatment methods of the land-use models impact on landscape ecology creation. The book is divided into three parts: Part I: Ecological interpretation of land-use act - in this part, ecosystem and land use turn out to be a significant factor in the process of creating an ecological landscape. Part II: Landscape district in applied ecological analysis - this part attempts to illustrate the best possible model of analysis integrated with landscape in practical case studies. Part III: The anthropogenic impacts on landscape creation - this part discusses the human impact on landscape creation

Micro-topography associated to forest edges

Forest edges are often defined as the discontinuity between the forest habitat and an adjacent open habitat, thus they are based on a clear difference in the structure of the dominant vegetation. However, beside this very general definition, in the field we can observe a large diversity of edges, with often different kinds of micro-topography features: bank, ditch, stone wall, path, etc. As these elements are rather common in many temperate forest edges, it seems important to start to characterize them more clearly and with consistency. From a set of observations in south-western France, we build a first typology of the micro-topographic elements associated to forest edges. For each of them we describe the process, natural or human induced, at their origin, and according to the literature available, we identify some of their key ecological roles. Banks, generated by the differential erosion between forest and crops along slopes, are especially analyzed since they are the most common micro-topographic element in our region. It offers many micro-habitat conditions in the soil used by a wide range of species, notably by several bee species. More research is required to study in details the importance of such micro-topographic elements

Bridging the Gap

The concept of resilience has arisen as a “new way of thinking”, becoming a response to both the causes and effects of ongoing global challenges. As it strongly stresses cities’ transformative potential, resilience’s final purpose is to prevent and manage unforeseen events and improve communities’ environmental and social quality. Although the resilience theory has been investigated in depth, several methodological challenges remain, mainly related to the concept’s practical sphere. As a matter of fact, resilience is commonly criticised for being too ambiguous and empty of meaning. At the same time, turning resilience into practice is not easy to do. This will arguably be one of the most impactful global issues for future research on resilience. The Special Issue “Bridging the Gap: The Measure of Urban Resilience” falls under this heading, and it seeks to synthesise state-of-the-art knowledge of theories and practices on measuring resilience. The Special Issue collected 11 papers that address the following questions: “What are the theoretical perspectives of measuring urban resilience? What are the existing methods for measuring urban resilience? What are the main features that a technique for measuring urban resilience needs to have? What is the role of measuring urban resilience in operationalising cities’ ability to adapt, recover and benefit from shocks?
