A first analysis on the need to integrate ecological aspects into financial insurance

It is known that financial insurance can address the economic impacts of a natural disaster, but some ecological aspects can play a crucial role in mitigating the overall risks for socio-ecological systems. To better strengthen the study of these relations, the aims of this paper are: (1) to analyze the main research topics of the scientific literature on ecological and/or financial-economic insurance to face natural disasters, through a co-word network analysis; (2) to analyze the temporal trends of the total Gross Insurance Premium and Meteorological and climatological extreme events in 29 OECD countries; and (3) to carry out a Principal Component Analysis (PCA) of some selected variables in order to conceptualize a first empirical model combining financial-economic and ecological insurance to face natural disasters. The literature review has shown a predominance of topics related to financial insurance (about 60%), and the co-word map of key words has highlighted a common space where economic and ecological insurances interact. PCA highlighted three major components explaining 90.6% of the overall variation and discriminating aspects more related to the “financial” insurance, from those related to the “ecological” insurance. More in detail, PC1, which represents the financial insurance, explains the 60.4% of variation, PC2 and PC3 that represent surrogates of the “ecological” insurance explain respectively the 19.6% and the 10.6% of variation. On the basis of the application of the proposed empirical model, countries with high levels of financial and ecological preparedness have been identified. The next steps of this research will be focused on a pilot study area where a quantitative assessment will be applied to better define the landscape contribution to natural disaster risk mitigation, the analysis of the role of social capital through a cross-scales approach, in terms of policies and management strategies, and the investigation of innovative economic tools to take into account specific payment for ecosystem services in the context of natural disasters

The contribution of Utility-Scale Solar Energy to the global climate regulation and its effects on local ecosystem services

One solution to mitigate climate change can be the production of renewable energy. In this context, the aims of this paper are: (1) the identification of local unsuitable areas for the installation of Utility-Scale Solar Energy (USSE) in a municipality in southern Italy; (2) the assessment of the effects of their installation on local natural CO2 sequestration and on avoided CO2; and (3) the evaluation of their contribution to the global climate regulation through scenario analysis. Since 2007, 82 authorizations have been obtained for the installation of USSE in the municipality and 42 over 64 already completed have been installed in unsuitable areas. For what concerns the remaining USSE, two short-term scenarios are analysed in order to take into account their contribution in terms of climate regulation service. The first scenario is called Business As Usual with new planned USSE installed by 2014 also in unsuitable areas, and the second one with the new USSE installed only in suitable areas identified in this study. Surprisingly, Scenario 2 is characterized by a reduced natural capacity to sequester CO2 emissions and by a lower contribution of vegetation in providing the ecosystem service climate regulation in comparison with Scenario 1.

Mapping ecological vulnerability to fire for effective conservation management of natural protected areas.

The challenge for conservation managers is to ensure the long-term sustainability of an area by preserving its ecological and cultural values against predictable and unpredictable natural and human pressures and, at the same time, ensuring the fruition of the environmental resources. This research proposes an integrated use of GIS–based Decision Support System (DSS) with a conceptual linear model of vulnerability to foster conservation strategies in protected areas, by identifying: (1) the most vulnerable areas, requiring specific protection measures to enhance the natural features, as well as the prevention of natural and human risks; (2) the most effective management interventions to reduce system vulnerability to fire. The development of such a tool has been tested on the natural protected area of Torre Guaceto, through the selection of suitable indicators that enable discrimination among different levels of sensitivity and pressures, in order to provide evidence of its potential utility for the management of protected areas and the mitigation of their vulnerabilities. The results highlight that the most vulnerable areas are represented by contiguous patches of wetlands, the load of fuel at wetlands-agricultural lands interface areas, and the small patches of century-old forests, Mediterranean maquis and coastal dunes. On the basis of the results it is desirable that future researches on vulnerability should not only consider the “of what to what”, but also consider “for who, where and when” with a focus on the spatial and temporal scale dimensions of vulnerability

Chemical footprints of anthropogenic nitrogen deposition on recent soil C:N ratios in Europe

Long-term human interactions with landscape and nature produced a plethora of trends and patterns of environmental disturbances in time and space. Nitrogen deposition, closely tracking energy and land use, is known to be among the main pollution drivers, affecting both freshwater as terrestrial ecosystems. We investigated the geographical distribution of nitrogen deposition and the impacts of accumulation on recent soil carbon to nitrogen ratios over Europe. After the Second Industrial Revolution (1880–2010), large landscape stretches characterized by different atmospheric deposition caused either by industrialized areas or by intensive agriculture emerged. Nitrogen deposition affects in a still recognizable way recent soil C:N ratios despite the emission abatement of oxidized and reduced nitrogen during the last two decades. Given the seemingly disparate land-use history, we focused on ~10,000 unmanaged ecosystems, providing evidence for a rapid response of nature to chronic nitrogen supply by atmospheric deposition.JRC.H.5-Land Resources Managemen

Scales, strategies and actions for effective energy planning: A review

none7noThis paper is a review of the most recent literature on the interaction between climate change, land-use and energy, based on the analysis of papers collected through the most relevant scientific literature databases. A total of 114 papers published between 2000 and 2011 were reviewed. The aims of this review are: in general (1) to identify the different research topics that have been developed related to the interaction between climate change, land-use and energy; more specifically, (2) to analyze what are the most suitable spatial and temporal scales of investigation to focus on for actions and strategies to reduce critical issues in the field of energy and environment; (3) to identify which actions and strategies are deemed as the most appropriate to mitigate critical issues in energy and environment; and given the research gaps found in the review, (4) to propose research recommendations in the context of effective climate-energy planning. We argue that there are certain gaps and needs for a ―nested‖ environmental governance. It is necessary to understand how different environmental policies overlap and how they can be integrated in order to verify whether there are conflicting targets that may negate each other in the long term.mixedPasimeni, MARIA RITA; Petrosillo, Irene; Aretano, Roberta; Semeraro, Teodoro; Antonella De Marco, ; Nicola, Zaccarelli; Zurlini, GiovanniPasimeni, MARIA RITA; Petrosillo, Irene; Aretano, Roberta; Semeraro, Teodoro; Antonella De, Marco; Nicola, Zaccarelli; Zurlini, Giovann

New perspectives and approaches in social-ecological landscape evaluation

To face the challenge of sustainable development of human settlements, an effective interdisciplinary integration has to be achieved by embodying the complexities of societies and economies into landscape ecology analyses. Such integration is getting far more complex today as landscape ecology is expanding its scope to respond to the challenges of sustainable development of human–environmental systems. In this paper we point out the recent and novel approaches applied in landscape ecology to move beyond the traditional separation of social and ecological components in social-ecological landscapes (SELs), considering SELs as a whole co-evolving and historically interdependent systems of humans-in-nature. To meet the challenges of sustainability, landscape ecology needs to strengthen its capacity to develop spatially explicit problem solving related to landscape sustainability issues. In this respect, addressing SELs represents a more pragmatic basis for envisioning how the real world works and how we would like the world to be, as SELs represent the spatially explicit integration of social-political and ecological scales in the geographical world. However, there is still the need to go beyond the traditional views embraced by landscape and urban planning where sustainability has been envisioned as a durable, stable condition that, once achieved, could persist for generations

Investigating landscape phase transitions in Mediterranean rangelands by recurrence analysis

Context: Socio-ecological landscapes typically characterized by non-linear dynamics in space and time are difficult to be analyzed using standard quantitative methods, due to multiple processes interacting on different spatial and temporal scales. This poses a challenge to the identification of appropriate approaches for analyzing time series that can evaluate system properties of landscape dynamics in the face of disturbances, such as uncontrolled fires. Objective: The purpose is the application of non-linear methods such as recurrence quantification analysis (RQA) to landscape ecology. The examples concern the time series of burnt and unburnt Mediterranean rangelands, to highlight potential and limits of RQA. Methods: We used RQA together with joint recurrence analysis (JRA) to compare the evolutionary behavior of different land uses. Results: Time series of forests and grasslands in rangelands present both periodic and chaotic components with a rather similar behavior after the fire and clear transitions from less to more regular/predictable dynamics/succession. Results highlight the impacts of fire, the recovery capacity of land covers to pre-burnt levels, and the decay of synchronization towards the previous regime associated with vegetation secondary succession consistent with early successional species. Conclusions: RQA and JRA with their set of indices (recurrence rate: RR, laminarity: LAM, determinism: DET, and divergence: DIV) can represent new sensitive measures that may monitor the adaptive capacity and the resilience of landscapes. However, future applications are needed to standardize the analysis by strengthening the accuracy of this approach in describing the ongoing transformations of natural and man-managed landscapes
