    In this paper we use the hybrid integrated model WITCH to quantify and analyze the investments and financial flows stimulated by a climate policy to stabilize Greenhouse Gases concentrations at 550ppm CO2-eq at the end of the century. We focus on investments to decarbonize the power sector and on investments in knowledge creation. We examine the financial flows associated with the carbon market and the implications for the international trade of oil. Criticalities in investment requirements will emerge when coal power plants with carbon capture and sequestration and nuclear power plants are deployed around 2020-2040, both in high and low income regions. Investments in energy related R&D increase sharply and might cause stress in the short term. However, the transition to a low-carbon world, although costly, appears to be manageable from a financial point of view. In particular, R&D financial needs can easily be accommodated using revenues from the carbon market, which is expected to eventually become more important than the oil market in terms of traded value.Climate Change, Mitigation, Carbon Finance, Emission Trading, Energy Investments

    The spectralrao-monitoring Python package : A RAO's Q diversity index-based application for land-cover/land-use change detection in multifunctional agricultural areas

    Get PDF
    Monitoring multifunctional agricultural areas is paramount to ensure their cost-effective management. The remote sensing-based detection of land-cover/land-use (LCLU) changes and analysis of vegetation dynamics constitute a relevant indicator to support robust monitoring schemes, allowing the control of agri-environmental conditions and enforcing related measures and policies. The Rao's Q diversity index (RaoQ) is frequently used to measure functional diversity in ecology, thanks to the textural analysis of the environment. This paper aims to develop and provide an open-source Python application whose workflow may constitute a RaoQ-based LCLU change monitoring tool for multifunctional agricultural areas. Here, a use case is presented for detecting and mapping LCLU changes leveraging the free and open access Landsat 8 (L8) satellite data. The workflow is organized in four main stages: (1) data processing; (2) Normalized Difference Vegetation Index (NDVI) calculation; (3) RaoQ calculation; and (4) detection and mapping of LCLU changes through thresholding of RaoQ. Three methodological approaches were developed (RaoC – “classic” RaoQ; RaoMD – “multidimensional” RaoQ, and “classic + multidimensional” RaoQ) with overall accuracies ranging from 0.88 to 0.92. An example of an agri-environmental monitoring decision-support framework based on spectralrao-monitoring is presented. The application is easily reproducible, and the code is fully available and utilizable with other sensors at different resolutions to support monitoring other types of agricultural areas.During the conception and primary development of this research idea, author A.

    Unmanned Aerial Vehicles for Debris Survey in Coastal Areas: Long-Term Monitoring Programme to Study Spatial and Temporal Accumulation of the Dynamics of Beached Marine Litter

    Get PDF
    Unmanned aerial vehicles (UAVs) are becoming increasingly accessible tools with widespread use as environmental monitoring systems. They can be used for anthropogenic marine debris survey, a recently growing research field. In fact, while the increasing efforts for offshore investigations lead to a considerable collection of data on this type of pollution in the open sea, there is still little knowledge of the materials deposited along the coasts and the mechanism that leads to their accumulation pattern. UAVs can be effective in bridging this gap by increasing the amount of data acquired to study coastal deposits, while also limiting the anthropogenic impact in protected areas. In this study, UAVs have been used to acquire geo-referenced RGB images in a selected zone of a protected marine area (the Migliarino, Massacciuccoli, and San Rossore park near Pisa, Italy), during a long-term (ten months) monitoring programme. A post processing system based on visual interpretation of the images allows the localization and identification of the anthropogenic marine debris within the scanned area, and the estimation of their spatial and temporal distribution in different zones of the beach. These results provide an opportunity to investigate the dynamics of accumulation over time, suggesting that our approach might be appropriate for monitoring and collecting such data in isolated, and especially in protected, areas with significant benefits for different types of stakeholders

    Current and future distribution of a parasite with complex life cycle under global change scenarios: Echinococcus multilocularis in Europe

    Get PDF
    Global change is expected to have complex effects on the distribution and transmission patterns of zoonotic parasites. Modelling habitat suitability for parasites with complex life cycles is essential to further our understanding of how disease systems respond to environmental changes, and to make spatial predictions of their future distributions. However, the limited availability of high quality occurrence data with high spatial resolution often constrains these investigations. Using 449 reliable occurrence records for Echinococcus multilocularis from across Europe published over the last 35 years, we modelled habitat suitability for this parasite, the aetiological agent of alveolar echinococcosis, in order to describe its environmental niche, predict its current and future distribution under three global change scenarios, and quantify the probability of occurrence for each European country. Using a machine learning approach, we developed large-scale (25 × 25 km) species distribution models based on seven sets of predictors, each set representing a distinct biological hypothesis supported by current knowledge of the autecology of the parasite. The best-supported hypothesis included climatic, orographic and land-use/land-cover variables such as the temperature of the coldest quarter, forest cover, urban cover and the precipitation seasonality. Future projections suggested the appearance of highly suitable areas for E. multilocularis towards northern latitudes and in the whole Alpine region under all scenarios, while decreases in habitat suitability were predicted for central Europe. Our spatially explicit predictions of habitat suitability shed light on the complex responses of parasites to ongoing global change

    Marine benthic forms of the Marine Protected Area Capo Caccia-Isola Piana (Sardinia, Italy)

    Get PDF
    The great ecological and economic value of the biocenoses of Marine Protected Area 'Capo Caccia-Isola Piana' (MPA) requires a constant monitoring. For this reason, a continuous study of the area producing overlapping maps useful to control in real time the evolution of the biocenoses is necessary. The integrated use of several methodologies, such as Side Scan Sonar, Remote Operating Vehicle and Drone, has allowed us to realize a very detailed map. This paper presents the marine benthic map of the MPA and compares the present situation with that recorded in 2008

    BACKGROUND Pharmacists contribute to medication safety by providing their services in various settings. However, standardized definitions of the role of pharmacists in hospice and palliative care (HPC) are lacking. AIM The purpose of this scoping review was to provide an overview of the evidence on the role of pharmacists and to map clinical activities in inpatient HPC. METHOD We performed a scoping review according to the PRISMA-ScR extension in CINAHL, Embase, and PubMed. We used the American Society of Hospital Pharmacists (ASHP) Guidelines on the Pharmacist's Role in Palliative and Hospice Care as a framework for standardized categorization of the identified roles and clinical activities. RESULTS After screening 635 records (published after January 1st, 2000), the scoping review yielded 23 publications reporting various pharmacy services in HPC. The articles addressed the five main categories in the following descending order: 'Medication order review and reconciliation', 'Medication counseling, education and training', 'Administrative Roles', 'Direct patient care', and 'Education and scholarship'. A total of 172 entries were mapped to the subcategories that were added to the main categories. CONCLUSION This scoping review identified a variety of pharmacists' roles and clinical activities. The gathered evidence will help to establish and define the role of pharmacists in inpatient hospice and palliative care

    Prescription Trends in Hospice Care: A Longitudinal Retrospective and Descriptive Medication Analysis.

    BACKGROUND In hospice and palliative care, drug therapy is essential for symptom control. However, drug regimens are complex and prone to drug-related problems. Drug regimens must be simplified to improve quality of life and reduce risks associated with drug-related problems, particularly at end-of-life. To support clinical guidance towards a safe and effective drug therapy in hospice care, it is important to understand prescription trends. OBJECTIVES To explore prescription trends and describe changes to drug regimens in inpatient hospice care. DESIGN We performed a retrospective longitudinal and descriptive analysis of prescriptions for regular and as-needed (PRN) medication at three timepoints in deceased patients of one Swiss hospice. SETTING/SUBJECTS Prescription records of all patients ( 18 years) with an inpatient stay of three days and longer (admission and time of death in 2020) were considered eligible for inclusion. RESULTS Prescription records of 58 inpatients (average age 71.7 ± 12.8 [37-95] years) were analyzed. The medication analysis showed that polypharmacy prevalence decreased from 74.1% at admission to 13.8% on the day of death. For regular medication, overall numbers of prescriptions decreased over the patient stay while PRN medication decreased after the first consultation by the attending physician and increased slightly towards death. CONCLUSIONS Prescription records at admission revealed high initial rates of polypharmacy that were reduced steadily until time of death. These findings emphasize the importance of deprescribing at end-of-life and suggest pursuing further research on the contribution of clinical guidance towards optimizing drug therapy and deprescribing in inpatient hospice care

    Calculation and interpretation of fractional green canopy cover in the southwest of Buenos Aires through an open-source mobile application

    Get PDF
    Within the province of Buenos Aires, there is a region known as the semi-arid southwest, integrated by Bahía Blanca, Coronel Rosales, Tornquist, Puan, and Coronel Pringles. In this area, it is possible to find not only bare soil but also soils with dry or alive plant material. It is in the interest of both INTA and the landowners in this area to study soil cover to achieve better decision-making on environmental and productive impact and take advantage of resources in the most efficient way possible. For example, bare soil runs great risks of wind and water, erosion. Through proper analysis and estimation, these problems could be prevented. Our proposal is a mobile application, open-source and freely available, that that speeds up the coverage calculation supports data interpretation and decision-making regarding the coverage and management of soils through photographs taken from mobile devices and synchronized with the cloud. Unlike other existing solutions, our development distinguishes between bare soil, soils covered with alive plant material, and soil covered with dry plant material.EEA BordenaveFil: Jouglard, Juan.

    Assessing the effectiveness of RapidEye multispectral imagery for vegetation mapping in Madeira Island (Portugal)

    Get PDF
    Madeira Island is a biodiversity hotspot due to its high number of endemic/native plant species. In this work we developed and assessed a methodological framework to produce a RapidEye-based vegetation map. Reasonable accuracies were achieved for a 26 categories classification scheme in two different seasons. We tested pixel and object based approaches and the inclusion of a vegetation index band on top of the pre-processed RapidEye bands stack. Object based generally showed to outperform pixel based classification approaches except for linear or highly scattered classes. The addition of a vegetation index to the workflow increased the separability of the Jeffrey-Matusita least separable class pairs, but not necessarily the overall accuracy. The Pontius accuracy assessment highlighted class specific accuracy tradeoffs related to different combinations of the inputs and methods. The approach to be used, in conclusion, should be carefully considered on the basis of the desired result.info:eu-repo/semantics/publishedVersio

    A 73-year-old male with a history of right nephrectomy due to cancer in 1996 was referred to our hospital for dyspnea and acute chest pain. In May 2007, the Shelhigh® No-React® valved bioconduit was implanted using the Bentall-De Bono procedure due to the finding of severe aortic valve insufficiency and acute type A aortic dissection. Nine months after discharge, he was placed on chronic renal dialysis. The patient's condition was followed carefully after being placed on dialysis, and now, thirteen years later the implanted aortic valve is still moving freely without signs of calcification
