Reforzamientos poblacionales de Otanthus maritimus (L.) Hoffmanns. & Link (Compositae) en la Comunidad Valenciana (E de España)

2007

Otanthus maritimus (Compositae) es un taxon presente en escasas playas de la Comunidad Valenciana y amenazado por el turismo y urbanismo. A lo largo de varios años se han venido realizando repoblaciones y reforzamientos poblacionales en diversos tramos costeros utilizando diferentes métodos. Asimismo, se han llevado a cabo pruebas de viabilidad de las semillas. El presente artículo ofrece los resultados de unos y otros trabajos. -- Abstract: Otanthus maritimus (Compositae) is a taxon found only in few beaches of the Comunidad Valenciana and is therefore threatened by tourism and urbanism. During the last years, the authors have made seed viability tests as well as dune refforestations and r…

PROGETTO LIFE11 ENV IT 215 RESILFORMED - RESILIENZA AL CAMBIAMENTO CLIMATICO NELLE FORESTE MEDITERRANEE

2013

Le condizioni climatiche delle regioni mediterranee, caratterizzate da frequenti annate siccitose, contribuiscono all’indebolimento degli ecosistemi forestali. Come risultato le foreste riducono le loro capacità produttive e sono più soggette a fenomeni di degrado secondario. Inoltre i contesti economico-sociali possono acuire il degrado con la diffusione di uno scorretto uso della risorsa (tagli boschivi, pascolamento) e con la diffusione degli incendi boschivi. L’obiettivo generale del progetto è preservare i sistemi forestali in ambiente mediterraneo dai rischi derivanti dai cambiamenti climatici, tramite processi di naturalizzazione, aumento di biodiversità e migliorata reattività, nei …

A methodological approach for assessing businness investments in renewable resources from a circular economy perspective

2018

Abstract In this paper, we have analyzed a feasibility project for the realization of a biogas plant at a company in the viticulture sector located in south-central Sicily. Using engineering formulas, we identified the electrical power that the plant could produce using waste products created by the vineyard itself, examined the new and interesting opportunities that have arisen with the encouragement and development of biogas production in Italy, and then assessed the economic feasibility of the investment itself, considering an investment scheme of total capital self-financing. The possibility of using wastes from wine production comes from an in-depth study of the circular economy, that …

Factors explaining being present at work in the forest industry, case–control study

2015

Objectives: The aim of the study was to examine factors explaining few sickness absence hours (=SAH) among forest industry employees. Methods: The source population consisted of 636 forest industry employees in Finland, of which 140 were used as cases (SAH ≤ 1.5% during the past 6.5 years). Controls (140) were randomly selected from the source population (SAH > 1.5%). The study data were collected via a questionnaire. The response rate was 65.4% (mean age 48.5 years, men 67%). Discriminant and log-linear analysis were used to examine the relationships between variables and study groups. Results: Workers are more likely to have few sickness absences when their overall subjective health condi…

Azioni di contenimento dei fenomeni erosivi, di salvaguardia e restauro degli habitat nell’ambito del Progetto LIFE “MACALIFE - Preservation and exte…

2014

In Sicilia, come del resto in gran parte del Mediterraneo, l’impatto millenario delle attività antropiche ha profondamente modificato la struttura e la funzione degli ecosistemi naturali, con evidenti ripercussioni sulla stabilità dei suoli e sull’andamento diffuso dei processi erosivi. L’accresciuta consapevolezza di que-sto rapporto causa-effetto ha posto sempre più in risalto la necessità di mettere in atto adeguati interventi di recupero e di ripristino ambientale, in particolare a favo-re di ecosistemi più esposti e vulnerabili, perlopiù concentrati in corrispondenza delle aree costiere e umide, spesso profondamente trasformati a seguito dell'azione combinata di diversi tipi di disturb…

The use of virtual reality as a potential restorative environment in school during recess

2020

Publisher Copyright: © 2020, Springer Nature Switzerland AG. Copyright: Copyright 2021 Elsevier B.V., All rights reserved. Previous research has found out that simulated, Virtual Reality (VR)-based forests can bring equal or even higher restorative effects than real forests. In this study, a Virtual Reality (VR)-based forest was created in order to compare whether VR-based forest can possess restorative effects in the context of primary school, and how the possible effects compare to restorative effects of a normal recess or to a situation when there is no recess at all. The effects were measured using Restorative Outcome Scale (ROS) and problem-solving tasks after the intervention. The res…

Transition in the Finnish forest-based sector: Company perspectives on the bioeconomy, circular economy and sustainability

2019

The forest-based sector is affected by many profound structural changes and the increasing complexity of the business environment due to, for example, the mature markets of many core products and the aims for bio and circular economies and more sustainable societies. In response to the changing business environment, forest-based sector firms need to restructure their business models and develop new products and services. From the Finnish perspective, new forest-based businesses are crucial in the transition to successful and sustainable bio and circular economies. Views on the concepts of bioeconomy, circular economy and sustainability vary according to which parties are involved. Developin…

Using plot soil loss distribution for soil conservation design

2011

Abstract Soil conservation design is generally based on the estimation of average annual soil loss but it should be developed taking into account storms of a given return period. However, use of frequency analysis in soil erosion studies is relatively limited. In this paper, an investigation on statistical distribution of soil loss measurements was firstly carried out using a relatively high number of simultaneously operating plots of different lengths, λ (11, 22, 33 and 44 m) at the experimental station of Sparacia (southern Italy). Using a simple normalization technique, the analysis showed that the probability distribution of the normalized soil loss is independent of both the scale leng…

Estimating soil loss of given return period by USLE-M-type models

2020

Many field investigations have clearly shown that rare and severe events control total soil erosion occurring over a long time period with up to 92% of total soil erosion over a 7‐year period resulting from just three daily events. Therefore, soil conservation strategies should be developed taking into account large events rather than long‐term average erosion. From an engineering point of view, establishing the soil loss of a given return period is needed. This can be obtained by the frequency analysis of soil loss measurements or by suitable soil erosion models. The USLE‐M modified and USLE‐M based are two empirical Universal Soil Loss Equation‐Modified (USLE‐M) type models which were dev…
