The interplay of landscape composition and configuration: new pathways to manage functional biodiversity and agroecosystem services across Europe
2019
Managing agricultural landscapes to support biodiversity and ecosystem services is a key aim of a sustainable agriculture. However, how the spatial arrangement of crop fields and other habitats in landscapes impacts arthropods and their functions is poorly known. Synthesising data from 49 studies (1515 landscapes) across Europe, we examined effects of landscape composition (% habitats) and configuration (edge density) on arthropods in fields and their margins, pest control, pollination and yields. Configuration effects interacted with the proportions of crop and non-crop habitats, and species’ dietary, dispersal and overwintering traits led to contrasting responses to landscape variables. O…
Improving RAMS and WRF mesoscale forecasts over two distinct vegetation covers using an appropriate thermal roughness length parameterization
2019
Land Surface Models (LSM) have shown some difficulties to properly simulate day-time 2-m air and surface skin temperatures. This kind of models are coupled to atmospheric models in mesoscale modelling, such as the Regional Atmospheric Modeling System (RAMS) and the Weather Research and Forecasting (WRF) Model. This model coupling is used within Numerical Weather Prediction Systems (NWP) in order to forecast key physical processes for agricultural meteorology and forestry as well as in ecological modelling. The current study first evaluates the surface energy fluxes and temperatures simulated by these two state-of-the-art NWP models over two distinct vegetated covers, one corresponding to a …

La multifuncionalidad del mundo rural
2002
En este artículo se describen las bases conceptuales de la multifuncionalidad de la agricultura, y se analiza hasta qué punto pueden servir para justificar la intervención pública en apoyo del sector. A continuación, se destacan algunos aspectos concretos que tienen que ver con la multifuncionalidad en las áreas relacionadas con la biodiversidad, el desarrollo rural y la seguridad alimentaria para, finalmente, contemplar las posibilidades que ofrecen las actuales normas de la Organización Mundial del Comercio (OMC) a la hora de tener en cuenta las denominadas «preocupaciones no comerciales» (non-trade concerns) y, entre ellas, las relacionadas con la multifuncionalidad. ereig@uv.es
Modeling Fire Danger in Galicia and Asturias (Spain) from MODIS images
2014
Forest fires are one of the most dangerous natural hazards, especially when they are recurrent. In areas such as Galicia (Spain), forest fires are frequent and devastating. The development of fire risk models becomes a very important prevention task for these regions. Vegetation and moisture indices can be used to monitor vegetation status; however, the different indices may perform differently depending on the vegetation species. Eight different spectral indices were selected to determine the most appropriate index in Galicia. This study was extended to the adjacent region of Asturias. Six years of MODIS (Moderate Resolution Imaging Spectroradiometer) images, together with ground fire data…

Abstract Afforestation aims to recover the vegetation cover, and restore natural ecosystems. The plant species selected for restoration will determine species richness and the fate of the ecosystem. Research focussing on the impact of vegetation recovery on soil quality are abundant, especially on fire affected land and where rehabilitation, afforestation and restoration projects were carried out. However, little is known about how different plants species affect soil erosion and water losses, which are key factors that will impact the fate of the afforested land. Aleppo pine (Pinus halepensis M.) is the species commonly used for afforestation in the Mediterranean and is very successful whe…
Resilienza delle foreste Mediterranee ai cambiamenti climatici - Guida al progetto [Resilience of Mediterranean forests to climate change – Project g…
2017
The overall objective of the project LIFE11+ ENV/IT/000215 RESILFORMED – Resilience of Mediterranean forests to climate change is to preserve the forest systems from the risks due to climate change, through naturalization processes, increased biodiversity and improved responsiveness, in the recovery process, coming from destabilizing events. The specific objective is to implement a regional forest policy able to increase resilience capacity of Sicilian forests, improving their ecosystem capacity and fostering the biodiversity preservation. The project has proposed to pursue five concrete results: 1) drafting guidelines for effective Mediterranean forest management with respect to climate ch…
Analysis, assessment and quantification of the climate changes impact: the resilience silvicultural indicators
2017
Sicilian forests can be considered at high decay risk because of more and more frequent wildfires and, even more, because of climate change effects, like floods, draught, heat waves, snow and wind storms. They are worrying processes, contributing at making ecosystems weaker and intensifying the potential desertification risk in Sicily, one of the most threatened of Italian regions by this form of soil degradation. The most effective approach to mitigate the effects of the climate change has been developed through the following action: analysis, assessment and quantification of the climate change impact: the silvicoltural resilience indicators.
Forest ecosystems in the Monti Sicani Park (Sicily)
2022
The authors analysed the forest ecosystems in the Monti Sicani Park (Sicily). In particular, the state of the natural and non-native forests in the Site of Community Interest (SCI ITA040005) - Monte Cammarata, Contrada Salaci, was evaluated in terms of distribution, evolution of forest dynamics and, silvicultural activities. The evolution of vegetation within two different forest plots are analysed and management strategies are proposed. The finding on Mount Cammarata of seedlings of Fagus sylvatica in the undergrowth of a conifer afforestation is noteworthy.
