Fin dagli inizi della Politica agricola comune (Pac), l'Europa ha cercato di favorire il ricambio generazionale incentivando la presenza di giovani in ambito agricolo. Infatti da sempre la senilizzazione e il mancato turn over sono problemi che affliggono il mondo agricolo. L'articolo analizza gli effetti della misura che finanzia l'insediamento dei giovani agricoltori in Piemonte
Il rapporto, redatto nell'ambito della ricerca dal titolo "Messa a punto di strumenti per la valutazione delle politiche forestali e delle ricadute socio-economiche nel settore forestale piemontese" finanziata dalla Regione Piemonte, completa l'analisi conoscitiva del sistema forestale piemontese attraverso una descrizione delle imprese iscritte all'Albo delle imprese forestali (AIFO). I risultati riguardano l'analisi dei dati contenuti nell'Albo e consentono di descrivere in modo approfondito il settore forestale piemontese, nel tentativo di stimare in modo obiettivo addetti, superfici, volumi lavorati e di fornire indicazioni sul giro d'affari complessivo del comparto. Lo studio dell'Albo riguarda l'insieme delle imprese private del settore forestale, e ne valuta potenzialità e ricadute socio economiche. Si tratta in genere delle imprese che hanno rapporti con la pubblica amministrazione, o che hanno intenzione di intraprenderne: per questa ragione i risultati non descrivono l'intero universo, ma un sottoinsieme piuttosto ridotto. Il rapporto descrive i risultati dell'analisi dei dati e contiene inoltre alcune proposte volte alla definizione di un sistema di raccolta dati più funzionale agli obiettivi gestionali del settore, tali da poter essere utilizzati come strumenti di indirizzo delle politiche.
Knowledge of the distribution and extent of seagrass habitats is currently the basis of management and conservation policies of the coastal zones in most European countries. This basic information is being requested through European directives for the establishment of monitoring programmes and the implementation of specific actions to preserve the marine environment. In addition, this information is crucial for the quantification of the ecological importance usually attributed to seagrass habitats due to, for instance, their involvement in biogeochemical cycles, marine biodiversity and quality of coastal waters or global carbon budgets. The seagrass atlas of Spain represents a huge collective effort performed by 84 authors across 30 Spanish institutions largely involved in the scientific research, management and conservation of seagrass habitats during the last three decades. They have contributed to the availability of the most precise and realistic seagrass maps for each region of the Spanish coast which have been integrated in a GIS to obtain the distribution and area of each seagrass species. Most of this information has independently originated at a regional level by regional governments, universities and public research organisations, which explain the elevated heterogeneity in criteria, scales, methods and objectives of the available information. On this basis, seagrass habitats in Spain occupy a total surface of 1,541,63 km2, 89% of which is concentrated in the Mediterranean regions; the rest is present in sheltered estuarine areas of the Atlantic peninsular regions and in the open coastal waters of the Canary Islands, which represents 50% of the Atlantic meadows. Of this surface, 71.5% corresponds to Posidonia oceanica, 19.5% to Cymodocea nodosa, 3.1% to Zostera noltii (=Nanozostera noltii), 0.3% to Zostera marina and 1.2% to Halophila decipiens. Species distribution maps are presented (including Ruppia spp.), together with maps of the main impacts and pressures that has affected or threatened their ...
A search for dark matter linelike signals iss performed in the vicinity of the Galactic Center by the H.E.S.S. experiment on observational data taken in 2014. An unbinned likelihood analysis iss developed to improve the sensitivity to linelike signals. The upgraded analysis along with newer data extend the energy coverage of the previous measurement down to 100 GeV. The 18 h of data collected with the H.E.S.S. array allow one to rule out at 95% C.L. the presence of a 130 GeV line (at l=-1.5°, b=0° and for a dark matter profile centered at this location) previously reported in Fermi-LAT data. This new analysis overlaps significantly in energy with previous Fermi-LAT and H.E.S.S. RESULTS: No significant excess associated with dark matter annihilations was found in the energy range of 100 GeV to 2 TeV and upper limits on the gamma-ray flux and the velocity weighted annihilation cross section are derived adopting an Einasto dark matter halo profile. Expected limits for present and future large statistics H.E.S.S. observations are also given. ; The support of the Namibian authorities and of the University of Namibia in facilitating the construction and operation of H.E.S.S. is gratefully acknowledged, as is the support by the German Ministry for Education and Research (BMBF), the Max Planck Society, the German Research Foundation (DFG), the French Ministry for Research, the Centre National de la Recherche Scientifique-Institut National de Physique Nucléaire et de Physique des Particules and the Astroparticle Interdisciplinary Programme of the Centre National de la Recherche Scientifique, the United Kingdom Science and Technology Facilities Council (STFC), the Institute of Particle and Nuclear Physics of the Charles University, the Czech Science Foundation, the Polish Ministry of Science and Higher Education, the South African Department of Science and Technology and National Research Foundation, and the University of Namibia. We appreciate the excellent work of the technical support staff in Berlin, Durham, Hamburg, Heidelberg, Palaiseau, Paris, Saclay, and Namibia in the construction and operation of the equipment. R. C.
