“Clonare” le buone pratiche per passare dal dissesto idrogeologico alla gestione responsabile dei bacini idrografici”
The census of 600 volunteers in the file that will be presented tomorrow in Rome
From Basilicata good news: 3 rarest otter spotted and filmed in a pond a few hundred meters from the River Agri (photos and video on the site www.wwf.it)
E 'was a 30 rivers surveyed by WWF, the Agri River in the heart of Basilicata, to give a surprise to a few hours after the event, mostly from the WWF to the Italian rivers: three splendid specimens of the rare otter (Lutra lutra) in intent to eat a pond, have been photographed and filmed by the local officials association. It 'happened in the heart of the Park Appennino Lucano, a great news after the tragic discovery of last year with 4 otters found dead. The new year so lets hope for the species to the biodiversity of that stretch of river, classified among the most 'abused' in the WWF's ranking with 51 illegal waste deposits mapped and 91 between sleepers and dams that interrupt the continuity label. From
map WWF rivers Melfa, Tagliamento, and Angitola Ciane are in good condition best. Followed in mid-table, in descending order, stream Arzino, Taro, Simeto Biferno, Sangro, Piave, Ippari, Magra, Adda, Ofanto, Oreto, Savio. Rounding out the rankings Volturno, Sagittarius-Aterno, Arno, Aniene, Agri, Tiber, Po Primaro and last but not least the Chiascio. This in short, the "picture" that emerges from the dossier WWF "Rivers of Italy" to be presented tomorrow at a conference in Rome at the Palazzo Valentini (Sala Monsignor Di Liegro - Via IV Novembre 119 / a), following the survey last May LIBERAFIUMI which involved over 600 volunteers throughout Italy to map the status of some thirty Italian rivers. The conference, which has the patronage of the Province of Rome, attended by the President, Nicola Zingaretti.
SYNDROME OF ABANDONMENT 'RIVERS FOR ITALIAN
delay political, institutional and cultural diversity in river management, combined with a failure to address endemic in time and responsible environmental problems are perhaps the main cause per comprendere i mali dei nostri fiumi fotografati dal censimento WWF.
Mali come la canalizzazione e la diffusa infrastrutturazione della rete idrografica, il consumo e l’impermeabilizzazione dei suoli, che dovrebbero essere lasciati all’esondazione naturale, la continua distruzione della vegetazione naturale che cresce lungo le sponde, i progetti di navigazione come ultima scusa per cavare sabbia e ghiaia dal letto dei fiumi, l’aumento e la diversificazione degli usi dell’acqua, fino ad usarla in maniera indiscriminata per la neve artificiale.
A questo si aggiunga un devastante incremento dei piccoli impianti idroelettrici, incentivati con i fondi per le energie rinnovabili, soprattutto sull’arco alpino dove you tend not to "lose" a drop of water, to the detriment of instream flow and pace for those who are downstream.
But agriculture, floriculture and animal husbandry produce extremely heavy environmental impacts to watercourses and aquifers in many parts of the country, as the average between the Oglio Po plain, the Po and the Mincio and the plain of 'Arno in Pistoia.
Excessive water withdrawals for different uses, often without coordination between them have distorted the natural regimes of rivers, emphasizing the extremes (floods and low flows) which recently have added the consequences of climate change. In a report just completed by the
European Environment Agency continues, in fact, as between 1998 and 2009 natural disasters caused in Europe a little less than 100 000 deaths, affected 11 million people and resulted in damage to 150 billion euro.
FISH SPEAK ITALIAN 'too' LANGUAGE
In this general situation of vulnerability of aquatic ecosystems in recent years there has been an increase in alien species (species introduced from other parts of the world) of animals and plants that have further contributed impoverish native biodiversity and alter the habitat. The "red list" species of fish Italian shows an alarming situation a bit 'and for all, in particular for the sturgeon, sturgeon and lamprey labdanum river, which in Italy are considered practically extinct. But even seemingly common fish such as eel, dace, tench, pike, rudd and the Latterino few years are considered "quasi-risk" and seem to continue their downward trend from the data collected by the census WWF. Increase of alien species against which, thanks to the increasing vulnerability of river ecosystems and to the unfortunate nuisance, continue to spread is the case dell'Abramide of torpedo, the Pseudorasbora of pond loach Eastern Europe, which were in addition to many already present and "naturalized" as the Persian Sun, largemouth bass, catfish, the Gambusia, pike-perch, carp, rainbow trout and many others. In total the studies identified at least 112 alien species of fauna, including invertebrates and vertebrates, in our country.
THE 'CONSTANT' RIVERS: THE LANDFILL
A section of the dossier is then devoted to illegal dumping of waste found along all the census tracts. Only on the Volturno have been detected 65, while agro (Basilicata) were 51 storage of waste, while 25 on the Sangro (Abruzzo) or 24 Ofanto (Puglia). Of river stretches surveyed by WWF over 12 are affected by the presence of asbestos deposits or, in the river Volturno of the 65 dumps found more than half contained asbestos. To move from the hydrogeological
the responsible management of water catchment areas, WWF has produced some concrete proposals.
renaturation: CONVERT TO 'BOMB' IN healthy and safe environments
the real answer to reducing the damage caused by landslides and flooding more frequent and the renaturation of watercourses to restore the environmental and ecological function of ecosystems, because only a healthy environment can adequately respond to floods, droughts and landslides hydrogeological.
To do this we need to restore water quality, reduce the hydraulic works of exploitation and defense returning space to the river (including through innovative urban relocation and changes), restoring the river geomorphological dynamics (equilibrium in sediment transport, flood and can wander in a diffuse way, restoring a flow regime as close to natural) and ecological corridor (rehabilitation of vegetation in the riparian zone and river corridor ...).
WHERE TO FIND FUNDS:
Beyond a necessary increase in cash from the government, you should be able to use many resources that are already in the area and that, in theory, should be used to cope with the hydrogeological or to encourage the redevelopment of the catchment. The main ones are those stemming from charges for the use of water, which, though often too low, resulting from hydropower production, from the 'agricultural activities, concessions from the extraction of mineral and thermal waters by the concessions of fishing rights, by grants for public water .... Only by an intelligent use of these resources and cootrdinato have sufficient resources for a serious change of course.
5 BEST PRACTICES TO HELP THE RIVERS ALL FROM "Clone"
WWF makes a number of proposals on the basis of a series of experiences and good practices in place including:
REFORESTATION Po near Mantua
The Province of Mantua in 2007, launched the reforestation purposes of ecological and natural areas of public water in the flood plains of the Po, including the response to proposals made after the census of 2001 WWF on the Po. The resources for the 1,000 hectares planted aim of the project are derived largely from "10.0000 hectares of new forests and green systems of multifunctional Lombardy Region. The first priority" Rhodes Island "ended in 2009 with the planting of 60,000 plants of about 50 hectares and the remaining operations are in progress and will include the installation of additional 180,000 plants. And with the request for grant of other areas, the project is continuing, a heritage to bequeath to future generations.
SPACE TO THE RIVER: THE PROJECT SULL'ESINO MARCHE
Esino River Nature Reserve in the WWF Ripa Bianca is often subject to repeated floods affecting mainly agricultural land bordering the River.
The draft of the Reserve, which is one of the most important wetlands in the Marches, to handle the expected flood of turning agricultural land in an area where the river can flow freely finding its natural areas in flood times, thus enhancing the functionality ecological area and reducing the risk to areas downstream.
ENVIRONMENTAL EDUCATION LONG The ANIENE
WWF Lazio in 2005 with the support and collaboration of the Province of Rome, began a program for the enhancement of knowledge and Aniene. The project has produced an environmental education program for understanding the river ecosystem by primary schools and conducting an educational workshop riverside. They were then written two manuals for environmental education, for teachers and students to be promoted in other towns in the valley of media, which contains the most interesting examples of the educational experience conducted by the guys at Subiaco.
EUROPEAN ECO-CERTIFICATION The problem of hydropower
indiscriminate distribution of hydropower can, at least in part, be addressed by a certification that takes into account the river basin as stressed by these activities. CH2OICE the European project, involving the WWF Italy, promotes appropriate criteria for "green dot" hydropower systems that respect as much as possible the integrity of the basin in all its environmental components. It 'been so developed, with the assistance of experts from five European countries (Italy, Slovenia, France, Slovakia and Spain), a certification methodology is technically and economically feasible for the production of hydroelectric power, on the one hand, allowing producers volunteered to check the compatibility of their systems with the good ecological status of watercourses affected the other, allowing the public and end-users to verify the environmental sustainability of energy produced. The official launch at the European level of this certification mark will be 25 February in Rome (www.ch2oice.eu).
CONSERVATION trout NELL'ADDA
A trout conservation program was initiated since 1999 on the river Adda, thanks to the collaboration of the provinces of Lodi, Cremona, Italy with the combination of Spinning Club and other local associations. After collecting data on population e lo stato dell’habitat sono state realizzate azioni per recuperare le uova del pregiato pesce durante le asciutte invernali per farle sviluppare in incubatoi della Provincia e poi reintrodurre gli avanotti nel periodo adeguato . In questo modo èstato possibile salvaguardare un’importante popolazione di questa specie endemica del nord Italia
