The association of manufacturers of gardening and garden care machinery and equipment announces one of the key themes of the next edition of Eima Green, in November 2020. Meanwhile, a conference on the design and management of green sites of value - carried out in Bari in the context of Agrilevante - anticipates some points of particular interest.
The monumental gardens, the historical residences, the botanical gardens and the parks of the tourist and thermal structures are a cultural heritage but also a great business. To maintain their formidable tourist appeal, these green places require constant maintenance and therefore increasingly efficient and refined mechanization.
This underlines Comagarden - the association that represents the industries producing mechanical tools for gardening and garden care - announcing that the next Eima Green International Exhibition (Bologna, 11-15 November 2020) will have, in addition to the rich display of technologies , a program of meetings and seminars specifically dedicated to the theme of the design and maintenance of "valuable" greenery.
An interesting anticipation of this theme was offered by Comagarden during Agrilevante, which for the first time saw an exhibition section dedicated to green care technologies.
During Agrilevante a workshop was held in fact entitled "The Green Tourism, planning and maintenance" in which Renato Cifarelli took part, as President of Comagarden, Lorenzo Benvenuti of the TESAF of the University of Padua, and Antonio Leone of the University of Salento and of the Polytechnic of Bari.
"The Versailles park has over 7.5 million visitors every year, the Royal Palace of Caserta 940 thousand, the Borromean Islands in Lake Maggiore 700 thousand, the Sigurtà Park on Lake Garda 410 thousand - explained Cifarelli in his introductory address - and many they are all those other tourist sites that have their great attraction in the scenographic trees, in the colorful flowerbeds and in the geometric hedges ".
"But behind the aesthetics of these parks - Cifarelli warns - there is not only taste and creative talent but a set of specialized skills, those botanical, naturalistic, agronomic and to a large extent technological, that is to say concerning the appropriate use of machines and tools, the setting up and setting of the machines, the same design by the manufacturing industries of increasingly innovative and specific vehicles for every type of maintenance, including those related to hanging gardens and "vertical greenery".
In the design of greenery, not only aesthetic but also functional criteria must be applied - pointed out Prof. Benvenuti - because the choice of the essences to be planted changes according to the environmental conditions and the way in which the green is used (the grass can be high or low fruition, depending on how much is subject to trampling, or even to purely aesthetic use, and the same hedges can serve as a shelter, as an acoustic screen, as a scenographic support, etc.) ”.
But first of all, the design of the green area must satisfy the psychological expectations of the public: "the large open lawns evoke the archetype of a lost Eden, and together they give rise to a sense of dominance and prevention of danger - Benvenuti explained - but green space must also include parts of forest or hedges that hide portions of the landscape from view and that can satisfy a need for 'mystery' and 'discovery' that men seem to have in an innate way ”. In addition to improving the aesthetics of the environments and the psycho-physical well-being of people, green spaces are a powerful balancer of territorial systems, especially in urban and peri-urban contexts. "The intensive urbanization carried out in many Italian cities between the 1950s and the 1980s (see the case of Bari, the subject of a specific research project) - explained Prof. Leone - produced the disappearance of green areas and courses of water that would have had the function of absorbing and channeling rainfall, avoiding instability and flooding ”.
"The 'urban voids' must therefore be filled with green essences - added Leone - while the corridors left to nature allow the so-called" soft mobility ", that is to say the transit of people, cyclists and even free animals, performing a function of also requalification of the landscape and biodiversity ". Whatever the development models of the green tourism and recreation - those that require more order and those that instead leave the plants a more spontaneous development - mechanization becomes a decisive tool. Lawnmowers, brush cutters, garden tractors and chainsaws with silent and battery operated engines, but
