The increasing use of new materials\, such as plastics\, h as been one of the most important factors\, as they have allowed for incre ased production in a simpler and more economical way. Various polymer type s are used in different phases of the agricultural production cycle\, but when their use is incorrectly managed\, it can lead to serious environment al impacts. Plastic pollution\, largely perceived by the public as a major risk factor that strongly impacts sea life and preservation\, has an even higher negative impact on terrestrial ecosystems. Indeed\, quantitative d ata about plastic contamination on agricultural soils are progressively em erging in alarming ways. One of the main contributors to this pollution in volves the mismanagement of Agricultural Plastic Waste (APW)\, i.e.\, the residues from plastic material used to improve the productivity of agricul tural crops - such as: greenhouse covers\, mulching films\, irrigation pip es\, etc. Indeed\, a wrong management of agricultural plastics during and after their working lives\, may pollute the agricultural soil and aquifers by releasing macro-\, micro-\, and nano-plastics\, which could also enter into the human food chain. \nIn this study\, an applied and simplified me thodology to quantify and manage agricultural plastics is proposed. The te chniques used are based on a deductive approach\, based on the quantificat ion through the use of different remote-sensed datasets (orthophotos and s atellite images) of the areas covered by plastics used for crop protection . Additionally\, through an inductive approach\, based on statistical data from the agricultural census of the administrative areas of the Italian p rovinces\, an agricultural plastic coefficient (APC) has been proposed\, i mplemented\, and spatialized in a GIS environment\, to produce a database of APW for each type of crop. \nThe study area chosen for the analysis her e presented is a part of the Ionian Coast of Southern Italy\, which includ es the most important municipalities of the Basilicata Region as for fruit and vegetable production. The use of geographical techniques and observat ion methodologies\, developed in an open-source GIS environment\, enabled an accurate location of about 2000 hectares of agricultural land covered b y plastics\, as well as the identification of areas most susceptible to th e accumulation of plastic waste. The proposed methodology can be exported to other countries\, since it represents valuable support that could reali ze\, in integration with other tools\, a database of agricultural plastics use\, which may be a starting point to plan strategies and actions target ed to the reduction of the plastic footprint of agriculture. The technique s and the model implemented\, due to its simplicity of use and reliability \, can be applied by different local authorities\, in order to create an a tlas of agricultural plastics\, which would be applied for their continuou s monitoring\, thereby enabling to upscale future social and ecological im pact assessments\, identification of new policy impacts\, market searches\ , etc. as well.

W ith reference to an area of high environmental\, landscape and archaeologi cal value\, such as the 'Pulo di Molfetta' (Municipality of Molfetta – S outhern Italy)\, some georeferenced floristic surveys have been carried ou t\, with relative mapping and monitoring of the vegetation growth. In this way\, it has been possible to draw up some detailed management measures f or the vegetation\, as well as to plan suitable interventions of ecologica l engineering\, aimed at determining the most appropriate conditions for t he recovery\, use and sustainable management of this study area\, even for tourism purposes. These activities have been conducted through the constr uction of a basic model\, which has been implemented in a Geographical Inf ormation System (GIS)\, structured on the basis of some Free and Open-Sour ce geographic data\, integrated with a geo-localized 3D survey of the geom orphology\, architectural structures and the flora-vegetation habitat. The survey\, georeferencing and 3D model formation operations have been condu cted by means of:\n1) a photogrammetric survey at ultra-low height – var iable\, according to the orography - carried out with Unmanned Aerial Vehi cles (UAVs)\, to obtain a 3D digital modelling\, having a readable resolut ion of at least 2 cm/pixel\;\n2) coverage with a block of frames with nadi ral and sub-horizontal orientation\, for a readability optimized to the an alysis of both the geomorphology and the existing medium and tall vegetati on\;\n3) creation of a framing and support network\, materialized with hig h-contrast photographic targets\, measured with RTK methodologies of GNSS satellite positioning and accuracy ≤ 3 cm\, georeferenced in the RDN2008 Reference Coordinate System - as per Italian regulations\;\n4) restitutio n of a 3D digital model\, obtained with SfM (Structure from Motion) techno logies\, formed by a resolution of 1-2 cm\, point clouds\, triangular mesh and photographic texture\;\n5) formation of a very-high resolution ortho- photomosaic\, with GSD (Ground Sampling Distance) ≤ 15 mm\, and of an ad equate number of radial sections\, with two views\, each one orthogonal to the section plane\;\n6) georeferenced identification of the individual fl oristic-vegetational elements and help for the construction of a database containing the agreed attributes defined and aimed at planning the vegetat ion layers present.\nThe metric analyses have been conducted with commerci al instruments\, such as UAVs systems\, GNSS and photogrammetric processin g software\, in order to test a very widespread\, low-cost operational cha in in the dimensional and qualitative survey of medium-small extensions\, affected by great biodiversity and an important altimetric variation such as a karst sinkhole.\nIn conclusion\, the results thus obtained have allow ed for the inclusion of the geo-localized 3D model in a GIS base for the k nowledge of the flora-vegetation habitat\, thanks to which it will be poss ible to provide support for the decision-making of planning choices for th e territory\, landscape and environment of the study area\, as well as its close surroundings\, so as to safeguard its biodiversity and ecosystem re lations.
