This paper aims to investigate the capabilities and limitati ons of the new\nhyperspectral sensor PRISMA (Precursore IperSpettrale dell a Missione Applicativa) by the Italian\nSpace Agency (ASI)\, still little applied to archaeological studies. The PRISMA sensor was tested on\nItalia n terrestrial (Alba Fucens\, Massa D’Albe\, L’Aquila) and marine (Sinu essa\, Mondragone\, Caserta)\narchaeological sites. A comparison between P RISMA hyperspectral imagery and the well-known\nSentinel-2 Multi-Spectral Instrument (MSI) was performed in order to better understand features and\ noutputs useful to investigate the aforementioned areas. At first\, bad ba nds analysis and noise removal\nwere performed\, in order to delete the nu merically corrupted bands. Principal component analysis\n(PCA) was carried out to highlight invisible details in the original image\; then\, spectra l signatures of\nrepresentative areas were extracted and compared to Senti nel-2 data. At last\, a classification analysis\n(ML and SAM) was performe d both on PRISMA and Sentinel-2 imagery. The results showed a full\nagreem ent between Sentinel and PRISMA data\, enhancing the capability of PRISMA in extrapolating\nmore spectral information and providing a better reliabi lity in the extraction of the features.\nthese first analyses\, applied in landscape archaeology studies\, highlight\nthe great spectral operational capabilities of the PRISMA sensor. In future studies\, a great\nadvantage can be brought by performing a reliable pansharpening in order to increas e\nthe resolution of the final images (geometric resolution from pancromat hic and spectral\nresolution from hyperspectral data)\, as well as a more stable multitemporal acquisition in\nthe areas under investigation.

Agro-residues are a large quantity. Their utilization as a sourc e of biomass is a great opportunity in the optic of the spread of the circ ular economy model. Among the agro-residues\, those coming from olive grov es\, vineyard and fruit plantations can be particularly relevant. Biomass residues from agricultural pruning represent a typical case of agro-residu es yearly produced and hardly ever used as a resource for production of en ergy\, biochemical or other products. Mismanagement practices and especial ly burning of those agricultural waste are very common. These cause seriou s human and environmental health problems and threaten food and energy sec urity.\nFor a more sustainable and circular approach in agriculture\, agro -residues\, as those from pruning\, should not be considered as waste\, bu t as a precious resource. To pursue this aim\, there is a need of overcomi ng the technical and logistic problems that farmers experience. A proper m anagement system for biomass from pruning residues is mandatory.\nThis stu dy pretends to contribute to the development of a proper wise collection s ystem for agricultural biomass from pruning. The approach based on a terri torial analysis using a software GIS is followed.\nAt first\, the study in vestigates the types\, production processes and possible optimal sustainab le uses of biomass residues\, highlighting the main issues of the most spr ead practices. Then\, the objective is to map the production of the agricu ltural pruning residues on the territory. The attention is focused on an a rea particularly suited to agriculture in the Apulia Region (Italy). By us ing pruning indices for each crop and the land use map\, the study manages to quantify and localize the pruning residues. Based on this\, the best p osition of the collection centres is defined. The obtained maps can be eas ily used and updated. The study points out the power of the GIS tools for this purpose. The results of this study represent a first important step t owards the improvement of the agro-residues management system and can help policymakers and stakeholders to promote more sustainable actions.
