A WebGis tool called GoProsit has been developed to support winegrowers in planning a new sustainable vineyard and in the identification of high-quality terroir in Tuscany, Central Italy, by providing various information on soils, climate, hydrological risks, and fertilization. GoProsit, hosted by the web platform GEAPP, is a free, user-friendly, and interactive Geographic Decision Support System (GDSS). Soil data behind the WebGis tool has a 1 ha resolution, achieved by processing the legacy vector-type soil database of the Tuscany Region with the DSMART (Disaggregation and Harmonization of Soil Map Units Through Resampled Classification Trees as supervised classification) algorithm, which disaggregated the map to 297,023 vineyard grid cells. Each grid cell holds climatic and pedologic information, along with physical and chemical features for each horizon of the most probable soil. GoProsit also provides soil maps in image format obtained by georeferencing about 50 historical soil maps (1969–2012). Finally, GoProsit runs and returns the outputs of six models: (a) carbon footprint, (b) potential erosion and maximum vine row length compatible with tolerable erosion, (c) potential water stress, (d) risk of runoff/waterlogging, (e) identification of suitable rootstocks, and (f) nutritional needs before planting. Statistics of the main model results for the investigated area are reported. This promising tool will soon be usable for the whole Italian territory; however, its potential makes it suitable for use in any wine-growing district. [ABSTRACT FROM AUTHOR]

Ecosystems in rural areas play a crucial role in promoting human well-being and economic development by providing essential resources such as food, water, raw materials, and energy. Furthermore, rural ecosystems offer various services, such as recreational opportunities, climate regulation, biodiversity conservation, and environmental mitigation. However, a narrow focus on provisioning services has led to the standardisation of landscapes, decreased levels of biodiversity and reduced ecosystem services in several areas. Moreover, diverse rural landscapes can enrich the provisioning, regulating, cultural, and supporting services. While much research has explored the relationship between land use, landscape, and ecosystem services, there is still a need to better understand the trade-offs and synergies between these factors in providing ecosystem services. To address this gap, we conducted an empirical analysis of the perception of ecosystem services provided by different rural landscapes in the Tuscany region. Specifically, we used the concept of morphotypes, which describes 'invariants' that distinguish six different rural landscape typologies in the region. We surveyed 28 experts to identify rural landscape contributions to 17 ecosystem services. Our results provide empirical evidence and insight into the mechanisms necessary to align the provision of ecosystem services by rural landscapes with current and future needs.

Plants have always been used by people for multiple purposes, but over the centuries knowledge of useful plants has largely been lost. Through ethnobotanical studies it is possible to retrieve information on the uses of plants and renew the ancient attention to plants which could be useful to apply in modern applications. In this context, the ethnobotanical use of halophytes has not been explored in depth. The present study focused on the flora of two brackish areas of the north-western Mediterranean sited in Tuscany, Italy. This research aimed to identify the halophyte species of ethnobotanical interest and create a relative map database of the study areas. The floristic list of the two areas, including 78 halophyte and non-halophyte species, was created following periodic field sampling, localization of the species by GPS, and taxonomic identification. The ethnobotanical information was acquired through a bibliographic survey. Botanical, geographic, and ethnobotanical information was filed and included in floristic maps produced using the free Open Source QGIS software. Of the total wild species surveyed, 50% were halophytes with ethnobotanical properties, with a predominance for medicinal ones. Some of them are the subject of numerous studies today such as those on antioxidants. Both investigated areas showed a high floristic and ethnobotanical value. This makes them interesting as potential germplasm banks to be used in various application contexts of ethnobotany. [ABSTRACT FROM AUTHOR]

Nowadays the heightened awareness of the critical trend in resource depletion impels to improve the eco − sustainability of any productive process. The research presented in this paper aims to quantify the environmental impact of the emerging productive process of edible flowers, focusing on two model species, i.e., Begonia x semperflorens − cultorum hort and Viola cornuta L., and two types of product, i.e., flowering potted plants sold in plastic vases and packaged flowers ready to be consumed. The study was carried out in an Italian nursery located in Tuscany, interviewing the owners in order to complete the Life Cycle Inventory, assessing the value of the impact categories, and using the "cradle to gate" approach. The information about the production of flowering potted plants and packaged flowers were inserted in a database and elaborated by the appropriate software. The results of the Life Cycle Assessment (LCA) analysis referred to 1 g of fresh edible flowers and were expressed in four impact categories. Global Warming Potential (GWP) values ranged from 24.94 to 31.25 g CO2 eq/g flowers, Acidification Potential (AP) ranged from 8.169E − 02 to 1.249E − 01 g SO2 eq/g flowers, Eutrophication Potential (EP) ranged from 3.961E − 02 to 5.284E − 02 g PO43 − eq/g flowers, and Photochemical Ozone Creation Potential (POCP) ranged from 8.998E − 03 to 1.134E − 02 g C2H4 eq/g flowers. Begonias showed lower emissions than violas in the GWP and POCP indexes, whereas violas showed lower values in the AP and EP impact categories. The most impactful phase was the propagation, accounting on average for 42% of the total emissions. Overall, the findings highlighted a higher environmental load for the production of both begonias and violas packaged flowers, especially if in small containers, rather than as potted plants, with an emission percentage increase from 8% to 17% among the impact categories.

Potatoes (Solanum tuberosum L.) are an essential food for the human diet and thus represent an important source of biologically active substances. This study aimed at investigating the content of bioactive substances (total anthocyanin and polyphenol contents and chlorogenic acid) in seven potato varieties (Belana, Cecile, Magenta Love, Mozart, Talentine, Toscana, and Violet Queen) with various flesh and skin colors. To evaluate the impact of potato maturity on the analyzed parameters, potato samples were harvested in two different periods (1st harvest—July and 2nd harvest—September). Total anthocyanin and polyphenol contents were determined spectrophotometrically, and chlorogenic acid by the HPLC-DAD method. Varieties with a colored flesh (Magenta Love and Violet Queen) showed the highest content of bioactive substances. The maturity level significantly (p < 0.05) affected the total content of anthocyanins and polyphenols in potatoes. Early to medium early varieties (Belana and Magenta Love) showed an increase in chlorogenic acid content during maturation, while in other varieties, chlorogenic acid decreased due to higher maturity. In terms of the content of bioactive substances with a possible positive effect on human health, the consumption of potatoes with colored flesh could be recommended. [ABSTRACT FROM AUTHOR]
