Volunteered Geographic Information (VGI) represents a growing source of potentially valuable data for many applications, including land cover map validation. It is still an emerging field and different approaches can be used to take value from VGI, but also pros cons are related its use. Therefore, since it timely get overview the subject, aim this article review use VGI as reference The main platforms types that useful analysed. Since quality fundamental issue in validation, procedures by...

The cultivation of marginal lands for bioenergy production has recently become a topic research interest the agronomic and agricultural economy scientific communities. growing availability arable land in Mediterranean regions, as consequence decline cereal cropping systems grain legume, provides ample opportunities performing successful feedstock on unmanaged areas. This paper seeks to capture analyze ongoing emerging questions concerning area framework sustainability indicators. A...

Geo-tagged photographs are used increasingly as a source of Volunteered Geographic Information (VGI), which could potentially be for land use and cover applications. The purpose this paper is to analyze the feasibility using spatial information three cases related cover: Calibration, validation verification. We first provide an inventory metadata that collected with geo-tagged then consider what elements would essential, desirable, or unnecessary aforementioned cases. were extracted from...

The consequences of climate change on food security in arid and semi-arid regions can be serious. Understanding impacts water balance is critical to assess future crop performance develop sustainable adaptation strategies. This paper presents a impact study the components an agricultural watershed Mediterranean region. restructured version Soil Water Assessment Tool (SWAT+) model was used simulate hydrological Sulcis (Sardinia, Italy) for baseline period compared projections at end 21st...

Invasive species pose a growing threat to global biodiversity, agricultural productivity, and ecosystem health, as climate change worsens their spread. This study focused on modelling the current projected distribution of Japanese beetle (Popillia japonica Newman), an invasive pest with potentially devastating impacts crops natural vegetation across Europe. Using MaxEnt model, we integrated occurrence data bioclimatic variables, analyzing future scenarios based Shared Socio-economic Pathways...

Homegrown fruits and vegetables are gaining popularity in many metropolitan areas with several facets connected to the wider urban agriculture phenomenon. At same time, relationship between food production irrigation water is pivotal terms of resource management. In this paper, we investigated savings through collection use harvestable rainwater from buildings’ rooftops irrigate 2631 gardens area Rome (Italy). The methodology makes existing geospatial data derived satellite image...

Assessing crop yield trends over years is a key step in site specific management, view of improving the economic and environmental profile agriculture. This study was conducted 11.07 ha area under Mediterranean climate Northern Italy to evaluate spatial variability relationships between six remotely sensed vegetation indices (VIs) grain (GY) five consecutive years. A total 25 satellite (Landsat 5, 7, 8) images were downloaded during growth obtain following VIs: Normalized Difference...

Predicting the availability and quality of freshwater resources is a pressing concern in Mediterranean area, where number agricultural systems depend solely on precipitation. This study aims at predicting streamflow nonpoint pollutant loads temporary river system basin (Sulcis Sardinia, Italy). Monthly discharge, suspended sediment, nitrate nitrogen, total mineral phosphorus, dissolved oxygen in-stream monitoring data from gauge stations were used to calibrate validate Soil Water Assessment...

Availability of georeferenced yield data involving different crops over years, and their use in future crop management, are a subject growing debate. In 9 hectare field Northern Italy, seven years data, including wheat (3 years), maize for biomass (2 sunflower, sorghum, comprising remote (Landsat) normalized difference vegetation index (NDVI) during central stages, soil analysis (grid sampling), were subjected to geostatistical (semi-variogram fitting), spatial mapping (simple kriging),...

During the last years, in city of Rome (Italy) due to social and economical trends urban agriculture is a growing phenomenon. Residential kitchen gardens are custom started past, but recently they experienced strong increase with concentration fringe. The amount extension these cultivated parcels has been inventoried by Italian Institute Agricultural Economics (INEA) 2014 methodology based on photointerpretation very high resolution imagery provided Google Earth. spatial dataset, after field...

In the context of environmental sustainability there has been an increasing interest in bioenergy production from renewable resources, and is expected that European biofuel energy crops will increase as a consequence achievement policy targets. The aim this paper to assess agronomic feasibility biomass crop cultivation provide profitable feedstocks marginal heavy-metal polluted area located Sulcis district, Sardinia (Italy). Results literature review unpublished data field trials carried out...

A dimensionless methodology to evaluate the water saving obtainable from large-scale implementation of domestic rain harvesting (RWH) systems in urban areas is presented. The combines use regressive relationships for evaluation based on results rainwater tank balance and catchment-wide information obtained geospatial databases. adopted RWH scheme included internal toilet flushing external garden irrigation. An application a portion city Rome, Italy showed allow systematic accurate system...

Urban agriculture in Global North cities is strongly promoted as a sustainable solution to achieve different goals, such food production, quality of life, and well-being. Although several attempts have been made evaluate urban few studies investigated production multitemporal geospatial way considered per capita population needs, gender, age strata consumption. This study presents spatiotemporal quantification the city Milan (Italy) for assessing self-provisioning potential. We utilized...

The paper proposes a methodology to assess water consumption in urban agriculture. Green and blue footprints were calculated for five selected community gardens (CGs) Rome (Italy) based on weather, crops, yields. Then, the requirement all CGs of city, identified by means geodatabase, was estimated. For cultivated area 4.06 ha, an overall 22,036 m3 (13,596 green 8,440 blue) resulted from assessment. Considering also efficiency irrigation system, would reach 20,000 worst scenario (furrow irrigation).

ABTRACTSoil and weather data were used to analyse spatio-temporal yield patterns of winter cereals (wheat) spring dicots (sunflower coriander) in an 11-ha field Northern Italy (44.5° N, 12.2° E), during 2010–2014. Three stability classes (YSCs) established over multiple years, based on characteristics across the field: high yielding stable (HYS), low (LYS), unstable. The HYS class (46% area) staged a 122% relative with temporal variability. unstable (24% was slightly more productive (83%...
