“…All the weather stations satisfied synoptic criteria of station location and instrument quality and all data were quality‐checked by the native networks. Grids with 0.0166° of resolution were obtained by means of squared inverse distance weighting, homogenised for elevation by means of monthly altitudinal gradients (Mariani et al , ). Hourly time‐series of temperature were obtained from the gridded dataset by means of the Parton and Logan () hourly generator.…”

Background and Aims The growth and development of grapevine is constrained by temperature, affecting the bulk of physiological processes of the plant. The aim of this study was to evaluate the effects of climate change on thermal resources and limitations in the context of Georgia, one of the oldest viticultural areas in the world. Methods and Results The analysis on daily series of temperature for the time period 1974–2013 for the main viticultural areas of Georgia shows that an abrupt change to warmer temperature occurred in 1994, leading to a decline in low temperature stress and an increase in high temperature stress, associated with more frequent heat waves. The availability of thermal resources for grapevine growth remained unchanged. Conclusions In Georgia, the shift to warmer temperature did not affect the availability of thermal resources for grapegrowing. Although some attention should be paid to possible damage due to an earlier budburst and increased frost risk. Furthermore, it is important to highlight the strong increase of summer heatwaves with potential negative impacts on grape composition and phenolic maturity, when combined with severe water stress. Significance of the Study Quantitative studies of the effects of climate change on Georgian viticulture are essential to develop adaptation strategies based on either germplasm (e.g. rootstocks and cultivars) and agronomical practices (e.g. pruning, trellis systems, soil and water management).

“…Missing data were reconstructed with the geostatistical approach described in Mariani et al [14]. For each unknown missing point, neighbor points temperatures were homogenized to the same altitude of the unknown point (−0.5 • C for 100 m increase in altitude) and then the missing temperature was obtained with a weighted average of the values available at the known points using an inverse squared-distance weight.…”

The ornamental plant production in greenhouses is widespread. A quantitative assessment of greenhouse energy consumption and its variability in space and time is strategic to improve the sustainability of the cultivation. The specific environmental features of the cultivation areas can strongly affect the sustainability of the production. A dynamic simulation model of greenhouse energy balance with an hourly time step was developed and parameterized for a state-of-the-art greenhouse to evaluate the heating requirements for cut-flower roses. This ornamental crop has been used as model species for its high energy requirement for flower production. The energy demand for rose production has been analyzed with an energy balance model with an hourly time step. After a preliminary analysis on the period 1973–2019, the final analysis was carried out on the 30-year period (1990–2019), representative of the current climate. Results show a gradient southwest–northeast of energy needs with relevant effects on economic and environmental sustainability. More specifically, four large sub-areas are identified, namely the central-southern Mediterranean (yearly requirements below 600 MJ m−2 year), the northern Mediterranean, and the area influenced by the mitigating effect of the Atlantic Ocean (600–1200), the central-European area (requirements of 1200–1800), and the Northern European area (above 1800).

“…The quantification of the energy requirements of glasshouse food production has been investigated previously in the literature, for example in studies such as those in ASABE (2008), Chalabi et al (2002), Gupta and Chandra (2002), Moreton and Rowley (2012), Ozkan et al (2011aOzkan et al ( , 2011b, Papadopoulos and Hao (1997), Subi c et al (2015), Mariani et al (2016), Luo et al (2005) and Wass and Barrie (1984). In Papadopoulos and Hao (1997), the authors investigated the effect of the glasshouse cover material in three tomato glasshouses focusing on yields, energy requirements and productivity, whereas Gupta and Chandra (2002) focused on the effects of a glasshouse's design on its energy requirements, with a particular interest in the shape and orientation of a glasshouse in India.…”

“…Interestingly these studies observed the direct energy use in terms of fuel and electricity as well as indirect energy use due to manure and chemical fertiliser. Mariani et al (2016) investigated the heating requirements of glasshouse tomato production in 56 sites located in Europe and the Mediterranean, while focusing on space and time variability. This paper considered the heating requirements of glasshouses over very wide territories and long times with particular emphasis on the impact of climate change.…”

“…This paper considered the heating requirements of glasshouses over very wide territories and long times with particular emphasis on the impact of climate change. Interestingly, the study of Mariani et al (2016) generated hourly temperature and radiation data by using only maximum and minimum daily temperatures in terms of external weather input data. This approach has the advantage of not relying on detailed weather databases and can be advantageous in performing macroscale analyses which include areas with very limited weather data.…”

a b s t r a c tQuantifying the use of resources in food production and its environmental impact is key to identifying distinctive measures which can be used to develop pathways towards low-carbon food systems. In this paper, a first-principle modelling approach is developed, referred to as gThermaR (Glasshouse-Thermal Requirements). gThermaR is a generic tool that focuses on the energy requirements of protected heated production, by integrating holistic energy, carbon, and cost modelling, food production, data analytics and visualization. The gThermaR tool employs historic data from weather stations, growing schedules and requirements specific to grower and product needs (e.g. set-point temperatures, heating periods, etc.) in order to quantify the heating and cooling requirements of glasshouse food production. In the present paper, a case study is reported that employs a database compiled for the UK. Another relevant feature of the tool is that it can quantify the effects that spatial and annual weather trends can have on these heating and cooling requirements. The main contribution of this work, therefore, concerns the development a tool that can provide a simple integrated approach for performing a wide range of analyses relevant to the thermal requirements of heated glasshouses. The tool is validated through collaborations with industrial partners and showcased in a case study of a heated glasshouse in the UK, offering the capacity to benchmark and compare different glasshouse types and food growth processes. Results from the case study indicate that a significant reduction in the heating requirement and, therefore, carbon footprint, of the facility can be achieved by improving key design and operational parameters. Results indicate savings in the peak daily and annual heating requirements of 44e50% and 51e57% respectively, depending on the region where the glasshouse is located. This improvement is also reflected in the carbon emissions and operating costs for the different energy sources considered. Furthermore, the temporal variability/uncertainty of the annual energy requirements and of the peak daily energy requirements are found to be considerably lowered through improvements to the glasshouse attributes. Overall, gThermaR proves its value in quantifying and identifying key factors that have a significant impact on energy requirements of heated glasshouses. Such valuable outputs are invaluable for stakeholders in the food industry that have an interest in mapping the sustainability and mitigating the carbon footprint of their supply chain processes.
