“…The analysis of the multiple linear regression models and the spatiotemporal distribution of the GDD for both cultivations closely corroborate published research which estimated the GDD using the same or a similar dataset [5,78,79], but in different timescale [5,70], by climatic models such as CMIP5 and REGCM3 [80,81] for representative concentration pathways, e.g., RegCM4, RCP4.5, RCP8.5, A1B, A2, and B2 [5,35,81,82]. Generally, the results are in clear agreement (quantitatively and qualitatively) with publications focused on the current and future agroclimatic conditions in Europe and, especially, in the studied area [74,79,81,[83][84][85][86].…”

Spatiotemporal Estimation of the Olive and Vine Cultivations’ Growing Degree Days in the Balkans Region

Olive and vine cultivations are two of the most important crops in Europe, yielding high quality and value food products. The climate change over the Balkans may elevate the agroecological pressure for the established crops and shift their cultivations areas. One of the widely-used agroclimatic indices is the growing degree days (GDD) which accumulates the necessary thermal units for the selected crops. Despite the advances on the agroclimatic research, there are few available methods for spatiotemporal estimation of this useful index. So, this research is focused on the construction of simple and reliable equations for the calculation and projection of olive and vine cultivations’ GDD over the Balkans. The models’ input parameters are the time, the altitude, the distance from the seashore, and the latitude. Its assembly is made by the extracted spatial data, combined with the Agri4Cast dataset for the period of 1980 to 2018 incorporating the regional climate change trend. The results indicate that the most influential parameter is the time, followed by the latitude, for both cultivations. According to the projections, as quantified by GDD, a vast sprawl of olive and vine cultivation areas will have been formed to the northern parts of the studied area. To be more precise, the viticulture could expand spatially by 28.8% (of the Balkans area) by 2040, and by 15.1% to 2060, when the olive cultivations’ area could sprawl 23.9% by 2040 and 20.3% by 2060.

“…The results confirm that GDD is a robust agro-climatic indictor of the impact temperature change at the regional scale on crop growth in a thermally extreme mid-latitude climate. This coincides with the findings [39,43,45,61,63,64] in different climates regimes. Clearly, a full impact assessment should include the role of other climate variables such as precipitation and soil moisture deficit, evapotranspiration, solar radiation [39,45,64].…”

“…Most analyses of regional temperature datasets in GDD research projects have used growing season averages or time series of monthly mean temperatures; only fewer studies have been done using daily time series, which may give results that are not the same as those using monthly mean statistics [59,60]. More recently, several studies have focused on agroclimatic indices per se rather than on sensitivity evaluations [37,44,[61][62][63][64][65].…”

Climate is a key factor in agriculture, but we are unable to adequately predict future climates. Although some studies have addressed the short and long-run impacts of climate change on agriculture, few of them specifically focused on the analysis of its thermal component. Climatic regions with an extreme thermal range are a special case, as seasonal contrasts complicate the picture. Based on the above, the purpose of the paper is twofold. First, we review methods and indices used for the estimation of changes in the thermal component of the climate and demonstrate the usefulness of a sensitivity assessment methodology that gives some indication of the likely spatial extent of areas of high or low sensitivity to climate change and the size of the potential impact of that change, which is specifically beneficial in regions with high temperature extremes. Secondly, we constructed a composite indicator, called the Growing Degree Day Sensitivity Index (GDDSI) and defined as the percentage change in Growing Degree Day (GDD) for warming scenarios +1, +2 and +3 °C. GDDs were calculated for threshold base air temperatures of 0, 5, 10 and 15 °C, and a high-temperature limit of 30 °C. A GDD sensitivity analysis was applied to the thermally extreme climate of the Russian Far East. We analyzed the data of 50 weather stations across the study region over the period 1966–2017. The results show a strong GDDSI north-to-south gradient. In most cases, the sensitivity does not increase significantly as the warming rate increases. The higher the base threshold, the higher the sensitivity: GDDs with a threshold at 15 °C had the highest sensitivity in the far north of the study area where conditions are currently marginal for crop growth. The sensitivity analysis circumnavigates the difficulty of uncertainty in knowing what future climate to expect and informs planning decisions. The mapped results are useful for identifying areas of high sensitivity to climate change as well as the magnitude of the potential impact of that change.

“…Occurrence of cold-stress events during the early growth stages of the crop might be significantly reduced (Giannakopoulos et al, 2011). By 2050, the growing degree days per cultivation season in Greece are expected to increase at least by 150, depending on the 6 area (Paparrizos and Matzarakis, 2016;Paparrizos and Matzarakis, 2017). According to Kukal and Irmak (2018), GDDs and yields are positively correlated, thus cotton yields might increase.…”

Through the last century, the increased greenhouse gases emissions altered the atmosphere’s composition and resulted to the phenomenon known as climate change. Climate change threatens the sustainability of the agricultural sector in the Mediterranean region. Droughts and extreme heat waves will probably become more frequent in the next few decades, thus maintaining sufficient yields in heat and drought susceptible major crops will be challenging. In Greece, cotton is of paramount economic importance. Besides the fact that it is regarded as the most significant fiber crop, Greece is the main cotton producer of the European Union. The aim of the present review was to examine the environmental factors that might affect cotton production in Greece and assess whether (or not) climate change has the potential to limit the productivity of this crop in the near future. According to the existing literature, cotton can adapt to the changing climate. Climate change-induced elevated CO2 levels and temperatures might even benefit cotton. The mitigation of the adverse effects of climate change is possible via the adaptation of site-specific agronomic practices. A simplistic framework, based on the literature and the goals of the European Union, that aims to the preservation of sufficient cotton yields in Greece is proposed in the present study.
