“…The areas considered as marginal to cultivation (15%) were concentrated in the transition region, while unsuitable areas (48%) prevailed particularly in the North and West of Minas Gerais. Considering the projections of changes in air temperature and rainfall (Figures 1 and 2), there was a reduction in the suitable area and a displacement of the marginal and unsuitable areas towards the South of the state at the end of the XXI century ( Figure 5 and Table 1), agreeing with some results for the Mediterranean, which indicates displacement of suitable areas towards the opposite direction in relation to the Equator line (Tanasijevic et al, 2014).…”

“…Additionally, high temperatures, above 35 ºC (Wrege et al, 2015), in the flowering period, more precisely in the beginning of the flowering, from early August to late September (Oliveira et al, 2012), are harmful to the olive crop, because they cause flower abortion (García-Mozo et al, 2010). García-Mozo et al (2010) evaluated phenological tendencies in Southern Spain in response to climate changes and observed that the increase in mean annual temperature also damages pollination, shortens the duration of the flowering and fruiting stages (Tanasijevic et al, 2014) and increases the respiration of the cell tissue (Taiz & Zeiger, 2009), particularly in plants with C 3 metabolism like olive, leading to lower yield. High air temperatures (above the optimal temperature, e.g.…”

“…Unfavorable climatic conditions can cause physiological disorders in the plants and thus affect their development, growth and yield (Tanasijevic et al, 2014), and water stress and irregular temperature are the main limiting factors to olive cultivation (Moriondo et al, 2015).…”

Minas Gerais is vulnerable to climate change, with negative impacts on water balance and changes in the cultivation of several crops. Currently, the olive crop has been an alternative source for farmers, especially those in the South of the state. However, there is no information on areas with climatic conditions suitable for olive cultivation, as well as the possible impacts of climate change. The aim of this study was to verify the impact of climate projections on water balance and agroclimatic zoning for olive cultivation in the Minas Gerais, based on current climate conditions (1980-2011), and different climate change projections for three future periods (2011-2040, 2041-2070 and 2071-2100). For the current climate, Minas Gerais showed 37% of suitable area, 15% of marginal area and 48% of unsuitable area for olive cultivation. For the period 2071-2100, only 4% was classified as suitable area, 6% as marginal area and 90% as unsuitable. Projections of climate change, of both temperature and rainfall, will affect the olive cultivation, substantially reducing the suitable area in the entire state.

“…Various aspects of olive tree response to global warming have been modelled for the Mediterranean Basin including flowering and other phenological stages (e.g., Osborne et al, 2000;De Melo-Abreu et al, 2004;García-Mozo et al, 2010), insect damage and olive yields (Ponti et al, 2014), and crop evapotranspiration (Tanasijevic et al, 2014). It has been estimated that only fairly large changes in temperature (i.e., an increase of 3°C) would lead to a significant increase in abnormal flowering events for Spanish and Portuguese sites (De Melo-Abreu et al, 2004).…”

Olive production has expanded significantly from the Mediterranean Basin into the New World over the last two decades. In some cases, cultivars of European origin have been introduced at a large commercial scale with little previous evaluation of potential productivity. The objective of this study was to evaluate whether a temperature-driven simulation model developed in the Mediterranean Basin to predict normal flowering occurrence and flowering date using cultivar-specific thermal requirements was suitable for the low latitude areas of Northwest Argentina. The model was validated at eight sites over several years and a wide elevation range (350–1200 m above mean sea level) for three cultivars (‘Arbequina’, ‘Frantoio’, ‘Leccino’) with potentially different chilling requirements. In ‘Arbequina’, normal flowering was observed at almost all sites and in all years, while normal flowering events in ‘Frantoio’ and ‘Leccino’ were uncommon. The model successfully predicted if flowering would be normal in 92% and 83% of the cases in ‘Arbequina’ and ‘Frantoio’, respectively, but was somewhat less successful in ‘Leccino’ (61%). When flowering occurred, the predicted flowering date was within ± 7 days of the observed date in 71% of the cases. Overall, the model results indicate that cultivar-specific simulation models may be used as an approximate tool to predict whether individual cultivars will be successful in new growing areas. In Northwest Argentina, the model could be used to identify cultivars to replace ‘Frantoio’ and ‘Leccino’ and to simulate global warming scenarios.

“…Considering the foreseen future climate conditions, some studies have evaluated the impact of climate change on olive yield, projecting a yield decrease at the end of 21st century due to the combined effect of increased mean and extreme temperatures, reduced precipitation Viola et al, 2013), and increased net irrigation requirements (Rodríguez Díaz et al, 2007;Tanasijevic et al, 2014). However, to understand the impacts of climate change on crop yield is essential the analysis of the effects of such change, especially the temperature and daylength changes, on its phenology Schwartz, 1999;.…”
