This is significant because agriculture playsĪ key role in food supply in 2017 it accounted for 2.59 % of GDP in Longer drought events in coming decades (Alcamo et al., 2007 Dai, 2011 įorzieri et al., 2016 Giorgi and Lionello, 2008 Spinoni et al., 2018 It has been suggested that precipitation and temperatureĬhanges in the western Mediterranean region will lead to more severe and Weather events (Giorgi and Lionello, 2008 Webber et al., 2018 Wigley,Ģ009) that will impact ecosystems and economic sectors (Asseng et al., 2014 With a rise in temperature, will inevitably bring more extreme and severe
It is also expected that future changes in the precipitation regime, along
Interannual and intra-annual rainfall variability (IPCC, 2014, EEA, 2017). Southwestern Europe are expected to undergo a critical decline in waterĪvailability as a consequence of reduced precipitation and an increase in Subject to the potential impacts of climate change. The Mediterranean region is one of the major areas in Europe likely to be Responses across the country were related to season and the magnitude of Region, period of the year, and the drought timescale. The results also suggested thatĭifferent patterns of yield response to drought occurred depending on the Showed that drought indices calculated at different timescales (SPI, SPEI) Spatial scales and temporal periods were used in the analysis. Yields in Spain, including the Standardized Precipitation Evapotranspiration Index (SPEI), the Standardized Precipitation Index (SPI),ĭrought Severity Index, PDSI Palmer Z Index, Z Index Palmer Hydrological Drought Index, PHDI Palmer Modified Drought Index, PMDI), and the Standardized Variousĭrought indices have been used to assess the influence of drought on crop The impact of the weather on crops, and particularly the impact of drought.ĭrought indices are the most effective tool for that purpose. As the agriculture sector is vulnerable to climate, it isĮspecially important to identify the most appropriate tools for monitoring On two representative rainfed crops in Spain (wheat and barley) wereĪssessed. Drought events are of great importance in most Mediterranean climate regionsīecause of the diverse and costly impacts they have in various economic
