“…Soils also play an important role in global food security, water security, biofuel security and human health Keesstra et al, 2016). However, many soils are under threat and unable to fulfil the food demand due to loss of soil fertility, erosion, drought and climate change (Muluneh et al, 2015;Tsozué et al, 2015;Mwango et al, 2016;Potopová et al, 2016;Singh et al, 2016). This situation might worsen due to increased population pressure on soil worldwide and thus enhance the degradation of soil.…”

“…Following the concept of the SPI, the SPEI enables comparison of drought characteristics at various timescales among regions, independently of their climatic conditions. The SPEI has been widely used in drought-related studies, including to investigate the impacts of drought on various crops worldwide Kuhnert et al, 2016;Peña-Gallardo et al, 2018b;Potopová et al, 2016b;Vicente-Serrano et al, 2012).…”

“…Droughts are difficult to measure and quantify , and consequently a wide range of drought indices have been developed to provide tools for quantifying the effects of drought across different sectors (Zargar et al, 2011). In this respect, drought indices are the most widely used method for monitoring drought impacts on agriculture; examples of their use available in the scientific literature include that in Europe (Hernandez-Barrera et al, 2016;Potopová et al, 2016a;Sepulcre-Canto et al, 2012;Vergni andTodisco, 2011), America (McEvoy et al, 2012;Quiring and Papakryiakou, 2003), and Asia (Ebrahimpour et al, 2015;Wang et al, 2016a). However, there is no general consensus on the most suitable indices for this purpose (Esfahanian et al, 2017).…”

Drought events are of great importance in most Mediterranean climate regions because of the diverse and costly impacts they have in various economic sectors and on the environment. The effects of this natural hazard on rainfed crops are particularly evident. In this study the impacts of drought on two representative rainfed crops in Spain (wheat and barley) were assessed. As the agriculture sector is vulnerable to climate, it is especially important to identify the most appropriate tools for monitoring the impact of the weather on crops, and particularly the impact of drought. Drought indices are the most effective tool for that purpose. Various drought indices have been used to assess the influence of drought on crop yields in Spain, including the Standardized Precipitation Evapotranspiration Index (SPEI), the Standardized Precipitation Index (SPI), the Palmer drought indices (Palmer Drought Severity Index, PDSI; Palmer Z Index, Z Index; Palmer Hydrological Drought Index, PHDI; Palmer Modified Drought Index, PMDI), and the Standardized Palmer Drought Index (SPDI). Two sets of crop yield data at different spatial scales and temporal periods were used in the analysis. The results showed that drought indices calculated at different timescales (SPI, SPEI) most closely correlated with crop yield. The results also suggested that different patterns of yield response to drought occurred depending on the region, period of the year, and the drought timescale. The differing responses across the country were related to season and the magnitude of various climate variables.

Abstract. Drought events are of great importance in most Mediterranean climate regions because of the diverse and costly impacts they have in various economic sectors and on the environment. The effects of this natural hazard on rainfed crops are particularly evident. In this study the impacts of drought on two representative rainfed crops in Spain (wheat and barley) were assessed. As the agriculture sector is vulnerable to climate, it is especially important to identify the most appropriate tools for monitoring the impact of the weather on crops, and particularly the impact of drought. Drought indices are the most effective tool for that purpose. Various drought indices have been used to assess the influence of drought on crop yields in Spain, including the standardized precipitation and evapotranspiration index (SPEI), the standardized precipitation index (SPI), the Palmer drought indices (PDSI, Z-Index, PHDI, PMDI), and the standardized Palmer drought index (SPDI). Two sets of crop yield data at different spatial scales and temporal periods were used in the analysis. The results showed that drought indices calculated at different time scales (SPI, SPEI) most closely correlated with crop yield. The results also suggested that different patterns of yield response to drought occurred depending on the region, period of the year, and the drought time scale. The differing responses across the country were related to season and the magnitude of various climate variables.
