“…Many semiarid regions of southwestern Europe are expected to undergo a critical decline in water availability as a consequence of reduced precipitation and an increase in interannual and intra-annual rainfall variability (IPCC, 2014, EEA, 2017. It is also expected that future changes in the precipitation regime, along with a rise in temperature, will inevitably bring more extreme and severe weather events (Giorgi and Lionello, 2008;Webber et al, 2018;Wigley, 2009) that will impact ecosystems and economic sectors (Asseng et al, 2014;Tack et al, 2015). It has been suggested that precipitation and temperature changes in the western Mediterranean region will lead to more severe and longer drought events in coming decades (Alcamo et al, 2007;Dai, 2011;Forzieri et al, 2016;Giorgi and Lionello, 2008;Spinoni et al, 2018;Vicente-Serrano et al, 2014).…”

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 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.

“…Although previous studies reported differences among some of the above three indices (e.g., the SPDI and the SPEI; Ghabaei Sough et al, 2018), others have reported similarities in their performance in assessing agricultural drought impacts (Labudová et al, 2016;Peña-Gallardo et al, 2018a). The similar magnitudes of their correlations suggest a similar ability to characterize the impact of drought on crop yields.…”

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.

“…Scalogram analysis is used to determine the hierarchy of service centers which will later be used as guidelines for establishing the processing industry (Sough, 2018). In comparison, the Geographic Information System (GIS) is used to map the sub-district in the Demak Regency, which has the advantage of food plant commodities and a map of the processing sub-industry.…”

The agricultural sector has an essential role in the regional economy of the Demak Regency because the agricultural sector is the leading sector. The area of agricultural land in the Demak Regency that continues to decrease requires detailed mapping portraits of each food crop commodity per sub-district. This study aims to analyze the leading food crop commodities in each sub-district, analyze the regional growth rate of food crop commodities, and map the food crop commodities developed in Demak Regency. This research is a quantitative study using secondary data. Data analysis method using Location Quotient, Shift Share, Scalogram, and Geographic Information System. Analysis tools to identify potential, competitive conditions between commodities and sectors, regional hierarchy by type, availability of the number of infrastructure facilities, and graphical mapping. The results showed that rice and soybeans were the leading commodities with advanced and competitive growth rates in Demak Regency. The superior rice commodities in the districts
