of ecosystems. It can be found from fauna and flora with typical characteristics of the steppes and deserts to the enormous ornithological richness that abounds on the banks of the rivers. Of special natural importance is the one known as Aiguabarreig ("water mixture" in Catalan) that is formed in the final stretch of the confluence of the Cinca, Segre and Ebro rivers in Mequinenza. Climatography The weather is characterized by being continental and with a lack of rain, a fact that determines the vegetation of the Bajo / Baix Cinca. The warmest months are July and August, where the temperature can reach 35 °C or sometimes up to 40 °C. On the other hand, in the cold months of December and January the temperatures range between 0 °C and -5 °C. The region receives the cold and dry wind of the deer that descends along the Ebro valley. The average rainfall level ranges between 300 and 400 mm distributed very irregularly throughout the annual period. Prolonged periods of drought are common during the year. Population The socio-economic transformation experienced in Spain in the 1960s caused territorially a double current of emigration: from the interior areas to the periphery and from the rural to the urban centers. For the Bajo / Baix Cinca region, as for other areas of Aragon, it meant a strong depopulation of its rural nuclei and the concentration of a part of the population in the capital of the region. The population of the region represents 11.03% of the total of the province of Huesca. The proportion between men and women is quite homogeneous. Fraga is where most of the population is concentrated, followed by Mequinenza with almost 9.64% of the county's total. All municipalities have a historical decrease with the exception of Fraga. Economy The Bajo / Baix Cinca region is one of the most dynamic regions in Aragon, mainly promoted by the agricultural sector. The percentage of the population employed in agriculture with respect to the total is 25.5%, creating an important added value in the sweet fruit sector. The Bajo / Baix Cinca is the Aragonese region with the most cultivated hectares in this sector. The Bajo / Baix Cinca has always been an agricultural area for two fundamental reasons: the first one because traditionally and culturally it has been associated to the countryside and the second one due to the weather factor and
