There are 4 main water reliant parts of an economy, agriculture, fishing, manufacturing and energy production. Agriculture isn't a very important part of Spain's economy because of the soil being a bad quality.
Economy and How it gets impacted by water
In my opinion fishing will be the part of the economy that gets the most impacted if there is a water shortage.Rivers would be drier, causing fish to leave. Agriculture isn't very big.Hydroelectricity isn't used much anymore and manufacturing doesn't consume too much water.
Poverty and Access to Freshwater
Women and girls spend a lot of their time walking to and back from rivers. Because of this many young girls are not educated. Also they don't even have a lot of relaxing time. This doesn't allow their minds to grow and learn. These women are also exhausted by this routine.
