Were I am, in Castelo Branco, Portugal, the prices are very cheap (that's why I bought here), but it all depends, it's just a matter of searching.
Regarding your question, it has more to do with what you do with the land. Iberia is not comparable to Jordan because Jordan get's very little rainfall, we don't. It's very hot and dry here in the Summer that is true, but it also rains a lot every Winter and Spring (it's June and it's been raining almost every day since February) so it's more about water management and storage than water scarcity.
Most pieces of land here will have a well or a spring or both. I only have a well and it has water all year round. Right now I'm building a water tank and a pond to store more water and I've also done swales. I'm trying to create a forest garden and, as trees get bigger my land will have more shade and more mulch making it a lot cooler and more moist.
There are a lot abandoned and neglected farms around here with lots of fruit trees and plants heavy with fruit and nobody waters them for years and they still thrive, and I'm not talking about cactus
but apples, citrus, figs, pears, cherries, grapes, etc.
