According to the Guardian on Aug 27, 2022, pistachios are replacing crops such as olives and grapes to become the "Green gold" of Spanish farmers. It is reported that the income of local farmers for each kilogram of olives produced is 0.65 euros 0.85 euros, and that of grapes is about 0.65 euros. However, pistachios can be sold for 6 to 8 euros.
According to the report, the government of Castilla-La Mancha region has been studying drought-resistant crops since 1986. The researcher said, "Pistachios are suitable for the local climate. They can resist high temperatures and cold, and can grow in barren shallow soil. Although it takes at least 7 years to harvest the first batch of pistachios, many farmers believe it is worth it." Last year, Spain harvested 2800 tons of pistachios on 70000 hectares of land, almost all from the region.
