Xerophilous

Relating to plants or plant formations adapted to the lack of moisture in arid environments, such as those with widespread or deep roots, reduced leaves, or leaves transformed into thorns, among other mechanisms. Examples include the palmetto and esparto grass, or, in the Canary Islands, the cardón.

SAU (Utilized Agricultural Area)

The total area of cultivated land and permanent pastureland. In Spain, this represents 23.2 million hectares (2016).

Dry land

Extensive farming system, in which there is no water input other than that provided by nature through rainfall, resulting in lower yields.

Floor

The surface of the Earth's crust where the lithosphere, biosphere, and atmosphere come into contact. It results from the alteration of the parent rock by climate and the action of living beings. In its various types, it is made up of layers or horizons. It is a finite and nonrenewable resource.

Irrigable surface

This is the surface area that can be irrigated with the existing irrigation infrastructure and that has actually been irrigated at some point.

Irrigated surface

It is the area that has actually been irrigated in a specific year.

Crop rotation

Succession of crops on the same plot, for which the cultivated land is divided into several parts called leaves.

Irrigation

An intensive farming system based on the extraordinary contribution of water, using techniques that provide the necessary amount of water to improve farm production, compensating for the absence or insufficiency of atmospheric precipitation. The main irrigation techniques are drip irrigation, sprinkler irrigation, and gravity irrigation.

Irrigation consolidation program

The irrigation consolidation program outlined in the National Irrigation Plan H-2008 of May 2001 (MAPA) is associated with actions on irrigable land where the allocation index is less than 25%. The allocation index is the ratio between the difference between the water supply and the theoretical demand […]

Irrigation improvement program

The irrigation improvement program included in the National Irrigation Plan H-2008 of May 2001 (MAPA) is associated with actions on irrigated land where the allocation index is greater than one. The allocation index is the ratio between the difference between water supply and demand […]
