Geography of Andalusia Andalusia occupies the southernmost part of the Iberian Peninsula, spanning from the Atlantic coastline near Cádiz and Huelva to the Mediterranean shores by Almería and Málaga, and inland toward Jaén and Córdoba. The region encompasses major mountain systems including the Baetic Cordillera and the Sierra Nevada, extensive river basins such as the Guadalquivir, and coastal plains like the Costa del Sol, producing a mosaic of landscapes shaped by tectonics, climate and long histories of human land use linked to cities like Seville, Granada and Córdoba.

Physical geography

Andalusia's physical geography is dominated by the Baetic System with subranges including the Sierra Nevada, Sierra Morena and Subbaetic Range, framing the Guadalquivir Basin and the Betic Corridor that connects to the Rif in Morocco and the Strait of Gibraltar near Algeciras and Tarifa. Coastal geomorphology features Atlantic littoral zones by Cádiz and Huelva, Mediterranean headlands around Málaga and Almería, and barrier systems such as the Doñana marshes and the Marismas del Odiel. Prominent physiographic features include the Genil valley, the Guadalhorce gorge, the Despeñaperros pass linking Andalusia to Castilla–La Mancha, and geomorphological units like the Prebetic, Penibaetic and Subbetic sectors influencing local relief around Ronda, Úbeda and Antequera.

Climate

Andalusian climate ranges from oceanic-influenced Mediterranean on the Costa de la Luz and parts of Cádiz and Huelva to semi-arid (steppe and desert) conditions near Almería and the Cabo de Gata, while interior basins and highland areas experience continental Mediterranean climates with cold winters in the Sierra Nevada and warm summers in the Guadalquivir valley. Coastal cities such as Málaga, Almería, Cádiz, Huelva and Motril show moderated temperatures due to Atlantic and Alboran Sea influences, whereas inland locales like Jaén, Córdoba and Granada display extreme summer heat episodes and occasional snow at high elevations on Mulhacén and Veleta. Climatic variability is modulated by phenomena including the Azores High, African anticyclones, the Iberian thermal low, and occasional impacts from the North Atlantic Oscillation and Mediterranean cyclogenesis that affect precipitation patterns across provinces like Sevilla, Córdoba and Cádiz.

Geology and soils

Andalusia's geology reflects the convergence of the Eurasian and African plates with major tectonic structures in the Betic Cordillera, Variscan basement outcrops in the Sierra Morena, and Neogene basins such as the Guadalquivir depression filled by Quaternary alluvium. Rock assemblages include metamorphic complexes near the Alpujarras, Mesozoic carbonates in the Subbetic and limestone karst around Antequera and the Sierra de Grazalema, and gypsum and evaporite deposits in the Tabernas Basin and Cabo de Gata. Soil distribution spans Fluvisols on river terraces of the Guadalquivir, Luvisols and Cambisols on rolling landscapes near Córdoba and Seville, Podzols and rankers in high Sierra Nevada and limestone-derived Rendzinas around Úbeda, while saline soils and solonchaks occur in marshes such as Doñana and saline depressions near Almería.

Hydrology and water resources

The Guadalquivir River is Andalusia's principal fluvial artery, with tributaries including the Genil, Guadalimar, and Guadiato draining major agricultural plains and feeding reservoirs such as Iznájar and El Tranco that support irrigation for estates near Écija and the Campiña. Atlantic catchments in Huelva and Cádiz comprise the Guadiana Menor and Piedras systems, while Mediterranean basins include the Guadalhorce, Vélez and Almanzora rivers subject to ephemeral flows and episodic flash floods impacting Almería and Málaga provinces. Water infrastructure includes reservoirs, aquifers like the Sierra Morena and Guadalquivir aquifers, inter-basin transfers historically affecting Málaga and Granada, desalination plants along the Alboran Sea coast near Almería, and management challenges linked to droughts, overextraction in the Guadalquivir valley and agreements affecting transboundary flows toward Portugal and the Strait of Gibraltar maritime zone.

Biogeography and ecosystems

Andalusia hosts ecoregions from Mediterranean woodlands and forests—dominated by holm oak and cork oak maquis in the Sierra de Grazalema, Montes de Málaga and Sierra Morena—to semi-desert scrub and halophytic communities in Cabo de Gata-Níjar and Tabernas Desert near Almería. Montane ecosystems in Sierra Nevada harbor endemic species, with alpine and subalpine assemblages on Mulhacén and Veleta supporting flora linked to the Betic endemism hotspot, while wetlands such as Doñana National Park, the Marismas del Guadalquivir and Punta Umbría host migratory waterfowl along flyways connecting to the Wadden Sea and Sahel. Coastal dune systems, Posidonia meadows in the Alboran Sea, and riparian galleries along the Genil, Guadalquivir and Guadiaro sustain biodiversity including Iberian lynx populations in Doñana and Andújar, griffon vulture colonies in Grazalema and migratory bottlenose dolphin records near the Strait.

Human geography and land use

Human geography in Andalusia reflects rural and urban contrasts with metropolitan hubs—Seville, Málaga, Granada, Córdoba, Cádiz, Almería and Jaén—anchoring economic regions characterized by olive groves in Jaén, citrus orchards near Vélez-Málaga and Almuñécar, intensive greenhouse agriculture in the Poniente Almeriense, and vineyard landscapes around Jerez and Montilla-Moriles. Land-use patterns include irrigated agriculture drawing on the Guadalquivir irrigation system and Acequia networks, forestry and cork harvesting in Cádiz and Málaga, mining legacies near Linares and the Riotinto district, and tourism-driven coastal urbanization along the Costa del Sol, Costa de la Luz and Costa Tropical with impacts on habitat fragmentation, urban sprawl in Marbella and Torremolinos, and pressures on water and land resources that interface with policies from the Junta de Andalucía and spatial planning linked to EU cohesion funds and Natura 2000 designations.

Protected areas and environmental management

Protected area networks combine national parks such as Sierra Nevada National Park and Doñana National Park, natural parks like Cabo de Gata-Níjar, Sierra de Grazalema and Sierra de las Nieves, biosphere reserves including Doñana and the Alcornocales, and numerous nature reserves and protected landscapes across provinces. Management involves coordination among the Junta de Andalucía, Spanish Ministry for the Ecological Transition, UNESCO biosphere frameworks, Ramsar wetland designations for Doñana and Marismas del Guadalquivir, and EU Natura 2000 sites around the Strait of Gibraltar and the Alboran Sea, addressing conservation of Iberian lynx recovery programs, invasive species control, wildfire management in Sierra Morena and Grazalema, and restoration efforts in mining-impacted zones like Riotinto and Linares.
