The Guadalquivir Marshes (in Spanish: Marismas del Guadalquivir or simply Las Marismas) are a natural region of marshy lowlands on the lower Guadalquivir River.
The Las Marismas zone forms a large part of the province of Seville in Andalucia, Spain. The area includes parts of the municipalities of Isla Mayor, Los Palacios y Villafranca, La Puebla del Río, Utrera, Las Cabezas de San Juan and Lebrija.
History
Approximately two millennia ago the wetlands comprised a large lagoon and estuary, known as Lacus Ligustinus in Latin, leading to the Guadalquivir River mouth with some sand bars to the South. Over time the lake silted up, gradually transforming into marshland.[1]
The marquessate de las Marismas del Guadalquivir is a Spanish noble title named after the area; this noble title was created by Royal Decree of King Ferdinand VII in 1829 for Alejandro María Aguado y Ramírez de Estenoz.[2]
Nowadays the Guadalquivir wetland region's main economic activity is agriculture, specialising in the cultivation of rice. An area of about 400 km² is devoted to rice farming with an annual output of about 310,000 metric tonnes, equating to approximately 40% of Spain's rice production.
Protected area
The wetland zone acts as a buffer zone between the human settlements of the Guadalquivir region and Doñana National Park, a protected area of marshland, streams, and sand dunes. The National Park was established in 1969 as a nature reserve when the World Wildlife Fund joined forces with the Spanish Government to purchase a substantial part of the local wetlands in order to preserve them.[3]
