Global InformationRio Alamar information
Rio Alamar or Arroyo de Alamar is a river mainly in northern Baja California, Mexico with a small portion in California, United States. The riparian corridor that is the Alamar has a wooded area home to: riparian, aquatic and migratory birds, abundant species of fish, and amphibians.[1] The wildlife and natural vegetation in the Arroyo Alamar was historically a vital resource for fishing, bathing, and even drinking.[2] The stream is formed by the confluence of Cottonwood Creek and Tecate Creek a short distance north of the Mexico–United States border. It flows generally west for about 25 kilometres (16 mi) through the San Ysidro Mountains and the Tijuana urban area before joining with the Arroyo de las Palmas in central Tijuana, to form the Tijuana River. The Rio Alamar tributary makes up almost one third of the larger bi-national Tijuana River Watershed that spans approximately 1,750 square miles and impacts the lives of more than 1.4 million people.[2] The major tributary as part of the Tijuana River Estuary has been deemed one of the 21 wetlands of international importance by the RAMSAR Convention.[3]
The Rio Alamar and the Tijuana River's Watershed is threatened by pollution and is the site of active rehabilitation and environmental justice efforts that are combined with urban planning in this region. [4] The lack of proper planning and regulation that contaminated the flood plain has also induced binational collaborations due to the close proximity of the Arroyo to the United States.[5] The pollution and the environmental injustices that threaten the Rio Alamar are a result of many long-standing and deep-rooted factors including: transnational and national policies, prioritizing profit-based land use processes, industrial pollution, underdeveloped urban infrastructure in Tijuana, exponential population growth and migration, and stark division created by the U.S.-Mexico border.The stream is formed by the confluence of Cottonwood Creek and Tecate Creek a short distance north of the Mexico–United States border.
