Análisis retrospectivo de la duna costera El Socorro, Baja California, México

Abstract: La prospectiva ambiental permite proyectar escenarios futuros con el fin de tomar decisiones participativas; metodológicamente requiere de un análisis retrospectivo que permita dar explicación a la situación que interesa analizar. El objetivo de este artículo es hacer la retrospectiva de una duna costera ubicada en el ejido Nueva Odisea en Ensenada, Baja California; un ecosistema con valores contrapuestos: el de proveer arena con minerales valiosos y el de ser el hábitat con la mayor diversidad florística entr… Show more

“…For sand alone, a conservative estimate of the amount mined is 40 Gt per year [77], making it the second most-used natural material after water and the most mined material globally [78]. Furthermore, aggregates are not only involved in the construction of buildings and infrastructure; they are also immersed in screens and cell phones, among other technological products, and their demand is growing in the energy sector for hydraulic fracturing (or fracking) of hydrocarbons [79]. This huge extraction of aggregates cannot occur without environmental and social costs.…”

“…As demand grows, aggregates are extracted from surface deposits in rural or peri-urban areas. This mining increasingly competes for space with other land uses, such as agriculture, and affects greatly the way of life of the communities involved [79]. Finally, although aggregate operators often claim to rehabilitate the quarries once the exploitation is over, in truth they simply abandon old sites or fail to remediate the damages caused [87].…”
