The Tehuantepec Isthmus, a southern region of Mexico that includes the states of Oaxaca, Chiapas, Tabasco and Veracruz, holds the highest concentration of wind farms in Latin America.
The Isthmus, measuring a mere 200 kilometers between the Pacific Ocean and the Atlantic Ocean, is the third narrowest strip of land on the continent, following Nicaragua and the Panama Canal. A total of 28 wind farms have been planned for construction, 15 of which have already been completed.
The region is ideal for the construction of wind farms since high wind speeds are constant throughout the year. “The southern Andes converge at the Tehuantepec Isthmus, creating a kind of tunnel effect the same width as the land strip. This ensures that the winds gain great strength and reach a high velocity,” explains Patricia Mora, a research professor in coastal ecology and fisheries science at the Interdisciplinary Research Center for Comprehensive Regional Development, Oaxaca Unit (CIIDIR Oaxaca), at the National Institute of Technology.
An environmental impact study conducted by the URS Corporation Mexico at the request of Natural Gas Fenosa, which was used to justify the construction of the Biino Hioxo park in Juchitan de Zaragoza, Oaxaca, concluded that the development of a wind farm “in this area of the state of Oaxaca is a clear example of sustainable development” and that “the project is environmentally viable as it utilizes renewable resources and does not generate significant environmental impacts.”
But while environmental impact reports tend to support the construction of these wind farm parks, local communities and environmentalists are raising concerns that local flora and fauna are being affected. The cases of the Barra Santa Theresa in Alvaro Obregon and San Vicente Beach in Juchitán de Zaragoza are of particular interest.
“This is the meeting point of various intimately related aquatic and terrestrial ecosystems, known as ‘ecotones.’ What occurs in each distinct ecosystem affects the dynamic on a larger scale, placing the existence of the adjoining ecosystems in danger,” Mora said.
