Over the last 15 years, Mexico has registered a fast development of large-scale wind farms in the Isthmus of Tehuantepec, located in the south-western part of Oaxaca State. This region is considered to have 44,000 MW of wind power potential capacity with 33,200 MW suitable for commercial development. The territory comprises traditional lands of the Binnizá and Ikjoots groups (Zapotecos and Huaves in Spanish), most of them organized through communal land regimes and customary law. Indigenous communities in the area heavily depend on traditional livelihoods rooted to the territory, including fishing and farming activities. The Isthmus is also part of the Mesoamerican Biological Corridor and one of the largest migratory bird routes, making it a sensitive and controversial area for windmill siting. As of the beginning of 2015, the Wind Corridor in the Isthmus of Tehuantepec comprises more than 15 private wind power projects reaching an accumulated installed capacity of 2,077 MW. Most of these projects are intended to supply electricity to private companies, while the rest is destined to sell electricity for public distribution in urbanized areas of the country. Opposition towards wind farms in the Isthmus started in 1994 and has gained force as private projects have spread out over the territory. In this context, local organizations expanded through several political instances with the contribution of different external actors. Such groups claim that government and private companies have not made formal consultation processes to indigenous communities affected by windmills. They have also sued over illegal land leasing contracts and environmental impacts on construction and operation phases. Additionally, indigenous communities have made strong complaints against the privatization and dispossession processes over their lands and local resources.
