A model for islands and dry coastal areas

The entire island of Fuerteventura was declared a biosphere reserve in 2009. It is the most ancient of the Canary Islands, the most arid, Photo Gallery. It has a surface area of 1659 square kilometres, a population of 106,456 住民, and attracts 1.6 million tourists each year.
Water and energy are the key factors for the survival of the island and the maintenance of tourism as the main driver of the economy. Dependence on fossil energy has so far been absolute, representing an inadmissible risk for the future of the island.
生物圏保護区としての宣言以来、, the island of Fuerteventura set water self-sufficiency combined with renewable energy sources as a target to be achieved by 2020. Photo Gallery.
The wind energy – water desalination binomial
現在では天然の表面と、島の地下水資源は、単なるをカバーするだけで十分です 10% 需要の, 海水や汽水の淡水化から得られた残りが.
Partnership between wind farms and desalination plants has been the solution to reduce water dependence. The most important demonstration project has been carried out at Corralejo, in the north of the island. The project consists of a 1.7 MW wind farm for self consumption associated with a sea water desalination plant with a capacity to produce 4000 m3 of water per day. で 2012, the wind farm was able to supply 87.42% of the energy consumption of the desalination plant which supplies the whole tourist area of the north of the island, as well as nearby towns.

The public water company was also the promoter of the 10.7 MW wind farm of Cañada del Rio in the south of the island, built in 1994 and that is now being increased to 24 MW. Being them the owners of 60% of the wind farm, water price support has been possible in the last years, favouring social water consumption by reducing costs in the main desalination plant of the island.
バイオ燃料, water re-use, and fight against desertification
再生可能な水戦略は、バイオ燃料の生産と水循環を結ぶ. The University of La Laguna is in fact successfully developing a pilot project aiming at biofuels production in arid areas from Jatropha curcas Photo Gallery. プロジェクトはDisaのレノバブルズ会社によって資金を供給される. A great advantage of this project is the use of non-conventional water resources, such as desalinated water surplus and treated wastewater, for irrigation.
Preliminary results available on oil and biodiesel quality from Fuerteventura crops are really promising. This initiative is also being developed in the framework of the biosphere reserve’s actions related to the fight against desertification, taking advantage of this crop’s ability to fix soil against erosion, on an island classified of high risk. This is also a project where knowledge is transferred from the University to the productive sector, and that promotes public-private partnership, both being important aspects of the National Innovation Strategy and of the Fuerteventura Biosphere Reserve Action Plan.
Solar Ice for the fishermen

Energy consumption to maintain the fish cold for storage and distribution is a relevant part of fishermen communities’ cost structure. Fisheries located in coastal or island areas they have to rely on electricity and fresh water for their ice production process. 一方または両方の欠如は非常に一般的です.
The pilot project carried out at Morro Jable, in the south of Fuerteventura, uses a well known set of technologies (吸収式冷凍機, 太陽熱, 太陽光発電, and wind energy) 緑漁業ビジネスへ: 環境への影響を減少しながらパフォーマンスを向上させる. さらに, it improves water efficiency by innovating in the production of ice from sea water instead of fresh water, そのようなフエルテベントゥラなど乾燥地域で重要である.
Lessons learned and replicability
