Biofuels in Ecuador were born with the purpose of achieving an effective substitution of imports of petroleum derivatives. The objective of this research is to analyze the impact that biofuel production has on water, food, and energy, and its contribution to reducing the growing dependence on fossil fuels in the transportation sector in Ecuador. The analysis focuses on ethanol produced from sugar cane, which is used to produce Ecopaís gasoline. The methodology is composed of three parts. For the first part, Geographic Information Systems were used; for the second, the FAO Penman-Monteith method; and, finally, in the third, the energy consumption was obtained through secondary information. As a result, taking the year 2019 as a reference, ethanol became the ninth product with the largest amount of land suitable for agriculture, and the seventh with the most irrigated areas in a country that suffers from malnutrition. Countries with a tropical climate and highly dependent on imports of petroleum derivatives are tempted to implement policies to promote biofuels. However, due to the risks that this renewable fuel represents on food security, other options for reducing its energy dependence should be exhausted.

厄瓜多尔的生物燃料诞生的目的是实现对进口石油衍生物的有效替代。这项研究的目的是分析生物燃料生产对水、食物和能源的影响，以及它对减少厄瓜多尔交通部门对化石燃料日益增长的依赖的贡献。分析的重点是由甘蔗生产的乙醇，用于生产Ecopaís汽油。方法论由三部分组成。第一部分使用了地理信息系统；第二种，FAO Penman-Monteith 方法；最后，在第三个中，能源消耗是通过二次信息获得的。因此，以2019年为基准，乙醇成为我国适宜农业耕地面积第九大、灌溉面积第七大的产品。热带气候和高度依赖石油衍生物进口的国家很想实施促进生物燃料的政策。然而，由于这种可再生燃料对粮食安全构成的风险，应该用尽其他减少其能源依赖的选择。
