By the year 2025, nearly 3.5 billion people in the world will have no water, including 900,000 from Djibouti. The economic losses caused by the 2000–2012 drought pushed the country to a state of disaster. This has devastated Djibouti’s economy and left millions hungry. This is due to the country’s inability to grow food and dependence on the food imports. The 5 US$ million granted by the WB was not able to reduce the hunger and prevent further increase in poverty and social unrest due to want of food and water. This paper provides a solution to create a self-sustainable society that can live above the current poverty line. The study was carried out based on field investigation and published literature. Desalination cost comparison between fossil fuel-based technology and renewable energy-based technology was carried out based on data from working plants. These data were used to analyse the cost-benefit ratio of fresh water generated from seawater and its use in securing food to the population. By developing the geothermal resources, the country can be lifted above the poverty line. What the country needs, to come out of this crisis, is fresh water supply. The country’s geothermal energy resource can generate 900 × 106 kWh of electricity. The electricity required to generate 1000 m3/day (10 × 106 kg/year) of fresh water from the sea is about 11 × 106 MWh. The cost of desalinated water through geothermal energy sources is 1.6 US$/m3 which is far less than the desalinated water generated through any other energy source. Billions of dollars given as aid for poverty alleviation can be utilized to develop geothermal power plants to provide permanent food security to the country. The rural population of Djibouti can improve their socio-economic status and secure food security and eradicate hunger through geothermal energy source. Local governments also should play an important role in advising the funding institutions to develop geothermal power projects to support agricultural activity and create employment to the rural population and support a sustainable society.

地热淡化以确保粮食安全：吉布提的案例研究

到2025年，世界上将有近35亿人没有水，其中90万人来自吉布提。2000-2012年干旱造成的经济损失使该国陷入灾难。这毁了吉布提的经济，使数百万人感到饥饿。这是由于该国无法种植粮食以及对粮食进口的依赖。世界银行提供的5百万美元无法减少饥饿，也无法防止由于缺乏食物和水而导致的贫困和社会动荡进一步加剧。本文提供了一个解决方案，以创建一个可以生活在当前贫困线以上的自我维持的社会。该研究是根据现场调查和公开的文献进行的。基于工作工厂的数据，对基于化石燃料的技术与基于可再生能源的技术之间的脱盐成本进行了比较。这些数据被用来分析从海水中产生的淡水的成本效益比，以及将其用于确保人口粮食安全的用途。通过开发地热资源，可以使该国摆脱贫困线。为了摆脱危机，该国需要的是淡水供应。该国的地热能资源可产生900×106 kWh的电力。从海上产生1000立方米/天（10×106千克/年）的淡水所需的电力约为11×106 MWh。通过地热能源生产的淡化水的成本为每立方米1.6美元，远低于通过任何其他能源产生的淡化水的成本。为减轻贫困而提供的数十亿美元可用于发展地热发电厂，为该国提供永久性粮食安全。吉布提农村人口可以通过地热能源改善其社会经济地位，确保粮食安全和消除饥饿。地方政府还应在建议供资机构发展地热发电项目方面发挥重要作用，以支持农业活动并为农村人口创造就业机会并支持可持续社会。
