Introduction
As humanity sets its sights on Mars colonization, one of the most critical challenges we face is establishing a sustainable food supply for future Martian settlers. The harsh environment of the Red Planet, with its thin atmosphere, extreme temperatures, and high radiation levels, poses significant obstacles to traditional agriculture. However, recent advancements in vertical farming techniques and the utilization of ancient grains have opened up promising new avenues for Martian food production.
This case study examines the groundbreaking Vertical Ancient Grains Cultivation (VAGC) project, initiated in 2026 at the Mars Science City in Dubai. The project aimed to develop and test innovative methods for growing nutrient-dense ancient grains in controlled, vertical environments that could be replicated in future Martian habitats. By combining cutting-edge agricultural technology with the resilience and nutritional benefits of ancient grains, the VAGC project represents a significant step forward in our preparations for sustained human presence on Mars.
