DLR's mobile deployable plant cultivation unit (Mobil Entfaltbare PflanzenAnbaueinheit; MEPA) enables the production of fresh food during humanitarian emergencies. This image shows the simplest of a total of three cultivation systems. This ‘minimal system’ provides a seven-square-metre cultivation area and is designed to produce a yield of 85 heads of lettuce, weighing approximately 42 kilograms per harvest cycle. The MEPA system is based on hydroponics and is equipped with a solar-powered automated support unit.
