VertiGrow is a device that allows residents of slums to grow nutritional food by utilizing the vertical space along the sides of their houses or roofs, while at the same time cultivating community empowerment and entrepreneurship. Current solutions to the malnutrition crisis in slums are based largely on food aid, although there has been some attempt at spreading alternative forms of gardening. These initiatives, including sack gardens, garbage dump gardens, and keyhole gardens, require the user to provide a substantial amount of horizontal land, and are heavily dependent on resources like water and soil. VertiGrow is unique in that almost anyone can use it regardless of their land possessions, and it can be adjusted to meet specific space needs. It is modular and portable, so it can be broken down and transported easily (essential for highly mobile populations). It is also extremely conservative, ensuring that expenses related to water and soil will not prevent its use.
