Water Demand for Vertical Farming – Advantages and Challenges

The concept of vertical farming has been introduced to improve food safety and production, as well as using less water, land, and other natural resources. This project aims to explore the differences between water demand per unit of production of vertical farming and traditional farming, especially for lettuce. Besides, the various sources of water supply for vertical farming will be listed to see the costs for irrigation in these ways. The approach for the study is based on the BC water calculator and data analysis of local vertical farming lettuce production. Based on conclusions from the research above, advantages, limitations, and challenges of vertical farming can be shown through comparisons with traditional farming.
