The increasing demand for food in urban areas, coupled with the challenges of limited arable land and climate change, necessitates the development of innovative agricultural practices. Hydroponics, a soil-less farming method, is a promising solution for urban farming systems, providing high yields in limited spaces. Genome editing, particularly CRISPR/Cas9, offers the potential to enhance the nutrient efficiency of plants grown in hydroponic systems. This paper explores genome editing approaches to improve the nutrient efficiency of plants in hydroponic systems for urban farming. The research focuses on enhancing plant growth, optimizing nutrient absorption, and increasing overall crop yield while minimizing nutrient wastage. Genome editing techniques could enable the modification of genes responsible for nutrient uptake, enhancing the plant’s ability to thrive in controlled environments such as hydroponics. This approach holds the promise of reducing resource consumption in urban agriculture, making it more sustainable. The paper reviews current literature on genome editing in plants, examines its applications in hydroponic systems, and discusses future prospects. The integration of climate-smart horticulture practices with genome editing provides a sustainable approach to urban food production, further contributing to global food security.
