Enhancing urban sustainability through energy-efficient hydroponic cultivation of medicinal plants
摘要
In the wake of burgeoning urbanization sweeping our cities, there's a pressing need for innovative solutions to address environmental sustainability and cater to the daily wellness needs of urban populations. The research evaluates hydroponic systems using self-assembly technology designed for daily use to grow seven pesticide-free medicinal plants including Costus pictus, Asparagus racemosus, Withania somnifera, Ocimum sanctum, Mentha sp., Rauvolfia serpentina, and Tinospora cordifolia. These systems, characterized by their low energy consumption and high efficiency, offer a sustainable alternative to conventional farming practices, ensuring a ready supply of fresh, pesticide-free medicinal herbs and contributing to reclaiming green spaces and bolstering biodiversity conservation efforts. Notably, with energy use of merely 1 unit per day, these systems are cost-effective, making them an economically viable choice for urban households and wellness centres seeking to cultivate their pesticide-free medicinal herbs. Moreover, significant increases in biomass production among the studied species, ranging from 18.41% to 43.30% under hydroponic cultivation compared to traditional soil-based methods, further accentuate the viability of self-assembled hydroponic systems. Embracing such innovative solutions promises to foster healthier, more sustainable urban environments, ushering in a greener future for urban plant cultivation and wellness initiatives.
