Exploring the evolving landscape: Urban horticulture cropping systems–trends and challenges
(Elsevier, 2024-03-01) Sashika, M.A.N; Gammanpila, H.W; Priyadarshani, S.V.G.N.
Urban horticulture cropping systems offer a promising solution for food security and sustainable agriculture in rapidly urbanizing areas. This paper explores their evolving landscape, emphasizing trends and challenges shaping their development and impact on urban environments. Vertical farming, rooftop gardens, hydroponics, aeroponics, Internet of Things (IoT), integration of optimized space, resources, and year-round cultivation are considered as key trends in urban horticulture. These innovations reflect the growing interest in sustainable urban agriculture and technology's role in boosting productivity and resilience. However, urban horticulture faces challenges that demand attention. Limited space requires creative land-use solutions, while soil quality and contamination concerns necessitate remediation strategies for crop safety. Similarly, access to water is crucial, driving the adoption of water-saving technologies. The urban heat island effect poses another challenge, urging heat stress mitigation for crop health. Zoning and regulations play a vital role, requiring supportive policies and secure land tenure. High costs must be managed with innovative financial approaches to ensure urban farming's viability. Finally, public perception and awareness play a critical role. Advocacy, education, and community engagement are vital to dispel misconceptions, garner support, and encourage involvement in urban horticulture. Even with challenges, urban horticulture helps to provide food for the growing population, creates business opportunities, and contributes to a greener environment for sustainable development.

Sustainable Farming in Soilless Culture Non-Circulating Kratky Method Using Fuzzy Logic Control and Measure Greenness
(2022-01) WANNIACHCHI, L. R; JAYAKODY, A
Organic horticulture and organic commodities have to face severe rivalry in today's economic environment. Even though there are several forms of home gardening, there is a need for a more organized and structured need has arisen. In horticultural, plants are planted on the water as a substitute for soil, it is feasible to achieve great efficiency although might be more suitable. Feeding the seedlings with the appropriate nutrients and hormones, as well as oxygen, is critical to the plant's vitality. The plant requires these chemicals and supplying them to the roots of plants would guarantee that the plant obtains the nutrients and oxygen it requires on a constant schedule. The system's strength is to give the plant the necessary oxygenation through the Air Roots of the seedlings being planted. The plant needs oxygen as well as nutrients from these root fibers as it grows over time, the amount of fiber required to extract oxygen will rise. The intensity of chlorophyll on the leaves can be determined by evaluating the quality of the plant and its nature. A more robust process is required considering urban expansion and human involvement is limited. To overcome these situations systems used to employ the latest IoT and microcontroller technologies. This study to control ecosystems introduce fuzzy logic controls and use a computer vision-based approach to computing plant greenness.
