How Can Farms With LED Lighting Help Produce Higher Yields?

As the world's urban population continues to grow, it is estimated that 68 percent of the world's population will live in cities by 2050.Demographic change will lead to increased demand for food within cities, putting pressure on agriculture and food systems, especially in developing countries.Urban agriculture has long been seen as an innovative part of the diversification of the food system.Fully operational urban farms around the world can produce up to 180 million metric tons of food a year, accounting for more than 10 percent of the world's total production of beans, roots and vegetable crops, a 2018 study of the potential of global urban agriculture found.Urban agriculture is rapidly becoming an integral part of the American agricultural system and is attracting investment in related development and research.Vertical farms are one area of investment.Vertical agriculture offers an innovative solution to meet the growing demand for fresh produce.The potential of vertical farming is to be able to grow crops vertically (mainly green leafy vegetables) in smaller indoor areas, reduce water use and grow them in a tightly controlled environment.Lighting technology plays an important role in the development of vertical agriculture and still needs to be developed.Traditional lighting technologies, such as high pressure sodium lamps, are not suitable for vertical farming in terms of size and radiant heat, and fluorescent tubes face obstacles in providing the lighting efficiency required for plant cultivation.Moreover, fluorescent tubes' dependence on mercury poses a danger to both crops and workers.These considerations have LED to LED becoming the preferred lighting solution for vertical farms.In addition to its compact size, leds also have a higher level of control over the nature of the light itself, which means that operators can perform different light treatments on their crops to maximize quality and yield, as well as flavor and nutritional value.Lighting now accounts for 30 per cent of vertical farm costs and 25-30 per cent of operating costs, which means there are still big opportunities for improvement.As LED efficiency improves, costs continue to fall, and "light recipes" help automate, lighting technology is helping speed up urban and vertical farming, bringing fresh produce closer to consumers and ensuring investment and warmth.Addressing the challenges of the urban future is a challenge in itself, but with the accumulation of research, recognition at the highest levels of government, and continued investment in innovative solutions, urban and vertical agriculture is bound to play an indispensable role in the agricultural system.With the continuous progress of urban agriculture and its technology, vertical farms are emerging in cities to bring fresh and nutritious food to people all over the country and even the world. This will become a reality in the future.
