0 -> When talking about life in a big city, many people think of the colorful nightlife, fancy attractions and endless new places to eat.
8 -> But did you know that several hundred million people in metropolitan cities around the world suffer from poor food security?
16 -> Even in Bangkok, the majority of the population spends over 40% a month on food that does not have sufficient nutritional value.
25 -> Urban farming is a key solution to solving this problem.
31 -> The two main types of urban farming are aeroponics and hydroponics.
39 -> Although both methods use soilless cultivation, there are some differences in how they work.
46 -> In aeroponics, crops are fed by periodically spraying their roots with water, minerals and fertilizer.
54 -> But in hydroponics, the roots of the plants are submerged in water to absorb nutrients.
59 -> These two methods can result in triple the production of planting crops in soil – sometimes up to 20 times as much.
65 -> These methods also use 90% less water…
69 -> … and allow plants to grow30 to 50% faster.
74 -> Furthermore, it is ideal for city inhabitants since these techniques allow for vertical farming, which uses 99% less space than traditional farming.
83 -> And, if crops are grown in a greenhouse, you can avoid unpredictable or severe weather.
89 -> Urban farming has attracted the interest of several countries throughout the world in recent years.
93 -> GrowUp Farms in London, England, for example, uses hydroponics to grow vegetables vertically and raises fish inside a pond underneath.
102 -> Meanwhile, Pasona, a Japanese recruitment agency, uses hydroponic technology to grow over 200 different varieties of vegetables at their office to use in cooking employee meals.
113 -> With urban farming's innovation and new, cutting-edge vegetable-growing techniques,the cities of the future can be less concerned about agricultural land depletion, which has a direct impact on food security.
