Growing vegetables on green roofs has gained popularity in recent years as a method of increasing agricultural sustainability in urban settings. (As urban agriculture has recently been revitalised, rooftop gardens are becoming increasingly significant. Vegetable crops may be grown on green roofs, which opens up possibilities for incorporating agriculture into urban areas. However, due to a number of obstacles that must be solved before widespread implementation, rooftop vegetable producing operations are now quite limited. Although intense green roof systems are regarded to be most ideal for vegetable production, vast systems likely have the highest potential for sustained productivity because most buildings have weight load constraints. As a result, it is believed that shallow-rooted vegetables, such as significant salad greens harvests, are best suited for wide systems due to their ability to produce a lot of food with minimal inputs. Urban populations may benefit from the food production that green roofs provide, and they also provide a special opportunity to grow food productively in areas that are generally underused. As human populations become increasingly urbanised and urban customers become keener to purchase local foods for their families, the use of alternative agricultural production methods, such as green roof technology, will become more important. Although growing food upon roofs is an essential component of making cities more liveable and sustainable, green roofs are not the only way to ensure cities have access to food security. They ought to be seen more as an addition to existing urban food production sources.
Green roofs on a large scale; rooftop gardens; sustainable agriculture; urban food security
As the population of Indian cities grows, so does the need for and expenditure on food. However, as agricultural land is converted to residential, commercial, or industrial usage, the resource is becoming scarce. As a result, it lowers the opportunity to cultivate more and diverse agricultural food items. Food contamination, such as the use of toxic chemical and inorganic fertiliser and pesticides to improve output, is spreading at an alarming rate. In this situation, starting a vegetable garden on the roof might be a plausible and probable answer to these concerns.) Rooftop vegetable growing can assist to fulfil food demand by providing fresh and hygienic vegetables, lowering family spending for purchasing veggies, and creating a healthy environment by improving air quality.
