Abstract:
A total of 22 million people and 17% of families in Sri Lanka are considered to be food insecure.
Malnutrition affects one-third of children under the age of five, while 40% of women are either
overweight or obese. Changes in the climate are the root cause of extreme weather. Both an
increasing population and crowded cities contribute to the occurrence of extreme weather events.
As a result of paving surfaces absorbing more solar energy than vegetation, temperatures can rise
by 6°C. Green architecture and more environmental consciousness are contributing to the
expansion of urban gardening. Within the urban residential zones of Sri Lanka, vertical green
spaces are preferable over horizontal ones due to the limited space available and the rising cost
of those places. It is possible for the construction industry to adopt environmentally friendly
building practices in order to address climate change, carbon emissions and concerns related to
resource utilization. Vertical farming is a method of planting crops in a vertical orientation by
using hanging pots or structures. This review examined the efficacy, environmental impact, and
socio-economic benefits of edible vertical gardening in urban areas to improve human health. The
direct benefits of edible vertical gardening include the cultivation of homegrown herbs and
vegetables that are organic and healthy. High levels of nutrients derived from herbs and
vegetables produced at home. There is a correlation between the presence of vertical gardens
and a reduction in the occurrence of several respiratory disorders, as well as Sick Building
Syndrome, cancer, stroke, and depression. Improve the indoor air quality, as well as urban
farming, social functions and urban physical relief, all increase. In addition to fostering selfsatisfaction,
vertical gardens also strengthen family and intergenerational bonds. Accreditation
from the National Green Building Council indicates that vertical gardening contributes to the
improvement of society. The provision of a sustainable lifestyle, food security and the
modernization of buildings is made available. Enhanced living circumstances, improved health
and ecological landscape restoration are all benefits of city facade gardening. There are numerous
advantages associated with vertical gardens, including environmental, economic, social,
psychological, aesthetic, and socioeconomic.
