The effects of agriculture on the environment are diverse, including air purification, water purification, flood prevention, water resource cultivation, soil loss prevention, and waste treatment. It functions as a mitigation of urban heat islandation, an atmospheric purification, and plays a role in bringing life into the city.
This is because urban agriculture plays a significant role in attracting not only crops but also various insects into the city and attracting elements of the city's natural ecosystem.
In addition, through urban agriculture, agricultural activities can be carried out on the natural ground of the city. Also urban agriculture plays a major role in water circulation and organic matter circulation in the soil, and it also has the effect of preventing floods by storing rainwater.
In addition, green areas generated by urban agriculture not only reduce CO2 and supply O2 through photosynthesis or breathing, but also release fresh and cool air, and have a great influence on alleviating the heat island phenomenon of the city hot with concrete and asphalt

  Strengthening bonds and forming a community through urban agriculture can also be seen as great advantages. It is true that in the current city, which has been pursuing only scale expansion, there are almost no cultural spaces, rest areas, or meeting places that can be enjoyed if there is no "money.“
Such a lack of natural space for people to meet leads to a lack of conversation or ties between people, which can lead to serious social pathologies.
If we talk a lot and form a community through frequent meetings between people through urban agriculture, we can expect social and ethical effects that can help individuals develop identity, learn how to get along with others, and develop easier ways to adapt to society.
However, on the contrary, if such a social structure is insufficient or disconnected, it may cause serious social problems
Urban agriculture is a space for community culture experiences that can solve these problems. In urban agriculture, anyone can cultivate and manage crops directly, thereby forming a sense of cooperation and bond.

  The increase in double-income couples has also led to a lack of time to face-to-face with their families, which leads to a lack of conversation or disconnection between families.
In addition, with the family crisis and parental indifference, adolescents cannot achieve stable growth and youth problems are increasing. However, as these teenagers participated in urban agriculture, the conversation time and the degree of understanding between families increased.
It is an opportunity for people who lack family time or conversation due to their daily lives and work life to actively form new human relationships with others and understand more about their families as they participate in gardening with their families

  Urban agriculture has various economic effects. Waste heat can be used, food waste can be used as compost, and rainwater and sewage can be recycled.
A large amount of food waste discharged from home is composted by itself and used as manure. For example, in the UK, sewage treated safely through a sewage treatment plant near London is used for nearby farmland of 10,000㎡.
There is also an economic effect through rooftop gardening. When the rooftop of the same building as the school is farmed, the saving of cooling and heating costs through the insulation effect reaches 16.6%.
In the summer above 30°C, the rooftop concrete surface approaches 50°C, and the lower part reaches 40°C. However, if plants are planted and used, the temperature on the rooftop surface is maintained at 26~27℃.

  In the educational field, it is difficult to educate consistently about the growth of crops. The main activity of urban agriculture is generally to plant crops and harvest them. Through these activities, the educational effect of ecological-oriented urban agriculture can be obtained.
The understanding and appreciation of plants and nature that can be obtained through direct cultivation and management can awaken the gratitude and importance of nature by itself without intentionally inspiring the environmental consciousness. It will contribute to many education, especially as a vivid field of ecological and natural learning for growing children.
Urban agriculture makes us aware of the importance of soil and know the change of seasons, revives our senses through nature observation activities, and provides scientific awareness. It also develops our ability to get close to people and helps us take pro-social actions. It makes us know the meaning of sweat through labor and the joy of harvest, and makes us feel the love for the cycle of the natural world and life
  On the other hand, participating in cultivation activities with children is not just a sweaty labor. It makes our children carrying our next future to know the true meaning of nature formed closely as an organism, to remind that our society with nature is a real life, and to know the wisdom of living in the world.
In addition, it can be said that it plays a role in awakening the providence of living as a group member, not as a life alone in a community group called society.

  In the process of economic growth, cities were places where population and industry were concentrated. The city is a place that provides opportunities for employment and status improvement for those who have moved to the city to overcome poverty and find jobs while living in rural areas. Also It made many people to enjoy a higher level of education or cultural life for their children's education.
Rest or leisure during this period was a limited and negative meaning that only those who had nothing to do or who succeeded could enjoy.
Rather, for the maintenance of livelihood and education of children, urban residents went through difficult and repetitive lives by living a devoted life without sparing their bodies Through the sacrificial efforts of the members, our society has become able to increase remarkable economic growth and unprecedented convenience in daily life.
However, life only for growth and success caused diseases and lack of exercise due to overwork, and the accumulation of physical and mental stress threatens the health of urban residents, and the quality of life of urban residents continues to deteriorate.
Recently, urban residents are gradually trying to escape from time-driven daily life and complex, desolate cities through reflection on a success-oriented lifestyle. Instead, urban residents have increased their desire to achieve mental rest and tension relief in a pleasant nature-friendly environment, and for this, various leisure activities are being pursued
In particular, urban agriculture is a leisure activity located within the city, where families can enjoy, relax and participate together, and feel the joy of cultivation and harvest

  After entering an aging society in 2000, in which the elderly population aged 65 or older accounted for more than 7%, the proportion of the elderly population is expected to surge and our society is expected to enter a super-aged society.. This is known to be much faster than any other countries suffering from the same problem.
Efforts to increase the birthrate and prevent the pace of progress in aging are important in preparing for the upcoming aging society
However, at the same time, concerns about how to deal with the elderly population must be concurrently taken care of. Until now, there has been a tendency that the elderly are not productive. However, institutionalizing urban agriculture to a certain level will allow the elderly to naturally participate in production activities, allowing the elderly to support themselves
This can solve the social problems of an aging society, and the economic cost of supporting the elderly and the psychological burden of the elderly and their children will also be reduced.
