The expansion and industrialization of cities, reducing of the rural population, disappearance of agricultural lands and increasing of construction in them have caused factors such as the need for food and economic, ecological and environmental needs and in the same direction urgent need for more greenery felt in cities. But the main question is how to meet the aforementioned needs in industrialized and crowded cities. It seems that one of the ways to answer this problem is the targeted arrival of agriculture in the urban landscape.
Urban agriculture category refers to the process of producing any crops within the city or suburbs and can include food cultivation (vegetables, legumes, mushrooms and even meat and dairy), medicinal plants, shrubs and ornamental plants. It also covers a variety of techniques and approaches, from backyard farming to Extensive urban gardening, hydroponic greenhouses and aquaculture.
Urban agriculture isn’t just horticulture in the city but also it considered as an important and basic component of many cities. Nutrition is one of the most important categories of urban human society due to its main role in life, health, culture and environment.
Urban agriculture is one of the sources of urban nutrition systems and it considered one of several food securities options for households. in addition to its merits and advantages, urban agriculture is facing obstacles. the study of restrictions and barriers to urban agricultural development indicates the wide range of restrictions and barriers to all economic, environmental, social, cultural, technical, institutional and service areas. Lack of legal, financial and educational support is one of the most important obstacles andlimitations of urban agricultural development. in other words, it can be said that as long as there is no place for urban agriculture in government planning, it will not be developed to provide services to citizens who interested in the field of agriculture. Also, when citizens are not sufficiently aware of the benefits and opportunities of urban agriculture and do not have sufficient knowledge and skills about the scientific principles of agriculture, they do not show a desire to carry out agricultural activities or after several failures in such activities, will no longer want to continue.
