The role of urban agriculture in increasing agricultural productivity and food security

Today, the world is facing several problems, including population growth, urbanization, food demand increasing, depletion of water resources, and environmental degradation. "Urban agriculture" as part of urban activities is an opportunity to make positive changes in the world food system and produce quality food. Urban agriculture is a new solution to deal with environmental, social, and economic problems. It is obvious that with the expansion of cities and the growth of the urban population, the demand for food will increase. Agriculture has always been the main supplier of human food and creates food security for society. In addition to its advantages and disadvantages, urban agriculture also has its challenges. Cities are the main centers for achieving the goals of sustainable development, and therefore the production of quality food in the smallest place and in the shortest time is very important. By producing food on rooftops, backyards, and suitable urban areas and by applying proper management, the food needs of citizens can be answered and the quality of the urban environment can be maintained. It also provides an opportunity for low-income citizens to achieve food security by creating jobs and reducing household food costs. The present study is based on a descriptive and review method using library studies.
