The role of urban agriculture in facing the food crisis

Abstract

Urban agriculture has a role in dealing with climate change, one of the factors causing the food crisis that has begun to be felt by most of the world’s people, including Indonesia. The role of urban agriculture is considered to be able to provide food for urban and suburban/peri-urban communities through urban agricultural technology innovations that have developed in the community. This paper aims to provide an overview of the development of urban agriculture in Jakarta, Indonesia, as well as the prospects of urban agricultural development in Indonesia. The article discusses some technologies developed to support urban agriculture, including hydroponic technology, vertical farming, aquaponics, wall gardens, vertiminaponics, foot-square, and container gardening. Urban agricultural technology that has been widely developed is also supported by advanced technology, like the cultivation of hydroponic systems based on Internet of Things (IoT) technology. Managing organic waste from agricultural products and other urban waste is very supportive in overcoming the shortage of much-needed fertilizer. Organic waste management supports circular economic activities with the five principles of refuse, reduce, reuse, recycle, and recovery. From this principle, waste generated from economic activities will always return to feedback and become raw material for other activities.
