Urbanization is the process of increasing the population migrating to urban areas, and urban farming is a farming practice carried out within the city. Both concepts have significant impacts on urban life and the environment. This research aims to analyze the interrelation of the positive impacts of urban farming and the negative impacts of urbanization. The analysis focuses on food and environmental aspects as alternative problem-solving methods in the cities of Bandung, Denpasar, and Palembang. This research uses qualitative method. Data collection uses field interview techniques with 30 informants, as well as a review of several scientific articles, previous research results, and reports from data-providing agencies such as the Indonesian Central Bureau of Statistics. Data analysis used the Miles and Huberman Model, with the stages of reduction, display, and conclusion drawing. The results of the analysis show that there is an interrelation between the positive impacts of urban farming and the negative impacts of urbanization in the cities of Bandung, Denpasar, and Palembang. In terms of food aspect, urban farming can provide various types of easily accessible food for urban dwellers, such as vegetables, fruits, fisheries, and small-scale livestock. The food produced is relatively close to residential areas, so the quality is still fresh and healthy and the price is affordable as well. In the environmental aspect, urban farming can optimize the use of limited or vacant land in residential areas into productive land, such as for green spaces, farming activities, gardening, fisheries, and livestock. Other functions include enhancing the beauty of the environment, reducing household waste, and preserving organism biodiversity.

This research was conducted in Srigading and Gadingsari Villages, Samas District, Bantul Regency, the Special Region of Yogyakarta. Both of these villages were selected as the study area because of their high vulnerability to coastal erosion. This research aimed to analyse the physical, social, and economic vulnerability and the capacity of communities in both villages to deal with erosion in Samas Coast using primary and secondary database. According to the results of the physical and socioeconomic scenarios, Srigading has a high vulnerability level, whereas Gadingsari has a low vulnerability level. Meanwhile, the equal scenario results in the same spatial distribution of vulnerability as the aforementioned scenarios. This research also finds that the capacity, which was based on knowledge of coastal erosion and its risk reduction measures, is categorized as medium. This capacity level is shaped by the constantly improved preparedness as communities experience coastal erosions directly.

Banda Aceh was the most affected city by the 2004 Indian Ocean Tsunami. This city has grown rapidly because of disaster recovery activities. Therefore, this study aims to identify the types of urban physical growth in Banda Aceh City quantitatively from 2005 to 2019. The characteristics of growth were identified by integrating geographic information systems and remote sensing. The analysis showed that the main types of urban physical growth in the city were edge-expansion in 2005-2009 and infilling in 2009-2019. The percentage of spontaneous growth area was the lowest in both periods. The process of reconstruction and rehabilitation was considered to greatly affect the types of urban physical growth, where newly built-up areas were established close to the existing built-up areas. This also caused urban densification in a relatively short time. The process of urbanization had reached a stable stage in the city so that the surrounding suburbs have the potential to experience regional transformation. Overall, the approach used in this study resulted in a more objective understanding of identifying the urban physical growth characteristics for better urban planning.
