Abstract

A study was conducted to compare the urban forest management in three urban forests in Samarinda City. The application of GIS (Geographic Information System) is one of the alternatives to conduct a variety of processes such as: providing geographical information system, identifying the areas of urban forests in Samarinda, helping to plan the process of map digitalization and performing overlay process. The main method used for the data analysis process on the map was the overlay process data analysis technique. The research findings showed that: 1) the appointment of urban forests as the initial step of urban forest development needed more implementation from the government; 2) the urban forest determination needed more socialization to the owner of the urban forest and the public in 1992 and 2019; 3) the urban forests needed more management. There were some similarities and differences in the management of urban forests in the three study locations. The similarities among the three locations were that the three locations had already met the minimum standards of one urban forest location even though there was still one location outside of these three locations which did not meet the minimum standard. The differences were in managing the urban forests. These differences indicated that the urban forest policy was not fully implemented in Samarinda City.

Abstract. Mahmud, Endayani S, Stefano A, Lakehu A, Mutakim, Wahyudi, Husodo SB, Moeljono S. 2025. Shifting cultivation and soil conservation strategies among Papuan communities, Indonesia. Asian J Agric 9: 671-682. Local Papuan communities in Indonesia, rely heavily on land resources for food security, yet shifting cultivation remains the dominant practice. This system, while traditional, often leads to soil nutrient depletion, reduced productivity, and increased deforestation. To understand the dynamics of local farming practices, this study applied interviews, surveys, and participatory approaches with farmers and community members. Findings reveal that short-term crops such as long beans, peanuts, cabbage, chilies, and sweet potatoes dominate cultivation, contributing to rapid soil fertility loss. In contrast, perennial crops such as Areca catechu, Musa paradisiaca, Nephelium lappaceum, and Artocarpus altilis are typically maintained in fixed plots without being shifted. To address soil degradation, the study proposes several conservation strategies. These include mulching to retain soil moisture, living fences and cover crops to minimize erosion, intercropping to diversify yields and improve nutrient cycling, and the integration of Multipurpose Tree Species (MPTS) and hedgerows to restore long-term soil fertility. Collectively, these measures can reduce the necessity for continuous land clearing and help communities move toward more sustainable sedentary agricultural systems. Beyond technical solutions, the research highlights the importance of strengthening community awareness about forest and soil conservation. Transitioning away from shifting cultivation not only improves land productivity but also contributes to broader ecological resilience. By adopting integrated conservation practices, Papuan farmers can secure food production, maintain forest ecosystems, and develop more sustainable livelihoods in harmony with their environment.
