Agroforestry system on peatlands in Pulau Hanaut, Kotawaringin Timur: A win-win solution to preserve peatland functions

Abstract

Abstract Agroforestry on peatlands in Pulau Hanaut sub-district of Kotawaringin Timur is an approach that combines agricultural crops with trees on peatlands. The location of this project is in Serambut and Babaung villages, Pulau Hanaut sub-district. Primary data were collected through Focus Group Discussions (FGD), interviews, and direct observation in the field, and secondary data were collected by studying the related documents that existed. All the data then were analyzed by qualitative descriptive analysis. This site has a peat depth of less than 50 cm and a maximum water table between -10 to -15 cm. Peatland is a unique ecosystem that requires specific considerations for agroforestry practices. Implementing proper water management techniques, such as controlled water levels and irrigation, can help maintain the hydrological balance. Tree species selection that are suitable for peatland conditions were chosen by the communities, such as fruit tree species, cashew nuts, and enrichment planting on the current coconut farm. In addition, fire prevention is also an important part of peatland management. Therefore, zero-burning and organic farming practices should be implemented. Implementing agroforestry on peatlands requires careful planning, considering the unique characteristics of peatland ecosystems, and the ecological, social, and economic aspects of the local community. Local stakeholders’ involvement in decision-making processes is highly recommended to ensure the success of agroforestry initiatives on peatlands in the sub-district, which is part of the Mentaya-Katingan Peat Hydrological Unit, Central Kalimantan.
