“…The ability of the peat to store water has decreased over time as it has become more degraded. The lowest groundwater level in 2013-2014 was 30.6 cm below the peat surface [32], while in 2020-2021 we found the lowest level to be 44.0 cm below the peat surface (Figure 1). Fluctuations in groundwater level are also influenced by land cover and peat soil conditions.…”

Peatlands support the daily needs of people in many villages in Indonesia, including in Central Kalimantan Province. They provide the natural resources to enable fisheries, agriculture, plantations, and forestry. However, peatland utilization comes with various challenges, including fire, soil acidity, inundation, low fertility, and limited choice of suitable species. Many of the current uses of peatland can result in its degradation, oxidation, and increased risk of peat fire. Avoiding further environmental degradation will require the development of new technology that allows the community to both earn a livelihood and protect the peatland. In this study we assessed a range of technologies applied by 14 farmers at Tumbang Nusa village, Central Kalimantan province, in managing degraded peatlands in their home yard for agricultural business. The study shows that for endemic peatland species, good success can be achieved if they are planted directly. However, for species endemic to mineral land, there are four technologies applied by farmers in managing degraded peatland. The choice of technologies is influenced by their economic capacity/cash flow flexibility and their understanding of peatlands. Technologies intended to adapt to land inundation include the use of polybags, development of raised beds, and making peat mounds with mineral soil in the centre. Technologies to address the acidity and soil fertility include amelioration with dolomite lime and fertilizer. The use of polybags filled with peat soil is the easiest technology to adopt and can be conducted by all family members. However, a farmer’s choice of technology needs to always consider the potential environmental impacts in addition to increasing soil fertility so that peat conservation is maintained.

“…Rachmanadi, et al [154] explored the potential for natural regeneration in peat swamp forests by looking at wildlings, seed rain and the soil seed bank at sites with different levels of ecosystem damage. They found that the species number, the number of individuals and the diversity of wildlings tended to decline with distance from the forest and with increasing damage.…”

Tropical peatlands are fragile ecosystems with an important role in conserving biodiversity, water quality and availability, preventing floods, soil intrusion, erosion and sedimentation, and providing a livelihood for people. However, due to illegal logging, fire and conversion into other land use, the peatlands in Indonesia are under serious threat. Efforts to restore Indonesia’s tropical peatlands have been accelerated by the establishment of the Peatland Restoration Agency in early 2016. The restoration action policy includes the rewetting, revegetation and revitalisation of local livelihood (known as the 3Rs). This paper summarises the regulatory, institutional and planning aspects of peatland restoration, in addition to the implementation of the 3Rs in Indonesia, including failures, success stories, and the criteria and indicators for the success of peatland restoration.

“…Consequently, the recovery processes of the area will not success without human intervention from parties. Assisted regeneration is needed to accelerate the regeneration (Rachmanadi et al, 2017). The native tree species that potentially recommended to be used in restoration such as jelutung (Dyera polyphylla), pulai (Alstonia pneumatophora), kempas (Kompassia malaccensis), terentang (Campnosperma sp.…”

“…is known as pioneer species that will facilitate other species to ocupied the degraded area. The potential for regeneration is a biological legacy that determines the direction of regeneration of degraded peat swamp forests; in this case, the dominance of pioneer species should be the concern if their dominance can inhibit the presence of the following seral type(Rachmanadi Faridah, Sumardi & van der Meer, 2017).…”

This study examines natural regeneration of tropical peat swamp forest after fire. This regeneration information provides useful indications for restoration options, which could be done by assisted natural regeneration. The study area is located in Merang Peat Swamp Forest (PSF) in Musi Banyuasin District. Merang PSF is situated over a large peat dome that stores huge amount of carbon. 23 sample plots were established in the area burned in 2015. The regeneration of understorey, seedlings, and saplings was recorded in each plot. Meanwhile, peat depth and its maturity were identified to determine the soil characteristic of study area. After 3 years of fire, the area already covers densely by understorey mainly pakis udang (Stenochlaena palustris), pakis tanah (Nephrolepis exaltata), and resam (Gleichenia linearis) with depth of root zone reach about 40 cm in some plots. The native peat swamp species showed minimal regeneration during third years after fire due to understorey covering and limited number of surviving trees. The natural regeneration of woody species was dominated by bangun-bangun (Melicope glabra) and sepongol (Evodia sambuciana) which were calculated about 371 saplings/ha and 200 saplings/ha respectively. Those all two species also founded in the seedlings stage. The peat depth varied from 0.32 m to 4.71 m with peat maturity is dominantly hemic in the subsurface.
