Local Practices

Increased agricultural use of tropical peatlands has negative environmental effects. Drainage leads to landscape-wide degradation and fire risks. Livelihood strategies in peatland ecosystems have traditionally focused on transitions from riverbanks to peatland forests. Riparian ‘Kaleka’ agroforests with more than 100 years of history persist in the peatlands of Central Kalimantan (Indonesia), where large-scale open-field agricultural projects have dramatically failed. Our field study in a Dayak Ngaju village on the Kahayan river in the Pulang Pisau district involved characterizing land uses, surveying vegetation, measuring soil characteristics, and monitoring groundwater during a period of 16 months. We focused on how local practices and farmer knowledge compare with standard soil fertility (physical, chemical, biological) measurements to make meaningful assessments of risks and opportunities for sustainable land use within site-specific constraints. The Kaleka agroforests around a former settlement and sacred historical meaning are species-rich agroforests dominated by local fruit trees and rubber close to the riverbank. They function well with high wet-season groundwater tables (up to −15 cm) compatible with peatland restoration targets. Existing soil quality indices rate the soils, with low soil pH and high Alexch, as having low suitability for most annual crops, but active tree regeneration in Kaleka shows sustainability.

<p>Peatlands play an important role in the ecological and economic aspects. Peatlands degradation in various regions in Indonesia brings economic issues, especially for women. The involvement of women in the peatland restoration program as a strategy needs to be reviewed. This research focuses on the involvement of women in the peatland restoration as a village facilitator, mainly on aspects of economic revitalization. This research focuses in 3 Villages in Central Kalimantan Province, Jabiren Village, Tumpang Nusa Village, and Gandang Barat Village. The main question of this research is how are the actions, challenges, and strategies experienced by women as village facilitators in the Desa Peduli Gambut program. Based on in-depth interviews with relevant actors and literature studies, this research finds, 1) the economic revitalization program conducted by women village facilitators build the economic resilience of rural women communities and changes the gender relations; 2) women village facilitators faced structural and cultural obstacles in their action; 3) the program is also the part of political actions for peatlands preservation.</p>

Continued Use

If 150 years of continued use counts as a sustainability indicator, the river-bank agroforests in the peat landscapes of Central Kalimantan suggest solutions for current challenges. The 2015 fire season in Indonesian peatlands triggered a fire ban and peatland restoration response, prioritizing canal blocking and rewetting. However, sustainable livelihood options remain elusive. We report local ecological knowledge of soils and vegetation applied in land use choices in swiddens and agroforests in five Dayak Ngaju villages in Jabiren Raya and Kahayan Hilir subdistrict (Pulang Pisau, C. Kalimantan, Indonesia) on the banks of the Kahayan river and discuss impacts of fire-ban policies. Plots accessible from the river with no or shallow peat were traditionally preferred for swiddening, with various indicator plants and soil characteristics underpinning the choices. Without swiddening farmers depend on off-farm jobs and agroforests for income. More policy attention for non-peat riparian-zone agroforestry as part of peat landscape livelihood systems is warranted.

The regional tectonic conditions of the KSK Contract of Work are located in the mid-Tertiary magmatic arc (Carlile and Mitchell, 1994) which host a number of epithermal gold deposits (eg, Kelian, Indon, Muro) and significant prospects such as Muyup, Masupa Ria, Gunung Mas and Mirah. Copper-gold mineralization in the KSK Contract of Work is associated with a number of intrusions that have occupied the shallow-scale crust at the Mesozoic metamorphic intercellular junction to the south and continuously into the Lower Tertiary sediment toward the water. This intrusion is interpreted to be part of the Oligocene arc of Central Kalimantan (in Carlile and Mitchell 1994) Volcanic rocks and associated volcanoes are older than intrusions, possibly aged Cretaceous and exposed together with all three contacts (Carlile and Mitchell, 1994) some researchers contribute details about the geological and mineralogical background, and some papers for that are published for the Beruang Kanan region and beyond but no one can confirm the genesis type of the Beruang Kanan region The mineralization of the Beruang Kanan area is generally composed by high yields of epithermal sulphide mineralization. with Cu-Au mineralization This high epithermal sulphide deposition coats the upper part of the Cu-Au porphyry precipitate associated with mineralization processes that are generally controlled by the structure

This research used the lesser known species as much 5 types rattan, consisted of i.e marau (Calamus Mettanensis Becc), toho (Calamus Spp), galang (Daemonorops Verticilaris Griff Mart), hijau (Calamus Spp) and simpurut (Calamus Panajuga Becc) from Central Kalimantan. Preservative used the mixture of boric acid with the borax and copper-8 by  the concentration of 1,0 %, 2,0 % and 3,0 %. Soaked time during 2 day, 4 day and 6 day by immersion chilled. Result of research indicated that the retention value varied, the greater of concentration condensation and soaking period, the greater average the value of retention while penetration result at all of treatment showed the value 100 %.Keywords:  rattan, preservation, retention, penetration, cold soaking.
