Abstract

Abstract. Astiani D, Taherzadeh MJ, Gusmayanti E, Widiastuti T, Burhanuddin. 2019. Local knowledge on landscape sustainable-hydrological management reduces soil CO2 emission, fire risk and biomass loss in West Kalimantan Peatland, Indonesia. Biodiversitas 20: 725-731.  Local knowledge in managing peatlands, especially in the area of peat hydrology, has been practiced through generations to manage peatlands for agriculture and small scale gardens. Farmers in West Kalimantan have developed the way to conserve water by making simple dams using soil or woody plants to hold water from the peat upstream areas on small channels or rivers. To reduce puddles during rain or tides, people make small trenches, so-called parit cacing in the middle of the larger channel. The trench cross-section size is ~30-40 cm2. This channel can maintain the peat water level to the extent of the depth of the channel. These channels, at the same time, are useful, for a clear, easy land ownership border for one farmer family land. The results of CO2 emissions assessment at various water levels on the peatland landscape demonstrate that the landscape which surrounded by the parit cacing trenches can maintain lower CO2 emissions compared to the one that has deeper water levels. The knowledge to develop this channel has also reduced the risk of peatland fire hazard and the amount of peat biomass loss on a fire event. An assessment on the effect of water level on the loss of peat biomass when burned, reduce 30-78% loss risks if compared to water table depth of 60-80cm, which is assumed as general practices on peatland recently. The practices of the knowledge on peatlands hydrology management can reduce the risk of peatland soil CO2 emission as well as loss of peat mass through decomposition and during peat fires.

Abstract. Astiani D, Burhanuddin, Taherdjadeh M, Curran LM. 2016. Effects of water table level on soil CO2 respiration in West Kalimantan forested and bare peatland: An experimental stage. Nusantara Bioscience 8: 201-206. Peatland forest is one of ecosystems that are susceptible to the alterations of water regimes. Our previous study demonstrated that hydrologic conditions are predominant variables in determining carbon respiration rates from peat soils. However, we have limited empirical measures of how hydrologic conditions (i.e., soil water table) affect the carbon respirations. A study had been conducted to ascertain the effects of water table levels on soil CO2 respirations of West Kalimantan coastal forested and bare peatland. We simulated natural intact peat core condition by designing 25 of "a double bucket" water level experiment using 5 levels of water tables (0-40cm) and measure soil CO2 respiration at soil surfaces. Results showed that water table levels significantly affected soil CO2 respiration, as well as peat microclimate conditions. Results also demonstrated that forest canopy had significant effects on reducing peat CO2 respiration through its function in maintaining site-environment conditions compared to bare peatland site. This study reveals that it is important to maintain peatland water level close to peat surface and to maintain forest/vegetation covered on peatlands to reduce soil CO2 emissions.
