“…In contrast to what Hirano et al (2014) found that mineral nutrition and peat bulk density increased, the results of this study showed that after nine months after burning, organic carbon and total nitrogen decreased but not for available phosphorus. This is understandable as the effects of combustion on the subsurface environment may vary, depending on the frequency of fire and the severity of the fire (Arief et al 2019). In conclusion, this study indicates that peat fires significantly changed the physical and chemical properties of peat soil over a long period of time.…”

Abstract. Astiani D, Widiastuti T, Latifah S, Simatupang D. 2020. Soil characteristics and CO2 emissions of ex-burnt peatland in Kubu Raya District, West Kalimantan, Indonesia. Biodiversitas 21: 3691-3698. West Kalimantan, Indonesia has a large extent of tropical peatland with total 1.74 million ha with only 44.5% of such areas remaining as peat forest, while the rests have been converted into plantations, agricultural lands, and shrubs. The conversion of peat forest often uses fires to clear the vegetation and is followed by building canal to drain the water. The lack of vegetation combined with drought soil trigger uncontrolled escaped fire, especially in the dry season or El-Nino events, which is likely to affect soil characteristics and emit carbon dioxide. The purpose of this study is to examine the changes in soil characteristics both physical and chemical properties and to investigate CO2 emissions from peat soil post-fire. As a comparison, similar parameters were also assessed in non-burnt sites. The results showed significant differences in some peat soil characters both physically and chemically between ex-burnt and non-burnt peatland. The ex-burnt site had higher pH, available phosphorus and C/N ratio than those in the non-burnt site. Conversely, the total nitrogen and carbon contents, and cation exchange capacity were lower which is likely due to leaching. Peat fires also impacted physical characteristics of the soil such as increasing soil bulk density, reducing soil water content, soil temperature, especially in wet conditions. Carbon dioxide emissions in the ex-burnt site were considered higher than non-burnt site. These results could be brought out as a part of baseline data in managing ex-burnt peatlands to maintain a balance between carbon output and input and efforts on preventing peatland fires from becoming continuous carbon sources.

The increasing threat of forest fires on a global scale is not only a matter of concern due to the potential harm they may cause to both human and animal life but also due to their significant role in exacerbating climate change. In light of these circumstances, one might inquire as to whether forest soil can self‐ignite and, if so, under what conditions and at what temperatures this phenomenon may occur. This question is being addressed in the German pilot “Fire science of wildfires and safety measures” of the EU project TREEADS, and the first results are presented below. The importance of basic research into the self‐ignition of forest soil cannot be underestimated, as it provides crucial knowledge to prevent forest fires and protect human and animal health. Furthermore, mitigating the occurrence of forest fires can also play a role in reducing greenhouse gas emissions, contributing to global efforts to combat climate change. The procedure of the hot storage test is an effective means of determining whether a material can self‐ignite. During the investigation of six soil samples, it was found that five of them were indeed capable of self‐ignition. In addition to determining whether the material ignites, the modified hot storage test also analyzed the resulting smoke gases and measured their concentration. The research question of whether regional forest soil is capable of self‐ignition can be answered with yes based on these initial tests. Further experiments are needed to determine if self‐ignition causes forest fires.

Porous ceramic fabrication using natural pore forming agents have received more and more attention in the past few years. However, researchers have encountered an issue with an inconsistent particle size, which led to uneven pore distribution. Considering waste material as pore forming agent, this research seeks to explore the potential application of wood sawdust in porous ceramic production. Moreover, the effects of wood sawdust weight percentage (wt.%) and firing temperature towards the physical and mechanical properties of porous ceramic will also be investigated. Porous ceramic was fabricated by introducing two different proportions of wood sawdust (10 and 20 wt.%) into China clay, followed by drying at 110°C and firing at 900°C. The characterization analyses were performed by means of Fourier Transform Infrared spectroscopy, water absorption, apparent porosity, bulk density, and X-Ray Diffraction. The results showed that the compressive strength appears to decrease as the composition of the waste wood sawdust increases. Relatively, the water absorption value increases as the wood sawdust incorporation increased. This is because more porosity formation is observed at a higher sawdust ratio, leading to a lower density of the ceramic.
