Abstract

Fire on peatlands takes place not only in areas where preparation for cultivation is in progress, but also in areas that have been cultivated, such as for sago palm growing. One of the important factors that influence the vulnerability of cultivated peatlands to fire is the availability and amount of biomass fuel that easily catches fire, such as ferns, grasses, and broadleaved shrubs in their living as well as dead (litter) stages. The present study concerns the vulnerability of peatland utilized for sago growing by smallholders, focused in Tebing Tinggi Timur, Kepulauan Meranti District, Riau Province. The objectives of this study were to analyze the composition and assess the biomass of fire catchers in the sago palm plantation. Data collection was conducted in three locations in Kepau Baru Village. In each location, a 1000 m-long transect line was drawn and 10 sampling plots of 2 m x 2 m were established along the line with 100 m intervals. Results showed that total biomass of fire catchers in this growing system was averaged at 24681 kg/ha, in which the dead plant fraction was predominating (average at 17478 kg/ha or 70.81%) over the living plant fraction (in average 7203 kg/ha or 29.19%). The latter consisted of ferns that averaged at 2.191 kg/ha or 30.42%, grasses (20 kg/ha or 0.28%), non-woody broadleaved shrubs (581 kg/ha or 8.07%), and woody broadleaved shrubs (4411 kg/ha or 61.24%). The amount of fire catchers in relatively large quantities in this plantation system could magnify fire risk during drier months, especially during El-nino years.

Abstract

Burrowing fauna inhabiting the intertidal flats, such as certain crabs and mudskippers, are  biotic  component of intertidal ecosystem with a crucial ecological role. Their burrowing activity increases the porosity of intertidal substrates that promotes oxygenation, sediment dynamics, nutrient transport, and carbon storage. These positive contributions could however be disrupted by the degradation of their habitats as may be induced by coastal erosion. In the case of Bengkalis Island in Riau Province, Indonesia, coastal peatland erosion has generated a huge amount of peat debris that is eventually deposited on intertidal flats.  The present study has been conducted to explore burrowing crabs and mudskippers inhabiting the island’s intertidal flats most likely impacted by the deposition of peat debris. Two transect line, between the highest and the lowest tide, were made in two locations (Perepat Tunggal and Selat Baru). Observation were conducted along the transect line at interval of 5 m. Our inventory in two study locations, Perepat Tunggal and Selat Baru, has confirmed the presence of at least seven species of fiddler crabs (Austruca annulipes, Gelasimus vocans, Tubuca Bellator, T. coarctata, T. forcipata, T. paradussmieri, and T. rosea), one species of soldier crab (Dotilla myctiroides), and five species of mudskippers (Periopthalmodon schlosseri, Periophthalmus argentilineatus, P. chrysospilos, P. gracilis, P. variabilis. Our presentation shares the results in details and discusses how the disturbances induced by coastal peatland erosion might affect such fauna.Keywords: fiddler crabs, soldier crabs, mudskippers, peat debris deposition

Abstract

Friendly peatland utilization is often regarded as ‘difficult’, ‘adding new cost,” and ‘unfavorable’ to the cultivated crops. Such views appear to restrain farmers in general to adopt friendlier methods in utilizing peatlands. In response to the call for improving their practices farmers often demand proven peat-friendly but profittable practices. Therefore, convincing evidences, such as successful farmers with such practices as models, are needed. In one of villages in Siak regency, Riau Province, we encountered a farmer figure that is potentially promoted as a model in this regard. However, after evaluating what he really practiced, we found that some improvements were needed to make his practices truly peat friendlier. Our paper concerns the results of our interactions with this figure in order to improve the: (a) control of groundwater level; (b) prevention of peat decomposition; (c) prevention of peat subsidence; (d) reduction of carbon emission; (e) diversification of the farm’s products; (f) aesthetic value of the farm; and (g) promotion to potential visitors and market the farm’s products.

Abstract

Community engagement is often abruptly terminated as a project has to be officially ended following the termination of the fiscal year, which often leads to direct contact break off between project executors and their local counterparts. Consequently, a project initiated in the previous year may not persist in the following years. One strategy to cope with this problem is to use long-distance communication via handphone (HP) to continue the engagement of local counterparts. Our paper shares our experience as counterpart of Badan Restorasi Gambut (BRG) in engaging local communities carrying out peatland revegation in Bengkalis, Siak, and Kepulauan Meranti Regency of Riau. Revegetation was implemented as production and planting of natural forest tree seedlings. This paper evaluates the effectiveness of using long-distance communication for continuing our engagement in peatland revegetation. In our communications, technical and non-technical constraints of revegetation as well as the perceptions and expectations of our counterparts were discussed. We concluded, long-distance communication helps maintain “bonding” between project executors and their local counterparts, so that they do not feel left alone after a project has been formally terminated. Nevertheless, long-distance communication that is not accompanied with a real financial support to cover costs, eventually will not be sufficient.
