“…Nevertheless, Acacia's are more susceptible to fire if the stem diameter is less than 10 cm [11] hence, with more new growths along the highway the higher chances of wildfires occurring. There has been attempts and plans by the Brunei Fire and Rescue Department official to create firebreaks especially along Seria-bypass where fire occur often [15], however there is no evidence that these plans are being attempted along Telisai-Lumut highway. Since forest fires usually takes place during dry season (February to April), this early detection of Acacia may help on alternative solutions through regeneration of the forest area [15], [16].…”

Invasive alien Acacia trees have become a serious environmental problem in Brunei Darussalam, spreading into the vulnerable heath and mixed dipterocarp forest ecosystem where it has started replacing the native flora and contributing to forest fire.In this work, we study the spread of Acacia trees by analyzing images taken by drones along a newly developed highway within the vicinity of Andulau Forest Reserve in Brunei Darussalam. Based on the analysis, we aim to understand the Acacia spread and its habitat preference, which will be a critical factor in planning the future roadmap to maintain a sustainable and healthy forest ecosystem, and safety from potential forest fires. The Unmanned Aerial Vehicles (UAVs) were utilized to capture high-resolution images along the Telisai-Lumut highway and were subsequently analyzed images using ArcGIS software, to map and study the Acacia's distribution and habitat preferences, which will aid in understanding of Acacia's rapid dispersion. Our preliminary results show highest Acacia density and numbers closer to the highway. The barren loose sandy soil combined with the open terrain limits local forest tree growth but seems to provide good habitat for Acacia trees. Our results suggest that the highway provides an important dispersal opportunity for Acacia trees, bringing them in direct proximity of an undisturbed forest reserve. This may increase the risk of spread of this species into the forest, and importantly, given the fire proneness of Acacia, may lead to wildfires that threaten the neighbouring forest reserve. Keeping vegetation short and removing Acacia's close to the highway may mitigate these risks. Efforts such as spreading awareness on Acacia's invasiveness, identification and removal of Acacia trees, habitat restoration projects and meticulous evaluation for any introduced species should be done.

Self-rated health and perceived environmental quality in Brunei Darussalam: a cross-sectional study

et al. 2022

ObjectivesThis paper examines the relationship between individuals’ perceptions of environmental quality and self-rated health (SRH) after controlling for dimensions of socioeconomic, demographic and healthy lifestyle variables.DesignA cross-sectional survey.SettingThe survey was conducted in Belait, an oil-rich and gas-rich district in Brunei Darussalam, from 17 October to 11 November 2019 and focused on the most populated subdistricts (Kuala Belait, Seria and Liang), where 97% of the people reside.ParticipantsA final sample of 1000 respondents aged 18 years and older were randomly selected from the population of the chosen subdistricts, with 95% CI and ±3 margin of error. Due to variable selection, only 673 respondents were available for analysis.Outcome measuresSRH was dichotomised into 1 for good health and 0 otherwise. Perceptions of environmental quality included perceptions of the natural environment (air quality, marine quality, water supply, noise and olfactory pollution) and the social environment (crime). χ2 and logistic regression models were used to assess the relationship between individuals’ perceived environmental quality and SRH.ResultsMost respondents perceived themselves with good SRH (72%). The adjusted logistic regression shows that perceptions of air quality (OR=2.20, 95% CI 1.15 to 4.22, p=0.018) and marine resources (OR=1.84, 95% CI 1.24 to 2.74, p=0.002) in their surrounding areas were significantly associated with good SRH. However, other environmental variables were insignificantly associated with SRH. Among the control variables, healthy lifestyle and employment had positive associations with good SRH (OR=3.89, 95% CI 1.96 to 7.71, p=0.000, for exercising 3–5 times a week; OR=1.72, 95% CI 1.09 to 2.71, p=0.021, for being employed). In addition, frequent physical exercise compensated for the negative health impact of environmental pollution.ConclusionsThis study suggests that environmental quality has an important role in SRH. However, a healthy lifestyle measured with frequency of physical exercise seems to compensate for the adverse environmental effects on SRH.

“…While some of these fires may have been accidentally caused due to the throwing away of cigarette butts by smokers (Shahriar et al ., 2019), a large number of them were proven to have been started on purpose. People may start fires out of frustration when roads become overgrown with vegetation, or to flush out animals for hunting.…”

Peat fires in Brunei Darussalam: considerations for ASEAN haze cooperation and emerging regional infrastructure development

This paper sheds light on the extent of the haze problem in Brunei Darussalam and on Brunei's unique position in contributing to the haze through fires occurring in disturbed parts of its peatlands. Brunei's peatland fires, which have their roots in infrastructure development, juxtapose drastically with the drivers of peat fires in other parts of southern Southeast Asia, which are mainly due to small‐ or large‐scale agriculture development. Our discussion highlights how Brunei's status as both a small state in ASEAN and a minor producer of smoke haze has resulted in Brunei remaining at the sidelines of haze diplomacy and cooperation at the ASEAN level. Further, the paper points out a lack of attention to the role of infrastructure development on peatlands in driving fires and haze in the country and how this is also increasingly becoming an issue in neighbouring countries, where massive infrastructure projects are underway, cutting through Borneo's peatlands.
