Environmental problems in a coal mining area affected by coal fires --A case study in Ruqigou Coalfield, Ningxia, China

Ruqigou Coalfield, being one of the most important coal mining areas in China, has suffered coal fire problems for more than one hundred years. Due to coal fires, about 4.513 million tons coal resources has been lost each year, and apart from a large volume of CO2 delivered into air, environmental problems such as land degradation, land pollution and air pollution are also produced. Air pollution, as one related to coal fires, is the most dangerous problems for local people and has already led to vegetation pollution in this area. Land degradation is mainly induced with occurrence of land subsidence, fissures with due to coal mining/coal fires, and debris slide/flow. With development of opencast coal mining, a large volume of waste was produced, which is the major source of land pollution. All these environmental problems are associated with coal mining or coal fires and their comprehensive effects are deterioration of environment.

A new type of infrared organ in the Australian "fire-beetle" Merimna atrata (Coleoptera: Buprestidae)

 The Australian buprestid beetle Merimna atrata (Coleoptera: Buprestidae) approaches forest fires because its larvae develop in freshly burnt wood. So far nothing is known about possible sensory systems enabling the beetles to detect fires and to cope with the thermal environment close to the flames. We found that M. atrata has two pairs of infrared (IR) organs on the ventrolateral sides of the abdomen. Each IR organ consists of a specialized IR-absorbing area which is innervated by one thermosensitive multipolar neuron. The primary dendritic branches ramify into more than 800 closely packed terminal endings which contain a large number of mitochondria. We called the special morphology of the dendritic region a terminal dendritic mass. The type of IR receptor found in M. atrata is unique in insects and can best be compared with the IR organs of boid snakes. Received: 14 August 2000 / Accepted in revised form: 18 October 2000     

2015年厄尔尼诺年东南亚主要国家活跃火发生类型与影响分析

2015年强厄尔尼诺引起东南亚干旱少雨与活跃火加剧,但目前有关活跃火时空特征、发生类型与强度及其对人口—社会经济影响仍分析不足。利用美国国家航空航天局火灾信息资源管理系统（FIRMS）VIIRS V1活跃火位置矢量产品,通过月际、地形、土地覆被类型等GIS分析确定东南亚主要国家活跃火主要类型,并评价各国活跃火对人口分布的影响范围与国别差异。结果表明：（1）东南亚2015年活跃火发生频次达81.40×10⁵次,中南半岛与马来群岛各占69.60%与30.40%,分别集中发生在2-4月与8-10月,各国活跃火频次与发生时间差异很大。（2）中南半岛五国活跃火地形差异明显,缅甸和越南活跃火集中分布于25 m以下;老挝（85~105 m、140~200 m）、泰国（5~15 m、70~110 m）和柬埔寨（5~15 m、70~110 m）活跃火随海拔呈双峰特征;马来群岛国家（印度尼西亚、马来西亚与菲律宾）活跃火集中分布于60 m以下的平原地带;且东南亚35%以上的活跃火均集中分布5~15°的斜坡。（3）东南亚森林、农田活跃火发生率为76%,其中森林活跃火发生率由柬埔寨的52.00%到老挝的74.27%不等,农田活跃火由老挝的13.18%到泰国的42.68%不等。（4）综合活跃火发生月份、海拔、坡度与覆被特征,可从山区刀耕火种农业与平原秸秆焚烧界定东南亚主要国家活跃火发生类型。（5）东南亚活跃火随人口密度增加呈先增后减至平稳变化的趋势,且多集中于人口稀少的乡村和原始森林,其中缅甸、泰国、越南三国有10%以上的活跃火发生在人口密度为72~91人/km²的区域,而马来西亚、老挝、柬埔寨、印度尼西亚30%以上的活跃火集中发生于人口密度在20人/km²以下的区域。     

History of equatorial vegetation fires and fire research in Southeast Asia before the 1997–98 episode: A reconstruction of creeping environmental changes

Charcoal fragments in forest soils give evidence of prehistoric and historic natural and anthropogenic wildfires in the equatorial rainforests and in seasonal monsoon forests of continental and insular South Asia. Conditions favourable for the occurrence of historic and contemporary rainforest fires are associated with droughts, especially during dry spells caused by the El Niño–Southern Oscillation (ENSO) event. Historic land-use fires and wildfires can be reconstructed from a number of narrative reports, including documents that reveal drought and famine. In the eastern part of Borneo prehistoric and historic records of coal fires reveal a unique natural source of wildfires. Starting with modern transmigration programs and systematic conversion of primary and secondary vegetation, including peat-swamp ecosystems, into farmland and industrial plantations, the use of fire as a land-clearing tool escalated in the 1990s. During droughts land-clearing fires additionally contribute to wildfires. A detailed study of the ecological consequences of the episode of land-use fires and wildfires of 1982–1983 was conducted on an area of 2.7 million ha of dipterocarp rainforest in East Kalimantan. The results show that dipterocarps are highly susceptible to fire and are replaced by pioneers and fire-tolerant species that occupy the disturbed sites or survive the immediate fire effects. Smoke from forest conversion burning caused considerable environmental problems, reducing visibility and affecting human health and security. Emissions from vegetation burning influence chemistry and functioning of the global atmosphere. The situation is different in those parts of mainland and insular Southeast Asia that are characterized by seasonal climate. Through long-term influence of climate variability, fire influence, and anthropogenic pressure the vegetation is better adapted to extrinsic stresses. During the 15 years between the extreme ENSO events and fire episodes of 1982–1983 and 1997–1998 the national and international communities have been alerted and prepared to respond to the escalating fire situation in Indonesia. The response to the onset of the 1997–1998 fire and smoke episode, however, was absolutely inadequate and erratic. Meanwhile a whole continent – the maritime continent of Southeast Asia – has been degraded by excessive fire application for more than 20 years.     

Indonesian peat and vegetation fire emissions: Study on factors influencing large-scale smoke haze pollution using a regional atmospheric chemistry model

Numerical modelling of fire-related smoke haze episodes in Southeast Asia is important for both prediction and assessment of atmospheric impacts, especially when observational data are fragmentary, as is the case in Indonesia. This work describes the atmospheric fate of smoke particles emitted during the 1997 Indonesian fires modelled with a regional atmospheric chemistry model. We established a new fire emission inventory and calculate that 55 teragram (Tg) of particulate matter and 1098 Tg of carbon were released during this fire episode. Our emission estimate is an intermediate value compared with other studies. Utilising different scenarios, we demonstrate the variable atmospheric impacts of surface vegetation fires and peat soil fires separately and also investigate the sensitivity of smoke dispersion to the differing meteorological conditions of an El Niño and a normal year. When peat fires are included in the emission inventory, modelled ambient particle concentrations exceed the ambient air quality standard across transboundary scales. In a scenario including only surface vegetation fires, ambient air quality standards are exceeded only in areas close to the main fires. This scenario demonstrates the prominent role of fires in peat areas in causing regional air pollution episodes. In years with normal meteorological conditions, intermittent precipitation and associated wet deposition during the dry season are predicted to remove most of the particulate emissions close to the sources. Strongly reduced rainfall and generally stronger southeasterly winds during El Niño years provide favourable conditions for larger scale smoke haze pollution.     

Climate anomalies, Indonesian vegetation fires and terrestrial carbon emissions

There was a widespread misconception about the causes of vegetation and land fires in Indonesia. At a certain point, the public perceived that fires and the associated haze pollution were primarily caused by smallholders' agricultural activities. In fact, there was a variety of land-use activities including large-scale land clearing following deforestation for further land development. El Niño events and the associated dry weather were sometimes quoted by officials and the media as the cause of fires. The fire episodes from 1980 to 2000 were analysed in connection with climate anomalies and the implementation of land-use policies related to forest conversions. The analysis employs long-term climatic and sea surface temperature data to reconstruct climate distributions and anomalies including Southern Oscillation Index (SOI), Sea Surface Temperature (SST) and Outgoing Long-wave Radiation (OLR). In this study, the terrestrial carbon emissions from vegetation fires were estimated based on official statistical data on area burnt. The possible incentives for sustainable land management were discussed in the light of fire prevention. The underlying cause neglected in the discussion of Indonesian vegetation fires was forest and land development policy. Legitimated in the early 1980s, it drove massive forest conversions and the use of fires for land clearing. El Niño Southern Oscillation (ENSO) provided dry weather suitable for biomass burning and widespread fire, but it was hardly the cause of fires. The estimate of area burnt in the big fires in 1997 was about 11.6 Mha, resulting in carbon release of 1.45 Gt, equivalent to 0.73 ppmv of CO₂, or almost half the annual global atmospheric CO₂ growth. Based on the current carbon market price such emissions by the 1997 fire episode were worth around US$ 3.6 billion.
