“…The improvement in burn date and reduction in associated uncertainty resulting from this study could prove useful for a variety of applications including those related to multisensor biomass burning inventories, associated air quality impact studies, temporallyconsistent emissions comparisons, fire early-warning systems, post-impact fire assessments, timing of drought impacts on fire, changes to fire regime patterns over time, and others (Prasad et al 2002;Palandjian et al 2009;Singh et al 2009;Kanabkaew and Oanh 2011;Reid et al 2013;Hayasaka et al 2014;Gibe and Cayetano 2017;Shi and Matsunaga 2017;van der Werf et al 2017;Z uñiga-V asquez et al 2017;Hayasaka and Sepriando 2018;Itahashi et al 2018;Koplitz et al 2018;Nguyen et al 2018). Some of these example studies rely upon dynamic atmospheric conditions which change from day-to-day such as wind speed and direction.…”

Wildland fires result in a unique signal detectable by multispectral remote sensing and synthetic aperture radar (SAR). However, in many regions, such as Southeast Asia, persistent cloud cover and aerosols temporarily obstruct multispectral satellite observations of burned area, including the MODIS MCD64A1 Burned Area Product (BAP). Multiple days between cloud free pre-and postburn MODIS observations result in burn date uncertainty. We incorporate cloud-penetrating, C-band SAR-with the MODIS MCD64A1 BAP in Southeast Asia, to exploit the strengths of each dataset to better estimate the burn date and reduce the potential burn date uncertainty range. We incorporate built-in quality control using MCD64A1 to reduce erroneous pixel updating. We test the method over part of Laos and Thailand during April 2016 and found average uncertainty reduction of 4.5 d, improving 15% of MCD64A1 pixels. A new BAP could improve monitoring temporal trends of wildland fires, air quality studies and monitoring post-fire vegetation dynamics.

“…From the results of the analysis, we can see that the PSI was above 600 g m -3 for two months in 2015 ( Figure 7a and result of Hayasaka & Sepriando, 2018). As a result of high particle concentrations, Palangka Raya is covered by dark fog and there are also indications that oxygen concentrations decrease when the haze peaks impact on human, but this needs to be evaluated with continued health research.…”

“…Further, there is evidence that a slice of forests near the Sebangau National Park in the part of the MRP disappeared in connection with the dense hotspots in 2006. The highest numbers of fire occurrence prior to 2018 in this province have been recorded in the years of El Niño (Putra & Hayasaka, 2011;Yulianti & Hayasaka, 2013;Hayasaka & Sepriando, 2018).…”

“…The concentration of particulate matter (PM10) in Palangka Raya (Central Kalimantan) in 2019 showed concentrations >2 000 µg m -3 (Hayasaka & Sepriando, 2018), which was far higher than in 2002 and 2006, about 2 000 µg m -3 (Hayasaka et al 2014). Since the safe limit for human health PM10 is <400 µg m -3 according to the technical guidelines for the calculation and reporting air pollution standard index of Indonesia, the air quality in Palangka Raya was very unhealthy conditions and increase the sensitivity of patients with asthma and bronchitis.…”

<p class="Abstract">fires in Indonesia. About thirty percent of the total fires are spread in Central Kalimantan Province. Symptoms of climate change in the form of increasingly frequent weather and extreme climate phenomena support the severity of forest and land fires which results in increased release of air pollution gases. In 2015, the peak fire months had emitted a high concentration of air pollutant gasses and causes hazardous air pollution. This study aims to investigate the latest severe fire occurrence and haze conditions in Central Kalimantan. Hotspot data was from 2006 to 2017, visibility data were from four times of El Niño event, Particle Matter Size 10 (PM 10) data and Pollution Standard Index (PSI) was from very strong El Niño in 2015 comparison to La Niña in 2016/2017. The results showed that the top incidents occurred not only very strong in 2015 but also weak El Niño in 2006. The most of dense hotspots density in the last twelve years (> 50% of fires in the area) found in peatlands in Pulang Pisau, Palangka Raya and Kapuas. Palangka Raya's case, dangerous of APSI with PM10 concentrations of more than 500 µg m-3 occurred for 2 (two) months, from the end of August to the early of November 2015. The maximum peak concentration of PM10 is as high as 3000 μg m-3, which is higher than other fire years. Based on the data obtained, the haze was blanketed Palangka Raya was getting thicker at the end of October. As a result, visibility is decreasingly limited, only around 200 to 900 m during the peak season and air pollution-related-peat fire. Thus, this severe condition could rose multiple effects, which will exacerbate climate change, environmental sustainability and the livelihoods of thousands of peoples.</p>

The climate crisis highlights the importance of forests in both mitigating and adapting to climate change, as well as in supporting the UN's Sustainable Development Goals (SDGs). To promote the better understanding and valuing of the critical role forests play, and to develop holistic approaches to protecting and maintaining them, the Center for International Forestry Research (CIFOR) has adopted the mission "to bring scientific knowledge to bear on major decisions affecting the world's tropical forests and the people who depend on them". This paper highlights an important topic in CIFOR's research portfolio -forests' diverse roles in climate change mitigation and adaptation and how forest governance ensures the equitable and sustainable wellbeing of people, both locally and globally. As one of the founding donor countries of CIFOR, the Government of Japan has consistently supported CIFOR's research through Japanese scientists collaborating in research projects and/or serving as members of CIFOR's Board. This paper, therefore, specifically highlights research projects funded directly by the Government of Japan, in particular.
