Major studies in emergency decisions are focusing on how techno-rational approaches applied in early warning systems to produce an output; rarely explore its opponent, the naturalistic intervention, or how both paradigms function in a crisis decision process. This research aims to identify the actual process of emergency decision making in the context of natural hazard studies, whether it employs the techno-rational or purely naturalistic approach. A systematic review is adopted to assess papers in the period 2000-2018 within the ‘emergency decision making’ AND “natural disaster” keywords. Research finds a non-techno-rational paradigm that contributes to producing a decision outcome. Instead of categorizing it the naturalistic paradigm as named by the scholars, we labelled it a non-technological paradigm. It consists of two main instruments: individual and institutional interventions, that together with the techno-rational instrument develop an adaptive continuum behavior while operating in uncertainty condition in order to generate an effective evacuation order for vulnerable people.

By combining transportation energy use per capita for main, side, and weekend activities, this study explores the correlation between transportation energy consumption and urban form at a village scale. Conducted in Depok, a satellite city of the Jabodetabek metropolitan area, Indonesia, four different urban form variables were measured, including population density, land use mix, street connectivity, and public transportation range area. Four other socio-economic variables, i.e., private vehicle ownership, driving license ownership, job type, and monthly income, were also considered in the analysis. Data on individual energy consumption in the transportation sector was acquired through an online questionnaire. The results of correlation analysis and one-way analysis of variance highlighted three main findings related to transportation energy consumption. First, the population density and the street connectivity were found to be correlated with the amount of transportation energy consumed. Second, the middle urban form compactness level outweighed the high compactness level in terms of energy consumption per capita per week. Finally, differences in private vehicle ownership, driving license ownership, and job type resulted in different transportation energy usage.

The Laigiang river basin in the South Central Coast of Vietnam plays an important role in the socio-economic development of Binhdinh Province. In recent decades, the region has experienced commonly flooding in vast areas. This research aims to simulate event-based rainfall-runoff modelling, a historical flood event in December 2016, by applying the HEC-HMS model and rainfall data from CHIRPS. The CHIRPS data is an acceptable potential data input of the hydrology model. These have been confirmed through reliable validation indexes: The peak flood flow rate of 2,542.6 m3/s corresponds to the flood frequency of 5%; NSE with the value at 0.95; R2 coefficient reached 0.87; PBIAS being around 0.45, and PFC being at 0.89. It shows better performance in the rainy season than in the dry season. Inclusive, the CHIRPS rainfall data set and the HEC model could be used for some operational purposes in weather forecasting, especially for flood warnings in river basins in the South Central Coast, Vietnam.

One of the essential services provided by mangroves is carbon sequestration, and therefore climate change mitigation. While previous assessments of mangrove carbon stocks and sequestrations have focused on the estuarine and deltaic mangrove setting, there are still limited studies carried out at small island mangroves. The study aims to assess mangrove biomass carbon stocks in Pannikiang, a small island in South Sulawesi, Indonesia, which occupies 91.64 ha of species-rich pristine mangrove forests. A field-based data collection survey was performed using a circular plot approach, while above-ground tree carbon (AGC) and below-ground root carbon (BGC) stocks were estimated using available species-specific allometric equations. The mean AGC and BGC were 5.34 ± 0.17 and 1.68 ± 0.04 Mg C ha-1, respectively. Bruguiera gymnorrhiza mangrove species stored the greatest of carbon stocks, followed by Scyphiphora hydrophyllacea. Carbon stocks obtained from small island mangroves in this study were lower than stocks assessed from other mangrove locations across Indonesia and Southeast Asia. However, historical rates of deforestation in Pannikiang Island may generate emissions to approximately 82.17 Mg CO2-eq. Findings from this study will be beneficial in providing baseline data for policy decision-making on climate change mitigation in the region, specifically for improved land use management via a low carbon development agenda.
红树林提供的基本服务之一是碳固存，从而缓解气候变化。尽管之前对红树林碳储量和固存的评估侧重于河口和三角洲红树林环境，但对小岛屿红树林的研究仍然有限。这项研究旨在评估印度尼西亚南苏拉威西岛的小岛潘尼江的红树林生物量碳储量，该岛拥有91.64公顷物种丰富的原始红树林。使用圆形图方法进行了基于实地的数据收集调查，同时使用可用的物种特异性异速生长方程估计地上树碳（AGC）和地下根碳（BGC）存量。平均AGC和BGC分别为5.34±0.17和1.68±0.04 Mg C ha-1。Bruguiera gymnorrhiza红树林物种储存的碳储量最大，其次是水藻Scyphiphora hydrophyllacea。本研究中从小岛屿红树林获得的碳储量低于从印度尼西亚和东南亚其他红树林地区评估的碳储量。然而，盘泥江岛的历史毁林率可能产生约82.17 Mg CO2-eq的排放量。这项研究的结果将有助于为该地区缓解气候变化的政策决策提供基线数据，特别是通过低碳发展议程改善土地利用管理。

Coal mining and palm oil plantations are important sectors for supporting development in Indonesia. However, these sectors are criticized as the cause of horizontal conflicts, deforestation, and natural disasters that threaten the human security of local communities. This paper aims to compare the extent to which coal mining industries and palm oil plantations have impacted the human security of local communities. For this purpose, this study applies comparative process tracing in the case of Kalimantan Timur and Kalimantan Tengah. This research found that palm oil plantations have lower negative impacts on the human security of local communities than coal mining industries. Mining has co-opted the livelihood of local communities. Local communities, most of whom initially work as farmers, lose job opportunities due to the transfer of agriculture to mining, which does not fit with the agency of local communities. In contrast, palm oil plantations establish cooperation with local laborers and local farmers in the Nucleus Estate Smallholder scheme (NES) which prevents unemployment. Therefore, in the context of local communities’ human security, it is better for government to develop palm oil plantations than coal mining.

Studying Singapore Strait waters condition as a form of maritime mitigation is necessary because it is an international shipping lane. The dominant weather changes include rainfall, wind flows, and sea surface temperature (SST). This study aims to reveal the relationship between rainfall and SST activity in the Singapore Strait for over 18 years, from 2002 to 2019. The results showed a negative correlation, where the SST decreases as rainfall increases and vice versa. In addition, the high rainfall and low SST distribution occur in the Western season (December–February). The low rainfall intensity and high (warm) SST distribution occur yearly in the transition from West to East (March–August). Also, the distribution pattern is influenced by rainfall intensity and the water mass from the South China Sea and the Malacca Strait, where the strait is a mixture of these masses. The neural network model confirmed the negative correlation. Hence a small change in SST causes rainfall if it is cooler, and less precipitation if warmer.

In 2019, Labuan Bajo was designated a super-priority tourism destination, but this area is prone to earthquakes and tsunamis. The potential threats of disasters need to be considered when developing the tourism sector. Therefore, this study aims to determine the height and arrival time of tsunami waves based on a worst hypothetical scenario on the north coast of Labuan Bajo and its surroundings. The method used was numerical modelling with open source software TUNAMI F1, which calculated the wave propagation based on linear equations in spherical coordinates based on worst scenarios. The results showed that the Flores back-arc thrust earthquake caused a reasonably high tsunami with a fast arrival time at Labuan Bajo. The wave height of the tsunami around Labuan Bajo, Rinca, and Komodo Island is at least 3 m, but it reaches 8-9 m under certain conditions. Furthermore, its arrival time on the coast of Labuan Bajo is less than 2.5 minutes. This is much faster than those in Aceh (2004), Pangandaran (2006), and Palu (2018). Even though the early warning came 5 minutes after the earthquake, a high level of preparation and awareness is required to create a disaster-resilient tourist area in Labuan Bajo.

The Atlantic Forest is the most fragmented and threatened domain in Brazil. The main remnants are in the coastal regions. This paper describes a study performed at a protected federal reserve in Brazil located in western of São Paulo state, which is a transition with the Savannah. A forestry survey was made for understanding the forest structure, diversity, and floristic composition of an inland Atlantic Forest area. A total of 3,181 individuals with a Diameter at Breast Height over 3.5 cm were sampled. The data sample was composed of 29 families and 64 species from 15 plots. Forty-seven percent of the species were classified as a pioneer, 42% as secondary, and 11% as climax. The species Eugenia uniflora presented the highest importance value index. The values of Shannon-Weaver diversity and Pielou equitability index indicate the area has less diversity than others in the same phytophysiognomy and was dominated by a few species with many individuals. Several anthropogenic disturbances altered the forest cover of the Ponte Branca Forest remnant, which is in the process of secondary succession.

Telukjambe Barat and Telukjambe Timur Sub-Districts, Karawang Regency, have a high flood risk level due to changes in Land Use/Land Cover and the yearly occurrence of runoff water discharge. This research aims to analyze the rate and pattern of land-use change due to industrial development, examine the correlation of flood impacts with environmental-socio-economic factors, and develop a flood risk model in industrial areas. Data were collected through methods of system dynamics, remote sensing, geographic information system, questionnaire distribution, focus group discussions, and in-depth interviews with stakeholders. The results showed that floods in this regency are due to massive inland changes, such as the transition from vegetation and water bodies to industrial and residential areas and a strong relationship between environmental-social-economic factors. In other cases, areas with urban land conversion are likely to be flood-prone zones in places such as the Philippines, Belgium, and China. Based on the correlation test that has been conducted, the relationship with the highest level of closeness is the correlation between environmental factors and the impact of flooding, which has a value of 0.791. Therefore, the disaster risk model with an integrated spatial plan approach and an ecological perspective is an option for realizing sustainable development in industrial areas in Karawang Regency.

The study reveals the status of waste pickers, their livelihood asset profile and the vulnerability due to climatic and anthropogenic factors. It considered the independent waste pickers of Dhaka City, known as Tokai, who collect waste, especially recyclable and reusable materials. Using semi-structured interviews and personal histories, two groups of participants were explored qualitatively: independent waste pickers and other stakeholders. Waste-picking is sometimes the first source of income for persons displaced to Dhaka as a result of human and non-human changes. While most were homeless sheltering anywhere they could, they made a valuable contribution to the recycling industry and to improving environment and ensuring others' well-being, filling a gap left by councils failing to collect the waste produced daily by residents and industry. However, their efforts are largely unrecognized, and their labour stigmatized. Consequently, they have far less access to health, education, credit and utilities. Moreover, poverty and lack of family guidance may make them vulnerable to pursuing involvement in ill-advised political activism. The study concludes that the government and others need to shape a policy that takes into account the livelihood and survival needs of waste pickers and strive to ensure the provision of decent work within this sector and recognition of their societal contribution.
