A flood is an event of an increase in water volume above the standard limit due to increased rainfall, rising sea levels, storms, and others that result in submerging an area. Floods are disasters that can cause damage and loss of property, disrupt community activities and even cause loss of life. The central defiance to rescue flood victims is choosing a safe route for flood victims to reach the evacuation site. To be able to choose a safe route for flood victims, a flood evacuation simulation is made.  Flood evacuation simulation is part of the game that has been created and aims to provide education about the weight of the obstacle that needs to be considered in selecting routes for flood victims. In this flood evacuation simulation, each road has obstacles. The method proposed for choosing safe routes for flood victims is the Fuzzy-based Analytical Hierarchy Process (Fuzzy AHP). The calculation of road route weight using the Fuzzy AHP method will produce the weight for each route. The smallest weight route shows the priority route and the safe route for flood victims to pass. In this case, the Fuzzy AHP method's calculation produces the lowest weight of 0.02347, which is achieved by route 5, the route passing through S-a-b-d-D. This route is a priority route that is safe for flood victims to pass through.

Rising Sea Level

Humans had been living side by side with threats that are affecting human life, such threat in the future is the rising sea level. Mainly caused by global warming that results in several phenomenon which affects the increasing water volume on earth, this gives land dwellers a threat of being submerged especially island dwellers that had less land area. This causes great loss for the dwellers such as losing a home and source of livelihood. Therefore the function that is correct is a floating island that adapts with the rising sea levels and sustainable with purpose of fulfilling the needs of this floating island without harming the environment and maintaining tourism aspect by designing main function of the island as a tourism island and floating residence. Keyword: future; floating island; residence; sea level; submerged; tourismAbstrakManusia hidup berdampingan dengan ancaman yang mempengaruhi keberlangsungan hidup manusia, salah satunya di masa depan adalah meningkatnya permukaan air laut. Dilatar belakangi pemanasan global yang menyebabkan beberapa fenomena alam dan berdampak pada meningkatnya volume air pada bumi, sehingga masyarakat penghuni daratan memiliki ancaman berupa tenggelamnya daratan khususnya penghuni pulau yang memiliki luas daratan lebih kecil. Ancaman ini mengakibatkan kerugian yang besar bagi penghuni yang dapat kehilangan tempat berhuni serta sumber mata pencaharian utama. Oleh karena itu fungsi yang tepat adalah sebuah proyek pulau apung yang beradaptasi dengan ketinggian permukaan air laut serta mengadaptasi konsep sustainable sehingga dapat memenuhi kebutuhan pulau tersebut tanpa merusak lingkungan serta mempertahankan aspek pariwisata dengan menjadikan fungsi utama pulau sebagai pulau pariwisata dan hunian mengapung.

Introduction: The National Railway Master Plan (RIPNAS), dated 2018, mentions that the railway network size and railway service capacity for using trains as the main means of transportation can be increased by reactivating non-operational routes and improving the condition of the existing routes. Methods: In our study, we propose the Fuzzy Analytic Hierarchy Process (Fuzzy AHP) method to determine the best option for the reactivated Madiun–Dopolo trace route in East Java, Indonesia. The data obtained were derived from questionnaires filled in by experts in the field. The model used six main criteria: land use, technical aspects, transportation node integration, social insecurity, disaster factors, and funding. Result and Discussion: The analysis reveals that the predominant route selection criterion chosen by the respondents was the Land Use (with a score of 0.25). The least significant Madiun–Dopolo route selection criterion was the Disaster Factors (0.07). Based on the results of weighting the criteria and aggregating the respondent alternatives, the trace route most commonly chosen by the respondents was the Alternative Trace Route (Trace Route 2), with a score of 0.698, while the Existing Trace Route (Trace Route 1) had a score of 0.302. The Alternative Trace Route is longer than the Existing Trace Route, but it will mostly pass through farming regions, which is assumed to create less social conflicts than in the case of Trace Route 1. This also automatically means that Trace Route 2 will need fewer funds in land acquisition.

Decisions usually involve the getting the best solution, selecting the suitable experiments, most appropriate judgments, taking the quality results etc., using some techniques.  Every decision making can be considered as the choice from the set of alternatives based on a set of criteria.  The fuzzy analytic hierarchy process is a multi-criteria decision making and is dealing with decision making problems through pairwise comparisons mode [10].  The weight vectors from this comparison model are obtained by using extent analysis method.  This paper concern with an alternate method of finding the weight vectors from the original fuzzy AHP decision model (moderate fuzzy AHP model), that has the same rank as obtained in original fuzzy AHP and ideal fuzzy AHP decision models.

The storm came on the night of 31 October. It was a full moon, and the tides were at their peak; the great rivers of eastern Bengal were flowing high and fast to the sea. In the early hours the inhabitants of the coast and islands were overtaken by an immense wave from the Bay of Bengal — a wall of water that reached a height of 40 feet in some places. The wave swept away everything in its path, drowning around 215,000 people. At least another 100,000 died in the cholera epidemic and famine that followed. It was the worst calamity of its kind in recorded history. Such events are often described as "natural disasters." This book turns that interpretation on its head, showing that the cyclone of 1876 was not simply a "natural" event, but one shaped by all-too-human patterns of exploitation and inequality — by divisions within Bengali society, and the enormous disparities of political and economic power that characterized British rule on the subcontinent. With Bangladesh facing rising sea levels and stronger, more frequent storms, there is every reason now to revisit this terrible calamity.

The furniture industry is growing to a great extent in Bangladesh. Many market researchers believe that the industry has enormous potentiality. However, the expansion of this industry may face complexities within a few years. Due to the wrong selection of facilities, many organizations failed to earn profit as expected. It also needs a large investment. Selecting a suitable place for a new facility is going to be the biggest question of upcoming years. This study aimed to analyze Bangladesh’s furniture industry, address the facility location problem, and provide a constructive solution to the decision-makers. In this study, seven criteria were considered: availability of raw materials, transportations, skilled labor, proximity to customers, energy availability, economic zone facility, and environmental impact, and five ideal locations or alternatives: Khulna, Chattogram, Bogura, Gazipur, and Manikganj. Thirty-four experts took part in the survey to analyze the significant criteria for selecting a furniture industry’s facility location and alternatives or potential locations for the facility. The Analytical Hierarchy Process (AHP) and Fuzzy AHP methods (FAHP), two MCDM techniques, were used to analyze the data set. A sensitivity analysis was done to determine the model’s robustness for any critical changes in the real world. The result showed that ‘energy availability is the most significant criterion to select a facility location for the furniture industry, where it got 35.1% criteria weight in AHP and 33.9% in FAHP. ‘Chattogram’ was selected as the most suitable place containing 33.74% normalized weight in AHP and 33.81% normalized weight in FAHP.

Global warming will have a significant impact on water resources within the 20 to 30-year planning period of many water projects. Arid and semi-arid regions such as Southern California are especially vulnerable to anticipated negative impacts of global warming on water resources. Long-range water facility planning must consider global climate change in the recommended mix of new facilities needed to meet future water requirements. The generally accepted impacts of global warming include increased temperature, rising sea levels, more frequent and severe floods and droughts, and a shift from snowfall to rain. Precipitation changes are more difficult to predict. For Southern California, these impacts will be especially severe on surface water supplies. Additionally, rising sea levels will exacerbate salt-water intrusion into freshwater and impact the quality of surface water supplies. Integrated water resources planning is emerging as a tool to develop water supplies and demand management strategies that are less vulnerable to the impacts of global warming. These tools include water conservation, reclamation, conjunctive use of surface and groundwater and desalination of brackish water and possibly seawater. Additionally, planning for future water needs should include explicit consideration of the potential range of global warming impacts through techniques such as scenario planning.

AbstractImportant aspects for understanding the effects of climate change on tropical cyclones (TCs) are the frequency of TCs and their tracking patterns. Coastal areas are increasingly threatened by rising sea levels and associated storm surges brought on by TCs. Rice production in Myanmar relies strongly on low-lying coastal areas. This study aims to provide insights into the effects of global warming on TCs and the implications for sustainable development in vulnerable coastal areas in Myanmar. Using TC records from the International Best Track Archive for Climate Stewardship dataset during the 30-year period from 1983 to 2012, a hot spot analysis based on Getis-Ord (Gi*) statistics was conducted to identify the spatiotemporal patterns of TC tracks along the coast of Myanmar. The results revealed notable changes in some areas along the central to southern coasts during the study period. These included a considerable increase in TC tracks (p value < 0.01) near the Ayeyarwady Delta coast, otherwise known as “the rice bowl” of the nation. This finding aligns with trends in published studies and reinforced the observed trends with spatial statistics. With the intensification of TCs due to global warming, such a significant increase in TC experiences near the major rice-producing coastal region raises concerns about future agricultural sustainability.
