The aim of this research is to project climate change-induced rainfall for three future periods using three dynamically downscaling regional climate models (RCM1–RCM3) based on three respective global climate models: ICHEC-ECEARTH, MPI-M-MPI-ESM-MR and NOAA-GFDL-GFDL-ESM2M. The projections are carried out under two representative concentration path...

The rate of respiratory system diseases in humans is continually increasing worldwide. This increase correlates with a decline in air quality. Increased air pollution worldwide is a major contributing factor to air pollution affecting the human respiratory system, resulting from both human and natural activities. However, in the modern era, air pol...

Air pollution, a significant global challenge, hinders economic growth, exacerbates poverty and inequality, poses risks to human health, and contributes to climate change. This issue is frequently observed in densely populated urban areas, primarily because of lower atmospheric diffusion capability and the accumulation of air pollutants. Industrial...

Weather and climate are related but separate meteorological concepts. Weather involves daily atmospheric conditions, including temperature, precipitation, humidity, wind, and pressure. Solar energy distributions, atmospheric circulation patterns, and land–ocean interactions determine weather patterns. Weather forecasting can benefit industries such...

Adverse health outcomes from exposure to air pollution have been documented for decades. Not only outdoor air pollution but also indoor air pollution also has harmful effects. Indoor air pollution significantly affects occupants’ health as people spend most of their time indoors performing activities of daily living, working, and sleeping. Numerous...

Bioaerosols are crucial indoor air pollutants often neglected by occupants unless serious contamination exists. They originate from living organisms, including microorganisms (i.e., fungi, bacteria, and viruses), arthropods (i.e., dust mites, cockroaches), house pets, and humans. Fungi and bacteria are common bioaerosols observed in the indoor envi...

This research proposes a collection of urban heat island (UHI) risk indicators under four UHI risk components: hazard, exposure, sensitivity, and adaptive capacity. There are 46 UHI risk indicators linked to three pillars of sustainability: social equity, economic viability, and environmental protection. In this study, the UHI risk indicators were...

This research proposes a set of 12 self-assessed air pollution adaptive capacity (APAC) indicators to determine and mitigate individual-level air pollution-related health risks. In the study, the APAC indicators were first statistically validated based on data from panels of experts using structural equation modeling. The validated indicators were...

This research proposes an updated version of homestay indicators for 10 existing component-level homestay requirements. The updated indicators were aimed to replace the decade-old original indicators for Thai homestay businesses. Besides, the 31 original homestay indictors were not statistically validated. In this study, structural equation modelin...

Climate change-induced heavy rainfall could bring about flash floods in urban areas. In Thailand, flooding is frequent and widespread, especially in the country’s northern, northeastern, and central regions. Extended periods of heavy rainfall cause flooding as the rainwater exceeds the water absorption capacity of the ground. On several occasions,...

Urban floods have a significant impact on the economy, livelihoods, and daily activities. Despite extensive research on flood adaptation, there is a lack of consensus on ways to assess flood adaptive capacity. This research thus proposes an assessment framework of flood adaptive capacity of urban residents in flood-prone areas. The indicators are b...

This research investigates the impact of land use transformation and anti-flood structural infrastructure on flood situations in four flood-prone districts of Thailand's Ayutthaya: Phra Nakhon Si Ayudhya (PNSA), Bang Ban, Phak Hai, and Sena. PNSA is a UNESCO world heritage city and the cultural and economic hub of Ayutthaya. The finding showed that...

Flooding in Thailand’s capital, Bangkok, impedes the development of the city and brings challenges to the well-being of its citizens. The city is situated in a flood-prone area. This study investigated perceptions of the causes among the residents of perennial floods in Bangkok, examining daily precipitation changes over the last 30 years on eight...

This research investigates the impacts of the repetitive flooding on the inhabitants of the four flood-prone districts in Thailand's central province of Ayutthaya: Pranakorn Si Ayutthaya, Sena, Bang Ban, and Pak Hai. In addition, the residents' satisfaction levels with the flood relief efforts and operations of the local authorities were examined a...

This research has investigated the changes in land use of an area adjacent to a university over the past 30 years to predict the future use of land in the next 5 years (through to the year 2019). The study area is 2,000,000m² (1000x2000m) in size and is located on the east side of Rajamangala University of Technology Thanyaburi (RMUTT) in Thailand’...
