This research aimed to explore the Land Use/Land Cover change in the Eastern of Thailand
related with the characteristic of urban heat island by analyzing and estimating the visible and
near-infrared and thermal of Urban Heat Island (UHI) phenomenon that cover agricultural,industrial, and urban areas in the eastern region by using climate models in GeographicInformation Systems (GIS) and RS (Remote Sensing) data, which it integrates land surfacetemperature (LST), with estimated by single-channel algorithm for Landsat satellite data and
ground-based weather stations in 2006, 2011 and 2017 years. The eastern region of Thailand isthe intensive industrial development region of the country, as a result, the region has developedand expanded into a city more than other regions. Land use is decreased in agriculture and
forest and increasing of city/building all province in the region. Many of vacant land and
agricultural land were replaced by roads, infrastructures, and buildings. There are many ofurban communities and industries located spread throughout the region especially Chon Buri,Rayong, and Chachengsao provinces. Buildings and its surfaces and transport systems whichconstructed by brick, concrete and asphalt act as enormous heat storage also, it accumulateswith the human and industrial activities of urban areas, have been caused urban zone to havehigher temperatures than the surrounding countryside area. From the study, many cities in theregion has significant increasingly temperature.
The research found LST and UHI of Eastern Region that urban and industrial areas that have ahigher temperature compared to the surrounding agricultural areas, these different temperaturescause the formation of UHI. This study recognizes that the level of LST and UHI provinceincreased to be the strongest in 5 provinces: Chon Buri, Prachin Buri, Sa Kaeo and
Chachoengsao. UHI effect is a significant factor linking to anthropogenic sources, to protect theenvironment and to mitigate the UHI effect there involves different environmental strategies,
one of the important strategy is a greening city, increased of green cover surface area in cities,
within green infrastructure methods and techniques, urban agriculture is an alternativemitigation which currently being considered. Urban Agriculture is considered as an opportunityto mitigate the environmental impacts, because, urban agriculture can play a strong role in enhancing food security by providing agricultural products to the residents of the city, greening
the city and improving the urban climate.
