Species-Specific Responses Of Water Use By Urban Trees To Artificial Soil Drought: Results From A Small-Scale Study, Pantana Tor-Ngern, Somsak Panha

Applied Environmental Research

Studying tree water relations in response to soil drought improves our understanding of hydrological processes that are central to most ecosystem modelling. Urban greening is an approach to ameliorate rising carbon dioxide emissions whose effects are intensified in cities. Thus, an investigation of water relations with respect to drought of urban trees is of interest for effective watermanagement in urbangreening. This study examined responses of sap flux density, water use and stomatal conductance of potted saplings of three common street trees in Bangkok: Pterocarpus indicus (Pi), Swietenia macrophylla (Sm) and Lagerstroemia speciosa (Ls); under one-week non-irrigated treatment. Results showed that …

Influence Of Psychological Factors On Climate Change Perceptions Held By Local Farmers In The Northeast Of Thailand, Suthirat Kittipongvises, Takashi Mino Sep 2015

Influence Of Psychological Factors On Climate Change Perceptions Held By Local Farmers In The Northeast Of Thailand, Suthirat Kittipongvises, Takashi Mino

Applied Environmental Research

Global climate change is considered one of the most critical socio-ecological challenges of the 21st century. In recent years extreme weather events have increased significantly in Thailand asin other parts of the world. In most cases, climatic variability has always been associated with its implications for agriculture. To date, however, there has been inconclusive understanding of farmers' capacity to detect climate change and its potential impact. This study therefore explores how Thai farmers perceive global climate change and, further, to examine the influence of psy-chological factors on these perceptions. The study used mixed research methods, with both quali-tative and quantitative …

Air Quality Monitoring Around The Developed Area Of Chulalongkorn University In Kaeng Khoi District, Saraburi Province, Surawit Intarasunti, Pantawat Sampanpanish

Applied Environmental Research

The construction project for the developed area in Kaeng Khoi District, Saraburi Province, Thailand, drafted by Chulalongkorn University has raised various concerns over environmental impacts, particularly relating to public health and air quality. In order to investigate impacts of this project, air quality sampling was conducted in Tan Diew Sub-district, Huai Haeng Sub-district, Cham Pak Paew Sub-district and some surrounding sites of Chulalongkorn developed area by gravimetric method using a high volume air sampling machine. Two types of particulate matter including total suspended particulate matter (TSP) and particulate matter < 10 µm (PM10) were continuously monitored during all 3 seasons for a study period of 3 years in order to compare the effect of seasonal variation on the amount of particulate matter generated in each study area, to study the correlation between TSP and PM10, and finally to identify other causal factors related to particulate levels. Results from this study indicated that TSP and PM10 both reached the highest in winter followed by summer and appeared to be at the lowest level during the rainy season. In addition, causal factors such as wind direction and human activities also influenced particulate levels in each study area.

Teak Log Coffins In Northwest Thailand: Dated By Dendrochronology And 14cwiggle Matching, Nathsuda Pumijumnong, Sineenart Wannasri

Applied Environmental Research

Log coffins have been discovered in caves and rockshelters in the Pang Ma Pha district, Mae Hong Son province, Northwestern Thailand. Most are made of teak wood. Many researchers have used the 14C method to determine their age. However, 14C cannot provide as precise a ca-lendar age as dendrochronology. In this paper, we therefore applied dendrochronology analysis to a number of teak log coffins at the Ban Rai Rockshelter to establish a floating chronology and to cross-date the coffins relative to each other. Then, wiggle matching was used for one log cof-fin to derive an approximate but absolute calendar age. …

Best Management Practices For Sustainability In A Small-Scale Community Renewable Energy: Sathya Sai School, Thailand, Panichat Kitisittichai, Ariya Aruninta

Applied Environmental Research

Organizations working towards standardization have defined universal standards for Best Management Practices (BMPs) for renewable energy (RE) projects. However, these universal standards are better suitedto large-scale than small-scale projects such as community renewable energy (CRE) projects. Methods used by CRE projects to achieve BMP status remain to be determined. This paper aims to present various aspects of BMPs for small-scale CRE projects by emphasizing practices that are unrestricted, simple, andadaptable to the surrounding environment, and that will eventually lead to sustainability in the commu-nity. The case study involves RE projects at the 'Sathya Sai School Thailand,' an education-based com-munity which …
