The Impact of Capital Subsidy Incentive on Renewable Energy Deployment in Long-Term Power Generation Expansion Planning
Authors: ÖZCAN Mustafa , YILDIRIM Mehmet
Published: August 2019

Capital investment cost is the major obstacle to
the increasing share of electricity from renewable energy sources (RES-E). Therefore,
RES-E incentive mechanisms are incorporated into markets to compensate
cost-related barriers and to increase RES-E deployment rate. In this
study, the impact
of direct capital investment subsidy on RES-E in generation expansion planning (GEP)
has been analyzed and deployment rates of renewable power plants have been defined.
The effect of current
subsidy mechanisms on the installed power capacity of various sources has also
been analyzed and policy recommendations have been put forth in the light of
the characteristics of Turkey’s current subsidization mechanism and its outcomes.

Genetic algorithm was applied
to solve the GEP problem. The share of non-hydro renewable power plants for future
additions in overall installed
power was determined as 9.45% without the proposed incentive, while it was estimated
to rise to 13.65% when it was promoted by direct capital investment subsidy of
50%. The deployment rates of renewable power plants are expected to grow as the
imported coal share in total installed power is expected to decline after
applying the proposed subsidy.

Published: August 2019

The numbers of vehicles in the traffic and population density have been increased with rising affluence. Besides this situation, people are not enough information about the traffic. In 2013, the number of road accidents was 1.207.354 in Turkey according to the Turkish Statistical Institute. World Health Organization’s data in 2013 says that worldwide the total number of road traffic deaths is about 1.24 million per year. Along with these motivations, we developed a system for traffic education with both theoretical and practical exercises. The theoretical part of the system includes some tests which are about traffic, engine of vehicle and first aid information. The theoretical system has 10 test questions for each user. Another part of the system is a simulator with software and hardware. Firstly, in the system, a user answers the test and he/she should be successful at least 70 percent.  Then, the user can use the simulator. The simulator includes a steering wheel, a pedal system, a shift knob, a driver seat, a visual display and a virtual platform with software. With this system, inexperienced drivers will be able to acquire experience.

Type of enterovirus was detected in 2753 cases when examining 4122 patients with various clinical forms of enterovirus infection (EVI) during the 2017-2018 period. We identified viruses of 42 types belonging to Enterovirus A-B-С species. The ratio of EV-A: EV-B: EV-C species was 51.29 percent: 47.06 percent: 1.65 percent. In 413 environment samples 29 non-polio enteroviruses were identified, three of which, CA14, EVA76 and ECHO25, were not detected in the period in patients with EVI. The Coxsackie A6 virus, which caused a drastic increase in the morbidity of exanthema forms was the dominant agent in the etiological structure of EVI in 2017 in most areas; the leading etiological agents of enteroviral meningitis (ECM) were the ECHO30, ECHO9, ECHO18 viruses. There was a decrease in the morbidity of both all forms of EVI and computers due to a decrease in the activity of the circulation of epidemic variants of the Coxsackie A6 and ECHO30 viruses as a whole in Russia in 2018. The computer epidemic process in 2018 was supported by the become active or remained active viruses of ECHO6, Coxsacke B5, ECHO9, ECHO18 and other viruses of the Enterovirus B species. The remaining relatively high morbidity of exanthema forms of EVI in addition to the Koksaki A6 virus was supported by the activated viruses Koksaki A16, Koksaki A5 and other viruses of the Enterovirus A species. The results of phylogenetic analysis of genome sequences that dominated etiological agents of EVI indicate that in 2018 there was a multiple importation of enterovirus epidemic variants into the territory of the Russian Federation, which supported the EVI / computer epidemiological process in the Russian Federation as a whole and caused a complication of the epidemiological situation in a number of subjects. It is possible that these events contributed to the arrival of a large number of fans at the 2018 FIFA World Cup and visa-free entry into the territory of the Russian Federation for this category of tourists until the end of the year.

Sustainable Mining in Myanmar
Authors: Htun Kyi
Published: August 2019

Myanmar is endowed with abundant natural and mineral resources. However, environmentaldegradation and social impacts have increased in recent years due to foreign investment in the mining sector and the application of modern technology in mining and processing methods to increase productivity. The growing trend towards new mining methods, particularly the shift from underground to open-cut method to mine and process low-grade ores contribute to generation of large volumes of waste rock and tailings, presenting a major disposal challenge. Wastes containing sulfides will further degrade the environment. Absence of an efficient legal framework for Artisanal and Small Scale Mining (ASM) for gold and gemstones, and the application of mechanized mining both contribute to adverse environmental and social impacts of mining operations. Myanmar’s newly-promulgated environmental law (2012) provides no details about environmental and social impact assessment and participation of communities and their role in conservation of the environment. Efficient guidelines are needed and continuous monitoring and Life Cycle Assessment (LCA) are essential for the greening of Myanmar’s mining sector.
Sustainable Mining in Thailand: Paradigm Shift in Environmental Management
Authors: Niyomthai Saneh , Wattanawan Annuwat
Published: August 2019

Thailand’smining industry has always been considered as an industrial activity generating significant environmental burdens. This is because environmental management in the sectorwas given lower prioritycompared with economic benefits. The resulting adverse environmental effects in areas surrounding some mining areas required government interventions.Accordingly, the sustainable development of mineral resources requires a delicate balance of economic, environmental and societal considerations. To respond to this challenge, Thailand needs a paradigm shift in environmental management towards sustainablemining, in order to maximize benefits from exploitation of the mineral resources,whilst ensuring co-existence and mutual benefits of mining activities and their surrounding communities.This article seeks to provide some information about a fundamental change in theprinciples, approach and strategies of environmental management towards sustainable mining inThailand. The main mechanism includes changing in visions and strategies towards sustainable mining, applying various sustainability assessment tools in licensing and decision-making processes, decentralizing the environmental monitoring system to local authorities and communities, as well as enhancing the use of the sustainable development principle to all mining operators through various projects. An establishment of a rehabilitation fund, ahealth surveillance fund and a community infrastructure improvement fund are also required for development of any new mining project to guarantee rehabilitation works and risk management efforts during and after the mine’s life.

Published: August 2019

This research was conducted to estimate exposure and risk of exposure to BTEX (benzene, toluene, ethylbenzene and xylene)by a cross-sectional studying among pregnant women who lived in the vicinity of a petro-chemical industrial estatearea. Personal exposure was monitored by environmental and biological sampling.Other relevant data were gathered by a structured questionnaire for analysis. The relationship between BTEX exposure and potential risk factors was determined by multiple linear regression. Average BTEX exposure levels were 18.89, 29.40, 10.26, and 17.85μg m-3, respectively, which were significantlyhigher than the control group. Urinary metabolite levels of muconic acid(t,t-MA), hippuric acid (HA),mandelic acid (MA), andmethyl-hippuric acid (mHA)were significantly higher in pregnant residents living in the vicinity of the petro-chemical industrial estate area.The correlation between women’s individual exposure to BTEX and theirurinary metabolites showed significantlydifference between groups.Risks of benzene and ethylbenzene exposure for these pregnant subjects were approximately 4.37x10-7 and 1.92x10-8lower than the acceptable limits of United States Environmental Protection Agency(US.EPA.) guidelines(10-6). The hazard index (HI) of these pregnant subjects a lifetime rate was 0.555 which was below the reference level(HI < 1).Multiple linear regression analysis found that t,t-MA, HA, MA, and mHAin the urine of all models were significantly (p<0.05)and positively related with BTEX in ambient air.The study showed that there was a low cancer risk for pregnant women in the petro-chemical industrial estatezone. However, when compared with the control area, a statistically significant difference was found in the relationship between BTEX content in ambient air and metabolites in the urine of pregnantwomen. The implication is that the responsible government agencies should implement health surveillancecontinuously.
Production of Natural Dyed Palm Yarns and Fabrics
Authors: Chumsang Chanphen , Upan Pitak
Published: August 2019

Palm fibreis a waste product from the fruit crushing-extracting process in local communities. This study examined the characteristics of natural dyed palm yarns and fabrics producedfrom treated palm fibres. The results showed that fibre characteristics were improved by anaerobic fermentation, and following crushing and carding, were 3-5 times smaller, softer and more pliable.In the production of palm/cotton yarns of No. 7 (50/50), No.10(40/60), No.16(30/70)andNo.10(0/100),the 3-5 denier palm yarns and cotton yarns were spun in open-end spinning units. Regarding the physical properties, the blended yarns showed more unevenness and higher tensile strength and elongation at break than 100% cotton yarn. However, it was found that the coarser yarns were lower in strength than the finer yarns. Fibre sorting by denier leads to a decrease in unevenness caused by thin and thick patches and neps. When dyed with natural dyes, the palm yarns were found highly fast to light, but only moderately fast to washing.Dark dye spots distributed on the palm fibre yarns formed a natural pattern structure in the woven textiles. The tested woven textiles from the weft palm yarns are lighter in weight and higher in tensile force and tear strength than their cotton counterparts. The results suggest that palm fibre yarns should be promoted and introduced in Thai textile craft markets to provide diversity and added value to Thai textiles. Moreover, this study offers an opportunity to use palm waste to provide an alternative income source while preserving the environment in local communities. Such community-level industries may provide a sound basis for sufficiency community economies and green textile product development.

Published: August 2019

In this study sequential extraction was used to fractionate cadmium (Cd) and zinc (Zn) from soils into six operationally defined groups; water soluble, buffer-exchangeable, carbonate, FeMn oxide, organic, and residual. Soil samples from agricultural areas surrounding Pha Te village, Mae Sot District, Tak Province, Thailand, were classified into four categories; forest soil, upland soil, upper-paddy soil and lower-paddy soil. Total soil Cd and Zn concentrations ranged from 0.63 to 30.4 mg kg-1and 14.4 to 594 mg kg-1, respectively. Cd and Zn concentrations were higher in the upper-and lower-paddy soil (5.93 to 30.4 mg kg-1for Cd and 286 to 594 mg kg-1for Zn). These soils are considered as polluted. Cd in the polluted soil was dominantly associated with the buffer-exchangeable and carbonate-bound (40 to 70 % of total Cd), while in non-polluted soils; the residual fraction was dominant (50 to 80 % of the total Cd). The major proportion of Zn (37 to 46 % of total Zn) in the non-polluted soil and the upper-paddy soil occurred in the residual fraction. On the other hand, the major proportion of total Zn in the lower-paddy soil was associated with FeMn oxides (36% of total Zn). The results show that mobility and potential bioavailability of Cd and Zn (61 and 25 %) in polluted soil were higher than in non-polluted soils (15 and 19 %in Cd and Zn, respectively). Metal distribution in different chemical fractions in these soils depended on the respective total metal concentrations.
A Study of Residual Cyanides and Potential Stabilities in Tailings Storage Facility of Gold Mining Operation
Authors: Parinyachet Suwanit , Leepowpanth Quanchai
Published: August 2019

The study aimed to investigate residual cyanides and their potential stabilities in tailings from a gold processing plant deposited in the Tailings Storage Facility (TSF) of a gold mining site. For this purpose, several samples of tailings were taken from the recently abandoned TSF to a depth of 2.5 meters, representing 1 to 2 years old tailings. The samples were analyzed for pH, metals, residual cyanides, and Net Acid Generation Test (NAG test). The results showed that, in all samples, pH values were neutral to slightly alkaline. Fe concentrations were relatively high (22,800-35,000 mg kg-1) indicating that Fe can readily react with free cyanide (CN-) to form iron cyanide complexes (strong metal cyanide complexes). The residual cyanide concentration in tailings was found to be very low; free cyanide (CNFree), weak acid dissociable cyanide (CNWAD), strong acid dissociable cyanide (CNSAD) and total cyanide (CNT) were in the range of 0.16-0.64, 0.37-1.06, 1.96-3.89 and 2.33-4.95 mg kg-1, respectively. Cyanides in the tailings were predominantly strong metal cyanide complexes being more stable to dissociate. Total cyanide (CNT) concentration was quite low compared with Thailand’s environmental regulations for soil quality standards andwere environmentally insignificant. The NAG test for all samples revealed that NAG pH was in the range of 5.02-6.10 and NAG was in the range of 0.08-0.31 kg H2SO4t-1indicating all samples have low or non-acid forming potentials. The findings indicated a potential to form a high proportion of strong metal cyanide complexes in the tailings, which is difficult to dissociate and releasehigh toxic cyanide to the environment.

Authors: Akkajit Pensiri
Published: August 2019

This paper reviews contamination status, sources and remediation of Cd in agricultural land in Mae Sot District, Tak Province, Northwestern Thailand. The Cd contamination becamean environmental issue because mining of a Zn deposit area located uphill of the Mae Tao creekscaused movement of Cd and Zn along the creek to contaminate agricultural soils downstream. Blood Cd levels of residents in this contaminated area were found to exceed the national average of 0.5 μg g-1creatinine. The main route of Cd exposure in this area is the consumption of rice locally grown in this Cd contaminated area. Remediation of Cd-contaminated soils is therefore necessary to reduce public health risks. Remediation technologies considered include chemicalremediation and phytoremediation.
An Appropriate Guideline for Participatory GIS: A Result from the Experience of Joint Management of Protected Area Project in Thailand
Authors: Hemwan Phonpat
Published: August 2019

This study aims to examine the effectiveness of the Participatory Geographic Information System (PGIS) process as implemented through the Joint Management of Protected Areas (JoMPA) project. This article analyzes the process of local land use planning using PGIS through demarcation of special use zones. This was demonstrated to be a crucial process in the implemen-tation of conservation projects. Implementation of PGIS involves several operational steps, broughttogether in this study using the method of action research. It is based on collaborative partici-pation by stakeholders in the local area, leading all stakeholders to effective co-management of resources. The means of PGIS is also discussed here as a set of key tools, comprising geo-information acquisition and analysis tools. They are used mainly as participatory and interactive tools for communication and decision-making in collaborative planning or public meetings. The results of this implementation indicated that villagers could clearly understand the boundaries of land use areas, and the community regulations to facilitate practical co-management of land use by all local stakeholders. In addition, this study evaluates intensities of participation in 3 dimensions: facilitation, mediation and empowerment. This integrated approach including participatory local land use planning with PGIS is useful to identify problems in protected areas and also to develop strategies and solutions in partnership with local communities and external stake-holders, that together lead to a co-management approach for protected areas.

While the institutional infrastructure to coordinate climate change policy in Thailand alreadyexists, previous studies have identified an important gap in this infrastructure. An institutional arrangement/coordinating mechanism is needed to oversee coordination of resource allocation and utilization among government agenciesin order to achieve the national goal of a low carbon and resilient society. This paper reviews current policies and institutions related to climate changeand recommends a new Sub-committee on Climate Finance be established under the National Climate Change Committee (NCCC). Alternatively, the existing sub-committee could be renamedas a Sub-committee on Climate Finance and Planning. Having a specific coordinating mecha-nism on climate finance would facilitate the government’s oversight of allocation of financial resources, tracking and monitoring of resource use, and also serve as a check point for resource allocation to prevent redundancy in terms of activities and allocated climate change funds. Thisinstitutional proposal may also be relevant and applicable to other developing countries facing similar challenges.

Climate change is a critical issue for all of humanity. It is predicted that Thailand is likely to have an increasing frequency and intensity of rainfall and storms which, will result in a more severe flash flood problem. Slum residents in Chiang Mai are one of the groups of people who are vulnerable to flooding impacts of climate change. The objective of this study is to analyze the flood-resilient housing style of low-income people. Data from 3 slums (146 households) which encounter different kinds of floods every year, i.e. drainage floods (Ban Sanku: 21 households), river floods (Kampang Ngam: 64 households) and flash floods (Samunkee Pattana: 61 house- holds), were collected. The study found that flood frequency, duration, depth and flow velocity caused damage to the houses, but only flood frequency, duration, and flow velocity were factors affecting the housing structure. If considering only damage to slums which frequently face shallow water depth, slow flow velocity and short duration, all 8 low-income housing styles (A-H) can be built. The high platform house with open space under the house is appropriate for slums located in flooding area where high-level, slow flow velocit y floods occur frequently but for a short duration. It may be a permanent, semi-permanent or temporary structure (D-F). For the other slums facing high flood levels with high flow velocities for a short duration, all permanent housing styles are appropriate. If the objective is not only damage prevention but also living during a flood, per- manent high platform houses with open spaces under the houses are recommended for all slums.

Knowledge of the concentration of polycyclic aromatic hydrocarbon (PAHs) in urban soils remains insufficient in developing countries like Nigeria despite their toxic effects and suspected human carcinogens, mutagens and endocrine disruption. This study aimed to determine the concentration of PAHs in soil of three dumpsites in Abeokuta metropolis, Ogun State, Nigeria. Concentrations of individual PAHs were determined using Gas Chromatography Flame Ioni-zation Detector (GC-FID). The total PAHs concentrations at 0-15 cm depth were 29.0 mg kg-1, 41.6 mg kg-1 and 11.9 mg kg-1 for Igbore, Saje and Alogi dumpsites respectively while the corres-ponding total PAHs concentrations at 15-30 cm depth were 9.3 mg kg-1, 28.3 mg kg-1 and 11.0 mgkg-1respectively. These concentrations were slightly lower than the Dutch guideline limits of 40 mg kg-1 except for that of Saje at 0-15 cm depth. The amounts of fluoranthene at Igbore dumpsite in the two depths were 23.64 mg kg-1 and 8.02 mg kg-1, with a total sum of 10 PAHs compounds of 19.12 mg kg-1. The results showed that the highest concentration of a single PAHs compound was at Saje dump-site with fluoranthene value of 33.75 mg kg-1 and 22.74 mg kg-1 at the depths of 0-15 and 15-30 cm respectively. Isomer ratio for fluoranthene/pyrene was 2.69 at Alogi dumpsite, which suggested that the PAHs were from pyrogenic sources. Carcinogenic PAHs constituted about 1.29-15.69 % of the total PAHs detected in the dumpsite raising concerns of human exposure through the food chain.

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 approaches. Questionnaires were distributed to 70 randomly-selected agri-cultural households in Village 4 of the Nongbuasala sub-district, Nakhon Ratchasima, Thailand. The survey results indicated that the majority of respondents view climate change in terms of extreme high temperatures and flooding. Regression analysis also revealed positive correlations between perceptions of climate change and six psychological variables of awareness in general andmitigation, belief in the reality of climate change and human causes, feelings of worry, and self-efficacy (0.201 ≤ r≤ .592; p ≤ 0.05). Conversely, in terms of perceived barriers, three compo-nents of cognitive dissonance (r= -0.831), belief in limitation of lifestyle changes (r= -0.305) and fear (r= -0.283) were found to be negatively correlated with climate change perceptions by Thai farmers. Recommendations to deal with those perceived barriers are also discussed.

Seed germination trials have relevance in measuring soil toxicity. The current study was there-fore conducted to investigate the effect of municipal solid waste incineration fly ash (MSWIFA) and sewage sludge (SS) from the Phuket municipal waste incinerator and wastewater treatment plant as fertilizer substitutes on seed germination and growth parameters of sweet corn (Zea maysL.). A field experiment was conducted at the National Corn and Sorghum Research Station, Na-khon Ratchasima Province, using a randomized complete block design (RCBD). The treatmentsconditions were: 1) non-amended soil, 2) 378.125 kg MSWIFA ha-1, 3) 543.75 kg SSha-1,4) 756.25 kg MSWIFA ha-1, 5) 1087.5 kg SS ha-1, and 6) 378.125 kg MSWIFA ha-1 + 543.75 kg SS ha-1. The results indicated that application rates of MSWIFA and SS have profound effects on plant establishment and growth characteristics. The highest germination index (22.26), vigorindex (146.4), leaf number (5.65), and fresh and dry weight (5.78 and 2.35g plant-1), respect-tively) were recorded from seeds treated with SS (1087.5 kg ha-1), while the highest seed ger-mination was found in 378.125 kg MSWIFA ha-1 + 543.75 kg SS ha-1. The result suggested the alternative use of MSWIFA and SS without addition of fertilizer on agricultural soils.

This investigation aims to study the value of synthesized zeolite in reducing greenhouse gasses (GHGs) emitted by rice stubble. The experiment was divided into 2 parts. Part I com-prised a study of the efficiency of GHGs reduction by synthesized zeolite and part II involved application of synthesized zeolite to reduce the cumulative GHGs emissions over 110 days from paddy rice cultivation in Khlong 4, Pathum Thani Province. The experiments comprised 2 treatments: untreated control (I), and rice stubble with addition of synthesized zeolite (II). The study measured changes in the emissions of CH4 and CO2, conducted 3 d per week for 1.30 h during the cultivation period. The result s showed that rice stubble synthesized zeolite could reduce GHGs CH4 and CO2under irrigated conditions. In the experiment, synthesized zeolite had an efficiency of 8.91% and 24.5% in reducing CH4 and CO2, respectively. Footprint analysis showed that both gases were continuously emitted throughout cultivation. In Cumulative emissions from the control treatment were 42.57 g CH4 m-2 cropand 86.40g CO2 m-2 crop. Zeolite addition reduced emission levels to 30.71 g CH4 m-2 crop and 57.77 g CO2 m-2 crop. The reduction efficiencies CH4 and CO2 were 27.87% and 33.14%, respectively. It can be concluded that the rice stubble synthesized zeolite was capable of reducing GHGs significantly and that the efficiency was rate-dependent. It was clear that the GHGs emission reduction rate of synthesized zeolite was 0.148 g CH4 m-2 g zeolite and 0.358 g CO2 m-2 g zeolite.

Published: August 2019

In this research, ground penetrating radar (GPR) was used to determine the volumetric soil water content (VSWC) of a loamy soil. The GPR was set up in the ground wave fixed offset me-thod using both 400 and 900 MHz frequency antennae. By estimating the relative dielectric per-mittivity of the soils, these values were converted to the VSWC by Topp’s equation. The gra-vimetrically calculated VSWC values from the soil samples at different depths were used as thereferences. In addition, the ability of the GPR method to detect variation in the VSWC over time was evaluated in three periods spanning the dry and rainy seasons. The VSWC estimated from the400 MHz analysis had a high correlation with the gravimetric method under dry conditions at a soil depth of 10-30 cm and under wet conditions, the result was reasonable at 10-20 cm. In contrast, the 900 MHz derived VSWC estimateswere not related to those from the gravimetric analysis, although the results were reasonable in dry conditions. The VSWC values obtained fromthe 400 MHz antenna give a reasonable estimation of VSWC of this site. Thus, the GPR method is appropriate for estimating the VSWC due to the ease of data acquisition and processing.
