“…where current value of cost, CVC 2011 , is the Thai people's budget to pay for avoiding 1 DALY of 512,000 THB in 2011 and in 1 PDF in m 2 during 1 year of 0.88 THB in 2011 (derived from 8800 THB/BAHY, and 1 BAHY = − 10,000 PDF m 2 year) estimated by Kaenchan and Gheewala (2017), r is the average inflation rate of Thailand between 2011 and 2019 relying on the obtained inflation rate (GDP deflator) from The World Bank Group (2021), that is 1.83%, and t is the reference year of currency used in the valuation (i.e., 2019). Eventually, in ecosystem quality damage cost assessment, applying a conversion factor of 1 year is 365.25 day 2011) (NASA Official.…”

Purpose Existing emission and toxicity characterization models in life cycle assessment are currently not suitable for assessing pesticide-related impacts of crop cultivation in tropical regions. This study aims to parameterize the scientific consensus model USEtox for Thai environments to derive toxicity characterization factors of pesticide emissions from agricultural systems in Thailand. Potential human toxicity and ecotoxicity impacts and related damage costs of pesticides used on nine crops cultivated in Thailand are quantified. Methods Considering country-specific conditions, USEtox was adapted by applying the landscape and consumption parameters specific to Thailand. Related Thai-specific characterization factors of identified pesticides used in Thai agriculture were quantified. Four emission inventory models were applied to determine pesticide emission fractions in different environmental compartments. The consistent combination of pesticide emission mass and associated characterization factors yielded potential toxicity impact scores. Pesticide impact-related damage costs (external costs) on human health and ecosystem quality were quantified using valuation factors for Thailand. The crops with the highest total damage costs were selected and compared with the annual net incomes of the respective crop production systems. Results and discussion Pesticide toxicity impacts assessed by using Thai-specific factors were different from the use of global average factors ranging from 1 to 169% (human toxicity) and from 0.1 to 3587% (ecotoxicity). Our results indicated the variability in impact scores influenced by emission modeling choices. Following PestLCI consensus emission estimation model, mango cultivation showed the highest human toxicity impacts of 0.07 DALY/ha, resulting in high human health damage costs mainly caused by Propineb (93%). Rice cultivation with a dry direct-seeded system exhibited the highest ecotoxicity impacts (3934 PDF m3 day/ha) and associated damage costs mainly caused by Oxadiazon (92%). Pesticides used in cultivation of nine crops resulted in total damage costs of 7188 and 3.01 million THB/crop-year for human health and ecotoxicity, respectively. Mango and rice production accounted for 70% and 17% of the total damage costs, which were 36% and 20% of the respective crops’ annual net income. Conclusions Our study illustrates the ranking of pesticides applied throughout the crop calendar causing toxicological impact and related damage costs on human health and ecosystem quality. This helps identify crops and the main contributors to pesticide-related toxicity impacts in Thailand. Our study highlights the need for proper emission quantification and for the use of characterization factors locally parameterized to increase accuracy. Our results will be useful for future improvement toward more sustainable pesticide use. Graphical abstract

“…Furthermore, pricing metrics, based on non-market and global value transfer methods, may provide inaccurate country-specific value measurements. Hence, a recent Thailand-specific study, based on an alternative budget constraint method, found that external costs amount to 19% of the Thai retail price of palm biodiesel (Kaenchan and Gheewala, 2017). In contrast, our market-based approach is specifically designed to assess pecuniary economic and welfare impacts, and, at the same time, provide holistic and consistent modelling of a range of (non-monetized) multi-dimensional outcomes, including non-pecuniary nutritional, clinical health and environmental outcomes, and thereby allow policymakers to make informed policy choices based on established trade-offs (and based on their own implicit weighting of pecuniary and non-pecuniary outcomes).…”

Highlights Fully integrated Macroeconomic-Environmental-Demographic-health model. Palm oil sales tax creates dietary and health improvements. Palm oil sales tax causes temporary economic losses and adverse environment impacts. Policymakers should consider trade-offs when using fiscal food policy instruments. Fiscal food policy research should include both food and non-food policy indicators.

“…The damage to human health is represented in units of Disability Adjusted Life Year (DALY), the damage to ecosystems is presented in units of Potentially Disappeared Fraction of species (PDF.m 2 .yr), and the damage to resources is quantified in monetary units. The damages could be converted into monetary units (THB) on the basis of the monetary conversion factors provided by Kaenchan and Gheewala [33]. However, before being utilized, the monetary conversion factors were adjusted for the time value of money following Haputta et al [34] as explained in Equation (18) where MCF 2017 indicates the value of monetary conversion factor in 2017; MCF y denotes the value of monetary conversion factor in the year that it was initially calculated (year y); and r is an average inflation rate of Thailand over 2008-2017, i.e., approximately 0.02 [35].…”

: Following Thailand’s Alternative Energy Development Plan, lands for sugarcane and oil palm are being expanded to support biofuel production, thus decreasing the availability of land for other crops. Not only does this lead to the change in Gross Domestic Product (GDP) but also environmental consequences. This study assessed the effects of land expansion caused by biofuel promotion on Green GDP, which is the conventional GDP after adjusting for environmental damage. A static computable general equilibrium (CGE) model combined with life cycle impact assessment was used to estimate the effects of land expansion on economic transactions and conventional GDP. Results showed that compared with the business-as-usual scenario, expanding land for biofuel crops increased the Green GDP. However, rice cultivation and milling were adversely affected by the substitution of biofuel crops. Furthermore, expanding biofuel crops slightly reduced the production capacity of some industrial sectors. The Green GDP for biofuel crop expansion policies was greatest when abandoned rice fields were utilized for agriculture and lowest when forests were transformed. Using CGE to investigate the effects of policy on Green GDP yielded results that were comprehensive for decision making. The method presented in this study can be utilized for future Green GDP research focusing on other biofuel productions.
