Abstract 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 m 3 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

One of the main challenges in developing countries like Nepal is inefficient management of municipal solid waste. Provision of fundamental services for municipal solid waste management is a major concern in urban areas of Nepal, especially in the capital Kathmandu Metropolitan City (KMC). The formal waste management system of KMC is limited to collection and disposal in landfill site or open dumping. Intermediate steps are not opted formally for resource recovery or treatment of the waste. In view of the challenges encountered, the Asian Development Bank has recommended adopting integrated solid waste management. The study aims at developing and accessing scenarios for integrated solid waste management that is pertinent to the case of KMC. The specific objectives include defining different integrated solid waste management systems and determining their energy recovery and material recovery efficiencies. The first waste management system is material recovery-based system. The second waste management system is energy and material recovery-based system. Additionally, a SWOT (strengths, weaknesses, opportunities, and threats) analysis of the two proposed waste management systems was carried out to recommend the more appropriate system, in the context of KMC. Results of the study depicted that material recovery efficiency of the second system is lower than the first system, however, the electrical energy efficiency is especially prominent for second system. Based on the results of material and energy recovery efficiency calculations and the outcomes of the SWOT analysis, adoption of the material and energy recovery based waste management system is found to be instrumental for efficient management of municipal solid waste in the context of KMC. In view of the negative impacts imposed by the current improper municipal solid waste management in KMC, implementation of the material and energy recovery based integrated solid waste management system will be beneficial in not only effectively managing the municipal solid waste but also provide resources by recovering material and energy from the waste generated. However, if following the waste hierarchy, the material recovery based system would be preferable. In the short term, the energy and material recovery-based system may be considered. But risks of technological lock-in effects in the long term can be detrimental in realizing and taking advantage of the material recovery potentials.

Environmental Sustainability of Food Consumption in Asia

This study assesses the environmental sustainability of food consumption in Thailand, India, China, Japan, and Saudi Arabia by using a life cycle assessment. These five Asian countries were selected according to the differences in surface area, population density, GDP, and food consumption patterns. The data were obtained from Food and Agriculture Organization food balance sheets, Ecoinvent 3.4 and Agri-footprint 4.0 databases, and scientific publications. The environmental impact categories chosen were global warming, terrestrial acidification, eutrophication, eco-toxicity, human toxicity, and fossil resource scarcity. The impact assessment was carried out by using the ReCiPe2006 v1.1 method. Based on the analysis, the highest environmental impacts for all categories (except eutrophication) were from the food consumption in China, followed by the consumption in Japan, Saudi Arabia, Thailand, and India. The major contributors to these impacts were meat, cereals, animal products, and alcoholic beverages. Meat was the highest contributor in all countries except India, because of low meat consumption in India. A calorie intake analysis was also conducted, which showed reductions in environmental impacts by shifting towards calorie-adequate and non-environmentally intensive diets in Thailand, China, Japan, and Saudi Arabia. Therefore, a reduction in the consumption of meat, cereals, animal products, and alcoholic beverages could therefore enhance the environmental sustainability of food consumption.
