Purpose: This study aims to evaluate the current situation of education for sustainable development, climate change education and environmental education in a nationwide context. Methodologically, this study calls for more research to go beyond case studies and take a similar approach to examine university curricula and facilitate cross-country comparisons. Design/methodology/approach: This paper examines the status of climate and sustainability curricula in Taiwan's higher education system. Using the course catalog for the 2020–2021 academic year, the authors constructed a unique data set that includes 1,827 courses at 29 major universities in Taiwan. In each institution, the authors search for course titles that include "climate," "sustainable/sustainability" and "environment/environmental" as keywords and code the courses according to their disciplines. Findings: The finding highlights the variations across institutional types and subject matters. Public universities have an average of 4.94 related courses per 1,000 students, whereas private universities have only 3.13. In general, the relevant courses are more concentrated in the STEM and bioscience fields. The curricula, however, are seriously constrained by the disciplinary structure and foster few transdisciplinary perspectives. Originality/value: The authors seek to go beyond case studies and offer one of the most comprehensive curricula samples at the national level. Taiwan adds an important data point, as the current literature focuses heavily on the USA and Europe. [ABSTRACT FROM AUTHOR]

The implementation of Community-engaged research (CenR) has faced many challenges in the context of the COVID-19 pandemic, especially when researchers are based in another part of the country or the world. This paper presents a researcher's initiative for implementing CenR in partnership with local universities, particularly engaging local students to become part of the communities and bridge the gap between researchers and communities. The project aims to engage local communities working in tourism services in assessing their adaptive capacity (AC) to climate change in the Vietnamese Mekong Delta (VMD). Notably, this study was conducted with the researchers being located in Taiwan while the research area was situated in the VMD. Methods used include field trips, in-depth interviews (IDIs), focus group discussions (FGDs), local workshops, and people participation geographic information system (PPGIS). Two groups of students at Kien Giang University (KGU) and Dong Thap University (DTU) (Vietnam) were involved. The article provides the process of engaging with local students, from searching and selecting them, to obtaining consents, engaging and building trust, training and guiding them in field trips, engaging with local communities, collecting and analyzing data, and developing future projects in those communities. The study offers a novel approach that can be extrapolated in the context of global system crises such as climate change, disasters, or emergency situations in remote areas that often experience limited connectivity with the outside world. By encouraging the creativity of students and researchers, this study promotes the continuity of research efforts even in times of uncertainty and crisis. [ABSTRACT FROM AUTHOR]

The Taiwan government has been following the green energy policy for decades to cope with drastic climate change due to global warming and tremendous urbanization. Forming a database to assist Taiwanese policy makers in using the concept of energy efficiency and environmental comfort in urban planning and architectural design is required. This paper depicts how the field and CFD studies for an industrial region located in rural and monsoon wind prevailed district of the mid-western coast Taiwan were conducted, and how the data are used to construct building layout principles for regions having similar climate conditions. For the purpose of analyzing field data and forming database, measured atmospheric and microclimate parameters, such as the physiological equivalent temperature (PET), were first converted into empirical relations. Then, these empirical equations were used as the input and validating values for the CFD simulation model based on the FLUNENT software. Five field-observed wind profiles were used as the inlet conditions, and the computed results of the five-street canyon aspect ratio, and of four-building arrangements, are analyzed to construct the building layout principles. The study results show that the principles for a monsoon wind prevailed region should better be the following: (1) the street canyon aspect ratio is 0.1 and not over 0.3; (2) the building layout is a single open arrangement, avoiding a staggered setting.

Urban heat island (UHI) and global warming effects will raise the ambient temperature of cities and increase building energy consumption. This paper discusses the residential cooling energy variations imposed by urban warming in the present and future. Data from a dynamically downscaled hourly meteorological model with a grid resolution of 5 km and for time slices 1979–2003, 2015–2039, and 2075–2099 were used for dynamic building energy simulation against a typical residential apartment in the central Taiwan region. The meteorological grids were classified as 4 city grids, 25 town grids, and 31 countryside grids based on their urban morphology attributes. The values from 20 countryside grids with lower average ambient temperatures during cooling seasons were selected as reference. The spatial and temporal distributions of the impact of indoor overheating risk and annual cooling energy consumption by UHI and global warming effects were quantified against the reference value. Furthermore, because the energy penalty can be used to rapidly estimate the urban warming impact on total cooling energy consumption of a given city, the linear correlation of the energy penalty and the magnitude of the UHI effect was also established and discussed.

Under the UNFCCC, governments have adopted a universal climate change agreement, the Paris Agreement, near the end of 2015 covering nearly all countries from 2020, and will endeavor to find ways to scale up efforts before 2020 beyond the existing pledges to curb emissions, so that the world can stay below the agreed maximum 2 °C temperature rise. In view of long-term planning strategy, many countries have adopted the year 2050 goals, and science strongly indicates that any further delay in appropriate global mitigation efforts will increase the pressure towards our low-carbon future. This paper discussed the multiple challenges and searches for the optimal pathways in promoting the transformation of future renewable energy systems in Taiwan, especially its practical implementation aspects. While developing Taiwan׳s climate legislation and strategies, in addition to having the participation of both the public and private sectors in order to act aggressively to overcome policy obstacles, active dialogues with the stakeholders and the general public were also promoted which helped to improve public awareness and build up consensus. The end result is the promulgation of the 2015 Greenhouse Gas Reduction and Management Act which stipulates Taiwan׳s short and long term climate goals and development of corresponding measures, and the formulation of Taiwan׳s Nationally Determined Contribution which serves to foster a facilitative environment and create tremendous business opportunities for the booming green industry in Taiwan.

This paper presents the first high-resolution Holocene stalagmite record of Taiwan from Jianfei Cave (22°50.873 N; 120°21.255 E) in Dagangshan Mountain, South Taiwan. The 13.6-cm long stalagmite (DGS-1) has been dated by AMS 14 C dating, spanning from AD 700 to AD 1933. The δ 18 O, δ 13 C and XRF scanned elemental profiles reveal interannual variations in climate and environmental conditions, with light δ 18 O and δ 13 C excursions reflecting wet climate and better vegetation coverage under stronger East Asia Summer Monsoon (EASM). Dark layers in DGS-1 containing high Fe, Mn and Sr contents were formed during dry episodes. Five periods with different climate regimes and vegetation conditions can be identified in the DGS-1 record: Period I (AD 700–1200) and Period V (AD 1810–1933) had warm and wet climates with good vegetation coverage. A drying trend probably corresponding to the switch from El Niño-like to La Niña-like oceanic condition occurred during Period II (AD 1200–1400). Cold but relatively wet climates with good vegetation coverage were prevailed during Period III (AD 1400–1610), whereas cold and dry climates with poor vegetation coverage were dominated during Period IV (AD 1610–1810). Based on the rainfall record of Tainan since AD 1897 and the stalagmite record, we found that stronger total solar irradiation (TSI) resulting in strong EASM produces heavy rainfall in South Taiwan on interannual-to-decadal scales; and vice versa. The 117-yr instrumental rainfall record of Tainan showed that rainfall in Tainan decreased during April-to-June and strongly increased during July-to-September in many La Niña years (positive SOI and negative Niño 3.4). This may be because weaker Meiyu rainfall but stronger tropical Equatorial Pacific cyclones (or typhoon) under La Niña condition. Thus, it is better to use seasonal rainfall for detecting relationship between Tainan rainfall and ENSO. On decadal-to-centennial scales, strong El Niño-like state and warm Pacific Decadal Oscillation (PDO) phase are in favor of wet conditions in South Taiwan. [ABSTRACT FROM AUTHOR]

Taiwan, a country in the subtropics, heavily depends on imported energy with over 99% of its energy imported. In this regard, scrap tires for use as an energy source has thus became attractive in the past two decades. The objective of this article is to present a comprehensive analysis of tire-to-energy in Taiwan. This article gives a concise summary of the current status of scrap tire production and its recycling in recent years. It was found that a major scrap tire market in Taiwan (about three-quarters) is used as fuel in the cement, power, and paper and pulp utilities. Under the authorization of the Energy Management Law, the central competent authority has promulgated the regulations to encourage energy-intensive industries to participate in the cogeneration system through excess electricity purchase and financial incentives. Using the method recommended by the Intergovernmental Panel on Climate Change, the total energy potential and the environmental benefit of mitigating CO2emissions in place of coal were preliminarily calculated to be around 1,920 TJ and 4.1 × 107kg, respectively, based on the certified volume of scrap tire and its energy use proportion in 2009.

Oceanic top predators, the marine ecosystems that support them and dependent socio-economic systems have been the subject of studies by researchers under the Climate Impacts on Oceanic Top Predators (CLIOTOP) regional programme since 2005. Research conducted under the programme has focused on how climate change is affecting the pelagic ocean, with a range of impacts detected or predicted for open ocean biology, and provision of ecosystem services such as food. Research has also focused on exploring the socio-economic consequences of oceanic change, and in some cases, evaluating the adaptation options that can reduce the vulnerability to climate change. In this special issue, 18 papers arising from the 4th CLIOTOP symposium, held in Keelung, Taiwan Republic of China in October 2018, report on a wide range of predator responses to historical climate variability, and changes in marine systems associated with climate change and commercial fishing. They describe new frameworks and approaches for understanding the population and spatial dynamics, trophodynamics, and future distributions of a range of species as well as identifying individual drivers of change and future risks to populations. Several contributions further our understanding of the trophic linkages between prey and predators and the pathways through which the environment can influence predators. Research conducted through collaborations facilitated by CLIOTOP align with several of the goals set out under the 2030 Agenda for Sustainable Development and a number of the challenges identified as needing to be addressed in order to achieve the societal outcomes of the UN Decade of Ocean Science for Sustainable Development 2021–2030. Setting future research directions that maximise the potential of the network of scientists contributing to the CLIOTOP programme will assist in progressing the science required for achieving a sustainable future.

Fossil fuels have been heavily exploited since the Industrial Revolution. The resulting carbon emissions are widely regarded as being the main cause of global warming and climate change. Key mitigation technologies for reducing carbon emissions include carbon capture and storage (CCS) and renewables. According to recent analysis of the International Energy Agency, renewables and CCS will contribute more than 50% of the cumulative emissions reductions by 2050. This paper presents a new mathematical programming model for multi-footprint energy sector planning with CCS and renewables deployment. The model is generic and considers a variety of carbon capture (CC) options for the retrofit of individual thermal power generation units. For comprehensive planning, the Integrated Environmental Control Model is employed in this work to assess the performance and costs of different types of power generation units before and after CC retrofits. A case study of Taiwan's energy sector is presented to demonstrate the use of the proposed model for complex decision-making and cost trade-offs in the deployment of CC technologies and additional low-carbon energy sources. Different scenarios are analysed, and the results are compared to identify the optimal strategy for the energy mix to satisfy the electricity demand and the various planning constraints.

In Taiwan, mushrooms are an agricultural product with high nutritional value and economic benefit. However, global warming and climate change have affected plant quality. As a result, technological greenhouses are replacing traditional tin houses as locations for mushroom planting. These greenhouses feature several complex parameters. If we can reduce the complexity such greenhouses and improve the efficiency of their production management using intelligent schemes, technological greenhouses could become the expert assistants of farmers. In this paper, the main goal of the developed system is to measure the mushroom size and to count the amount of mushrooms. According to the results of each measurement, the growth rate of the mushrooms can be estimated. The proposed system also records the data of the mushrooms and broadcasts them to the mobile phone of the farmer. This improves the effectiveness of the production management. The proposed system is based on the convolutional neural network of deep learning, which is used to localize the mushrooms in the image. A positioning correction method is also proposed to modify the localization result. The experiments show that the proposed system has a good performance concerning the image measurement of mushrooms.
