Abstract Solar photovoltaic (PV) energy is one of the fastest growing renewable energy sources globally. However, the dependency of PV generation on climatological factors such as the intensity of radiation, temperature, wind speed, cloud cover, etc can impact future power generation capacity. Considering the future large-scale deployment of PV systems, accurate climate information is essential for PV site selection, stable grid regulation, planning and energy output projections. In this study, the long-term changes in the future PV potential are estimated over Australia using regional climate projections for the near-future (2020–2039) and far-future (2060–2079) periods under a high emission scenario that projects 3.4 °C warming by 2100. The effects of projected changes in shortwave downwelling radiation, temperature and wind speed on the future performance of PV systems over Australia is also examined. Results indicate decline in the future PV potential over most of the continent due to reduced insolation and increased temperature. Northern coastal Australia experiences negligible increase in PV potential during the far future period due to increase in radiation and wind speed in that region. On further investigation, we find that the cell temperatures are projected to increase in the future under a high emission scenario (2.5 °C by 2079), resulting in increased degradation and risks of failure. The elevated cell temperatures significantly contribute to cell efficiency losses, that are expected to increase in the future (6–13 d yr−1 for multi-crystalline silicon cells) mostly around Western and central Australia indicating further reductions in PV power generation. Therefore, long-term PV power projections can help understand the variations in future power generation and identify regions where PV systems will be highly susceptible to losses in Australia.

Estimation of satellite-based remotely sensed evapotranspiration (ET) as consumptive use has been an integral part of agricultural water management. However, less attention has been given to future predictions of ET at watershed-scales especially since with a changing climate, there are additional challenges to planning and management of water resources. In this paper, we used nine years of total seasonal ET derived using a satellite-based remote sensing model, Mapping Evapotranspiration at Internalized Calibration (METRIC), to develop a Random Forest machine learning model to predict watershed-scale ET into the future. This statistical model used topographic and climate variables in agricultural areas of Lower Yakima, Washington and had a prediction accuracy of 88% for the region. This model was then used to predict ET into the future with changed climatic conditions under RCP4.5 and RCP8.5 emission scenarios expected by 2050s. The model result shows increases in seasonal ET across some areas of the watershed while decreases in other areas. On average, growing seasonal ET across the watershed was estimated to increase by +5.69% under the low emission scenario (RCP4.5) and +6.95% under the high emission scenario (RCP8.5).

In recent years, with the advancement of the “The Belt and Road”, the cooperation between China and ASEAN countries is increasingly close, and the cross-border exchange of education between China and ASEAN has been further promoted. This article will research targeted at undergraduate animation education in Thailand. By studying the current educational pattern of the animation major in Thai universities and exploring the roots of the existing issues, combining the characteristics of the animation major in the College of Chinese & ASEAN Arts, try to put forward some ideas for the construction of a collaborative cultivating curriculum system for Chinese and Thai undergraduate talents. In order to provide some useful thoughts for the future development of international educational cooperation based on the College of Chinese & ASEAN Arts.

This concluding chapter explores the implications of the theory for great power politics as China continues to rise in the twenty-first century. If significant quantities of Persian Gulf oil could be realistically transported overland, away from U.S. naval interference, then the future threat to Chinese imports would remain low. Combined with a petroleum deficit that is likely to be large, Chinese coercive vulnerability could be held to a moderate level. Moderate coercive vulnerability should induce China to pursue indirect control as it emerges as a great power. Thus, the theory predicts that China is likely to eventually forge alliances with major oil-producing countries and transit states to keep oil in “friendly hands.” As yet, China is too militarily weak to shield friendly oil-producing states from interference by the United States or other potential rivals, but the beginnings of an alliance-based strategy appear to be taking shape under the auspices of the Belt and Road Initiative (BRI), described by some analysts as a nascent framework for twenty-first-century Chinese grand strategy.

Globalisation contributed to the economic, social, political and cultural development of the deve- loped and developing countries. At the same time, it had an adverse effect, which is in-creasing disparity of income between various social groups and countries. The continuation of such process will lead to the weakening of globalisation, so there is a need to transform globalisation. According to the Author, the initiative of China, entitled: New Belt and New Road is an example of such actions and will contribute to giving new impetus to the process of globalisation in the future. <b>Globalization is now facing one of the biggest challenges in the history: British exit from the EU (Brexit), USA’s quit from the Paris Agreement on climate change, USA also quitted from TPP agreement as well as from UNESCO. People start worry about the next moves of globalization. Therefore, we need to discuss the future of globalization seriously. </b> Clearly, globalization brought very positive impact on economic, social, political and cultural developments for all the countries including the developed as well as developing economies. However, globalization also brought some negative effects, such as the income disparity among different groups of people and different countries. It has been continually enlarging, not narrowing down in the process of globalization. How to deal with the continual globalization? Of course there are different ways. We have been seeing the rising of the nationalism, the protectionism in some of the countries, we have been seeing withdraws of some countries from the global governance institutions. At the same time, we find that China has been making great efforts not only pushing forward the continual globalization but also trying to transfer the old style globalization to the new style globalization which is what I called the transformation of globalization in the new era through the Belt and Road Initiative.

This chapter discusses China’s changing attitude, doctrine, and policy actions towards international order and offers some tentative findings on the complexity of China’s role in the struggle over the future of international order. This complexity results from China’s efforts simultaneously to consolidate its presence in the existing international order but also to reform existing global governance institutions. The ambition to seek an alternative international order makes it, at least to some extent, a revisionist state. While pursuing an agenda to reform the existing international order from within, China additionally has begun to sponsor an unprecedented number of new international institutions and initiatives of its own, such as the Asian Infrastructure Investment Bank (AIIB) and the Belt and Road Initiative (BRI). How this will play out will depend above all on the interaction of China with a USA still wedded to its hegemonic role in world politics.
