The interest in renewable energy to replace fossil fuel is increasing as the problem caused by climate change become more severe. Small hydropower (SHP) is evaluated as a resource with high development value because of its high energy density compared to other renewable energy sources. SHP may be an attractive and sustainable power generation environmental perspective because of its potential to be found in small rivers and streams. The power generation potential could be estimated based on the discharge in the river basin. Since the river discharge depends on the climate conditions, the hydropower generation potential changes sensitively according to climate variability. Therefore, it is necessary to analyze the SHP potential in consideration of future climate change. In this study, the future prospect of SHP potential is simulated for the period of 2021 to 2100 considering the climate change in three hydropower plants of Deoksong, Hanseok, and Socheon stations, Korea. As the results, SHP potential for the near future (2021 to 2040) shows a tendency to be increased and the highest increase is 23.4% at the Deoksong SPH plant. Through the result of future prospect, we have shown that hydroelectric power generation capacity or SHP potential will be increased in the future. Therefore, we believe that it is necessary to revitalize the development of SHP in order to expand the use of renewable energy. Also, a methodology presented in this study could be used for the future prospect of the small hydropower potential.

Development of hydrogen utilisation for energy applications has seen promising innovation towards the future prospect of clean and sustainable energy, benefitting various aspects of environmental, social, industrial and energy security. In the APEC region, several economies, such as the USA, China, Australia, Japan and South Korea, have shown interest in the development of hydrogen technology for energy applications. These economies have been devoting effort towards research and development programmes, pilot projects and, up to a certain point, implementing it in their communities. In addition, these economies each have their own tailored hydrogen roadmap or strategy, ensuring a smoother path towards hydrogen development. In this mini-review, we analysed the approaches of three selected economies in the East Asia region towards hydrogen technology, namely China, Japan and South Korea. Each of these economies have their own strategies and priorities towards the application, production and future development of hydrogen technology. This review also analyses the future possibilities for the integration of hydrogen technology into various sectors, as well as various constraints faced by each economy. Therefore, the review might serve as a valuable reference towards the feasibility of future hydrogen technology development in the East Asia and APEC region.

In this review article, the current status of research on pier scour under waves is presented. This includes a summary of different bridge failure events due to scour, scour mechanism, scour depth predictors under waves, influence of pier shape on scour depth formation, shape of scour hole around piers, and many others. Further, this article describes the scour process, development of scour depth predictors, and the complexity involved in the scour related calculations. Finally, the future scope of research is delineated.

This paper uses STRIPAT models to find the impact of population, economy and technology on CO2 emissions of China. The result shows the impact of population, economy and technology on CO2 emissions are 1.253, 1.076, and 1.077 respectively. According to the future prospect of China, three scenarios of Chinas economic development are given to forecast the CO2 emissions, the forecasting results shows that if Chinas economic, population and energy consumption is increasing 7%, 0.4%, 5% every year, respectively. CO2 emissions will reach 21.05×108t in 2020. The CO2 emissions per unit GDP is decreasing by 45.54% in 2020 compared to 2005, which can fulfill the Chinese governments promise to decrease the GHG emissions per unit GDP by 40-45% in 2020 compared to 2005.

Should the same convergence criteria be applied to the countries that are relatively poorer in the region, or will the Commission try to revise the rules by request of the French and German governments? Due to the larger economies' economic under-performance in recent years, even the European Commission are taking account of the revision of some of the criteria. Are there any other possibilities except for the revision of the criteria? In this paper, we focus on the future prospect of the convergence criteria and suggest the possible scenarios for those questions.

A previous paper, developing the idea of automated routing of vessels stated ‘the full scope of automated systems at sea is inconceivable in terms of compliance with the old (collision) Regulations. Only an entirely new code of manœuvre will give the dimensions and scope needed.’ Again, it was suggested that the Collisions Regulations would need to be completely re-thought and re-written in the light of present capabilities and possibilities. This paper, while not endeavouring completely to re-write the Collision Regulations, tries to outline the form the new Regulations should take without entering into too much detail, with particular relevance to the traffic separation schemes presently under consideration by Imco and leading to the future prospect of complete automation as envisaged in the article under reference.
