Over the last few decades, various innovative technologies have emerged that have significantly contributed to making life easier for humans. Various information and communication technologies (ITCs) have emerged as a result of the global technological revolution, including big data, IoT, 4G and 5G networks, cloud computing, mobile computing, and artificial intelligence. These technologies have been adopted in urban planning and development, which gave rise to the concept of smart cities in the 1990s. A smart city is a type of city that uses ITCs to exchange and share information to enhance the quality of services for its citizens. With the global population increasing at unprecedented levels, cities are overwhelmed with a myriad of challenges, such as the energy crisis, environmental pollution, sanitation and sewage challenges, and water quality issues, and therefore, have become a convergence point of economic, social, and environmental risks. The concept of a smart city is a multidisciplinary, unified approach that has been adopted by governments and municipalities worldwide to overcome these challenges. Though challenging, this transformation is essential for cities with differing technological and social features, which all have the potential to determine the success or failure of the digital transformation of cities into smart cities. In recent years, researchers, businesses, and the government have all turned their attention to the emerging field of smart cities. Accordingly, this paper aims to represent a thorough understanding of the movement toward smart cities. The key themes identified are smart city definitions and concepts, smart city dimensions, and smart city architecture of different layers. Furthermore, this article discusses the challenges and some examples of smart cities.

To this day, conflicts have intensified between managers who want to preserve biosphere reserves and citizen who want to develop them. Based on this problem, this study seeks to investigate the establishment of a forum for communication between various stakeholders and to promote the economic development of local communities while preserving biodiversity. First, in terms of conservation, the results indicated that Gyeonggi Province and Namyangju City highly valued direct conservation activities in biosphere reserves, whereas Pocheon and Uijeongbu City highly valued indirect conservation functions through management or monitoring. Second, in terms of development, it was found that there were differences in the roles, perceptions and responsibilities with respect to biosphere reserves among the different layers of government: the central government agency, the Cultural Heritage Administration, the metropolitan government, Gyeonggi-do, and the local governments, Pocheon, Namyangju, and Uijeongbu. Third, in terms of logistical support, which serves as a function for communication and practical participation among management entities, the results suggested that it was necessary to establish a comprehensive decision-making organization for efficient management and operation and to provide opportunities for active participation. The study can be utilized as a basic reference for developing efficient communication by management entities in protected areas with similar challenges.

The rapid urbanization in many Asian countries has taken millions of people from the rural countryside to concentrated megacities, which eventually putting pressure on the existing water resources. The over-growing population and increasing living standard of people in the urban region of developed as well as developing countries such as Korea, China, Japan and India have witnessed a drastic change in terms of domestic water demand for the past few decades. In this study, we used the concept of potential surface water availability in the form of surface runoff for future vulnerability assessment. We focused on 42 megacities having population more than 5 million as per the United Nations (UN) census data 2020. The study shows that 30 out of 42 cities having more than 180L/p/d demand for domestic use based on various references. We have predicted the domestic water demand for all the cities on the basis of current per capita demand up to 2035 using UN projected population data. We found that the projected water demand in megacities such as Seoul, Busan, Shanghai, Ghuanzou are increasing because of high population as well as GDP growth rate. On the contrary, megacities of Japan considered in our stud shows less water demand in future due to decreasing trend of population. As per the past records provided by the local municipalities/authorities, we projected different scenarios based on the future supply for various megacities such as Chennai, Delhi, Karachi, Mumbai, Shanghai, Wuhan, etc. We found that the supply to demand ratio of these cities would be below 75% for future period and if such trend continues then the inhabitants will face serious water stress conditions. Outcomes of this study would help the local policy makers to adopt sustainable initiatives on urban water governance to avoid the severe water stress conditions in the vulnerable megacities.

It is no news that Nigeria's infrastructure challenge is enormous. In the global ranking, Nigeria ranked low in quantity and quality of its infrastructural provision which has a great impact on the ease of business transaction. Low investments in transportation have brought about the current infrastructural deficit. Recently, the Nigerian government has made effort to address at least to some extent the infrastructural deficit through Public-Private Partnership, but this has not yielded the desired result. Moreover, the sustainability issues relating to railway projects such as, emissions, noise pollution, ecosystem, and other environmental issues calls for urgent attention. Hence, this necessitated consideration on sustainability appraisal for the Chinese rail project in Nigeria. This study reviews sustainability of railway projects built by the Chinese firm in Nigeria with particular emphasis on the environmental and social impact of these projects. The study further identified issues and challenges in project implementation with a particular focus on civil dialogue and community engagements. A detailed literature search was conducted on railway projects and infrastructure by systematically reviewing selected published articles.The analysis of the selected articles identified sustainability issues and potential for improvement of Chinese railway projects and how they contribute to or inhibit competitiveness in the Nigerian railway market. From the literature searched, some of the projects constructed by Chinese firm revealed that there is economic and social impact of railway projects delivered by the Chinese firm in terms of capacity development and knowledge transfer potentiality. For instance, in the just concluded Lagos-Ibadan railway projects, the study gathered that the project brought about 5000 jobs and local staff were trained by the Chinese company, this will boost man power and local content capability. Also, it will significantly improve Nigeria's infrastructure and boost its economic development. The study suggests that Nigerian government should ensure and provide an enabling environment that is conducive for investment on the continent. Peace, improved security, and decent governance are the best conditions for sustainable transportation growth.

Wildfire disasters in the United States impact lives and livelihoods by destroying private homes, businesses, community facilities, and infrastructure. Disaster victims suffer from damaged houses, inadequate shelters, inoperable civil infrastructure, and homelessness coupled with long-term recovery and reconstruction processes. Cities and their neighboring communities require an enormous commitment for a full recovery for as long as disaster recovery processes last. State, county, and municipal governments inherently have the responsibility to establish and provide governance and public services for the benefit and well being of community members. Municipal governments' comprehensive and emergency response plans are the artifacts of planning efforts that guide accomplishing those duties. Typically these plans include preparation and response to natural disasters, including wildfires. The standard wildfire planning includes and outlines (1) a wildfire hazard assessment, (2) response approaches to prevent human injury and minimize damage to physical property, and (3) near- and long-term recovery and reconstruction efforts. There is often a high level of detail in the assessment section, but the level of detail and specificity significantly lessons to general approaches in the long-term recovery subsection. This paper aims to document the extent of wildfire preparedness at the county level in general, focusing on the long-term recovery subsections of municipal plans. Based on the identified challenges, the researchers provide recommendations for better longer-term recovery and reconstruction opportunities: 1) building permit requirements, 2) exploration of the use of modular construction, 3) address through relief from legislative requirements, and 4) early, simple, funding, and the aid application process.

The purpose of this study is to examine residents' perspectives on factors contributing to rural decline, including population decrease and landscape degradation, with the goal of proposing strategies to revitalize rural spaces in response to these challenges. After exploring rural decline issues in Jinan, a questionnaire was developed based on a review of existing research. Following this, participants were selected, and Focus Group Interviews(FGI) were conducted. Through the analysis of the findings, strategies for local revitalization were suggested in four sectors. Based on the research findings, there is a need to reassess public transportation and vacant property projects. On the social front, preventing the misuse of rural relocation policies and enhancing residential environments through spatial clarity are essential. Environmentally, clustering renewable energy and livestock facilities and attracting educational facilities are necessary to minimize disruption to rural landscapes. From a governance perspective, fostering entrepreneurship in rural tourism and business models utilizing the local landscape is crucial for an increase in regional visits. This study holds significance by emphasizing the practical situation of rural decline, steering away from resource-centric or business-focused policies. It underscores the potential usefulness of integrating this understanding into detailed planning within policies aimed at tackling rural decline.

호주, 캐나다 등에서는 우리나라와 달리 석재·골재를 광물자원 중의 하나로 취급한다. 이러한 이유로 지방의 주정부 단위에서 광물자원 및 지질정보를 취급하는 기관이 석재와 광물자원 관련 정보를 통합하여 제공하고 있다. 이들 국가에서 광물 및 석재·골재 자원과 관련하여 제공하는 정보는 인터랙티브 맵, 지질도, 탐사 데이터 셋, 3차원 지질모델, 광업권리, 광산 및 광산관련 보고서 또는 요약자료 등으로 지방정부 및 지질조사기관의 웹을 통해 이루어지고 있다. 반면 한국의 경우 국내 법률에 따라 석재·골재는 광물자원과 분리되어 별도로 관리되며, 이에 따라 관련 정보도 한국광해광업공단, 국토교통부, 산림청, 한국지질자원연구원 등 여러 기관으로 분산되어 관리되고 있으며, 통합된 정보를 제공하고 있지 못한 상황이다. 따라서 석재·골재 자원의 확보와 효과적 활용을 위한 종합정보관리체제의 구축을 위한 거버넌스 개편과 정보체계화 구축을 위한 정책 및 제도 개발이 필요한 상황이다.

산업혁명 이래 쓰레기 배출은 증가해 왔으며 폐기물의 처리 문제는 오늘날 인류가 직면한 가장 대표적 환경문제 중 하나가 되었다. 그러나 쓰레기는 님비 운동을 촉발하는 등, 처리 문제를 둘러싸고 다양한 국가, 정부 및 사회 주체들 간의 갈등은 고조되고 있다. 국가와 지방정부 수준에서 쓰레기 문제의 처리 방식으로는 제도, 법, 규제, 시장적 접근법, 합의와 협력적 거버넌스 등 다양한 방안이 도입, 적용되어 왔다. 최근에는 순환 경제라는 개념 하에 과학 기술을 적용하여 폐기물을 재활용, 재자원화하는 등의 방안도 주목받고 있다. 그러나 쓰레기 문제 해결을 위한 사회적 지지는 여전히 불충분하며 이에 새로운 접근법과 대안 모색이 필요한 시점이다. 본 논문은 훈데르트바서라는 예술가가 설계한 오스트리아 수도 빈의 슈피텔라우 소각장과 일본 오사카의 마이시마 소각장을 사례연구(case study) 하였다. 이들 사례는 오스트리아 출신의 훈데르트바서가 예술과 기술의 창의적, 혁신적 융합을 통해 어떻게 폐기물과 같은 도시 환경문제이자 공공의 문제에 대한 새로운 대안과 접근법을 제시하였는지 보여준다. 이들 사례는 오늘날의 환경문제 해결에 있어 과학기술적. 경제적 접근법과 더불어 예술과 문화의 융합이 유용할 수 있음을 시사한다.

Otters, designated as Class I endangered wildlife due to population declines resulting from urban development and stream burial, have seen increased appearances in freshwater environments since the nationwide ban on stream filling in 2020 and the implementation of urban stream restoration projects. There is a pressing need for scientific and strategic conservation measures for otters, an umbrella and vulnerable species in aquatic ecosystems. Therefore, this study predicts potential otter habitats using the species distribution model MaxEnt, focusing on Hwangguji Stream in Suwon, and proposes conservation strategies. Otter signs were surveyed over three years from 2019 to 2021 with citizen scientists, serving as presence data for the model. The model's outcomes were enhanced by analyzing 'river nature map' as a boundary. MaxEnt compared the performance of 60 combinations of feature classes and regularization multipliers to prevent model complexity and overfitting. Additionally, unmanned sensor cameras observed otter density for model validation, confirming correlations with the species distribution model results. The 'LQ-5.0' parameter combination showed the highest explanatory power with an AUC of 0.853. The model indicated that the 'adjacent land use' variable accounted for 31.5% of the explanation, with a preference for areas around cultivated lands. Otters were found to prefer shelter rates of 10-30% in riparian forests within 2 km of bridges. Higher otter densities observed by unmanned sensors correlated with increasing model values. Based on these results, the study suggests three conservation strategies: establishing stable buffer zones to enhance ecological connectivity, improving water quality against non-point source pollution, and raising public awareness. The study provides a scientific basis for potential otter habitat management, effective conservation through governance linking local governments, sustainable biodiversity goals, and civil organizations.

최근 과학기술혁신정책은 그 목표와 영역이 확대되면서 사회 환경 복지 노동 에너지 등 다른 정책 분야와의 결합이 활발해지고 있다. 특히 이명박 정부는 "저탄소 녹색성장"을 주요 국정 과제로 제시하면서 그동안 개별적으로 진행되어 온 과학기술, 환경, 사회, 자원 에너지 등 관련 정책간의 연계 통합이 핵심 과제가 되고 있다. 정책통합은 본질적으로 서로 다른 영역에서의 정책을 하나의 정책으로 묶어주는 것으로 정책의 본질적인 특성인 복잡성 시스템적 특성을 실제 정책과정에 반영하려는 노력이다. 또한 정책통합 과정에서 장기적인 비전의 공유를 강조함으로써 정부 전체의 효율성과 목표달성에 기여하도록 하는 것이다. 향후 우리나라가 나아가야 할 미래를 종합적으로 준비 설계해 나가기 위해서는 미래 예측 기능 강화와 더불어 장기적인 미래상을 바탕으로 현재를 끊임없이 준비해 나갈 필요가 있다. 특히 최근 과학기술혁신은 모든 사회변화의 기반이 되고 사회문제를 적극적으로 해결할 수 있는 핵심요소로 등장하면서, 각 부처가 소관정책에 투입하는 과학기술적 정책수단에 대해 관련 부처가 공유하고 종합적으로 검토하며 필요시 조정 통합될 수 있도록 하는 새로운 정책적 접근이 요구된다. 이와 함께 각 부처에서 각개약진 식으로 진행되고 있는 개별적이고 파편화된 정책 중 공통적 요소는 통합적인 전략으로 묶어 낼 수 있도록 하는 '정책통합'을 정책과정에 반영하거나 조직적 접근을 추가하는 경우 국가 전체적 정책효율은 제고될 수 있을 것이다. 이러한 접근은 영국 호주핀란드 등 선진국에서 최근 도입하는 통합형 정부형태에서도 볼 수 있고, 1990년대 이후 등장한 환경정책담론과도 유사하다. 우리나라의 정책결정 문화의 틀에서 부처할거주의와 수직적 의사결정의 문제점을 극복하고 과학기술적 접근의 비중을 높이며 정책효율을 제고하는 방법으로 정책통합의 방법을 제시하고 이에 필요한 정책과제를 제시하였다.
