The purpose of this study is to explore how digital construction policy (DCP) drives enterprise green innovation (EGI) from an information processing theory (IPT) perspective, including the mediating mechanisms of market information accessibility and operational risk, the moderating role of intellectual property protection (IPP) and product market competition (PMC) and the heterogeneous effects of ownership, Internet development and managerial ability.

Based on the matched panel data of A-share listed enterprises from 2011 to 2019 and the Broadband China policy as a quasinatural experiment, this study investigates the impact of DCP on EGI by constructing a multi-time point difference-indifferences (DID) model.

Digital construction policies can significantly promote EGI. DCP works in two fundamental ways, namely by increasing market information accessibility and reducing operational risk. IPP and PMC significantly increased the contribution of digital construction policies to EGI. Heterogeneity analysis found that digital technology has a stronger promotion effect for SOEs, high-managerial-ability enterprises and enterprises in regions with low Internet development levels.

The study provides new insights about the antecedents of EGI from a DCP perspective. It also enlightens emerging economies to actualize green innovation under the digital wave.

From the perspective of IPT, this study explains the mechanism of DCP-driven EGI. It enhances understanding of the relationship between DCP and EGI.

The Ruhr region is a long-term showcase for the implementation of nature-based solutions (NBS) as part of regional and local development policies. With the implementation of the Emscher Landscape Park and the ecological renewal of the Emscher River System, a fundament for new and integrated strategies and projects was created. The Ruhr Region was inspired by the models, strategies, and discussions of the EU to test and implement ES, NBS, and GI in the last 10 years. The planners were also following the two competing national discussions in Germany to interpret GI more in the context of sustainable urban development or more as nature protection and biodiversity. In 2016, the Ruhr Region published a first own GI strategy named Green Infrastructure Ruhr, which was designed as an integrated and multi-level strategy with five operative fields of action for the whole region: (1) Urban Landscape, (2) Water in the City, (3) Green Urbanism, (4) Climate-friendly Mobility, and (5) Climate Protection and supporting Energy Efficiency. The conceptional and political discussions about this approach in the region are still going on. The author recommends changing the perception of NBS from green conceptual and academic perspective to operative policy and management. NBS can be developed as real urban infrastructures. Our societies are well trained to run, to finance, and to maintain various infrastructure systems. It is time to take operative responsibility for NBS in our cities and regions.

This paper aims to advance the idea of sustainable flood reduction. Flood reduction through the use of the drainage system is considered an unsustainable approach that decreases the use of water. In contrast, the Water Sensitive City is a sustainable concept aimed at increasing the value of water for human needs and reduce flooding.

The current approach of relying on drainage systems is ineffective and must be combined with green infrastructures to reduce flooding. Green infrastructures can increase infiltration rates or facilitate rain harvesting. The study developed four scenarios that combine green and grey infrastructures and used the Soil and Water Assessment Tool (SWAT) model to select the most effective scenario based on the remaining amount of flood volume in every scenario.

Green infrastructures that are related to increased infiltration and rain-harvesting instruments reduced flooding by 22.3 and 27.7 per cent, respectively. Furthermore, a combination of the two types of green infrastructures reduced flooding up to 45.5 per cent. Conversely, applying only grey infrastructures (by increasing drainage capacity) to reduce the flooding to zero is unfeasible, as this requires more than double the current capacity. Therefore, a combination of green and grey infrastructures can significantly reduce flooding in a water sensitive and feasible manner.

Applying a combination of green and grey infrastructures is a new and effective approach to reduce flooding in the Kedurus Catchment Area.

Based on the 5th wave/tomorrow age theory, we are living in the world that is in necessity to change. Rapid urbanization causes global challenges such as economic problems and recessions, environmental challenges, climate change, social instability, health diseases, biological attached, and crisis caused by technological dominations. These challenges threaten the world, humanity, and human beings. Therefore, it is vital to tackle and struggle with them in order to maintain the world and improve quality of livability and quality of life to achieve sustainability. Generally, modern Blue-Green urban areas and smart cities with high quality of livability and life are proposed to deal with urbanization challenges to maintain the world and improve quality of human life. Based on Prof. Doost's 5th wave theory, related theories, concepts and models like Doost Risk Mitigation Method (DRMM), and also his experience on sustainability as best practice such as cooperating with Danish Sustainable Platforms Company, working as an academic leader at IoE/EQ EU Erasmus Plus project in Germany during 2017–2020, cooperating with former mayor of Copenhagen, consulting the German MV State Minister of Energy, Digitalization, and Infrastructure to cooperate with Iran in 2016, more than 15 years holding lecture and research internationally about risk and risk management on mobility in different universities like (TU Berlin) Technical University of Berlin (EUREF Campus, Sustainable Mobility Management and Sustainability Building) and also achieving a honorary doctorate in sustainable development management, a practical model concerned on risk management in mobility to provide comprehensive global Blue-Green clean sustainable urban mobility risk mitigation strategic plan is given. Therefore, in this chapter, impact of risk management on mobility to provide sustainable global urban mobility plan in order to create modern Blue-Green sustainable urban area and future smart cities through the 5th wave theory are explored. Fundamentally, the main goal of the research is to have an applied study about mobility risk mitigation and utilize it as a key to create comprehensive global urban mobility risk mitigation plan toward Blue-Green sustainable clean mobility technologies to create modern sustainable smart cities through the tomorrow age theory in order to create livable urban area with high quality of livability and life. In addition, the risks in mobility through the DRMM are measured to analyze the risk and to do risk mitigation and mobility project improvement to move to sustainable mobility and high sustainability in future smart cities.

The “renaturing” of cities through an increased emphasis on the use of nature-based solutions (NBS) potentially offers urban areas the opportunity to deliver multiple environmental and socioeconomic benefits. In particular, approaches linked to NBS can limit the degree of climate exposure and vulnerability impacting upon urban infrastructures. The success of NBS in addressing climate change pressures will require an improved understanding of the characteristics of environmental risk and the ability to evaluate alternate adaptive pathways. In response, this chapter explores those components which are central to effective urban infrastructure assessment and considers how they may assist in the formulation of infrastructure strategies.

We stress the need for an approach which is both scenario-focused and fully integrated within existing spatial planning frameworks. Here, we draw specific attention to the utility of strategic environmental assessment (SEA) in both embedding environmental evaluation within mainstream spatial planning and providing the basis for the comparative evaluation of alternatives. We also argue for an approach which recognizes areas of complementary interaction between “gray infrastructure” (whether existing or proposed) and approaches linked to NBS. In order to highlight examples of potential development responses, we draw on best-practice case study examples from the European Union (EU)–funded GROWGREEN project.

The technological revolution is fundamentally changing our lifestyle, work, and communication. There is still no accurate information about the future of this great transformation, but one thing is quite clear: the speed of the transformations in terms of scale and complexity, like a storm, will go through all aspects of a society's life and change all the current paradigms. One of the expectations from the fourth industrial revolution will be the expansion of smart cities in accordance with sustainable development criteria. In order for a city to be truly smart and innovative, city officials must pay attention to elements such as renewable and clean energy such as the internet of things, smart networks, smart parking, and smart transportation. In another sense, there must be a balance between economy, environment, and society in order to build a strong, sustainable, and flexible smart city that will survive the test of time. Of course, based on the 7PS model, the dimensions of culture and education are very important and fundamental for high sustainability. Researchers and those involved in the implementation of smart cities have explained the main indicators to identify these cities, which include some of the following items: For example, smart building, environmental protection, smart garbage collection, digitization of all government affairs and administrative work, widespread use of smartphones and electronic devices, complete, convenient, and universal access to the internet, car sharing service and online taxi. Other important indicators include the intelligentization of the traffic system and urban planning, citizen participation, economic ecosystem, optimization in electricity, water and energy consumption, development of electric and electric public transportation fleet, quality control and management, and reduction of air pollution. In this chapter, the theory of i-Sustainability Plus and i-Comprehensive Strategic Urban Plan is introduced as the beating heart of the ubiquitous blue-green smart city design. In such urban areas, it is all about the combination of real life, virtual reality, and in addition the future of clean technologies. In general, it can be said that sustainable smart cities are a solution to combat the challenges of urbanization.

The purpose of this paper is to investigate different types of innovations and their effects on eco-innovation practices by firms practicing green technology in Malaysia.

This paper collected data via postal and online surveys. The population frame for this study was obtained from the External Trade Development Corporation directory 2010 and the MyHijau Directory published in 2013. Surveys were distributed to the top management of green technology companies.

Based on the reflections from the managers who participated in the survey, this study found that environmental compliance has become a critical issue and lack of enforcement can no longer be ignored. Despite that fact that eco-innovation inspection activities to comply with environmental regulations are carried out periodically by the studied firms, the challenges in deploying the latest green technologies and their potential benefits have remain evident. Often, a shortage of resources has restricted firms in setting up in-house research and development units.

The findings of this study lead to the suggestion that firms practicing green technology should engage in an information-sharing culture with key suppliers regarding the latest know-how and technological developments. Among the recommendations are that firms should engage employees, customers, suppliers and competitors through co-production. This engagement will help improve product marketability, lean production processes and the design of desired green products.

This study investigated the level of eco-innovation practices for each dimension of its construct and compared that level to the different stages of firm innovation. The results will fill in the gaps in the literature because previous studies only focused on theory testing and modelling of eco-innovation from a multidisciplinary approach.

The purpose of the article is to present some preliminary findings and discussions points from a symposium on Public Outdoor Spaces and COVID-19 organised in Wageningen, The Netherlands, in June 2021.

The article argues for a salutogenic perspective on infrastructure planning and design, dealing with the interplay between the ideas and practices of infrastructure planning and design and the outcomes of those ideas and practices for health.

Within that perspective, the coronavirus (COVID-19) crisis is seen as an opportunity to revive the importance of infrastructure in promoting health and well-being.

The salutogenic approach adds a much-needed new perspective on infrastructure planning and design, and also involves challenges both in research and practice, for the application of holistic principles to the design of new environments.

This paper aims to examine the alternative financing available for sustainable infrastructure development in Nigeria’s sub-nations. Specifically, the study question is: what financial vehicles do sub-nations seek most, and what are the underlying reasons for their preferences?

The study used a two-round Delphi method, using a questionnaire to gather data from high-ranking government officials in states that have localised sustainable development projects in Nigeria.

Results show that fundamental to sub-national sustainable infrastructure projects are federal allocations, pension funds, private equity, bonds and concessionary grants. Sub-nationals prefer these options, especially the emphasis on private equity, and the concessional funding through catalytic or blended finance because of their relatively lower or below-market interest rates.

The practical significance of this study is that the state’s policymakers can now identify appropriate strategies that enhance the shift towards these sustainable financing options, which will serve as a key catalyst in their 2030 and beyond vision to accelerate their state's infrastructure climate complaint. Equally, investors possessing funds with such attributes will gain an understanding of a prospective market within Nigeria’s sub-nation.

This study aims to improve the development of sustainable infrastructure in Nigeria’s sub-nations, which would have a beneficial effect on society by mitigating the effects of climate change.

The recommendations of this study can contribute to the development of innovative financial models for sub-national infrastructure development, thereby reducing reliance on revenue generated from fossil fuels.

This contribution aims to demonstrate that the adoption of a holistic approach to the development of infrastructures supporting the growth of cruise tourism can represent a trigger for a more sustainable urban and port planning in the Moroccan context. Although, along with this growth, there are global-local issues pertaining to sustainability and resilience that need to be addressed to support sustainable urban and social development of tourist cities.

Documents and literature review were used to develop an in-depth analysis related to the different fields involved in the proposed theoretical reflection. Scientific publications, data and international statistical reports have been used to validate the approach.

The work provides empirical insights to show the strengths of the country related to the sustainability, suggesting that they deserve to be integrated, involving urban planning, green energy transition, as well as the economic and social sustainability of tourism industry.

This paper aims to stimulate a debate among stakeholders and scholars involved on tourist port cities urban planning to avoid a “silos” approach and to favour a more sustainable infrastructure development process. In that sense, the paper fulfils the need to provide a basis to encourage the integration of different strategic topics and agenda concerning social and economic growth of tourist port cities.
