The complex interplay between land use planning, water resource management, and the effects of global climate change continues to attract global attention. This study assessed the connection between land use planning, water resources, and global climate change. Data were collected using an online questionnaire that was emailed to 320 professionals in the land and environmental sectors in Greece and Europe. The results showed a significant relationship between land use planning, water resources, and their policies with global climate change. It was also revealed that proper land use planning can guide the establishment of waste management systems that minimize methane emissions, and that land use planning influences agricultural practices, which, in turn, impact greenhouse gas emissions. It was also revealed that changes in precipitation patterns can lead to an increased frequency and severity of droughts, and that changes in water temperature and flow can lead to habitat loss. This study also confirmed that strong policy support helps in the conservation of land and water resources, and stakeholder engagement promotes a shared planning process, leading to commonly agreed-upon spatial measures. This study recommends that governments and policymakers should integrate climate change, land use, and water management policies to ensure a coherent and effective approach towards sustainable development.

Climate change presents a pressing challenge to regional development, impacting economies, environments, and societies across the globe. Europe, with its diverse regions and commitment to sustainability, serves as a unique case study for exploring the integration of climate change strategies into regional policy and planning. The purpose of this study is to analyze the integration of climate change strategies into policy and planning for regional development in Europe, especially in Greece. Data was collected from 270 environmental experts across Greece using a questionnaire. The results highlight the significance of regional economic growth (gross regional product), infrastructure quality, educational attainment, and a conducive business environment as key measures of regional development. Opportunities arising from climate change strategy integration are explored, revealing economic benefits, environmental opportunities, social enhancements, and technological advancements. These opportunities not only mitigate climate change’s adverse impacts but also foster innovation, economic growth, and community resilience. Successful integration can position regions as global leaders in sustainability and innovation. Correlation and regression analyses reveal that opportunities for integration and common climate change strategies positively influence regional development, while barriers exhibit a counterintuitive positive relationship. However, several barriers hinder integration efforts, including institutional fragmentation, resource constraints, conflicting political and economic priorities, and insufficient stakeholder engagement. This study sheds light on the intricate relationship between climate change, policy integration, and regional development in Greece. It supports the potential for regions to drive sustainability and innovation while navigating the challenges of climate change, ultimately contributing to a more resilient and prosperous future.

In the market-shaping literature, markets are viewed as the results of intentional and planned acts. Market shapers do not often create technology themselves despite the fact that technical advancements can hasten changes in smart sustainable marketing. This study assessed the development of emerging technologies in business informatics with a focus on smart sustainable marketing and its relevant emerging technologies. Data were collected using an online questionnaire from 320 marketing professionals in Greece. The study revealed that emerging technologies have a significant relationship with smart sustainable marketing. Drivers of smart sustainable marketing positively enhance the effectiveness of smart sustainable marketing, and innovations in business informatics have a positive effect on smart sustainable marketing. It is clear from our results that the area of emerging technologies and smart sustainable marketing has not received much attention since such developments depend on complementary technologies that make it possible for emerging methods or technologies to integrate resources and co-create value. This study conceptually distinguishes between technology as a market offering and technology as a business platform for market shaping and innovation. Managers in the business industry and elsewhere are urged by this research to more closely examine the development of ancillary technologies, which could serve as platforms for market innovation and market shaping. Discovering and taking advantage of these opportunities is crucial for success in smart sustainable marketing. This study also presents a significant addition to the academic community because of the empirical evidence on the relationships between business informatics, smart sustainable marketing, and new technology. In terms of technology, it expands the theoretical framework of market dynamics and offers a novel perspective on the ways in which technology influences the structure and sustainability of markets.

This paper assesses the impact of Early Warning Systems (EWS) on minimizing loss of life during calamities using Greece case. EWS are useful in disaster risk reduction due to their ability to issue alarm, offer early hazard forecast, educate the public and use technology to enhance the response action. This study aims at evaluating the effectiveness of these six components through a survey of 353 environmental professionals and specialists in Greece. The results show that the Greek EWS tends to offer early warning in most events, which assists in preparing the community. But still, there are critics who argue that the effectiveness of the system is still lacking in delivering urgency of threats. Though they admit that they have a high level of confidence in their hazard predictions, there remain issues with reliability, which need to be worked on constantly to retain the public’s confidence. Although, increased public awareness and education activities have played a positive role in increasing understanding about the EWS, there are shortcomings existing in making sure that everyone realizes what steps they should take when they get a warning. Automated systems such as the IoT implemented to monitor hazardous events and AI integrated to forecast such events have made surveillance faster and more precise. However, access as a concept remains limited, especially for the sensitized population, and there is a need to adopt more inclusive methods of passing information. It also suggests the development of communication-Intensive EWS through the integration of mobile alerting, social media, and other community engagement programs. This study adds value to the existing body of knowledge and practice in disaster management by providing insights into factors that determine success of an EWS in reducing fatalities. Proposals include improving the communication of risks, improving the consistency of forecasts through the use of AI, focusing on more education among the public and spending on improved systems for monitoring. Better communication with relevant authorities and harmonizing of technology-enhanced solutions will provide more efficient and coherent disaster management in areas such as Greece and other high-risk regions.
