Urban areas, central to human activity, face significant challenges from climate change and development, necessitating urgent action. The rise of smart cities, utilizing technology to enhance sustainability and quality of life, presents an opportunity to address these issues. This paper examines how future smart cities can leverage innovative technologies, stakeholder collaboration, and sustainable design to build resilient systems. These systems mitigate and adapt to climate challenges, promoting ecological balance and social equity. Key strategies include Vertical Green Structures (VGSs), renewable energy, and energy-efficient prefabricated housing. These homes feature radiative cooling coatings and Phase Change Materials (PCMs), reducing cooling loads by $7-17 \%$ across diverse Indian climates. The study underscores the importance of integrating technology and community engagement. This fosters sustainable urban growth amid climate unpredictability.
Lack of proper municipal solid management in the Northern provinces of Iran has led to damages to the natural resources, health, environment, social and economic conditions. Construction of solid waste processing plants such as compost and incineration, ignoring essential elements in waste management, cannot be as a successful strategy to solve the solid waste problems. Integrated management as a suitable and well-proved solution in many developed countries was proposed for Mazandaran province as a more reliable strategy to replace the existing conditions. In this paper, the results of study conducted for Amol and Noor region have been analyzed. Minimizing waste production, maximizing recycling and reuse, processing organic waste through digestion or composting process, producing refusing derived fuel (RDF) and using it in the waste incineration plants or Neka cement plant and finally disposing less than 10% of the waste in landfill is the proposed solution to improve the existing waste conditions. Implementing the proposed integrated management over a period of 20 years will lead to preventing from economic and environmental damages due to the loss of valuable natural resources and the release of various pollutants from landfills which is evaluated to be equivalent of about 28 billion dollars also, saving resources and energy estimated to be about 38 billion dollars.
In a previous paper, we discussed that the application of cost benefit analysis (CBA) often incurs setting a value to a statistical human life (VOSL). This led to decades of research into what a reasonable value should be. These evaluations of the VOSL lead to widely varying results. Rather than attempting to harmonize on an average with large margins of uncertainty, the conclusion can be drawn that indeed there is no law of nature that determines what risk is acceptable and that, therefore, a consistent valuation of a human life cannot be expected. Nor can it be expected that there is a universally valid number for the acceptability of a risk. We argue that one should accept that standardization of acceptable risks has its practical limitations given by the – lack of – similarity in nature of the activity and the nature of the risk. In fact, attempts to force standardization are counterproductive. In many cases, one has to accept the only available alternative not involving violence, which is a political debate, terminated by the more general rule of law or constitution on how to settle such a debate and then accept the decision.
