Innovation for Sustainable Cities and Societies

The urbanization reality has brought to light numerous challenges demanding a shift towards sustainability, with approximately 3 million people migrating to cities every week, and by 2050, 68% of the global population will reside in urban areas. Greening our urban landscapes is essential, but true sustainability extends beyond aesthetics. Neglecting this integral aspect can result in negative externalities, including increased energy consumption, contributing to climate change. In pursuit of a sustainable society, the happiness and well-being of citizens must be central to our efforts, much like nature’s balance. Sustainable cities are those that combine environmental resilience with social well-being. However, theory alone will not suffice; innovation is the catalyst for transformation. since the island is grappling with economic crises and imbalanced trade. Contribution to a circular economy can be done by adopting principles of green innovation and entrepreneurship. In conclusion, the imperative for innovation in achieving sustainability for cities and societies is clear. By harnessing nature’s wisdom and fostering a culture of innovation, we can pave the way for a greener, happier, and more equitable future.
