IN support of the United Architects of the Philippine (UAP) advocacy campaign in promoting and protecting the architectural profession, I am sharing some insights on how architects can contribute in creating a sustainable and resilient built environment for the benefit of society and Mother Earth. As the global population living in cities will increase to 66 percent by 2050, it is predicted that rapid urbanization, overcrowding and other related urban problems would worsen. With these pressing challenges, coupled with climate chage issues, sustainability and resilience have become cutting edge in design practices. Architects have an important role in responding to the complex challenges of the built environment by designing building and cities that adapt to time and the changing climate.
