While the news is full of problems and potential problems today, there are also many opportunities. The greatest hope is embedded within the concept of sustainability. Current large issues embedded within sustainability include changing security concerns and the need to engineer within ecological constraints. In a rapidly changing and urbanizing world, the provision of adequate and affordable architecture remains a key priority for all governments. Sustainability is a word that has many different meanings (Pezzoli, 1997). While some strive to define it, others, such as former Chief Science Adviser to the President John Gibbons, are comfortable with the multiplicity of meanings that have accrued to sustainability (Gibbons, 1998). As I envision it, sustainability has several key aspects. There are physical/engineering issues, environmental issues, economic issues, equity issues, and security issues. On the physical side the most fundamental issue is to provide basic services, such as food, water, energy, shelter, transportation, health care, and communication, to the world’s population. On the environmental side, most critical is the maintenance of ecosystem function. On the economics side, most critical is wealth creation since no one wants to live in poverty. On the equity side most important is the recognition of every other person as fully human, which is consistent with the principles set out in the International Declaration of Human Rights. Urban development should be guided by a sustainable planning and management vision that promotes interconnected green space, a multi-modal transportation system, and mixed-use development. Diverse public and private partnerships should be used to create sustainable and livable communities that protect historic, cultural, and environmental resources. In addition, policymakers, regulators and developers should support sustainable site planning and construction techniques that reduce pollution and create a balance between built and natural systems.
