Potentially huge golf developments may arise in China and India with their burgeoning wealth. We may run out of oil sooner than we have estimated, or terrorism achieve that effect, putting an end to the globetrotting golf industry, or even the 60-minute journey to the golf club. Global warming will have considerable affects on vegetation, including grasses. Rising sea levels will drown some courses. Increasing radiation may force a change of culture, people preferring to stay indoors rather than endure the sunlight - or will they play at night under floodlights.
I'm not suggesting that any of these things will happen, but what are the issues that will shape the future of golf - and architecture, in particular - over the next 50 years?
