I have come across a website about how Cuba survived its own "Peak oil crisis" in the 1990s known to Cubans as the "Special Period".
Cuba lost half its entire oil supply when the Soviet Union collapsed in the early 1990s. As a result industrial agriculture and transport collapsed and electricity became more erratic as a result of loss of oil to thermal power plants.
However the Cuban people are very ingenous. Here is a list of the successful measures they took to counter the Special Period.
Converted truck and trailer units into 300 seater buses known as "Camels"
Carpooled with cars having as many as eight occupants at a time
Use of horses and carts as taxis.
Walking, cycling and riding buses
Extensive Permaculture including rooftop gardens and raised beds on vacant lots.
Use of oxen rather than tractors and combine harvester.
Development of bio-fertilisers and pesticides rather than chemical stuff.
Localised electricity generation through the use of solar power.
Other positives include an increase in the number of tertiary institutions in Cuban rural areas in order to prevent people from moving about the country and using precious energy in the process and Cuba's ability to maintain its first class health system even during the darkest part of the Special Period and an improvement in Cuban people's diet with a more vegetarian bent to it.
I think New Zealand should adopt the Cuban model if push comes to shove.
