In these places, roof gardens build out of local materials are most suitable. They are repair and maintained by the communities themselves. This is seen in places like India, St. Petersburg and Senegal. Infact, in Senegal people have devised a local solution using bricks and wooden box beds. In India too, the use of locally available cheap materials to create roof gardens is most successful. The “Doshi System” is offered as the most suitable method.
