I have been staring at this image for a while. Multi-generational planning and building and tending to. It’s very beautiful, isn’t it! I found it here. The linked article is about a design book that contains this example.
One of the loveliest examples comes from one of the wettest places on Earth and one of the most ancient cultures — the Jaintia Hills of the Meghalaya region of Northern India, where during the monsoon season severe rains transform the hills into hunchback islands rising from the flood.
To traverse this Venice of the rainforest, generations of local Khasi people have developed a system of astonishing living bridges, made by training the aerial roots of the native rubber fig tree (Ficus elastica) along the trunk of a betel nut palm tree (Areca catechu) laid across the ravine.
The living bridges are a valiant antidote to instant gratification: It takes a decade of tending before a bridge can support human weight at all. But within a generation, by a slow-blooming miracle of growth, gravity, and devotion, each bridge can carry as many as fifty people at once. With every passing year, with every new generation trained in training the trees, the bridge grows stronger and stronger, its lifespan stretching into centuries, far outliving the first human hands that twined the first rubber fig roots.
Bridge building – the symbolic solution.
