This confirms my Sri Lankan bemusement at the term "temperate climate". The tropics can be a PITA in many ways, but they have no shortage of biomass. Subsistence gardens abound and are productive. Even more than in other gardens, the issue is less to make things grow, but to stop the wrong things from growing. It's hardly surprising if ancient jungle dwellers long ago to tilted nature's bounty in their direction.
But I do take exception to the somewhat hippy-dippy claim that ..."colonial, industrial societies" came from outside the tropics and tried "to practice monoculture, pastoralism, and urbanism within them." Those "evils" took place in the tropics for thousands of years before western colonialists turned up.
