Last morning in Vietnam was a rickshaw ride to a silk weaving factory, followed by a rattan mat weaving factory, then across to one of the islands in the river. This used to flood every year, but hydro schemes upstream have stopped that. While the flooding seems to be a pest, they were mostly set up for it, building their houses on concrete or wooden stilts 3m off the ground, but now their fields are no longer refreshed by centimeters of fertile mud each year. And they are now short of water, though I'd have thought they could pump it from the adjacent river.
About to leave Vietnam for Cambodia. Been floating on the border for 3hrs now.
