Strung along the coast of southern Thailand is a line of small fishing towns, nestled between the rugged beauty of the Tanaosri Mountains and the once-abundant waters of the Gulf of Thailand. For centuries, the people of Prachuabkirikhan ["the city in the mountains"] have enjoyed a simple lifestyle of hard work, living from the riches of the ocean and their farmlands.

But this idyllic existence - which attracts tourists looking for a laid-back beach holiday far from the bars and nightclubs of the big resort towns - may soon vanish as the province is hammered on two fronts, by climate change and rampant overfishing.
