Chien Shun-yih looks out over his withering tea fields in Taiwan's picturesque southern Meishan township and lets out a sigh.

A once-in-a-century drought last year followed by torrential rain this year have decimated his crop and left Taiwan's tea farmers scrambling to adapt to the extreme weather changes.

"Climate is the thing we can least control in managing our tea plantation," said the 28-year-old Chien. "We really do rely on the sky to eat."
