Climate change brings an uncertain future to one of the world's finest teas
PASSARA, Sri Lanka --In his tea garden up on the mountain, Piyasena Rajapakshe, 71, started his morning exercise by clouting tea bushes. He clouted here and there. Suddenly, one stalk fractured. Rajapakshe peeled its bark and found a black beetle as tiny as a sesame seed hidden inside. As an experienced tea grower, Rajapakshe knows how to find these undesired visitors, but he doesn't know why they showed up at this time of the year. The expanding presence of the pest is just one of many surprises to greet Rajapakshe as temperatures, dry spells and rainfall have changed here and in many other Sri Lankan tea gardens.
