The cattle are often attacked and sometimes human by tigers such as in Sunderbans where encroachment and health of tiger comes into play. If a tiger is old or injured, it generally attacks the easier target, that's why you see many incidents of man-eating tiger in that areas.
Education of villagers about importance of forest and tigers is one of the measures taken to avoid these incidents.
P.S.- In Sunderbans, when people go out for fishing or hunting, as long as they are on land, they wear mask on back side of their head. It is a notion that tigers attack from the behind,.
