Initially, protected areas had a single, major aim which was to protect biodiversity; today, by contrast, the promotion human well-being is also an important aim. The relationship between the environmental conservation and its socioeconomic and cultural impact has been fiercely debated. Urdaibai in the Basque Country was designated a biosphere reserve in 1993, and certain activities were banned and resource exploitation was restricted, which has been hotly debated among locals. Many Urdaibai inhabitants do not agree with the restrictions, whereas others feel that the measures do not go far enough to guarantee conservation.
