Which one of the following statements on biosphere reserves is not correct ?

The statement that Nanda Devi Biosphere Reserve is located in Madhya Pradesh is incorrect. Nanda Devi is located in the Himalayan state of Uttarakhand [c3][t4][t8]. In contrast, Madhya Pradesh hosts the Pachmarhi and Achanakmar-Amarkantak biosphere reserves [c3][c5]. Regarding the other options: UNESCO's Man and the Biosphere (MAB) Programme was officially launched in the early 1970s (sources vary between 1970, 1971, and 1972, but 1973 is often cited in specific contexts of program expansion) [c1][t2][t9][t10]. Biosphere reserves are indeed multipurpose protected areas designed to preserve genetic diversity and promote research on ecological conservation [c1][c4][t7]. They aim to reconcile the conservation of biological and cultural diversity with sustainable economic development through a scientific framework [t2][t10].
