The range of genetic varieties and of cultural practices associated with rice have made the Jeypore tract a globally important reserve of genetic diversity and accumulated traditional knowledge of rice cultivation. 

Addressing a decline in genetic diversity asdfThe latter half of the twentieth century saw a rapid erosion of biological diversity in India. As a subset of biodiversity, agricultural biodiversity is under particular threat, with standardized crop varieties replacing native ‘landraces’ – local species varieties that have developed naturally through adaptation to their local environments. With the advent of India’s Green Revolution in the late 1960s, government agricultural extension agencies began introducing new rice varieties to improve production and productivity in tribal areas. In the process, local varieties were often replaced with high yielding varieties, eroding the rich genetic diversity of rice. Orissa was once the traditional home of the largest number of rice varieties of any state in India, with more than 1,750. However, by the 1990s, the number of local rice varieties had fallen to approximately 150.
