Concerns over the erosion of agrobiodiversity date back to at least the 1930s, when scientists began collecting plant material from around the world to be saved and exchanged for agricultural proposes(veteto and Skarbo 2009).These concerns were given additional weight with the advent of the green revolution. In its drive to increase yields the green revolution sought to increase the yields of one or two strains of one or two crops what is known as"monoculture within monoculture. Yet, in promoting just a handful of food crops, the strategy came at the expense of biodiversity(Box 7.1)
