A Vavilov Center (of Diversity) is a region of the world first indicated by Nikolai Vavilov to be an original center for the domestication of plants. [3] For crop plants, Nikolai Vavilov identified differing numbers of centers: three in 1924, five in 1926, six in 1929, seven in 1931, eight in 1935 and reduced to seven again in 1940. [4] [5]
Centres of Plant Diversity (CPD) was established in 1998 as a joint classification initiative between the World Wildlife Fund (WWF) and the International Union for Conservation of Nature intended to identify the areas in the world that are of the highest conservation value in terms of protecting the highest number of plant species.

A Centre of Endemism is an area in which the ranges of restricted-range species overlap, [1] or a localised area which has a high occurrence of endemics. [2] Centres of endemism may overlap with biodiversity hotspots which are biogeographic regions characterized both by high levels of plant endemism and by serious levels of habitat loss .
There is considerable genetic diversity within all food crop species, particularly in centres of origin, which are the geographical areas where species were originally developed. For example, the Andean region of Peru is a centre of origin for certain tuber species, and over 1,483 varieties of these species can be found there.
The Convention on Biological Diversity (CBD), known informally as the Biodiversity Convention, is a multilateral treaty. The Convention has three main goals: the conservation of biological diversity (or biodiversity ); the sustainable use of its components; and the fair and equitable sharing of benefits arising from genetic resources .
Crop diversity or crop biodiversity is the variety and variability of crops, plants used in agriculture, including their genetic and phenotypic characteristics. It is a subset of a specific element of agricultural biodiversity .

The Wits Centre for Diversity Studies (WiCDS) was launched in 2014 and is based in the Faculty of Humanities at the University of the Witwatersrand (Wits). [1] Initially started as Intercultural and Diversity Studies of Southern Africa (iNCUDISA) at the University of Cape Town, [2] WiCDS was then established at Wits in 2014 and aims to build capacity to meet the challenges of diverse societies ...
