The impetus for conservation has been inspired by several recent global initiatives such as the Convention on Biological Diversity (CBD), the UNCED and more recently, the Global Plan of Action and the International Treaty on Plant Genetic Resources for Food and Agriculture. Traditionally, conservation of genetic resources has primarily been through ex situ conservation. However, there is increased realisation that this method of conservation is not sufficient for the adequate conservation of the various gene pools due to increased and diversified user demands and requirements. The CBD and the Global Plan of Action have specifically called for both in situ and ex situ conservation measures for biodiversity and genetic resources conservation. The decision on the choice(s) of conservation methods is not only a matter of available technology and resources but it is also influenced by biological, economical, management, socio-economic, cultural and political considerations.
