== Seed banks classification == Seed banks can be classified in three main profiles: assistentialist, productivist or preservationist. In practice, many seed banks have a combination of these three main types, and they may have different priorities depending on the context and goals of the seed bank.<ref>{{Cite journal|last1=Pellegrini|first1=Pablo A.|last2=Balatti|first2=Galo E.|date=2016-12-01|title=Noah's arks in the XXI century. A typology of seed banks|journal=Biodiversity and Conservation|language=en|volume=25|issue=13|pages=2753β2769|doi=10.1007/s10531-016-1201-z|bibcode=2016BiCon..25.2753P |hdl=11336/46868 |s2cid=2545366|issn=1572-9710|hdl-access=free}}</ref> # Assistentialist seed banks: These seed banks primarily aim to support the needs of local communities and small-scale farmers. They focus on providing seed samples that are well-suited to local conditions and are easy to grow and maintain. They prioritize seed samples that have high yield potential, are pest and disease resistant, and can be grown with minimal inputs. # Productivist seed banks: These seed banks primarily aim to support large-scale agricultural production and commercial farming. They focus on providing seed samples that have high yield potential, are pest and disease resistant, and can be grown with minimal inputs. They prioritize seed samples that are well-suited to large-scale mechanized farming and can be grown in large quantities. # Preservationist seed banks: These seed banks primarily aim to conserve the genetic diversity of wild and domesticated plant species. They focus on preserving the genetic diversity of plant species, and make seed samples available for research and breeding programs. They prioritize seed samples that are rare, endangered, or have unique genetic characteristics. {| class="wikitable" width="100%" |+Seed banks classification by profile !width="10%"|Profile !width="30%"|Assitentialist !width="30%"|Productivist !width="30%"|Preservationist |- !Objective |Conserve varieties of seeds in case they need to be used in coming harvests |Conserve varieties of seeds to contribute to the improvement of current crops by crossing them with those seeds |Preserve varieties of seeds in case they are destroyed by either man or natural events. |- !Functioning |The bank provides seeds to farmers who lack them |The bank makes its seeds available to produce new crops of agricultural interest from these seeds |The bank does not offer its seeds but it safeguards them |}
