This chapter reviews the potential impacts of climate change on on-farm conservation of crop diversity and on the contribution that on-farm conservation can make to agricultural adaptation to climate change, and ask two questions: (1) How might climate change affect the viability of on-farm conservation of landraces in centres of crop diversity? and (2) How can on-farm conservation contribute to the adaptation of small-scale farmers to climate change?
This chapter discusses submergence tolerance as a response to flooding, focusing on rice as a model crop where progress was made in developing flood-tolerant varieties and where opportunities exist for further improvements through mining the enormous genetic diversity available in preserved collections worldwide. The impacts of climate change on rice in flood-prone areas are briefly described. The progress made in exploiting the genetic variation in flooding tolerance-associated traits is summarized for rice germplasm improvement to develop high yielding varieties for flood-affected areas and for areas where floods are expected to worsen with climate change. Future directions in flood tolerance research in rice to cope with climate change are also mentioned.
This chapter describes and discusses some of the initiatives and developments that make the world better prepared to respond to climate change in terms of plant genetic resources (PGRs). A broad overview is provided of important issues concerning conservation and use of PGRs, including conservation approaches, strategies and responses that become more relevant under the threat of climate change. An enormous amount of crop germplasm and wild relatives is conserved in genebanks around the world, as well as in situ. Although not all this conserved germplasm is equally characterized and evaluated, there is sufficient documented germplasm available to plant breeders that can be used to tackle the growing threat of global climate change.
This chapter provides an overview on food security today, how problems of food production will be exacerbated by climate change, and how, in the case of one crop (rice), access to and use of genetic resources have already begun to address many of the challenges that climate change will bring.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
