CWR checklist and priority taxa of South Africa

The dataset includes an annotated checklist of 1593 food and fodder crop wild relatives (CWR) existing in South Africa, with taxon information, related crop, distribution and red list status. In a separate sheet are listed 258 CWR that have been prioritized for conservation based on socio-economic value of the related crop, potential for crop improvement, threat status, distribution and occurrence status

South Africa

South Africa has the second longest coastline on the African continent and spans two oceans. The confluence of the Benguela and Agulhas Currents off South Africa results in their dynamics being complex and often unpredictable, although it is these dynamic ocean systems that contribute to the high biodiversity and productivity of the South African coastal and marine ecosystems. There are 136 different habitat types ranging from subtropical coral reefs and mangroves on the north-east coast to temperate kelp forests and seamounts on the south and western coast. These habitats are under pressure from climate change as well as direct human impacts. Climate change is expected to influence the dynamic nature of the ocean systems through alterations of the currents, sea-level rise and increased water temperatures, ocean acidification, and storm events. Human activities such as fishing, overexploitation of marine resources, and coastal development have placed great pressures on marine and coastal habitats, biodiversity, and resources. Future threats include increased offshore mining activities in habitats that are not well studied or protected. Marine protection and management is achieved through the overarching National Environmental Management and Integrated Coastal Management Acts, which make provision for setting up marine protected areas (MPAs) and protection of individual species. Operation Phakisa is an exciting new initiative that has the potential to address the human resources capacity shortages, research requirements, and governance issues identified in this chapte
