These slides were presented at the 10th World Potato Congress, held in Cusco-Perú on May 27-31, 2018. They were presented during the In situ conservation challenges Technical Session. It presents a methodological proposal of the Project "Development of a methodology of prioritization of intervention areas for in situ conservation: case study of Solanum spp", funded by the Peruvian National Programme of Agricultural Innovation (Grant 167_PI). The project is lead by the Instituto Nacional de Innovación Agraria from Peru, in collaboration with Royal Botanic Gardens Kew.ABSTRACTCrop wild relatives are important sources of genes useful to improve domesticated species in the face of current global challenges. Conservation of these species can take two approaches: ex situ conservation in genebanks, or in situ conservation in their natural surroundings where they evolved and continue to interact with their environment. However, much efforts have focused on the first approach with many genebanks safely storing germplasm of crop wild relatives. Considering that Peru is the center of origin of potato, comprehensive strategies are needed to conserve that biodiversity in their natural environment. Here, we report on a methodology to identify high priority areas for in situ conservation of wild relatives of potato. Initially, we gathered all information available on the distribution of a previously defined list of species, in order to determine the reported distribution of each species. Secondly, we run species distribution models using climate and elevation as predictors in order to produce maps with the probability of occurrence of each species. Thirdly, we superimposed such maps, and combined them with potential threats to biodiversity in order to produce maps of priority areas for the conservation of wild potato species that maximize the chances of effective conservation. Finally, we cross checked such priority areas with other national protected areas, as well as the presence of local communities that can reinforce conservation activities. Overall, this methodology allows for the effective identification of priority areas for in situ actions for crop wild relatives’ conservation and can be transferable to other species. |
