| Description | Climate change affects the distribution of many species, including Burgundy and Perigord truffles in central and southern Europe, respectively. The cultivation potential of these high-prized cash crops under future warming, however, remains highly uncertain. Here we perform a literature review to define the ecological requirements for the growth of both truffle species. This information is used to develop niche models, and to estimate their cultivation potential in the Czech Republic under current (2020) and future (2050) climate conditions. The Burgundy truffle is already highly suitable for cultivation on similar to 14% of agricultural land in the Czech Republic (8486 km(2)), whereas only similar to 8% of the warmest part of southern Moravia are currently characterised by a low suitability for Perigord truffles (6418 km(2)). Though rising temperatures under RCP8.5 will reduce the highly suitable cultivation areas by 7%, the 250 km(2) (3%) expansion under low-emission scenarios will stimulate Burgundy truffles to benefit from future warming. Doubling the moderate and expanding the highly suitable land by 352 km(2) in 2050, the overall cultivation potential for Perigord truffles will rise substantially. Our findings suggest that Burgundy and Perigord truffles could become important high-value crops for many regions in central Europe with alkaline soils. Although associated with uncertainty, long-term investments in truffle cultivation could generate a wide range of ecological and economic benefits. |
