Decline in climate resilience of European wheat
25. 1. 2019 -
The current breeding programs and cultivar selection practices do not provide wheat with sufficient resilience to climate change. Furthermore, the response diversity of wheat, an important sign of its resilience, has worsened in most European countries in the last five to fifteen years. These findings, gathered with participation of scientists from Czech Republic, were published in the PNAS journal.
Researchers, including Miroslav Trnka and Jan Balek from the Department of Climate Change Impacts on Agroecosystems at Mendel University in Brno predict that greater variability and extremeness of local weather will lead to reduced yields in wheat and increased yield variability. Unless wheat varieties are improved, the result could be a market with greater speculation and price volatility, which may threaten stable access to food by the poor. This can turn enhance political instability and migration.
