Global Climate Change Impacts on Crop Production in Hungary

Global climate change is one of the major issues today. Th ere is a continuous rise in temperature escorted by the increasing frequencies of weather anomalies. In Hungary two facts can be observed: the ascending levels of temperature rise, with a magnitude of 1 oC and the annual precipitation decrease. Human activities are signifi cantly altering the natural carbon cycle. Long-term rise in atmospheric CO2 aff ects crop production regarding both adaptation and mitigation. Th e negative eff ects of climate change can be limited by changing crops and crop varieties, improved water management and irrigation systems, adapted plant nutrition, protection and tillage practices, and better watershed management and land-use planning. Th e global potential of carbon sequestration through crop production, land use and soil management practices may off set one-fourth to one-third of the annual increase in atmospheric CO2
