Abstract

Global climate change is one of the major issues today. There 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 Celsius and the annual precipitation decrease. Human activities are signii cantly altering the natural carbon cycle. Long-term rise in atmospheric CO(2) affects crop production regarding both adaptation and mitigation. The negative effects 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. The global potential of carbon sequestration through crop production, land use and soil management practices may of set one-fourth to one-third of the annual increase in atmospheric CO(2).
