Abstract

Agriculture is highly affected by climate change. Climate change impacts may influence almost all fields of agricultural activities; production efficiency, quantitative and qualitative deterioration of crop yields produced for alimentary purposes, and determine post-harvest manifestation of agricultural products inducing hazard in the field of food safety, transport, storage and distribution. Soil-climatic conditions, amount and distribution of precipitation, anomalies and extremities of temperature as well as various manifestation of air movement from stand still to storms are some of the main factors that may influence agriculture. Pollution has been considered solely as the presence of unfavourable alien matter in the environment, but in reality pollution is far more than that. Agri-environmental pollution is largely independent of mankind, since many pollution or degradation processes may begin with no direct relationship to human activities. Soil degradation, or irreversible damage to natural ecosystems by climatic factors (drought, flood, water logging, salinity) are the most frequent consequences. Biological pollution, like weed infestation, epidemics and gradations, pollen allergy, the poisonous effect of mycotoxins on farm animals and humans, new pests and diseases, the emission of greenhouse gases, and biological factors which cause quality deterioration represent an increasing pressure on agri-environment. This paper is intended to give an overview of some research activities and their results in relation with climatic aspects of agri-environmental pollution in Hungary.
