Changes in the intensity and frequency of occurrence of droughts in Poland (1891-1995)
Papers in global change IGBP, No.7
The identification and characterisation of dry spells was performed on the basis of a unified methodology taking into consideration atmospheric conditions, and the situation regarding surface and underground waters. Attention was paid to changes
in the intensity and frequency of occurence of this phenomenon in Poland. The general trend to the changes, was ascertained and a cyclical character or fluctuations to the phenomenon in the course of the analysed period sought.

Forests play a quadruple role in the processes of global change : 1) as a cause, a source of the emission of greenhouse gases (GHC), predominantly in result of deforestation; 2) as a victim of global climatic change, due to the increased sensitivity
of trees to pests and diseases; 3) as a benificiary of global changes thanks to the fertiliser effect; 4) as a remedy for global changes thanks to their ability to sequester carbon. The role of forests depends thus on methods of management and the ways
