Przestrzenne zróżnicowanie ENSO

The paper offers information about the spatial diversity of the El Niño Southern Oscillation (ENSO) in such aspects as the spatial range of the phenomenon and its varying impacts on agriculture, i.e. plant cultivation and fishery. The author discusses both positive and negative consequences of the El Niño and La Niña phases. The nature of the phenomenon underpins the author's analysis of the region. Theoretically, the criterion for the differentiation of an impact region is the existence, within its territory, of a relationship between specific phenomena (in this case, natural phenomena and human agricultural activity), and the relevance of a given criterion is crucial for a problem at hand. Such a condition is fulfilled by areas with anthropogenic activity which are significantly subject to the ENSO influence. This approach is related to the research concept proposed by regional geography (Dumanowski 1981), which revolves around the relationships between the environment and man.
