Abstract

Changing climate affects ecosystems in a variety of ways. As each species responds to its changing environment, its interactions with the physical world and the organisms around it change too. This A significant attention is paid to how changes in seasonal and annual precipitation sums affect ecosystems. Argentina does not escape the phenomenon of global climate change, in which numerous local references have reported the change rainfall patterns in different regions within the country. Studies that have not yet been published for the province of Entre Ríos (Argentina) are being carried out, which have allowed to demonstrate a change in the variation of monthly, seasonal and annual rainfall. The partial results confirm a sustainable increase in annual precipitation, with the 1970s being a significant breaking point. These changes have caused easily observable modifications in some of the components of ecosystems, for example: the soil and vegetation. In this manuscript the effects of climate change and a case study corresponding to typical agroecosystems of southern South America were presented. In a climate change scenario, local information is crucial to understand what the magnitude is and how the effects can be mitigated.
