    Africa

    If we call a significant yield increase in single crops a ‘green revolution’, then the first green revolution took place about 10 000–12 000 years ago, when humans started to cultivate land. This was also the beginning of civilization. Since then, humans have increasingly transformed the land and natural vegetation and have risen to be the main creators of the biogeosphere. Today, there is hardly any ecosystem around the globe that has not been influenced by humans.

    Sweden, Italy, Europe

    Europe is characterized not only by large geomorphological variability but also by a long history of land use. This resulted in a highly variegated landscape. Based on the IGBP‐transect initiative, a north south transect was established across Europe ranging from north Sweden to central Italy in order to study effects of global change. Mainly process oriented studies were established on plots along the transect, and these were used to establish functional relationships as basis for landscape integration.
