This chapter describes the main physical characteristics of the Ebro River, including the watershed orography, the biogeography and vegetation, the climatic and hydrological characteristics, and the soil type and biogeochemistry of river Ebro waters. The Ebro watershed has historically served as nucleus and connection for humans human settlements are known since pre-historic years and nowadays the river water chemistry cannot be understood without the anthropogenic effects. Therefore, the potential effects of human activities at the Ebro watershed are analyzed.

During the history of the human settlement in the Ebro basin, the river channel has played an important role as a frontier line but also as a communication line. The Ebro River basin was a crucial scenario for hard and bloody battles, such as the Ebro battle which occurred at the lower part of the Ebro basin During the Spanish Civil War (1936-1939). Hydrology played a military role during this battle, with sudden openings of upstream dams in order to interrupt the crossing of the infantry. 

In this way, Crosby demonstrates that environments and societies create one another, or more abstractly, they are mutually produced. The success of grasses depends on the success of the human settlement efforts that surround them, and vice versa. While these introduced Old World grasses benefited from European behaviors (grazing, and so forth), so too, settlers catered to the needs of the grasses, by planting and weeding, and animal grazing as they went.

Because of their position between the upland drainage and the sea, it is reasonable to suppose that estuaries have always been subjected to appreciable loadings of nutrients and other weathering products from their watersheds. However, various other features of estuaries (fisheries, commerce, etc.) have also long made them attractive for human settlement, with the result that a far larger anthropogenic input of nutrients, heavy metals and other pollutants has often been superimposed on an already rich background.

Forestry Indigenous types, minimal deforestation Gradual disappearance of community and individual forests as a result of indiscriminate cutting to pave way for additional land for cultivation, charcoal burning and even for human settlement Tremendous deforestation due to rapid population increase that required more land and cheaper energy sources Tremendous deforestation with concerted efforts for reforestation /afforestation. Hence the introduction of the Shamba system and environmental day trees are planted on public land and farmers encouraged to plant also on their farms...
