Andalusia, Spain Lithograph Answers Why are there fewer crops on this side of the river? The area on this side of the river is part of Donana National Park. It is bordered on the east by the Guadalquivir River and on the west by a much smaller river, the Rio Brazo de la Torre. The region is part of one the largest and best-known wetlands in Europe. Almost half the reserve area comprises swamps on flat clay soil filled with muddy sediments. Fewer crops exist on this side of the river because of the poor agricultural conditions and also because the area is strictly protected. Why is the river water brown? The river water is brown because it contains high levels of sediment from the surrounding area. This can be caused by heavy erosion of the riverbed, riverbanks, and channel. It could also be the result of substantial rainfall, which can wash topsoil and other types of material into the river. Why are these fields different sizes? The fields are different sizes because they are different crops. The larger fields are most likely grape vineyards. Andalusia is world-famous for its production of Sherry, a type of wine produced from Listan and Pedro Ximenez grape varieties. The smaller fields are presumably strawberries, oranges, and almonds, which are the main crops grown in this region. Their conditions for ideal growth differ, and inevitably so do their acreage.
