| Zusammenfassung |
| Erosion is highly associated to activities related to Agriculture. Because, of the increase in
productivity during last decades, new conservation techniques have been used by
producers in order to conserve soil. These practices are of great importance in semiarid
countries, as Spain, where erosion is a main problem, specially the one related to water.
In order to study the consequences of the increasing productivity on soil erosion
processes, the present study evaluated the soil losses related to productivity of most
important crops grown in Spain during the last twenty years. The indicators selected
estimated the losses in soils as a function of fruit productivity, tons per year per kg
and economical income of produced item. The productions studied were the most
significant for all the regions of the Spanish territory: tomato, orange, olive, grapes,
wheat, barley, corn, beet, limon, tangerine, melon, grapefruit and sunflower. The
results showed that farmers have improved their productivity at the same time that
soils losses have been decreased from 1987 to 2007 for most of the 52 Spanish
regions. Although some years presented some exception, mainly related to weather
conditions and market tendencies, the trends showed that farmers are producing
more quantity of fruits, cereals and vegetables than twenty years ago decreasing
the erosion processes in all the cases where soil conservation practices have been
applied. |
