M. About 15% of the territory of Andalucia suffers "serious erosion".

Some 15 percent of the more than 87,260 km squares covering the territory of Andalucia suffering from "serious" of erosion, one of the most widespread environmental hazards of the region that impoverishes the soil causing the degradation of natural ecosystems and the reduction from productive potential of agricultural areas.

Thus, as is clear from the Environment Report for 2009 Andalucia consulted by Europa Press, specifically, 14.8 percent, ffxiv gil, of the Andalusian region have lost ground "high and very high", of which 10 percent are in agricultural areas and 5 percent in areas of natural vegetation.

On the other hand, 64.3 percent of the region is subjected to low soil losses, introducing the remaining 20.9 percent a moderate soil losses.

This problematic, conditioned Mainly by factors such as precipitation,, sto energy credits, the transformation of plant coverage, usually due to human actions, not sufficiently studied, as supported by the Environment in the report, which acknowledges that it would be necessary to launch a network of assessment and monitoring of soils similar to those applied to areas such as water, air, meteorology, etc.

By provinces, are the East which, sto energy credits, have the highest levels of soil losses. Thus, they reach in Malaga, Jaen, Granada and Almeria percentages of 32.5 percent, 21.7 percent, 17.4 percent and 15 percent respectively of its surface.

Along with these provinces Cadiz is a 18.2 per cent of its area affected. In addition, the Environment stresses the coincidence of this distribution in Almeria and Cadiz, for while the former is in this group of provinces with high levels of erosion by combining low plant cover and low rainfall, Cadiz is included just the opposite, ie but has a high vegetation cover also recorded the highest levels of rainfall erosivity.

At the other extreme, are located in the provinces of Huelva, Seville and Cordoba with only 3.1 percent, 7 percent and 9.7 percent of the respective areas affected by high and very high losses.

For these cases, the greatest loss would be located either in agricultural landscapes and / or natural, depending largely on the density of natural vegetation and the various agricultural uses. 70%

Of losses in agricultural areas

The areas of high soil losses are at a 68.4 percent on agricultural areas, the olive, the herbaceous and woody rainfed upland of the main ways in which they occur, resulting in highly significant that at the regional level 53 , 4 percent of woody crops in dry land, 31.9 percent of the olive and 26.9 percent of irrigated arable crops are under severe soil losses, reaching for the whole agricultural landscapes the region by 20.7 percent.

On the other hand, it is possible to group the different provinces of Andalusia on the basis of the great landscapes that produce the highest soil losses. In Almeria are concentrated in the areas of natural vegetation. In Cordoba, Jaen, Sevilla and to a lesser extent, Granada and Malaga, are concentrated in agricultural landscapes, and finally, the Cadiz and Huelvadistributed both in agricultural areas and in those of natural vegetation.

Almeria is the province with the greatest losses of soil, 71 percent, natural vegetation on land. The remaining 29% of the areas of heavy losses on agricultural areas is being woody and herbaceous crops in dry land training mainly present in these areas.

For its part, Cadiz and Huelva maintained a similar proportion as the distribution of areas with heavy soil losses: 54.3 and 56.5 percent respectively on agricultural areas and 45.6 and 43.3 percent on natural forest areas.

Within this similarity, whether any differences in terms of agricultural and natural typologies that support the most eroded areas. While in Cadiz are rainfed herbaceous crops in Huelva are these and olives.

With regard to areas of natural vegetation in Huelva the largest losses occurring in grasslands and areas of low vegetation, while in Cadiz are these and scrub woodland, probably because the latter found on steep slopes, although presumably one greater protection of the soil.

Cordoba, Jaen and Seville concentrated areas with heavy soil losses on agricultural areas with dedication found on these 89.6 percent, 80.5 percent and 74.8 percent, respectively, of the affected areas. Stresses that, while in Cordoba and Jaen are concentrated in areas of olive groves, in Seville are mainly on rain-fed arable crops.

Granada and Malaga have a similar structure in the distribution of areas with heavy soil losses, locate these mainly agricultural land, 66.4 and 64 percent respectively-affected areas, but also do so significantly over areas natural (33.5 and 35.9 percent respectively).

In both provinces, are woody crops in rainfed crops in rainfed and olives applications where the greatest losses occur with a similar distribution among the three in Granada and a little more inclined towards the woody and herbaceous upland province Malaga.

As for their distribution in areas of natural vegetation, this is concentrated in areas of low vegetation in Granada and is distributed more or less regularly in the various natural landscapes in Malaga.
