Soil loss - Coggle Diagram
Soil loss
¿What is?
It is a degenerative process that reduces the current or future capacity of soils
Types of soil degradation
Erosion.
Soil erosion is a discontinuous and slow phenomenon that consists of the mobilization of landslides from the surface and that, in the long term, generates changes in the appearance of the land.
Compaction.
destroys the structure and collapses or diminishes the pores, which limits the space
for the storage or movement of air and water in the soil
Artificialization.
occupation of land for the creation of housing, infrastructure and equipment.
Acidification.
is the increase in the concentration of H+ ions in the soil.
Pollution.
The concentration of these contaminants in the soil above certain levels entails a large number of negative consequences for the food chain and as a consequence for human health as well as for all types of ecosystems and other natural resources.
¿How and how much does soil degradation influence our lives?
Soil degradation already affects a quarter of the world's population. Erosion grows and affects 20% of agricultural land, 15% of grasslands and 30% of forests.
1.5 billion people depend on these soils to survive. Erosion brings with it hunger, migration and damage to the ecosystem.
solutions for the sustainable management of soil loss
Develop capacities and strengthen extension on soils
Stop soil degradation
Restore and rehabilitate degraded soils
Implement land use planning
Treat wastewater
Properly dispose of waste
reduce erosion
Causes of deterioration
soil acidification due to intensive industrialization and the burning of fossil fuels
bad tillage practices
Soil compaction by heavy machinery
Deforestation leading to soil erosion
intensification of agriculture
