Recovery of degraded areasDegraded Area Recovery Plan
different levels of degradation to levels similar to those found at the moment
prior to human intervention. Human activities, whether for food production
or extraction of raw material for industry, has been changing the nature and environment in which live. For this reason and due to the growing concern with the environment, it is imminent the need for recovery, which can then be drawn up in a Recovery Plan of Degraded Areas.
Depending on the level of damage to the ecosystem, for often not only the vegetation is affected, but also its ability to replenish Natural. For this reason, as in any process, the rehabilitation of the area needs a initial assessment of the situation.
Basic Concerts
DEGRADED AREAS ARE GENERATED BY SIGNIFICANT INTERVENTIONS IN PHYSICAL PROCESSES.
ENVIRONMENTAL DEGRADATION = NEGATIVE ENVIRONMENTAL IMPACT.
Degradations
Set of processes resulting from damage to the environment, by which some of its properties are lost or reduced, such as the quality or productive capacity of environmental resources.
Soil Degradation
Adverse changes in soil characteristics in relation to its various possible uses, both established in planning and potential.
Restoration
Reproduction of the exact conditions of the site, as they were before being changed by the intervention.
Recovery
The altered location is worked in such a way that the environmental conditions end up being close to the conditions prior to the intervention; that is, it is a question of returning the balance and stability of the active processes to the place.
Reabilitation
Altered place destined to a given form of land use, according to a previous project and in conditions compatible with the surrounding occupation, that is, it is about reusing the area for another purpose.
Remediation
Actions and technologies that aim to eliminate, neutralize or transform contaminants present in the subsurface (soil and groundwater). Refers to contaminated areas.
What is a Degraded Area Recovery Plan?
A disturbed or degraded area is defined by the occurrence of change in biotic and abiotic environmental properties due to the impacts of an activity.
This allowed the workers to be involved in the job instead of feeling like they had been made redundant by technology.
Basic recovery procedures and measures
Type Of Degraded Area | Main Degradation Processes | Some Corrective Measures |
Abandoned Mining in Urban Regions | · Runoff of surface water; · Erosion by grooves and ravines; · Slips; · Deposition of sediment and particles. | · Revegetation; · Surface water collection and conduction; · Slope and block stabilization. |
Industrial and Urban Waste Deposit | · Physical-chemical interactions in the soil (soil pollution); · Runoff of surface water; · Movement of subsurface waters. | · Deposit prospecting; · Total or partial removal, transport and disposal of waste; · “In situ” soil treatment; · Soil decontamination or remediation. |
Urban or Rural Boreholes | · Erosion by mouths; · Movement of subsurface waters. | · Control of use and occupation; · Surface water collection and conduction; · Drainage of subsurface / bottom waters; · Stabilization of the slopes of the nozzle or grounding. |
Housing Occupation of Slopes in Situations of Risk | · Slips; · Runoff of surface water. | · Surface water collection and conduction; · Slope stabilization (with or without containment structures); · Revegetation. |
Irrigated Agricultural Occupation | · Densification and compaction of the soil; · Acidification of the soil by leaching. | · Irrigation control; · Irrigation control; · Correction of soil acidity. |
Silted Courses and Bodies | · Deposition of sediments and particles; · Floods and floods. | · Erosion control upstream; · Dredging of sediments; · Hydraulic works. |
