Recorventing disturbed lands to its former or productive uses
Landscape reclamation / restoration
Reclamation plan must be made before any disturbing project is undertaken - landscape is a nonrenewable resource !!!
Potential source of pollution (soil erosion, heavy metals, organic pollution, odour etc.)
Aesthetical , economical and ecological reasons
WHY?
![Page 3: Vodohospodářské inženýrství a životní prostředí VIZPstorm.fsv.cvut.cz/data/files/ENEN_11_Reclamation_EIA.pdf · Reclamation plan must be made before any disturbing project](https://reader033.vdocuments.site/reader033/viewer/2022052803/5f22e382ffe33431830c733d/html5/thumbnails/3.jpg)
Most commonly reclamated areas:
mines (quarries, coal mines, spoil tips, pit heaps)
closed landfills (waste ponds, chemical ponds)
contaminated or abandoned areas (brownfields)
Reasons for restoration
natural (fire, flood, earthquake) – usually faster and easier anthropogenic – industry
(every locality can be restored, it is a matter of time and costs)

Reclamation vs Revitalization
Reclamation new use of the land, with no relation to its former state (agriculture, sport areas, buildings)
Revitalization create ecologically valuable areas (increase of landscape stability and biodiversity)
Revitalization should be a part of reclamation!!!
Germany – 15% rec. area (of large surface quarries) must be left to its natural evolution (succession)
Pros and cons of natural evolution:
+ increased biodiversity, low costs, good ecological value
- Long term, lower value for people opposed to a culture landscape

Costs
Technical reclamation/revitalization is expensive (in CZE: mining - app 100000 eur/ha, landfills and brownfields even more
Recultivation reserve (eg. as a fraction from every ton of coal…)
![Page 8: Vodohospodářské inženýrství a životní prostředí VIZPstorm.fsv.cvut.cz/data/files/ENEN_11_Reclamation_EIA.pdf · Reclamation plan must be made before any disturbing project](https://reader033.vdocuments.site/reader033/viewer/2022052803/5f22e382ffe33431830c733d/html5/thumbnails/8.jpg)
Landscape and basic principles
Heterogeneous part of the Earth surface, which consist
of the ecosystems, which are in permanent interaction.
LANDSCAPE:
Landscape → surrounding space, consisting of individual landscape
elements
→ it has both of material and spiritual extension HOME
→ environment of many species (which are effected by)
→ place for anthropogenic activities (mining, production,
construction, …)
![Page 9: Vodohospodářské inženýrství a životní prostředí VIZPstorm.fsv.cvut.cz/data/files/ENEN_11_Reclamation_EIA.pdf · Reclamation plan must be made before any disturbing project](https://reader033.vdocuments.site/reader033/viewer/2022052803/5f22e382ffe33431830c733d/html5/thumbnails/9.jpg)
Landscape ecology:
The science about interactions between organisms and their
environment
1. STRUCTURE: spatial relations between present ecosystems or
landscape units
2. FUNCTION: interaction between spatial units
3. CHANGE: development of the structure and function of
ecological mosaic in time
![Page 10: Vodohospodářské inženýrství a životní prostředí VIZPstorm.fsv.cvut.cz/data/files/ENEN_11_Reclamation_EIA.pdf · Reclamation plan must be made before any disturbing project](https://reader033.vdocuments.site/reader033/viewer/2022052803/5f22e382ffe33431830c733d/html5/thumbnails/10.jpg)
Basic classification of
the landscape
natural (undisturbed by humans – very seldom in Central Europe)
→ The landscape has its „scale“ → Japan x Russian taiga
→ Pyrenees x Himalayas
the scale affects perception of the detail!
cultural (artificial anthropogenic) city
agricultural
industrial
→ „ what can we afford“ (landscape character conservation)

Landscape-generating elements
LP – forests
VP – water (streams, reservoirs, lakes)
TTP – permannent grass
Pa – pastures
Mo – wetlands
Sa – orchards
Vi – wineyards
OP – arable land
AP – anthrop. areas (roads, urbanized places)
Ch – hop fields
landscape structure

Landscape units
linear : line corridors – green fences, roads, railways,
windbreakers, ditches
zone corridors – all corridors, which have their own
environment and typical conditions →
have border effect (ECOTON)! (water
courses)
areal : spots – originates spontaneously or with anthropogenic
contribution

physical stability (biomass is not present – desert, rock,…)
resilience – quick restoration after disturbance
(small amount of biomass)
resistance – resistance to disturbance – (usually high amount of
biomass is present, biodiversity)
Stability???
Ability to resist changes of external conditions
(biotic x abiotic) – climate, pests, ...

Complexity of Environment- Multidisciplinary
- Difficult tasks – experts
- Interconnectivity (cause effect chains)
- Long response times
- Uncertainties
- Difficult to communicate
- Need of a decision supporting TOOL
Environmental Impact Assessment
![Page 17: Vodohospodářské inženýrství a životní prostředí VIZPstorm.fsv.cvut.cz/data/files/ENEN_11_Reclamation_EIA.pdf · Reclamation plan must be made before any disturbing project](https://reader033.vdocuments.site/reader033/viewer/2022052803/5f22e382ffe33431830c733d/html5/thumbnails/17.jpg)
EIA - definition…an evaluation procedure that helps planners and decision-makers to understand the environmental impacts of a proposed project or activity
…a technique for drawing together, in a systematic way, expert qualitative assessment of a project’s environmental effects
1. Planning tool2. Decision making instrument
![Page 18: Vodohospodářské inženýrství a životní prostředí VIZPstorm.fsv.cvut.cz/data/files/ENEN_11_Reclamation_EIA.pdf · Reclamation plan must be made before any disturbing project](https://reader033.vdocuments.site/reader033/viewer/2022052803/5f22e382ffe33431830c733d/html5/thumbnails/18.jpg)
EIA - purpose• Avoiding mistakes that can be expensive and damaging in ecological, social and economic terms • Avoiding conflicts and increasing project acceptance • Integrating short-term needs with long-term goals • Addressing transboundary issues • Improving project design and reducing capital and operating costs• Improving institutional co-ordination • Considering alternative projects and designs • Improving accountability and transparency in planning and decision-making.

EIA - history
- 1970s – USA (from National Environmental Policy Action)
- soon Western countries (70s and 80s)
- Since 1988 in EU legislation
- Today: countries independently modify the exact EIA procedure

EIA - stakeholders
- Developer – private or governmental agency
- Decision maker – government agency
- (+ Advisors)
- Board of experts
- Public
- EIA consultant – performs the study

EIA – process- Differ by country (eg. positive or negative lists)
1. Considering variants of the project
2. Designing the activity
3. Screening (is EIA necessary)
4. Scoping (which topics will be studied)
5. EIA report + review
6. Decision
7. MonitoringMethodology exists

EIA – scopingEnvironmental aspect (ecological & socio-economical)
– Abiotic (land, water, soil, air, etc.)
– Biotic (flora, fauna, biodiversity, ecology)
– Current infrastructure (buildings, roads, monuments…)
– Aestetic, scientific, cultural values
– Interrelationship of the above
