  1. Quantitative Assessment of Vegetation Renaturation and Soil Degradation along Corridor of Petroleum/Gas Pipelines and Shirvan National Park, Azerbaijan EMIL BAYRAMOV, PhD, CGEO Postdoctoral researcher Institute of Cartography Dresden University of Technology, Germany Email: emil.bayramov@yahoo.com

  2. LOCATION AND CHARACTERISTICS OF BTC AND SCP PIPELINE ROUTES BTC/SCP Oil Pipeline Construction completed: 2005 BTC and SCP Distance in Azerbaijan: 443 km BTC Export Capacity: 1 million barrels of oil a day BTC and SCP Distance in Georgia: 248 km SCP Export Capacity: 8 billion cubic metres of gas per year BTC Distance in Turkey: 1076 km BTC and SCP Diameter: 42” Total BTC Distance: 1768km BTC and SCP Depth: 1-30 m Total SCP Length: 691 km

  3. CONSTRUCTION PRINCIPLES OF BAKU-TBILISI-CEYHAN (BTC) AND SOUTH CAUCASUS PIPELINES (SCP)

  4. DETERMINATION OF VEGETATION PEAK SEASON Total number of IKONOS satellite images: 21

  5. ACQUISITION OF IKONOS SATTELITE IMAGES AND PLANNING OF VC PERCENTAGE ESTIMATION • Total number of IKONOS satellite images: 21 • Year of imagery acquisition: 2007

  6. REGRESSION ANALYSIS BETWEEN NDVI AND IN-SITU ESTIMATED VC - Estimations were taken along 60 m long transects placed across On-RoW. - VC percentage involved the use of quadrate with the size of 1m x 1m and (minimum sampling 8 quadrates per transect for On-RoW and 3 for Off-RoW. Relative proportion of bare ground to vegetation that can be observed looking vertically onto the quadrate.

  7. RESULTS FOR REVEGETATION PROGRESS ASSESMENT

  8. QUANTIFICATION OF VEGETATION COVER PERCETAGE AND RESTORATION PROGRESS The findings show that 8.9 million sq. m. of territory out of 19.6 million sq. m. was restored and 10.7 million sq. m. of territory still requires restoration to comply with environmental acceptance criteria.

  9. SHIRVAN NATIONAL PARK (SECOND STUDY AREAS) Area: 652 sq. km.

  10. DETERMINATION OF VEGETATION COVER PEAK IN THE SHIRVAN NATIONAL PARK

  11. RESULTS (Vegetation Cover Changes) (c) (d) (b) (a) 01.06.2007 21.05.2000 24.05.2010 21.05.2009 (e) (f) The modeling of NDVI for the Shirvan National Park revealed that the area of bare lands decreased from 2000 till 2010

  12. RESULTS (USLE spatial factors) (a) Rainfall Erosivity (R) Input Data: Rainfall (Worldclim Database) ; Recommended Rainfall intensity value by Hudson (1995) and (Wischmeier & Smith 1978) (b) Soil Erodibility (K) Input Data: The recommended soil erodibility factor (K) recommended by Morgan (2005) assigned to the map of soil texture types developed by Schmidt (2005) (c) Vegetative cover factor (C) Input Data: Landsat-5(TM) NDVI for 2010 (d) Topographic Factor (LS) Input Data: DEM from 1:25000 topographic maps with spatial resolution of 5 meter Erosion-control Practice Factor (P) Since no erosion-control measures were taken in SNP, erosion-control practice factor was assigned to 1

  13. RESULTS (Predicted Erosion Prone Areas using USLE) Soil Loss > 10ton/ha = 38.92 sq. km. (USLE with C-factor) Soil Loss > 10ton/ha = 7.8 sq. km. (USLE with C-factor)

  14. 1. Areas of bare lands were decreasing for both the corridor of oil and gas pipelines and Shirvan National Park. That is a positive spatiotemporal environmental trend related to a number of strategic restoration measures.  2. GIS and Remote Sensing based approach can significantly support in the monitoring of environmental restoration activities and quantify how efficient is the investment into the restoration processes 3. Oil pollution is still significant in the Caspian Sea and the quantitative monitoring activities can contribute to the cleaning activities CONCLUSSIONS
