Tenerife Module Mission Statement
Universiteit van Amsterdam
Assessing Environmental Vulnerability On the Inner Caldera Slopes and
Llano Basin Areas Within the El Teide National Park by Evaluating
Abiotic and Biotic Parameters Using Field Data, GIS, and Remote Sensing.
Goal: Enhance master’s students’ knowledge and experience in
‘Natural Resource Management and Sustainability’ by applying
theoretical knowledge of Physical Geography and the related
disciplines of Ecology, Environmental Sciences, and Human
Geography to environmental problems encountered in the field.
Central Course Theme: Assessment of the Vulnerability of selected
geo-ecosystems on the island of Tenerife, integrating the master’s
students’ knowledge to foster sustainable management practices of
natural resources.

Research Proposal
Universiteit van Amsterdam
Evaluate Environmental Risks: Natural & Manmade
Tools: Field Authenticated GIS & Remote Sensing
Goal: Evaluation of Environmental Hazards
Selected Study Area: Inner Caldera Slopes, Llanos within the caldera
of the Teide-Pico Viejo Complex Volcano
Research Question: Can these analysis be successful and applicable to
the larger scale ecosystem mosaics?

Assessing Environmental Vulnerability On the Inner Caldera Slopes and
Llano Basin Areas Within the El Teide National Park by Evaluating
Abiotic and Biotic Parameters Using Field Data, GIS, and Remote Sensing.
Climate: Northwesterly trade-winds bring rain to north, rain
shadow to the south. Llano High Mountain Scrub.
Geology & Hydrology: Miocene subsequent serial volcanic
eruptions & flows; massive slides create layered topography and
perched aquifers. Study Area dominated by Canadas Edifice.
Soils: Volcanic island of variable relief, varied climate. Older
Oxisols, Andisols to lithic Inceptisols. “Buried soils”. Llano
Arenosols (lithic fluvents).

Analysis: Landslide Hazards Scoring Variables
Total Score = (Rise/Run Score - Roughness Score- Vegetation Score -
Shoulder or Dike Score + Cliffs Score + Boulders Score + Sinuosity
Score)
•Rise/Run scores scale of 1 to 3.
•Roughness Score, scale of 0 to 3.
•Vegetation Score, scale 0 to 3.
•Cliff Scores ran from 0 to 2.
•Boulder Scores ranged from 0 to 2.
•Sinuosity Scores ranged from 1 to 3 and were determined by dividing
length of the estimated slide length, in meters, by the area of the slides
runout, in square meters, and then multiplied by 100.
