| Zusammenfassung |
| The growing concern for loss of services once provided by natural ecosystems
is getting increasing attention. However, the accelerating rate of natural
resources destruction calls for rapid and global action. With often very
limited budgets, environmental agencies and NGOs need cost-efficient ways to
quickly convince decision-makers that sound management of natural resources
can help to protect human lives and their welfare. The methodology described
in this paper, is based on geospatial and statistical analysis, involving
simple Geographical Information System (GIS) and remote sensing algorithms.
It is based on free or very low-cost data. It aims to scientifically assess
the potential role of vegetation in mitigating landslides triggered by
earthquakes by normalising for other factors such as slopes and distance
from active fault. The methodology was applied to the 2005 North
Pakistan/India earthquake which generated a large number of victims and
hundreds of landslides. The study shows that if slopes and proximity from
active fault are the main susceptibility factors for post landslides
triggered by earthquakes in this area, the results clearly revealed that
areas covered by denser vegetation suffered less and smaller landslides than
areas with thinner (or devoid of) vegetation cover. Short distance from
roads/trails and rivers also proved to be pertinent factors in increasing
landslides susceptibility. This project is a component of a wider initiative
involving the Global Resource Information Database Europe from the United
Nations Environment Programme, the International Union for Conservation of
Nature, the Institute of Geomatics and Risk Analysis from the University of
Lausanne and the "institut universitaire d'études du
développement" from the University of Geneva. |
