IAMSLIC 31st Annual Conference

October 10th-14th, 2005

Rome, Italy

a case study on using spatial collections

and remote sensing to protect

aquatic resources

IAMSLIC Rome 2005


Project summary

Project Summary

  • In 1997 the Nature Conservation Sector (NCS) of the Egyptian Environmental Affairs Agency (EEAA), through the Egyptian Environmental Policy Program (EEPP) assisted by the United States Agency for International Development (USAID), formed the Red Sea Rangers.

  • A seminar funded by USAID trained Rangers to use spatial collections and remote sensing to map and help manage Red Sea coastal resources

  • Techniques used image processing and GIS software to integrate satellite images, ancillary GIS data, and Red Sea field observations

  • A summary of the training and challenges of communicating technical issues in a multi-cultural environment are presented

The red sea egyptian coastline

The Red Sea: Egyptian Coastline

  • 1500 km Coastline

  • One of the World’s most spectacular recreational diving destinations

  • Extremely popular tourist location

  • A major Mid-East shipping route

  • Tremendous growth potential

Marine resources impacts

Marine Resources Impacts

IAMSLIC Rome 2005


Potential impacts

Damage to coral reefs from marine recreation (boating, fishing, diving, and collecting)

Over-fishing

Aquatic and terrestrial habitat degradation

Commercial shipping accidents

Development increases need for Land-based solid waste disposal sites

Potential Impacts
