Now, Peru's administration is responding positively to the crisis, although only to further their practical transportation aims, rather than for ethical reasons.
To compound these enviro-political problems, the severe effects of the El Nino weather system have destroyed a great deal of existing transportation infrastructure.
The infrastructure of highways and roads was directly and negatively impacted during the last El Niħo. This network extends for 75,000 km in Peru. A great majority, 50,000 km, are little more than dirt roads and trails. Only a third of Peruvian highways are either gravel or asphalt. Most of the 10,000 km of asphalt roads are in the Pan-American Highway that runs along the coast. Seen as a group, this network is very inadequate because its extension is limited compared to the size of the country.
Additional problems exist for engineers of Peruvian transportation systems in the form of natural disasters. Peru is located in an earthquake-prone area, and has experienced mild volcanic activity, landslides, flooding and tsunamis in past years (www.cia.gov/cia/publications/factbook/geos/pe.html, 2004). As the nation's economy largely depends upon the transportation of marke
