Italys Mount Etna erupts on the southern island of Sicily

People watch Italy's Mount Etna, Europe's tallest and most active volcano, spewing lava as it erupts on the southern island of Sicily November 17, 2013. There were no reports of damage or evacuations in the area and the nearby airport of Catania was operating as normal, local media reported. It is the 16th time that Etna has erupted in 2013. The south-eastern crater, formed in 1971, has been the most active in recent years. REUTERS/Antonio Parrinello (ITALY - Tags: ENVIRONMENT SOCIETY TPX IMAGES OF THE DAY)

The valley of Poroma with mesquite trees Prosopis pallida of the Acacias family that survive in arid areas with long taproots that deprive neighbouring plants of water so they die. The trees can replace forest and prevent erosion. At the beginning of the 6th century the Nazca culture in this area collapsed, possibly when these trees were cleared following erosion and desertification after an El Nino event. The trees are now being planted in this region to combat erosion. San Fernando National Reserve, Ica Region, southern Peru
