DESCRIPTION:A sediment core brought back to Cambridge in 1993 from the sma
 ll infilled lake of Marcacocha located at 3300 m above sea level in Andean
  Peru has provided a 4000-year record that\, even today\, continues to she
 d new light on environmental changes and how humans managed their environm
 ent.  Surrounded by pre-Inca and Inca terraces and ruins\, Marcacocha is l
 ocated next to a major trade route that connects the Inca settlement of Ol
 lantaytambo with the rainforest. By combining the study of conventional pr
 oxies such as pollen\, dung fungal spores\, plant macrofossils and sedimen
 t geochemistry with those that are less orthodox (such as oribatid mites)\
 , we have shown that the record spans the early development of agriculture
  and pastoralism\, the rise and fall of the Inca Empire (c. AD 1400–1533
 ) and into the historic period. Besides providing a detailed palaeoenviron
 mental record\, there are indications that\, particularly from 1000 years 
 ago\, major efforts in agroforestry and landscape stabilisation were being
  practiced. Indeed\, these historic strategies may yet prove important in 
 helping to alleviate the impacts of Peru’s increasingly acute water shor
 tage issues\, as Andean glaciers disappear and ancient aquifers are stress
 ed by unregulated abstraction. This talk presents a welcome opportunity to
  bring the results of the project back to Cambridge after more than two de
 cades.\n
