Large-scale subclimax in the Amazonian lowland forests due to pre-Colombian deforestation

  • Head of research Risto Kalliola
  • Language n/a

Hundreds of geoglyphs, geometrically formed man-made earth works, have only recently been found in southwestern Brazilian Amazonia and adjacent Bolivia. Geoglyphs occur in an area that partly overlaps with bamboo-dominated forests that are exceptional rain forests because they are dominated by a single species. The aim of the project is to find out if there is a causal relationship between bamboo forests and geoglyphs.

Converged Infrastructure for Emerging Regions (CIER)

  • Head of research Pertti Raatikainen
  • Language n/a

Converged Infrastructure for Emerging Regions (CIER) will design and implement the prototype of a self-configuring, cost- and energy effective, multi-radio, wireless backhaul network suitable for providing broadband connectivity to rural areas throughout the world, which are experiencing limited or none connectivity to the internet. Our vision is that communication infrastructure in emerging regions (Africa and parts of Europe) will be based on heterogeneous wireless mesh networks to connect geographically very large areas in an extremely harsh environment.
