Multi-proxy record of past environmental changes from a tropical peatland (Kyambangunguru, Tanzania)
Résumé
Tropics play a key role in the atmospheric circulation, partly responsible for the variations of climatic conditions,
as they are a major source of heat and water vapour on Earth. Thus, improving our knowledge on past temperature
fluctuations and hydrological regimes in these areas may allow to better constrain the driving forces controlling
climate system. Peatlands are important archives for the reconstruction of past environmental changes because of
their high rates of peat accumulation due to the low rate of plant litter decomposition. The aim of this study was to
reconstruct past environmental changes via the high-resolution analysis of several proxy/climate indicators along
a 4 m peat core collected in SW Tanzania and covering the last 4,000 years (based on 14C dating).
