Genesis and development of an interfluvial peatland in the central Congo Basin since the Late Pleistocene
2023, Quaternary Science ReviewsA focus on the last 1000 years of natural environmental changes in the tropical rainforests of West and Central Africa. Can we detect anthropogenic disturbances?
2023, Global and Planetary ChangeCitation Excerpt :For the past millennium, the palaeoecological data only show minor variation in the Guineo–Congolian rainforest cover, suggesting that global-scale climatic variability (Bradley, 2000; Broecker, 2001) had little major impact. As a result, the vegetation fluctuations inferred from pollen records during this period have been generally attributed to human activities regardless of being able to demonstrate a cause and effect link (Elenga, 1992, Elenga et al., 1994, 1996; Reynaud-Farrera et al., 1996; Vincens et al., 1998). If one wants to understand and potentially disentangle the respective impacts of human disturbance and climate change in the evolution of the West and Central African rainforests with a focus on the scale of the last millennium, the approach used here will be a priori different because on the one hand the environmental modifications are less contrasted than around 2500 yr BP and, on the other hand, the increasing sedentarization of human populations in the forest or on its margins must be taken more into consideration.
Tropical peatlands in the anthropocene: Lessons from the past
2022, AnthropoceneUnderstanding the 2500 yr BP rainforest crisis in West and Central Africa in the framework of the Late Holocene: Pluridisciplinary analysis and multi-archive reconstruction
2020, Global and Planetary ChangeCitation Excerpt :Finally, after ca. 1000 cal yr BP, a large increase in rainforest diversity is observed, linked to the progressive spread of numerous more mature trees belonging to the present day forest habitat (Alstonia congensis, Gaertnera paniculata and Lophira alata), and accompanied by the continuous colonization of pioneer trees. Near the right bank of the Congo River, in the southern part of the Batéké Plateau, two cores were recovered from peats deposited in Ngamakala pond (400 m asl) (Elenga, 1992; Elenga et al., 1994). The pollen data from the first core show that hydromorphous forest developed between 10,880 yr BP (185 cm depth) up to ca. 3950 yr BP (170 cm), characterized by an abundance of Syzygium and Sapotaceae taxa.
