Description
Summary:Lake Maninjau is a lake formed due to volcanic processes. Located in Agam Regency, West Sumatra Province, the detail of lake genesis remains a debate among experts. The study of paleolimnology to the reconstruction of Lake Maninjau based palynomorph aims to find out how climate change is happening at Lake Maninjau after the formation of the lake as well as how environmental change suck as land use in the area around the lake. Using lake sediment samples, this research will address the specific reconstruction of the lake using pollen as the proxy. Based on the result of the study showed that 150 years ago, Lake Maninjau had a dry climate with climate change become humid 20 years later. Changes from warm to humid climate from 150 years ago can be seen from the growth of vegetation in wetlands, swamps to the mountain rain forest.
