SUMMARY

Tropical peat swamp forests in Southeast Asia had been considered to be one of the most important parts of largerecosystems due to the huge amount of carbon stock. Yet, recent rapid and intensive deforestation to procure timber and land preparation for commercial plants or crops (oil palm or Acacia plantations) have induced fundamental changes in the material cycling. Especially, frequent peat fires occur in every dry period especially in Indonesia, which changes the environment fundamentally and emit huge amount of greenhouse gases. We focused on the effects of human impacts on groundwater chemistry in the degraded peatland area in East part of Sumatra Island and Central Kalimantan, Indonesia by comparing with the observation in intact peat swamp forest and secondary forest…
