INTENSIVE AGRICULTURE OF PEAT LAND AREAS TO REDUCE CARBON EMISSION AND FIRE PREVENTION ( A Case Study In Tanjung Jabung Timur Tidal Lowland Reclamation Jambi)

The peat swamp reclamation was done by drainage process that possible to get serious environmental impacts on peat land ecosystems. This drainage process often affects to the environmental degradation that increase carbon emissions. The key to the success of agricultural cultivation in peat lands is how farmers are able to control water table in the root zone. The depth of water table is ideal for food crops in zones of 20-30 cm below the soil surface. The study aims to determine the effect of water table control to the reduction of carbon emissions and to increase the potential for cropping intensity. The study was conducted in the Delta Berbak reclaimed tidal areas of Tanjung Jabung Timur Jambi Province Indonesia. Data collection was conducted from May to October 2012. Control of water table in tertiary block was done by tertiary gate operation. Results showed that water table was rise from an average of -46.53 cm to -22.7 cm below the soil surface. This means that the control of water table by the tertiary gate operations are able to make the land can be potentially cultivated of food crops and can reduce CO2 emissions of 41.7 tones / ha / year to 20.5 tones CO2 / ha / year that is able to reduce 50% of the total emissions carbon. Under tertiary gate operation the Water table depth can be maintained at 20-30 cm below soil surface so that the soil surface still moisture and could prevent fire hazard.
