The big scale sawah rice field "Mega Rice Project. ' was inifiated in 1995 by Presidential Decree No. 82. (Development of One Million Hectares of Peatland for Food Crop Production in the Province of Central Kalimantan, Peat reclamation). The settlement of 350,000 families into this area was planned by the Ministry of Transmigration. Until today, approx. 13,000 families in the Dadahup-Larnunti region were settled, facing hard conditions on clear-felled areas. Over 4000km of channels were built with high time pressure from Spring 1996 to 1998 (compare satellite images from these period) using US$ 225 million from the Indonesian reforestation fund. The winners were forest industry and canal construction companies. After the Indonesian economic crisis of 1997/1998 the financial situation became worse. During this lime frame, between autumn 1997 and spring 1998, draught and heavy fires mewed as well.

A multispectral and multitemporal image analysis has been used to monitor the environmental importance and agricultural potential as well as wildlife conservation aspects. This report gives information's about field trails to Central Kalimantan in March 1997 and in June and Nov. 1998. The natural vegetation of most tropical peatland is rain forest containing trees of commercial value, e.g. Ramin. Selective forestry is probably the most sustainable use of this resource, but it is also the principal loser when more destructive developments take place. The current status of forestry on tropical peatland ...

The magnified section shows part of the Central Kalimantan province that was allocated for the Mega Rice Project. The project was divided into five work stages: block A, B, C, D and E. P indicates the remaining pristine peat swamp forest area. Abstract The overall aim of this research programme (began in 1995) is to investigate the evolution and the economic potential of the peat swamp forest (PS.F.) resource El Central Kalimantan by remote sensing techniques. A multispectral and multitemporal image analysis was used to monitor the environmental importance and agricultural potential as well as wildlife conservation aspects.

Peat Swamp Forests (PSF) are among the earth's most endangered and least known ecosystems. They have a huge carbon storage capacity but are extremely fragile and liable to disturbance. Local communities have used them extensively for centuries without significant impact on the environment. This changed in 1995 when a programme of massive peatland conversion, the so-called Mega Rice Project (MRP), was initiated with the aim of converting one million hectares of peatland, in Central Kalimantan, Indonesia, into rice fields. Between 1996 and 1998 more than 4000 km of drainage and irrigation channels were constructed in the designated area. Boosted by the El Nino Southern Oscillation (ENSO) episode in 1997, many fires initiated for land clearance purposes spread into pristine forest areas where they continued to ...

More than 200 000 km were burned from 14 March to 8 August 2003, of which 71.4% was forest, 9.5% humid grassland, and 2.15% bogs or marshes. During 1996 to 2003, 32.2% of the forested area and 23.36% of the total area was burned, and 13.9% of the total area was affected by fire at least twice. Direct carbon emission from this 2003 fire was around 400640 Tg. The 2003 Siberian fires could well have contributed to the high increase of the atmospheric CO2 and CO concentration in 2003. The increasing human pressure coupled with intensive fire severity, recurrent fire frequency, and increasing occurrence of summer droughts will reduce the carbon sequestration potential of this important carbon pool.

In this Letter, three ENVISAT instruments were used to investigate the extent and impact of the forest and peatland fires that devastated large areas in Central Kalimantan, Indonesia in 2002. Reduced spatial resolution MERIS imagery was used to identify simple land cover features and smoke plumes.

A strong El Niño-Southern Oscillation (ENSO) led to drought in many parts of Indonesia, resulting in elevated fire occurrence comparable with the previous catastrophic event in 1997/98. Synthetic Aperture Radar (SAR) data promise to provide improved detection of land use and land cover changes in the tropics as compared to methodologies dependent upon cloud and haze free images. This study presents the first spatially explicit estimates of burned area across Sumatra, Kalimantan and West Papua based on high resolution Sentinel-1A SAR imagery. Here we show that 4,604,569 hectares (ha) were burned during the 2015 fire season (overall accuracy 84 %), and compare this with other existing operational burned area products (MCD64, GFED4.0, GFED4.1s). Intersection of burned area wi...
