But scientists in Indonesia have added a third category of 'mid-level entrepreneurs'. These entrepreneurs buy unregulated access to land for oil palm and clear it by burning, seemingly unrestrained by government.
Scientists at the World Agroforestry Centre, who have been studying land conversion in Sumatra, say they have identified this third group of local land investors who operate outside the government system, making them potentially more difficult to regulate.
These people acquire land under informal rules at village level, effectively sidestepping the Government land-use system. They bring in their own labour to clear the land for oil palm, regardless of the land's formal government status and in the absence of any permits to do so.
Policies and policing need to be adjusted to deal with the newly identified group if the annual fires and subsequent haze are to be reduced. Holding plantation companies accountable for the fires within their boundaries would help reduce the problem but not extinguish it.
About half of the fire 'hot spots' in Riau province are on land with legal permits for large-scale operations (industrial timber, oil palm and logging). The rest occur as part of illegal activities, in areas which have been slated for conservation or non-production.
These hot spots are mostly concentrated in three districts within Riau province. Some neighbouring districts with similar conditions have so far avoided the problem this year, which suggests that lessons might be learnt about governance.
The fire-haze episode straddling the Strait of Malacca in June 2013 has reignited a decades-long debate about responsibility. In the current debate, finger pointing still alternates between the small- and large-scale agricultural operators. The latter include companies with headquarters in Singapore and Malaysia, where the undesirable haze accompanies the financial returns on their investments.
Before 1998, the blame for starting the fires was put exclusively on smallholders' 'shifting cultivation' techniques, with large-scale plantations and development projects protected from any criticism by the government.
But the 1997/8 fires in Sumatra and the change of regime in Indonesia threw new light onto the debate and it became evident that burning was the cheapest option widely used by all farmers, whether on a small or large scale or on peat or mineral soils.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
