Peat in the mountains of New Guinea

Department of Environment and Conservation

The Department of Environment and Conservation (DEC) was established in 1985. Its mission (approved by the National Executive Council on 22 August 1989) is to ensure natural and physical resources are managed to sustain environmental quality and human well-being.

The key legislations administered by the Department are:

Environmental Planning Act 1978

Environmental Contaminants Act 1978

Conservation Areas Act 1978

National Parks Act 1982

International Trade (Fauna & Flora) Act 1979

Fauna (Protection and Control) Act 1966

Crocodile Trade (Protection) Act 1974

Water Resources Act 1982

It also has an important role under the Forests Act 1992.

The Papua New Guinea Forest Authority (PNGFA) was established in 1993 under the 1991 Forestry Act replacing the former Department of Forest, and unifying all Provincial Forest Divisions and the Forest Industries Council. The PNGFA has 19 provincial offices which include five regional offices. The PNGFA mission statement is to: Promote the management and wise utilization of the forest resources of Papua New Guinea as a renewable asset for the well- being of present and future generations.

PNGFA Group has been created to facilitate sharing of useful data / information that could feed into SOE, MEA and SDG Reports.

Climate Change and Development Authority (CCDA) is a new government entity that is now undergoing transition from the former Office of Climate Change and Development (OCCD). CCDA coordinates the Climate Change efforts of the Government of Papua New Guinea, a continuation of basically where the former OCCD left off. It is the coordinating entity for all climate change related policies and actions in the country. Additionally, it is the designated National Authority under the United Nations Framework Convention on Climate Change (UNFCCC). The office is currently undergoing a transitional phase which requires a major re-structure, in a coordinated and structured manner,complying with its own Climate Change Management Act (CCMA) 2015. The CCMA 2015 clearly defines this in Sections 8-11 of the Act on the organisation’s establishment, purpose, functions and powers.

CCDA is basically tasked with ensuring that Papua New Guinea follows a path of climate-compatible growth; that the country’s economy develops while simultaneously mitigating greenhouse gas emissions and reducing vulnerability to climate change related risks.

Peatlands are common in montane areas above 1,000 m in New Guinea and become extensive above 3,000 m in the subalpine zone. In the montane mires, swamp forests and grass or sedge fens predominate on swampy alley bottoms. These mires may be 4–8 m in depth and up to 30,000 years in age. In Papua New Guinea (PNG) there is about 2,250 km2 of montane peatland, and Papua Province (the Indonesian western half of the island) probably contains much more. Above 3,000 m, peat soils form under blanket bog on slopes as well as on valley floors. Vegetation types include cushion bog, grass bog and sedge fen. Typical peat depths are 0.5‒1 m on slopes, but valley floors and hollows contain up to 10 m of peat. The estimated total extent of mountain peatland is 14,800 km2 with 5,965 km2 in PNG and about 8,800 km2 in Papua Province. The stratigraphy, age structure and vegetation histories of 45 peatland or organic limnic sites above 750 m have been investigated since 1965. These record major vegetation shifts at 28,000, 17,000‒14,000 and 9,000 years ago and a variable history of human disturbance from 14,000 years ago with extensive clearance by the mid-Holocene at some sites. While montane peatlands were important agricultural centres in the Holocene, the introduction of new dryland crops has resulted in the abandonment of some peatlands in the last few centuries. Despite several decades of research, detailed knowledge of the mountain peatlands is poor and this is an obstacle to scientific management.
