Food is made up of three major components – proteins, carbohydrates and fats – and each is necessary for growth and healthy living. Although all three provide energy, carbohydrates, which consist of starches and sugars, provide the highest proportion of the food energy (or fuel) that human bodies need to function. Protein, used for building and repairing the body, comes from animal products such as meat, fish, and milk, but also from grains and vegetable foods. Small quantities of fats and oils are also important in a balanced diet.
The history of agriculture in PNG is about 10 000 years old. This history is reviewed here in the context of 50 000 years of human occupation of the Australia – New Guinea region. 1 More is known about what has happened nearer to the present, especially since 1870, than about the distant past. Much of the early history (prehistory) of PNG was unknown until about 50 years ago, but since 1959 there has been a lot of research on the prehistory of PNG, with a major focus on agriculture.
Oil palm prices may hold up in the medium term, with strong demand from India and China. Yet, like other non-oil commodities, oil palm prices are likely to remain volatile, and to experience a long term relative price decline. (Chapter 3). World prices are not the main problem for small farmers in PNG. Three factors are likely to place a ceiling on the economic benefits for small farmers: (i) small farmers remain at the highly competitive end of a large grower market, with little market power, keeping them as ‘price takers’; (ii) a large monopsony (all
Huon Peninsula, Papua New Guinea, is a tectonically unstable, uplifting shoreline ringed by emergent coral terraces.
We have dated corals sampled from the uplifted terraces of Huon Peninsula, Papua New Guinea, that grew during the Marine Isotope Stage 3, to reconstruct sea-levels of the last glacial period from 30 to 55 ka (kiloannum). Mass spectrometric U-series dating methods resulted in high precision dates and could also be used to recognize diagenetically altered samples. The only quantitative test of open-systembehaviour of both uraniumand thorium isotopes involves the comparison of 234U/238U ratios, at the time of coral growth, with present sea-water values.
An analysis of cultural change and generation gaps in the local community of the Nungon ethnic group in the state of Papua New Guinea will be the subject of the study. This ethnic group came into contact with Europeans for the first time in the mid-1930s. The pace of cultural changes within the community has been gradually increasing.
Midway up the slopes of the Andogoro, Moirutapa, and Kundiman mountains that rise up from the surrounding floodplains and separate East Sepik Province from Enga and Western Highlands Provinces in Papua New Guinea, are the traditional settlements of the Upland Arafundi people (Roscoe & Telban 2004:94). Galleries of stencils adorn the walls of caves once used as spirit houses and shelters by the Upland Arafundi people. In the limestone caves they buried their dead, initiated young men, and sheltered from their enemies.
In days gone by some of the Motu-speaking peoples around Port Moresby used to go on annual trading expeditions to the Gulf of Papua. There they would exchange with the inhabitants of that area pots and other valuables for sago and canoe logs. These expeditions were called hiri, and were not only spectacular in terms of the number, nature and size of the sailing craft involved and the cargoes they carried but also very important economically and in other ways to the Motu and others directly or indirectly involved.
For over forty years, archaeologists working along Papua New Guinea’s southern coastline have sought evidence for early ceramics and its relationship with Lapita wares of Island Melanesia. Failing to find any such evidence of pottery more than 2000 BP, and largely based on the excavation of eight early pottery-bearing sites during the late 1960s into the early 1970s, synchronous colonization some 2000 BP along 500km of the south Papuan coastline by post-Lapita ceramic manufacturers has been posited.
How can linguistics contribute to our knowledge about human dispersals in the distant past? We will consider the case of New Guinea and surrounding islands, one of the most linguistically diverse areas of the world. This study is a follow-up on the Eurocores OMLL project Pioneers of Island Melanesia, reported in Dunn et al. (2005).
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 valley 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.
Terra Australis reports the results of archaeological and related research within the region south and east of Asia, though mainly Australia, New Guinea and Island Melanesia - lands that have remained terra australis incognita to generations of prehistorians. Its subject is the settlement of the diverse environments in this isolated quarter of the globe by peoples who have maintained their discrete and traditional ways of life into the recent recorded or remembered past and at times into the observable present .
Two of the unanswered questions of Papua New Guinea prehistory are: (1) whether agriculture was present in the mid-Holocene not only in the highlands but also in the lowlands and Bismarck Archipelago and (2)whether the presence of agriculture might have been influenced by interaction between these regions. This paper addresses these questions through an analysis of prehistoric stone mortars, pestles and figures, which hold information on both style and function.
With 3.8 million cubic meters of tropical wood exported in 2014, primarily to China, Papua New Guinea (PNG) has become the world’s largest exporter of tropical wood, surpassing Malaysia, which had held the top spot for the
past several decades.
Tropical forestry and logging are complex subjects, encompassing a range of diffi cult issues, including land ownership, the sustainability of natural resources, the impact on climate change, the social and economic impact of logging on isolated and relatively untouched, subsistence sector communities, and the protection of the basic rights of the people concerned.
Papua New Guinea’s (PNG) forests and forestry have played an important role in the livelihoods of the people of the country for many years. Forests have provided a source for food, fruits and nuts, building materials, medicinal plants, habitats for refuge and a wealth of other services.
A summary of various datasets on logging concessions, exports, forest cover are presented here.
Papua New Guinea (PNG) has one of the most significant areas of tropical forest in the world. These forests are, however, under threat from commercial logging, clearing of land for agricultural commodities, mining or the expansion of small-scale agriculture to meet the livelihood needs of the country's largely rural population.
The Papua New Guinea Resource Information System (PNGRIS) is a micro-computer-based georeferenced
database containing information on natural resources, population distribution, rural land use, small-holder economic activity and land use potential (Bellamy 1986). It is compiled at 1:500 000 scale for approximately 5000 Resource Mapping Units (RMUs) covering the entire land area of Papua New Guinea (PNG).
PNG has a diverse and rich resource base for plants, animal and aquaculture genetic resources used for food and agriculture. These resources suppor the livelihood of the majority of rural population in the country. The safeguarding, maintainence and sustainable uses of this genetic diversity is essential for the current as well as livelihood security
