The agricultural, forestry, and fishing sector accounts for most of the labour force of PNG. Agriculture currently accounts for 25% of GDP and supports more than 80% of the population. Most agriculture is subsistence, while cash crops are exported. The main crops by value are
coffee,
oil,
cocoa,
copra,
tea,
rubber, and
sugar.
Agriculture Agriculture in the country includes crops grown for domestic sale and international export, as well as for
subsistence agriculture. Nearly 40% of the population are subsistence farmers, living relatively independently of the cash economy. Their traditional social groupings are explicitly acknowledged by the
Papua New Guinea Constitution, which expresses the wish for "traditional villages and communities to remain as viable units of Papua New Guinean society" and protects their continuing importance to local and national community life. This makes farming the most widespread economic activity. Most is carried out through simple rainfed
surface irrigation, with specific techniques varying by location.
Taro is a historical crop, although the introduction of the now-staple
sweet potato allowed for cultivation as high as .
Metroxylon (a
sago palm) is another common crop. It is estimated that only 30% of the country's land has climate conditions and terrain amenable to agriculture. Most produce comes from
smallholders, who farm less than . Plantation production has decreased since the 1980s, and by the mid-2010s smallholders produced 70% of tree crops.
Intensive farming is carried out in highly populated areas, with a variety of land management techniques used to maintain soil productivity. Other crops produced and consumed domestically include sweet potato, banana, sago, taro, cassava, and sugarcane.
Timber The timber industry was not active in 1998, due to low world prices, but rebounded in 1999. About 40% of the country is covered with timber rich trees, and a domestic woodworking industry has been slow to develop. As of 2018, over three-quarters of the forest was considered
old-growth, 11.9% was heavily logged, and 0.2% had been logged at small-scales.
Fish Fish exports are confined primarily to shrimp, although fishing boats of other nations catch tuna in Papua New Guinea waters under license. The country has inland fisheries and
aquaculture. Marine resources include
sea cucumber, shrimp, and tuna. There is a domestic shrimp fishing industry, and a tuna
longline fishing industry. Deep-water tuna fishing and
purse seine fishing is carried out in Papua New Guinea waters by foreign ships. The overall market is thought to be somewhere between K350 and K400 million per year, although this is highly variable. ==Industry==
