Rice is a cereal grain, and in its domesticated form is the staple food for over half of the world's human population, particularly in Asia and Africa, due to the vast amount of soil that is able to grow rice. Rice is the seed of the grass species Oryza sativa or, much less commonly, O. glaberrima. Asian rice was domesticated in China some 13,500 to 8,200 years ago, while African rice was domesticated in Africa some 3,000 years ago. Rice has become commonplace in many cultures worldwide; in 2021, 787 million tons were produced, placing it fourth after sugarcane, maize, and wheat. Only some 8% of rice is traded internationally. China, India, and Indonesia are the largest consumers of rice. A substantial amount of the rice produced in developing nations is lost after harvest through factors such as poor transport and storage. Rice yields can be reduced by pests including insects, rodents, and birds, as well as by weeds, and by diseases such as rice blast. Traditional polycultures such as rice-duck farming, and modern integrated pest management seek to control damage from pests in a sustainable way.
Kava or kava kava is a crop of the Pacific Islands. The name kava is from Tongan and Marquesan, meaning 'bitter'; other names for kava include ʻawa (Hawaiʻi), ʻava (Samoa), yaqona or yagona (Fiji), sakau (Pohnpei), seka (Kosrae), and malok or malogu. Kava is consumed for its sedating effects throughout the Pacific Ocean cultures of Polynesia, including Hawaii and Vanuatu, Melanesia, some parts of Micronesia, such as Pohnpei and Kosrae, and the Philippines.
The sweet potato is a dicotyledonous plant that belongs to the bindweed or morning glory family, Convolvulaceae. Its large, starchy, sweet-tasting tuberous roots are used as a root vegetable. The young shoots and leaves are sometimes eaten as greens. Cultivars of the sweet potato have been bred to bear tubers with flesh and skin of various colors. Sweet potato is only distantly related to the common potato, both being in the order Solanales. Although darker sweet potatoes are often referred to as "yams" in parts of North America, the species is even more distant from the true yams, which are monocots in the order Dioscoreales.
Lincoln University is a public university in New Zealand that was formed in 1990 when Lincoln College, Canterbury was made independent of the University of Canterbury. Founded in 1878, it is the oldest agricultural teaching institution in the Southern Hemisphere. It remains the smallest university in New Zealand and one of the eight public universities. The campus is situated on 50 ha of land located about 15 km (9 mi) outside the city of Christchurch, in Lincoln, Canterbury.
Christchurch is the largest city in the South Island and the second-largest city by urban area population in New Zealand, after Auckland. Christchurch lies in the Canterbury Region, near the centre of the east coast of the South Island, east of the Canterbury Plains. It is located near the southern end of Pegasus Bay, and is bounded to the east by the Pacific Ocean and to the south by the Banks Peninsula. The Avon River (Ōtākaro) flows through the centre of the city, with a large urban park along its banks.

In New Zealand, Crown Research Institutes (CRIs) are corporatised Crown entities charged with conducting scientific research.
The Mount Erebus disaster occurred on 28 November 1979 when Air New Zealand Flight 901 (TE901) flew into Mount Erebus on Ross Island, Antarctica, killing all 237 passengers and 20 crew on board. Air New Zealand had been operating scheduled Antarctic sightseeing flights since 1977. This flight was supposed to leave Auckland Airport in the morning and spend a few hours flying over the Antarctic continent, before returning to Auckland in the evening via Christchurch.
Genetically modified crops are plants used in agriculture, the DNA of which has been modified using genetic engineering methods. Plant genomes can be engineered by physical methods or by use of Agrobacterium for the delivery of sequences hosted in T-DNA binary vectors. In most cases, the aim is to introduce a new trait to the plant which does not occur naturally in the species. Examples in food crops include resistance to certain pests, diseases, environmental conditions, reduction of spoilage, resistance to chemical treatments, or improving the nutrient profile of the crop. Examples in non-food crops include production of pharmaceutical agents, biofuels, and other industrially useful goods, as well as for bioremediation.
Yam is the common name for some plant species in the genus Dioscorea that form edible tubers.
HortResearch was a Crown Research Institute of New Zealand. The focus of research in this company was mainly in the development of new fruit varieties and other food products. It was probably most recognised for its plant breeding of various kiwifruit varieties, including new cultivars of Actinidia (genus) chinensis and arguta (species).
Jatropha curcas is a species of flowering plant in the spurge family, Euphorbiaceae, that is native to the American tropics, most likely Mexico and Central America. It is originally native to the tropical areas of the Americas from Mexico to Argentina, and has been spread throughout the world in tropical and subtropical regions around the world, becoming naturalized or invasive in many areas. The specific epithet, "curcas", was first used by Portuguese doc Garcia de Orta more than 400 years ago. Common names in English include physic nut, Barbados nut, poison nut, bubble bush or purging nut. In parts of Africa and areas in Asia such as India it is often known as "castor oil plant" or "hedge castor oil plant", but it is not the same as the usual castor oil plant, Ricinus communis.
AgResearch Ltd is one of New Zealand's largest Crown Research Institutes with over 700 staff and revenue of NZ$160.7 million in the year to June 2014.
In New Zealand, agriculture is the largest sector of the tradable economy. The country exported NZ$46.4 billion worth of agricultural products in the 12 months to June 2019, 79.6% of the country's total exported goods. The agriculture, forestry and fisheries sector directly contributed $12.653 billion of the national GDP in the 12 months to September 2020, and employed 143,000 people, 5.9% of New Zealand's workforce, as of the 2018 census.
Plant & Food Research is a New Zealand Crown Research Institute (CRI). Its purpose is to enhance the value and productivity of New Zealand's horticultural, arable, seafood and food & beverage industries. The interests of the institute are based in horticulture, arable and seafood research, specifically in the areas of sustainable production, bioprotection, elite genetics & intelligent breeding, food and health science and biomaterials.
The management of waste in New Zealand has become more regulated to reduce associated environmental issues. According to OECD data, New Zealand is the third most wasteful country in the OECD.
Megan Cherie Woods is a New Zealand Labour Party politician who served as a Cabinet Minister in the Sixth Labour Government and has served as Member of Parliament for Wigram since 2011.
