Our Land and Water

Our Land and Water is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Our Land and Water rather than just read about it. In short: Our Land and Water (Māori: Toitū te Whenua, Toiora te Wai) was one of New Zealand's eleven collaborative research programmes known as National Science Challenges. Running from 2016 to 2024, the focus of Our Land and Water (OLW) research was enhancing the productivity of New Zealand farms while improving the quality of land and water.

Key takeaways

  • Our Land and Water belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Our Land and Water to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Our Land and Water from memory before moving on to harder problems.

Reference excerpt

Our Land and Water (Māori: Toitū te Whenua, Toiora te Wai) was one of New Zealand's eleven collaborative research programmes known as National Science Challenges. Running from 2016 to 2024, the focus of Our Land and Water (OLW) research was enhancing the productivity of New Zealand farms while improving the quality of land and water.

Establishment and governance The New Zealand Government agreed in August 2012 to fund National Science Challenges: large multi-year collaborative research programmes that would address critical issues in New Zealand's future. The funding criteria were set out in January 2014, with proposals assessed by a Science Board within the Ministry of Business, Innovation, and Employment (MBIE). After a planning phase in 2014, MBIE approved the Crown Research Institute AgResearch as the host institution. OLW was formally launched on 26 January 2016 by the Minister for Science and Innovation Steven Joyce; its inaugural director was Ken Taylor, and Chief Scientist was Richard McDowell. The Māori name of Our Land and Water, Toitū te Whenua (let the land's permanence remain intact) Toiora te Wai (let water abound), was an adaptation of the whakataukī (proverb) "Toitū te whenua, whatungarongaro te tangata" (land is permanent, while people come and go). OLW was hosted by AgResearch, with twelve other New Zealand research partners including the six other Crown Research Institutes (GNS Science, Scion, ESR, Landcare Research, NIWA, and Plant & Food Research), Lincoln Agritech, and four universities: the University of Auckland, Massey University, Lincoln University, and the University of Waikato. It was the largest of the Science Challenges at launch, with an initial budget of $96.9 million over 8 years, though it was second in funding to the Science for Technological Innovation Challenge with its $106 million budget.

In December 2015, after feedback from MBIE's Science Board, the OLW Directorate sought advice from Ray Collins at the University of Queensland on incorporating value chain management into the proposed research programme. At the time of receiving its second tranche of funding in November 2018, the Challenge had 31 research projects completed or in progress, and had produced 43 journal articles. By mid-2019, OLW was partnered with 16 research organisations, and was coordinating the work of around 160 scientists and 100 collaborating organisations. In March 2020, Ken Taylor retired and Jenny Webster-Brown was appointed director of OLW. The OLW Challenge formally ended in June 2024.

Research OLW's research focus was on three connected areas: Future Landscapes, encouraging a diverse 'mosaic' of land use that is both more resilient and has better soil and water quality; Incentives for Change, making higher-value exports that reward sustainable practices; and Pathways to Transition, speeding up the ability of farmers and growers to adopt new research and technology.

Worked examples

Example 1 — a first encounter with Our Land and Water

Start with the simplest possible case. Write down what Our Land and Water claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Our Land and Water before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Our Land and Water ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Our Land and Water

In research
Our Land and Water appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Our Land and Water in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Our Land and Water is common in secondary-school and first-year university syllabi. It links to neighbouring topics Agricultural research, National Science Challenges, so understanding it makes those chapters shorter.
In everyday life
Look for Our Land and Water outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
