The production of agricultural and horticultural products in New Zealand has impacts on the local environment—soil, water, air, and living organisms.
Over time, these impacts may cause a decline in the level of production. They can also affect ecosystems and communities, causing problems for growers selling New Zealand products in overseas markets.
This assessment activity requires you to research a commercial dairy farmer and write a report that outlines the typical environmental impacts of milk production.

brainstorming ideas may include.
- What is primary production?
- Why is understanding impacts on the environment important?
- New Zealand’s clean green image
- Marketing of New Zealand primary products
- Greenhouse gases
- Tourism
- Sports and recreation
- Water related health issues
- World demand for food safe and sustainable produced products.
- Watch https://m.youtube.com/watch?v=BMnCiOR3UoQ
- Farming activities to be viable and make a profit,
- That the food, fibre and other primary production products are safe to eat and use,
- That food, fibre and other primary production products are of a quality that is acceptable to us – the consumer,
- Food, fibre, and other primary production products are produced, processed and distributed in ways that do not damage the environment,
- That we care for the animals and plants that we farm or grow,
- That farming families and those in the rural community and associated with primary production are able to provide for their social and cultural well-being,The resources of soil, land, air and water are used sustainably and preserved for future generations.
What is an environmental impact?
some environmental impacts.
some environmental impacts.
- Use of high amount of water for irrigation
- Toxic crop sprays must be used, stored and disposed of safely
- Overuse of fertiliser and chemicals could pollute water ways
- Fruit produced must meet acceptable levels of chemical residues and insect controls for overseas markets
- Overuse of heavy machinery can cause soil compaction and damage the soil
- Care must be taken not to pollute the available ground water supply with chemicals
- Pests may develop a resistance to chemicals and require spraying with a higher dose, or a different chemical spray
- The landscape can be affected by the position of buildings and the creation or destruction of native forest or wetland & shelter belts
- Frost protection methods must be used. These could include oil or diesel burning heaters or smoke pots.
- Heavy use of water for irrigation can cause diminishing flow in rivers and affect fish life.
- Unseasonable climatic events like wet weather at harvest time can cause loss of crop or loss of quality in crop.
- High use of energy for cultivation and irrigation.
- Loss of soil by water and wind erosion, and through loss of plant cover
- Use of biological control agents to control weeds.
- Rubbish dumps need to be carefully placed so that they don’t seep into streams and underground water.
- If steep slopes are cultivated valuable topsoil can be washed off by rain.
