Why New Zealand
The concept of kaitiakitanga
Once part of Gondwanaland, New Zealand evolved in isolation for 85 million years before it was discovered by Maori journeying from their homeland Hawaiki around 1000 years ago.
The ethos of kaitiakitanga - guardianship of the land - led Maori to manage New Zealand’s unique environment, putting into practice sustainability restrictions (rahui) that preserved and protected natural resources.
Maori traditionally believe there is a deep kinship between humans and the natural world. People are not superior to the natural order; they are part of it. They believe all life is connected and to understand the world, one must understand the links and relationships within it. Anagenix respects and shares this sense of connection with nature, which is a unique feature of New Zealand’s cultural environment.
New Zealand’s UV advantage
Ultraviolet intensities in the New Zealand summer are extreme on the international UV Index scale – at least 37% higher than similar latitudes in the northern hemisphere. There are three main reasons for this:
- The earth orbits the sun in an ellipse, not a circle. The closest point of approach of the sun to the earth occurs in December/January, which is the southern hemisphere summer. The furthest away is in June/July, which is the northern hemisphere summer. That factor alone means that the southern hemisphere summer will have 7% more UV radiation than the northern hemisphere summer.
- During the summer months, there is a lot less ozone in the southern hemisphere than in the northern hemisphere. Because ozone is generated at the equator, it gets transported to higher latitudes, and that transport is more efficient in the southern hemisphere. This factor adds another 10% UV radiation.
- The remaining 20% is due to the cleaner air in New Zealand.
How does higher UV affect plants?
Ultraviolet causes an accumulation of polyphenols (compounds that absorb the UV and protect the plant). More UV in the sunlight translates to more polyphenols in the plant’s leaves and fruit. Polyphenols have antioxidant properties.
