New Zealand doesn’t export milk and beef, or even grass. It exports water. This is how Tim Groser sees NZ’s agricultural relationship with the world. A country well-off in terms of water is well-prepared to feed a swelling global population. Tim Grosner wears many hats, but they are all connected: Minster of Trade, Minister of Conservation, Associate Minister of Foreign … Read More

A Dutch research team has analysed the effect of agricultural trade liberalisation on global greenhouse gas emissions. Their study finds that a full liberalisation of agricultural trade (ie, removal of all trade barriers, quota and subsidies globally) would result in a 6% increase in global greenhouse gas emissions in 2015.

We have an addiction problem. The craving for P goes right down to our bones and DNA. I’m not talking about methamphetamines, but phosphorus. We are about 1% phosphorus, by weight. Written as ‘P’ in chemical shorthand, it is an essential building block for proteins and bones, and central to our internal energy production. While … Read More

New Zealand’s farming leadership have not distinguished themselves in the debate about climate policy. Federated Farmers president Don Nicholson has called for NZ to set no target for emissions reductions and for agriculture to be excluded from the emissions trading scheme, and former vice-president Frank Brenmuhl is still ruminating on the need for more debate [...] … Read More
