Editor's note

Kia ora koutou katoa and welcome to your New Zealand newsletter.

This week, Matthew Hall, at Victoria University of Wellington, explores our relationship with the living world and why it seems so hard for us to take steps to redress the decline of biological diversity. He writes that our view of plants and animals as natural resources is deeply embedded, but that we will need to reframe this perspective to one of kinship to motivate people to care and make the loss of the living world real.

After months of deliberations, the government recently announced a partnership with the farming sector, with a five-year plan to quantify and price farm emissions by 2025. The announcement comes at the end of a consultation period on proposed changes to water quality legislation, and Mike Joy, also at VUW, argues that the strong links between agricultural emissions to the atmosphere and water should have been considered.

Climate Explained continues and this week explores why Mars is a cold planet, even though its atmosphere is mostly carbon dioxide, and political scientist Dominic O'Sullivan looks at Canada’s election results and whether a system of proportional representation, such as New Zealand’s MMP, would better reflect the will of the people.

Why water quality should have been an issue when NZ government joined with farm sector to curb emissions

Michael (Mike) Joy, Victoria University of Wellington

The New Zealand government's decision to partner the farming sector to encourage voluntary reductions in farm emissions failed to acknowledge that agricultural emissions also affect water quality.

What Canada can learn from New Zealand on electoral reform

Dominic O'Sullivan, Charles Sturt University

Unlike Canada's newly elected House of Commons, New Zealand’s parliament reflects the will of voters. So do other proportional representation systems. Canada has plenty of choice.
