This region of Oceania comprises Australia, New Zealand, the island of New Guinea, and neighbouring islands in the Pacific Ocean. Its ecozone forms a distinct region with a common geologic and evolutionary history which has resulted in a set of unique types of animals and plants. Due to the reverse seasonality with the US and Europe, much food produce is exported to these countries in the winter from Australia and New Zealand. Except for the lush rainforest of Queensland and the east, much of the Australia is arid and unsuitable for arable agriculture. The country is considered highly vulnerable to climate change and associated impacts including droughts and wildfires.
This paper by FCRN member Jono Drew investigates whether healthy and climate-friendly diets might vary from global recommendations in the context of New Zealand (using food carbon footprints specific to New Zealand, where possible). It finds that shifting diets towards whole plant foods (such as vegetables, fruits, legumes, and whole grains) and away from red and processed meat would have large health and climate benefits, consistent with recent global recommendations.
New Zealand has introduced a new bill that aims to bring emissions of long-lived greenhouse gases to net zero by 2050. A separate target has been set for methane emissions from agriculture, with planned cuts of 10% by 2030 and 24% to 47% by 2050.
This paper by FCRN member Claire Pulker of Curtin University analyses the presence and quality of supermarket corporate social responsibility (CSR) policies related to all attributes of public health nutrition, including sustainability. The paper audited Australian supermarket own brand foods to establish the extent to which CSR policies are translated into practice.
This book, by David Lindenmayer, Damian Michael, Mason Crane, Daniel Florance and Emma Burns, describes best practice approaches for restoring Australian farm woodlands for birds, mammals and reptiles.
Labelling schemes to indicate higher welfare standards for broiler chickens have contributed to some changes in the governance of poultry welfare in Australia, argues this paper - but those changes are mostly incremental, and the labelling schemes may even bolster the perceived legitimacy of intensive poultry farming.
New Zealand’s Parliamentary Commissioner for the Environment has released a report exploring how much and over what timescale the climate is affected by methane emissions from livestock. It focused on two questions. First,if methane emissions from livestock were held at current levels or followed business-as-usual trajectories, what would their contribution to future warming be? Second, what reduction in methane emissions from livestock would be needed so that they cause no additional contribution to warming?
Fishers increase their fishing activity prior to the establishment of a new marine reserve, a new paper claims. The study used satellite data to study one particular marine reserve, the Phoenix Islands Protected Area (PIPA). While fishing effort dropped to almost zero after the marine reserve was established, fishing effort prior to the reserve’s establishment was 130% higher than in a control region (where no reserve was planned).
This paper examines some of the environmental trade-offs associated with using multilayered biodegradable packaging made of thermoplastic starch and polyhydroxyalkanoate.
This book, edited by Diana Bogueva, Dora Marinova and Talia Raphaely, explores how social marketing (which tries to change behaviours for the common good) can impact consumption of and attitudes towards animal products.
This blog by researchers Cedric Simon and Ha Truong from CSIRO Agriculture & Food discusses a method they have developed to reduce the amount of wild fish needed for prawn feed.

This report by Zero Carbon Australia, outlines how research on greenhouse gas emissions from land use (agriculture and forestry) can be reduced to zero net emissions, coupled with economic opportunities and increased resilience in the face of climate change. The land use sector is the second largest source of emissions in Australia and is highly exposed to the impacts of climate change. 15% of total emissions in Australia are from the agriculture and forestry sectors, the largest component of which is land clearing for grazing.
This study estimates the environmental impacts of what it terms discretionary foods - foods and drinks that do not provide nutrients that the body particularly needs. It finds that these foods account for 33-39% of food-related footprints in Australia.
Researchers from Conservation International have found a small island near Timor-Leste with staggering species richness. Atauro Island, home to about 8,000 people sits in the middle of the so-called Coral Triangle, known for its biodiverse marine environments.
The newly elected Australian conservative government makes a clear break from the previous government – led by climate skeptic Prime Minister Tony Abott – after announcing more funding for climate science.
The demand for meat is expected to double by 2050. Projections indicate that expanding the livestock industry to meet this demand would exceed biophysical limitations, dangerously exacerbating climate change and biodiversity loss. This paper uses an anthropological approach to explore an alternative meat source that not only avoids livestock’s pitfalls, but targets introduced pest species that have a history of profound destruction within Australian ecosystems.
A new green energy initiative has been launched by the Japanese meat processor NH Foods. Their Global Water Engineering (GWE) Cohral plant (in Australia)will extract green energy biogas from the waste water stream of production, replacing millions of dollars’ worth of natural gas currently consumed by the company factory. It is reported that the effect of burning the methane will save the equivalent of 12,000 tonnes of CO2, equivalent to removing 2,700 cars from the road.
