Agroforestry: Sustainable Agriculture in PNG

Agroforestry is a system of land use where harvestable trees or shrubs are grown to preserve or enhance the productivity of the land. It can include activity which is quite different from the conventional understanding of ‘forestry’ such as short-rotation fuelwood production systems in Papua New Guinea (PNG) which is currently being funded by ACIAR.

Dr Ian Nuberg, a senior lecturer at the University of Adelaide’s School of Agriculture, Food & Wine currently supervises the ACIAR research conducted in PNG.

Dr Nuberg, whose main focus is in agroforestry, specifically in the context of developing countries, works on two ACIAR projects run out of PNG. They are “Promoting diverse fuelwood production systems in Papua New Guinea” and “Facilitating the establishment of charcoal producer groups in Papua New Guinea

Tony Bartlett, ACIAR’s Forestry Research Program Manager, recently travelled to PNG to see how the research to produce and sell the fuelwood was going. To read about his experience click the link below:


Debate: Cutting Australia’s meat consumption by half will be better for us and the planet

These days, deciding what to eat is about more than just filling our stomachs. Increasingly we are asked to consider the effect that our food choices have on our communities and the environment, as well as ourselves. We are asked to eat foods that are produced sustainably, locally and ethically. “You are what you eat” has become “what you eat affects us all”.

Meat production is often targeted as having a large environmental impact. Different methods have been used to estimate the amount of water needed to produce a kilogram of beef varying between 500 and 50,000 litres, and methane emissions from ruminants are estimated to account for 10% of Australia’s total greenhouse gas emissions. Just over half of Australia is used for grazing animals, with more used to grow feed for more intensively raised animals.

In 2009 Australians, on average, each chewed their way through nearly 108 kg of meat, just over 2 kg per week, and we are one of the top meat-consuming nations of the world with only approximately 5% vegetarians. By comparison, the British ate 84 kg per person and the Chinese about 58 kg per person. The average meat consumption in India per person for the year, the lowest in the world, was only slightly more than what we consume in a fortnight at 4.4 kg. Our meat-heavy diet has been associated with chronic health issues and there are many that question whether it is morally right to raise and kill animals for food at all.

Reducing meat consumption is often suggested as a way to reduce our impact on the environment. But if Australia as a nation decided to halve our meat consumption, what would replace it in our diets? Is Australia’s climate and geography suited to producing the large amounts of plant foods needed to feed us? Could the water we currently use to produce meat actually be diverted and used for another purpose? Would we ever be the nation that says “throw another veggie on the barbie?”

This debate, moderated by Dr Paul Willis, RiAus, will explore all these issues, as six experts in two teams argue for your vote.
