Soil Biology Masterclass – exploring the new frontier

This week the inaugural Soil Biology Masterclass was run at the Hawkesbury Institute for the Environment – University of Western Sydney. Soil biology is at the core of key processes underpinning agricultural productivity.

Nutrient cycling and availability, carbon storage as soil organic matter, soil water storage and movement, root and soil pests and diseases, are all determined or strongly influenced by soil biology. Our current management of soils, through tillage, fertilisers and pesticides, focus on the chemical and physical aspects, often to the detriment of soil biology.

Future improvements in agricultural productivity will increasingly be driven by soil biology.  We are now entering a period where the scarcity and cost of energy, nutrients and water are limiting productivity growth. However, the demand for food and fibre continues to grow.  New ways of explicitly managing soil biology is required to unlock low energy and nutrient input productivity. 

This is the fifth Masterclass I have been involved in developing and another incredibly challenging, stimulating and enjoyable group to work with. The mix of researchers from three Universities together with the diverse industry participants ( private consultants, farmers, policy-makers, EPA, advisors, commercial suppliers and R&D managers) produced a “hothouse” for the exchange of ideas, testing of assumptions and the collective development of new understandings and insights into the role of soil biology in agriculture and our ecosystems.

But don’t take my word for it have a read of Adrianna’s Soil Biology Masterclass blog

A second transformation of Australian landscapes

Inarguably colonisation and industry have changed Australia’s environment since the first fleet set foot on NSW in the late 18th Century. This first industrial age was built on natural capital, driven by the need to populate and establish, with unprecedented changes to the natural environment.

In some cases we have exceeded environmental and resource limits, a scenario echoing across the world.

A new paper, co- authored by Wayne Meyer from the Environment Institute suggests we are moving through a second industrial transformation of Australian landscapes. Wayne and his co authors including Kelvin Montagu, examine six emerging economies driving change in the Australian landscape; water, carbon, food, energy, amenity and mining.

These emerging economies could result in positive or negative transformations of Australia and the paper delves into some of partnerships and decisions we face as a nation to ensure a positive outcome.

This includes forming new partnerships between government, science, the private sector and communities, supported by renegotiated institutional settings and governance. Science has a pivotal role in getting the information we need to make these decisions and supporting effective strategies for positive change.

The paper is wide ranging in its scope, looking at local impacts and communities to generation- and nation-wide changes in how the country manages economies, environments and society. Overarching is the need to adapt to climate change and the global changes it will force in the absence of immediate and deep cuts to carbon emissions.

The authors provide  potential pathways to move forward, citing the need for vision and the power it provides towards solving these complex multidisciplinary problems.
