Speaker Profile

Adjunct Associate Professor Beverley Henry

Queensland University of Technology

Beverley Henry has worked in academic, agricultural industry and government roles for over 30 years, focussing on agriculture and land use sector science and policy issues with particular interest in climate variability, climate change, greenhouse gas accounting and sustainability science. She is an adjunct Associate Professor at Queensland University of Technology and is a member of several Australian and International technical and advisory committees.

Beverley’s expertise for the panel will focus on soil carbon sequestration in northern Australia’s grazing lands.

Diane Ouwerkerk

Principal Molecular Biologist, Department of Agriculture and Fisheries (DAF), Queensland.

Diane is a microbiologist and molecular biologist using innovative science to better understand the complex microbial communities found in the rumen, modify rumen efficiency, reduce enteric methane production, and minimise impacts of plant toxins on ruminants. Her overarching research goal is to achieve real and tangible impacts to improve the productivity, sustainability, and profitability of Australian Livestock industries. She leads the Microbial Ecology Group in the Emerging Technologies Team, Animal Science DAF, based at the EcoSciences Precinct, Brisbane. She has established a targeted, multi-prong research program aimed at decreasing enteric methane emissions to address national and international GHG emission targets.

Diane is undertaking research to equip beef producers with new tools to reduce greenhouse gas emissions from their enterprises through the development of a novel delivery system for active dosing of animals to suppress enteric methane, applicable to both extensive and intensive production systems. A collaborative project between the UQ and DAF will bring together new technologies, and diverse skill sets including chemical engineering, rumen ecology, nutrition, and chemical analysis. The successful development of a rumen insert for the controlled intra-ruminal release of methane supressing active-agents could provide one way to reduce methane from Northern Australia extensive grazing herds. Administered to cattle, it will ensure that each animal receives a sustained slow-release dose over an extended period with established reduction in methane emission, for application in both extensive and intensive cattle production systems.

Dr Nahuel Pachas

Senior Research Scientist, Forest Production and Protection, Department of Agriculture and Fisheries, Queensland

Nahuel is a DAF’s research scientist (PhD, MSc, BSc Agricultural Engineer) who has investigated silvopastoral systems, forestry and agroforestry, pastures (including leucaena-grass systems) and interactions between pastures, animal and trees in Queensland grazing and subtropical dairy production systems. His most recent work has focused on demonstrating livestock productivity and environmental service benefits of trees on farm in northern systems and he has undertaken silvopastural trials of commercial pine systems in North Queensland with a focus on integrating livestock and timber production. 

Nahuel has an expertise in silvopastural systems and will discuss opportunities for carbon neutrality, livestock productivity and environmental service benefits through the dual resource management of silvopastoral-systems in sub-tropical/tropical systems. With 48 million hectares of sub-tropical and tropical Queensland and northern NSW suitable for SPS hear the potential of SPS to:

  • mitigate GHG emissions
  • maintain economic sustainability across agro-ecological zones via income diversification and increased livestock productivity
  • sustainably use previously unproductive land
  • improve animal welfare and;
  • improve on-farm biodiversity.

Professor Richard Eckard

University of Melbourne

Richard Eckard is Professor of Sustainable Agriculture at the University of Melbourne and Director of the Primary Industries Climate Challenges Centre (www.piccc.org.au), a research centre addressing the impacts of a changing climate on agriculture. His research focuses on sustainable agricultural production, with a recent focus on carbon neutral agriculture and options for agriculture to respond to a changing climate.
