NEXUS project: exploring profitable, sustainable livestock businesses in an increasingly variable climate (2020 - 2023)$1,170,292
Description
This is a collaborative project that will investigate future integrated grazing system designs using a collaboration from three new partners to the LPP. It also offers the opportunity for collaboration and linkage with existing LPP partners. The outcomes will form the basis for future R&D priorities in grazing systems along the entire east coast of Australia for LPP, MLA, SAMRC and NABRC. The project will directly contribute to the planning and implementation of the MLA and industry driven CN30 initiative and the RMAC Sustainability Framework. The project will identify a range of options for future grazing systems that:-will identify ways to deliver up to 3% ROA for a range of grazing systems in Tasmania, Gippsland, NWQld and the Northern Territory with methodology linkages to the MLA funded project investigating farming system options in NVic, NNSW and Central Qld and work being conducted by the NSW DPI Climate Group.-will be conducted in the context of significant known and predicted changes to climate parameters including temperature, rainfall and frost (including emerging new patterns and the incidence of extreme events)-examine the opportunity to diversify income from carbon mitigation projects under the Emissions Reduction Fund using new grasses or legumes, new supplements, and the integration of grazing management within carbon projects-examine the opportunity to diversify income and integrate into grazing or carbon management the emerging market for eco credits -will be developed using reference groups from the relevant SAMRC and NABRC regional committees and regional consultants to advise on system options-are assessed for their effectiveness as adaptation options using a number of metrics, including farm scale production, profitability, economic risk, farm-scale greenhouse gas emissions and the ease of implementation.The work in Tasmania will first calibrate systems models using existing management of representative sheep and beef farms in Tasmania. The number and location of case study farms will be conducted in consultation with SAMRC committee members. Model files calibrated based on grower/industry feedback will then be used to explore adaptations for each farm. Adaptations (hereafter, development options) will be selected in consultation with the SAMRC committee and may include changes to pasture base, animal genotype and/or management (hereafter termed development options). Development options in each region will be defined by a panel of producers to ensure they are regionally relevant. Examples of development options to be investigated could include: pasture (e.g. property scale integration of forage options, both existing and currently being investigated in feedbase research), animal (e.g. increased heat tolerance), management (e.g. integration of trees, increased livestock/live-weight throughput, optimising lifetime feed-use efficiency and selling strategies) and technology (e.g. virtual fencing). Following the approach conducted by the Uni Melb CC project, each development option will be evaluated in terms of profit targets, economic risk and farm-level greenhouse gas (GHG) emission intensity. The case study farm and development options will be analysed in historical and future climate scenarios based on projections for 2030.

Australian Dairy Carbon Calculator (2019)$14,000
Description
Since 1990, the Australian Federal Government has estimated the nations greenhouse gas (GHG) emissions, via the National Greenhouse Gas Inventory (NGGI), as part of their commitment to tackling climate change. More recently, the Australian government, along with 194 other countries of the world, agreed to adopt the first universal, legally binding global climate plan with the Paris Agreement in December 2015 (COP21). This agreement included the plan of avoiding dangerous climate change by limiting global warming to below 2C, and if possible, below 1.5C. The Australian dairy industry is the third highest ranked rural industry, with a farmgate value of AU $4.3 billion in 2017/18. The dairy industry has a carbon footprint of approx. 2% of the nations GHG emissions, based on NGGI methodology. The Australian Dairy Carbon Calculator (ADCC) was developed to allow individual farms to assess their GHG emissions. A metric of emissions intensity (EI) is the best way of comparing individual farm GHG emissions, taking into consideration all aspects of the farm system. The ADCC reports total farm GHG emissions and the EI of milk production (kg carbon dioxide equivalents (kg CO2e) per kg of fat and protein-corrected milk (kg FPCM) and per kg milksolids (MS)). The Australian government has set an economy-wide target to reduce total emissions by 26-28% below 2005 levels by 2030. There is currently no regulatory pressure in Australia to reduce on-farm emissions. However, as we pursue global neutrality of GHG emissions, to meet the COP21 Agreement targets by 2050, there is increasingly likelihood that farmers will need to demonstrate their carbon footprint profile before supplying milk to processors and accessing markets.This project has a strong focus on working closely with the Dairy Australia Dairy Farm Monitor Project team and Program Development Manager- Land, Water and Climate, along with milk processors and other relevant industry stakeholders to estimate the carbon emissions intensity of Australian dairy production. This information is required to report against the Australian Dairy Sustainability Framework Environment Target, 30% reduction in greenhouse gas emissions (GHG) intensity/unit of product by 2020 (baseline 2015). The scientific community if constantly researching mitigation options to reduce on-farm GHG emissions. While there are several currently available mitigations options (e.g. feeding dietary fats, improved reproductive performance, improved genetics to increase milk production per cow, strategic use of nitrogen fertilisers), in addition to promising future mitigation options (e.g. vaccination, methane-inhibiting feed sources). However, these mitigation options, in the medium term, are unlikely to deliver the complete removal of GHG emissions, and thus to the residual and unavoidable emissions will need to be offset through other avenues. There may be potential opportunities to sequester carbon, and thus generate carbon credits, through biodiversity/agroforesty plantings, to offset these residual emissions. Research reviewing potential sequestration options will form the basis of a new consultancy with Dairy Australia in the 2019/2020 financial year with new deliverables. The project has two key deliverables:Estimation of the EI of milk production for farms participating in the 2015-16 and 2016-17 Dairy Farm Monitor Project (approx. 100 farms across the eastern states of Australia) to inform the baseline for the Australian Dairy Sustainability Framework,Provide on-going technical support to Dairy Australia and the dairy industry with respect to the ADCC and other aspects relating to dairy GHG emissions.

LiveGAPS 2 Understanding livestock yield gaps for poverty alleviation, food security and sustainability (2017 - 2019)$119,004
Description
The productivity of livestock in the developing world is low, relative to its potential. There are significant opportunities to increase it via adequate mixtures of technologies, policies and investments in farms and product value chains. However, until recently, the baseline data needed to adequately characterize livestock productivity levels in different parts of the developing world was either not available, or not at a level of disaggregation necessary to make informed decisions on the upscaling potential of key interventions and their impacts on productivity and household nutrition and income. This is quickly changing due to new data sources but there is a significant need to study and synthesize the potential for productivity increases in smallholders systems for improved programmatic decision making and for targeting poverty and food security strategies.The Bill and Melinda Gates Foundation (BMGF) and other donors and development agencies need to target investments in the livestock sector in ways that are likely to maximize the impacts for broad numbers of producers and consumers. Estimating and understanding how to measure and trigger productivity changes in livestock systems is essential for better defining the technological and investment needs in the livestock sector. Estimates of livestock yield gaps are not available and these are necessary for developing feasible scenarios of how the production of different livestock commodities might evolve in the future, how systems might change and what would be the resource use implications and their costs, both for donors and for public and private entities in target countries. Productivity and yield gap analyses will also help define the most appropriate technology entry points for different livestock species: health, nutrition, genetics, policy levers, others. This information will contribute to making informed investment decisions and target technologies in the livestock sectors of developing countries as part of the SEBI grant coordinated by the University of Edinburgh on behalf of the BMGF.
