Description Australian dryland agriculture will be affected by climate change in a number of ways. First,
higher temperatures and changes to rainfall are likely to create greater variability of crop
yields and livestock productivity. Second, government policies introduced to mitigate
greenhouse gas emissions are likely to influence production costs and commodity prices.
Third, global trade patterns are likely to alter as populations increase, and as climate change
continues to affect producers and consumers worldwide. This will create both challenges
and opportunities for Australian agriculture.
Farmers will have to respond to the additional challenge of climate change even when it is
compounded by existing long term stresses associated with declining terms of trade, climate
variability and existing environmental issues. Investing in new land-use options to combat
climate change, with their associated risks, is made more difficult by being set against a
backdrop of declining profitability.
The opportunity to create transformational change in farming enterprises was tested by
combining the multiple components of the potential future perennial‐ based dryland farming
systems and assessing their expected contribution to climate change adaptation. This
project has found that adopting perennial pastures for livestock grazing and tree crops for
biomass production, when planted on appropriate soils, can improve profitability when
compared to the existing land uses facing a changing climate. In some farming systems
increased cropping is likely to result in improved future farm profits.
This work demonstrated that mallees as a biomass tree crop can be cohesively integrated
into existing farming systems with minimal interruption to normal operations of livestock and
cropping enterprises. A woody biomass crop can be profitable and diversify revenue risk by
enabling farmers to supply biomass and sequester carbon to relevant markets. This work
demonstrates suitable designs of a mallee belt planting layout that minimizes costs and
maximizes benefits when planted in appropriate agro‐ climatic zones and where there are
adequate soil conditions. Knowledge developed from this work will help build farmers
capacity about climate change adaptation and assist in achieving positive social,
environmental and economic outcomes.
