Climate change and adaptations
Climate change is already affecting Australian farmers, with agricultural profits falling 23% over the 20 years to 2020 when compared to historical averages. Climate change could make conditions even tougher for Australian farmers and will require significant adaptation responses.
Farmers have a number of strategies for managing risks associated with short-term climate fluctuations, including maintaining relatively high levels of equity and liquid assets, using inputs conservatively, diversifying across enterprises and locations, and earning off-farm income.
In the last decade, a combination of productivity growth, better prices, and increases in farm size have resulted in an upward trend in farm profits. Much of the adaptation effort on farms has been directed toward improving performance under dry conditions. Within the cropping sector, for example, there have been a variety of management practice changes implemented in recent decades, including conservation tillage and soil amelioration, focused on preserving soil moisture.
Most broadacre cropping farms retain stubble, minimize tillage, and optimize the use of (and reduce reliance on) pesticides or fertilizers. Most livestock farms are using a variety of grazing management systems such as cell, strip, or rotational grazing and setting a long-term ground cover requirement.
To ensure the future of its agriculture industries, NSW is focusing on government policies and programs, and farm manager initiatives. These focus on climate-smart agricultural practices that aim to reduce greenhouse gas emissions and help farm owners and communities adapt to a changing climate.
Research is also being done to find ways of ensuring a continued agriculture industry and food supply, including developing crops and practices suited to future climate conditions, and changing the way land is used.

Sustainable practices
Many Australian farmers are already implementing sustainable land management practices. For example, most broadacre cropping farms retain stubble, minimise tillage, and optimise the use of pesticides and fertilisers. Livestock farms are also adopting various grazing management systems and setting long-term ground cover requirements. These practices not only benefit the environment but also improve farm productivity and profitability.
Enhancing farm dams can improve water quality and provide habitats for native wildlife, such as frogs. Shelterbelts, or windbreaks, provide shade and wind protection for livestock, mitigate erosion, and support biodiversity. They also help with natural pest control. Managing and restoring rocky outcrops and scattered paddock trees can boost farm biodiversity, productivity, and soil health.
To manage risks associated with short-term climate fluctuations, farmers are maintaining high levels of equity and borrowing capacity, using inputs conservatively, diversifying across enterprises and locations, and earning off-farm income. Strategic tree planting, technology for crop harvesting and irrigation monitoring, and employing young people are also ways that farmers are adopting sustainable practices.
Australia is also doing its part to improve sustainability outcomes by maintaining very low levels of support for farmers, reducing greenhouse gas emissions associated with food production, and contributing to improved agricultural productivity and reduced food waste.

Productivity growth
Australian farmers have had to adapt to the unique and often challenging environmental conditions of the country's various biomes. With a range of landscapes and climates, from arid deserts to tropical rainforests, Australian farmers have implemented a range of strategies to successfully cultivate crops and rear livestock.
One of the primary ways farmers have altered the biomes they work in is through land clearing. This involves removing native vegetation, such as trees and shrubs, to create open spaces for crops or grazing land for livestock. Land clearing can have significant environmental impacts, leading to soil erosion, reduced biodiversity, and altered water cycles. However, it has been a common practice in Australia, particularly in the early days of European settlement, to make way for agriculture.
Soil management is critical to farming in Australia's varied biomes. The continent is known for its ancient and nutrient-deficient soils, particularly in the vast interior regions. Farmers employ various techniques to improve soil fertility, including the use of fertilizers, liming to adjust soil pH, and crop rotation to replenish nutrients. In areas with poor-quality soil, such as the arid outback, irrigation techniques may also be utilized to enhance soil productivity.
Water management is key. Australian biomes experience unpredictable and variable rainfall, with frequent droughts and floods. Farmers implement strategies such as dams, reservoirs, and irrigation systems to manage water resources effectively. In drier regions, such as the Outback, dryland farming techniques may be employed, involving minimal water usage and the cultivation of drought-resistant crops.
Additionally, farmers carefully select and adapt crop choices to suit the specific biome they are farming in. This includes choosing crops suited to the climate and soil conditions and those resistant to pests and diseases prevalent in the area. For example, in Northern Australia's tropical regions, farmers may grow sugarcane or tropical fruits, while in the arid interior, drought-tolerant crops such as wheat or sorghum may be cultivated.
Finally, Australian farmers have addressed challenges posed by the country's unique fauna. This includes managing native wildlife, such as kangaroos and emus, which can impact crops, and controlling introduced pests, such as rabbits and foxes, which can damage farmland and prey on livestock. Strategies such as fencing, baiting, and culling are employed to manage these challenges and protect farms.

Risk management strategies
Agriculture accounts for over half of Australia's land use, so sustainable land management is crucial. Australian farmers have implemented various risk management strategies to address the challenges posed by climate variability, market fluctuations, financial obligations, government policies, and human factors. Here are some of the key risk management approaches:
Climate Variability
Farmers in Australia, particularly in semi-arid regions, face significant risks due to weather variability. To mitigate this, targeted climate knowledge, including seasonal forecasting and scenario analyses, can enhance preparedness and reduce vulnerability. For example, farmers can utilise climate information to implement strategies such as diversifying crops and adopting sustainable land practices. Most broadacre cropping farms in Australia retain stubble, minimise tillage, and optimise pesticide and fertiliser use to enhance sustainability and reduce the impact of climate variability on crop production.
Financial Risk
Financial risk arises from borrowing money and the obligation to repay debt. Farmers can manage this risk by maintaining relatively high levels of equity, liquid assets, and borrowing capacity. Diversifying income sources, such as earning off-farm income, can also help mitigate financial risks. Additionally, understanding interest rates, loan terms, and credit availability is essential for effective financial risk management.
Market Risk
Price or market risk refers to the uncertainty of commodity prices and input costs. The highly volatile auction system in Australia, which accounts for a significant portion of wool sales, presents a challenge for price risk management. Farmers can utilise forward contracts, futures contracts, and other hedging methods to manage price risks and stabilise their income. Diversifying across enterprises and locations can also help farmers manage market risks by reducing their dependence on a single commodity or market.
Institutional Risk
Institutional risk is associated with uncertainties surrounding government policies and regulations. Government decisions on tax laws, chemical use regulations, animal waste disposal rules, and price support payments can significantly impact farming operations. Staying informed about policy changes and engaging with relevant government departments can help farmers anticipate and adapt to institutional risks.
Human or Personal Risk
Human or personal risk encompasses factors such as health and personal relationships that can affect the farm business. To mitigate these risks, farmers can focus on employing and retaining skilled labour, providing training and supervision, and fostering a safe and supportive work environment. This includes addressing safety hazards, implementing engineering and administrative controls, and ensuring the use of personal protective equipment (PPE) when necessary.

Grassland biomes
Grasslands cover a large portion of Australia's landscape, from the tropical north to the temperate south. The country's latitudinal range, coupled with varying levels of precipitation, generates a diverse range of grassland environments. The grasslands in Australia are dominated by hummock grasslands, eucalypt open grasslands, and acacia open woodlands.
Hummock grasslands are found in the less fertile parts of the country and are composed primarily of spinifex or porcupine grasses. These grasslands, also known as "open woodlands," have several tree species, including acacia and eucalypt. Hummock grasslands cover most of inland Australia, and when it rains, they burst into colour with circular clumps of grass.
Eucalypt open grasslands are nestled within the true grasslands, while acacia open woodlands are primarily located in the south. These two ecoregions have a tree cover ranging from 10% to 30%, with the understory consisting of hummock or tussock grasses.
Grazing animals, such as cattle and sheep, are an integral part of grassland management and agriculture in Australia. However, overgrazing has been identified as a significant issue, leading to soil erosion and, in some cases, desertification. The introduction of exotic plants and animals by European settlers over two hundred years ago has also impacted the natural flora and fauna of these grasslands.
To maintain soil structure and support plant growth, farmers have utilised nitrogen fertiliser and herbicides for weed control. However, the low use of nitrogen fertiliser on grasslands in Australia, compared to other countries, is due to the high costs relative to the value of livestock products. Additionally, issues such as soil acidification and nitrate contamination of water supplies have arisen.
The dairy industry in Victoria and New South Wales relies heavily on pasture-based farming, with most farms consisting almost entirely of sown pastures. While the number of farms and farmers has decreased, there has been a significant increase in milk production per cow and per hectare.
Climate change, rising energy costs, and the increasing human population are putting pressure on Australia's grasslands. With more variable rainfall patterns and the need to feed a growing population, the future of grassland agriculture in Australia faces challenges that require innovative solutions.
