This study examines the effect of climate variability and climate change on the productivity of Australian cropping farms between 1977–78 and 2014–15. The productivity of Australian cropping farms is heavily affected by climate variability, particularly the occurrence of droughts. While Australian farmers are well accustomed to managing this variability, the emergence of climate change is presenting some new challenges.
This study combines ABARES farm survey data with spatial climate data to estimate the effect of climate conditions (such as, rainfall and temperature) on cropping farm TFP (Total Factor Productivity, i.e the combined productivity of labor and capital). The study then presents climate adjusted productivity estimates with the effects of climate removed. For comparison, similar results are generated for farm wheat yields using the same data sources and methods.

This report uses three scenarios to investigate the possible response of world food prices, food production and trade to the projected increase in demand. This work builds on agrifood modelling in ABARES Food demand to 2050: Opportunities for Australian agriculture (Linehan et al. 2012a).
The uncertainties and dynamics surrounding factors such as climate change, international trade policy and biofuels policies add to the complexity of modelling global agrifood markets out to 2050. However, scenario analysis, which isolates each of these issues, allows for an assessment of indicative price and production responses over the projection period across different regions and agrifood commodities. A reference scenario is developed for this project using a set of assumptions drawn from the literature. The reference scenario serves as a starting point for the policy analysis and shows the sensitivity of the projections to changes in assumptions and parameter values.

China’s economic growth and process of urbanisation are bringing about profound changes to China’s agrifood sector. With demand for agrifood products projected to double between 2009 and 2050, China’s agricultural sector is poised to contend with the challenges of depleting natural resource and rising input costs to maintain or improve productivity growth of most
major agricultural commodities.

With the population of China expected to increase to about 1.38 billion in 2050, the nature of food demand will depend on a number of factors, including income growth and urbanization. To investigate these developing trends, this study considers demand across three different income groups: urban high income, urban medium income and rural households. An updated version of the ABARES agrifood model (Linehan et al. 2012a) was used for the analysis. This model is an economic simulation model of global agricultural production, consumption and trade. In this report, agrifood products include primary agricultural products and lightly transformed agricultural products, such as flour and meat, but exclude highly processed food items. While it is projected that the majority of China’s future food demand will be met by an increase in domestic production, there are significant challenges with which the Chinese agrifood sector will need to contend to maintain or increase productivity growth. Investment in the industry is ongoing and required to ensure the degradation and availability of land and water resources, and rising costs for intermediate inputs, do not impede production growth.

The opportunities that Chinese demand growth will provide to food producers and exporters to 2050 are significant. To fully realize those opportunities, it will be important for Australian industries to utilize the working relationships with different agents in the food supply chain in China. For example, supermarkets and hypermarkets, which have an increasing presence in
urban food retailing in China, are playing an important role in meeting the demand for high‐value products by urban consumers. With higher incomes, urban consumers are also expected to increase their expenditure on convenience foods, fast food and restaurant food. Australian industries will need to be responsive to these changes if they are to successfully compete in the
Chinese market over the long term.
