| A chance constrained programming model is developed to assist Queensland barley growers make varietal and agronomic decisions in the face of changing product demands and volatile production conditions. Unsuitable or overlooked in many risk programming applications, the chance constrained programming approach nonetheless aptly captures the single‐stage decision problem faced by barley growers of whether to plant lower‐yielding but potentially higher‐priced malting varieties, given a particular expectation of meeting malting grade standards. Different expectations greatly affect the optimal mix of malting and feed barley activities. The analysis highlights the suitability of chance constrained programming to this specific class of farm decision problem. |

| Barley can be differentiated into feed and malting barley based on its end-use markets. Substitutability both in supply and in demand complicates analysis of price information in the barley market. The paper examines the price linkages between feed and malting barley in the Queensland barley market by using cointegration and error correction models. Malting barley prices respond to restore equilibrium relationships with corresponding feed barley prices in the long run, but not vice versa. Thus there appears to be a price leadership role for feed barley, and one-way substitutability and quality differences in the barley market. |

| Degradation of arid rangeland, and efforts to control that degradation, have become topical issues. However, the inherent characteristics of the rangeland, and the intertemporal nature of the problem, complicate the analysis of degradation issues in the search for more appropriate rangeland policies. Stochastic dynamic programming is examined as one means of allowing for those complexities. Using the case of the Queensland mulga rangelands, optimal stocking rates are shown to rise with lower property sizes, higher discount rates, higher wool prices and declining risk aversion. Importantly, the analysis reveals that a strategy of high stocking rates with the potential for rangeland degradation is an optimal response to the economic and social factors that... |

| Much has been written in recent years on ‘local state corporatism’, centre-region relations, government and enterprise reform and on sustainable rural and agricultural development in China. Based on some of the theoretical underpinnings of this literature, and on extensive fieldwork in the full range of administrative levels, this paper presents an institutional approach to one Chinese rural industry. For a number of reasons, the Chinese cattle and beef industry serves as a highly revealing case study. While the industry only began developing along commercial lines in the 1990s, institutional forces have been instrumental, and perhaps more important than market forces, in forging the industry along its particular development path. The paper highlights the... |

| A plant location model with two major aspects is outlined. First, discrete stochastic programming is used to handle variability in supplies and demands. Second, the cost structure of plants is modelled in more detail and with more realism than is usual. Results from applying the model to the Queensland cattle slaughtering industry demonstrate the inappropriateness of using traditional deterministic plant location models to analyse problems with major stochastic elements. Deterministic models yield plant locations, sizes, throughputs, commodity flows and implications which differ markedly from those generated by stochastic models in which plant sizes and locations are optimally matched to variable fat cattle supplies. In addition, the traditional... |

| In its ongoing efforts to identify more socially inclusive forms of development that target households in rural areas of Tibet, the Chinese central government has begun to focus more attention and resources on agricultural modernisation and development. Although agriculture continues to play a pivotal role in rural areas of Tibet, the nature of agriculture and rural society is changing.3 This paper first highlights some of the macro‐level changes that are occurring and some of the underlying drivers behind these changes. It then describes a model used to understand farm household systems at a micro‐level for the main agricultural areas of the Yalong river and its tributaries . The models explore the impact of agricultural innovations and changing... |

| Recent land reforms in China have sought to address fundamental problems with the Household Production Responsibility System such as land fragmentation. Primarily the reforms have targeted land productivity and grain output. However, the reforms have had a much broader effect on rural development as they have allowed a degree of household specialisation in non-grain activities both on and off the farm. Based on information collected from household surveys and fieldwork in Shandong and other provinces, this paper reports on some of the impacts of land reform on productivity, household specialisation and rural development. |

| This paper is concerned with improving the livelihoods of rural households in China — especially those involved in ruminant livestock production — in the context of market-oriented reform. Two broad categories of household are considered — diversified households and specialised households. Livelihoods are largely determined first, by the way the households interface with the industries or industry in which they are involved and secondly, by the development paths of these industries. Traditionally, the dominant Chinese approach to industry development is policy rather than market driven. Interventionist policies are introduced that target the construction of production bases with the aim of increasing physical output. At a later stage, attention turns to... |

| An examination based on stochastic plant location analysis was made of organizational efficiency in the Queensland cattle slaughtering industry. Short-run models were used to highlight forces influencing commodity flows and plant utilization levels in the industry. These models were also used to explore effects of freight equalization arrangements. Freight equalization was found to involve annual costs of resource misallocation of the order of $1 million. Potential efficiency gains through improved plant locations and sizes were also estimated and found to be at least $4.4 million. |

| This paper develops a heterogeneous-agent model to assess the impacts of removing lucerne growing subsidies, increasing livestock numbers and including district-level equilibrium conditions on optimal farm plans in the Qingyang district of Gansu Province, China. The model is a five-year dynamic linear program that solves across 96 farm households whilst incorporating district-level constraints. The approach used allows us to observe seasonal variations in incomes, infer the distribution of a policy shock among households and highlight trade patterns at the district level. The results suggest that without lucerne growing subsidies the total area of lucerne grown by all modelled households falls by 18%. Increasing livestock numbers by 25% reduces net... |

| From being an insignificant buyer of Australian wool at the start of the 1980s, China had emerged as Australia's major, if somewhat erratic, customer by the 1992/93 season. Continued development of Sino-Australian trade in wool is vital to the future of the Australian wool-growing industry. This article describes recent market and trade reforms in China and examines their likely impact on wool imports. Particular attention is devoted to the effects the recent changes will have on the up-country mills which represent a poorly understood but potentially significant new market for Australian wool. In many respects the problems/opportunities identified in relation to the up-country mills also exist for many other mills in China which, for various reasons, have... |
