This paper provides an overview of the development of agricultural policy in Australia from a complex web of government intervention in the sector in the first half of the 20th century to the deregulation of the past 40 years. It highlights the close interrelationship between agricultural policy and manufacturing policy as well as the areas in which agricultural policy has been distinctive, namely the largely bipartisan nature of agricultural policy development and the strong cultural attachment across the community to farmers in general and family farming in particular. Recent policy debates suggest that agricultural policy will remain a sector apart in terms of the broadly bipartisan nature of policy and the ongoing influence of non-economic considerations. Australia will retain its comparative advantage in agricultural exports into the future and policymakers will need to continue to balance policies that support the economic performance of the sector with those that reflect community expectations of support for the farming community more broadly.  相似文献

Organic food consumption is one of several new trends in eating read as active opposition to industrialized food provision. While fast food consumption is characterized by compulsive gluttony, manifest in fat bodies, alternative consumption practices are seen to be driven by conscious reflexivity, such that consumers monitor, reflect upon and adapt their personal conduct in light of its perceived consequences. The purpose of this paper is two-fold. One is to examine the evolution of organic food from what Belasco called the 'counter-cuisine' to what organic growers call 'yuppie chow', to show how organic salad mix was the carrier of major changes in the organic system of provision, thereby calling into question the notion that organic food is necessarily an antidote to industrialized food. The other is to problematize the facile dichotomies between fast and slow, reflexive and compulsive, fat and thin, and, hence, good and bad eaters, to show where there is slippage and instability in these categories, in addition to a troubling politics of class and gender. To these ends, I showcase the changing provision of a particular organic commodity (salad mix, or mesclun) in California.  相似文献

Archaeological excavation of two late-18th century household middens in the San Blas parish of the colonial city of Riobamba resulted in the recovery of samples of archaeobotanical remains dating to the period before the AD 1797 destruction of the city in an earthquake. These seed remains were dominated by barley (Hordeum vulgare) and quinoa (Chenopodium quinoa). The dominance of these two grains in samples from artisans’ households in this marginal neighborhood suggests that we should question the assumption that imported Old World domesticates were associated with more elite houses during the Spanish colonial period in the Andes.  相似文献

By the early decades of the twentieth century, southern New England's Connecticut Valley had become a center of shade tobacco production and a destination for seasonal farmworkers drawn from sources inside and outside of New England. This paper explores the history of three groups of seasonal workers—children from area cities and towns; white southern high school students; and young African American men from southern high schools and black colleges—with an eye to assessing the impact of their presence on the form and meaning of the Connecticut Valley. My first goal is to add depth to the historiography of twentieth-century New England farming by drawing attention to the largely overlooked story of non-rural and extra-regional seasonal farmworkers. My second goal is to frame the case of Connecticut tobacco labor according to the study of mobility and its relationship to landscape. The mobility of workers into and within the region, I suggest, made possible the success of the shade tobacco economy while at the same time posing challenges to popularized cultural conventions about regional identity. For this reason, I argue, the history of Connecticut's shade tobacco landscape was informed by the efforts of shade tobacco growers to direct and control a confluence of environmental conditions, group and place-based identities, and the mechanics and meanings of mobility among seasonal workers. By hiring non-local, seasonal workers and by attempting to control their mobility, large-scale, corporate growers and their spokespeople ultimately sought to maintain control over the development and identity of the valley's rural landscape.  相似文献

Understanding social change within early village societies requires analysis at multiple scales. In this paper, we focus on macroregional structure in the Formative era of Central Mexico, based on excavations at village sites in Tlaxcala. A macroregional scale is particularly important for contextualizing developments in the study region. Rapid political evolution after 900 BC built on a legacy of organizational innovations in settled communities to the south. The earliest farmers in central Tlaxcala practiced a system of swidden agriculture developed at lower-lying elevations. Practiced on the erodible slopes of central Tlaxcala, that system led to the widespread degradation of farmland. Consequences at the village scale involved chronic instability of settlement and recurring localized stress on faunal resources.  相似文献

Palaeoenvironmental evidence for the character of lowland cultural landscapes during the last 2500 years in Britain is poorly understood, owing to a combination of an over-reliance on data from upland sequences, and because lowland mires are typically located in positions marginal to areas of settlement and agriculture. This paper presents an attempt to derive environmental evidence for this time period from a lowland context in order to characterise the key periods of change and continuity in the lowlands. The study focuses on mid-Devon, in South West Britain, and uses small pollen sites which are embedded within the historic landscape. The South West is a particularly poor region for lowland environmental data, and has until now been reliant on upland sequences. The results show that continuity, rather than abrupt change, has characterised the landscape from the later Iron Age to the early medieval period (around cal AD 800). There is no palynologically distinct Roman period in the data, contrary to evidence from the high uplands of Exmoor that suggests a decline of the agricultural system during the immediate post-Roman period. Around cal AD 800 there is a change in the agricultural system from predominantly pastoral activities to one that led to relatively high proportions of cereal pollen appearing in the sequences, which is interpreted here as marking the onset of convertible husbandry, a regionally distinct agricultural system which is recorded from AD 1350, but whose origins are not documented. This agricultural system remained in place until the post-medieval period, when the predominant agricultural regime returned to pastoralism around AD 1750. The data clearly show discrepancies between the high uplands and the lowlands, demonstrating the potential hazards of extrapolating upland sequences to lowlands environments.  相似文献

The pathways leading to the adoption of cereal cultivation and pastoralism in West Africa are poorly understood. In order to elucidate the transition to food production during the Late Stone Age in Mali’s Tilemsi Valley samples of ancient and modern human and animal remains were selected for carbon and oxygen isotope analysis. Our results indicate the inhabitants of Karkarichinkat Nord (KN05) consumed considerable quantities (85%) of carbon derived from C4 plants, either directly in the form of C4 grasses such as wild Panicum sp. and possibly domestic Pennisetum sp. or indirectly through the consumption of C4 grazers such as Bos sp. and Ovis sp.  相似文献

Some of the most politically and culturally significant cities in first millennium BC northern Mesopotamia were located in agriculturally marginal landscapes. In order to sustain these settlements, variant cultivation techniques were practiced by local populations. Understanding the dynamics and implications of crop management practices requires that socio-ecological variables be addressed over recurrent crop cycles. This paper employs a coupled socio-ecological modeling approach that enables interactions between a quantitative environmental model and an agent-based social model by using the ENKIMDU simulation tool. The reconstructed landscape near the ancient city of Assur is used as the example setting to test the effectiveness of simulated cultivation strategies. These methods include sole dependence on biennial fallow and rainfall, gravity flow irrigation, application of manure, and the integration of all these approaches. Results obtained within ENKIMDU attempt to delineate agricultural constraints and potential benefits of the specific anthropogenic processes and strategies addressed.  相似文献
