Government assistance and the changing distribution of dairyfarming in Australia

An important proportion of Australian dairy production has been destined for export markets, where prices are below those received on the home market. This degree of dependence on international prices has adversely affected dairy farm incomes and thereby influenced both Government responses to the industry's problems and dairymen's decisions about levels of production and farm viability. Examination of the spatial impact on the now declining Australian dairy industry of Government-funded subsidies and of schemes for reconstruction of non-viable dairy farms, has indicated that withdrawal of farmers from the industry has not been areally uniform at the national level; but study of a major dairying region whose industry has undergone substantial decline suggests that this uneven pattern reflects industry and regional characteristics more than the deliberate or inadvertent results of Government intervention. Although Government policy has been broadly directed towards reducing the numbers of dairymen, and hence dependence on overseas prices for production surpluses, industry change has been greatest in regions where viable economic alternatives have been available for low-income dairymen.     

Combined optimization of a wind farm and a well field for wind-enabled groundwater production

Energy requirements constitute a significant cost in groundwater production and can also add to a large carbon footprint when fossil fuels are used for power. Wind-enabled water production is advantageous as it minimizes air pollution impacts associated with groundwater production and relies on a renewable resource. Also, as groundwater extraction represents a deferrable load (i.e., it can be carried out when energy demands within an area are low), it provides a convenient way to overcome the intermittency issue associated with wind power production. Multiple turbine wind farms are needed to generate large quantities of power needed for large-scale groundwater production. Turbines must be optimally located in these farms to ensure proper propagation of kinetic energy throughout the system. By the same token, well placement must reconcile the competing objectives of minimizing interferences between production wells while ensuring the drawdowns at the property boundary are within acceptable limits. A combined simulation–optimization based model is developed in this study to optimize the combined wind energy and water production systems. The wind farm layout optimization model is solved using a re-sampling strategy, while the well field configuration is obtained using the simulated annealing technique. The utility of the developed model is to study wind-enabled water production in San Patricio County, TX. Sensitivity analysis indicated that identifying optimal placement of turbines is vital to extract maximum wind power. The variability of the wind speeds has a critical impact on the amount of water that can be produced. Innovative technologies such as variable flow pumping devices and aquifer storage recovery must be used to smooth out wind variability. While total groundwater extraction is less sensitive to uncertainty in hydrogeological parameters, improper estimation of aquifer transmissivity and storage characteristics can affect the feasibility of wind-driven groundwater production.     

Struggles over family land? Tree crops,land and labour in Ghana’s Brong-Ahafo region

Agricultural land use in much of Brong-Ahafo region, Ghana has been shifting from the production of food crops towards increased cashew nut cultivation in recent years. This article explores everyday, less visible, gendered and generational struggles over family farms in West Africa, based on qualitative, participatory research in a rural community that is becoming increasingly integrated into the global capitalist system. As a tree crop, cashew was regarded as an individual man’s property to be passed on to his wife and children rather than to extended family members, which differed from the communal land tenure arrangements governing food crop cultivation. The tendency for land, cash crops and income to be controlled by men, despite women’s and young people’s significant labour contributions to family farms, and for women to rely on food crop production for their main source of income and for household food security, means that women and girls are more likely to lose out when cashew plantations are expanded to the detriment of land for food crops. Intergenerational tensions emerged when young people felt that their parents and elders were neglecting their views and concerns. The research provides important insights into gendered and generational power relations regarding land access, property rights and intra-household decision-making processes. Greater dialogue between genders and generations may help to tackle unequal power relations and lead to shared decision-making processes that build the resilience of rural communities.     

Neo-liberalism, markets and class structures on the Nepali lowlands: The political economy of agrarian change

In recent years, neo-liberalism has manifested itself in peripheral social formations on an ideological basis through strategies of poverty alleviation. This process is epitomized by Nepal’s donor led agrarian strategy, which constructs farmers as ‘rational entrepreneurs’ responsible for their own welfare. In the process it seeks to encourage smallholders to shift from subsistence to market oriented production. However, over 10 years since the current agrarian strategy was released, there is little evidence of commercialisation and the integration of rural populations into global or domestic markets, while subsistence production remains dominant. To understand this failure, one must examine both the contradictions inherent in neo-liberal ideologies and the rural political economy of Nepal. While the emphasis on self-help through market access can be understood to be an ideological process constitutive of the overdetermined nature of capitalist expansion, contradictions are evident in such ideologies when they are mobilised in regions dominated by non-capitalist economic systems. The depoliticizing assumptions inherent in such ideologies can serve the interests of capitalist expansion through glossing over the associated forms of class exploitation. However, a case study from Nepal’s eastern lowlands demonstrates how they also divert attention from complex non-capitalist modes of surplus appropriation in both the relations of production and circulation. Such forms of exploitation have not only obstructed the process of classical agrarian transition long envisaged in Marxian theory, but have also blocked the emergence of the particular form of rural commodity production envisaged in Nepal’s neo-liberal agrarian strategy itself.     

Rn solution by the circulating fluids in a “hot dry rock” geothermal reservoir

The mechanism of²²²Rn release into fracture fluids by direct alpha-recoil, lattice and grain boundary/micro-crack diffusion is discussed. Experimental measurements of²²²Rn release into surrounding air and water phases have been made for crystalline rock specimens with well defined surface areas. The²²²Rn flux from an infinite plane surface and hence the effective diffusion length of²²²Rn in the rock matrix has been estimated.The²²²Rn flux from plane crystalline rock surfaces has been used in conjunction with a simple hydrological model of the reservoir to calculate the²²²Rn content of the return fluids of a geothermal doublet circulation system. For given production rate and piezometric difference between the injection and production wells, the²²²Rn content of the return fluid is dependent upon the distribution of flow path lengths and fracture apertures in the reservoir. Matching of the calculated and experimental²²²Rn contents of the return fluids has been used to select appropriate parameters for the reservoir model and hence to estimate the extent of the heat-transfer surface. The model estimates the fracture width of the flow paths, total swept surface area and fracture volume within the reservoir.     

Capital accumulation and regional development in France

The paper examines the interlinked development of social process and spatial form in the analysis of the changing patterns of production and employment in France. A major hypothesis is that specific phases of capital accumulation are associated with the use and production of specific forms of spatial diferentiation, and that recent changes in the location of employment in France are connected with the transition from one stage of capitalist development to another. Thus the changing spatial pattern of agricultural employment is seen as part of the decay of petty commodity production and the intergration of family farming into a new capitalist agriculture. Similarly, spatial change in manufacturing employment is also a component of industrial restructuring, and the associated development of new infrastrucural and labour requirements. The French state is one element of these processes and the article concludes with a case study of the relationships between capital accumulation and regional policy.     

A comparative electron microprobe study of “Aeginetan” wares with potential raw material sources from Aegina,Methana, and Poros,Greece

Qualitative stylistic evidence from ceramic vessels and limited petrographic analysis suggested that a distinctive group of ceramics with visible inclusions of biotite (Gold Mica Fabric) was produced on the island of Aegina, Greece, during the Middle Helladic and Late Helladic I periods. To quantitatively evaluate this provenance, we sampled all potential source rocks on Aegina, Methana, and Poros. Electron microprobe analysis of amphibole in these samples revealed that each of these volcanic centers has its own unique mineralogical signature. Comparative analyses of amphibole in Zerner's original stylistic “Gold Mica Fabric” type sample with the reference samples reveal that two sherds are Aeginetan. Three additional sherds from this sample may have a non‐Aeginetan provenance, probably from a back‐arc setting outside the Saronic Gulf. These results suggest that the hypothesis of a single source production site for Aeginetan Ware should be reexamined. © 2002 Wiley Periodicals, Inc.     

Part-time Farmig in Hungary

Part-time Farming in Hungary plays an important role in agricultural output. It provides 1/3 of gross production, half of the pork production and the majority of such intensive products as wine, fruits and berries, honey, etc. Part-time Farming has two basic forms: the household plots of collective farm members and employees and the small private farms of non-agricultural population. Half of the Hungarian families have such a farm activity, which is largely encouraged by the government. The flexible intregration of large scale (collective) farming and the private part-time farming was one of the keys in the recent agricultural successes of Hungary.     

Geoarchaeological investigations of the “potters' quarter” at Sagalassos,southwest Turkey

The potters' quarter of the ancient city of Sagalassos, southwest Turkey, was one of the largest and most enduring ceramic‐producing manufactories in the eastern Mediterranean. The objective of our study was to determine environmental circumstances that favored development of different clay resources in the territory of Sagalassos and to assess utilization of these resources in the local pottery manufactory. The potters' quarter was established where, owing to favorable geological circumstances, a large clay body had developed. The bedrock in the potters' quarter, a tectonized ophiolite sequence, has synclinal structure; hence, surface runoff and groundwater tend to accumulate in its center. The weathering of the basic rock formed a smectite‐rich clay with vertic properties. This clay was mined in antiquity, and mineralogical and chemical analyses indicate that it was used for the production of local ceramics from Hellenistic to Byzantine times. It is likely that colluvium on top of the ophiolitic clay at the potters' quarter is related to deforestation and slope processes after the potters' quarter was abandoned. In sum, environmental circumstances determined the location of the artisanal quarter of Sagalassos, with its clay quarrying operation and ceramic manufactory. However, for the local mass‐produced Sagalassos red slip ware, the results of our chemical and mineralogical analyses indicate that a different, more suitable clay was used: detrital lake sediments, rich in chlorite and chlorite/smectite mixed layers, located about 8 km from the original artisanal quarter. The choice for this clay was determined both by the presence of a suitable clay deposit, as well as socio‐economic circumstances such as land ownership. The site of Sagalassos yielded unique evidence of mining of clay at a ceramic production site, as well as import of nearby clays. The local and imported clays were used side‐by‐side, but one for the production of common wares and building ceramics, and the other for the manufacturing of luxury fine tablewares. © 2003 Wiley Periodicals, Inc.     

Sedimentological evaluation of general circulation model simulations for the “greenhouse” Earth: Cretaceous and Jurassic case studies

Conceptual climate models, based on the workings of the present-day climate system, provided a first-order approach to ancient climate systems. They are potentially very subjective in character. Their main drawback was that they involved the relocation of continents beneath a stable atmospheric circulation modelled upon that of the present. General circulation models (GCMs) use the laws of physics and an understanding of past geography to simulate climatic responses. They are objective in character. However, they require super computers to handle vast numbers of calculations. Nonetheless it is now possible to compare results from different GCMs for a range of times and over a wide range of parameterisations. GCMs are currently producing simulated climate predictions which compare favourably with the distributions of climatically sensitive facies (e.g. coals, evaporites and palaeosols). They have been used effectively in the prediction of oceanic upwelling sites and the distribution of petroleum source-rocks and phosphorites. Parameterisation is the main weakness in GCMs (e.g. sea-surface temperature, orography, cloud behaviour). Sensitivity experiments can be run on GCMs which simulate the effects of Milankovitch forcing and thus provide insights into possible patterns of climate change both globally and locally (i.e. provide predictions that can be evaluated against the rock record). Future use of GCMs could be in the forward modelling of sequence stratigraphic evolution and in the prediction of the diagenetic characteristics of reservoir units in frontier exploration areas. The sedimentary record provides the only way that GCMs may themselves be evaluated and this is important because these same GCMs are being used currently to predict possible changes in future climate.     

Energizing historical materialism: Fossil fuels, space and the capitalist mode of production

In this paper, I present a theoretical argument that fossil fuel represents a historically specific and internally necessary aspect of the capitalist mode of production. Despite sustained attention to distributional conflicts between international capital and energy rich nation-states, few historical-materialists have paid attention to the relations between fossil fuel and capital accumulation in industrial capitalist societies. In opposition to ecological economic notions of fixed thermodynamic “laws”, I first propose a dialectical conception of energy as embedded in dynamic social processes and power relations. Second, I review the historical importance of the energy shift from solar or biological sources of energy (muscles, wind, and water) to fossilized sources of energy (coal, oil, and gas). I then demonstrate how attention to fossil fuel energy forces a reexamination of the core insights of ecological Marxism and the political economy of nature. In the core argument of the paper, I reconsider the shift from biological to fossil energy as internal to the generalization and extension of capitalist social relations from two basic vantage points - (1) capitalist production based on wage labor; (2) the spatial conditions of capitalist circulation. I conclude by asking whether it is accurate to conceptualize capitalism as a “fossil fuel mode of production” and highlight the political urgency of a historical materialist perspective that takes seriously the importance of energy to the reproduction of capitalist social relations.     

The fate of foramol (“temperate-type”) carbonate platforms

On rimmed shelves of Bahamian-type, characterized by chlorozoan associations and typical of tropical seas, carbonate production keeps pace with normal sea-level rise except when rapid rise or drastic environmental changes occurs. On the other hand, open temperate carbonate shelves are characterized by low carbonate production of the foramol association (molluscs, benthic foraminifera, bryozoans, coralline algae, etc.) and generally show seaward relict sediments, because carbonate production cannot keep pace with normal rate of sea-level change.

Several examples of recent drowning foramol carbonate platforms (e.g., large areas of the Mediterranean Sea, eastern-northeastern Yucatan Shelf) as well as analogous ancient drowned foramol-type carbonate platforms (e.g., early to middle Miocene of the Southern Apennines; Miami Terrace) may support the idea that the drowning of many ancient carbonate platforms has been favoured by their biogenic (foramol sensu lato) constitution. Because of their typically low rate of growth, foramol carbonate platforms are fated to be drowned even if the sea-level rise is one with which the normal growth of chlorozoan platforms can keep pace. Similar conditions may also occur in tropical areas where variations in environmental conditions, such as the presence of cold waters, changes in salinity and increased nutrients, preclude the development of chlorozoan associations.     

Governing minorities and development in Xishuangbanna, China: Akha and Dai rubber farmers as entrepreneurs

In Xishuangbanna, southern Yunnan, Akha and Dai farmers, regarded in China as “backward”, passive recipients of state-led development, have been “getting rich” on rubber and expanding rubber cultivation into neighbouring Laos. State cash crop campaigns to raise minority farmers’ incomes inadvertently turned minority farmers into dynamic entrepreneurs. This paper builds on Vinay Gidwani’s use of development as a “regime of value” to raise social and economic value to analyze these unexpected results. Local state agents believe they are the agents of development, bringing modest social and economic improvements to minority farmers of obdurate backwardness. Minority farmers see themselves as improving their own incomes and “quality”, a term in China for social value, in an era when they are responsible for their own development. National development discourse encourages citizens to raise population quality by becoming entrepreneurial, a message heard by minority rubber farmers as well as urban elites. Through creative, post-Fordist production models and agile deployment of land, labour, and capital, minority farmers have achieved incomes that exceed those of workers on state rubber farms, large plantations whose Fordist production models are losing out in the uneven transition from a planned economy to a more capitalist market assemblage. Akha and Dai rubber farmers, the “backward” minorities on China’s periphery, have unexpectedly become the forerunners of flexible production arrangements that are prevailing in the arena opened up by China’s 2001 entry into the World Trade Organization.     

Cars and capitalism: The political economy of urban transportation

The car (automobile) appears to many to be an essential ingredient of capitalist society. This paper seeks to assess the role of the car in capitalist dominated social formations by relating the production, consumption and utilization of the car to the underlying structural relationships of the capitalist mode of production as a whole.     

Sociospatial aspects of Australian aboriginal underdevelopment. Empirical evidence from the East kimberley

Prior to the penetration of the European capitalist economy into central and northern Australia, the Aboriginal mode of production was one of hunting and gathering. Spiritual, economic and social relationships betwen people and land produced a spatial distribution of small bands of people living on their traditional lands. To the incoming white settlers the low population density and type of land use appeared uneconomic. This observation was used as ideological justification for the expropriation and development of the land for commercial pastoralism. This paper discusses the articulation of the Aboriginal and European modes of production in the East Kimberley region of northwest Australia. It argues that the introduced capitalist economy virtually destroyed the Aboriginal means of subsistence, incorporating Aborigines into the new mode of production within various subordinate roles. The exploitation of Aborigines, formerly as labour and now predominantely as consumers, is fundamental to the maintenance of the capitalist mode of production in pastoral areas. The spatial effects of the dominant mode of production have been to centralise Aborigines in locations suited to the various phases of development of the European economy, undermining the traditional Aboriginal social-spatial structure. The centralisation of the Aboriginal population also enhances the opportunities for the further development of the mining industry, which is in direct competition with Aboriginal interests in land. Aboriginal resistance to these spatial tendencies is intense in many quarters, but efforts to return to living on traditional lands and to develop alternative ways of living are hampered by the dominant mode of production.     

Cut Flowers in Warsaw

Cut flowers production around Warsaw depends mainly on very intensive methods, particularly the use of glasshouses, and includes a number of highly specialized farms. It is the result of a remarkably high level of demand in Poland and of the development of an export industry. It plays an important role in an agricultural system in which the production possibilities for very small farms are limited. Most production is in private hands and depends on the application of relatively large quantities of capital with a considerable element of risk. Farmers grow flowers at varying levels of intensity and with varying degrees of specialisation. A particular spatial structure within the general geographical distribution of intensive agriculture around Warsaw appears to have resulted. An attempt is made to indicate some of the elements in this structure by the use of published data for flowers production and for the taxation of private holdings by small administrative districts — the gminy or local communes. Examination of inputs indicates major constraints. The industry reached a peak in 1981. If it were to expand again attention should be paid to existing spatial diseconomies and the possibilities of relocation.     

The geoarchaeology of Iron Age “moated” sites of the Upper Mae Nam Mun Valley,N.E. Thailand. I: Palaeodrainage,site–landscape relationships and the origins of the “moats”

The study focuses on the “moated” Iron Age sites of N.E. Thailand, first identified as significant prehistoric settlement sites in the 1940s from aerial photography. Two more recent photograph sets are used to map the surficial geology and prehistoric site distribution for a study area west of Phimai, N.E. Thailand, with a focus on site–landscape relationships and, in particular, relationships between site location and form and patterns of palaeodrainage. The derived record of the surficial geology reflects several phases of palaeodrainage, characterized by differing locations and types of former river channels. Of note is the differentiation between a recent period in which river channels, including those presently active, are single-string meandering channels, and an older period of broad belts of meandering multistring channels. The prehistoric site distribution correlates closely with the older drainage, and for many, the encircling channels (the “moats”) are closely associated with former river channels. These relationships provide a critical and novel model for site distribution; several implications arise, supported by emerging field evidence, and introducing issues for archaeological debate: (i) there is no need, as has been done in the past, to invoke prehistoric artificial forms of drainage associated with the sites; (ii) the definition of the encircling channels as “moats” is seriously called into question; and (iii) the inferred geomorphological evolution of the floodplain implies past changes in environmental parameters such as run-off, climate or biophysical environments. Since the sites are all located in or beside ancient meander belts, these parameters should now be introduced into archaeological discussions regarding the establishment, history, evolution, and abandonment of the Iron Age sites. Methodologically, this article illustrates the need to be aware of the complexity of aerial photograph interpretation in archaeological survey, showing that careful analysis of aerial photograph information may have a significant impact upon the modeling of prehistoric interpretations. Further stratigraphical studies will be reported subsequently, and will refine the models presented here. © 1999 John Wiley & Sons, Inc.     

Ch’ixi landscapes: Indigeneity and capitalism in the Bolivian Chaco

Contemporary debates around the ontological turn have pitted efforts to take indigenous ontologies seriously against demands to make visible the forms of dispossession and environmental suffering that characterize the (post)colonial and capitalist present. Meanwhile, a growing array of governmental projects seeks to identify and protect indigenous ontologies in the face of capitalist development processes, including through forms of collective tenure. How can we make sense of such initiatives, and what kind of territories do they encounter and produce? This paper engages this question ethnographically through an examination of everyday life in a legally recognized Native Community Land in the Bolivian Chaco. Drawing on Bolivian Aymara scholar Silvia Rivera Cusicanqui’s notion of ch’ixi, I argue that indigenous territories are neither ontologically separate from, nor entirely subsumed by, capitalist development processes. Rather, they are subject to multiple land values, ontologies, and investments. A contested indigenous land titling process, capitalist labor relations, hydrocarbon compensation money, and efforts to maintain relations with spirit beings are all interwoven in the fabric of Guaraní everyday life. Such ch’ixi landscapes emerge at the confluence of capitalist efforts at rendering territories investable, governmental efforts at managing dispossession, and Guaraní efforts to maintain life and exercise territorial sovereignty amidst contradictory processes of (post)colonial governmentality.     

Wasting the rural: Meat,manure, and the politics of agro-industrialization in contemporary China

This paper uses pork as a lens on China’s rural transformations. Taking the industrialization of pig farming in the reform era as a trace on broader processes of social and environmental change, it advances three arguments. First, the massive increase in pork production and consumption since 1978 has been propelled by an industrial meat regime. A party-state led and agribusiness-operated regime, it articulates modernist notions of meat-as-progress with the relentless drive for capital accumulation. Second, using Marx’s concept of metabolic rift, the paper examines how processes of concentration in the industrial meat regime are at the same time processes of separation. This dialectical approach highlights the contradictions inherent in ongoing attempts to disembed capitalist production from biological and social relations. Finally, while official party-state discourse conceptualizes “the rural” as a production base for surplus value, and/or as a site for preserving environmental integrity, the paper’s analysis reveals a further unofficial recasting of the rural: in the process of agroindustrialization, the rural is also a sink for offloading capitalist crises. Between the rivers of manure that flow from industrial livestock operations and contaminate rural waterways; the loss of soil nutrients and food calories in the inefficient conversion of grains and oilseeds into industrial meat; the erosion of agricultural knowledge and practice that accompanies the dispossession of China’s farmers; and the shifting values of pigs, pork, and manure, this is a system that “wastes” the rural in service of capital.
