Neoliberalism and the making of food politics in California   总被引:2,自引:0,他引:2  
Julie Guthman   《Geoforum》2008,39(3):1171-1183
This paper examines a philanthropy-led initiative which has as its objective to jump start the transition to a more sustainable and just food system in California. The first major project funded was a “vivid picture” of California’s food system twenty-five years in the future. The outcome of the project is a report that is glossed with the tropes of neoliberalism in all of its key organizing frameworks, analytics, cognitive maps, and idioms and argues for “opportunities-based approaches” as the engine of change. Yet, as described in the paper, this outcome was initially under-determined, and, in fact, the funders had originally intended to leverage their resources for large scale transformation. By examining four moments in the development of the Vivid Picture project, the grantee selection, the modeling exercise, the stakeholder meetings, and the qualitative interviews, this paper will show how existing techniques of neoliberal governance such as modeling, audit, best-practices, and stakeholder participation, as well as current norms of philanthropy, shaped what is thinkable and hence actable. It will also show how “stakeholders” played a constitutive role in producing the outcomes of the project, in part because their input reflected already-developed notions of the possible within the current climate of neoliberalism. In the end it will argue that the failure of the Vivid Picture to look beyond the neoliberal present is itself evidence of the proliferation of neoliberal governmentalities. Still, the entire process galvanized many of the movement actors who were left out of the funding process and, in that way, produced political openings.  相似文献

This paper assesses the possibilities and limits of efforts to incorporate social accountability into California agricultural production through voluntary certification and labeling, in the context neoliberal governance. We argue that, in its contradictory role as market mechanism, regulatory form, and social cause, certification both resists neoliberalization of the agro-food system and reinscribes neoliberal thinking. Unlike more traditional forms of social justice organizing, which have historically sought to alter power relations between labor, capital, and the state, the very notion that production conditions can be regulated through voluntary, third-party monitoring and labeling embraces several key neoliberal principles: the primacy of the market as a mechanism for addressing environmental and social ills, the privatization of regulatory functions previously reserved for the public sphere, and the assertion of the individual rights and responsibilities of citizen–consumers. Interviews with certification actors lead us to conclude that the strategic embrace of certification is driven by contradictory motivations within the movement for social accountability in agriculture, which can only be understood in relation to the confluence of a broader neoliberal political–economic order with California’s particular arrangements of farm labor politics and agro-food activism. Specifically, agro-food consolidation, rollback of protective labor regulation, the evisceration of the farm worker movement, and the conservative agrarianism of the sustainable agriculture movement intersect to circumscribe the realm of possibility and create conditions that undermine farm worker representation in the governance of agricultural labor practices.  相似文献

On August 31th, 2006 the California Senate shelved SB1056, a bill which would have granted the State jurisdiction over the regulation of seed and nursery stock. Ostensibly proposed to ensure “a level playing field” for agricultural and food producers, SB1056 is one of a host of legislation drafted across the United States to preempt county and municipal bans on genetically engineered crops. In California, the heated struggle around “preemption” exemplifies the interweaving of neoliberal ideology with industry attempts to prevent an unfavorable regulatory environment, but more importantly the contingencies and vulnerabilities of this strategy. After reviewing SB1056’s history, this paper examines how a diverse opposition movement capitalized on the friction between the neoliberal arguments mobilized by supporters and dominant Californian political philosophies. The paper then highlights the ultimate effect of SB1056 through a critical exploration of current state and federal regulation and the entrenched interests of the California government. I argue that more than simply opening new spaces for accumulation, SB1056 would have muted opposition voices and transferred power to institutions financially committed to the technology’s commercialization.  相似文献

Economic instruments are being promoted as a desirable alternative to public sector action in the allocation and management of natural resources. A wide body of literature has developed that critically analyzes this phenomenon as part of a wider project of ‘neoliberalization of nature’, trying to uncover the underlying rationale and commonalities of geographically specific phenomena. The case of water is at the vanguard of these processes and is proving to be particularly contentious. In the European Union water policies are increasingly emphasizing the application of economic instruments to improve the allocative equity and economic efficiency in the use of scarce resources. However, there are few analyses of how these instruments are really working on the ground and whether they are meeting their objectives. This paper aims to contribute to this debate by critically analyzing the experience with water markets in Spain, the only country in the European Union where they are operative. It looks at water permit sales during the 2005–2008 drought period using the Tajo–Segura transfer infrastructure. The paper describes how the institutional process of mercantilización of water works in practice in Spain. It shows that the use of markets requires an intense process of institutional development to facilitate and encourage their operation. These institutions tend to favor the interests of clearly identifiable elites, instead of the public interest they supposedly promote.  相似文献

Street vending faces uncertain state responses in contemporary Chinese cities, though it plays an important role in sustaining the livelihood of urban migrants. Building on the critical perspective that understands informality as a production of the state, this paper explores the nature of the regulation of street vending in Guangzhou since 1949. The state’s regulatory practices are characterized by what we call historical ambivalence and geographical ambivalence, which refer to the inconsistency in policies, which fluctuate between soft and hard approaches over time, and the mix of contradictory regulatory measures applied in different urban spaces, respectively. Ambivalence is generated because the state addresses street vending in ways that attain the overarching objective of urban policies. In particular, the exclusion of street vendors in present-day China is not historically natural but driven and sustained by the government’s pursuit of a good city image favorable for attracting capital in the context of intensifying inter-urban competition. The definition of informality is not a neutral classification. Rather, declaring when and to what extent an informal practice is tolerable depends on what the state desires in a specific historical circumstance.  相似文献

At scenic sites across China, rural officials compelled to maximize revenue use local state authority over protected areas to foster “tourism dynamos”. Local states set up infrastructure and institutions around rural attractions that channel the circulation of tourists, churning out revenues that meet quotas and fund further expansion of attractions and towns. To make these dynamos turn, local authorities have displaced resident-led tourism operations they had previously helped set up. Residents are reincorporated in varying ways and often retain land use rights. Meanwhile, as revenues stream out of attractions, what little is invested in environmental protection goes to maintaining scenery. Local governments also accomplish spatial transformations, within each park intensifying surplus generation in areas zoned for tourism while reserving other areas from use, and beyond park boundaries linking attractions together on tourism circuits radiating from central towns. This state-driven transformations depend on how the reservation of land from commodity exchange within protected areas comes together with specific state capacities to enable tourism intensification. These processes, which I label “developmental conservation,” call attention to selective commodifications and the mediating role of the state in protected area governance in China and beyond.  相似文献

In order to address the impacts of climate change, global multilateral institutions, development organizations, and national and regional science organizations are creating climate services – packages of useful climate information intended to help decision makers. This diffuse collection of actors and institutions suggest that producing climate services will help bridge gaps between climate scientists and decision-makers and will therefore help vulnerable countries and people manage the risks and optimize the impacts of climate change. This article examines this global science-policy ecosystem using the case of climate services produced by Australian science agencies for consumption in adaptation programming in the Pacific Island countries of Kiribati and Solomon Islands. Linking research on geographies of marketization and the neoliberalization of science, I demonstrate that within the climate service movement a focus on usefulness is paired with an emphasis on commercialization. As a result, this case shows the inherent tensions in the climate service model: first, a focus on competition and circulating service products at the expense of collaborative relationships; second, difficulties in negotiating uncertainty; and third contradictions between ‘objective’ and ‘entrepreneurial’ science. In each of these instances, the commercialized mechanisms through which climate services are governed, and the political economic circumstances within which they are produced, magnify rather than ameliorate gaps between science and policy.  相似文献

The objective of this critical review is twofold. Firstly, we intend to tackle a number of assumptions that view the Greek crisis as the result of a marked resistance to (neoliberal) structural reforms and the failure to engage constructively with the challenges of globalisation. Instead, we argue that Greece was set on a neoliberal trajectory much before the crisis erupted, and that it is precisely this sustained neoliberalisation process – rather than its absence – that lays behind much of Greece’s current troubles. Secondly, we attempt an assessment of the prospect that SYRIZA’s victory may be signalling the start of a counter-neoliberal mobilisation. Drawing on the work of Brenner and others, we identify four alternative scenarios – capitulation, divorce, compromise, transformation – and discuss their implications for Greece and the Eurozone.  相似文献

The institutions, practices, and discourses of US development policy and foreign assistance are undergoing profound changes. Central to these has been the creation of a new framework for foreign aid, built around a complex taxonomy of developing states and governance issue areas, with geographic and governance categories predicated on notions of state stability and fragility, strategic geopolitical position, and development progress. Given its long-standing position as the primary federal agency responsible for development and foreign aid, the US Agency for International Development (USAID) has played an important role in these policy changes, even as its political status and standing have suffered in recent years. The new framework is beset by contradictions, stemming both from the problematic relationship between development, security, and liberalization in agency rhetoric and strategies, and from intensive restructuring processes affecting USAID’s internal character and external relations. This paper investigates the new framework for foreign aid, linking internal restructuring at USAID to broader trends in state development strategies. I argue that shifts in US development and aid policy - toward emphases on “transformational development” abroad and centralization over strategic decision making domestically, crystallized in the new framework - are based in contradictory understandings of aid deservedness that stem from the tensions between economic and geopolitical aims within the current security-focused US state project of neoliberalization. These contradictions and tensions are displaced onto USAID via the Foreign Assistance Framework.  相似文献

分析了直线型KSS31M(SN035)海洋重力仪短期负漂移现象的原因、采取的处理措施和经验总结,认为在减震措施不足的情况下,重力仪长期经受震动,而频繁的搬动会使重力仪弹性系统中的金属弹簧产生较大的弹性疲劳,这种影响在短时间内无法完全消除,由此可能导致月漂移超标;陀螺稳定平台轴因承受震动磨损较严重,轴承间隙变大,导致安装在平台之上的重力传感器经过抛物线测试之后不能完全垂直指向地心,重力在水平方向存在一个微小的分量,最终导致重力读数偏小,即短期负漂移;重力基点环境的变化等对漂移也有一定的影响。建议在搬动重力仪后将仪器保持足够长时间的恒温后再开机,密切监测一段时间,以确保仪器处于良好的工作状态。  相似文献

Carbonate environments inhabit the realm of the surface, intermediate and deep currents of the ocean circulation where they produce and continuously deliver material which is potentially deposited into contourite drifts. In the tropical realm, fine‐grained particles produced in shallow water and transported off‐bank by tidal, wind‐driven, and cascading density currents are a major source for transport and deposition by currents. Sediment production is especially high during interglacial times when sea level is high and is greatly reduced during glacial times of sea‐level lowstands. Reduced sedimentation on carbonate contourite drifts leads to early marine cementation and hardened surfaces, which are often reworked when current strength increases. As a result, reworked lithoclasts are a common component in carbonate drifts. In areas of temperate and cool water carbonates, currents are able to flow across carbonate producing areas and incorporate sediment directly to the current. The entrained skeletal carbonate particles have variable bulk density and shapes that lower the prediction of transport rates in energy‐based transport models, as well as prediction of current velocity based on grain size. All types of contourite drifts known in clastic environments are found in carbonate environments, but three additional drift types occur in carbonates because of local sources and current flow diversion in the complicated topography inherent to carbonate systems. The periplatform drift is a carbonate‐specific plastered drift that is nearly exclusively made of periplatform ooze. Its geometry is built by the interaction of along‐slope currents and downslope currents, which deliver sediment from the adjacent shallow‐water carbonate realm to the contour current via a line source. Because the periplatform drift is plastered on the slopes of the platforms it is also subject to mass gravity flow and large slope failures. At platform edges, a special type of patch drift develops. These hemiconal platform‐edge drifts also contain exclusively periplatform ooze but their geometry is controlled by the current around the corner of the platform. At the north‐western end of Little and Great Bahama Bank are platform‐edge drifts that are over 100 km long and up to 600 m thick. A special type of channel‐related drift forms when passages between carbonate buildups or channels within a platform open into deeper water. A current flowing in these channels will entrain material shed from the sediment producing areas. At the channel mouth, the sediment‐charged current deposits its sediment load into the deeper basin. With continuous flow, a submarine delta drift is built that progrades into the deep water. The strongly focused current forming the delta drift, is able to rework coarse skeletal grains and clasts, making this type of carbonate drift the coarsest drift type.  相似文献

The Upper Cretaceous (Campanian–Maastrichtian) bioclastic wedge of the Orfento Formation in the Montagna della Maiella, Italy, is compared to newly discovered contourite drifts in the Maldives. Like the drift deposits in the Maldives, the Orfento Formation fills a channel and builds a Miocene delta‐shaped and mounded sedimentary body in the basin that is similar in size to the approximately 350 km2 large coarse‐grained bioclastic Miocene delta drifts in the Maldives. The composition of the bioclastic wedge of the Orfento Formation is also exclusively bioclastic debris sourced from the shallow‐water areas and reworked clasts of the Orfento Formation itself. In the near mud‐free succession, age‐diagnostic fossils are sparse. The depositional textures vary from wackestone to float‐rudstone and breccia/conglomerates, but rocks with grainstone and rudstone textures are the most common facies. In the channel, lensoid convex‐upward breccias, cross‐cutting channelized beds and thick grainstone lobes with abundant scours indicate alternating erosion and deposition from a high‐energy current. In the basin, the mounded sedimentary body contains lobes with a divergent progradational geometry. The lobes are built by decametre thick composite megabeds consisting of sigmoidal clinoforms that typically have a channelized topset, a grainy foreset and a fine‐grained bottomset with abundant irregular angular clasts. Up to 30 m thick channels filled with intraformational breccias and coarse grainstones pinch out downslope between the megabeds. In the distal portion of the wedge, stacked grainstone beds with foresets and reworked intraclasts document continuous sediment reworking and migration. The bioclastic wedge of the Orfento Formation has been variously interpreted as a succession of sea‐level controlled slope deposits, a shoaling shoreface complex, or a carbonate tidal delta. Current‐controlled delta drifts in the Maldives, however, offer a new interpretation because of their similarity in architecture and composition. These similarities include: (i) a feeder channel opening into the basin; (ii) an excavation moat at the exit of the channel; (iii) an overall mounded geometry with an apex that is in shallower water depth than the source channel; (iv) progradation of stacked lobes; (v) channels that pinch out in a basinward direction; and (vi) smaller channelized intervals that are arranged in a radial pattern. As a result, the Upper Cretaceous (Campanian–Maastrichtian) bioclastic wedge of the Orfento Formation in the Montagna della Maiella, Italy, is here interpreted as a carbonate delta drift.  相似文献

Tar residues are common on the coastline of the Monterey Bay National Marine Sanctuary. These coastal tar residues have been washed ashore and usually occur on headlands near the high-tide line. In this study, 18 coastal tar residues were collected and analyzed to determine their carbon isotopic compositions and the values of selected biomarker ratios. All of the residues have very heavy (13C-enriched) carbon isotopic compositions spanning a narrow range (δ13C = ?22.2 to ?23.4‰), and 28,30-bisnorhopane is present in all samples. These same geochemical characteristics are found in Monterey Formation oils from which the coastal tar residues were likely derived. These coastal residues could result from natural seeps or from accidental spills. Statistically the coastal tar residues can be organized into three groups, each of which may represent different spill or seep events. Seven samples of potential local representative sources for the tar residues were examined, but none could account for the coastal tars.  相似文献

Observations indicate that earthquake faults occur in topologically complex, multi-scale networks driven by plate tectonic forces. We present realistic numerical simulations, involving data-mining, pattern recognition, theoretical analyses and ensemble forecasting techniques, to understand how the observable space–time earthquake patterns are related to the fundamentally inaccessible and unobservable dynamics. Numerical simulations can also help us to understand how the different scales involved in earthquake physics interact and influence the resulting dynamics. Our simulations indicate that elastic interactions (stress transfer) combined with the nonlinearity in the frictional failure threshold law lead to the self-organization of the statistical dynamics, producing 1) statistical distributions for magnitudes and frequencies of earthquakes that have characteristics similar to those possessed by the Gutenberg–Richter magnitude–frequency distributions observed in nature; and 2) clear examples of stress transfer among fault activity described by stress shadows, in which an earthquake on one group of faults reduces the Coulomb failure stress on other faults, thereby delaying activity on those faults. In this paper, we describe the current state of modeling and simulation efforts for Virtual California, a model for all the major active strike slip faults in California. Noting that the Working Group on California Earthquake Probabilities (WGCEP) uses statistical distributions to produce earthquake forecast probabilities, we demonstrate that Virtual California provides a powerful tool for testing the applicability and reliability of the WGCEP statistical methods. Furthermore, we show how the simulations can be used to develop statistical earthquake forecasting techniques that are complementary to the methods used by the WGCEP, but improve upon those methods in a number of important ways. In doing so, we distinguish between the “official” forecasts of the WGCEP, and the “research-quality” forecasts that we discuss here. Finally, we provide a brief discussion of future problems and issues related to the development of ensemble earthquake hazard estimation and forecasting techniques.  相似文献

The Kirkgoz karst springs are in the well-developed Taurus karst zone in southern Turkey. Discharge is at an average rate of 15 m3/s. The large Kestel polje is 40 km from the springs and within the recharge area of the system. Utilization of the Kestel polje for agriculture as well as sewage disposal at sinkholes are sources of pollution. Water samples were analyzed for nutrients and some of the pesticides among the persistent organic pollutants. Although nutrient contamination is not critical yet, pesticide concentrations that range between 81 and 9,009 μg/l are above the international guidelines. This is the first record of pesticide contamination in karst systems in Turkey. Pesticides may be useful as tracers.  相似文献

Abstract ‘Peak’metamorphic carbon isotope fractionations between calcite and graphite (ΔCal–Gr) in marbles and calc-silicates from the Cucamonga granulite terrane (San Gabriel Mountains, California) range from 3.48 to 2.90%. The data are used to test three previously published calibrations of the calcite–graphite carbon isotope thermometer. An empirical calibration of the calcite–graphite carbon isotope thermometer gives temperatures of 700–750°C; a theoretical–experimental calibration of the system gives temperatures of 760°–870°C; an experimental calibration gives temperatures of 870–1300°C. Temperatures calculated using the empirical calibration are in agreement with those calculated from garnet-based cation exchange thermometry when uncertainty is considered. Temperatures calculated using the theoretical–experimental calibration overlap the upper range of cation exchange thermometry temperatures and range to 50°C higher. The experimental calibration yields temperatures from 50 to 480°C higher than those from cation exchange thermometry. Moreover, temperatures from the experimental calibration are also inconsistent with mineral and melt equilibria in the granulite phase assemblage. Despite the better agreement between cation exchange thermometry and the empirical calibration of the calcite–graphite system, temperatures calculated using the theoretical–experimental calibration may be real peak metamorphic temperatures. If retrograde diffusion partially reset garnet-based cation exchange thermometers by c. 50°C, then the cation exchange temperatures are consistent with those from the theoretical–empirical calibration. Thermometric evidence from biotite dehydration melting equilibria is consistent with either the empirical calibration if melting was fluid-present, or the theoretical–experimental calibration if melting was fluid-absent.  相似文献

This work diagnoses the present salinity of the Riguel and Arba Rivers (Spain) and predicts its expected evolution using geochemical models applied to the modernization of the actual Bardenas I and the completion of irrigation in the Bardenas II irrigation districts. The results show a progressive increase in salinity (from 0.39 to 2.21 dS/m electrical conductivity) in the Riguel-Arba system, due to the cumulative collection of irrigation return flows and its progression towards more saline facies. The Bardenas I modernization, involving an increase in irrigation efficiency from 50 to 90%, will decrease the volume and salinity of the Riguel River by 30%. In contrast, irrigation of the new 24,000 ha Bardenas II land will increase the flow (12%) and salinity (21%) of the Arba River. Geochemical models may help in providing sensible estimates on the impact of irrigation on the salinity of the receiving water bodies.  相似文献
