This paper examines participatory budgeting (PB) as an instrument of localism – the devolution of political governance with the aim to produce sustainable democratic communities. This will be achieved through a detailed exploration of the decision-making mechanisms for creating local governance through PB schemes designed and organised by the Cornwall Council (UK). First introduced in the UK by the previous Labour administration in 2008, PB has become a tool of the Conservative-Liberal Democrat coalition government and is central to the neoliberal ethos of Big Society and localism. In a time of rapid political change, we respond to Eaton's [2008. From feeding the locals to selling the locale: adapting local sustainable food projects in Niagara to neocommunitarianism and neoliberalism. Geoforum, 39, 994–1006, 996] suggestion that greater attention be paid to “the specificities of particular neoliberal projects” by focusing on the micro-politics of PB. We draw upon empirical evidence from PB pilot schemes run in rural Cornwall in 2008, examining the effect of “nudging” decision-making. Grounding this inquiry in the existing literature on neoliberal statecraft, this paper investigates the role of government technologies which seek to frame local governance using mechanisms of libertarian paternalism [Painter, J., 2008. European citizenship and the regions. European Urban and Regional Studies, 15, 5–19; Painter, J., 2010. Rethinking territory. Antipode: A Radical Journal of Geography, 42, 1090–1118; MacLeavy, J., 2008. Neoliberlising subjects: the legacy of new labour's construction of social exclusion in local governance. Geoforum, 39, 1657–1666]. We argue in this paper that neoliberal ideology has integrated the epistemology of behavioural economics. We draw conclusions commensurate with the outcomes of PB projects conducted in Latin America, namely that citizens can be steered towards making certain decisions. We assert that in order to direct decision-making successfully, governmental “top-down” frameworks and goals need to be married with local geographies and “bottom-up” local desires and aspirations, thereby enabling a “countervailing power” [Sintomer, Y., Herzberg, C. and Rocke, A., 2008. Participatory budgeting in Europe: potentials and challenges. International Journal of Urban and Regional Research, 32, 164–178] to develop. This power is exercised by a participating and scrutinising citizen that contribute towards, and balance, governmental practices of PB. With a wider governmental emphasis on designing or “architecting” choice in opportunities for local governing, there is now an even greater necessity to recognise the context of geography in local government community-orientated initiatives. 相似文献

Solid waste is of serious concern in developing countries because of its high rate of generation and the low‐end quality of its management. Inefficient handling of solid wastes may result in deterioration of environmental quality, but it can also result in loss of potential resources. This study reviews current solid waste generation and management in Nigeria and the need for an effective collection, recovery, and recycling policy. Our review is based on literature searches and personal field surveys. Observations showed that uncontrolled electronic waste (e‐waste), agricultural‐waste (agro‐waste), scrap metals, waste polymers, and waste from the transportation sector are prevalent in Nigeria. Recent collection rates were less than 50% of the total solid waste generated (i.e., approximately 40% was collected). With an effective collection system and appropriate policies, the abundance of solid waste in the country could present material recovery and recycling opportunities that would boost the economy and move Nigeria closer to sustainable resource management. 相似文献

Snow is an important component of the hydrologic cycle for many regions worldwide. In addition to vital water resources, snowmelt can be important for forest ecosystem dynamics and flood risk. However, standard design events in the United States lack a design snowmelt event, including only precipitation events, though snowmelt has been shown to be larger than rainfall. In this article, we present a method using hourly snow water equivalent data to develop and test a function for representing the diurnal pattern of snowmelt. A two‐parameter beta distribution function is modified for the purposes of this study and found to fit the pattern of snowmelt well with a root mean squared error of 0.008. Soil moisture sensors were additionally utilized to assess the timing of the snowmelt water outflow from the base of the snowpack that supports the shape of the function, but suggests that the timing of losses recorded on snow pillows lag as much as 3 h. Further testing of the function showed the shape of the function to be accurate. The methods developed and tested in this paper can be applied for design purposes comparing snowmelt and rainfall events or to improve hydrological models investigating processes such as streamflow or groundwater recharge. 相似文献

Changes in Streambed Composition in Salmonid Spawning Habitat of the Elwha River during Dam Removal 下载免费PDF全文
Roger J. Peters Martin Liermann Michael L. McHenry Paul Bakke George R. Pess 《Journal of the American Water Resources Association》2017,53(4):871-885
One uncertainty associated with large dam removal is the level of downstream sediment deposition and associated short‐term biological effects, particularly on salmonid spawning habitat. Recent studies report downstream sediment deposition following dam removal is influenced by proximity to the source and river transport capacity. The impacts of dam removal sediment releases are difficult to generalize due to the relatively small number of dam removals completed, the variation in release strategies, and the physical nature of systems. Changes to sediment deposition and associated streambed composition in the Elwha River, Washington State, were monitored prior to (2010‐2011) and during (2012‐2014) the simultaneous removal of two large dams (32 and 64 m). Changes in the surface layer substrate composition during dam removal varied by year and channel type. Riffles in floodplain channels downstream of the dams fined and remained sand dominated throughout the study period, and exceeded levels known to be detrimental to incubating salmonids. Mainstem riffles tended to fine to gravel, but appear to be trending toward cobble after the majority of the sediment was released and transported through system. Thus, salmonid spawning habitats in the mainstem appear to have been minimally impacted while those in floodplain channels appear to have been severely impacted during dam removal. 相似文献

Predicting Satisfaction with Smart Irrigation Controllers and Their Long‐Term Use among Homeowners in Central Florida 下载免费PDF全文

Studies throughout Florida have shown smart controllers can substantially reduce irrigation under residential high‐water use conditions. However, successful promotion requires understanding the link between controller performance and the mechanisms by which they are adopted. This article compares irrigation water‐use and survey data collected from households installed with soil moisture sensor and evapotranspiration controllers. The study investigated whether the relative change in irrigation use between two years preceding and two years following installation was a reliable predictor of a homeowner's satisfaction with the device and likelihood of continuing to use it. Results indicated relative changes in irrigation use were only significantly associated with the quality of controller programming. Satisfaction with the controller was largely attributable to satisfaction with the appearance of the landscape and the perceived water‐saving effectiveness of the controller whereas the likelihood of its continued use was only significantly predicted by the level of technical knowledge regarding its functioning and whether or not challenges were experienced with it. Targeting homeowners with supplemental user‐friendly information may best support their long‐term adoption of smart controllers while providing irrigation contractors with training in implementation techniques would represent an integrated strategy for added reductions in residential outdoor water use. 相似文献

Bovine Tuberculosis and Badger Culling in England: An Animal Rights-Based Analysis of Policy Options
Steven P. McCulloch Michael J. Reiss 《Journal of Agricultural and Environmental Ethics》2017,30(4):535-550
Bovine tuberculosis (bovine TB) is an important and controversial animal health policy issue in England, which impacts humans, cattle and badgers. The government policy of badger culling has led to widespread opposition, in part due to the conclusions of a large field trial recommending against culling, and in part because badgers are a cherished wildlife species. Animal rights (AR) theorists argue that sentient nonhumans should be accorded fundamental rights against killing and suffering. In bovine TB policy, however, pro-culling actors claim that badgers must be culled to avoid the slaughter of cattle. The first part of the paper compares AR theories of Regan, Francione, Cochrane, Garner and Donaldson and Kymlicka in the context of wildlife species. The second part of the paper applies these AR theories to bovine TB and badger control. AR theories are applied to badger control policy options of (1) do nothing, (2) badger culling, and (3) badger vaccination. We conclude that AR theories are strongly opposed to badger culling. In general, culling is prohibited due to a badger’s right to life and its rights against suffering. The AR theories support a do-nothing, i.e. non-culling, non-vaccination approach to badger control. In the case of the AR theories of Regan and Francione, this is based on abolitionist positions with respect to farming. For Cochrane, Garner, and Donaldson and Kymlicka, the do-nothing policy option is preferred because badger vaccination causes a degree of suffering which generally is not for the individual’s benefit. 相似文献

In California, the growing popularity of urban agriculture (UA) has unfolded against a backdrop of historic drought. While UA is often celebrated as an urban sustainability strategy, it must be able to persist during drought if it is to perform these functions. Using Santa Clara County – the geographic core of Silicon Valley – as a case study, we use interviews and surveys to explore the implications of drought for UA. We show how developing an understanding of water access for UA during a drought requires examining the social and institutional context of water management and use. In metropolitan California, the highly decentralised water supply system combined with the diverse institutional arrangements that support UA create an uneven landscape of water access. Consequently, the pressure to change water-consuming practices – that is, the stress that institutional drought responses place on different water users – is geographically and socially differentiated. Among UA water users, responses to drought have also varied, in part because the possibilities for change are constrained by the sociotechnical arrangements of UA sites and the different purposes of UA. 相似文献

The power-voltage (P-V) characteristic curves of a PV array are nonlinear and have multiple peaks under partially shaded conditions (PSCs). This paper proposes a novel maximum power point tracking (MPPT) method for a PV system with reduced steady-state oscillation based on a two-stage particle swarm optimization (PSO) algorithm. The grouping method of the shuffled frog leaping algorithm (SFLA) is incorporated in the basic PSO algorithm (PSO-SFLA), ensuring fast and accurate searching of the global extremum. An adaptive speed factor is also introduced into the improved PSO to further enhance its convergence speed. Test results show that the proposed method converges in less than half the time taken by the conventional PSO method, and the power is improved by 33% under the worst PSCs, which confirms the superiority of the proposed method over the standard PSO algorithm in terms of tracking speed and steady-state oscillations under different PSCs. 相似文献

This study identified the changing preferences of country park visitors in Hong Kong and the potential for such changes to have further negative impacts on the ecologically sensitive areas of country parks. A questionnaire was used to collect feedback from 644 country park visitors to understand their preferences and visitation patterns. To investigate visitors’ preferences and behaviours and to develop better visitor management strategies, the survey data were compared with studies conducted 20 years ago. The results showed that the most popular nature‐based activities of 20 years ago, namely, picnicking and barbecuing, have significantly declined in popularity, while other activities, namely, nature studies and nature photography, have surged in popularity in recent years. These changes in visitor preferences have directly increased the negative impacts of visitors on country parks as they dispersed away from the high intensity recreation zones to the ecological sensitive areas. This emerging group of country park visitors has not been fully considered in the existing approach to visitor management and may irreversibly impact the ecological value of country parks. In this study, visitor management in Hong Kong's country parks was reviewed based on these research findings, and potential improvements were suggested. 相似文献

Though a recent phenomenon, land grabs have generated considerable debate that remains highly polarized. In this debate, one view presents land deals as a path to sustainable and transformative rural development through capital accumulation, infrastructural development, technology transfer, and job creation while the alternative view sees land grabs as a new wave of neo-colonization, exploitation, and domination. The underlying argument, at least theoretically, is that international land deals unlock the much needed capital to accelerate the achievement of sustainable and transformative rural development in developing countries. It is against this backdrop that this paper examines the contribution of large scale land deals in Malawi to rural development by employing the political economy perspective using the Limphasa Sugar Corporation as a case study with particular focus on the nature and interest of the actors involved; the legal framework supporting large scale land deals; major individual and community benefits; and the extent to which these large land deals can indeed bring about sustainable and transformative rural development. The findings of this article demonstrate that large scale land deals present short term benefits to local communities such as capital for rural development; technology transfer and job creation in exchange for the priceless economic and social capital that local people depend upon; destruction of local social systems; deepening of local communities’ vulnerability to economic shocks; and the entrenchment of community dependence that may in the long run result in social and political unrest. 相似文献
