Genuine savings is a conceptually valid one‐sided indicator as to whether Australia is on a weak sustainability path (negative GS would warn that current welfare is unsustainable). The World Bank's adjusted net savings (ANS) data summarise the available evidence, and by this indicator Australia is muddling along, at best. ANS misses some important pieces of the picture – net depletion of water, soil and biodiversity, and most kinds of pollution damage – and thus overstates Australia's genuine savings performance. Weak sustainability can be promoted by getting the prices right, and piecemeal efforts are underway via regulatory approaches and resource/environmental markets of various kinds. Nevertheless, particular resource problems – habitat conservation, biodiversity, climate change and dryland salinity – are likely to also require strong sustainability approaches. A sustainable future involves pushing weak sustainability as far as the body politic permits, invoking precautionary instruments for specific resource crises, and nurturing policy processes that encourage the consensus‐building that will be necessary to get it done.  相似文献

We provide explorative insights on how farms which manage strong and successful growth affect farms in their neighbourhoods through spatial competition for land. The study is based on an exploratory analysis of repeated framed experiments within the business game FarmAgriPoliS (Appel & Balmann, Ecological Complexity, 40, 2019). In particular, we analyse the spatial influences of different behavioural clusters of farm managers. Our analysis finds that farms which manage strong growth substantially affect the development of farms in a spatial neighbourhood of some 10 km. Although the influence on the neighbourhood decreases with distance, the functional correlations of farm growth as well as exits are neither linear nor exponential, but eventually rather wave-like. We further discuss the spatial interdependence of farms and the related overlaps of the predator–prey phenomenon with the phenomena of farms' path dependency and agricultural structural change. We conclude that along with farmers' strategies and their abilities, the characteristics of their neighbours and the distances between neighbouring farms also determine who is ‘predator’ and who is ‘prey’.  相似文献

The data from long-term management and cropping systems experiments are needed to assess changes in soil quality, organic carbon pool, and agronomic sustainability. Thus, a 13-year-old soil fertility management experiment was used to assess the impact of crop residues carbon (C) inputs on SOC stock in a rainfed groundnut (Arachis hypogeae L.)–fingermillet (Eleusine coracana (L.) Gaertn) rotation in semiarid alfisol. The application of farmyard manure (FYM) alone or in a combination with chemical fertilizers contributed to higher amounts of C inputs and subsequently to build up a higher SOC pool. Application of 10?Mg?ha?1 of FYM and a recommended dose of chemical fertilizer (25:21.8:20.7 and 50:21.8:20.7?kg?N, P, K ha?1 for groundnut and fingermillet, respectively) increased soil SOC pool by 41.2% to 73.0?Mg?ha?1 with an increase of 9.3?Mg?ha?1 over 13 years. Both SOC pool and rates of its sequestration were positively correlated with cumulative C input and sustainable yield index. A minimal input of 1.62?Mg?C?ha?1?yr?1 is needed to maintain SOC pool at the antecedent level. Balanced application of NPK fertilizers is needed to reduce and reverse the depletion of SOC pool.  相似文献

Since the inception of supply management in Canada during the 1970s, milk production quota has been used to regulate output and participation in the dairy industry. In recent years, milk quota values have increased dramatically, almost tripling in value since the mid 1980s. This led to the Dairy Farmers of Ontario intervening on the milk production quota exchange on two occasions: first, in November 2006 with a progressive transfer assessment and then in July 2009, replacing the former policy with a firm price ceiling—fixing the unit price of quota at $25,000. These policies represent a significant redistribution of economic benefits from milk producers selling their quota to those remaining in the industry. The objective of this study is to first explore the reasons for the increase in production quota values; and second, to assess the welfare and distributional effects of each of the two quota policy schemes. Our results suggest that the increase in quota values were driven by basic economic factors and that the efficiency losses from intervention in the quota exchange are nontrivial. We conclude by suggesting there are several alternative policy options that could minimize efficiency losses while moderating the escalation in quota values. Depuis la mise en place du système de gestion de l’offre au Canada dans les années 1970, les quotas laitiers sont utilisés pour régulariser la production et la participation dans l’industrie laitière. Au cours des dernières années, la valeur des quotas laitiers a fait un bond considérable et a pratiquement triplé depuis le milieu des années 1980. Cette situation a amené la Dairy Farmers of Ontario à intervenir à deux reprises dans le système d’échange de quotas laitiers : en novembre 2006, en imposant l’établissement d’un transfert progressif et en juillet 2009, en remplaçant la politique précédente par l’établissement d’un prix plafond ferme fixéà 25 000 $. Ces politiques permettent une importante redistribution des avantages économiques lorsque des producteurs de lait vendent leurs quotas à des producteurs qui demeurent dans le secteur. La présente étude visait d’abord à examiner les raisons qui sous‐tendent l’augmentation de la valeur des quotas de production et ensuite àévaluer le bien‐être et les effets distributifs de chaque plan de quotas. Les résultats de notre étude autorisent à penser que l’augmentation de la valeur des quotas a été motivée par des facteurs économiques fondamentaux et que les pertes d’efficacité découlant de l’intervention dans les échanges de quotas n’étaient pas sans importance. En conclusion, nous estimons qu’il existe plusieurs politiques de rechange qui pourraient minimiser les pertes d’efficacité tout en modérant l’escalade de la valeur des quotas.  相似文献

Sustainable development is the underlying policy behind the community right to buy land in rural Scotland enshrined in the Land Reform (Scotland) Act 2003, Part 2. The Act explicitly requires communities wishing to exercise the right to buy to have sustainable development at the heart of their community body and all their plans for the land. This paper examines the role and interpretation of sustainable development in the CRB. Since the Act was passed three administrations have headed up the Scottish government and sustainable development issues and strategies for Scotland have been aired in four important and distinctive policy documents showing that it is still very much an evolving concept in Scottish politics. The current administration has adopted the most econocentric approach yet seen in the UK, focusing on sustainable economic growth. Meanwhile, the community right to buy has developed its own sustainable development agenda. This review of decisions taken under the legislation illustrates that a diverse range of community ownership plans have been deemed consistent with sustainable development, from creation of sports facilities to preservation of castles, lighthouses and village greens. A range of economic, social and environmental objectives have been approved. On the other hand, communities that fail to adopt the ‘right’ approach to the principle will not be successful in using the legislation.  相似文献

An online survey was conducted to investigate Japanese consumer preferences for fresh grapefruit based on prices and external fruit quality. The impact of 4 types of peel disorders (windscar, rust mite, melanose, and greasy spot) was investigated. Results from a discrete-choice model based on consumer responses indicate that willingness to pay for Extra Class fruit (no to little visible damage) is 1.5 times higher than the average willingness to pay for Class II fruit (highest level of visible damage allowed). Additionally, consumers revealed different utility levels depending on the type of peel disorder.  相似文献

It has frequently been assumed that the International Monetary Fund (IMF) plays an important catalysing role in mobilizing international capital for developing countries and countries in transition. The Fund has conventionally been depicted as a "gatekeeper" that unlocks financial flows from other sources, particularly private international capital markets. However, more recently, international financial crises have highlighted the problem of capital volatility and have led to calls for reform of the international financial architecture and, as part of this, the IMF. Unfortunately, basic questions about the interaction between current institutional arrangements and international capital markets have yet to be answered. How do international capital markets react to the activities of the IMF? Do the reactions of private and public lenders differ? Have their reactions changed over time? Do market responses depend on country characteristics and on the type of IMF involvement and, if so, how? This paper addresses these questions and goes on to discuss the policy implications that arise.  相似文献

Food safety regulations aimed at controlling food contamination have sometimes been criticised as excessive burdens, disadvantaging smaller firms and exports from developing nations. Reported food safety expenditures appear relatively small (from <1 to 7% of the value of production) but can erode profit margins for many firms. This article responds to claims that reported firm‐level expenditures do not reflect true costs of compliance with food safety systems. We estimate incidental cost savings and uncounted costs associated with Hazard Analysis and Critical Control Points (HACCP) certification among Philippine seafood producers by modelling the interactions between conventional production and food safety expenditures using translog cost functions. Results indicate a significant underestimation of reported HACCP costs by an average of US$1.10 for a dollar of reported expenditure.  相似文献

This explanatory paper describes and analyses which types of information professional property appraisers perceive to have the most impact on a commercial property’s estimated market value, which information sources they primarily use, and how reliable they perceive the information sources to be. The paper also investigates whether appraisers’ perceptions differ depending on the location of the business. A sample of 67 authorised property appraisers in Sweden was surveyed using the repertory grid technique as a questionnaire tool (to investigate unconscious behaviour), and non-parametric statistics. Analyses of the data show that four types of information have the greatest impact on estimated market value: the local environment and location are perceived as reliable, and property appraisers have confidence in those assessments; rental income seems problematic, because the property owner is the major source of information; and property appraisers are not confident in assessments based on discount rates. This pattern holds for various geographical locations.  相似文献

Qualitative field research in England identified a cohort of farmers practicing what they self-defined as ‘effectively organic’ or ‘semi-organic’ farming. Utilising Ajzen's theory of planned behaviour as a framework for analysis, reducing inputs was found to be primarily a response to financial pressures, also reflected in changing substantive norms towards balancing risks and potential returns against investment, rather than optimising production. However, despite the apparent ease of converting to organic farming from low input practice, formal conversion to organic farming was not found to be the automatic outcome of this trajectory: instead, organic farming was identified as only one of a number of options for increasing the financial viability of the farming operation, which included other niche markets, pluriactivity and contracting land to and from other farmers. The affiliation of low input farmers with organic production denotes positive attitudes towards both organic farming and environmental practices, but a lack of understanding about organic farming techniques. The author argues that due to declining returns/input ratios, future conversion to organic farming may reflect the value placed on other aspects of organic production, such as increased labour, risk reduction and environmental ideals, and highlights the environmental implications of the ongoing ‘cost price squeeze’ on farming households.  相似文献

This paper examines the determinants of female autonomy using data from India. We model female autonomy for movement as well as economic decision-making using a summative index approach. Our contributions to the literature include a careful examination of the regional differences, tests of economic and sociological hypotheses on female autonomy and the use of pre-marriage autonomy measures in terms of employment status to determine post-marriage autonomy. Our results suggest that economic, sociological and pre-marriage autonomy factors explain female autonomy. Regional differences regarding the economic, sociological and pre-marriage autonomy factors play a role in determining female autonomy.  相似文献

Abstract

The importance of agriculture in sub‐Saharan Africa, and the somewhat lagging development in other activities, suggests that particular significance attaches to the arrest of the drawn out crisis of agricultural production. Two opposing suggestions which are often made are that this is a matter either of price incentives, or of fundamental change designed to remove many infrastructural constraints and the lack of provision of other essential services. The issues are pursued, first, by an appraisal of the evidence relating to agricultural supply response. The long‐run response to price incentives is probably rather low, but it is suggested that it is very often constrained by non‐price factors. The paper then assesses the importance of infrastructural constraints, particularly in transport and communications. It is argued that the choices between improving price incentives and the need for infrastructure and other provision are not absolute since complementarities are important. Both, in effect, can also compete for public funds. The dilemma is particularly acute in sub‐Saharan Africa since low population densities and long distances result in the costs of transport and other essential services being comparatively high. It is therefore all the more necessary to seek cost‐effective ways of improving provision in order to maximize the impact on farm output. The paper suggests a number of ways in which this can be done, notably by better utilization of existing infrastructure.  相似文献

We conducted a nationwide choice experiment to gauge Canadian consumers’ willingness to pay (WTP) for local beef assigned with various mileage and geopolitical connotations. Results revealed that consumers are mostly indifferent between products labeled generically as “local” and as “local: from within 160 km,” implying that the 160‐km radius fits perception of local of the representative consumers. Additionally, consumers are willing to pay significantly more for home‐province products over products generically labeled “local.” We also found significant positive WTP for enhanced bovine spongiform encephalopathy tested beef as well as for grass‐ over grain‐fed beef.  相似文献

China's recent political and economic inroads into Africa have generated much interest in the current literature, with scholars and policymakers endeavouring to assess the merits and risks implicit in this renewed engagement. Absent from the literature, however, are systematic analyses of African perceptions of these rapidly growing China–Africa links, and what determines these perceptions. This article fills this void by examining not only African attitudes towards China's African presence, but also investigating the considerations that inform these views. Using multi-level modelling techniques, this article estimates the effects of Chinese foreign direct investment (FDI), Sino-African trade and notions of democracy and human rights on African attitudes towards “China-in-Africa”. The results suggest that Africans' views of China are nearly equivalent to those that they hold vis-à-vis Western countries. The perceived impact of imports from China has a negative effect. However, this effect is counter-balanced by perceptions of China's impact on poverty alleviation—in line with its greater focus on economic, social and cultural, as opposed to civic and political human rights—in particular through FDI. Among those who value civic and political human rights, in contrast, attitudes towards China are less favourable. This finding is echoed with respect to democratic governance, though the effect is less stable. The results are derived from Afrobarometer data covering 20 African countries.  相似文献

Although the Common Agricultural Policy of the European Union has broadened its objectives to integrate social issues, several hard-to-reach groups of farmers and workers continue to be ignored by advisory services and associated policies. Connecting with these groups has a strong potential to increase the economic and social cohesion of European agricultures. We interviewed over 1,000 farmers across Europe and identified features of these groups that are often overlooked by advisory services. We critically reflected on the social cohorts omitted from advisory services and how they could be better reached; they include farm labourers, new entrants or ‘career changers’, and later adopters. We clarify the different types of advisors in the advisory landscape, distinguishing between those who are linked to or independent from sales of inputs or technologies. We make concrete recommendations about how to engage advisors with hard-to-reach groups, with approaches suited to different national contexts of Agricultural Knowledge and Innovation Systems (AKIS); thus contributing to the ‘AKIS dimension of National Strategic Plans of the next Common Agricultural Policy, 2023–2027. We argue for the more effective use of advances in the social sciences through a better understanding of advice as social interaction which can bolster the inclusiveness of public policies.  相似文献

This paper assesses the efficacy and relevance of focus groups as participative tools for land use policy and planning. The use of focus groups has mushroomed in land use research and policy in response to new governance and empowerment agendas with their emphasis on using more deliberative and participative approaches. However, their use within social science research has been controversial given perceived methodological limitations of rigour and bias. A detailed critique of three recent research projects has been undertaken to assess focus group in theory and practice; rural diversification, public perception of landscape and visitor payback. The assessment considers key questions relating to inclusion, participation, empowerment, policy impact and understanding of complex policy issues. The results show that focus groups can perform multiple roles as exploratory, explanatory, participative and deliberative tools. Nevertheless, focus groups have important limitations and methodological protocols which demand more care and attention. Crucially, they should not be used in isolation to influence policy decisions; end user pressure for quick fixes, group dynamics, issues of representativeness, together with the biases of a facilitator, can easily mask, distort or misrepresent results. It is concluded that focus groups have significant potential as qualitative tools in landscape research but that they must be used carefully and in tandem with other techniques if their true potential is to be realised.  相似文献

Abstract

Consumers’ personality can influence choice behavior. Considering disparities between food store brand market shares across countries, we investigate the impact of personality on food store brand decision making. We carried out two non-hypothetical choice experiments for milk, ice-cream, and cereal, one in France and one in Germany for a total of N?=?505 participants. Results show that in France neurotic and in Germany conscientious consumers purchase significantly less store brands for the food items in question. This study contributes to the literature by providing evidence that both, personality and country-effects, influence consumer food choice behavior and serve as a motivating factor for multi-category purchases of grocery store brands.  相似文献
