Aquaculture is one of the fastest growing food‐producing sectors, and its share in global seafood production is rising significantly compared with capture fisheries. This transforms seafood production practices while allowing capital to expand to new marine commodity frontiers. Building on the conceptualization of aquaculture as a new frontier for capture fisheries, the article aims to uncover how commodity frontiers expand within the intensive marine aquaculture sector and shape the transformation of seafood production by focusing on its recent growth in Turkey. It analyses this transformation based on 22 in‐depth interviews with key social actors in Turkey, as well as a review of sector and state reports and the relevant legislations of Turkey and the European Union, and argues that the three‐pronged horizontal, vertical, and taxonomic expansion already observed in industrial capture fisheries has similarly taken place in intensive marine aquaculture through the commodity widening, deepening, and marketing strategies employed by aquaculture firms.  相似文献

The agro‐food sector has experienced a profound transformation of contractual arrangements along the value chain, coinciding with important technological innovations and product quality upgrading. Our understanding of the impact that this transformation has had on trade flows in the agricultural sector is very limited. In particular, we have limited knowledge about the extent to which the patterns in agro‐food trade have been driven by the quality of contractual institutions. Using existing measures which capture the sensitivity of agro‐food products to contractual imperfections, we show that countries with better contract enforcement specialise in the production of food which requires higher level of relationship‐specific investments. We also find that countries with better contracting institutions and producing contract‐intensive goods specialise in exporting high quality foods. In addition, we show that the quality of contracting institutions might importantly affect the process of product quality upgrading.  相似文献

The growing involvement of financial actors in food production has been one of the major recent transformations in the global agri‐food system. This ‘financialization’ of the agri‐food sector has been observed at various levels, from commodity speculation to direct investment in agricultural production, along with farmland itself. While there has been concerted effort to track new landownership and control associated with financial actors, especially in the Global South, there has been less impetus to examine the motives of financial actors' engagement in food production and the narratives upon which such engagement is based. This paper examines the way in which a productivist food (in)security discourse is employed by financial actors to legitimate their actions and to position themselves to win public approval. We analyse two cases of agri‐finance investors in the Australian context engaged in the discourse of food (in)security in relation to their agricultural investments – the Macquarie Group and Hassad Australia.  相似文献

Following the abolition of the milk quota in 2008, farmers in Switzerland strongly increased the use of concentrate feed in milk production. Against this background, the Swiss government introduced the voluntary grassland‐based milk and meat (GMF) programme in 2014, which combines economic incentives with feeding restrictions to reduce the reliance on concentrate feed and increase the use of grass feed. We analyse the economic and ecological impacts of the GMF programme at the farm and at the sector level in the short‐ and long‐run. We use a difference‐in‐differences approach (ex‐post) and an agent‐based simulation model SWISSland (ex‐ante) to construct counterfactual states to evaluate the programme's impacts. We find that the GMF programme reduces the use of concentrate feed and increases the use of grass feed in Swiss milk production. Whereas the programme has a positive effect on economic indicators such as the farm income, we find no effect on ecological indicators such as the N surplus. Our analysis suggests that feeding restrictions on concentrate feed are not enough to achieve a reduction in the N surplus. Additional feeding restrictions on grassland are necessary. Furthermore, the GMF programme has a dampening effect on sectoral milk supply, and leads to a higher milk price.  相似文献

Evaluating the possible benefits of the introduction of genetically modified (GM) crops must address the issue of consumer resistance as well as the complex regulation that has ensued. In the European Union (EU), this regulation envisions the co‐existence of GM food with conventional and quality‐enhanced products, mandates the labelling and traceability of GM products and allows only a stringent adventitious presence of GM content in other products. All these elements are brought together within a partial equilibrium model of the EU agricultural food sector. The model comprises conventional, GM and organic food. Demand is modelled in a novel fashion, whereby organic and conventional products are treated as horizontally differentiated but GM products are vertically differentiated (weakly inferior) relative to conventional ones. Supply accounts explicitly for the land constraint at the sector level and for the need for additional resources to produce organic food. Model calibration and simulation allow insights into the qualitative and quantitative effects of the large‐scale introduction of GM products in the EU market. We find that the introduction of GM food reduces overall EU welfare, mostly because of the associated need for costly segregation of non‐GM products, but the producers of quality‐enhanced products actually benefit.  相似文献

We analyze the long‐term impacts of large‐scale expansion of biofuels on land‐use change, food supply and prices, and the overall economy in various countries or regions using a multi‐country, multi‐sector global computable general equilibrium model augmented with an explicit land‐use module and detailed biofuel sectors. We find that an expansion of biofuel production to meet the existing or even higher targets in various countries would slightly reduce GDP at the global level but with mixed effects across countries or regions. Significant land re‐allocation would take place with notable decreases in forest and pasture lands in a few countries. The expansion of biofuels would cause a moderate decrease in world food supply and more significant decreases in developing countries like India and Sub‐Saharan Africa. Feedstock commodities (sugar, corn and oil seeds) would experience significant increases in their prices in 2020, but other price changes are small.  相似文献

There exists a large literature on price transmission in agro‐food sectors. However, a great majority of empirical studies focus on the existence of asymmetry and, by and large, do not investigate the reason for its presence or absence. This is in sharp contrast to the theoretical literature that provides a number of explanations of why we should expect (a)symmetry. In response, this paper investigates the reasons for asymmetric price transmission in the agro‐food chain, using meta‐analysis of existing studies. Our focus is on the organizational and institutional characteristics of the agro‐food supply chain. Our findings suggest that asymmetric price transmission in farm–retail relationships is more likely to occur in sectors/countries with more fragmented farm structure, higher governmental support and more restrictive regulations on price controls in the retail sector. On the other hand, more restrictive regulations on entry barriers in the retail sector and the relative importance of the sector tend to promote symmetric farm–retail price transmission. The latter is also more likely in the presence of a strong processing industry.  相似文献

While much effort has been devoted to estimating market premiums for non‐genetically modified (GM) food, the results of such research are largely silent about the preferences for the public good aspects, or externalities, of GM food production. For public goods, the closest substitute of private consumption decisions is voting on referenda. In November 2005, 55.7% of 2 million Swiss voters approved a five‐year moratorium (ban) on the commercial cultivation of GM plants in Switzerland. The present study examines how individual voting decisions were determined by: (i) socioeconomic characteristics; (ii) political preference/ideology; and (iii) agreement with a series of arguments in favour and against the use of GM plants in Swiss agriculture. The analysis is based on the data of the regular voter survey undertaken after the national‐level voting in Switzerland. The results suggest that current concerns about the use of genetically engineered plants in agriculture may not automatically decrease with higher levels of education/knowledge and generational change. Furthermore, analysis of voter motives suggests that public support for a ban on GM crops may be even larger in other countries, where industrial interests in crop biotechnology are less pronounced.  相似文献

In the National Innovation System (NIS), knowledge is produced and accumulated through interactive innovation processes that are embedded in a national context, which in turn may help determine innovation. This paper investigates how product and process innovations in the European food and drink industry are affected by: (i) NIS structure; (ii) NIS output in terms of scientific publications and the supply of graduates; (iii) NIS cohesion and coordination; (iv) NIS scientific impact and specialisation. The main source of data on innovation by firms is the EU‐EFIGE/Bruegel‐UniCredit dataset. This is supplemented by information from the International Handbook of Universities, Eurostat and a bibliometric analysis of academic research output. Our results suggest that large research institutions in the public sector may well be detrimental to interaction between university and industry and to process innovation. The indicators used for public research assessment are not necessarily the most appropriate proxies of local knowledge spillovers.  相似文献

Scaling up access to supplements designed to prevent undernutrition, such as new small‐quantity lipid‐based nutrient supplements (SQ‐LNS), may require distribution via both public channels and retail markets. The viability of SQ‐LNS retail markets will hinge on household‐level demand. We use an economic experiment to characterize initial willingness‐to‐pay (WTP) for a maternal SQ‐LNS product in Ghana. WTP is positive for most participants, though below the estimated cost of production for many. WTP varies depending on income, assets, and parity status. These findings have implications for the design of public health policy and hybrid public–private delivery mechanisms.  相似文献

We analyse European agri‐food firms’ choices about innovation in‐house or through outsourcing and provide empirical evidence about the correlation between these strategies. The relationship between the innovation strategy and firm‐, industry‐ and innovation‐specific characteristics is analysed through a bivariate probit model, which uses firm data from the EFIGE Bruegel‐UniCredit dataset. Transaction cost, resource base and knowledge governance arguments are used to explain the choice of innovation strategy. Our results show that the decisions to innovate in‐house or through outsourcing are independent from each other. In addition, we find that several organisational characteristics such as communication systems, human resource practices and specialisation are likely to influence both strategies. Conversely, organisational characteristics such as the allocation of authority and the business network do not seem relevant in determining the innovation strategies of the European agri‐food sector.  相似文献

This paper reports the findings of a study whose objectives were to compare and contrast the public and private sectors in Asia in terms of their (1) estimated level of investment in maize breeding research; (2) germplasm outputs; and (3) nature and extent of roles played in the maize seed industry. Since the 1960s, yield gains, rather than area expansion, have fuelled increases in maize production in Asia. Yield gains, in turn, have been due to the shift in maize cultivation from mostly open‐pollinated varieties (OPVs) to mostly hybrids. This transition also shifted the locus of modern maize breeding research from government research organisations to private national and multinational seed companies. In countries where both the public and private sectors participated in maize research, private sector research investment far exceeded that of the public sector. With more aggressive marketing programmes, the private sector captured 89% of the Asian maize seed market in the late 1990s. National public seed research agencies (including universities and cooperatives) developed and produced more maize OPVs than hybrids, mass‐produced and distributed seed cheaply, addressed location‐specific production problems, and provided agricultural extension services. The private seed companies developed, produced, sold and promoted their own proprietary hybrids. The reluctance of the private sector, however, to address the needs of marginal maize farmers should encourage the public sector to continue playing an active role in maize research and development (R&D), seed production and modern maize technology dissemination, especially with adequate support from appropriate government policies.  相似文献

This study investigates heterogeneous consumer preferences for nanofood and genetically‐modified (GM) food and the associated benefits using the results of choice experiments with 1,117 US consumers. We employ a latent class logit model to capture the heterogeneity in consumer preferences by identifying consumer segments. Our results show that nano‐food evokes fewer negative reactions compared with GM food. We identify four consumer groups: ‘Price Oriented/Technology Adopters’, ‘Technology Averse’, ‘Benefit Oriented’, and ‘New Technology Rejecters’. Each consumer group has a distinctive demographic background, which generates deeper insights into the diversified public acceptance of nano‐food and GM food. Our results have policy implications for the adoption of new food technologies.  相似文献

This symposium introduction brings together two debates; the debate on global food prices and speculation, and the debate on so‐called global ‘land investment’ or ‘land grabbing’. Both debates are examining two sides of the same phenomenon – the growing role of private financial investors in the global agri‐food value chains and the myriad consequences of it. The symposium moves beyond the identification of finance as an exogenous factor to the trends in the sector. It examines real‐life incarnations of finance in the sector by looking at investment arrangements, including connections with the state, and its (regional) variations. The symposium addresses three main themes. First, it explores the interplay of the state and private finance. It shows that the effect of regulation is limited in the face of increasingly mobile and complex investment flows. Second, it addresses the shifts and transfigurations of risk in the agri‐food sector due to financialization. Third, the symposium discusses to what extent, and how, the origins and identity of farmland investors still matters within an increasingly globalized financial sector. The paper concludes by identifying some related areas for further research.  相似文献

The strategic value of organic production and origin promotions may vary based on product end‐use. Conjoint analysis and eye‐tracking technology were used to investigate consumers’ purchase likelihood (PL) and visual search behavior for esthetic and food‐producing ornamental plants. Organic production methods, in‐state, and domestic origins positively impacted participants’ PL. Respondents’ visual attention to the organic production attribute had a strong positive effect on PL for food‐producing plants as did sociodemographic variables. Findings imply that producers and retailers could successfully implement signage emphasizing organic production methods and origin designations to generate consumer interest.  相似文献

This article provides an empirical analysis of the impact of European Union (EU) private food safety standards on pesticide use and farm‐level productivity among small‐scale vegetable producers in Kenya. We apply an extended three‐stage damage control production framework, accounting for multiple endogeneity problems, to farm‐level data collected from a random cross‐sectional sample of 539 small‐scale producers. Estimation results show that farmers producing vegetables for the domestic market use significantly lower quantities of pesticides than do export farmers. However, contrary to findings elsewhere, the econometric evidence here shows that both domestic and export‐oriented vegetable farmers in Kenya use pesticides at levels below the economic optimum. The results also show that the adoption of standards by export farmers does not have any significant impact on total pesticide use. However, adopter categories are distinguishable in terms of types of pesticide used, i.e. adopters use safer pesticides based on World Health Organization (WHO) classification. The third‐stage structural revenue model results demonstrate that adoption of standards has a positive and significant impact on revenue raised in vegetable production. Nevertheless, farmers producing for the export market are indistinguishable from those producing for the domestic farmers in terms of the total revenue earned from producing vegetables during the rainy season, on a ‘per acre’ basis. Although standards can potentially prevent resource‐poor smallholders from maintaining their position in the lucrative export markets, they can also result in positive changes in the production systems of those small‐scale farmers who adopt it, as shown by these results.  相似文献

This paper focuses on the direct impact of avian influenza outbreaks and the impact of the consequent non‐tariff measures (NTMs) on the international poultry trade. Using monthly export data from China and its 122 poultry importing countries, a random‐effect gravity model has been adopted. Emphasising the agri‐food trade in a global value chain context, the research analysis distinguishes between ‘agri‐food goods’ (mostly uncooked poultry products) and ‘processed goods’ (mostly cooked poultry products). The results show that domestic avian influenza outbreaks have a significant negative impact on a country's poultry imports compared with such outbreaks in exporting countries. Moreover, NTMs induced by avian influenza reduce the uncooked poultry trade but temporarily increase the cooked poultry trade. However, with a time‐lag, the cooked poultry trade may soon face increasing NTMs. The results also imply that developing countries that attempt to export agri‐food products to developed countries should increase and enhance processed food production.  相似文献

We use the classic agency model to derive a time‐varying optimal hedge ratio for low‐frequency time‐series data: the type of data used by crop farmers when deciding about production and about their hedging strategy. Rooted in the classic agency framework, the proposed hedge ratio reflects the context of both the crop farmer's decision and the crop farmer's contractual relationships in the marketing channel. An empirical illustration of the Dutch ware potato sector and its futures market in Amsterdam over the period 1971–2003 reveals that the time‐varying optimal hedge ratio decreased from 0.34 in 1971 to 0.24 in 2003. The hedging effectiveness, according to this ratio, is 39%. These estimates conform better with farmers’ interest in using futures contracts for hedging purposes than the much higher estimates obtained when price risk minimisation is the only objective considered.  相似文献

It is widely acknowledged that landscape features can play a major role in determining tourism demand. The present article assesses the impact of vinery landscape and high‐quality wine production on regional tourism flows in Tuscany, an important tourist region in Italy and renowned for its enchanting countryside. Thus, vinery landscape and high‐quality wine production have been included as explanatory variables in our model for tourism flows. This model has been estimated for both international and domestic markets for the whole region of Tuscany. Estimation results confirm that land areas devoted to the production of these superb Tuscan wines, in the particular case of Siena including the Brunello di Montalcino, play an important role in explaining international tourism flows. In this context, we estimate climate‐change‐induced impacts on vinery landscape and quality wines in the tourism sector. These are estimated to cause a loss in the tourism revenues of nearly 15 and 20 million Euros a year, respectively, for 2020 and 2050, for the Tuscany region. Such losses are quite significant, and reiterate the urgency to identify and implement adequate policy options so as to moderate such land use changes, and respective negative welfare impacts.  相似文献

This article presents results of a field experiment designed to assess willingness to pay for safely produced free‐range chicken in Hanoi, the capital of Vietnam. Improved safety of chicken production and trading is suggested as an important component of avian influenza control strategy, which aims to address the direct costs of avian influenza as well as the global public health externality. However, consumer demand for safely produced free‐range chicken is unknown. Products that have credible food labeling are not common in traditional markets where the majority of free‐range chicken is purchased. Valuing characteristics of products sold in informal markets is a major challenge that our experiment overcomes. As part of the experiment, we provided several vendors from these markets with safety‐labeled free‐range chicken. Consumer valuation of safety labeling was elicited through having experiment participants, who were representative of potential consumers, select between discount coupons for either safety‐labeled chicken or regular chicken. Results indicate that consumers will pay at least $0.50, or a 10–15% premium, per chicken purchase for safety labeling, which emphasizes safe production, processing, and transport conditions. This premium is smaller than the premium currently paid for traditional chicken varieties that are considered to be tastier. Consumers with more education have higher valuation of safety labeling. Hence, safety labeling for high‐quality free‐range chicken can play a role in controlling livestock disease and improving public health.  相似文献
