The purpose of this paper is to provide an economic analysis of the sources of supply to the US shrimp market.

The paper uses monthly time series data to estimate a simultaneous equations model with equations for domestic supplies from the Gulf of Mexico, imports, and prices.

Estimated long-run elasticities suggest that the domestic shrimp supply appears to be explained by seasons, diesel fuel price, hurricane activity, and shrimp price. The authors find evidence of a downward-slopping supply curve for the domestic harvesters that is likely to be temporary. Furthermore, anti-dumping duties have been ineffectual in curtailing imports produced by exploitation of natural shrimp biomass in developing countries and by technological advancements in aquaculture production. The authors also find evidence of a low exchange rate pass through. Finally, while domestic and import prices are not cointegrated, there is a two-way causality between them.

The authors found evidence that shrimp prices have fallen as import supply, due to technological advances in aquaculture, has risen faster than the US domestic demand over time suggesting a downward sloping supply curve. Also, the falling value of the US dollar has discouraged the imports, while the anti-dumping duties appear to have had little influence on the aggregate level of imports.

It provides a thorough investigation of the supply side of an important component of the US seafood market displaying the complexity of domestic producers’ reaction to falling prices, and ineffectual protectionism.

Anthropologists who study disasters share the widely acknowledged understanding that the effects of disasters tend to be more severe among economically and socially marginalized communities than others. Moreover, while poverty intensifies the effects of disasters, it also places survivors at the mercy of policies they have little control over because they often tend to be socially and politically marginalized on account of their poverty. Social vulnerability in other words is a determining factor in shaping the vulnerability of populations to catastrophic events. While scholars tend to focus on the catastrophic event itself as the locus of analysis, it has also become amply clear that such studies need to be in conversation with those that explore the long-term trajectories and effects of social inequality. Drawing upon fieldwork conducted in southern India among artisanal fisher communities affected by the tsunami of 2004, this paper argues that the conceptual aims and claims of the vulnerability concept ought to be extended beyond the confines of the disaster (conceptualized as event), to the broader historical sweep of unequal social relations of production, exchange and consumption within which such communities find themselves. Positioned at a disadvantage in relation to powerful players such as the state, multilateral entities and private big capital, such communities nevertheless might also become important loci of possibility, as they bring to bear their own critiques of power, and fashion political strategies that often frustrate and undermine the conceptual frameworks and goals of contemporary capitalist-led development.

This chapter reviews Colombia's unique environmental and social features and Colombia's realities in the third decade of the twenty-first century. It is crucial to understand the country's recent past and to take its structural and historic struggles into account when building sustainable futures.

This chapter also reports the findings of a primary data research study using futures scenario methodologies. The study participants represent different stakeholders' visions of four alternative futures regarding the climate crisis and massive biodiversity loss and social and economic crises.

This chapter's empirical study identifies Colombia's constraints to building a future that is just, inclusive and centred on nature. In addition, we describe in detail the structural changes needed for Colombia to achieve the best possible future scenario (socioeconomic prosperity and resilience to climate change). Finally, this chapter offers conclusions and recommendations.

This paper aims to address the issue of matching controlled vocabulary on agroforestry from knowledge organization systems (KOS) and incorporating these terms in DITA markup. The paper has been selected for an extended version from MTSR'11.

After a general description of the steps taken to harmonize controlled vocabulary on agroforestry, a general discussion of related work enriching documents and matching controlled vocabularies as well as details on managing controlled vocabulary in DITA are provided.

The paper identifies a number of practical and theoretical issues in matching controlled vocabulary from different sources, e.g. the complexity of addressing inconsistencies and incompatibilities between systems, and came across a number of approaches to semantically enrich documents, such as semantic‐document approach, facet classification, and integrating metadata and markup in documents.

Ways of incorporating controlled vocabularies into DITA markup are presented that can be drawn upon to guide future work in this area.

No previous work has reflected on the actual experience used to enrich DITA markup, especially with reference to the agrorestry domain.

Japan is the world's largest and most valuable market for shrimp. Per capita annual consumption is over 2kg annually, far greater than the United States (1kg) and the European Community (0.5kg).

The purpose of this paper is to assess the impact that the free trade agreement between the European Union (EU) and Chile and its resulting dismantling of tariffs has had on the mussel cultivation industry, particularly in Galicia. Specifically, the authors examine how trade liberalisation has affected the mussel farming industry.

The authors aim to observe the general panorama of both the evolution of production, distinguishing between fresh and industrial usage, and the evolution of prices at source depending on destination (fresh or industrial in the period 2003-2012). In order to analyse the relationships between different agents of the value chain, Porter’s model has been used as a reference.

There is a loss of competitiveness in the mussel farming-production sector following the liberalisation agreement of 2006 and huge bargaining power of the processing sector vs the production sector.

There is an opportunity to implement traceability programmes and develop a more differentiated product. In addition, it is profitable to promote Galician mussels through generic advertising and promoting exports.

There is a lack of empirical studies about the impact that the new free trade agreement between the EU and Chile has had on the Spanish mussel industry. Particularly, the study analyses economic repercussions, managerial implications and new challenges stemming from the new context of trade liberalisation.

The purpose of this paper is to identify the perceptions of farmers on the major sources of risk and to examine the effectiveness of the risk management responses of rural smallholder farm households in the semi-arid region of Northern Ghana from the socioeconomic perspective.

Both descriptive statistics and exploratory factor analysis were used on a Likert scale question to rank and identify the important risk perceptions and management strategies of the farmers. The linear regression model was used to highlight the significant factors that affect the farmers’ risk perception and management responses.

The effects of the variations in crop yield, fertiliser prices and crop price on household income were perceived as the three most relevant sources of risk. Stabilising household income by growing different crops, storing feed/seed reserves and spreading sales were the most effective risk management strategies. Factor analysis identified market risk, production risk and human risk as major risk factors whereas diversification, financial strategy, and off-farm employment were perceived as the most effective risk management strategies. Farm and farmer characteristics were found to be significantly associated with risk perceptions and risk management strategies. Risk perceptions significantly increase the risk management strategy adopted by the smallholder rural farmers.

The findings of the paper call for the integration of farmers’ risk perceptions and management strategies in the development of agricultural policies for the semi-arid regions of Ghana.

This paper deviates from the traditional technology adoption studies by modelling rural household perceptions and management strategies using, using descriptive, factor analyses, and linear regression.
