Bangladesh has experienced a rapid expansion of shrimp farming in the coastal regions in recent years. The increase in both area and production has been influenced by the financial profit motive of rural farmers coupled with high international demands for shrimps and ecological congeniality for shrimp aquaculture. In the past the traditional farming systems in the coastal belts of Bangladesh centred around rice crop. In contrast, the introduction of shrimp aquaculture on a larger/commercial scale has developed shrimp‐based farming systems. Shrimp farming itself is less labour‐intensive than rice cultivation, especially when extensive methods of shrimp culture are practised. Hence, it has reduced on‐farm employment opportunities for rural landless. Nevertheless, shrimp production requires a substantial volume of labour in off‐farm ancillary activities, namely shrimp fry collection, shrimp feed collection, and shrimp processing and packaging for export. Most of this off‐farm work is performed primarily by rural women. This process has engendered a major shift in rural employment and occupational structure in the shrimp belt. Shrimp production has enabled rural women to earn more cash income and to become more active income‐earning members in rural households. While they used to contribute to their share of agricultural work in the homestead before the shrimp cultivation was introduced, now they work mostly outside their homes. This has forced them to stay outside of their homes for longer hours, which limits their time for household duties, more specifically looking after children. All these factors together have implications for the socio‐economic changes in the rural society. The findings that emerge indicate that a range of factors including rural power structure, centre‐periphery issue, rural‐urban migration determine the pattern and extent of employment. It is unclear whether greater employment opportunities for rural women have empowered them or have helped extricate them from various forms of discrimination and exploitation.

This paper aims to investigate shrimp income losses of farmers in the four farming systems in the research areas of Ca Mau, Vietnam, and determine the vulnerability of shrimp farming income to climate change events.

Field research interviews were conducted with 100 randomly selected households across the four farming systems to access shrimp income status and vulnerability levels to climate change events. Four focus groups, each aligned to a particular farming system, were surveyed to categorise likelihood and consequences of climate change effects based on a risk matrix worksheet to derive levels of risk, adaptive capacity and vulnerability levels.

Shrimp farmers in the study areas have been facing shrimp income reduction recently and shrimp farming income is vulnerable to climate change events. There are some differences between farmers’ perspectives on vulnerability levels, but some linkages are evident among shrimp farmer characteristics, ramifications for each farming system, shrimp income losses and shrimp farmers’ perspectives on vulnerability levels of shrimp incomes. From an income perspective, farmers operating in intensive shrimp farming systems appear to be less vulnerable to existing and expected climate change effects relative to those in mixed production or lower density systems.

Having identified the vulnerability level of shrimp farming income to climate change events in different farming systems based on shrimp farmers’ perspectives, the paper adds new knowledge to existing research on vulnerability of the aquaculture sector to climate change. The research findings have implications for policymakers who may choose to encourage intensive shrimp farming to enhance shrimp farmer resilience to the effects of climate change as well as improving cultivation techniques for shrimp farmers. The findings could thus guide local government decision-making on climate change responses and residents of Ca Mau as well as within the wider Mekong Delta in developing suitable practical adaption measures.

Agricultural systems in Mekong Delta have transformed to cope with climate change. Various researches pointed out that integrated agriculture-aquaculture (IAA) farming systems (i.e., rice-shrimp, rice-fish…) emerged as potential climate adaptive practices. However, limited studies are attempting to assess the sustainability of these agricultural practices. Therefore, it is essential to assess whether or not these systems will be sustainable in the context of climate change and what can be done to make it sustainable. The present study conducted the sustainability assessment of the rice-shrimp system to identify potential areas for improvement as well as policy implication to increase resilience and adaptation of coastal IAA system which could contribute to the understanding of other coastal agricultural deltas around the globe.

This study used a quantitative approach including the assessment protocol of van Asselt et al. (2014), the assessment framework of Vanloon et al. (2005), and the MCA methodology to flexibly and holistically assess the sustainability level of agricultural systems.

Results concluded that rice-shrimp systems have the potential to improve livelihood, food security, and adaptation of coastal farmers. Major improvements should be considered for productivity, efficiency, and equity themes, while minor improvements can be made for stability, durability, and compatibility themes.

This research could be used as a guideline for sustainability assessment in a context-specific case study of IAA, which showed a potential for the application of other climate-smart IAAs in similar contexts around the globe.

The purpose of this paper is to investigate the determinants of the amount of trade credit granted to shrimp farmers in Ca Mau.

Based on the literature review, the authors proposed six hypotheses on the determinants of the amount of trade credit granted to shrimp farmers. Data collected from 120 shrimp farmers in Ca Mau were used to test the proposed hypotheses.

Two out of six determinants, i.e. the size of input order (a pulling factor) and the competition among input suppliers (a pushing factor), are significantly positively associated with the amount of trade credit granted to shrimp farmers. No impact of the other determinants was found. The findings imply that shrimp farmers should join cooperatives to enhance access to trade credit and mitigate the risk for input suppliers.

This paper sheds light on the fact that trade credit is still granted to such risky buyers as shrimp farmers, which has not been explored by previous studies.

Drought and salinity intrusion aggravated by climate change threaten agricultural livelihoods in Viet Nan's Mekong Delta. In response, authorities have built water management infrastructure for irrigation and salinity protection. This study assessed the impact of one such project, the Ba Lai dam in Ben Tre province, on the livelihoods of aquaculture farmers.

This study uses the Sustainable Livelihoods Framework to assess the impact of the Ba Lai dam on the livelihood capitals of 18 farming households in four communes, located both upstream and downstream of the dam.

The authors find that, apart from some positive effects, the dam has also brought negative environmental consequences, such as increased water pollution. The authors also find that farmers have responded to the changes by adapting their livelihood practices.

The samples were relatively small, encompassing four communes in Ben Tre province. On the other hand, this case study is instructive to the many ongoing infrastructure projects in the Vietnamese Mekong Delta.

The project have caused an increase in water-related social conflict.

The case of the Ba Lai dam provides a cautionary example for infrastructure-based water management plans, both in Viet Nam and more broadly. The study suggests the need to strengthen community participation and prioritize impacts of farmers' capital assets when constructing water management infrastructure for climate change adaptation.

This study explores the integration of smallholder farmers into the export market in Vietnam, an emerging economy. By introducing a prospective framework, we seek to provide insight into factors that influence this integration process.

This study examines the expected growth and entry of Vietnamese smallholder farmers into high-value export markets. We collected information from 200 independent farmers as well as from five local extension workers, who provided information on 50 farmers.

The study reveals that the adoption of new business models is more influential than the variables traditionally included in models of export-market integration in predicting expected growth and entry into high-value export markets. In addition, the results highlight divergent views between farmers and extension workers regarding the role of collectors, with farmers perceiving collectors as potential partners, while extension workers see them as impediments to growth.

The prospective model presented in this study highlights the importance of policy interventions aimed at promoting new business models and addressing infrastructure and capital constraints for the sustainable transformation of agricultural sectors in emerging markets.

This is one of the first articles to apply a prospective approach to export-market integration and demonstrate its efficacy through an empirical study. The suggested prospective approach could facilitate the design of policies aimed at export-market integration within the context of dynamic, emerging markets.

Thailand’s recent export performance in the EU market for frozen shrimps has improved markedly. Constant market share analysis reveals this improvement to be predominantly the result of competitive advantages in production and marketing. Thailand is able to produce shrimps of high and consistent quality at low costs, under conditions which meet the hygiene and safety standards set by the EU. In addition to competitive advantages, Thailand has benefited from growth in the overall size of the EU export market for frozen shrimps, but has suffered from having only relatively small shares in the important markets of some member States. Market research on consumers’ tastes and preferences could further improve Thailand’s recent export performance.

The purpose of this paper is to investigate and evaluate the new performance measurement model for the Thai frozen shrimp chain.

The performance measurement model was developed by the combination method between a structural equation modeling and an analytical hierarchy process, which the method confirmed and proved the construction of the framework and identified the important key performance indicators of the chain from different supply chain members’ point of views.

The results showed that the model is reliable and valid as well as being theoretically acceptable on the basis of performance measurement foundations. Furthermore, the financial and the customer perspectives are demonstrated as the first to be prioritized in order to evaluate the performance.

Two limitations should be considered. First, small sample size of this study is a limitation. Hence, further study should consider on enough sample size. A next limitation, different points of view from participants has effect on factor loading which represented minus value on the research model. Therefore, the future research should apply several techniques, such as the fuzzy set and data envelopment analysis.

The contribution of this study is the new performance measurement model which based on the integrated conceptual ideas and the synthesizing methods for evaluating the Thai frozen shrimp chain.

The purpose of this paper is to analyze the value chain activities of shrimp firms in Bangladesh, and mapping the Porter’s (1985) value chain framework to see if it works or not. The present study identifies the gap, synthesizes and analyzes those gaps which lead the firms to create more values from firms to consumers.

Interviews were conducted with the shrimp industry managers in the southern region of Bangladesh. Exploratory qualitative research method was used and the questionnaire was semi-structured. Data were gathered from 43 firm managers. After sending multiple phone calls and face to face meeting, the response rate was 35.83 percentages.

Poor transportation, communication gap between the stakeholders, shortage of raw shrimps and lack of quality standard were the areas where shrimp industries were suffering. It was found that some of the primary and secondary activities of shrimp industries did not map with Porter’s framework. Based on Porter’s framework, the study suggested that analyzing and synthesizing those gaps can lead the firm more value and competitive advantages.

Limitations include a lack of knowledge on value chain and shortages of raw materials for the processing plants. Moreover, the sample size was small for this exploratory study.

Shrimp industries will learn standard value chain activities, and identify the gaps based on the mapping of Porter’s value chain.

Using Porter’s value chain this is the first empirical study in the shrimp firms in Bangladesh. The primary research contribution is the revised theoretical framework which can be used for further research on shrimp industries in Bangladesh.

Purpose – This chapter responds to the re-centering of agriculture and food in official forums and public discourse in the current crisis context.

Design – It re-examines the assumptions of the agrarian question through the lens of food regime analysis.

Findings – By examining these developments, particularly the recommendations of the IAASTD report, it is clear there is growing interest in the multifunctional conception of farming that is attentive to ecological and social sustainability.

Research implications – This rethinking is symptomatic of a transformation of the agrarian question: moving away from a concern with the political trajectory of capital in agriculture and the process of depeasantization, towards a concern with ‘peasant’ renewal. This registers an ontological shift towards an agro-ecological paradigm in which an ecologically driven conception of ‘value’ addressing social reproduction rather than capital accumulation is emerging.

Practical implications – New research on “repeasantization” undergirds this claim, and complements the global mobilization of small farmers around the project of food sovereignty. Practically, food sovereignty projects mean growing land rights claims and adoption of diverse forms of biological (rather than chemical) farming.

Social implications – This implies stabilizing rural populations and the possibility of health food and environments.

Value – Intellectually, such developments call for an analytical shift (in food regime and other analyses) towards values other than those of price and productivism in assessing the contribution of agriculture to human survival in a climate-challenged future.
