The development of the Amazon region depends on the organisation and improvement of production chains able to benefit forest species and animals. The purpose of this paper is to map and categorise the studies developed on the Arapaima gigas, a commercialisable fish native to the Amazon, responding to the following research questions: first, which links of the production chain have most of the studies on the pisciculture of the Amazon region? Second, is environmental performance being approached in studies on production chains in the Amazon region? To reach the objective, the authors used the systematic literature review (SLR) method. The authors analysed a sample of 121 articles published in 95 journals between 1981 and 2018. The research contains bibliometric and contents analyses. The main conclusions include the identification of various possibilities of studies throughout the different production chains in the Amazon region; the multidisciplinarity of research on a single species in the Amazon region; the importance of empirical studies in the construction of knowledge about the natural behaviour of the species; the need for integration and sharing of knowledge to create an efficient and competitive production chain. As a limitation, this study encompasses a broad spectrum of issues in the literature, therefore, it was only possible to offer a general overview of these issues. At the same time, this broad and intentional approach presents a comprehensive framing of the themes and phenomena that occur at each link of the production chain of Amazon fish farming.

This research consists in an SLR with organised, transparent and replicable procedures as recommended in the literature (Littell et al., 2008). The SLR is suited to the mapping of areas where there is a high level of uncertainty and new studies are necessary (Petticrew and Roberts, 2006). This research method is especially useful when dealing with a large volume of information (Tranfield et al., 2003). The use of SLR limits researcher bias by trying to evaluate and select relevant studies on the study theme (Petticrew and Roberts, 2006).

There are a number of possibilities for studies of the different production chains in the Amazon region; the results of mapping the production chains help to prioritise “what” should be researched in the Amazon region to promote more effective impacts for all stakeholders; research on pisciculture in the Amazon region can be used as a diagnostic tool for public policy formulators; the development of corporate environmental management is intrinsically linked to the process of analysis and understanding of the operations and costs that arise in different links of the production chain.

As a limitation, this study encompasses a broad spectrum of issues in the literature, therefore, it was only possible to offer a general overview of these issues.

In terms of practical implications, it is possible to note that the dispersion of themes found in this study confirms the plurality of the richness of the Amazon and suggests that research institutions should be able to commit to the drafting of integrated planning of science, as well as compilation of the results reached. It is also important to highlight Brazil’s role in the leadership of research in the Amazon region compared to other countries.

The aim of the paper was twofold: to supply a focussed review of the literature on the production chain of a species in Amazon pisciculture and to identify a research agenda capable of overcoming the gaps that impede the development of this chain. More specifically, this study reviewed the available research on the chain in question to analyse the links that have the largest volume of studies and to orient future research.

This study aims to present a methodological framework to evaluate the relationship between social network centrality, individual competitiveness and network competitiveness.

Tilapia fish farmers in the Canoas I hydroelectric dam (states of São Paulo and Paraná, Brazil) were provided with a roster of all actors in their network and interviewed to obtain information on relational and competitiveness variables. UCINET was used to calculate the degree centrality of each farmer. Seven competitiveness drivers were combined into a single indicator to determine the level of competitiveness. A four-quadrant matrix was constructed to investigate the relationship between degree centrality and level of competitiveness.

A positive relationship was found between degree centrality and level of competitiveness.

Agents upstream or downstream of fish farming were not interviewed, precluding an in-depth analysis of competitiveness in terms of market structure and market relations. The authors suggest that future studies should investigate the influence of upstream and downstream agents on the social network and competitiveness of fish farmers. It is also important to monitor changes in the level of competitiveness of fish farmers in the event of a national economic crisis.

Development of a novel methodological framework on the basis of two methodologies, social network analysis and competitiveness analysis.

In line with climate variability such as extreme floods and cyclones, siltation is identified as among the most serious environmental problems posed to Chilika Lagoon fisheries. Exposure to silt accumulation reduced the water spread area and hindered the exchange of water between the sea and river, resulted in decreased salinity level and subsequent prolific growth of freshwater invasive species. As a result, fish landing quantities in Chilika Lagoon rapidly decreased until the year 2000, thereby leading to the poorer people not being effectively able to adapt to the ecological-social-economic system. The weed invasion also obstructed passages from boat jetties to fishing grounds, sometimes leading to boat clashes and the subsequent disputes among fishers.

This study aims to investigate the impact of financial inclusion in promoting sustainable livelihood among indigenous women entrepreneurs. Moreover, the study has also examined the mediating role of microentrepreneurship between financial inclusion and sustainable livelihood.

Structure equation modeling has been used to analyze the mediating effect of microentrepreneurship between financial inclusion and sustainable livelihood development. In total, 598 samples of indigenous women across the Sundargarh and Mayurbhanj districts in Odisha are used for the statistical data analysis in the study.

The results showed that financial inclusion has direct and indirect effect on promoting sustainable livelihood among indigenous women. The results also highlighted that microentrepreneurship significantly mediates the relationship between financial inclusion and sustainable livelihood.

The Government of India should formulate policies on financial inclusion by reviewing the findings of this study. In addition, to increase the base of microenterprises and the achievement of sustainable livelihood in rural regions, more focus should be given toward the promotion of inclusive finance among indigenous women in India.

The present idea has not been discussed or explored earlier among the indigenous communities in the Indian context. So, the study will benefit the marginalized groups of women in promoting their livelihood sustainably.

In this research, the authors apply artificial neural networks (ANNs) to uncover non-linear relationships among factors that influence the productivity of ragpickers in the Indian context.

A broad long-term action research program provides a means to shape the research question and posit relevant factors, whereas ANNs capture the true underlying non-linear relationships. ANN models the relationships between four independent variables and three forms of waste value chains without assuming any distributional forms. The authors apply bootstrapping in conjunction with ANNs.

The authors identify four elements that influence ragpickers’ productivity: receptiveness to non-governmental organizations, literacy, the deployment of proper equipment/technology and group size.

This study provides a unique way to analyze bottom of the pyramid (BoP) operations via ANNs.

This study provides a road map to help ragpickers in India raise incomes while simultaneously improving recycling rates.

This research is grounded in the stakeholder resource-based view and the network–individual–resource model. It generalizes these theories to the informal waste value chain at BoP communities.

A number of large banks were nationalised in India in 1969 with a view to making banking services available all over India in unbanked and under‐banked areas, and to protecting the rural population and poor people from the clutches of money lenders by making credit available at subsidised rates. Indian banks have achieved this to a considerable extent but they must expand their services in the marketing and technical advice fields in order to gain the people's confidence in their financial skills.

A HUNDRED YEARS AGO, while his country was in the throes of civil war, a wealthy American, Elihu Burritt, was walking through Scotland notebook in hand. He was in the final stages of a walk from London to John o' Groats, and his role was that of corresponding secretary (unpaid) to a farmers’ club he had founded in his native town of New London, Connecticut.

Traces the diffusion of palm oil by a joint venture company in Indonesia during the early 1980s. The diffusion framework provided by E.M. Rogers is examined in this context. The author relates his personal observations over the course of two years and arrives at certain conclusions. In keeping with Rogers′ framework, characteristics of the innovation and change agent effort were critical in the diffusion. However, Rogers′ two‐step model of diffusion was not relevant in this case. A one‐step model of diffusion is recommended for the marketing of industrial products where knowledge of the innovation is considered to be proprietary information and is not spread through interpersonal networks.

This profile is somewhat more exotic than the usual ones found in this, hopefully, august journal and your reporter would like to dwell on the background more than is usual. If you take your world atlas, you may find Ipoh as an isolated dot in the middle of the Malaysian peninsula, a little to the north‐west of Kuala Lumpur. Viewed thus, why would Multicore Solders choose such an isolated outpost to establish a subsidiary factory? Arriving at the international airport at Kuala Lumpur starts to give one a clue: there are enormous bare scars in the plain. Flying from Kuala Lumpur to Ipoh, these scars multiply. They are the remains of the open‐cast tin mines in the alluvial deposits. Viewed from the air, they are a terrible blot on the landscape. The amazing thing is that they juxtapose oil palm, fruit and rubber plantations and even untouched jungle, but they remain bare and desert for decades. It is evident that no effort has been made to conserve the vegetable soil and replace it after the mining operations are finished, but this may be because the humus layer is so thin that it would be impossible to do so. To the ignorant European that this writer is, I imagined that the jungle was an all‐invading vegetation ready to swallow‐up every square metre of land: not so, it is a very precarious ecosystem where the humus formed by the rotting vegetation is swallowed up by the new growth faster than it can form. The jungle soil is very thin, bare rock being common and such a humus layer may take decades or even centuries to form. Most of the disused tin‐mines are therefore as devoid of life as the starkest desert. It would seem that, after fifty years or so, the first signs of vegetation start to reappear, a very meagre growth which, in time, may develop into scrub or secondary jungle without high trees.
