The purpose of this chapter is to illustrate the contribution made by migrants in the territory that hosts them, particularly when they transfer their knowledge to members of the community. In the specific case of the sea urchin fishery, it is described how the Morishita family in Baja California undertakes the sea urchin value chain, from the location of population banks to the commercialization of the product in the Japanese market and, by therefore, the promotion of development in rural places while starting a culture of export and currency generation. An adventure of opportunities that has been successful for more than 50 years, whose origin is the sustainable use of “a plague” that today is a delicacy for many.

The aim of the paper is to shed light on the use of chitosans and chitooligosaccharides as biopreservatives in various foods animal. Foods of animal and aquatic origin (milk, meat, fish, eggs, sea foods, etc) become contaminated with a wide range of microorganisms (bacteria, molds and yeasts) during harvesting, transporting, processing, handling and storage operations. Due to the perishable nature of these foods, their preservation is of utmost importance. Though many synthetic chemicals are available, yet their use is quite restricted due to their hazardous effects on human health.

Within the domain of food industry, traditionally chitosan is used for biopreservation of foods, which is well known for its nutritional and medicinal properties in human nutrition. However, chitooligosaccharides also possess a number of nutraceutical and health promoting properties in addition to their preservative effect and shelf-life extension of foods. In this study, the comparative effects of both chitosan and chitooligosaccharides on preservation of foods of animal and aquatic origin have been summarized.

Though chitosan has been extensively studied in various foods, yet the use of chitooligosaccharides has been relatively less explored. Chitooligosaccharides are bioactive molecules generated from chitosan and have several advantages over the traditional use of chitosan both in food products and on human health. But unfortunately, little or no literature is available on the use of chitooligosaccharides for preservation of some of the foods of animal origin. Notable examples in this category include cheese, beef, pork, chicken, fish, sea foods, etc.

This paper focuses on the effects of chitosans and chitooligosaccharides on the processing and storage quality of foods of animal and aquatic origin, which offers a promising future for the development of functional foods.

This paper seeks to problematise “accounting for biodiversity” and to provide a framework for analysing and understanding the role of accounting in preserving and enhancing biodiversity on Planet Earth. The paper aims to raise awareness of the urgent need to address biodiversity loss and extinction and the need for corporations to discharge accountability for their part in the current biodiversity crisis by accounting for their biodiversity‐related strategies and policies. Such accounting is, it is believed, emancipatory and leads to engendering change in corporate behaviour and attitudes.

The authors reviewed the literature relating to biodiversity across a wide array of disciplines including anthropology, biodiversity, ecology, finance, philosophy, and of course, accounting, in order to build an image of the current state of biodiversity and the role which accounting can and “should” play in the future of biodiversity.

It is found that the problems underlying accounting for biodiversity fall into four broad categories: philosophical and scientific problems, accountability problems, technical accounting problems, and problems of accounting practice.

Through establishing a framework problematising biodiversity, a roadmap is laid out for researchers and practitioners to navigate a route for future research and policymaking in biodiversity accounting. It is concluded that an interdisciplinary approach to accounting for biodiversity is crucial to ensuring effective action on biodiversity and for accounting for biodiversity to achieve its emancipatory potential.

Although there is a wealth of sustainability reporting research, there is hardly any work exploring the role of accounting in preserving and enhancing biodiversity. There is no research exploring the current state of accounting for biodiversity. This paper summarises the current state of biodiversity using an interdisciplinary approach and introduces a series of papers devoted to the role of accounting in biodiversity accepted for this AAAJ special issue. The paper also provides a framework identifying the diverse problems associated with accounting for biodiversity.

This paper aims, using a case study-based research approach, to investigate the role of climate and non-climate drivers in shaping three commercial marine sectors: fishing, aquaculture and marine tourism. Essential elements of climate change research include taking a whole of systems approach, which entails a socio-ecological perspective, and considering climate challenges alongside other challenges faced by resource users.

The analysis is based on information gained using in-depth semi-structured interviews in a coastal community in southeast Australia. Even though climate drivers differ, the economic sectors of this community are representative of many similar coastal communities around Australia.

Results show that at a community level, people involved in, or associated with, marine sectors are aware of climate change impacts on the marine environment. Even though many may not see it as a pressing issue, the potential effect of climate change on business profitability was recognised. Both the profitability of commercial fishing and aquaculture (oysters) was affected through mostly a downward pressure on product price, while marine tourism profitability was mainly affected through changes in the number of visitors.

A case study approach is inherently case study-specific – although generalities from complex system representation, built on local survey respondent observation and knowledge of the combined and linked physical–biological-, social-, economic- and governance drivers. This study shows the importance of a holistic approach; yet, researchers must also consider all community sectors and cross-regional investigations to avoid future resource conflicts.

A number of positive impacts from climate-driven change, mainly from windfall economic benefits of geographically relocated species, were reported for commercial- and charter fishing. However, no positive impacts were reported for the aquaculture- and dive sector. In the aquaculture sector, climate drivers were of great significance in industry participation, while participation in commercial fishing was mainly driven by socio-economic factors.

To ensure the combined marine sectors retain a viable component of coastal communities’ economic focus, there is a need to understand what drives participation in the marine sector, and what the role of climate change is in this. To fully understand the ramifications of climate change in the marine environment, it is essential to understand its impacts across all marine sectors.

Combining the different domains with climate drivers allows for identification and assessment of targeted adaptation needs and opportunities and sets up a comprehensive approach to determine future adaptation pathways.

Landscapes bear potential as heritage resources, unifying natural and cultural history that can be experienced today in special preserved areas. The paper aims to discuss these issues.

Geoarchaeological investigation 2006-2011 explored this potential at the Ritidian Unit of Guam National Wildlife Refuge.

As experienced today, the Ritidian landscape heritage embodies the complex outcomes of a 3,500-year record of ecology and evolution.

A long-term perspective of unified natural-cultural history will increase scientific accuracy and enhance visitor experience of landscapes of heritage resources.

Sustainable development of landscape heritage can occur most successfully in cases of thorough research in areas of protected and managed ecosystems with reasonable public access.

The detailed results in this case may serve as a model example for other studies and programmes developing landscapes as heritage resources.
