Seaweed farming in Indonesia is carried out throughout much of the archipelago and is mainly undertaken by smallholder farmers. Indonesia is the largest global producer of the red seaweeds Kappaphycus and Eucheuma, which are used to produce carrageenan, and is a major producer of Gracilaria, which is used to produce agar. Seaweed farming is attractive to farmers in rural coastal communities because capital and operating costs are low, farming techniques are not technically demanding, labour requirements are relatively low (allowing farmers to engage in other livelihoods), and production cycles are short (30–45 days), providing regular income. Using reported values for seaweed-farming income, we conclude that seaweed farming can, but does not always, lift rural households above the Indonesian poverty line. In addition to direct financial benefits, seaweed farming also contributes to human and social capital within seaweed farming households and communities. Achieving continued economic and social benefits from seaweed farming will require additional policy development, as well as research and development to support improved and more consistent seaweed productivity and improved product quality at the farm level, provision of effective extension and technical support services, and diversification of the existing value chains in order to reduce the impacts of price fluctuations that are associated with limited global commodity chains.

Prior research has identified both the contribution that people make to nature and the contribution that nature makes to people (by enhancing wellbeing) - with clear conceptual models to describe the interactions. Prior research has also made a clear case for incorporating insights from multiple perspectives and knowledge systems when seeking to better understand this interactive system. What is lacking, is guidance on how to operationalise some of these ideas to provide bespoke advice to environmental managers. Arguably, we have an adequate, albeit imperfect, understanding of how to operationalise (measure, value and/or otherwise account for) some parts of the conceptual model. There is, for example, abundant literature that describes different ways of valuing Ecosystem services, and a growing body of literature that describes and quantifies the ecological benefits of various stewardship activities, which will subsequently also generate an indirect benefit to people (since improved ecological conditions will improve Ecosystem services). In comparison, we know relatively little about the way in which stewardship activities directly benefit people - and it is on this gap that our paper focuses. We partially fill that knowledge gap by first reaching out to and learning from some of Australia's First Nations People. Key learnings underscore the inter-connectedness of the system, and the need for resource managers to not only monitor the extent and condition of natural system but also the extent and condition of an inextricably connected human system, in addition to the human-nature interactions. We clearly identify ways in which those insights can be used to improve and extend accounting frameworks, such as SEEA Ecosystem Accounts developed by the United Nations that are often used by natural resource managers. In so doing, we generate new insights about Indigenous stewardship (Caring for Country) and methods of accounting for and monitoring stewardship activities. As such, our work provides a practical illustration of one way to populate conceptual models with 'real world' data that also incorporates different world views, to support decision makers for improved social and environmental outcomes.

Conservation and environmental management have been reported as offering opportunities to substantially improve the wellbeing of Indigenous people. Using the holistic wellbeing impact evaluation (W-IE) approach—well suited for use in Indigenous communities—we interviewed 190 Indigenous Australians across four communities. All communities were involved in the Indigenous land and sea management programs (ILSMPs). Our study explored the conceptualisation of ‘wellbeing’ by participants. In particular, we were interested in the aspects of wellbeing perceived to be affected by ILSMPs. Out of the 26 wellbeing factors explored, ‘Health centres’; ‘Language’; ‘Schools’; and ‘Safe community’ emerged as being of highest importance to the largest percentage of the respondents. When grouped using principle components analysis (PCA), the ‘Community and society’ domain emerged as the most important; accounting for 52% of the overall importance of all wellbeing factors. The second most important domain was the ‘Country and culture’, contributing 31%. Lastly, ‘Economic aspects’ contributed only 17%. Respondents believed that ILSMPs have played a considerable causal role in improving wellbeing, by positively changing factors most important to them. Specifically, 73% of perceived causal links were related to improvements in the ‘Country and Culture’ and 23% to ‘Community and Society’ domain. We thus conclude that land management for Indigenous people is much more than ecological or environmental management with ILSMPs, perceived to cause a wide range of cultural and social benefits. We also propose ways in which the future design of such programs could be improved to further increase benefits.

Combining insights from literature on the Theory of Change, Impact Evaluation, and Wellbeing, we develop a novel approach to assessing impacts. Intended beneficiaries identify and rate factors that are important to their wellbeing, their satisfaction with those factors now, and before an intervention. Qualitative responses to questions about perceived changes and causes of change are linked to quantitative data to draw inferences about the existence and/or importance of impact(s). We use data from 67 Ewamian people, in a case study relating to Indigenous land management, to provide proof of concept. ‘Knowing that country is being looked after’ and ‘Having legal right/access to the country’ were identified as important to wellbeing, with perceptions that Native Title determination, declared Indigenous Protected Area and associated land management programs have had a significant and positive impact on them. Further method testing might determine the utility of this approach in a wide range of settings.

Seaweeds are a source of food throughout the Pacific region. Kiribati, however, does not have a strong history of using seaweed in their diets, despite having reliable access to indigenous edible seaweeds. A series of peer-led seaweed training workshops held in Kiribati between 2018 and 2019 provided women with knowledge, skills, and motivational support needed to engage in the seaweed supply chain, from harvesting, processing, and marketing to consumption. This study aimed to identify opportunities and enablers to support women’s participation across the seaweed supply chain. Structured interviews with 49 women explored their interest and expected costs and benefits from involvement in the supply chain. There was high interest in most seaweed-related activities and the key motivators were health and nutrition for themselves and their family. Participants were also interested in developing and sharing new skills and saw the potential for income generation. However, there were also clear barriers including a desire for further training in seaweed harvesting, processing, and recipe creation; additional social support; and in public promotion. Given the natural resources and desire of women to engage in developing this new edible seaweed supply chain in Kiribati, there is now a need for capacity development to build social and economic wellbeing and food security across the broader community. Additional peer-to-peer training opportunities may look to other Pacific Islands where seaweed is already an established and traditional food.

Seaweeds are a traditional food throughout the Pacific. In Samoa, the edible seaweeds limu fuafua (sea grapes, Caulerpa racemosa and C. chemnitzia) and limu a’au (red seaweed, Halymenia durvillei and Halymenia sp.) are hand-harvested and consumed fresh or cooked, respectively. However, there is limited scientific or traditional documentation of these commodities. Here, we assess the traditional use and cultural value of edible seaweeds and explore modern consumer preferences and perceived nutritional benefits. Structured enumerator-administered questionnaires were used to examine the relationship between consumption and demographics and subsequently to assess the key motivators for consumption, including perceived nutritional benefits. A total of 320 participants were surveyed across 20 village communities, with 95% reporting consumption of Caulerpa and 40% of Halymenia. Consumption was primarily on a weekly to monthly basis, and even once a day. Motivators and barriers for consumption were then assessed in 320 village participants with an additional 203 intercept interviews at fish markets. A content analysis of the open-ended questions revealed the key motivators for eating limu were health and taste (positive), whereas the key barriers were taste (negative) and availability. We identify opportunities to develop a nutrient evidence base for Samoan seaweeds to aid in marketing, especially for youth.
