Abstract: 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.

Abstract: 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.

Abstract: Traditional lifestyles of lowland rice farmers of the southern provinces of Lao People’s Democratic Republic are rapidly changing, due to two important trends. Firstly, there is a push towards modernization and commercialization of farming. Secondly, though farmers still focus on rice farming as a key activity, there is an increasing move towards ersification of livelihoods. The changes have seen the uptake of non-rice crops, livestock husbandry and forest and river utilization as well as non-farming activities. This has influenced gender relations, impacting household agricultural production decisions and lified transitional trends. To explore the processes, we analyzed data from a study of innovation adoption amongst rice farmers in southern Lao PDR. The study revealed nuances of gender-based differences in the priorities and attitudes towards farming and off-farm activities, as well as differences in behaviour related to the adoption of new practices. Women were more focused on non-farming practices and considered engaging in the modern, non-traditional, economy more so than men. Women also reported experiencing greater challenges when engaging and trading in the agricultural marketplace. The study supports the importance of taking a gendered approach to understanding the inherent complexities within agrarian change.

Abstract: 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 ersification of the existing value chains in order to reduce the impacts of price fluctuations that are associated with limited global commodity chains.

Abstract: What influences farmers’ decisions to adopt agricultural technologies is an important question for international agricultural research projects. There are often interpersonal differences between women and men that influence the adoption of decisions and behaviours, but few studies in the literature focus on these factors. We describe a game-based approach to explore decision-making processes underpinning the adoption of new farming technologies and practices in Lao People’s Democratic Republic. Sowing a different rice variety is the tailored technology. The game explored adoption behaviours influencing decisions on transitioning from growing glutinous rice, a traditional variety preferred for consumption, to “white” rice for commercial export to international markets. We conducted separate game-workshops with 36 women and 36 men in 4 villages of southern Laos that were transitioning from subsistence to commercial smallholder production. The gaming exposed various possible behaviours and decisions that women and men considered. Access to resources, both assets and information, was equal for all players, yet women were found to adopt new rice varieties more readily than men and to engage in cooperative behaviours in the game situation. The study highlighted the need for further gender-sensitive research into cooperation among women in the agricultural context—an understanding beneficial for countries and regions undergoing agricultural transition.

Abstract: A tax on sugar-sweetened beverages (SSB) has been proposed to address population weight gain but the effect across socio-economic position (SEP) is unclear. The current study aimed to clarify the differential impact(s) of SSB taxes on beverage purchases and consumption, weight outcomes and the amount paid in SSB taxes according to SEP. Databases (OVID and EMBASE) and grey literature were systematically searched in June 2015 to identify studies that examined effects of an SSB price increase on beverage purchases or consumption, weight outcomes or the amount paid in tax across SEP, within high-income countries. Of the eleven included articles, three study types were identified: (i) those that examined the association between variation in SSB taxes and SSB consumption and/or body weight ( n 3) (ii) price elasticity estimation of SSB demand ( n 1) and (iii) modelling of hypothetical SSB taxes by combining price elasticity estimates with population SEP-specific beverage consumption, energy intake or body weight ( n 7). Few studies statistically tested differences in outcomes between SEP groups. Nevertheless, of the seven studies that reported on changes in weight outcomes for the total population following an increase in SSB price, all reported either similar reductions in weight across SEP groups or greater reductions for lower compared with higher SEP groups. All studies that examined the average household amount paid in tax ( n 5) reported that an SSB tax would be regressive, but with small differences between higher- and lower-income households (0·10–1·0 % and 0·03 %–0·60 % of annual household income paid in SSB tax for low- and high-income households, respectively). Based on the available evidence, a tax on SSB will deliver similar population weight benefits across socio-economic strata or greater benefits for lower SEP groups. An SSB tax is shown to be consistently financially regressive, but to a small degree.

Abstract: Efforts to achieve inclusive and sustainable agricultural-sector growth in developing economies will benefit from agricultural entrepreneurship (agripreneurship) by young farmers. However, challenges that hinder transition from subsistence to commercial agriculture remain. A better understanding of enablers and constraints that young farmers experience can facilitate the development of an enabling environment for sustainably transitioning from subsistence into commercial agriculture. We interviewed 74 young agricultural entrepreneurs (agripreneurs) in Laos, a country with a young and highly rural population, to explore their perceptions of institutions and support functions that enable or limit agripreneurship. Respondents reported that institutions and support functions have generally improved to make agripreneurship easier than before, with infrastructure, logistics, and new platforms for information sharing, banking, marketing, and delivery identified as specific improvements. However, agripreneurs identified weaknesses in the nature, scope, and quality of agricultural information and extension services that limit their performance difficulties in accessing loans with favorable conditions, which discourages investment opaque and costly payments and red tape processes that frustrate business establishment, operations, and regulatory compliance and a lack of targeted policy actions towards enabling youth agripreneurship, which leaves youth feeling unsupported. Improvements in infrastructure, promotion of agri-careers, and more transparency of taxation, registration, and administration fees/systems are recommended.

Abstract: 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.
