Global value chains for commodity agriculture have been the target of a broad array of sustainability governance efforts led by both public and private actors. In this paper, we ask: how do public policies and private standards interact in commodity‐exporting countries? To answer this question, we examine the interactions between voluntary sustainability standards and domestic public policies in three cases: soybean farming in Brazil, palm oil production in Indonesia, and pangasius aquaculture in Vietnam. We find that in each case, public and private governance interactions go through a period of competition before ending in a state of reluctant complementarity. We argue that this reluctant complementarity results from the need of governments in commodity‐producing countries to maintain export markets for their goods. This finding challenges the idea that complementarity between public and private sustainable commodity governance is driven by goal alignment and tempers expectations that standards and certifications can mitigate deforestation.

Wolbachia is a ubiquitous endosymbiotic bacterium that manipulates insect reproduction. A notable feature of Wolbachia is male killing (MK), whereby sons of infected females are killed during development; however, the evolutionary processes by which Wolbachia acquired the MK ability remain unclear. The tea tortrix moth Homona magnanima (Tortricidae) harbours three non‐MK Wolbachia strains (wHm‐a, wHm‐b and wHm‐c) and an MK strain wHm‐t. Although wHm‐t and wHm‐c are closely related, only wHm‐t has an MK‐associated prophage region. To understand the evolutionary processes underlying the emergence of MK wHm‐t, we examined Wolbachia infections and phenotypes in 62 tortricid species collected from 39 localities across Japan, Taiwan, Vietnam and Indonesia. PCR assays detected wHm‐c relatives in 51 species and triple infection of wHm‐a, wHm‐b and wHm‐c in 31 species. Apart from Taiwanese H. magnanima, no species exhibited the MK phenotype and were positive for the wHm‐t‐specific prophage. While wHm‐t infection was dominant in Taiwanese H. magnanima, wHm‐a, wHm‐b and wHm‐c were dominant in Japanese H. magnanima populations. These results suggest that wHm‐a, wHm‐b and wHm‐c strains descended from a common ancestor with repeated infection loss and that wHm‐t evolved from the wHm‐c acquiring MK ability in allopatric populations of H. magnanima.

The complementary feeding period is a critical stage of child development when micronutrient needs are high and challenging to meet. Understanding if specific micronutrient gaps exist during this period is critical for effective programming. A Comprehensive Nutrient Gap Assessment (CONGA) was conducted in seven countries in Southeast Asia to estimate gaps in micronutrients commonly lacking in the diets of children aged 6–23 months and to establish the certainty of available evidence for each identified gap. Sixty‐eight evidence sources were identified during this analysis, and 310 micronutrient‐specific data points were identified across all seven countries. Data points varied in recency, representativeness and evidence type. The CONGA methodology enabled the estimation of a gap burden rating for each micronutrient in each country, as well as a rating of their evidence certainty. Micronutrient gaps were identified in vitamin D, zinc and iron and a potential gap was identified in calcium during the complementary feeding period in the region. Evidence relevant to intake and deficiency of folate, vitamin B12, thiamine, niacin, vitamin C and vitamin B6 was limited across the region. Proven strategies to address these gaps include increasing the availability and consumption of nutrient‐dense foods, micronutrient supplementation, large‐scale fortification of staple foods and condiments and point‐of‐use fortification through multiple micronutrient powders and fortified speciality foods. More recent data on micronutrient availability, intake and deficiency is urgently needed in Southeast Asia. Key messages: Older infants and young children aged 6–23 months experience micronutrient gaps during the complementary feeding period in Southeast Asia. Synthesis of evidence compiled across seven countries in the region identified gaps in vitamin D, zinc and iron and a potential gap in calcium during this critical period.National nutrition policies and programmes should consider multiple strategies to address these micronutrient gaps.Over half of the data points relevant to nutrient deficiency and intake compiled from the seven countries are over a decade old. More recent data on micronutrient availability, intake and deficiency is urgently needed in Southeast Asia. [ABSTRACT FROM AUTHOR]

In Southeast Asia, the increasing availability of commercially produced complementary foods (CPCF), including dry or instant cereals (CPCF cereals), has been noted, however, concerns exist around their nutrient profile and labelling practices. This 2021 study assessed the nutrient composition, labelling practices, and micronutrient content of CPCF cereals sold in the capital cities of seven Southeast Asian countries: Phnom Penh (Cambodia), Jakarta (Indonesia), Manila (Philippines), Bangkok (Thailand), Vientiane (Lao PDR), Hanoi (Vietnam), and Kuala Lumpur (Malaysia). The study adapted a nutrient profiling model from the WHO Regional Office for Europe to determine the proportion of products suitable for promotion for older infants and young children. Micronutrient content of fortified CPCF cereals was assessed against fortification levels specified in the Codex Alimentarius guideline for formulated complementary foods. Of the 484 products assessed, 184 (38.0%) met all nutrient composition requirements. Around one‐third of CPCF cereals contained added sugars and/or sweeteners (37.2%) and high levels of sodium (28.9%). None of the CPCF cereals met all labelling requirements, primarily due to the presence of inappropriate claims on the labels. Most fortified CPCF cereals contained adequate amounts of critical micronutrients, such as calcium, iron, zinc, vitamin A, and vitamin D. However, rates of fortification varied across the seven countries, and almost a third (30.8%) of CPCF cereals were not fortified with any micronutrients. To support the appropriate promotion of CPCF in the region, Southeast Asian countries need to strengthen and enforce national binding legal measures, including national standards for the composition, labelling, and fortification of CPCF cereals. Key messages: Despite most commercially produced complementary foods (CPCF) cereals available in Southeast Asia met the majority of nutrient composition requirements, a considerable number of products contained added sugars/sweeteners (37.2%) and high levels of sodium (28.9%). Regulations that prohibit the use of added sugars/sweeteners and establish an upper limit for sodium in CPCF cereals are a policy priority in the region.None of the 484 CPCF cereals studied met all labelling requirements. Inappropriate claims were the most common. Three‐quarters of the products failed to meet labelling requirements on the protection and promotion of breastfeeding. National regulations on labelling must be strengthened and enforced to protect against inappropriate marketing of CPCF.Approximately two‐thirds or more of fortified CPCF cereals contained adequate amounts of micronutrients critical for older infants and young children (IYC), such as calcium, iron, zinc, vitamin A and vitamin D. Nonetheless, the fortification of CPCF cereals varied greatly by country, and almost a third (30.8%) of CPCF cereals were not fortified with any micronutrients. This is a missed opportunity to provide essential micronutrients to older IYC in contexts where nutrient‐poor diets are common. Future policies that stipulate mandatory minimum micronutrient levels for CPCF cereals are recommended for the region. [ABSTRACT FROM AUTHOR]

Stakeholders in global value chains (GVCs) commonly argue that factory managers will choose humane working conditions if they can be persuaded that social compliance improves firm performance. Yet, despite evidence that humane conditions increase productivity, product quality and on‐time delivery, inhumane conditions in GVCs persist. Evidence from a sample of factories in the Better Work programme in Indonesia, Jordan and Viet Nam indicates that achieving social compliance may be costly, offsetting productivity benefits. A positive impact on profits depends on international buyer sourcing practices, including higher output prices. The COVID‐19 pandemic has confirmed the key role played by buyers in determining working conditions. [ABSTRACT FROM AUTHOR]
