Profiling, monitoring and conserving caterpillar fungus in the Himalayan region using anchored hybrid enrichment markers.

The collection of caterpillar fungus accounts for 50-70% of the household income of thousands of Himalayan communities and has an estimated market value of $5-11 billion across Asia. However, Himalayan collectors are at multiple economic disadvantages compared with collectors on the Tibetan Plateau because their product is not legally recognized. Using a customized hybrid-enrichment probe set and market-grade caterpillar fungus (with samples up to 30 years old) from 94 production zones across Asia, we uncovered clear geography-based signatures of historical dispersal and significant isolation-by-distance among caterpillar fungus hosts. This high-throughput approach can readily distinguish samples from major production zones with definitive geographical resolution, especially for samples from the Himalayan region that form monophyletic clades in our analysis. Based on these results, we propose a two-step procedure to help local communities authenticate their produce and improve this multi-national trade-route without creating opportunities for illegal exports and other forms of economic exploitation. We argue that policymakers and conservation practitioners must encourage the fair trade of caterpillar fungus in addition to sustainable harvesting to support a trans-boundary conservation effort that is much needed for this natural commodity in the Himalayan region.

Drivers of Food Choice among Children and Caregivers in Post-earthquake Nepal.

Food systems in many countries are experiencing a shift from traditional foods toward processed foods high in sugar, fat and salt, but low in dietary fiber and micronutrients. There is an urgent need to better understand drivers of changing food behavior, particularly for lower-income countries. This study analyzes drivers of food choice among children and parents in rural Nepal. It uses qualitative data collected through key informant interviews and focus group discussions with school children, parents and teachers. The study reveals substantial changes in food behavior during the past decade with increased consumption of rice, meat, and highly processed snack foods while an increased consumption of fruit and vegetables is not evident. It identifies cash availability is the main driver of increased rice, meat and snack food consumption. The second driver is the 2015 Nepal earthquake, which accelerated the transition from homegrown food to purchased food as people got habituated to eating more meat and snack foods while reconstruction tripled local wages and changed the food environment. This shows how humanitarian assistance in the wake of extreme shocks can unintentionally contribute to unhealthy eating habits. An integrated school and home garden intervention appears to contribute to healthier diets.

Nudging children toward healthier food choices: An experiment combining school and home gardens.

School gardens have become a widely used approach to influence children's food knowledge, preferences and choices in low- and high-income countries alike. However, evidence indicates that such programs are more effective at influencing food knowledge and preferences than actual food choices. Such finding may occur because school gardens insufficiently influence the food behavior of parents and because healthy food items are not always available in children's homes. We tested this hypothesis using a one-year cluster randomized controlled trial in Nepal with 15 treatment and 15 control schools and a matched sample of 779 schoolchildren (aged 8-12) and their caregivers. Data were collected before and after the intervention during the 2018-2019 school year. In addition, children's food consumption was monitored using a monthly food logbook. Average treatment effects were quantified with a double-difference estimator. For caregivers, the intervention led to a 26% increase in their food and nutrition knowledge (p < 0.001), a 5% increase in their agricultural knowledge (p = 0.022), a 10% increase in their liking for vegetables (p < 0.001), and a 15% increase in home garden productivity (p = 0.073). For children, the intervention had no discernible effect on food and nutrition knowledge (p = 0.666) but led to a 6% increase in their liking for vegetables (p = 0.070), healthy food practices (p < 0.001), and vegetable consumption (October-December +15%; p = 0.084; January-March +26%; p = 0.017; April-June +26%; p = 0.088). The results therefore indicate both schools and parents matter for nudging children toward healthier food choices.

Mapping national REDD+ initiatives in the Asia-Pacific region.

Countries in the Asia-Pacific region are pioneers in the implementation of climate change mitigation initiatives. They have implemented readiness activities to fulfil the requirements for results-based payments from the forestry sector (termed REDD+). Using content analysis, a questionnaire, and a series of workshops with key stakeholders, we mapped the REDD + readiness of 11 Asia-Pacific countries with respect to UNFCCC's resolutions on REDD+. Their status was mapped against the Nationally Determined Contribution (NDC), which constitutes the five design elements of the Warsaw REDD + Framework and the Forest Carbon Partnership Facility (FCPF) requirements. While the overall achievements vary across the studied countries, our results demonstrate that Vietnam, Nepal, and Indonesia are in an advanced stage of REDD + readiness. A significant number of conditional NDCs and timely and adequate technical and financial support are imperative for the studied countries to achieve a high level of readiness. However, lack of trust and coordination among the state and non-state actors, limited national participation of Civil Society Organizations and Indigenous Peoples in REDD + related committees, and conflicts among regulatory frameworks related to forestry and other land uses remain common challenges for these countries. These challenges risk disrupting the essence of REDD + as a multi-level, multi-stage and multi-stakeholder governance system. Stakeholders in these countries are optimistic about a better performance of REDD + regarding emission reduction, enhanced livelihoods, improved forest governance and improvement in biodiversity. However, any optimism is challenged by stakeholder's own suspicion of the effectiveness of REDD + projects to achieve permanency and control leakage/displacement. Building political will and the development of context-specific benefit-sharing plans and their effective implementation could be important keys to maintaining optimism of stakeholders about REDD + initiatives.
