Although the advent of new technologies and online platforms has revolutionized the face of marketing in agriculture sector, little study exists to assess the farmers’ willingness to adopt (WTA) such technologies for their products. Here, we assessed this WTA for a mobile app – the Bamboost for marketing bamboo products and determined the related factors in municipality of Maasin in Iloilo province of Philippines, where 112 farmers were interviewed using the purposive sampling method. Extended Technology Acceptance Model was used to assess the WTA through the analysis of farmers’ perceived usefulness (PU), ease of use (PEOU), innovativeness (PI), social influence (SI), Information Awareness (IA), cost (PC), and socio-demographic factors. We found that PU, PEOU, PI, SI, and farm size had positive correlation and statistically significance at 1% (p <0.001). However, the perceived cost had significant negative influence on farmers’ WTA because of their concerns about the overall cost such as costs for mobile data, transaction, and downloading. To promote the use of the mobile app such as Bamboost to farmers, it is important that government develop enabling policies to reduce the costs of the technology adoption, which could result in rural poverty reduction. Nevertheless, to increase wider adoption beyond the study area, study on farmers’ perceptions at different locations and after the app is introduced can provide the needed information for a better-informed decision making that is beneficial to farmers as well as the technology suppliers.

Calcium deficiency during child growth leads to osteoporosis in later stages of life. Finger millet is one of the calcium dense foods, with three times the level of calcium than milk, and the only cereal that contains high calcium content which is consistent across different varieties (364 ± 58 mg/100 g). Thus, finger millet has potential for addressing calcium deficiency naturally. This study aimed to determine the retention and impact of finger millet calcium on bone turnover through a systematic review and meta-analysis. Three human studies were eligible for systematic review. Of these, only two were eligible for meta-analysis to assess the retention of calcium in children of 9 to 12 years. One study on bone turnover markers was not used in the meta-analysis as at least two studies are required to conduct meta-analysis. Due to the lack of complete data only four studies were eligible for meta-analysis to assess the in vitro bioavailability of calcium from unprocessed and a range of different types of processed finger millet. The result shows that there was significant retention (p< 0.05) of 23.4 ± 2.9% calcium from finger-millet-based diet which could help bone accretion during child growth if finger-millet-based diet is consumed. The bone turnover marker study shows that the resorption of calcium reduced by 28% and 47% among peri and post-menopausal women respectively after feeding the nutria mixed grain ball. However, there is no significant change in bone formation marker. Depending on the type of processing, calcium bioavailability either increased or decreased. One in vitro study showed that calcium bioavailability from finger millet was 28.6% when boiled, whereas three studies on processing show that certain processing can double the calcium bioavailability to 61.4%. Irrespective of the type of processing, finger millets contribute to high calcium retention and extremely high bioavailable calcium and could be useful for healthy growth and in dealing with complications related to calcium deficiency.

Lack of understanding of the ways local subpopulations perceive various changes associated with rapid growth of the tourism industry may lead to unsustainable development. This study assessed the levels and determinants of residents’ perception regarding the changes in environmental, sociocultural, and economic conditions associated with tourism development in Phuket, Thailand. A structured questionnaire survey was conducted with 450 residents covering all three districts of Phuket Province to capture overall indicators and detailed sub-indicators of perception, whilst factors affecting the perceived changes were examined through ordered logistic regression and seemingly unrelated regression (SUR) analyses. The descriptive statistics showed that residents perceived unfavorable changes in various conditions in the island such as increased levels of pollution, road accidents, traffic congestion, and costs of living, while at the same time acknowledging the importance of long-term economic contribution of tourism development. Moreover, regression analyses revealed that various sociodemographic factors such as gender, education, residency duration, and occupation influenced residents’ perception of the changing local conditions. At the sub-indicator level, detailed insights were obtained such as female residents being more likely to positively perceive some of the changes such as increased availability of public space. Implications and suggestions for policy design and planning are discussed in detail.

As of 10 July 2021, there have been over 186 million cases of COVID-19 and more than four million died as a result of this disease. The COVID-19 outbreak has also contributed to tremendous global decline in trade flows. The rapid spread of COVID-19 and the measures implemented by governments to contain the pandemic have had serious consequences for the world's economies. While the pandemic has affected the international movement of people, goods and services, there is still limited systematic research regarding the possible associations between the COVID-19 measures on countries' international trade flows. To fill this gap, we conducted regression analysis based on country level time series data from the United Nations and World Bank datasets. The results of the random effects panel regression models show that, the country import and export values are positively affected by health-related policies, while there is a negative association between stringency measures and import and export values. More specifically, school closing, stay-at-home requirements, and testing policy measures were found to have significant negative effects on countries' trade values. In contrast, facial covering policies were found to have significant positive effects on countries' import, export and total trade values.

This study assessed the livelihood vulnerability of rice farming households in Can Tho, Dong Thap, and Tien Giang provinces in the Mekong delta region (MDR) of Vietnam using primary data collected from 405 rice farmers, and the Livelihood Vulnerability Index (LVI) and LVI-Intergovernmental Panel on Climate Change (LVI-IPCC) approaches. The calculated LVI revealed that rice farming households were vulnerable in terms of the social network, livelihood strategies, natural disaster and climate variability, and food security. The LVI-IPCC revealed that Tien Giang province was the most vulnerable to climate change and variability, followed by Can Tho province. The findings suggest that intervention programmes strengthen communication networks among farmers and those local governments and other organisations to provide subsidies and training courses for farmers to cope with climatic events, as well as create more opportunities for them to diversify their income sources.

Groupers (family Epinephelidae, subfamily Epinephelinae) are reef fishes of high value as food resources that generate export revenue to Sri Lanka. Yet, with less attention and poor resource management, grouper population dynamics remain understudied. This paper investigates the temporal variation of grouper species on the continental shelf of Sri Lanka in relation to seasonal, regional, and seafloor depth variables using data based on quantitative sampling of demersal fish conducted in 1978, 1979, 1980, and 2018 with a bottom trawl on the R/V Dr. Fridtjof Nansen, where the authors joined the 2018 survey. A total of 277 trawl samples were included in the analysis. The analysis of variance of all the grouper species found that the average density significantly declined from 0.89 t/NM2 (tonnes per square nautical mile) in 1979 to 0.28 t/NM2 in 2018. The contribution of groupers to the total catch (by weight) was also higher in 1979 (9.06 %) than in 2018 (1.28 %). The distribution patterns significantly differed among the six regions of the Sri Lankan shelf. In addition, seafloor depth was negatively correlated with grouper density. The results point to an urgent need for better management and conservation of the grouper resources.

Management of plantation forests for multiple purposes is critically important in the fight against climate change and loss of natural forests. This study aims to assess bioenergy generation, timber production, carbon emission reductions, carbon removals, and related carbon revenues through the management of plantation forests in Myanmar. We used the latest data from the forest resource assessment to develop the forest land use and growing stocks models for fast-growing and slow-growing plantation forests between 2000 and 2040. We found that natural forests lost 2.6% annually but only 0.02% was converted to plantation forests. Total growing stocks for both forest types increased from just 8.9 million m3 in 2000 to 39.8 million m3 in 2040. Total carbon removals were 1.2 Tg CO2 yr-1 between 2000 and 2040 and 1.3 Tg CO2 yr-1 during the Paris Agreement timeframe. The use of thinned wood and wood biomasses to substitute the fossil combustion could reduce 12.7 Tg CO2 yr-1 of carbon emissions. If combined, total emission reductions from bioenergy generation and carbon removals accounts for 82% of Myanmar’s total emissions in energy sector. This study concludes that management of plantation forest could contribute to climate change mitigation while reducing timber demand from natural forests.

There is an emerging body of literature focusing on the COVID-19 livelihoods and environmental impacts, as well as the effects of the pandemics on evidence generation. However, little attention has been paid to how COVID-19 has—and is likely to continue to—affect monitoring, evaluation, and learning (MEL) systems, specifically in the context of large sustainability science research-to-policy project consortia. Here, we provide a conceptual framework of MEL responsiveness to COVID-19 effects and discuss the specific pathways to successful MEL transition. Using the UKRI GCRF TRADE Hub as a case study, we provide some examples of possible adjustments within the new context.

The productivity gains attained from high-yielding varieties (HYV) of rice (Oryzasativa L.) developed during the Green Revolution are no longer sufficient to feed the increasing populace. This has led to a greater focus on hybrid rice (developed by crossing two inbred varieties). However, the adoption of hybrid rice is stagnant in Bangladesh. This study assessed the current status of hybrid vis-à-vis HYV rice, the problems in the adoption of hybrid rice, and the potential of hybrid rice in increasing productivity and farmers’ income. The technical efficiency of rice cultivation and determinants of inefficiency were also investigated in addition to the development of various optimal land utilization scenarios. Primary data from 400 randomly selected farmers were collected in 2016 from four districts, Dinajpur, Sherpur, Gopalganj, and Noakhali, in Bangladesh. The analytical methods included the marginal benefit-cost ratio, stochastic production possibility frontier, and linear programming. The results showed that hybrid rice had higher productivity (20–25%) than HYV rice, while the marginal benefit-cost ratios were higher than one (3.65–5.34) across all the sampled districts. The area under hybrid rice decreased and the growth rate was negative (–2.52%) during the study period due to the rising price of seed and insect infestation. Based on land utilization scenarios, the optimal land utilization would require reallocation of 8–52% rice area in favor of hybrid rice across the sampled districts. The efficiency analysis showed the mean technical efficiency of 76%, which indicated the presence of technical inefficiency in rice production, significantly affecting the outputs. Farmer's education and extension service access were the main avenues for reducing inefficiency. As hybrid rice has higher productivity and profitability, hybrid seeds provide opportunities for enhancing rice production in Bangladesh. Yet, this can only be achieved by developing and disseminating affordable hybrid seeds with insect pest resistance and improved palatability of grain. The concerned government departments should also provide better access to extension services to reduce production inefficiencies.

Understanding the drivers of deforestation and forest degradation and the agents of such drivers is important for introducing appropriate policy interventions. Here, we identified drivers and agents of drivers through the analysis of local perceptions using questionnaire surveys, focus group discussions, and field observations. The Likert scale technique was employed for designing the questionnaire with scores ranging from 1 (strongly disagree) to 5 (strongly agree). We found nine direct drivers of forest deforestation and forest degradation, namely illegal logging (4.53 ± 0.60, ± is for standard deviation), commercial wood production (4.20 ± 0.71), land clearing for commercial agriculture (4.19 ± 1.15), charcoal production (3.60 ± 1.12), land clearing for subsistence agriculture (3.54 ± 0.75), new settlement and land migration (3.43 ± 0.81), natural disasters (3.31 ± 0.96), human-induced forest fires (3.25 ± 0.96), and fuelwood for domestic consumption (3.21 ± 0.77). We also found four main indirect drivers, namely lack of law enforcement, demand for timber, land tenure right, and population growth. Our analysis indicates that wood furniture makers, medium and large-scale agricultural investors, charcoal makers, land migrants, firewood collectors, and subsistent farmers were the agents of these drivers. Through focus group discussions, 12 activities were agreed upon and could be introduced to reduce these drivers. In addition to enforcing the laws, creating income-generating opportunities for locals along with the provision of environmental education could ensure long-term reduction of these drivers. The REDD+ project could be an option for creating local income opportunities, while reducing deforestation and forest degradation.

A farmer’s decision to adopt sustainable land management practices often takes place in a changing context. In the Northeast Region of Thailand, rural areas face a deagrarianization process and the dominant farming system – small-scale rice farming under rainfed conditions – is losing its role as the main provider of household income. The study applies a mixed approach to investigate the reasons why farmers adopt sustainable land management practices in this region. This approach involved a quantitative assessment of factors that influence adoption and a qualitative analysis of local actors’ opinions regarding these reasons. Two major reasons were identified: the engagement in diversifying production and the willingness to reduce the amount of time household members spend farming. These two reasons relate to two strategies farmers use to adapt to ongoing changes: getting involved in changing the farm or maintaining it while limiting the effort they spend running the farm. Initiatives to enhance the uptake of sustainable land management practices in the Northeast Region of Thailand would benefit from structuring the support provided taking these two strategies into account.

Climate-change mitigation projects are expected to improve local livelihoods in targeted areas. Several REDD+ projects aimed at reducing emissions from deforestation and forest degradation, conserving and enhancing forest carbon stocks, and sustainably managing forests have been implemented in Cambodia but few studies have examined the effects on local livelihoods before and during project implementation. Our study applies a sustainable livelihood framework to assess the livelihood assets of local communities in the Oddar Meanchey and Keo Seima REDD+ project sites in Cambodia before and during project implementation. Five capital assets, namely natural, physical, human, financial, and social capital, are assessed and scored on a 1-to-5 Likert scale. Data analysis collected through 252 interviews in Oddar Meanchey and Keo Seima reveals a slight increase in livelihood assets in both sites from project validation to implementation. Generally, the mean scores for local livelihood assets increased from 2.81 ± 0.07 (±is followed by the standard error) and 2.66 ± 0.06 to 3.07 ± 0.09 and 3.06 ± 0.08 in Oddar Meanchey and Keo Seima, respectively. Nevertheless, natural capital assets sharply declined from 3.50 and 3.32 to 2.09 and 2.25, respectively. Respondents mainly blamed illegal logging for the decline, suggesting that strict patrolling and enforcement must be implemented. Furthermore, the scarcity of carbon-credit buyers and the projects' inability to generate carbon-based revenues has led to dissatisfaction among local communities, inducing avoidable illegal activities in pursuit of short-term benefits. A financial mechanism to ensure sufficient and sustained financial support regardless of carbon-market volatility is urgently needed.

In recent years, international attention has been rendered to development of ecotourism for poverty reduction and biodiversity conservation. We assessed local livelihood assets in Kampong Phluk Community before and after the introduction of the community-based ecotourism (CBET) governance system, where it was previously under the private company management system (SEAPAC). We used a sustainable livelihood framework to assess natural, physical, human, social, and financial assets by analyzing a set of panel data of 150 observations according to the scoring scale of zero (total dissatisfaction) to one (total satisfaction). We found that full implementation of CBET raised the overall average score of livelihood assets by 0.15. In particular, physical capital and human capital achieved remarkable growth by 0.25 to 0.23, respectively, while growth in natural capital and financial capital was statistically insignificant. Although CBET showed promising results, improving communication and providing community health care would motivate active participation in ecotourism development.

A knowledge, attitude and practice (KAP) study was conducted in three districts of Malawi to test whether the training had resulted in increased knowledge and adoption of recommended pre- and post-harvest crop management practices, and their contribution to reducing aflatoxin contamination in groundnut, maize and sorghum. The study was conducted with 900 farmers at the baseline and 624 farmers at the end-line, while 726 and 696 harvested crop samples were collected for aflatoxin testing at the baseline and end-line, respectively. Results show that the knowledge and practice of pre- and post-harvest crop management for mitigating aflatoxin were inadequate among the farmers at the baseline but somewhat improved after the training as shown at the end-line. As a result, despite unfavorable weather, the mean aflatoxin contamination level in their grain samples decreased from 83.6 to 55.8 ppb (p < 0.001). However, it was also noted that increased knowledge did not significantly change farmers’ attitude toward not consuming grade-outs because of economic incentive incompatibility, leaving potential for improving the practices further. This existing gap in the adoption of aflatoxin mitigation practices calls for approaches that take into account farmers’ needs and incentives to attain sustainable behavioral change.

The study aimed to quantify the immediate effects of dietary diversification, food safety, and hygiene interventions on child undernutrition in four rural villages in Kongwa district of central Tanzania. One hundred mothers with their children of less than 24 months old were recruited for this study. The difference-in-difference (DID) method was used to assess the effects of intensive intervention through a learning-by-doing process on the topic of aflatoxin free diversified food utilization and improved hygiene practices. Periodic anthropometric measurements were conducted on the 0th, 7th, 14th, and 21st days, and DID estimator showed the significant and positive average marginal effects of the intervention on Z-Scores being 0.459, 0.252, and 0.493 for wasting, stunting, and underweight, respectively. Notably, at the end of the study, the mean aflatoxin M1 level in urine samples decreased by 64% in the intervention group, while it decreased by 11% in the control group. The study provides quantitative evidence on intensive 21-day training for mothers incorporating integrated technologies yielded positive impacts on their children’s nutritional outcomes.

BACKGROUND This paper examines the potential for ‘Smart Food’ in contributing to the Sustainable Development Goal 2 of ending malnutrition by 2030, through a small‐scale capacity building case study in Oe Be Village, Myingyan district, Mandalay region, Myanmar. In the study site, refined white rice is the major staple followed by vegetables and animal source food in inadequate quantities. The protein intake in this particular dry zone community meets only 50% of the daily requirement and even less for children under 23 months of age. Therefore, to determine the acceptance and opportunity for legumes and millets which are produced locally, nutritious formulations was introduced for various age groups. In addition, a sensory evaluation of the recipes was conducted to test the acceptance of the nutritious products. RESULTS Two weeks of including millets and pigeonpea in the diets of children aged 6 to 23 months had a positive impact on wasting, stunting, and underweight (p = 0.002, 0.014, and 0.023, respectively). Moreover, the acceptability of these new food products by the children was found to be high. These results suggest an unexplored opportunity for specific millets rich in iron, zinc, and calcium, and for pigeonpea rich in protein, if prepared in a culturally acceptable way. CONCLUSION The impact and acceptability of this small scale and short‐term intervention indicate the potential for Smart Food products in filling the nutrition gap arising from the traditional food consumption habits in the dry zones of Myanmar.

The study assessed the potential for use of millets in mid-day school meal programs for better nutritional outcomes of children in a peri-urban region of Karnataka, India, where children conventionally consumed a fortified rice-based mid-day meal. For a three-month period, millet-based mid-day meals were fed to 1500 adolescent children at two schools, of which 136 were studied as the intervention group and were compared with 107 other children in two other schools that did not receive the intervention. The intervention design was equivalent to the parallel group, two-arm, superiority trial with a 1:1 allocation ratio. The end line allocation ratio was 1.27:1 due to attrition. It was found that there was statistically significant improvement in stunting (p = 0.000) and the body mass index (p = 0.003) in the intervention group and not in the control group (p = 0.351 and p = 0.511, respectively). The sensory evaluation revealed that all the millet-based menu items had high acceptability, with the highest scores for the following three items: finger millet idli, a steam cooked fermented savory cake; little and pearl millet bisi belle bath, a millet-lentil hot meal; and upma, a pearl and little millet-vegetable meal. These results suggest significant potential for millets to replace or supplement rice in school feeding programs for improved nutritional outcomes of children.

While development of the eco-industrial estates (EIEs) could contribute to the improvement of community livelihoods, little study was conducted to assess the performances after their implementation in Thailand. Here, we assessed the local perception on EIE performances in terms of physical, environmental, social, economic, and managerial aspects. A household survey was carried out with 220 households at four EIEs, namely Bang Phli, Gateway City, Map Ta Phut and Samut Sakhon according to various indicators of EIE development and performances using a Likert scale of 1–5. In-depth interviews with 25 key informants were also conducted to obtain qualitative information and insight. It was found that the implementation of the EIEs achieved the average score of 3.39 or 67.7%, suggesting that the implementation of the EIEs had improved the livelihoods of and gained trust from the local communities. Specifically, the economic aspect achieved the highest score (4.00), followed by the physical aspect (3.38), while the environmental aspect received only 3.11. Community members were concerned about air pollution, water pollution, dust, odors and noise. However, communities were generally satisfied with the performance of the EIEs, particularly in the economic aspect as the EIEs supported local employment and developed facilities for the communities and eventually increased community incomes and built prosperity. Our findings provide important insights for policy makers to understand and introduce effective policy interventions to further improve trust and relationship between EIEs and local communities as such trust and relationship can motivate communities to actively participate in the development of EIEs.

Aquaculture is one of the fastest growing food producing industries in the world. Aquaculture effluent contains high concentrations of inorganic nutrients. Reduction of these inorganic nutrients in aquaculture effluent is crucial for fulfilling the effluent standards or reuse of aquaculture effluent. This study investigated the effective use of green macroalga Caulerpa lentillifera as a bioremediatory species for nutrient removal from aquaculture effluent by conducting an on-station experiment and measurements. The effluent of a fish culture unit was circulated through a macroalgal culture unit every four days for a total of 60 days, allowing 15 circulations. Concentrations of inorganic nutrients (NO2−-N, NO3−-N, NH3-N, and PO43−) were measured in the integrated system consisting of a fish unit, settling unit, macroalgal unit and extra tank for water circulation in triplicates. Multiple linear regression analysis revealed that the application of the bioremediation system led to a significant reduction in nutrient concentrations within one day, and slightly further in the following two days. On average over the 15 circulations, the first one day of application decreased the concentrations of NO2−-N, NO3−-N, NH3-N, and PO43− by 0.247 mg/L, 81.6 mg/L, 0.682 mg/L, and 0.352 mg/L, respectively. Furthermore, the C:N ratio of macroalgae decreased during the 60-day application period, providing evidence of the nutrient uptake by macroalgae. Based on the European Union (EU) standard and quality criteria of France and the Joint FAO/WHO Expert Committee (JFWEC), the macroalgae grown in the integrated system were at the safe level for human consumption in terms of contents of Cd, Pb, and As. The results of our study imply that recirculating aquaculture systems utilizing C. lentillifera for biofiltration have the potential for effective treatment of aquaculture effluent integrating fish and macroalgae production.

Malawi, in south-eastern Africa, is one of the poorest countries in the world. Food security in the country hinges on rainfed systems in which maize and sorghum are staple cereals and groundnut and pigeonpea are now major grain legume crops. While the country has experienced a considerable reduction in forest lands, population growth and demand for food production have seen an increase in the area dedicated to agricultural crops. From 2010, pigeonpea developed into a major export crop, and is commonly intercropped with cereals or grown in double-up legume systems. Information on the spatial extent of these crops is useful for estimating food supply, understanding export potential, and planning policy changes as examples of various applications. Remote sensing analysis offers a number of efficient approaches to deliver spatial, reproducible data on land use and land cover (LULC) and changes therein. Moderate Resolution Imaging Spectroradiometer (MODIS) products (fortnightly and monthly) and derived phenological parameters assist in mapping cropland areas during the agricultural season, with explicit focus on redistributed farmland. Owing to its low revisit time and the availability of long-term period data, MODIS offers several advantages, e.g., the possibility of obtaining cloud-free Normalized Difference Vegetation Index (NDVI) profile and an analysis using one methodology applied to one sensor at regular acquisition dates, avoiding incomparable results. To assess the expansion of areas used in the production of pigeonpea and groundnut resulting from the release of new varieties, the spatial distribution of cropland areas was mapped using MODIS NDVI 16-day time-series products (MOD13Q1) at a spatial resolution of 250 m for the years 2010–2011 and 2016–2017. The resultant cropland extent map was validated using intensive ground survey data. Pigeonpea is mostly grown in the southern dry districts of Mulanje, Phalombe, Chiradzulu, Blantyre and Mwanza and parts of Balaka and Chikwawa as a groundnut-pigeonpea intercrop, and sorghum-pigeonpea intercrop in Mzimba district. By 2016, groundnut extent had increased in Mwanza, Mulanje, and Phalombe and fallen in Mzimba. The result indicates that the area planted with pigeonpea had increased by 29% (75,000 ha) from 2010–2011 to 2016–2017. Pigeonpea expansion in recent years has resulted from major export opportunities to Asian countries like India, and its consumption by Asian expatriates all over the world. This study provides useful information for policy changes and the prioritization of resources allocated to sustainable food production and to support smallholder farmers.
