Human-induced climate change has decreased wheat production in northern Kazakhstan

Northern Kazakhstan is a major wheat exporter, contributing to food security in Central Asia and beyond. However, wheat yields fluctuate and low-producing years occur frequently. It is currently unclear to what extent human-induced climate change contributes to this. The most severe low-producing year in this century was in 2010, which had severe consequences for the food security of wheat-importing countries. Here, we present a climate impact attribution study that quantifies the impact of human-induced climate change on the average wheat production and associated economic revenues in northern Kazakhstan in the 21st century and on the likelihood of a low-production year like 2010. The study uses bias-adjusted counterfactual and factual climate model data from two large ensembles of latest-generation climate models as input to a statistical subnational yield model. We consider the climate data and the yield model as fit for purpose as first, the factual climate simulations represent the observations, second, the out-of-sample validation of the yield model performs reasonably well with a mean R 2 of 0.54, and third, the results are robust under the performed sensitivity tests. Human-induced climate change has had a critical impact on wheat production, specifically through increases in daily-minimum temperatures and extreme heat. This has resulted in a decrease in yields during 2000–2019 by approximately 6.2%–8.2% (uncertainty range of two climate models) and an increased likelihood of the 2010 low-production event by 1.5–4.7 times (10th to 90th percentile uncertainty range covering both climate models). During 2000–2019, human-induced climate change caused economic losses estimated at between 96 and 180 million USD per year (10th to 90th percentile uncertainty range covering both climate models). These results highlight the necessity for ambitious global mitigation efforts and measures to adapt wheat production to increasing temperatures, ensuring regional and global food security.

Optimizing food crop layout considering precipitation uncertainty: Balancing regional water, carbon, and economic pressures with food security

As the global food supply chain becomes increasingly unstable, food security is gaining importance in China. Nevertheless, factors such as water scarcity, limited land resources, and global climate change pose great challenges to increasing food production. Therefore, it is crucial to explore sustainable development models for food systems. In this paper, a multi-objective crop layout model considering crop rotation is constructed and solved using the INSGA2-DS algorithm. Various precipitation scenarios were established for climate change. Data analysis and optimization were conducted under different precipitation scenarios. Applied in the plain area of southwestern Shandong Province, the model can increase soybean yield by 6.78%, net carbon sequestration intensity by 0.04%, net benefit by 2.09%, and crop water productivity by 3.91% during a median flow year. Optimization tends to increase the total area planted with food crops during wet years and decrease it during dry years. The optimization model can enhance water productivity and carbon sequestration intensity of crops, as well as prevent unreasonable fluctuations in the area planted with food crops. This enables the benefits of water conservation and yield increase to be fully utilized, and reduces yield and economic losses due to dry years. The models help to rationally allocate soil and water resources, effectively respond to climate change risks, and provide robust decision support for regional food crop planning.

Spatiotemporal dynamic of rice production and its carbon footprint in Hainan, China: Implications for food security and environmental sustainability.

Rice (Oryza sativa L.) feeds more than half of the global population and faces the critical issues related to food security and environmental sustainability. This study analyzed double rice production data from 2010 to 2020 to assess its spatiotemporal dynamic in food production and carbon (C) footprint in Hainan province, China. The results revealed a 29.5% reduction in rice planting area, leading to a significantly decreased rice self-sufficiency rate from 38% to 33% from 2010 to 2020. During this period, the carbon footprint per unit area (CFa) for early, late, and double rice showed a fluctuating upward trend ranging from 8.1 to 8.4, 8.9 to 9.2, and 17.0 to 17.4 t CO2-eq ha-1, respectively. The total greenhouse gas (GHG) emissions of rice production decreased to around 2 million t CO2-eq, primarily due to reduced planting area. The C sequestration initially increased before decreasing to 1.2 million t C in 2020 at a temporal scale. Spatially, the northeast and southwest regions exhibited ∼70% of the total GHG emissions and ∼80% of C sequestration. The regional C footprint per unit yield displayed less favorable outcomes, with some areas (e.g., Wenchang and Haikou) experiencing emission hotspots in recent years. Higher yield and smaller CFa for Lingao and Tunchang were observed compared to the average between 2010 and 2020. This study provides insights into the spatiotemporal dynamics of double rice production and GHG emissions in Hainan, offering a scientific reference for regional food security and environmental sustainability.

Beyond Reach: Social Media Performance as A Key Metricfor Marketing Success

Social media is now an integral part of business activities. Companies that manage social media effectively can experience significant benefits in improving their marketing performance. Study results show that there are still many businesses that have not developed effective social media strategies in their marketing efforts. This study explores the social media marketing strategies that Micro, Small, and Medium Enterprises (SMEs) should adopt to improve their social media performance, which in turn will improve overall marketing results. To achieve optimal social media performance, social media marketing strategies adopted by SMEs should involve Social Media based Customer Engagement. This study adopted a quantitative approach and collected data from 265 SMEs in the food and beverage sector in Semarang, Solo, Kudus, and Jepara regions using a purposive sampling method. Data collected through questionnaires were used to test the empirical model using Structural Equation Modelling (SEM-AMOS). The results showed that the implementation of effective social media marketing strategies by SMEs can increase Social Media-based Customer Engagement, which in turn will have a positive impact on their social media performance. Increased customer engagement through social media can also be strengthened by the Brand Exposure strategy applied in marketing through social media.

Challenges in urban-rural food supply chains for disaster resilience in Nepal

Urban and rural areas are interconnected in fulfilling the food demands of both sides. However, both unprecedented and predictable disasters are disrupting the food service. To address this issue, this paper discusses the need and significance of urban-rural coordination, which promotes use of local resources, solving direct and indirect problems related to food. A smooth food system chain with adequate storage capacity, transportation, and food quality is essential not only during normal days but also throughout times of disaster. Therefore, this research aims to identify the factors disrupting the food system chain in the mid-hill area of Nepal. It explores the interconnection between urban and rural areas in maintaining the food system chain and investigates ways to improve it from a disaster resilience perspective. Kathmandu and Melamchi, urban and rural areas in Nepal are taken for the study. After completing interviews with disaster victims, focus group discussion was conducted with farmers, municipality government officers, disaster experts, and local people. Additionally, further discussion held with traders who are mainly involved in the food system chain from the disaster resilience perspective. Grains, milk, and vegetables primarily flow from rural areas to Kathmandu, while manufactured goods are predominantly supplied from urban areas. The food supply chain services are generally disrupted every monsoon season due to floods and were severely affected during the 2021 flood in the Melamchi area. The results of the study are clustered into five categories, depending on the city region's food system cycle.

Fluoride exposure from consumption of some animal-based foods in an outermost region of Europe

Fluoride is an anion that is widely distributed in nature and can be found in varying levels in water supplies and foodstuffs. This study has been carried out considering the toxic effects in cases of chronic and high fluoride intake and the presence of this anion in foods of animal origin. The fluoride content in a total of 96 samples of animal origin (meat, poultry and poultry products; fish and seafood; milk, dairy products and eggs) was determined by potentiometry with a fluoride selective electrode (ISE). The overall mean concentration was 3.92 ± 6.04 mg/kg, with a minimum for milk (values below the detection limit of 0.01 mg/kg) and a maximum for shrimps (32.1 mg/kg). Seafood was found to have the highest fluoride concentrations and the estimated daily intake (EDI) and the percentage contribution to the adequate intake (AI) and upper-level intake (UL) were calculated. Overall, the percentage contribution to UL was less than 20 %. It was concluded that the intake of the analysed animal-based foods does not pose a toxic risk.

Assessing the effects of plant density and nitrogen on millet yield in Southern Niger using the CERES-millet model

BackgroundThe dryland production environments in Niger Republic (Niger) generate variable crop production risks that reduce crop yields and increase regional food insecurity. Optimal combinations of crop varieties and management are needed to maximize crop water-limited yields in these environments.MethodsIn this study, we calibrated and validated the CERES-Millet model using data from field experiments. Seasonal analysis (1984–2020) was carried out in 18 selected sites across the three agroecological zones (AEZs) to test the effects of plant density and N fertilization on grain yield. The treatment included five different plant densities (1.5, 3, 6, 9, and 12 plants m−2) and four N rates (0, 20, 40, and 60 kg N ha−1). Three millet varieties (CHAKTI, HKP, and SOSAT-C88) were compared. Millet production risk was assessed at each AEZ using cumulative probability distribution graphs. The acceptable grain yield required to compensate for the minimum production cost of millet in Niger was set to 975 kg ha−1 (75th percentile of the simulated data).ResultsThe CERES-Millet model reasonably reproduced number of days to flowering (d-index > 0.50; RMSE < 2 days), number of days to maturity (d-index > 0.50; RMSE < 2 days), and grain yield d-index > 0.78; RMSE < 100 kg ha−1) for all the three varieties. The results showed that there was significant response to N (40 – 110% yield increase following N application) and plant density (30–80% yield increase by increasing density above 1.5 plants m−2) in all the AEZs depending on variety. The SOSAT was the most responsive variety to N application and plant density in all AEZs. Under low N application (0–20 kg ha−1) and low (1.5—3 plants m−2) to moderate plant density (6 plants m−2), CHAKTI and HKP had the highest production risks. Increasing N application above 20 kg ha−1 mitigate these risks where grain yield was above the 975 kg ha−1 threshold representing the minimum production cost for millet in more than 50% of the years under all plant densities except in Sahel where this threshold was only achieved in < 20% of the years. In all AEZs, increasing plant density above 6 plants m−2 increases this risk under low to moderate N application, but the downside risk was mitigated when N was applied at high rates.ConclusionThis study demonstrated N application rate and plant density recommendations must be tailored to specific variety and AEZs to maximize grain yield and reduce volatility in Niger.

Availability and accessibility of indigenous foods in Gauteng region, South Africa

While South Africa maintains national food security, food insecurity persists at the household level, with not all households having access to sufficient food. Proposals to address this include promoting the consumption of indigenous foods (IF). However, urbanization in the Gauteng region has sparked a nutrition transition, characterized by increased consumption of Western diets, resulting in rising rates of malnutrition and non-communicable diseases. This study sought to assess the availability and accessibility of indigenous foods in the region for residents. A quantitative cross-sectional research survey was conducted in the Gauteng region, involving 746 participants who provided insights into their ways of acquiring indigenous foods and rated their overall availability. Additionally, the survey gathered opinions on IF availability across different settings and collected suggestions for improving IF accessibility. Among a list of 18 South African indigenous foods, between 55.2 and 77.2% of participants did not know where they could be obtained. Acquisition through vendors, with a maximum of 14% of respondents, emerged as relatively more popular compared to food markets, spaza shops, supermarkets, and home gardens. The majority of surveyed participants (55%) perceived indigenous foods as unavailable in the region. Agreement rates for the availability of indigenous foods for sale or serving in various settings were 53.5% for supermarkets, 42% for schools, 44.2% for hospitals, and 37.5% for workplaces. Respondents suggested several strategies to enhance IF accessibility in the region, including marketing, home gardens, farms, supermarkets, education, elders, restaurants, and schools/universities. Overall, there is a need for increased education on the nutritional benefits of indigenous foods and the implementation of policies to improve their accessibility in urbanized provinces like Gauteng.

RSM- and ANN-Based Multifrequency Ultrasonic Extraction of Polyphenol-Rich Sargassum horneri Extracts Exerting Antioxidative Activity via the Regulation of MAPK/Nrf2/HO-1 Machinery.

Sargassum horneri (SH) is widely consumed as a healthy seaweed food in the Asia-Pacific region. However, the bioactive components contributing to its biological activity remain unknown. Herein, we optimized multifrequency ultrasonic-assisted extraction conditions to achieve higher antioxidant activity using a response surface methodology and an artificial neural network. High-resolution mass spectrometry (HRMS; negative mode) was used to tentatively identify the secondary metabolites in the optimized SH extract, which were further tested against oxidative stress in RAW264.7 cells. Additionally, the identified compounds were analyzed in silico to determine their binding energies with the Keap1 protein (4L7B). We identified 89 compounds using HRMS, among which 19 metabolites (8 polyphenolics, 2 flavonoids, 2 lignans, 2 terpenes, 2 tannins, 2 sulfolipids, and 1 phospholipid) were putatively reported for the first time in SH. The in vitro results revealed that optimized SH extract inhibited oxidative stress via the Nrf2/MAPKs/HO-1 pathway in a dose-dependent manner. This result was validated by performing in silico simulation, indicating that sargaquinoic acid and glycitein-7-O-glucuronide had the highest binding energies (-9.20 and -9.52 Kcal/mol, respectively) toward Keap1 (4L7B). This study offers a unique approach for the scientific community to identify potential bioactive compounds by optimizing the multivariant extraction processing conditions, which could be used to develop functional and nutraceutical foods.

Food Hub or Not Yet? Exploring the Food Hub Milieu in Czechia

Abstract In global research, food hubs are evaluated as a suitable tool for the development of alternative food networks and the transformation of the agri-food system towards sustainability. However, in Europe, research conclusions in recent years point to a lack of knowledge about operating food hubs. Expanding information about how food hubs work is crucial for improving their operational effectiveness and establishing support from the public sector. Therefore, this exploratory research aims to discover examples of food hubs in Czechia where the term "food hub" is not used and no appropriate equivalent has been developed. This leads to the task of determining the criteria under which it is possible to define existing entities as food hubs. Using several examples supported by qualitative research, the article opens a discussion about the acceptability of the hybridization of alternative food networks. Our findings contribute to the debate about the potential of food hubs to develop local and regional food markets, especially in the context of post-socialist countries, where the conditions are different from the Western states.

Flash droughts in a hotspot region: Spatiotemporal patterns, possible climatic drivings and ecological impacts

Northeast China, recognized as a global flash drought hotspot and a region of nationally important commercial grains and ecological fragility, is highly susceptible to the profound impacts of droughts on both food security and ecological safety. However, the regional-scale characteristics, possible causes and impacts of flash droughts across Northeast China are rarely investigated. Soil moisture data from 2000 to 2022 were utilized to identify the onset, frequency and duration of flash droughts using the quantile method. The spatial trajectories of flash droughts were determined based on the patch-scale centroid transfers. Further, the possible drivings and ecological impacts of flash droughts were analyzed using datasets of climatic variables and gross primary productivity. We found that flash drought coverage with short onset (1- pentad onset) was generally larger than that with long onset (2-, 3- and 4-pentad onset). The affected area of flash droughts generally decreased, while the onset speed increased over the past two decades. Flash droughts frequently occurred the intersection of western Jilin Province, southern Inner Mongolia Autonomous Region, and northern Liaoning Province but with short duration. Compared with 2001–2011, the start, middle and end centroids of flash droughts in 2012–2021 showed more spatial dynamic changes, mainly shifting towards the northeast-southwest and southeast-northwest directions. The onset of flash drought due to potential evapotranspiration, temperature, precipitation deficit, and vapor pressure anomalies account for an average of 33%, 28%, 22%, and 16%, respectively. However, the contributions of dominant meteorological factors and their combinations varied remarkably in different sub-regions. Long onset flash droughts exhibited larger impact on GPP than short onset flash droughts. This study highlights that due to climate change, the affected area of flash droughts in hotspot regions decreased, but the onset speed and spatial dynamics increased, and followed by a more severe ecological impact of short-onset flash drought. Therefore, it is imperative to incorporate the increasing impacts of flash droughts, which is critical to ensuring regional food security and ecological safety in the Northeast China.

Determining the plant-pollinator network in a culturally significant food and medicine garden in the Great Lakes region.

Understanding the interactions between plants and pollinators within a system can provide information about pollination requirements and the degree to which species contribute to floral reproductive success. Past research has focused largely on interactions within monocultured agricultural systems and only somewhat on wild pollination networks. This study focuses on the culturally significant Three Sisters Garden, which has been grown and tended by many Indigenous peoples for generations in the Great Lakes Region. Here, the plant-pollinator network of the traditional Three Sisters Garden with the inclusion of some additional culturally significant plants was mapped. Important visitors in this system included the common eastern bumble bee, Bombus impatiens Cresson (Hymenoptera: Apidae), and the hoary squash bee, Xenoglossa pruinosa (Say) (Hymenoptera: Apidae), as determined by their abundances and pollinator service index (PSI) values. Understanding the key pollinators in the Three Sisters Garden links biological diversity to cultural diversity through the pollination of culturally significant plants. Further, this information could be of use in supporting Indigenous food sovereignty by providing knowledge about which wild pollinators could be supported to increase fruit and seed set within the Three Sisters Garden. Our findings can also lead to more effective conservation of important wild pollinator species.

Examining climate trends and patterns and their implications for agricultural productivity in Bagamoyo District, Tanzania

Climate variability impacts various global challenges, including food security, biodiversity loss, water scarcity, and human well-being. However, climate patterns and trends and community perceptions at spatially-explicit levels have been minimally addressed. The spatial and temporal trends of climate conditions in Bagamoyo District in Tanzania were examined using historical (1983–2010) and projected (2022–2050) meteorological and climate model data, respectively. Community knowledge and experiences of past climate occurrences were included. The implications of projected climate change for regional agricultural production and food security were assessed. The study drew on empirical data obtained from household surveys conducted in seven villages in the district. Effectively, 309 households were randomly sampled across the villages to provide the perception of climate change and associated impacts on agriculture and livelihoods. Both qualitative and quantitative statistical techniques were employed to analyse the incidence, frequency, and intensity of regional extreme climate events. The meteorological and climate modelling data were subjected to trend analysis using the Mann–Kendall and Sen’s slope estimator tests, and the present and projected spatial and temporal trends of climatic variables in the region were analysed. The household-based questionnaire results were combined with climate modelling and the literature to determine the implications of climate change for regional agricultural production and food security. The results revealed that local knowledge and climate model data strongly concur on regional climate changes. Furthermore, the region is highly likely to experience increased warming and decreased precipitation at varying magnitudes. The shifts in climate trends and patterns are anticipated to greatly impact agricultural production, affecting livelihoods and hampering food security efforts. Recommendations include adopting context-specific measures and tailored strategies for enhancing resilience throughout the entire region.

Review of Crop Wild Relative Conservation and Use in West Asia and North Africa.

Ensuring global food security in the face of climate change is critical to human survival. With a predicted human population of 9.6 billion in 2050 and the demand for food supplies expected to increase by 60% globally, but with a parallel potential reduction in crop production for wheat by 6.0%, rice by 3.2%, maize by 7.4%, and soybean by 3.1% by the end of the century, maintaining future food security will be a challenge. One potential solution is new climate-smart varieties created using the breadth of diversity inherent in crop wild relatives (CWRs). Yet CWRs are threatened, with 16-35% regarded as threatened and a significantly higher percentage suffering genetic erosion. Additionally, they are under-conserved, 95% requiring additional ex situ collections and less than 1% being actively conserved in situ; they also often grow naturally in disturbed habitats limiting standard conservation measures. The urgent requirement for active CWR conservation is widely recognized in the global policy context (Convention on Biological Diversity post-2020 Global Biodiversity Framework, UN Sustainable Development Goals, the FAO Second Global Plan of Action for PGRFA, and the FAO Framework for Action on Biodiversity for Food and Agriculture) and breeders highlight that the lack of CWR diversity is unnecessarily limiting crop improvement. CWRs are not spread evenly across the globe; they are focused in hotspots and the hottest region for CWR diversity is in West Asia and North Africa (WANA). The region has about 40% of global priority taxa and the top 17 countries with maximum numbers of CWR taxa per unit area are all in WANA. Therefore, improved CWR active conservation in WANA is not only a regional but a critical global priority. To assist in the achievement of this goal, we will review the following topics for CWRs in the WANA region: (1) conservation status, (2) community-based conservation, (3) threat status, (4) diversity use, (5) CURE-CWR hub: (ICARDA Centre of Excellence), and (6) recommendations for research priorities. The implementation of the recommendations is likely to significantly improve CWRs in situ and ex situ conservation and will potentially at least double the availability of the full breadth of CWR diversity found in WANA to breeders, and so enhance regional and global food and nutritional security.

The impact of urbanization on food security in China

Against the background of urbanization's rapid development in China from 1984 to 2020, this research evaluates the mechanisms of its impact and food security by constructing a comprehensive evaluation index system for regional food security and verifying urbanization's spatial spillover effect on such security. We present the following findings. (1) A greater level of urbanization has a clear spatial effect on improving the level of food security in China. (2) Urbanization development plays a vital role in advancing local food security and at the same time has a greater negative impact on expanding surrounding food security. (3) The spatial spillover effects of urbanization on food security vary greatly, often according to different levels of regional economic development and natural geographic settings. This paper offers recommendations for controlling regional urbanization development, improving the radiation-driven role of urbanization, and implementing differentiated regional policies.

Addressing the opportunities of non‐thermal food processing technologies in the ASEAN region context

SummaryThis study aims to explore the opportunities offered by non‐thermal food processing technologies, including high‐pressure processing, pulsed electric fields, ultraviolet light, ultrasound, and microwave that could be viable for the agriculture commodities produced in the ASEAN region. The applications of these technologies across various food product categories (from dairy to fruits and vegetables, meat and seafood, beverages, condiments, fermented foods, edible oil, and ready‐to‐eat meals) focusing on microbial inactivation and mass transfer process enhancement, are systematically discussed to highlight their potential to foster the production of safe, nutritious, and fresh‐like quality food products from the region. The adoption of non‐thermal technologies can face several challenges that hinder the integration of these technologies in ASEAN, including high start‐up costs, limited access to stable electricity and clean water, and inconsistencies in food regulations across countries. Information gaps related to the adoption of non‐thermal technologies within the diverse food‐related scenarios in ASEAN were identified and recommendations were given to improve the state of knowledge in the region. Overall, this work offers critical insights for policymakers, industry stakeholders, and researchers to consider inclusion of non‐thermal technologies in food production as strategic approaches and tailored solutions to enhance the competitiveness of regional food products globally.

Food democracy as food security strategy: The case of a Costa Rican tourism town

Tourism communities such as Monteverde, Costa Rica, the site of this study, have been profoundly impacted by the loss of tourism revenue during COVID-19. Faced with intensified food insecurity caused by the cascading impacts of this pandemic, the community has organized initiatives to stimu­late local, sustainable food production to increase food security during the COVID-19 economic recovery. This paper adopts a food democracy framework to analyze restaurants’ regional food purchases, barriers to local purchasing, and tour­ists’ interest in and ability to identify local food products. Our findings show that nearly all restaurant owners identified benefits of purchasing regional food but reported multiple barriers to buying locally. Tourists reported high interest in eating locally produced food but do not have enough information to identify farm-to-fork options. Local food initiative stakeholder inter­views show that emergent strategies demonstrate a move toward food democracy actions by promot­ing communication and co-learning between res­taurants, food producers, and tourists to rein­force principles of food democracy. Based on our find­ings, we recommend (a) strengthening producer-to-restaurant networks, (b) enhancing communication of local food production benefits and responsi­bilities to restaurants, and (c) promot­ing the locally made certification for restaurants to strengthen localized food networks and direct tourists to transformative food strategies underway in Monteverde.

Nutritional profiles of Middle Eastern dishes and composition

The study examined 27 traditional Middle Eastern/Kuwaiti dishes, primarily meat, chicken, and fish-based, to assess their taste and nutritional content. The evaluation included protein, moisture, carbohydrates, ash, fat, energy, dietary fiber, 11 vitamins, 8 minerals, and 3 sugars. Certain dishes displayed high levels of protein, fat, energy, water, carbohydrates, and dietary fiber. For instance, Marag laham and Majbous dajaj stood out for their high protein, fat, and energy content. Additionally, Marag laham and Marag dajaj exhibited high water content of 63.55% and 69.42% respectively for the meat and chicken section, while Majbous laham and Majbous dajaj had elevated carbohydrate levels due to the rice (27.52%). Notably, Turkey and Arabic meat shawarma had the highest fat energy with Arabic meat shawerma energy calculated at 400.91 kcal due to its total fat content (31.74%). The study concludes that using standard recipes for common meals can facilitate the collection of global and regional food composition data, which can be integrated into global food composition databases for diverse ethnic communities. Overall, the research highlights the importance of considering both taste and nutrition when making food choices and supports making informed dietary decisions based on comprehensive nutritional information

The Impact of Trade Openness, Tariff, and Globalization on Food Security in the ASEAN Region

In 2023, many crises hit the world due to heated geopolitical conditions resulting from the war in Russia and Ukraine; the world situation was fragmented because of competition between the USA and PRC blocs, economic recovery due to COVID-19 was shaken again, and food inflation was soaring high. The leading cause of food insecurity in ASEAN, which consists of most developing countries, is the lack of distribution access due to the affordability of logistics and food supplies. Most investors shift their investment preferences from the primary sector to manufacturing due to the volatility and high risk of assets. In 2020, in Asia, there were 78.7 million toddlers who were stunted, with the second majority in Southeast Asia (27.40%). Although most of the ASEAN member countries are connected geographically, the market share of ASEAN member countries in world trade is only 8.8%, so intra-trade relations are considered not optimal enough. This study aims to analyze the effect of three different trade openness indicators (trade openness, tariffs, and globalization) on the food security of Southeast Asian people in 2000–2021. The method used in this research is panel data, which combines pool least squares (PLS) and fixed effect models (FEM) by developing Beck and Katz’s two panels corrected standard errors (PCSE): cross-section weights and SUR. Trade openness significantly affects the two pillars of food security: stability and utilization, with U-shaped results. Ad-valorem tariffs are significant and positive for the two pillars of food security: availability and utilization. Increasing taxes in Southeast Asia can improve the average dietary energy supply’s adequacy; however, this can also increase the prevalence of stunting in children under five. It happens because the availability of abundant food in terms of quantity differs from the quality and safety of its consumption. The increase in globalization from an economic, political, and social perspective in Southeast Asia is significant for the four pillars of food security; if globalization is increased, then this can positively impact reducing cases of stunting and malnutrition; on the other hand, increasing globalization has harmed food availability and stability. Increasing one policy has a different impact. In the first stage, policy improvements can positively impact a pillar of food security. However, after reaching a turning point, there is a possibility that the increased policy will harm the other pillars. Therefore, it is necessary to choose an integrative policy trade-off and be able to solve problems better. This study suggests several main policy implications, namely building a more assertive trade policy based on the WTO and food safety technical rules that comply with WHO rules, increasing intra-trade within the ASEAN group, maintaining food price stability, encouraging investment in agriculture, promoting governance reforms, and strengthening the regional food security system in terms of production, consumption, and distribution. Support policies are also needed regarding solid prevention efforts against stunting and malnutrition and digitalization (Agritech 4.0), which supports food availability. In addition, this research also suggests that ASEAN can continue to increase domestic food production for resilience to the global crisis.

Unintended consequences, conflict and resilience in a small-scale irrigation development, Marakwet, Kenya

AbstractThis article examines the development, early operation and subsequent failure of the Tot-Kolowa Red Cross irrigation scheme in Kenya’s Kerio Valley. Initially conceived as a technical solution to address regional food insecurity, the scheme aimed to scale up food production through the implementation of a fixed pipe irrigation system and the provision of agricultural inputs for cash cropping. A series of unfolding circumstances, however, necessitated numerous modifications to the original design as the project became increasingly entangled with deep and complex histories of land use patterns, resource allocation and conflict. Failure to understand the complexity of these dynamics ultimately led to the project’s collapse as the region spiralled into a period of significant unrest. In tracing these events, we aim to foreground the lived realities of imposed development, including both positive and negative responses to the scheme’s participatory obligations and its wider impact on community resilience.
