Social, economic, and cultural dimensions of wheat stripe rust dynamics in Rawalpindi, Pakistan

The present study examined the cultural significance of wheat and the threat of wheat stripe rust (Puccinia striiformis f. sp. tritici) in Rawalpindi, Pakistan, aiming to protect wheat farming heritage, promote sustainable practices, and ensure future food security. A mixed-methods approach was employed to capture the multifaceted role of wheat within Rawalpindi’s social structure, traditions, and food security dynamics. Surveys and interviews revealed that most wheat fields were at the tillering and heading stages during the survey period. Sporadic disease outbreaks, particularly at the milking stage, were reported in areas such as Maira Shareef and Chakri villages, highlighting localized infections. To achieve the study objectives, the qualitative component involved in-depth interviews with 10 agricultural specialists in wheat cultivation and 12 experienced wheat farmers, selected through purposive sampling. For the quantitative component, stratified random sampling was used to engage 300 wheat farmers, providing broader insights into farming practices and disease awareness. A significant contrast emerged regarding awareness of wheat stripe rust disease. Although farmers expressed concern about its potential to reduce yields, much of the general population remained unaware of the disease. This underscores the importance of targeted awareness initiatives, such as grassroots campaigns delivered in local languages to address these knowledge gaps effectively. The study emphasized the need for collaborative efforts among stakeholders, including researchers, policymakers, and farmers, to develop disease-resistant wheat varieties. It also advocated for ecosystem-based pest management strategies to mitigate the impact of wheat stripe rust and ensure the sustainability of wheat farming traditions.

Food Waste to Food Security: Transition from Bioresources to Sustainability

The transition from food waste to food security is a critical component of sustainability efforts. This approach focuses on repurposing organic waste products generated throughout the food supply chain into valuable resources. Food waste, encompassing everything from agricultural residues to post-consumer waste, represents a significant untapped potential that can be harnessed to enhance food security. By implementing strategies such as composting, bioconversion, and innovative recycling technologies, biowastes can be transformed into fertilizers, animal feed, and even new food products, thus closing the loop in the food system and aiding sustainable solutions for waste valorization. This transition not only addresses environmental concerns by reducing landfill waste and greenhouse gas emissions but also contributes to economic sustainability by creating new opportunities within the food production and waste management sectors. Ultimately, transforming food waste into a resource aligns with the broader goals of a circular economy, ensuring a sustainable, resilient, and food-secure future.

Fermented vegetables, rich in probiotics, support gut health and immune function. Emerging research indicates their potential to alleviate adverse mental health symptoms such as stress and anxiety, highlighting their significance in modern dietary guidelines and chronic health management.

Sistema agroalimentar e mudanças climáticas

The future of global food security depends on an agri-food system (AFS) that is currently under direct threat from climate change. This system, essential for sustaining the world population, faces challenges that jeopardize both its functionality and sustainability. The AFS, often cited as one of the primary contributors to climate change, is also found to be highly vulnerable to its impacts. In light of this reality, sustainable and resilient alternatives are increasingly necessary. There exists a knowledge gap regarding the possibilities of transforming the AFS in alignment with climate resilience. What aspects are highlighted to understand the role of alternative approaches, agroecology, and regenerative agriculture (RA) in the reconfiguration of the agri-food system (AFS) in the context of the challenges posed by climate change? This paper aims to address this question by elucidating the main aspects of these approaches. A systematic literature review is conducted in the Web of Science and Scopus databases, followed by a SWOT analysis (strengths, weaknesses, opportunities, and threats). The key aspects identified in the review include: productive practices, actors, benefits, and challenges. Among the strengths, sustainable productive practices and the diversity of actors promoting these approaches stand out. The weaknesses include barriers to implementation and the lack of concrete evidence regarding their effectiveness in mitigating climate change. However, the need to expand the production of scientific evidence presents an opportunity. The threats are related to political barriers to the dissemination of agroecology and the lack of consensus on RA techniques.

Identification of key chlorophyll fluorescence parameters as biomarkers for dryland wheat under future climate conditions.

Nowadays, climate change is the primary factor shaping the future of food and nutritional security. To investigate the interactive effects of various climate variables on photosynthetic efficiency, an experiment was conducted using 10 dryland wheat genotypes. These genotypes were exposed to different conditions: temperatures of 25 ± 3°C and 34 ± 3°C, carbon dioxide concentrations of 380 ± 50 ppm and 800 ± 50 ppm, and irrigation regimes of 50% field capacity and well-watered. Our results indicated that the wheat genotypes responded differently to both individual and combined climate stress factors. The traditional winter wheat genotype *Sardari*, along with the newly developed dryland wheat genotype *Ivan*, exhibited resilience to anticipated climate conditions. This resilience was reflected in enhancements in photochemical quantum efficiency parameters (Y(II), qP, and qL) under combined stress conditions. Resilient genotypes demonstrated superior regulation of the stomatal conductance (GS) and electron transport rate (ETR) under elevated temperature and CO2 levels. Principal component analysis (PCA) revealed significant correlations between chlorophyll fluorescence parameters and climate factors, such as NPQ with temperature, Y(NO) with CO2, qL in response to drought stress, and both qP and Y(II) with the interactions among temperature, CO2, and drought stress. Elevated CO2 reduced the ETR and GS across all genotypes. Our findings underscore the importance of assessing not only fundamental chlorophyll fluorescence parameters like Fm and Fo but also the efficiency of NPQ and Y(II) to understand climate change impacts on dryland wheat genotypes. We suggest that these parameters could serve as valuable biomarkers for breeding programs aimed at improving plant adaptation to future dryland climate conditions.

Invisible Treasures: Assessing Indonesia’s Unique Agrobiodiversity for Food and Nutrition Security

Indonesia is a biodiversity hotspot with high levels of endemism of globally important food crops and their crop wild relatives, as well as locally adapted cultivars. This rich diversity is essential to Indonesia’s food and nutrition security, while underpinning the livelihood strategies of small-scale farmers (both men and women) and traditional communities, who act as guardians of this genetic heritage. However, many of Indonesia’s plant genetic resources for food and agriculture are experiencing genetic erosion due to increased crop uniformity and the reduced use and demand for local varieties. Changes in food preferences and consumption patterns have driven the species into agricultural neglect with only some smallholder farmers cultivating the species for cultural reasons. These problems are exacerbated by land-use changes and climate variability. Recognizing the imperative to conserve agrobiodiversity in the region to ensure future food security and sustain livelihoods, the status of conservation and sustainable use of taro, yams, cloves and nutmeg in three target provinces in Indonesia was assessed. Mixed-method analyses were used to document existing conservation efforts and what is currently known of these target crops’ conservation status, both in ex situ collections and in the field, to identify unique biodiversity, as well as the barriers and knowledge gaps on how to better conserve and use this unique genetic diversity for future generations.

Growth regulation in bread wheat via novel bioinoculant formulation

Wheat (Triticum aestivum L.) is one of the most significant crops and the backbone of food security worldwide. However, low wheat production remains a substantial concern in global agricultural systems. It can be attributed to several factors, including adverse climatic conditions, plant disease and poor soil quality. Recent efforts have explored bioinoculant applications as a promising approach to enhance wheat yield, trying to mitigate constraints essential for future wheat production and global food security. This study tested talc powder, wheat biochar, sugarcane bagasse biochar, and farmyard manure as carriers with two endophytic bacterial strains, Burkholderia phytofirmans PsJN and Bacillus spp. MN54 was applied to three wheat varieties (Ujala-16, Zincol-16, and Fathejang-16). The data was recorded at the seedling and maturity growth stages of plants. A pot experiment revealed significant improvements in plant growth following bioinoculant application compared to controls. Notably, the combination of sugarcane bagasse biochar with Bacillus sp. MN54 exhibited the most pronounced effects, promoting internodal length, spike length, tiller number per plant, grain yield per plant, and spikelets per spike. Additionally, talc powder with Bacillus sp. MN54 increased peduncle length, tiller number per plant, and spike length in Fathejang-16. These findings offer valuable insights into optimizing bioinoculant formulations for improved agricultural practices, adapting to climate change, and contributing to ensuring global food security.

Hypoxia stress: plant's sensing, responses, and tolerance mechanisms.

Oxygen (O2) is an inhibiting factor for plant growth and development in submerged and flooding environments. Plants experience different O2 concentrations, such as normoxia, hypoxia, and anoxia, which can change over space and time. Plants have evolved various morphological, physiological, and biochemical adaptations to withstand low O2 stress, many of which have been well investigated. This review provides a detailed analysis of how plants respond to hypoxia, a significant stress factor primarily caused by flooding. Hypoxia affects plants at various cellular, developmental, and environmental levels. This review highlights genetic, molecular, and metabolic adaptations crops employ to cope with O2 deficiency. The roles of various transcription factors (TFs) and gene regulation mechanisms in enabling plants to modulate their physiological responses under hypoxic conditions are notable. The review also identifies a significant gap in research on plant responses during reoxygenation, the phase of returning to normal O2 levels, especially under natural lighting conditions. This transition poses ROS generation and photoinhibition challenges, affecting plant recovery post-hypoxia. We discuss various strategies to enhance plant hypoxia tolerance, including traditional breeding, genetic modification, and grafting techniques. It emphasizes integrating these approaches with a comprehensive understanding of hypoxia sensing and response mechanisms. We underscore the complexity of plant adaptations to hypoxia and the need for continued research in this field, especially in the face of global climate change. This is vital for developing sustainable agricultural practices and ensuring future food security.

Shifts in plant architecture drive species-specific responses to drought in a Sorghum recombinant inbred line population.

Drought stress severely impedes plant growth, development, and yield. Therefore, it is critical to uncover the genetic mechanisms underlying drought resistance to ensure future food security. To identify the genetic controls of these responses in Sorghum, an agriculturally and economically important grain crop, an interspecific recombinant inbred line (RIL) population was established by crossing a domesticated inbred line of Sorghum bicolor (TX7000) with its wild relative, Sorghum propinquum. This RIL population was evaluated under drought conditions, allowing for theidentification of quantitative trait loci (QTL) that contribute to drought resistance. We detected eight QTL in the drought population that explain a significant portion of the observed variation for four traits (height, aboveground biomass, relative water content, and leaf temperature/transpiration). The allelic effects of, and the candidate genes within, these QTL emphasize: (1) the influence of domestication on drought-responsive phenotypes, such as height and aboveground biomass, and (2) how control of water uptake and/or loss can be driven by species-specific plant architecture. Our findings shed light on the interconnected roles of shoot and root responses in drought resistance as it relates to regulation of water uptake and/or loss, while the detected allelic effects demonstrate how maintenance of grain production and yield under drought is a likely result of domestication-derived drought tolerance.

The pandemics negative effect to their source of livelihood prompted them to institute drastic coping mechanisms for survival. Despite the dire situation the respondents still possess a positive outlook in life and have shown their usual resiliency to disasters. Life lessons drawn from them aided in the formulation of personal and organizational development policies in the context of the province of Masbate, Philippines. Finally, the Smart Sirungan Framework for a Food and Nutrition Secure Future was created and presented for possible utilization and further studies.

Safefood4eu: An interdisciplinary approach on education for sustainable agri-food systems in Europe

Foods are complex products consisting of many ingredients of diverse origins. Along the food supply chains, food products are prone to spoilage and safety issues, which could give rise to different health-related concerns and outcomes. Furthermore, the existing highly centralised food systems generate substantial greenhouse gas emissions and food waste. In order to strengthen the sustainable decentralised "farm-to-fork" food chains, a mindset shift supported by relevant education and policy initiatives is highly required. The ERASMUS+ KA220 project SafeFood4EU was conceived with a crucial mission - to develop an interdisciplinary and innovative toolbox of higher education and lifelong learning courses that reflect various aspects of sustainable agri-food systems. The thematic areas discussed within the SafeFood4EU project have covered food safety and supply chain management, sustainable food systems and design, food production and quality of raw materials, food authenticity and analysis, and digital and soft skills. The main objectives have been to develop a distinctive content package and make it available to the students via an e-learning management system. The project's results, aimed at creating a pool of young and capable experts, can significantly impact future food security, thereby increasing awareness about the future challenges regarding food systems transition, dietary shift and the next generation's food security.

A Comprehensive Overview on Sustainable Vegetable Gardening: Eco-friendly Approaches to Home Grown Production

Sustainable vegetable gardening is an eco-friendly practice that integrates organic farming principles, resource conservation, and biodiversity promotion to produce nutritious, chemical-free food while minimizing environmental impact. This approach emphasizes soil health through the use of organic amendments, crop rotation, composting, and mulching to improve fertility and water retention. Water conservation techniques, such as drip irrigation and rainwater harvesting, are employed to optimize water use, especially in arid regions. Pest and disease management relies on integrated pest management (IPM), biological controls, companion planting, and the use of organic pesticides to reduce chemical input while maintaining crop health. Sustainable homegrown produce has been shown to have superior nutritional content compared to commercially grown produce, and the avoidance of synthetic chemicals reduces the risk of pesticide residue exposure. Gardening fosters healthy eating habits by connecting individuals to their food sources, encouraging the consumption of fresh, unprocessed vegetables, and contributing to food security. The mental and physical health benefits of gardening, including reduced stress, increased physical activity, and improved mental well-being, further highlight its holistic value. However, challenges such as the initial setup costs, time investment, pest management, and knowledge gaps can hinder widespread adoption. Addressing these challenges requires greater access to resources, educational initiatives, and the development of climate-resilient practices tailored to specific regions. Future trends in sustainable gardening include the adoption of technological innovations, such as smart irrigation systems, automation, and vertical farming, which offer scalable solutions for urban and small-scale gardeners. The COVID-19 pandemic has underscored the importance of resilient, local food systems, and sustainable gardening is poised to play a critical role in addressing future food security concerns.

Breeding for flooding tolerance in rice: Advancements and future perspectives

Rice, the resilient grain, is cultivated in different types of ecosystems, from seacoast to hilly areas. Unfortunately, due to climate change, it frequently suffers from submergence stress during its growth period. Anoxic stress at the germination phase, flash flooding during the vegetative phase and water stagnation in low-lying areas are the major types of flooding in rice. When floodwaters rise, rice adapts. Some varieties stretch their stems toward the surface, gasping for air. Others remain dormant, conserving energy, like the FR13A landrace, SUB1 equips rice with underwater endurance. It orchestrates a genetic symphony, fine-tuning metabolic pathways and signalling survival. Some of the promising quantitative trait locus (QTLs) identified are qAG-9-2, which is responsible for anaerobic germination tolerance; qSUB1 for vegetative stage submergence tolerance, and qTIL12 for deep water adaptation. Identifying other novel QTLs and donors helps to breed varieties tolerant to different types of submergence stress. Along with Swarna SUB1, many mega-submergence-tolerant varieties have been developed and released for cultivation in Asia. As we cultivate these versatile survivors, we sow hope for a food-secure future.

Future Food Security Challenges in Riau Province, Indonesia

The food crisis is a real problem in various regions around the world, including Indonesia. This phenomenon is influenced by the rate of population growth which is increasing while farmlands are depleting due to the conversion of land into settlements, especially in Riau Province which is experiencing food security threats. Food security projections are made to provide an overview of the future condition of food security in Riau Province to support sustainability. The basic data used are data for 2018 and 2019. The measurement method used is the scenario method and then the availability calculation method according to Minister of Agriculture Regulation Number 43/Permentan/OT.140/7/2010. Meanwhile, the calculation of food needs uses a formula taking into account the average consumption per capita per year from the regional agriculture service multiplied by the population in the year concerned. Then, the projections are measured using the arithmetic population growth formula approach for food availability and the geometric population growth formula for the food needs of the population. The food commodity in Riau Province used in the analysis is rice. The calculation results show that in the future food availability in Riau Province will not be able to meet its food needs. Keywords: availability of rice, rice needs, food security

Will a plant germplasm accession conserved in a genebank change genetically over time?

The simplified question on the genetic change of a conserved plant germplasm accession over time is raised for a better understanding of the challenging mission of conserving more than 7.4 million germplasm accessions in 2000 genebanks worldwide for generations to come. Its answer will influence how these genebanks operate to ensure the continued survival and availability of the conserved plant genetic resources for future food security. Here, we explore the expected impact of evolutionary forces on plant germplasm in genebanks, search for the theoretical expectations and empirical evidence for such impacts from the literature, and discuss the ramifications of the evidence for long-term plant germplasm management and conservation. It is expected that genetic changes of long-term conserved germplasm under genebank conditions will occur commonly as an evolutionary rule, not as an exception. Incorporating evolutionary biology into the Genebank Standards and operational procedures will benefit the mission of long-term germplasm conservation.

Ecogeographic Study of Ipomoea Species in Mauritius, Indian Ocean.

The wild relatives of crops play a critical role in enhancing agricultural resilience and sustainability by contributing valuable traits for crop improvement. Shifts in climatic conditions and human activities threaten plant genetic resources for food and agriculture (PGRFA), jeopardizing contributions to future food production and security. Studies and inventories of the extant agrobiodiversity, in terms of numbers and distribution patterns of species and their genetic diversity, are primordial for developing effective and comprehensive conservation strategies. We conducted an ecogeographic study on Ipomoea species and assessed their diversity, distribution, and ecological preferences across different topographic, altitudinal, geographical, and climatic gradients, at a total of 450 sites across Mauritius. Species distribution maps overlaid with climatic data highlighted specific ecological distribution. Principal Component Analysis (PCA) revealed species distribution was influenced by geographical factors. Regional richness analyses indicated varying densities, with some species exhibiting localized distributions and specific ecological preferences while the other species showed diverse distribution patterns. Field surveys identified 14 species and 2 subspecies out of 21 species and 2 subspecies of Ipomoea reported in Mauritius. A gap in ex situ germplasm collections was observed and several species were identified as threatened. Further investigations and a more long-term monitoring effort to better guide conservation decisions are proposed.
