Th urgency of comprehensive action is evident in the need for research collaboration between the food industry, agriculture, public health, and nutrition. This article highlights the role of philanthropy, of a non-profit organization, in supporting research and development and filling financial gaps. The article also explores the interplay of nutrition, agriculture, and government and policy, positioning philanthropy as a catalyst for transformative change and advocating for collaborative efforts to comprehensively address global food challenges. In addition, the discussion also underscores the ethical complexities surrounding charitable food aid, especially in terms of the dignity and autonomy of its recipients. The paper concludes by proposing future directions and implications, advocating for diversified intervention portfolios and collaborative efforts involving governments, businesses, and local communities. Apart from that, the importance of answering and alleviating ethical dilemmas related to food charity assistance needs to be a concern for future studies related to philanthropy because of the significant challenges faced by the contemporary food system, which include food security, health, and nutritional sustainability.

Response characteristics of root to moisture change at seedling stage of Kengyilia hirsuta.

Kengyilia hirsuta is an important pioneer plant distributed on the desertified grassland of the Qinghai-Tibet Plateau. It has strong adaptability to alpine desert habitats, so it can be used as a sand-fixing plant on sandy alpine land. To study the response mechanisms of root morphological and physiological characteristics of K. hirsuta to sandy soil moisture, 10%, 25% and 40% moisture levels were set up through potted weighing water control method. The biomass, root-shoot ratio, root architecture parameters, and biochemical parameters malondialdehyde, free proline, soluble protein, indole-3-acetic acid, abscisic acid, cytokinin, gibberellin, relative conductivity and antioxidant enzyme activities were measured in the trefoil stage, and the response mechanisms of roots at different moisture levels were analyzed. The results showed that with the increase of soil moisture, root morphological indexes such as root biomass, total root length, total root volume and total root surface increased, while the root topological index decreased continuously. The malondialdehyde content, relative conductivity, superoxide dismutase activity, peroxidase activity, catalase activity, free proline content, soluble protein content, abscisic acid content and cytokinin content at the 25% and 40% moisture levels were significantly decreased compared with the 10% level (P< 0.05). Thus, the root growth of K. hirsuta was restricted by the 10% moisture level, but supported by the 25% and 40% moisture levels. An artificial neural network revealed that total root length, total root surface area, root link average length, relative conductivity, soluble protein, free proline and moisture level were the key factors affecting root development. These research results could contribute to future agricultural sustainability.

Sacbrood Virus: A Growing Threat to Honeybees and Wild Pollinators.

Sacbrood virus (SBV) is one of the many viruses that infect both the Western honeybee (Apis mellifera) and the Eastern honeybee (Apis cerana). Recently, the interspecies transmission of SBV has been discovered, especially among wild pollinators. This newly discovered evolutionary occurrence regarding SBV indicates a much wider host range than previously believed, causing further concern about the future sustainability of agriculture and the resilience of ecosystems. Over the past few decades, vast numbers of studies have been undertaken concerning SBV infection in honeybees, and remarkable progress has been made in our understanding of the epidemiology, pathogenesis, transmission, and manifestations of SBV infection in honeybees and other pollinators. Meanwhile, some methods, including Chinese medicine, have been established to control and prevent sacbrood disease in A. cerana in Asian countries. In this review, we summarize the existing knowledge of SBV and address the gaps in the knowledge within the existing literature in the hope of providing future directions for the research and development of management strategies for controlling the spread of this deadly disease.

Recent Advancements and Development in Nano-Enabled Agriculture for Improving Abiotic Stress Tolerance in Plants.

Abiotic stresses, such as heavy metals (HMs), drought, salinity and water logging, are the foremost limiting factors that adversely affect the plant growth and crop productivity worldwide. The plants respond to such stresses by activating a series of intricate mechanisms that subsequently alter the morpho-physiological and biochemical processes. Over the past few decades, abiotic stresses in plants have been managed through marker-assisted breeding, conventional breeding, and genetic engineering approaches. With technological advancement, efficient strategies are required to cope with the harmful effects of abiotic environmental constraints to develop sustainable agriculture systems of crop production. Recently, nanotechnology has emerged as an attractive area of study with potential applications in the agricultural science, including mitigating the impacts of climate change, increasing nutrient utilization efficiency and abiotic stress management. Nanoparticles (NPs), as nanofertilizers, have gained significant attention due to their high surface area to volume ratio, eco-friendly nature, low cost, unique physicochemical properties, and improved plant productivity. Several studies have revealed the potential role of NPs in abiotic stress management. This review aims to emphasize the role of NPs in managing abiotic stresses and growth promotion to develop a cost-effective and environment friendly strategy for the future agricultural sustainability.

Improving Crop Nitrogen Use Efficiency Toward Sustainable Green Revolution.

The Green Revolution of the 1960s improved crop yields in part through the widespread cultivation of semidwarf plant varieties, which resist lodging but require a high-nitrogen (N) fertilizer input. Because environmentally degrading synthetic fertilizer use underlies current worldwide cereal yields, future agricultural sustainability demands enhanced N use efficiency (NUE). Here, we summarize the current understanding of how plants sense, uptake, and respond to N availability in the model plants that can be used to improve sustainable productivity in agriculture. Recent progress in unlocking the genetic basis of NUE within the broader context of plant systems biology has provided insights into the coordination of plant growth and nutrient assimilation and inspired the implementation of a new breeding strategy to cut fertilizer use in high-yield cereal crops. We conclude that identifying fresh targets for N sensing and response in crops would simultaneously enable improved grain productivity and NUE to launch a new Green Revolution and promote future food security.

Factors affecting arable agriculture in the future

Sustainability of arable agriculture is an important issue facing the world nowadays. The last green revolution was achieved with a mix of technologies such as chemistry, engineering and genetics. In the nearest future the need for another green revolution is could be arising but this time with less chemistry being involved as the agricultural sustainability has been degrading. The concern is massively increased for the last decades because everyone has been trying to increase agricultural production substantially but the environment has not been paid much attention. Analysis of different factors influencing the arable agriculture is key assumptions that help to understand future agricultural sustainability. Hence it is possible to identify the new targets and toward which investment must be prioritised. There are many factors that can be contributed to effect of arable agriculture but only some of them are considered in this essay which ranked as being more crucial than others. These are believed to be genetic improvement in plant breeding, adapting new policies and wise management of farming. Conclusion is that breeders and managers in agriculture must work more closely is the enormous challenge of global sustainable productivity is to be met.

ROLE OF NITROGEN SENSING AND ITS INTEGRATIVE SIGNALING PATHWAYS IN SHAPING ROOT SYSTEM ARCHITECTURE

<List> <ListItem><ItemContent> ● The Green Revolution broadened the trade-off between yield and nitrogen-use efficiency. </ItemContent></ListItem> <ListItem><ItemContent> ● Root developmental and metabolic adaptations to nitrogen availability. </ItemContent></ListItem> <ListItem><ItemContent> ● Mechanisms of nitrogen uptake and assimilation have been extensively studied. </ItemContent></ListItem> <ListItem><ItemContent> ● Modulating plant growth-metabolic coordination improves nitrogen-use efficiency in crops. </ItemContent></ListItem></List> The Green Revolution of the 1960s boosted crop yields in part through widespread production of semidwarf plant cultivars and extensive use of mineral fertilizers. The beneficial semidwarfism of cereal Green Revolution cultivars is due to the accumulation of plant growth-repressing DELLA proteins, which increases lodging resistance but requires a high-nitrogen fertilizer to obtain high yield. Given that environmentally degrading fertilizer use underpins current worldwide crop production, future agricultural sustainability needs a sustainable Green Revolution through reducing N fertilizer use while boosting grain yield above what is currently achievable. Despite a great deal of research efforts, only a few genes have been demonstrated to improve N-use efficiency in crops. The molecular mechanisms underlying the coordination between plant growth and N metabolism is still not fully understood, thus preventing significant improvement. Recent advances of how plants sense, capture and respond to varying N supply in model plants have shed light on how to improve sustainable productivity in agriculture. This review focuses on the current understanding of root developmental and metabolic adaptations to N availability, and discuss the potential approaches to improve N-use efficiency in high-yielding cereal crops.

Ensuring future agricultural sustainability in China utilizing an observationally validated nutrient recommendation approach

Fertilizer has revolutionized crop production, but a lack of evidence-based fertilizer usage has resulted in negative economic and environmental ramifications, particularly for smallholder farmers. This study aimed at developing an innovative nutrient recommendation approach, Nutrient Expert (NE), for improving yields of maize, wheat, and rice while optimizing fertilizer input through adoption of 4R (applying the right source of nutrients at the right rate, time and place) nutrient stewardship technologies, and evaluating the large-scale performance on crop productivity and the environmental impact of cropping systems. Thus, we compared NE to current farmers’ practice (FP) and soil test-based fertilizer application (ST) for 1,534 farm field experiments in order to validate the benefits of NE on both crop productivity and environmental protection in the main cereal production areas in China. Overall, the NE treatment achieved 4.4 % higher grain yield and 5.8 % more profit over FP, more yield for rice, but no differences for maize and wheat over ST. Nutrient Expert required 29.0 % and 14.7 % less fertilizer N than FP and ST, respectively. The NE recommendations improved the nitrogen (N) recovery efficiency by 10.8–13.4 percent points over FP across the 1,534 sites. Using the NE approach, on average, reactive N losses and greenhouse gas (GHG) emissions were reduced by 36.2 % and 21.5 % over FP, 16.0 % and 9.9 % over ST, respectively. The NE, as a user-friendly tool, is widely applicable across farm types and climatic regions. It could be beneficial for improving fertilizer use efficiency and maintaining strategic food security for smallholder production areas in China where N fertilizer is inappropriate and usually over applied. This approach could potentially be expanded to help reduce N losses and GHG emissions in other regions globally.

Effects of climate change on spatiotemporal patterns of tropical cyclone tracks and their implications for coastal agriculture in Myanmar

Important aspects for understanding the effects of climate change on tropical cyclones (TCs) are the frequency of TCs and their tracking patterns. Coastal areas are increasingly threatened by rising sea levels and associated storm surges brought on by TCs. Rice production in Myanmar relies strongly on low-lying coastal areas. This study aims to provide insights into the effects of global warming on TCs and the implications for sustainable development in vulnerable coastal areas in Myanmar. Using TC records from the International Best Track Archive for Climate Stewardship dataset during the 30-year period from 1983 to 2012, a hot spot analysis based on Getis-Ord (Gi*) statistics was conducted to identify the spatiotemporal patterns of TC tracks along the coast of Myanmar. The results revealed notable changes in some areas along the central to southern coasts during the study period. These included a considerable increase in TC tracks (p value < 0.01) near the Ayeyarwady Delta coast, otherwise known as “the rice bowl” of the nation. This finding aligns with trends in published studies and reinforced the observed trends with spatial statistics. With the intensification of TCs due to global warming, such a significant increase in TC experiences near the major rice-producing coastal region raises concerns about future agricultural sustainability.

Enhanced OsNLP4-OsNiR cascade confers nitrogen use efficiency by promoting tiller number in rice.

Increased use of nitrogen fertilizers has deleterious impact on the environment. Increase in yield potential at low nitrogen supply is regarded as a cereal breeding goal for future agricultural sustainability. Although natural variations of nitrogen transporters have been investigated, key genes associated with assimilation remain largely unexplored for nitrogen use efficiency (NUE) enhancement. Here, we identified a NIN‐like protein NLP4 associated with NUE through a GWAS in rice. We found that OsNLP4 transactivated OsNiR encoding nitrite reductase that was critical in nitrogen assimilation in rice. We further constructed quadrupling NREs (Nitrate‐responsive cis‐elements) in the promoter of OsNiR (p4xNRE:OsNiR) and enhanced nitrogen assimilation significantly. We demonstrated that OsNLP4‐OsNiR increased tiller number and yield through enhancing nitrogen assimilation and NUE. Our discovery highlights the genetic modulation of OsNLP4‐OsNiR signalling cascade as a strategy for high NUE and yield breeding in rice.

Localized Agri-Food Systems and Biodiversity

Interest in localized agri-food systems has grown significantly in recent years. They are associated with several benefits and are seen as important for rural development. An important share of the academic debate addresses the contribution of localized food systems to the current and/or future sustainability of agriculture. Sustainability is defined in several ways, but many scholars recognize that sustainability can only be achieved by a combination of socio-economic, cultural, and environmental aspects. However, the attributes and indicators used for sustainability analyses also differ. Biodiversity is, for instance, often not included in analyses of environmental sustainability even if biodiversity is of crucial importance for longer-term ecological sustainability. To contribute to the debate about the importance of localized food production for sustainability from the environmental point of view, specifically with regard to biodiversity, this is therefore discussed based on the results of several studies presented in this paper. The studies focus on Nordic low-intensity livestock systems related to species-rich semi-natural grasslands. All the studies show that low-intensive agriculture and use of semi-natural grasslands may play an important role in maintaining biodiversity on both small and large scales. They also show that milk and dairy products from free-ranging livestock in heterogeneous landscapes with semi-natural grasslands may have a unique quality associated with local grazing resources. Thus, producers can combine production of food of documented high nutritional and gastronomic value with maintenance of biodiversity, i.e., localized agri-food production based on low-intensive agriculture systems and semi-natural grasslands may be a win-win recipe for both farmers and the society.

Prioritization of Sub-Watersheds in a Large Semi-Arid Drainage Basin (Southern Jordan) Using Morphometric Analysis, GIS, and Multivariate Statistics

GIS-based morphometric analysis was employed to prioritize the W. Mujib-Wala watershed southern Jordan. Seventy six fourth-order sub-watersheds were prioritized using morphometric analysis of ten linear and shape parameters. Each sub-watershed is prioritized by designated ranks based on the calculated compound parameter (Cp). The total score for each sub-basin is assigned as per erosion threat. The 76 sub-basins were grouped into four categories of priority: very high (12 sub-basins, 15.8% of the total), high (32 sub-watersheds, 42.1% of the total), moderate (25 sub-watersheds, 32.9% of the total), and low (7 sub-watersheds, 9.2% of the total). Sub-watersheds categorized as very high and high are subjected to high erosion risk, thus creating an urgent need for applying soil and water conservation measures. The relative diversity in land use practices and land cover, including variation in slope and soil types, are considered in proposing suitable conservation structures for sub-watersheds connected to each priority class. The adaptation of soil conservation measures priority-wise will reduce the erosivity effect on soil loss; while increasing infiltration rates; and water availability in soil profile. Principal component analysis (PCA) reduces the basic parameters and erosion risk parameters to three components, explaining 88% of the variance. The relationships of these components to the basic and erosion risk parameters were evaluated, and then the degree of inter-correlation among the morphometric parameters was explored. The verification of priority classes obtained through morphometric analysis was tested using Discriminant Analysis (DA). The results show a complete separation existing between the identified priority classes. Thus, soil erosion risk and geomorphic conditions are found entirely different from one class to another. The present results are intended to help decision makers to plan for efficient soil and water conservation measures to achieve future agricultural sustainability in the rainfed highlands of Jordan.

The rhizosheath – a potential trait for future agricultural sustainability occurs in orders throughout the angiosperms

The rhizosheath is defined as the weight of soil adhering strongly to roots on excavation, and current interest in this trait as a potential tolerance mechanism to abiotic stress has prompted us to explore the extent of its occurrence throughout the angiosperm phylogeny. Here we describe a robust, novel method which was used to screen species for the presence/absence and strength of a rhizosheath. We correlate the latter with root hair length to provide insight into some of the factors affecting its formation. We go on to compare experimental data with previous observations in the literature. Results of a glasshouse screen demonstrate that rhizosheaths exist in species from many angiosperm orders, and the frequency of their occurrence and their strength and size are related. No correlation between root hair length and rhizosheath size was found, except when root hairs were extremely short, but the presence of root hairs was required for rhizosheath formation. The rhizosheath is present in species from many angiosperm orders. Potential to enhance the trait is likely to exist in a range of crop species and could help contribute to future agricultural sustainability.

Before the Bulldozer Hits the Ground: Measuring Farmland Loss in Ontario

Rural Ontario is in a constant state of change, as economic, environmental and political pressures impact the viability and resilience of many rural communities. Agricultural areas, in particular, are often negatively impacted by such changes, as this land may be more valuable for development purposes. Farmland is often redesignated to residential, commercial or aggregate land uses, among others, significantly impacting the viability of the agricultural industry. The future sustainability of agriculture in Ontario is dependent upon a stable land base and precise understanding of the availability of farmland. To date, accurate data regarding the amount of farmland being converted to non-farm land uses is not available as existing methods have significant limitations regarding data accuracy, consistency and timing. This research seeks to evaluate the current state of Ontario's farmland in terms of the land available and policies regarding land conservation. In order to ensure that farmland is available, it is necessary to measure the existing land base and determine the quantity of land being lost to development. This study has developed a new methodology for measuring the amount of farmland converted to non-farm land uses through official plan amendments and has been applied to nine regions and counties in southern Ontario. This presentation and poster will detail this new methodology and provide an analysis of the data collected to date. Recommendations regarding policy development, challenges associated with data collection and future research will also be presented.

Effect of growth stage based irrigation on soil water extraction and water use efficiency of spring safflower cultivars

The Ogallala Aquifer is depleting at faster rates, and jeopardizing the future sustainability of agriculture in the Southern High Plains. We hypothesize that adoption of drought tolerant crops such as safflower (Carthamus tinctorius L.) will sustain crop production in the region. However, information on water use of safflower is limited. A field study was conducted during 2013 and 2014 to monitor the soil water extraction patterns, water use efficiency (WUE) and oil productivity of spring safflower under deficit irrigation. Three safflower cultivars (PI8311, 99OL and Nutrisaff) having different growth habits and yield potentials were grown under four irrigation treatments [fully irrigated (FI), stress at vegetative stage (VS), stress at reproductive stage (RS) and dryland (DL)]. The soil water extraction was observed in all irrigation treatments or cultivars down to the depth of 1.6m in both years; however, there was difference in water extraction at each depth. Safflower exposed to water stress extracted more soil water from the deeper depths. The maximum water was extracted from 1.0 to 1.6m soil layer. The water extraction down to 1.6m from planting to harvest was the highest in RS treatment while it was next to FI treatment in terms of evapotranspiration (ET) and oil yield. The higher WUE of RS treatment compared to FI and VS treatments suggest that RS treatment utilized the available water more efficiently. The cultivar 99OL showed higher WUE and oil yield. Thus, deficit irrigation at reproductive stage of safflower and adoption of 99OL cultivar can improve WUE and oil yield benefits under limited water conditions.

Impact of groundwater and its implications on management of water resources in western Uttar Pradesh

An attempt has been made in the paper to examine the changes in resource use structure and returns in respect of crop production activity consequent upon the implementation of important basic ingredients in the transformation of agriculture. Since irrigation and modern crop production technology are strongly complementary to each other and together result in higher production, the policy makers and farmers, therefore have started giving more emphasis to the development of groundwater irrigation and modern water extraction mechanisms. The owner category realized relatively higher returns than that of buyers category, partly due to water extraction mechanisms, owners devoted proportionately more land under high value crop like sugarcane and partly due to better accessibility and reliability of irrigation water. Moreover, without the emergence of groundwater markets, a large traction of small and marginal farmers would have been deprived from the use of irrigation, the scarcity of groundwater especially in peak period of crop production invites special attention for better management of water resource, which will ensure higher return with future sustainability of agriculture. It may be accomplished that the emergence of water markets and water transaction benefits both sellers and buyers of groundwater.

Inbreeding and purging at the genomic Level: the Chillingham cattle reveal extensive, non-random SNP heterozygosity.

Local breeds of livestock are of conservation significance as components of global biodiversity and as reservoirs of genetic variation relevant to the future sustainability of agriculture. One such rare historic breed, the Chillingham cattle of northern England, has a 350-year history of isolation and inbreeding yet shows no diminution of viability or fertility. The Chillingham cattle have not been subjected to selective breeding. It has been suggested previously that the herd has minimal genetic variation. In this study, high-density SNP genotyping with the 777K SNP chip showed that 9.1% of loci on the chip are polymorphic in the herd, compared with 62-90% seen in commercial cattle breeds. Instead of being homogeneously distributed along the genome, these loci are clustered at specific chromosomal locations. A high proportion of the Chillingham individuals examined were heterozygous at many of these polymorphic loci, suggesting that some loci are under balancing selection. Some of these frequently heterozygous loci have been implicated as sites of recessive lethal mutations in cattle. Linkage disequilibrium equal or close to 100% was found to span up to 1350 kb, and LD was above r(2) = 0.25 up to more than 5000 kb. This strong LD is consistent with the lack of polymorphic loci in the herd. The heterozygous regions in the Chillingham cattle may be the locations of genes relevant to fitness or survival, which may help elucidate the biology of local adaptation in traditional breeds and facilitate selection for such traits in commercial cattle.

Basic Outline of the Problem of the "Ageing Population of Farmers" in the Czech Republic

The problem of the ageing population of farmers is often mentioned in European discussion on the future sustainability of Agriculture and is addressed by several policy measures including those belonging to the new CAP reform. The goal of this paper is to conceptualise and empirically map the problem of ageing in the Czech Republic. Using secondary data analysis, the paper outlines the basic trends related to changes in the age structure of farmers, including the main parameters of the young and older farmers' holdings. Findings of the study suggest that the Czech Republic belongs among the group of countries which is not so much affected by the problem of ageing and that the differences between farms run by young and older farmers are not as large as in other European countries. Evaluation of the problem is partly distorted by the survey methods used by Eurostat.

Modeling changes in paddy rice sown areas in Asia

Paddy rice fields in Asia account for over 90% of global total rice cultivation area, and the major rice-producing countries of Asia account for over one-half of the world’s population. Monitoring and understanding the dynamic changes in paddy rice agriculture in Asia are very important for agricultural sustainability, food and water security, and greenhouse gas emissions. This paper presents a crop choice decision model that dynamically simulates future changes in sown areas of paddy rice in Asia. This model was developed under the framework of Action-in-Context (AiC) with the aim of understanding land users’ decisions on crop choices among a set of available alternatives using a crop utility function. Empirical validation for the model conducted after model construction indicated the reliability of the model for addressing the complexity of current agricultural land-use change and its capacity for investigating long-term scenarios in the future. Finally, the model was applied for future scenario analysis over a time frame of 30 years with 5-year increments, beginning from the year 2005. The simulation results provided insights into rates and trajectories of changes in Asian rice areas over the test period, with the resulting implications for future agricultural sustainability in Asia. These outcomes can improve understanding of projected land-use changes and explain their causes, locations and consequences, as well as providing support for land-use planning and policy making.

What influences agricultural professionals' views towards organic agriculture?

Organic agriculture is a farming system that is considered by some to have beneficial impacts on the future sustainability of agriculture. Although some research has studied the attitudes of consumers and farmers, in particular what factors influence the willingness of consumers to pay organic premiums and what factors influence farmers to adopt organic farming, no studies have considered what influences the attitudes of agricultural professionals (extension officers, scientists, academics and researchers). Given the key role that agricultural professionals play in influencing farmer adoption of agricultural innovations and conducting research, their views on farming systems may be critical for overall adoption. This study reports the results of a telephone survey conducted in 2004, with 185 agricultural professionals surveyed for their views towards organic farming. A particular aim was to study how increased knowledge and experience influenced attitudes towards organic agriculture. Using an ordered probit regression framework, some of the significant key influences on attitudes towards organic farming were: knowledge; experience; education; informational; occupational effects; and attitudes on the individual aspects of organic agriculture. The study finds support for the hypothesis that professionals with increased organic knowledge and experience are more likely to think favourably about organic agriculture.
