Introduction The rapid increase in global population and industrial activities has led to a significant rise in organic waste generation, creating considerable environmental and public health challenges. Improperly managed organic waste serves as a major source of pollutants, including methane (CH₄) and other greenhouse gases (GHGs), which substantially contribute to climate change. Additionally, the leaching of contaminants into soil and water systems disrupt ecosystems and pose risks to human health. Conventional waste management strategies, such as landfilling and incineration, are increasingly recognized as unsustainable due to their environmental impact, including air and water pollution and inefficient resource utilization. In contrast, emerging biotechnological approaches provide sustainable solutions for waste valorization. Utilizing microbial metabolism, processes like anaerobic digestion (AD) and dark fermentation convert organic waste into bioenergy (e.g., biogas and biohydrogen) while simultaneously reducing waste volume. These bioprocesses not only optimize waste degradation but also contribute to circular economy principles by converting waste into valuable by-products, such as biofertilizers and precursors for bioplastics. This review examines recent advancements in biotechnological methods for transforming organic waste into renewable energy, highlighting their potential to address the dual challenges of waste management and sustainable energy production. Anaerobic Digestion: A Key Technology in Waste Management Anaerobic digestion is a biological process that converts organic waste into biogas, a mixture primarily composed of methane (CH₄) and carbon dioxide (CO₂)​. The process involves four main stages: Hydrolysis : Complex organic matter is broken down into simpler soluble molecules like sugars and amino acids. Acidogenesis : These simpler molecules are converted into volatile fatty acids (VFAs). Acetogenesis : VFAs are further processed into acetic acid, hydrogen, and CO₂. Methanogenesis : Finally, methanogenic archaea convert these products into methane and CO₂​. The efficiency of anaerobic digestion can be enhanced by co-digestion, where multiple types of waste are processed together. For instance, co-digesting tannery wastewater with dairy waste has been shown to improve biogas yield and methane content due to the complementary nutrient profiles of these waste streams​. Benefits of Anaerobic Digestion Energy Production : Biogas can be used to generate electricity, heat, or even upgraded to biomethane for use as a vehicle fuel​. Waste Reduction : The process significantly reduces the volume of waste, which is critical for industries with high organic waste outputs such as agriculture, food processing, and wastewater treatment​. Nutrient Recovery : The digestate, a by-product of AD, can be used as a biofertilizer, rich in nitrogen, phosphorus, and potassium, thus closing the nutrient loop. Biohydrogen Production: Novel Sustainable Waste Management process. Hydrogen, a clean fuel with zero carbon emissions, is gaining attention as a sustainable alternative to fossil fuels. Among various methods of hydrogen production, biohydrogen generated through anaerobic fermentation is particularly promising due to its low environmental impact​.  This process, known as dark fermentation, involves the microbial breakdown of carbohydrate-rich substrates in the absence of light, producing hydrogen and organic acids. Enhanced Biohydrogen Production : Research indicates that adding residual glycerol from biodiesel production to cassava wastewater can significantly boost hydrogen yield during anaerobic digestion​. The optimal conditions for maximizing hydrogen production include a balanced substrate-to-biomass ratio, temperature control, and proper inoculation with hydrogen-producing bacteria. Key Microbes : Hydrogen production is driven by specific anaerobic bacteria, including species from the genera Clostridium , Bacillus , and Enterobacter ​. Operational Parameters : Studies have shown that maintaining a pH of around 5.5 to 6.0 and a temperature of 35-38°C optimizes biohydrogen yields​. Microbial Plastic Degradation: Addressing the Plastic Pollution Crisis The accumulation of plastics in the environment is a major challenge due to their resistance to degradation. Traditional recycling methods are limited, especially for non-PET plastics like polyethylene and polystyrene​. Recent biotechnological advances focus on using microbial enzymes, such as PETase and laccases, to break down plastics into biodegradable components. Biotechnological Strategies : Enzymatic Degradation : Specific enzymes target polymer bonds, converting plastics into monomers that can be further utilized by microbes​. CRISPR and Synthetic Biology : Genetic engineering techniques, including CRISPR, are being explored to enhance the efficiency of microbial strains in breaking down plastics and converting them into valuable biochemicals​. Plastic degradation under aerobic conditions The Role of Biogas and Biohydrogen in the Circular Economy Integrating biotechnological solutions into waste management systems aligns with the principles of the circular economy. By converting waste into bioenergy, industries can reduce their carbon footprint, lower waste management costs, and contribute to energy sustainability​. Key Applications : Decentralized Waste Management : Small-scale anaerobic digesters can be implemented in communities to process organic waste, generating biogas for local energy needs while reducing landfill dependence​. Industrial Waste Valorization : Food processing industries, breweries, and dairy farms can adopt biohydrogen and biogas production to manage their organic waste streams effectively. Various methods of obtaining biogas and biohydrogen via fermentatio Conclusion The transition to sustainable waste management requires innovative approaches that integrate biotechnological advancements. Technologies like anaerobic digestion and biohydrogen production not only offer solutions to waste management but also pave the way for sustainable energy production. By embracing these technologies, industries can play a pivotal role in achieving environmental sustainability and reducing reliance on fossil fuels​. Moving forward, continued research and investment in optimizing microbial processes and scaling up these technologies will be crucial to realizing their full potential.

Hemp harvesting on the banks of Rhine river, 1860s Cannabis ( Cannabis sativa ) has a documented history of cultivation that extends over thousands of years, with evidence dating back to at least the Neolithic era. Initially domesticated in Eastern Asia, cannabis became a significant part of human culture due to its adaptability and multitude of uses, including fiber production, medicinal applications, and food sources.  The spread of cannabis across continents was influenced by human migrations and trade, integrating deeply with agricultural practices across Europe, Asia, and Africa. Throughout its long history, cannabis has co-evolved with the natural environment, forming mutually beneficial relationships with organisms such as mycorrhizal fungi and Plant Growth-Promoting Rhizobacteria (PGPR).  Hemp plant illustration from a botanical atlas, 19th century Europe Co-Evolution with Mycorrhizal Fungi   One of the most remarkable aspects of cannabis’s evolutionary history is its symbiosis with mycorrhizal fungi. These fungi are symbiotic with most terrestrial plants, forming associations that extend root networks and enhance the plant's ability to access water and essential nutrients in exchange for carbohydrates produced by plants.   Rhizophagus irregularis ( Glomus intraradices) a species of arbuscular mycorrhizal fungi (AMF), is known to form extensive hyphal networks that connect with cannabis roots, facilitating increased absorption of phosphorus and other minerals that are often limited in soil. Pseudomonas spp. in the rhizosphere and its' influence for cannabis plant growth The process by which AMF enhances nutrient uptake involves the fungi penetrating the root cells and forming arbuscules—structures that facilitate the exchange of nutrients between the plant and the fungus. The plant supplies the fungi with carbon derived from photosynthesis, while the fungi provide the plant with improved access to phosphorus, nitrogen, and micronutrients. This relationship is particularly valuable in cannabis cultivation, where phosphorus is essential for robust growth and flowering. Studies have shown that cannabis plants with AMF associations exhibit better root mass, increased growth rates, and enhanced resilience to environmental stressors​. The Role of Trichoderma and Beneficial Bacteria   Trichoderma harzianum in cannabis rhizosphere In addition to mycorrhizal fungi, Trichoderma harzianum  plays an integral role in promoting cannabis health. This beneficial fungus colonises the rhizosphere, producing growth hormones such as indole-3-acetic acid (IAA), which stimulate root branching and elongation. The result is a more extensive root system capable of greater nutrient and water absorption. Furthermore, Trichoderma  acts as a natural biocontrol agent by releasing lytic enzymes and secondary metabolites that deter soil-borne pathogens, thereby reducing disease incidence and promoting overall plant vitality. Benefits of a healthy and diverse rhizosphere Beneficial bacteria, particularly strains of Bacillus  and Lactobacillus , add another layer of support to cannabis cultivation: Nutrient Solubilization :  Bacillus subtilis  and related strains enhance the availability of phosphorus and potassium in the soil, making these nutrients more accessible to the plant. This solubilization process is essential for cannabis, which requires ample nutrients for vigorous growth and development. Pathogen Suppression :  Bacillus  spp. produce bioactive lipopeptides and enzymes that protect the plant from fungal pathogens, reinforcing the plant’s ability to withstand biotic stress. Soil Fertility Enhancement :   Lactobacillus  spp., such as L. casei  and L. plantarum , contribute to the breakdown of organic matter and nutrient cycling, enriching soil fertility and ensuring that cannabis plants have a consistent supply of essential nutrients throughout their growth cycle​. Historical and Ecological Significance   Cannabis’s extensive use throughout history also intersected with traditional agricultural practices that leveraged the plant’s resilience and diverse applications. For example, hemp retting, a process used to extract fibers from cannabis stems by submerging them in water, has been practiced for centuries. Historical sediment analyses in places like the French Massif Central have revealed the presence of cannabinol (CBN), a phytocannabinoid metabolite, in ancient sediments. This finding underscores the deep connection between human activity and cannabis cultivation over centuries​. Retting, although beneficial for producing high-quality fibers, has historically posed environmental challenges by affecting water quality. This highlights the importance of modern, sustainable practices that maintain productivity while protecting natural resources. The use of microbial inoculants such as AMF , Trichoderma , and beneficial bacteria supports sustainable agricultural systems by enhancing soil health, reducing dependency on chemical fertilisers, and improving carbon capture. Modern Applications: The Role of Microbial Products   The co-evolution of cannabis with beneficial microbes provides a strong foundation for modern microbial technologies aimed at sustainable cultivation. Our Super Microbes brand, with products like RootX and BoostX incorporates these naturally occurring relationships backed by science and research : RootX :  Integrates Glomus intraradices , Trichoderma harzianum , and 13 species of Bacillus  to extend root systems, optimize nutrient absorption, and offer natural protection against pathogens. This synergy helps cannabis plants achieve vigorous growth and enhanced yield. BoostX :  Focuses on enriching the microbial environment with multiple strains of Bacillus , Lactobacillus , Rhodopseudomonas palustris , and Saccharomyces cerevisiae . These components increase nutrient bioavailability, promote robust flowering and bud formation, and contribute to sustained soil health. Environmental Benefits and Carbon Sequestration   The integration of mycorrhizal fungi and beneficial bacteria into cannabis cultivation also plays a significant role in climate resilience. Mycorrhizal networks contribute to soil carbon storage by stabilizing organic matter and forming stable carbon pools as their structures decompose. The allocation of 5-20% of carbon captured by plants to support mycorrhizal fungi showcases their vital role in the carbon cycle. Estimates indicate that mycorrhizal fungi contribute to sequestering approximately 13 Gt of CO2e annually, a significant portion of the global carbon output​.. Conclusion   The symbiosis between cannabis and organisms like mycorrhizal fungi and beneficial bacteria is just a small example of nature's complexity and adaptability. Understanding and harnessing these relationships not only improve plant health and yield but also foster sustainable agricultural practices that contribute to soil health and carbon capture. The continued study and application of these beneficial interactions can support ecological restoration efforts and bolster climate-positive outcomes, paving the way for a more resilient and sustainable agricultural future.

Mycorrhizal fungi, symbiotic partners of most terrestrial plants, play a crucial role in global carbon cycling. By forming intricate relationships with plant roots, these fungi facilitate the transfer and storage of carbon in soil ecosystems. This text explores the mechanisms by which mycorrhizal fungi contribute to carbon sequestration, their ecological importance, and the potential implications for climate change mitigation. Carbon Fixation in Plants Carbon fixation is a critical process in photosynthesis, where plants convert atmospheric carbon dioxide (CO2) into organic compounds. This process is fundamental to the growth of plants and the sustenance of life on Earth. It primarily occurs in the chloroplasts of plant cells, utilizing light energy to drive the conversion of CO2 and water into glucose and oxygen. The most well-known pathway for carbon fixation is the Calvin Cycle, which takes place in the stroma of chloroplasts. The cycle begins when CO2 is attached to a five-carbon sugar, ribulose-1,5-bisphosphate (RuBP), by the enzyme RuBisCO. This reaction produces a six-carbon compound that immediately splits into two molecules of 3-phosphoglycerate (3-PGA). These molecules undergo a series of reactions using energy from ATP and NADPH, generated in the light-dependent reactions of photosynthesis, to form glyceraldehyde-3-phosphate (G3P). G3P is then used to synthesize glucose and other carbohydrates, which serve as energy sources and structural components for the plant. Carbon fixation is not only vital for plant growth but also for the global carbon cycle. Through photosynthesis, plants act as carbon sinks, sequestering atmospheric CO2 and mitigating the effects of climate change. Additionally, the organic compounds produced via carbon fixation form the base of the food chain, supporting a wide range of organisms, from herbivores to apex predators. In summary, carbon fixation in plants is an essential biochemical process that sustains life on Earth by converting CO2 into usable organic matter, thereby supporting plant growth and contributing to the global carbon balance. Plants allocate enough carbon to underground mycorrhizal fungi equivalent to roughly one-third of carbon emitted yearly by fossil fuels Peer-Reviewed Publication CELL PRESS ”  Carbon Flow to Mycorrhizal Mycelia Mycorrhizal fungi receive a significant portion of carbon fixed by plants through photosynthesis. Estimates suggest that plants allocate between 5-20% of their total carbon uptake to these fungi. This carbon is used to build and maintain extensive mycelial networks, which can transport and store carbon in the soil​​. Mechanisms of Carbon Storage Mycorrhizal fungi contribute to soil carbon storage through several mechanisms. First, they enhance the formation of soil aggregates by exuding compounds such as glomalin, which binds soil particles together, thereby stabilizing soil organic matter. Additionally, the mycelial networks themselves become part of the soil organic matter when they die and decompose, forming a stable carbon pool known as fungal necromass​​. VIDEO: FLOWS OF FLUORESCENTLY LABELED CARBON INSIDE MYCORRHIZAL FUNGI CREDIT: CARGILL & OYARTE-GALVEZ (AMOLF) Ecological Importance Enhancing Soil Health Mycorrhizal fungi improve soil structure and fertility, which in turn enhances plant growth and resilience. The hyphal networks increase the surface area for nutrient exchange, allowing plants to access nutrients that are otherwise unavailable. This is particularly important in nutrient-poor soils, where mycorrhizal fungi can significantly boost plant productivity and health​​. Biodiversity and Ecosystem Stability Mycorrhizal associations support plant diversity and ecosystem stability. By facilitating nutrient uptake, these fungi help a wide variety of plant species to thrive, thereby maintaining biodiversity. Furthermore, the carbon storage function of mycorrhizal fungi contributes to the overall stability and resilience of ecosystems, making them less susceptible to disturbances such as climate change​​. Applications in Climate Change Mitigation Carbon Sequestration Potential The global contribution of mycorrhizal fungi to carbon sequestration is substantial. Studies estimate that these fungi are responsible for sequestering approximately  13 Gt of CO2e per year, which is equivalent to about 36% of annual CO2 emissions from fossil fuels. This highlights the potential of mycorrhizal fungi in mitigating climate change through enhanced carbon sequestration​​. Sustainable Agriculture In agriculture, the use of mycorrhizal fungi can reduce the need for chemical fertilizers and pesticides, promoting more sustainable farming practices. By improving nutrient uptake and soil health, mycorrhizal fungi help to increase crop yields and quality, particularly in low-fertility soils. This can lead to a reduction in the environmental impact of agriculture and support global food security​​. Conclusion Mycorrhizal fungi are vital components of terrestrial ecosystems, playing a key role in carbon sequestration and soil health. Their symbiotic relationships with plants have profound implications for global carbon cycling and climate change mitigation. By enhancing our understanding and application of these fungi, we can unlock their full potential to support sustainable agriculture and environmental restoration, contributing to a more sustainable future.

In the continuously evolving field of agriculture and horticulture, the search for sustainable and effective plant growth enhancers remains a crucial priority. Among the promising biological agents gaining recognition is Saccharomyces cerevisiae (commonly known as baker’s yeast). Traditionally associated with baking and brewing, S. cerevisiae has garnered considerable attention for its potential applications in promoting plant growth and enhancing soil health. This review explores the mechanisms, benefits, and applications of S. cerevisiae in agriculture, providing an in-depth look at how this microorganism can contribute to sustainable farming practices. seedling development study What is Saccharomyces cerevisiae? Saccharomyces cerevisiae is a single-celled eukaryotic yeast that has been integral to food production for millennia. Its role in bread fermentation and alcohol production is well-established, but recent research has uncovered its multifaceted applications in agriculture, particularly as a plant growth promoter and a biological control agent. With its ability to ferment sugars, S. cerevisiae produces essential byproducts such as ethanol and carbon dioxide, which are beneficial in agricultural applications (Shalaby & El-Nady, 2008; Ballet et al., 2023). Mechanisms of Action in Agriculture Saccharomyces cerevisiae functions through several biological mechanisms that promote plant health and growth: Nutrient Availability: This yeast enhances the decomposition of organic matter, releasing key nutrients such as nitrogen, phosphorus, and potassium in forms readily available for plant uptake. The decomposition process leads to improved soil fertility and nutrient cycling (Shalaby & El-Nady, 2008). Plant Hormone Production: S. cerevisiae produces growth-promoting hormones, including auxins and gibberellins, which significantly enhance root and shoot development (Ballet et al., 2023). Phosphorus Mobilising: Phosphorus is often a limiting nutrient in soils due to its low solubility, making it unavailable to plants. Strains of S. cerevisiae and other yeasts, such as those isolated from Spanish vineyards, have been shown to solubilize phosphates by producing organic acids that release phosphorus from insoluble compounds. This enhanced phosphate availability significantly boosts plant growth by making this critical nutrient accessible for root uptake. S. cerevisiae Sc-6 and other strains from vineyards demonstrated this trait, showing high phosphate solubilization efficiency in experimental trials (Fernandez-San Millan et al., 2020). Disease Suppression: By competing with harmful soil-borne pathogens such as Fusarium oxysporum, S. cerevisiae has shown the ability to reduce disease incidence through both competition and the production of antimicrobial compounds (Shalaby & El-Nady, 2008; Ahmed et al., 2010). Stress Tolerance: Research indicates that S. cerevisiae helps plants cope with abiotic stresses such as drought and salinity by modulating stress response pathways, thus improving plant resilience under adverse environmental conditions (Ahmed et al., 2010). Benefits of Saccharomyces cerevisiae for Plants Enhanced Phosphorous mobilising Studies have consistently demonstrated the positive impact of S. cerevisiae on plant growth and yield. For instance, when used as a seed treatment or foliar spray, S. cerevisiae has been shown to improve root development, biomass accumulation, and overall crop yield. This is primarily attributed to its role in increasing nutrient availability and enhancing hormone production (Shalaby & El-Nady, 2008). Additionally, studies from Spanish vineyards have shown that S. cerevisiae can enhance seedling development, indicating a direct yeast-plant interaction that leads to increased root biomass and chlorophyll content in maize and lettuce (Fernandez-San Millan et al., 2020). Improved Soil Health Saccharomyces cerevisiae contributes to soil health by enhancing microbial diversity and improving soil structure. By breaking down organic matter, it promotes better water retention and soil aeration, creating a conducive environment for plant growth. Furthermore, the yeast's involvement in nutrient cycling helps reduce the need for chemical fertilizers, promoting sustainable agriculture (Ballet et al., 2023). Disease Resistance One of the most notable benefits of S. cerevisiae is its ability to protect plants from diseases. By inhibiting the growth of pathogens such as Fusarium oxysporum, it significantly reduces the prevalence of soil-borne diseases. This biocontrol capacity has been extensively studied, with research confirming its efficacy in crops such as sugar beet and cucumber (Shalaby & El-Nady, 2008; Ahmed et al., 2010). Stress Tolerance In addition to enhancing growth and disease resistance, S. cerevisiae helps plants tolerate abiotic stresses. Studies on crops like wheat have shown that yeast-treated plants maintain better water content and photosynthetic efficiency during periods of drought and salinity, resulting in improved growth under stressful conditions (Ballet et al., 2023). Practical Applications in Agriculture Seed Treatment Coating seeds with a S. cerevisiae suspension has been shown to enhance germination rates and early seedling growth. In sugar beet, for example, yeast-treated seeds demonstrated significantly higher germination rates compared to untreated controls, indicating the potential of S. cerevisiae as an effective seed treatment agent (Shalaby & El-Nady, 2008). Studies from vineyards have shown similar enhancements in maize and lettuce, where yeast treatments increased root biomass and shoot development (Fernandez-San Millan et al., 2020). Soil Amendment Incorporating S. cerevisiae into soil via compost or yeast suspensions can improve soil fertility and microbial activity. The yeast’s ability to decompose organic matter enhances nutrient availability and promotes soil structure improvement (Ahmed et al., 2010). Foliar Spray Foliar applications of S. cerevisiae can enhance nutrient uptake and improve plant immunity. Studies suggest that spraying a yeast solution on leaves can increase photosynthesis rates and help address nutrient deficiencies (Ballet et al., 2023). Compost Enhancement When added to compost, S. cerevisiae accelerates the decomposition process, resulting in nutrient-rich compost that supports soil fertility and plant health (Ballet et al., 2023). Phosphorus mobilising Saccharomyces cerevisiae effectivety in phosphorus mobilising is done by solubilizing insoluble phosphate compounds, making this nutrient more available to plants. This property enhances root development and supports sustainable agriculture, particularly in phosphorus-deficient soils (Fernandez-San Millan et al., 2020). Research Highlights Improved Tomato Yield In a study focusing on tomato plants, seeds treated with S. cerevisiae exhibited better root development, higher biomass, and increased fruit yield. The study concluded that the yeast’s ability to enhance nutrient availability and hormone production was responsible for these improvements (Shalaby & El-Nady, 2008). Disease Suppression in Cucumber Saccharomyces cerevisiae has also been demonstrated to suppress diseases such as powdery mildew in cucumber plants, reducing the incidence of infection and improving overall plant health (Shalaby & El-Nady, 2008). Seedling Development in Vineyards Research on vineyard yeasts has demonstrated the positive impact of S. cerevisiae and other yeast strains on seedling development. For example, S. cerevisiae Sc-6 and Debaryomyces hansenii Dh-67 enhanced the dry weight and chlorophyll content in maize seedlings by up to 10% (Fernandez-San Millan et al., 2020). These findings suggest that vineyard yeasts, including S. cerevisiae, could be valuable tools in sustainable agricultural practices. Conclusion Saccharomyces cerevisiae is a versatile microorganism with numerous applications in agriculture, ranging from enhancing plant growth to protecting crops from diseases. Its ability to improve nutrient availability, produce growth-promoting hormones, solubilize phosphates, and help plants withstand abiotic stresses positions it as a valuable tool in sustainable agriculture. As research continues to unveil its potential, S. cerevisiae is poised to play an increasingly important role in promoting sustainable farming practices and improving food security. By integrating S. cerevisiae into agricultural systems, farmers and gardeners alike can achieve healthier, more productive plants while reducing the reliance on chemical inputs. This aligns with global efforts to promote sustainable development and environmental stewardship (Ballet et al., 2023). References:Ahmed, A. S., Hamdan, S., Annaluru, N., Watanabe, S., Rahman, M.

Ending hunger for everyone in the world by the year 2030 is the second Sustainable Development Goal (SDG) of the United Nations. A goal that would seem to belong to the realm of utopian thinking just a hundred years ago is nowadays considered feasible, with the share of the global population living in hunger having declined from 13,4% in 2001 to 8,8% in 2017. Similarly, the share of underweight children went from a concerning 20,5% of all the world's children in the year 2000 to a reduced, yet still important 12,6% by 2020. The world seems to be closing in on hunger, slowly but surely. Yet, in spite of this apparent chain towards success, the United Nations is sounding the alarm: the world is not on track towards reaching the goal of zero hunger by 2030. In point of fact, the recent tendency is toward a reversion of the trends of hunger: more people could end up hungry by the year where hunger should have ended than by the beginning of the century, with 840 million hungry people in the world being a very real possibility. What drives these changes? What can reverse decades of improvement and successes in the battle against hunger? The greatest threat against what has already been achieved is, put simply, food insecurity: a great share of the world's population lives in areas where the major drivers of hunger already cause, or can cause in the future, a heavy impact. Conflict stands as the main cause behind 60% of the world's hunger, with climate change, inequality, and the current COVID-19 pandemic affecting every single country around the world in turn. The major concerns in all these cases are two: logistics and production. The world already produces more than enough food for everyone currently living in it, but this food is distributed poorly, unequally, and inefficiently. These systems of distribution can, in turn, be easily disrupted, as shortages caused by COVID-19 proved very quickly and very clearly in the year 2020. If production itself is disrupted or stopped by climatic phenomena (enter climate change and its droughts, floods, sandstorms, and fires), it is difficult to predict how many people could become hungry and how quickly this could happen. All in all, the goal of ending hunger could seem to be farther away than ever. A solution that policymakers need to focus on in order to tackle this is smallholder farming. Smallholders, the owners of farms of less than two hectares, comprise the vast majority of all farmers around the world, are impressively efficient at producing 35% of our food in just 12% of the land used for agriculture (larger farms, in contrast, produce the other 65% while occupying 88% of the cultivated land), are often local and thus can supply food to their communities in situations of supply chain disruption, are more willing to adopt new and better approaches to land stewardship, and help mitigate income inequality among farmers. Yet most policymakers do not focus on helping these smallholders survive and thrive, and neither does the current flow of research from academics and publishers. An article published in 2020 in the journal Nature found that over 95% of the articles published on agricultural subjects are irrelevant to the needs of smallholder farmers, and focus in turn on the needs of larger, wealthier farms. Most of the studies reviewed didn't even involve the participation of farmers, at all. It is clear that if we're going to beat, or at the very least stave hunger by 2030, policymakers (and researchers as well) need to stop getting this wrong about ending hunger: smaller farms are not quaint remnants of a pre-industrial past. They, their survival and proliferation, might be what makes our food systems reliable in the face of many looming dangers. Two women tend to their land in a 1.6 hectare (4-acre) land in Machakos, Kenya.

The desirability of carbon-rich soil is a no-brainer for anybody engaged in agriculture and other land-based forms of food production. The fact that carbon is volatilized practices such as tilling the soil is less known, but well-documented in the literature, with millions of tons of carbon dioxide (CO2) being released into the atmosphere through the action of microbes that turn the carbon, present in the soil as organic matter, into its gaseous form. This is why, for example, simply adopting no-tillage practices could reduce by a whopping 30% the greenhouse gas emissions of the agricultural sector. That might not sound like much at first sight, considering that agriculture is not the major contributor to anthropogenic climate change, but its meaning is more evident when considering it this way: changing a single, non-essential technique could bring down the emissions from an entire economic sector by one third. That is just one of many examples of what carbon farming can do when it becomes a conscious agricultural goal. In light of the environmental benefits to be drawn from adopting carbon-farming strategies, the question arises of where organic agriculture stands in the face of the environmental responsibility of the whole agricultural industry. Organic agriculture is sustained on principles such as ecology and care, and, as such, organic farms conduct their activities on a wider range of values that allow them to explore and integrate newer, innovative practices with more ease. Organic farmers also understand better the interrelated nature of beneficial practices, and are more willing to put them into action — particularly women of educated backgrounds. Based on this, there’s the question of whether organic growers should target carbon farming as their next main concern. It is evident that organic farming is expanding nowadays from being a purely non-chemical fertilization scheme into a set of practices, cultural references, values and social networks that aim to farm sustainably the world’s soils. By exploring techniques and practices for carbon-farming such as agroforestry and crop diversification, organic farmers can, at the same time, expand the biodiversity of their lands (already a major benefit of organic agriculture, with its consequent effect in ecosystem resilience and the pest resistance of crops), organic farmers could potentially be introducing changes that are economically very sound and that, at the same time, benefit the world and increase the strength of their agricultural operations. The question appears, then: in the ideally diversified crop scheme of an organic farm, shouldn’t carbon be, indeed, considered the next organic crop? Cotton and pine growing in an alley cropping system, an agroforestry practice that can help retain and absorb carbon into agricultural soils.

Bionematicides are a class of biological agents, primarily composed of fungi and bacteria, employed to control plant-parasitic nematodes . These nematodes are microscopic organisms that infest plant roots, causing significant damage to crop health and yields, with estimated annual losses reaching $215.77 billion globally for major crops . The increasing awareness of the environmental and health hazards posed by chemical nematicides has accelerated interest in bionematicides as sustainable alternatives. What Are Bionematicides and how they help to control root knot nematodes? Bionematicides are beneficial fungi, bacteria , and natural microbial metabolites that suppress nematode populations in the soil. Unlike synthetic chemicals, these biological agents work naturally and selectively  to manage plant-parasitic nematodes without harming beneficial soil organisms.Key microorganisms include: Nematophagous fungi  (e.g., Paecilomyces lilacinus , Pochonia chlamydosporia ) Beneficial bacteria  (e.g., Bacillus thuringiensis , Serratia marcescens ) Nematode-trapping fungi  that actively predate  or parasitize nematodes. Research Highlight : Studies confirm that bacterial strains such as Pseudomonas fluorescens  and Bacillus thuringiensis  show exceptional nematicidal activity, reducing root-knot nematode ( Meloidogyne spp. ) populations by up to 90%​​.   Applied Microbiology and Biotechnology 101(7) DOI:10.1007/s00253-017-8175-y Why Are Bionematicides the Future of Biological Nematode Control? Bionematicides are emerging as the cornerstone of sustainable nematode management, providing effective control while addressing the environmental and economic challenges posed by chemical nematicides. Here are the key reasons for their growing prominence: 1. Environmental Safety Non-Toxic to Beneficial Organisms : Unlike chemical nematicides, bionematicides are safe for non-target organisms such as earthworms, pollinators, and other beneficial soil microbes, preserving ecosystem balance. Reduced Environmental Contamination : Their biodegradable nature minimizes soil and water pollution, addressing concerns of toxic residues in agricultural produce and the environment. Climate Resilience : Bionematicides align with climate-smart agriculture by reducing the carbon footprint associated with the production and application of synthetic chemicals. 2. Soil Health Enhancement Biodiversity Restoration : Bionematicides enhance soil microbial diversity and foster nutrient cycling, reversing the degradation caused by prolonged chemical use. Improved Soil Structure : They contribute to better soil aeration and water retention by promoting microbial activity and reducing compaction. Natural Nematode Suppression : By fostering microbial antagonism, bionematicides enable soils to naturally suppress nematode populations over time, reducing dependency on external inputs. Sustainability in Agriculture Eco-Friendly Solutions : By reducing chemical inputs, bionematicides support eco-friendly farming practices and contribute to sustainable pest management. Cost-Effectiveness : Their ability to be integrated with existing agricultural practices, such as organic amendments, minimizes costs while enhancing yield. Consumer Demand : With growing consumer preference for chemical-free and organic produce, bionematicides position farmers to meet market expectations while maintaining profitability. 5. Innovation-Driven Growth Advancements in Biotechnology : Improvements in microbial formulation, mass production, and shelf-life are making bionematicides more accessible and user-friendly. Integration with Precision Agriculture : Bionematicides are being integrated into precision farming tools, allowing for targeted applications that maximize efficacy and minimize waste. How Do Bionematicides Work? Bionematicides employ a range of biological mechanisms to effectively manage plant-parasitic nematodes (PPNs), targeting their lifecycle stages while enhancing plant and soil health. These mechanisms include predation, parasitism, antagonism, and induction of systemic plant resistance. Below is a detailed explanation of each mechanism: 1. Predation Mechanism : Predatory nematophagous fungi actively hunt and consume nematodes by trapping or immobilizing them through specialized structures such as adhesive networks or constricting rings. Example : Paecilomyces lilacinus  is a notable predator that targets nematode eggs and juveniles. It forms a dense mycelial network around nematode eggs, secreting enzymes that dissolve the protective egg shells, allowing the fungus to feed on the contents. Similarly, Arthrobotrys spp.  utilize sticky traps or loops to ensnare nematodes before digesting them. Impact : Predation directly reduces nematode populations in the soil, limiting their ability to infest plants. 2. Parasitism Mechanism : Parasitic fungi and bacteria infect nematodes by attaching to their body surfaces or penetrating their natural openings (e.g., stylets, vulva). Once inside, these microbes release a combination of enzymes, toxins, and metabolites to suppress nematode development and reproduction. Example : Pochonia chlamydosporia  is an egg-parasitic fungus that colonizes nematode eggs. It uses specialized structures called appressoria to adhere to the eggshell, penetrates it, and produces lytic enzymes like chitinase and protease that degrade the egg, preventing hatching. Pasteuria penetrans , a parasitic bacterium, attaches its spores to the nematode's cuticle. The spores germinate, forming a germ tube that invades the nematode's body, eventually filling it with bacterial endospores and killing it. Impact : Parasitism reduces the reproductive success of nematodes and disrupts their lifecycle, leading to population decline over time. 3. Antagonism Mechanism : Beneficial microbes outcompete nematodes by occupying the same ecological niche in the rhizosphere. These microbes secrete nematicidal compounds, disrupt nematode signaling, and alter the soil environment to make it inhospitable for nematodes. Example : Serratia marcescens  produces protease enzymes and toxins that break down nematode cuticles and inhibit their mobility and feeding. Pseudomonas fluorescens  releases secondary metabolites such as hydrogen cyanide (HCN), phenazines, and 2,4-diacetylphloroglucinol (DAPG) that disrupt nematode development and behavior. Impact : Antagonistic interactions help suppress nematode populations indirectly by creating a competitive and hostile environment, reducing nematode survival and activity. 4. Induced Plant Resistance Mechanism : Certain bionematicides stimulate the plant's natural defense mechanisms, a process known as induced systemic resistance (ISR). This involves activating signaling pathways (e.g., salicylic acid, jasmonic acid) that strengthen the plant's immune response against nematode attacks. Example : Aspergillus niger  and Trichoderma harzianum  enhance the production of plant defense enzymes such as peroxidases and chitinases. These enzymes fortify the plant cell walls, making it harder for nematodes to penetrate and establish feeding sites. Bacillus subtilis  can prime plants for a stronger and quicker defense response, reducing nematode-induced damage. Impact : Induced resistance enhances the plant's resilience against nematodes, reducing the severity of infestations and mitigating yield losses. REVIEW article Front. Microbiol. , 25 May 2020 Sec. Plant Pathogen Interactions Volume 11 - 2020 | https://doi.org/10.3389/fmicb.2020.00992 Synergistic Impact When combined in Integrated Nematode Management (INM) programs, these mechanisms offer robust and sustainable control of nematodes. For example, the use of parasitic fungi with predatory microbes can simultaneously target different lifecycle stages of nematodes, while induced plant resistance can further bolster plant defenses. This multi-pronged approach not only reduces nematode populations but also improves soil health and crop productivity, positioning bionematicides as a cornerstone of sustainable agriculture Integrated Nematode Management Strategies Bionematicides are most effective when integrated into a broader nematode management system, including: Crop Rotation : Alternating host and non-host crops reduces nematode buildup. Soil Amendments : Organic matter and beneficial microorganisms improve soil structure and nematode suppression. Resistant Cultivars : Incorporating nematode-resistant crop varieties.
