What Is Food Security?

Food security is a condition in which all people, at all times, have physical, social, and economic access to sufficient, safe, and nutritious food that meets their dietary needs and food preferences for an active and healthy life. This definition, established by the Food and Agriculture Organization (FAO) of the United Nations, underscores that food security is not merely about producing enough calories—it also requires consistent access, proper nutrition, and stability across seasons and years. The four pillars of food security—availability, access, utilization, and stability—demand coordinated efforts across agriculture, logistics, policy, and technology. Without attention to each pillar, even nations with high agricultural output can experience hunger due to distribution failures, economic shocks, or environmental crises.

Food insecurity is a persistent global challenge. According to the FAO’s 2023 State of Food Security and Nutrition in the World report, up to 783 million people faced hunger in 2022, and nearly one-third of the global population experienced moderate or severe food insecurity. These numbers have risen due to conflicts, climate extremes, and the lingering effects of the COVID-19 pandemic. In this context, engineering and technology play a critical role in strengthening every pillar of food security—from precision farming that boosts yields, to cold chain innovations that reduce post-harvest losses, to data systems that forecast food availability.

ASABE: A Professional Home for Food Systems Engineers

The American Society of Agricultural and Biological Engineers (ASABE) is the leading professional society for engineers and scientists who work at the intersection of agriculture, biology, and technology. Founded in 1907 as the American Society of Agricultural Engineers, ASABE now serves more than 9,000 members across the United States and over 100 countries. Its mission is to advance engineering and technology for the benefit of agriculture, food systems, and natural resources. ASABE’s work is organized around technical communities, standards development, continuing education, and public policy advocacy. Through these channels, the society systematically addresses the engineering challenges that underpin food security.

ASABE members include engineers designing irrigation systems, researchers developing autonomous harvesters, food scientists optimizing processing lines, and educators training the next generation of food systems engineers. The society’s core strength lies in bridging fundamental science with practical application—translating laboratory discoveries into scalable technologies that farmers, agribusinesses, and policymakers can adopt. This translation is essential for achieving food security at scale.

How ASABE Contributes to Food Security

ASABE contributes to food security through a multi-pronged approach: research and innovation, standards and best practices, education and professional development, advocacy, and global partnerships. Each of these activities directly addresses one or more pillars of food security.

Research and Innovation

ASABE supports a vast portfolio of research that touches every stage of the food supply chain. Key areas include:

  • Precision agriculture: Using GPS, sensors, drones, and machine learning to optimize inputs like water, fertilizer, and pesticides. Precision agriculture can increase crop yields by 10–20% while reducing environmental impact. ASABE members have developed variable-rate irrigation controllers, sensor-based nutrient management systems, and autonomous weed removal robots.
  • Irrigation and water management: Efficient water use is critical for food production. ASABE’s irrigation standards and research on drip irrigation, subsurface irrigation, and soil moisture sensing help farmers conserve water while maintaining yields. For example, the ASABE S579 standard on surface irrigation design guides engineers in creating systems that reduce runoff and deep percolation.
  • Soil health and conservation: Engineering practices such as conservation tillage, cover cropping, and contour farming are central to long-term soil fertility. ASABE’s Soil and Water Division promotes technologies that prevent erosion, improve organic matter, and enhance water infiltration.
  • Post-harvest technology: Reducing food loss after harvest is one of the most impactful ways to improve food security. ASABE members work on improved storage structures, drying systems, cold chain logistics, and food processing techniques that extend shelf life and preserve nutritional quality.
  • Bioenergy and bioproducts: By developing technologies to convert agricultural residues into energy and materials, ASABE engineers help create diversified revenue streams for farmers, reducing economic vulnerability and supporting sustainable production systems.

A concrete example is the ASABE-funded research on pollination and crop yield. Studies by ASABE members have used remote sensing to monitor bee health and create models that predict pollination deficits—enabling growers to manage pollinator habitat more effectively. Such innovations directly support the productivity pillar of food security.

Standards and Best Practices

ASABE develops and maintains hundreds of engineering standards that ensure safety, efficiency, and interoperability in agricultural and food systems. These standards cover everything from tractor roll-over protection to grain bin design to livestock waste management. For food security, ASABE standards are particularly important in post-harvest handling, food processing, and food safety. For example, ASABE S202.3 on moisture measurement in grains enables consistent quality assessment, while ASABE EPS 502 provides design guidelines for controlled environment agriculture (greenhouses and vertical farms). By harmonizing specifications, ASABE standards reduce trade barriers, facilitate global food supply chains, and help ensure that safe, nutritious food reaches consumers.

The standards development process involves rigorous peer review and consensus among engineers, industry representatives, and government agencies. ASABE also participates in international standardization through ISO technical committees, ensuring that U.S. innovations can scale globally. In an interconnected world, where food is traded across continents, these standards are a silent but powerful enabler of food security.

Education and Professional Development

ASABE offers a wide range of educational programs that equip engineers with the skills needed to tackle food security challenges. The society organizes annual international meetings (the ASABE Annual International Meeting) featuring technical sessions, workshops, and expert panels on topics such as artificial intelligence in agriculture, water scarcity, and food supply chain resilience. ASABE also provides online courses, webinars, and in-person training on subjects like precision agriculture, grain drying, and irrigation system design.

For early-career engineers, ASABE offers the AE50 Awards that recognize innovative product developments, as well as scholarships and networking opportunities. The society’s K–12 outreach programs, such as the “Engineering Design Challenge,” introduce students to agricultural and biological engineering concepts, sparking interest in food systems careers. This pipeline of talent is essential for sustaining the innovation that drives food security gains.

Moreover, ASABE publishes resources like the Guide for the Care and Use of Agricultural Animals in Research and Teaching and the Water Management and Variable-Rate Irrigation handbook. These publications serve as authoritative references for practitioners and researchers worldwide.

Advocacy and Policy Influence

ASABE engages with policymakers to promote engineering-based solutions for food security. The society submits comments on federal regulations, provides expert testimony, and participates in coalitions such as the Coalition for a Prosperous America. ASABE advocates for increased funding for agricultural research, modernization of infrastructure, and adoption of technologies that reduce environmental footprint. For instance, ASABE has actively supported the Farm Bill provisions that fund precision agriculture research and extension services. By amplifying the voice of engineers in policy discussions, ASABE helps ensure that evidence-based solutions are considered in national and global food security strategies.

Partnerships and Global Impact

ASABE collaborates with a wide network of organizations to amplify its impact on food security. Key partners include:

  • United Nations Food and Agriculture Organization (FAO): ASABE experts contribute to FAO technical guidelines on water-efficient irrigation, sustainable mechanization, and post-harvest management. These collaborations help translate global food security goals into actionable engineering practices.

The conference proceedings are a valuable repository of knowledge for engineers working in diverse climates and socioeconomic conditions.

ASABE also supports the Global Forum on Agricultural Research and Innovation, where members present engineering perspectives on land degradation, water scarcity, and climate adaptation. These partnerships ensure that engineering solutions are integrated into broader development agendas, such as the United Nations Sustainable Development Goals, especially Goal 2 (Zero Hunger).

Future Goals: AI, Robotics, and Resilient Systems

Looking ahead, ASABE is focused on integrating advanced technologies that promise to revolutionize food production while enhancing sustainability. Key areas include:

  • Artificial intelligence and machine learning: AI-powered models can predict crop yields, detect diseases, and optimize harvesting schedules. ASABE’s Big Data and AI technical committee is developing guidelines for data quality and model validation to ensure these tools are reliable and accessible to farmers.
  • Robotics and automation: From autonomous tractors to robotic fruit pickers, automation addresses labor shortages and reduces costs. ASABE is developing safety standards for agricultural robots and promoting designs that work in unstructured outdoor environments.
  • Controlled environment agriculture (CEA): Vertical farms, greenhouses, and hydroponic systems offer year-round food production with minimal land and water. ASABE’s standards for energy-efficient lighting, climate control, and nutrient delivery will help scale CEA while maintaining profitability.
  • Climate-smart agriculture: Engineers are developing carbon sequestration techniques, drought-tolerant crop varieties, and integrated pest management systems that can adapt to changing weather patterns. ASABE’s climate adaptation task force identifies engineering priorities for resilient food systems.
  • Digital twins and supply chain transparency: By creating digital replicas of farms and food processing facilities, engineers can simulate disruptions and optimize logistics. ASABE is partnering with blockchain companies to ensure traceability from field to fork, enhancing food safety and reducing waste.

ASABE’s strategic plan emphasizes three priorities: enabling a resilient food system, advancing engineering for a circular bioeconomy, and fostering a diverse and inclusive workforce. These priorities directly address the long-term challenges of food security. For example, a circular bioeconomy approach—where agricultural waste is converted into energy, feed, or materials—reduces reliance on external inputs and creates economic opportunities for rural communities.

The society also recognizes that technology alone is not sufficient. Engineering solutions must be appropriate to local contexts, affordable for small-scale farmers, and accompanied by training and support. ASABE’s Global Engineering Outreach program sends volunteer engineers to developing countries to design and implement community-based projects, such as rainwater harvesting systems and solar dryers. These initiatives embody the principles of co-creation and empowerment that are essential for lasting food security.

Conclusion: ASABE’s Enduring Role in Feeding a Growing World

As the global population approaches 10 billion by 2050, the demand for food will increase by 50–70%. Meeting this demand while staying within planetary boundaries requires unprecedented innovation in agricultural and biological engineering. The American Society of Agricultural and Biological Engineers is uniquely positioned to lead this effort. Through its research support, standards development, education programs, partnerships, and forward-looking vision, ASABE provides the technical foundation for a food-secure future.
