IAEA Launches Global Research Initiative to Combat Rapid Spread of Crop Diseases Threatening Food Security

The International Atomic Energy Agency (IAEA) has launched a major global research initiative to tackle the accelerating spread of transboundary crop diseases, warning that climate change, global trade, and the movement of infected planting materials are driving unprecedented risks to food security and agricultural livelihoods.

The five-year Coordinated Research Project (CRP), led through the Joint FAO/IAEA Centre of Nuclear Techniques in Food and Agriculture, aims to equip countries with advanced tools to detect, monitor, and manage plant diseases that threaten staple crops such as wheat, potato, and cassava.

Growing Threat to Global Food Systems

Transboundary plant diseases—capable of spreading rapidly across regions and continents—are becoming increasingly difficult to control.

Major threats highlighted include:

• Wheat blast

• Potato late blight

• Potato bacterial wilt

• Cassava witches' broom disease

These pathogens can cause devastating crop losses once established, often overwhelming national plant protection systems and disrupting food supply chains.

The challenge is compounded by latent infections, which can remain undetected until diseases are already widespread, making early intervention difficult.

With shifting climate patterns and expanding global trade networks, the risk of faster and wider disease transmission is expected to grow significantly in the coming years.

Nuclear Science at the Forefront of Detection and Control

The IAEA's new initiative leverages nuclear and related biotechnologies to strengthen plant health systems, offering innovative solutions that complement conventional agricultural practices.

Key technologies include:

• Irradiation techniques (gamma rays, X-rays, electron beams) to develop beneficial microorganisms that suppress plant pathogens

• Molecular diagnostics for early and precise disease detection

• Field-deployable detection tools for rapid response in affected areas

• Hyperspectral and near-infrared imaging for high-throughput crop monitoring and disease identification

These tools enable earlier detection, more accurate surveillance, and more sustainable disease management strategies, reducing reliance on chemical pesticides.

Strengthening Early Detection and Preparedness

A central goal of the CRP is to improve early warning systems, allowing countries to identify and respond to outbreaks before they escalate.

The project will focus on:

• Developing low-cost diagnostic tools accessible to resource-constrained regions

• Standardising early detection protocols for priority pathogens

• Enhancing high-throughput phenotyping to identify disease-resistant crop varieties

• Accelerating breeding programmes through mutation induction and rapid generation advancement

By integrating these approaches, the initiative aims to build more resilient agricultural systems capable of withstanding emerging threats.

Global Collaboration and Knowledge Sharing

The CRP will bring together scientists, research institutions, and plant protection authorities from around the world, fostering collaboration and knowledge exchange.

Participating countries will work to:

• Harmonise monitoring systems and methodologies

• Share diagnostic data and reference materials

• Develop adaptable solutions tailored to different agro-ecological contexts

Capacity-building activities—including research coordination meetings and technical training—will support the development of expertise in areas such as molecular diagnostics, digital phenotyping, and biological control.

Toward Sustainable Disease Management

In addition to detection, the initiative emphasises sustainable control strategies, including the use of nuclear-enabled biological solutions that reduce dependence on chemical inputs and support the production of clean planting materials.

This integrated approach aligns with broader global efforts to promote environmentally sustainable agriculture while safeguarding food production.

Opportunities for Global Participation

The project will support up to 10 research contracts and five research agreements, offering opportunities for institutions worldwide to contribute to the development of innovative plant health solutions.

Research organisations have until 10 May 2026 to submit proposals, with the IAEA encouraging participation from women and early-career researchers to strengthen diversity and capacity in the field.

A Critical Step for Food Security

As global food systems face increasing pressure from climate change, pests, and disease outbreaks, the IAEA's initiative represents a proactive effort to strengthen preparedness and resilience.

By combining cutting-edge science with international collaboration, the project aims to protect staple crops, safeguard farmer livelihoods, and ensure stable food supplies for millions of people worldwide.
