Top Biosecurity Threats for Farmers in 2024

Top Biosecurity Threats for Farmers in 2024

Farmers face a range of biosecurity threats that can impact crop and livestock health, economic stability, and food security. In 2024, several key biosecurity threats require attention and proactive measures to safeguard agricultural productivity and sustainability. Here, we explore the top biosecurity threats for farmers and their implications.


1. Emerging Plant Diseases


New and re-emerging plant diseases pose a significant threat to crop health and agricultural productivity. Factors such as climate change, global trade, and the movement of plant materials contribute to the spread of pathogens.



Plant diseases can lead to substantial yield losses, reduced crop quality, and increased production costs. Notable examples include the spread of Xylella fastidiosa, which affects olive trees, and wheat rust diseases.



Implementing robust plant disease surveillance and monitoring systems

Promoting the use of disease-resistant crop varieties

Educating farmers on integrated pest management (IPM) practices


2. Livestock Diseases


Diseases affecting livestock, such as African Swine Fever (ASF), Foot-and-Mouth Disease (FMD), and Avian Influenza, continue to threaten animal health and farm profitability.



Outbreaks can lead to significant animal mortality, trade restrictions, and financial losses for farmers. The impact extends to food supply chains and international trade.



Enhancing biosecurity measures on farms, including quarantine protocols and hygiene practices

Vaccination programs and veterinary support

Rapid response and containment strategies for disease outbreaks


3. Invasive Pests


Invasive pests, such as the fall armyworm and the brown marmorated stink bug, threaten crops by causing extensive damage and reducing yields. These pests spread rapidly across regions due to global trade and changing environmental conditions.



Invasive pests can devastate crops, leading to significant economic losses and increased pesticide use, which can harm beneficial insects and the environment.



Early detection and rapid response systems for pest outbreaks

Promoting biological control methods and sustainable pest management practices

International cooperation to monitor and manage pest spread


4. Bioterrorism


The intentional introduction of harmful biological agents into agricultural systems, known as bioterrorism, poses a serious threat to food security and farmer livelihoods. Potential targets include crops, livestock, and food processing facilities.



Bioterrorism can cause widespread panic, economic disruption, and long-term damage to agricultural sectors. It undermines public confidence in food safety and security.



Strengthening farm and food supply chain security

Enhancing surveillance and intelligence-sharing among government agencies and stakeholders

Developing rapid detection and response strategies for bioterrorism threats


5. Climate Change


Climate change exacerbates existing biosecurity threats by altering disease and pest distribution, increasing the frequency of extreme weather events, and stressing agricultural systems.


Farmers face increased risks of crop failure, livestock stress, and resource scarcity. Climate change also complicates efforts to manage diseases and pests, as changing conditions can create new challenges.



Adopting climate-resilient agricultural practices and crop varieties

Investing in water management and soil conservation techniques

Strengthening research on the impacts of climate change on agriculture and developing adaptive strategies


Case Study: The Impact of Fall Armyworm in Sub-Saharan Africa


Fall armyworm (Spodoptera frugiperda) is an invasive pest native to the Americas that has rapidly spread across Africa since its detection in 2016. It primarily affects maize, a staple crop in many African countries.



The infestation has led to significant crop losses, threatening food security and farmer incomes. In some regions, yield losses have exceeded 50%, exacerbating poverty and hunger.



Early Detection and Monitoring: Farmers and agricultural agencies implemented early warning systems and community-based monitoring to track the spread of fall armyworm.

Integrated Pest Management: Efforts focused on promoting IPM practices, including the use of biological controls (natural predators), cultural practices (crop rotation), and safe chemical controls.

Farmer Training: Training programs were established to educate farmers on identifying and managing fall armyworm, reducing reliance on chemical pesticides and promoting sustainable practices.



Biosecurity threats in 2024 pose significant challenges for farmers, impacting crop and livestock health, economic stability, and food security. Addressing these threats requires a comprehensive approach that includes early detection, sustainable management practices, international cooperation, and investment in research and infrastructure. By understanding and mitigating these biosecurity risks, farmers can protect their livelihoods and contribute to a more resilient agricultural system.
