In a world where climate change and invasive species threaten global food security, a once-modest scientific information service has become a vital shield for farmers worldwide.
Imagine a world where a tiny insect, unseen and undetected, can travel across continents and devastate an entire country's staple crop. Or where a resilient weed, accidentally introduced, chokes out native species and cripples local agriculture. This is the daily reality of our interconnected planet. For over a century, one organization has been at the forefront of the scientific battle against these threats. What began as a single entomological committee has grown into CAB International (CABI), a nonprofit intergovernmental organization dedicated to solving problems in agriculture and the environment for some of the world's most vulnerable communities 1 .
The story of the Commonwealth Agricultural Bureaux is a story of scientific adaptation on a global scale. Its origins date back to 1910, with the formation of the Entomological Research Committee (Tropical Africa), tasked with fighting "one of the enemies of mankind"—the devastating impact of pests and diseases 3 . Its mission was straightforward: post field entomologists in Africa to collect and study harmful insects, sending specimens to the British Museum for identification.
This humble beginning rapidly expanded. The Imperial Bureau of Entomology was formed in 1913, followed by the Imperial Bureau of Mycology in 1920 3 . Their functions were twofold: identifying pests and diseases, and creating abstract journals to summarize global scientific literature for researchers and policymakers. This established a core principle that would define the organization for the next century: the curation and dissemination of scientific knowledge is as crucial as the research itself.
A pivotal moment came in 1927 with the Imperial Agricultural Research Conference, which agreed to form a network of new bureaux, each producing its own abstract journal 3 . This led to the official formation of the Imperial Agricultural Bureaux in 1930, which later became the Commonwealth Agricultural Bureaux (CAB) in 1947 3 . For decades, CAB served as a centralized hub for agricultural knowledge, building a renowned database that would eventually become the 10-million-record-strong CAB Abstracts 1 3 .
The transformation into the modern CAB International in 1986 marked a strategic shift from a Commonwealth-focused information provider to a global, development-led organization 1 3 . Today, CABI is supported by 48 member countries and a diverse group of donors, including the UK's Foreign Office and the European Union 1 . Its mission—"improving people's lives worldwide by solving problems in agriculture and the environment"—is delivered by over 500 employees across more than 20 global sites 1 .

While CABI's work is vast, covering everything from invasive species to microbial services, its PlantwisePlus program perfectly illustrates its modern approach to agricultural science 1 . This global initiative aims to help 75 million smallholder farmers in low-income countries produce more and safer food by reducing crop losses 1 .
The experiment is not confined to a laboratory but is implemented across entire national agricultural systems. The methodology is built on three core impact pathways:
Supporting countries to predict, prevent, and prepare for plant health threats, especially in the face of a changing climate. This involves monitoring pest movements and developing early warning systems 1 .
Encouraging the adoption of more sustainable pest management practices to reduce reliance on harmful chemical pesticides 1 .
Establishing plant clinics, run by trained "plant doctors," where farmers can bring sick plants for diagnosis and management advice 1 . This is the most visible and direct interaction with the farming community.
The success of this large-scale "experiment" is measured in the health of crops and the stability of farmer livelihoods. For instance, CABI's work in Ghana to improve phytosanitary systems directly led to the resumption of vegetable exports worth $15 million a year after a European Union ban was lifted 3 . Furthermore, the use of plant clinics allowed for the early identification of the devastating Fall Armyworm in Ghana in 2017, enabling a rapid response to contain the threat 3 . The results demonstrate that empowering farmers with accessible, science-based knowledge creates a more resilient agricultural system from the ground up.
Relative impact distribution of PlantwisePlus program components
| Impact Pathway | Methodology | Measurable Outcome |
|---|---|---|
| Pest Preparedness | Early warning systems; climate change modelling; pest monitoring. | Early identification of Fall Armyworm in Ghana, allowing for containment 3 . |
| Pesticide Risk Reduction | Promoting integrated pest management (IPM); providing access to biocontrol information. | Increased use of biological control agents, reducing chemical residues in food and environment. |
| Farmer Advisory | Network of plant clinics and digital resources providing diagnostic and treatment advice. | Improved crop survival rates for millions of smallholders; restored $15M in vegetable exports from Ghana 3 . |
The work of CABI and modern agricultural researchers relies on a sophisticated toolkit that blends traditional knowledge with cutting-edge technology. This suite of resources enables everything from fundamental species identification to large-scale data analysis.
Using a pest's natural enemies (parasitoids, predators) for control instead of chemicals.
Providing scientists with a comprehensive, searchable record of global scientific literature.
Interactive, encyclopedic resources on pests and diseases, supporting rapid diagnosis and decision-making.
Using satellite data and mapping to monitor crop health, predict pest outbreaks, and assess environmental changes.
| Tool or Resource | Function in Research | Example from CABI's Work |
|---|---|---|
| Biological Control Agents | Using a pest's natural enemies (parasitoids, predators) for control instead of chemicals. | Successful control of the Winter Moth in North America with the parasitoid Cyzenis albicans 3 . |
| Global Databases (e.g., CAB Abstracts) | Providing scientists with a comprehensive, searchable record of global scientific literature. | CAB Direct platform holding over 10 million records, crucial for literature reviews and meta-analyses 3 . |
| Digital Compendia (e.g., Crop Protection Compendium) | Interactive, encyclopedic resources on pests and diseases, supporting rapid diagnosis and decision-making. | Used by extension workers and researchers worldwide to identify and manage new threats 3 . |
| Remote Sensing & GIS | Using satellite data and mapping to monitor crop health, predict pest outbreaks, and assess environmental changes. | The Pest Risk Information Service (PRISE) uses satellite data to warn farmers in sub-Saharan Africa of pest outbreaks 3 . |
| Statistical Design & Analysis | Ensuring field experiments are properly structured and data is correctly interpreted to yield valid results. | Early adoption of methods from Rothamsted Statisticians to account for high variability in perennial crop trials 2 . |
From its origins in classifying insect specimens to its current use of satellites for pest forecasting, the journey of the Commonwealth Agricultural Bureaux reflects the evolution of scientific practice itself.
CABI has demonstrated that the careful curation of knowledge, when combined with practical, on-the-ground action, can create a powerful force for global good. In an era defined by climate change and globalized trade, which accelerate the spread of pests and diseases, their mission has never been more critical.
The organization stands as a testament to the fact that long-term scientific investment and international cooperation are not merely academic exercises.
They are essential tools for building a world where every farmer, regardless of location or resources, has the knowledge to nurture their crops and feed their community.
The scientific endeavour that began over a century ago continues to grow, adapt, and defend the delicate balance of our global food system.
