Short Course Description:

This online course will introduce you to the threat posed by ground level ozone pollution to tropical agriculture. It will give you the knowledge, skills and confidence to identify when and where ozone is likely to pose a threat to tropical crops. You will gain the skills to identify ozone damage in a variety of tropical crop species, with comparisons to other threats (free). You will understand how and why ozone causes crop damage. Understanding the how and why allows formulation of practical management options, either through adaptation or mitigation. The training involves exercises with explicit focus on local contexts, allowing you to consider ozone as a current and future threat in your region. You will have the opportunity to demonstrate the knowledge and skills you have gained through answering multiple-choice quizzes. UKCEH have worked in partnership with CABI (Centre for Agriculture and Bioscience International; https://www.cabi.org/) to develop this course.

Why do this course?

Ensuring a stable food supply is critical for human wellbeing. When producing food, crops are exposed to numerous threats such as pests and diseases, heat stress and drought. All of these can reduce crop yield and be economically costly to manage. Ground level ozone pollution is another, often overlooked, costly threat to agricultural production.

In the coming years, this gas will increase in concentration with damaging effects on plants including reduced crop yield and quality. The increase in ozone concentrations is happening all over the planet.  Scientists expect the effects to concentrate in important tropical and sub-tropical crop-producing areas e.g. sub-Saharan Africa and parts of Asia.

It is important that crop scientists, plant breeders, agriculture and food security students and researchers, policy makers and farmers are aware of the hidden threat that is ozone pollution. This course raises that awareness. It also provides the foundations as to how to manage and adapt to the ozone threat in an era of multiple environmental challenges. 


Learning outcomes:

  • You will have a better understanding of how, where and when ozone poses a threat to tropical agriculture
  • You will gain skills in identifying visible symptoms of ozone damage on a variety of crop species
  • You will acquire knowledge on practical management techniques to mitigate or adapt to the threat of ozone pollution
  • You will have increased awareness of resources that are available to help understand and tackle ozone pollution e.g. ICP Vegetation smartphone App
  • You will understand ozone risk assessment methodologies
  • You will become aware of options for improved stakeholder engagement


You do not need any previous knowledge or skills in relation to ozone pollution in tropical agriculture.

Software and Hardware requirements

You will need a laptop, desktop or tablet and access to the internet. We recommend a minimum of 1MB download speed.

A second (external) screen will be an advantage, but is not essential.
