Highly hazardous pesticides: a global health concern

Highly hazardous pesticides are a major public health concern. What measures are required to reduce the risks posed to human health and the environment? What are the responsibilities of pesticide manufacturers? And what responsibility does Switzerland bear, since it hosts the global market leader? We will discuss these questions on 18 June, with various high-level international panellists.

Approximately three million tonnes of pesticides are applied worldwide every year, an amount that has been constantly increasing since the 1990s, especially in low- and middle-income countries (LMICs), which account today for over half of pesticide use.

While farmers and rural residents are exposed most directly, residues of pesticides are found everywhere: in our food, our drinking water, in the rain and in the air. Warnings about the negative impacts of pesticides on human health and the environment are escalating.

The most dangerous pesticides, known as “highly hazardous pesticides” (HHPs), are used heavily in LMICs, despite being – for the most part – no longer authorised in Switzerland and the EU. According to estimates of Public Eye, in 2017 pesticides classified as such by the Pesticide Action Network generated 22 billion USD in revenue globally. Switzerland-based Syngenta plays a central role in this controversial business.

This very lucrative business is also very hazardous. In India, thousands of farmers are poisoned every year. In Brazil, the world’s largest consumer, millions are exposed to a cocktail of pesticides in the drinking water. Scientific studies conducted in this agricultural superpower show disturbing rates of congenital deformities, cancer and other chronic diseases in the regions with the highest levels of pesticide use.

In order to reduce risks to human health and the environment, UN agencies and experts call for urgent action to phase out the most hazardous pesticides and replace them with safer alternatives. We talk to various high-level panellists about the responsibility of states such as Switzerland as well pesticide manufacturers, to address one of the major concerns of our times.
