Our work aims to identify lethal pesticides responsible for suicides and end their use through regulatory action – banning and phasing them out. We work in low and middle-income countries (LMICs) with national pesticide regulators, public health researchers and civil society.

We work in countries where pesticide suicide is a recognised problem

We conduct research to identify the pesticides responsible for deaths

We support the work of national pesticide regulators

We support regulatory action to ban or phase out lethal pesticides

We measure the impact of pesticide bans on suicide rates and agriculture

We also support regional action on highly toxic pesticides. We have developed collaborations with five regional pesticide regulatory bodies in in the Caribbean, West Africa, East Africa, and Southern Africa.
Our close collaboration with CABI and WHO Pakistan has led to the establishment of a national forum for pesticide risk reduction. A number of pesticides have already been identified for banning and we are supporting transitions to safer alternatives and monitoring of poisonings.
We supported the establishment of a national poison centre and a national forum that includes toxicologists, pesticide regulators and agricultural researchers and advisors to support moves away from highly hazardous pesticides with a focus on those used most frequently in self-harm.
India has one of the highest rates of pesticide suicide in the world and is a priority country for CPSP work.
Our India-based team are working closely with policymakers and research institutes at both central and state level to support pesticide regulation, collect data on pesticide poisoning cases, and measure impact from existing bans.
CPSP has been working in Nepal since 2017. Our initial work aimed to identify the pesticides responsible for the majority of pesticide suicides in Nepal. In 2019, Nepal banned eight pesticides, including two identified by our study. A further two pesticides were banned in 2024.
We are now undertaking data collection to monitor the impact of the bans on health and agriculture. We are also continuing to monitor which pesticides are causing serious poisonings and deaths in Nepal, working in partnership with the Centre for Mental Health and Counselling - Nepal (CMC Nepal).
We work with researchers at Rajarata University and South Asian Clinical Research (SACR) to identify the pesticides that are causing most deaths in the country and support the government in effective regulation.
We also work in affiliation with the NIHR RIGHT4 project on acute poisoning, to identify the pesticides that cause most harm to pesticide sprayers. Both these sets of data were used to support the listing of carbosulfan in the Rotterdam Convention’s Annex 3 in 2025.
