Abstract
BACKGROUND: Suicide in Sri Lanka is a major public health problem and in 1995 the country had one of the highest rates of suicide worldwide. Since then reductions in overall suicide rates have been largely attributed to efforts to regulate a range of pesticides. The evolution, context, events and implementation of the key policy decisions around regulation are examined.Entities:

Application of quality procedures to pesticide policymaking study
| Quality procedures | Concerns addressed | How procedures applied |
|---|---|---|
| Purposive selection | Bias | Use of local research team and snowball procedure to check ‘outliers’ |
| Grounded theory | Original theorizing | Development of emergent themes distinct from interview framework |
| Triangulation | Confirmation or refutation of internal validity | Use of interviews, review of documents, papers and stakeholder tables |
| Reflexivity | Validity of interpretations | Disclosure of researchers’ position for readers |
| Respondent validation | Confirmation or refutation of interpretations | Discussion of outcomes, iterative approach to interview framework, review of paper |

Characteristics of the phases of policymaking related to pesticide regulation in Sri Lanka 1960–2008
| Political and economic context | Knowledge and influence networks | External environment | Evidence and communication | |
|---|---|---|---|---|
| Pre-1980s | Import controls to protect foreign exchange 1976 economic liberalization package—proliferation of agro-chemicals | Government of Sri Lanka (GoSL) asks for assistance from FAO to draft Control of Pesticide Act DoA participating in international chemical safety agreements discussions | Rising concern about chemical safety Green revolution–synthetic | Local agronomy research into appropriate pesticides to rationalize use Links to international research |
| 1980s | Tabling and ratification of Control of Pesticides Act ORP established—strong technical facility free from external pressure Process of registering chemicals | NPIC established with assistance of WHO and International Development Research Centre (IDRC) Links between NPIC and ORP begin Strong links between ORP and International Program on Chemical Safety (IPCS) | International Code of Conduct for the Distribution and Control of Pesticides Establishment of multi-agency IPCS | Evidence of problem with self-poisoning starts to emerge in hospital settings Occupational health paper outlines the problem of suicide |
| 1990s | Sri Lanka cited by WHO as having one of highest rates of suicide in the world Presidential Committee of prevention of suicide set up Bans on some pesticides, predominantly resulting from chemical safety agenda | Local links between health and agriculture strengthened Informal and formal mechanisms develop | WHO quarterly statistics published and highlights high rate of suicide in Sri Lanka Interaction continues on IPCS-setting chemical safety agenda | Local evidence of problem strong Crossover from clinical medicine to risk factors, geographic, methods |
| 2000s | Delegated policymaking Technical responses supported | Epistemic community becomes powerful and pervasive Links with industry strengthen support for decision making | Little direct involvement; most external presence manifest through international researchers and their linkages | International research collaborations strengthen capacity for research Engagement between policymakers and researchers strong Industry collaborate with research |
