PESTROP - Pesticide use in tropical settings


PESTROP is an inter- and transdisciplinary research project, studying environmental, health and institutional dimensions of pesticide use in tropical settings. The overarching research questions addressed in the two study areas (Costa Rica and Uganda) are: What are the mismatches between institutional determinants of pesticide use and actual practice of pesticide applications on small-scale farms? Which changes in pesticide use practice and policy are needed to efficiently reduce human and environmental exposure to pesticides?
From a political science perspective, we examine the decision-making process and the implementation of public policies for a safer and more sustainable use of pesticides. With the help of a network analysis, we examine preferences for innovative policy instruments at the national level, the exchange of information (political and technical information) between the national and local levels, as well as the role of forums and cooperation. We interview national stakeholders and local street-level bureaucrats to identify the policy network.

In addition, we work with social psychologists to better understand the behaviour of individual small farmers and to derive effective political interventions from the psychological evidence.
