This is Hippolyte Affognon from the International Centre of Insect Physiology and Ecology (Head of Social Science and Impact Assessment Unit). A contribution to message 72 (from Matthieu Stigler, Dominique Barjolle and Sylvain Quiédeville): I think that social network analysis (SNA) can be very helpful to impact evaluation as social network is very important for knowledge dissemination. As we know, knowledge and information are elements that propel an increase in agricultural productivity and rural incomes. Impact is consecutive to adoption following knowledge and information dissemination. SNA can then be used as a method for identifying effective and relevant pathways for disseminating research results within a multisector system of organizations with the aim of strengthening adoption and impact. Also SNA can be used in capturing the spillover effects of technology adoption on impact.
