The purpose of this study is to assess the influence of environmental scanning on performance of HIV and AIDS interventions managed by non- governmental organisations (NGOs) in Nyanza Region and the moderating influence of stakeholder participation in such relationship. The study adopted ex-post facto survey design in a mixed method approach.

Self-administered questionnaires and Key informant interview guides were used to collect data. It was established that there was a significant weak positive relationship between environmental scanning and the performance of HIV and AIDS interventions, r (50)=0.117,p= 0.418,CL=95%. Stakeholder participation significantly moderated the relationship between environmental scanning and performance of HIV and AIDS interventions, r (50)=0.024,p=0.033,CL=95%. It is inferred that most organization conducted environmental scanning but did not realize optimal outcomes. Environmental scanning and stakeholder participation added value to HIV and AIDS interventions, though to a
