In February 2016, in conjunction with Museum Siam, Bangkok, Narisa initiated and directed BangkokEdge, Bangkok’s first Ideas festival. The two-day, free festival was attended by 25,000 people. The second BangkokEdge was held in January 2018 and was also very successful. The third is imminent and will take place between 1-2 February. The festival (and its pop-up MiniEdges) has included international authors such as Jung Chang, Hyensoe Lee, Sudha Shah, Thant Mying-U, Emma Larkin, Christina Lamb, Victor Mallet, Peter Frankopan, Anna Fifield and Lawrence Osborne, as well as many Thai authors such as architect Duangrit Bunnag, historian Charnvit Kasetsiri and novelist Veeraporn Nithiprapha, to name but a few.

It has included topics such as urbanism, heritage conservation, climate change and the environment, popular culture, LGBTi, women’s rights, memoirs, history, geopolitics, graphic novels and poetry. In addition, the festival screens films and organises workshops on topics from creative writing, illustration, repurposing old clothes, Thai crafts and cookery. The festival also provides a platform for local NGOs and has craft shops and delicious food.
