On Saturday, the New Museum will host IdeasCity festival, a free public event devoted to cities and culture, in Concrete Plant Park in the Bronx. This iteration of the festival, themed “New Ecologies 3755,” focuses on the effects of climate change in the borough. It will feature workshops, talks, performances, activities, food and even boat tours on the Bronx River, led by the organization Rocking the Boat.

IdeasCity was founded in 2011 and has organized gatherings all over the world. This one coincides with the United Nations Youth Climate Summit and a weekend of events leading up to the United Nations Secretary General’s Climate Action Summit on Monday .

V. Mitch McEwen, the curator for this year’s IdeasCity events, said she likes to think of this festival as a “happening.” “I’m borrowing that term from artist-led events in the mid-60s that combined art and activism,” she said. She said the wide umbrella of programming is tied together by climate change, and its connections to broader issues in society, culture, and the Bronx in particular.

The program includes music and storytelling performances, some organized in partnership with DreamYard, a local organization that works with youth, families, and schools; workshops on topics including land development and agriculture; and keynote conversations featuring Teddy Cruz and Fonna Forman — who have an architectural practice in San Diego that explores borders, infrastructure and public culture — and Jon Gray, of the Bronx-based culinary collective Ghetto Gastro.
