In December last year, Cambodian-American filmmaker Kalyanee Mam’s short film Lost World screened at our Shifting Landscapes exhibition in London. Kalyanee’s films tenderly document the changing cultural and ecological landscapes of her homeland, and in Lost World she shares the story of a community in Koh Sralau whose livelihoods are threatened as the mangrove forests they depend on are ruthlessly mined for sand to build an “eco-park” in Singapore. In this conversation, recorded live at the exhibition, Emergence executive editor Emmanuel Vaughan-Lee speaks with Kalyanee about her years-long process of creating the film, and the intimate relationships she holds with people and land that allow her to tell powerful, and often heartbreaking, stories of changing landscapes from a place of humility and connection.  Read the transcript  Watch Kalyanee’s short film Lost World and read her companion essay Learn more about your ad choices.
