“…Kingdon's (1995) thesis on policy change, known as the Multiple Streams Framework, offers a heuristic for understanding how and why environmental policies gain or lose political support in fields such as climate change (Keskitalo et al 2013;Pralle 2009), flood risk (Johnson et al 2005;Penning-Rowsell et al 2006), and food production (Ackrill & Kay 2011).
