Andrew Vayda and Bradley Walters (1999) criticize political ecologists for presupposing “the importance ... of certain kinds of political factors in the explanation of environmental changes” (167). Vayda and Walter's response to overly political approaches in political ecology is to encourage what they call “event ecology”,[3] focusing on human responses to environmental events without presupposing the impact of political processes on environmental events. The critique has not been taken up widely. One example of work that builds on event ecology, in order to add a more explicit focus on the role of power dynamics and the need for including local peoples' voices is Penna-Firme (2013) "Political and Event Ecology: critiques and opportunities for collaboration".[citation needed]
