Almost three decades ago, when I started my doctoral studies, political ecology was emerging as a radical and exciting interdisciplinary field of research. One of the books that I found most compelling, and which later proved to be foundational for defining this field, was Land Degradation and Society. The authors, Piers Blaikie and Harold Brookfield, argued that it was necessary to develop a ‘regional political ecology’ approach because, “it is necessary to take account of environmental variability and the spatial variations in resilience and sensitivity of the land, as different demands are put on the land through time. The word ‘regional’ also implies the incorporation of environmental considerations into theories of regional growth and decline.” (1987: 17).

Now, Political Ecology is a well-established field, with numerous texts, journals, research groups and sub-fields of inquiry. There are many arguments about precise definitions of political ecology: whether it has enough ecology or enough politics or whether the methods are sufficiently rigorous or interdisciplinary. In short, there are plenty of people who have found it interesting enough to jump in and keep it alive through empirical research and theoretical debates. Whatever the trending debates, as a person interested in ‘regions’, my definition of political ecology stays close to Blaikie and Brookfield’s concept. I see political ecology as an approach that reveals the biogeographical outcomes of social relations within particular institutional landscapes over time. Simply put, political ecology reveals how past and present social actions and decisions make their mark on the landscape and influence subsequent actions and decision that societies undertake.

Here are some of my papers that engage with these issues.
