I want to enhance a social and political geography of risks and the environment. Therefore, I will present a politicized and contextualized approach of risk issues I wish I could implement in next fieldworks. “Politicized”, because of the power relations and the socially rooted causes I want to highlight. “Contextualized”, because of the relations that must be assessed within socio-ecological systems (both social and biophysical), over time and across scales. Such encompassing framework stems from a personal research training process, still ongoing process, which is familiar to French-speaking, Latin-American and North-American literature on risks, and particularly on risks as social constructions. This framework allows addressing socially and politically oriented challenges related with a transformed environment, the “second nature”, a “humanized nature”, without ignoring the “first nature” and the necessity of biophysical laws.
