Morocco is facing important environmental damages due to climate change such as erosion, desertification and biodiversity loss. In addition, women are crucial actors in the combat against climate change consequences, partly thanks to their central role in agriculture and seed-saving. That is why Terre & Humanisme Maroc launched a project in 2013 providing training for rural women in order to emancipate them economically, while ensuring the preservation of the environment and biodiversity through the practice of peasant seeds production and conservation. In parallel, property rights on seeds and the Green Morocco Plan are privatizing and commercializing genetically engineered seeds in order to control food production. These policies are using concepts such as food security or sustainable development to justify the neoliberal expansion. However, the way they represent food security issues is largely differing from the way local women seed-producers understand and define them. Therefore, in the light of Bacchi’s What’s the problem approach and Feminist Political Ecology theoretical approaches, it is argued that there is a ‘scale mismatch’ between the ‘green’ Moroccan governance representations of food security and the local, and women seed-producers’ understandings and aspirations for sustainable livelihoods. Moreover, the thesis aims at highlighting relevant linkages between farmers’ rights and agricultural biodiversity. The analysis is built upon a discourse analysis of policies’ problem representations of food security and their politics of scale, followed by a comparison between these representations and the way women seed-producers think ‘otherwise’. Besides, a field based analysis of women seed-producers’ narratives was conducted through semi-directed interviews and participant observation during an internship with Terre & Humanisme Maroc in May and June 2017.
