This thesis looks at defiance in civil society and aims to contribute towards a deeper understanding of contestation against regimes that restrict the expansion of the political playing field in sub-Saharan Africa. It also analyses the role of contemporary African activists in these contestations, and examines why some social contestation process are successful and others not. The role of Mozambican activists from aid-supported NGOs in relevant political movements between 2010 and 2015 is a key issue. The first part of the thesis offers a theoretical overview of civil society as contesting actor in Africa and Mozambique, and outlines the construction of concepts of civil society latency, defiance and co-construction through a theoretical framework that draws on the literature on moral economy, social movements, contentious politics, the public sphere, power and competitive authoritarianism. Analysis of two contrasting civil society organisations, the LDH (the League for Human Rights) and UNAC (the Mozambican Peasants' Union), aims to give a better understanding of public spaces for participation and defiance, and to follow the movement of activists from urban areas towards traditional indigenous sectors so as to ensure that vital issues for communities are brought into the public sphere. It also looks at the neutralisation processes suffered by organisations that offer support and/or directly organise contestation of government initiatives and policies that have a negative impact on the population. The case studies draw on research over a period of three years in the city of Maputo and the provinces of Nampula, Cabo Delgado, Tete, Zambezia and Manica. They examine the reasons for contestations around land issues between 2010-2015, focusing on peasants' and NGOs' resistance to the ProSAVANA agrarian development project, and on urban protests against abductions and against the 2012-2015 return to civil war, investigating the role of European donors and government in the near destruction of one of the most well-known NGOs in Africa.

Civil society organisations (CSOs) in the UK are currently engaged in attempts to make food systems more sustainable, i.e. greener, fairer and healthier. These efforts have been maintained over several decades, for instance the Soil Association was launched in response to concerns about modern agriculture and food in 1946. But more sustainable food systems remain marginal. Thus, the aim of this thesis is to improve understanding of the important roles that CSOs can and do play within processes of large-scale social change (or ‘transitions'). It does this by developing a typology of the distinguishable roles played by CSOs in transition, and relating this to empirical findings from three UK case studies. Through a mixture of field observations, documentary analysis and in-depth interviewing, it makes a number of relevant findings. First, it provides detailed empirical characterisation of the activities, relationships with other actors, and stated intentions of specific CSOs. Second, it finds that CSOs chart unique transformative pathways, both individually and collectively, which emerge from their interactions and strategic repositioning over time. Third, rather than being guided by a single shared vision of transition, CSOs are found to be engaged in a plurality of intended transformations that contend with, cross-cut and partially encompass each other. These findings contribute to scholarly knowledge about how civil society innovation operates at different structural levels, targets different elements within socio-technical systems, and engages different kinds of actors and practices. They also reinforce and extend existing understandings of how civil society actors exercise power in the context of transitions, and reveal how systemic perspectives – such as underlie transitions theory – can obfuscate both the intentions and activities of the actors involved, thereby raising questions about the attribution of agency in studies of transition.
