This contribution engages an analysis of the complementarity relationships in local waste management to the requirement of a coherent urban governance that is informed by the theoretical approach of the centre-periphery relationship. It is interested in the essence of the construction of the central and peripheral territories of household waste as a result of the processes and logics of central and peripheral actor figures. The choice of the study area was made in response to the objectives of analyzing the logics of spatialized actors and observing the practices of household waste circulation in these different spaces. We analyze two scales of entry: the Yaounde urban community and the district councils [of Yaounde 6 and 3] that make up the community, which are more marked by a strong pre-collection and collection of household waste by the private sector on the one hand, as well as Hysacam. Data collection was based on a variety of institutional and scientific documentary sources and on non-structured interviews with officials and non-officials. The Yaounde Urban Council (YUC), pre-collection operators, NGOs and waste collection companies-PAN and Hysacam constitute sites of investigation.

Purpose: This article intends to examine the improvement in fighting against food insecurity in Cameroon since February 2008, a period marked with so-called hunger riots. In response to this, and in order to reply satisfactorily to this social crisis and the security that predates it, the government set up, at the end of 2008, the national food security programme (NFSP). This programme, which is the site of our empirical investigation, has undergone some vicissitudes and a marked evolution up to now. Methodology: Based on Using participant observation, non-reactive data collection techniques and socio-historical analysis, the article highlights the concept of the food security policy process, which does not escape the enlightening analytical framework of the advocacy coalition framework. It proposes, based on the analysis of the interpenetration of the NFSP by state and others institutional actors, to outline the contours of a category of negotiated and incremental food security policy process. Findings: Therefore to improve the food security policy process, a social division of labour is needed between the decision-making centre – the Inter-ministerial Committee on Food Security (CISA) and the Steering Committee (COPIL) – and the technical expertise centre – the Technical Group on Food Security (GTSA). Unique contribution to theory, practice and policy: The NFSP should play a more synthesizing role between these two centres in terms of the framework for the elaboration of the national food security policy strategy.
