Towns and cities in this group have an average city size of 20 000 inhabitants. Despite their small size, rural clusters have a relatively high market potential – total population living in the region of the agglomeration - implying that they are located in areas with high rural densities, for example within the main agricultural production areas of Benin, Côte d’Ivoire and Ghana. Their average local dominance (the measure of the size of an agglomeration relative to the size of other agglomerations in the region) is low. Combined with high market potential and small city size, this highlights the particular tendency of these agglomerations to cluster together. The large number of agglomerations in this group can be linked to the process of in situ urbanisation, or the transformation of rural settlements into urban or quasi-urban settlements. This is a key characteristic of the urbanisation dynamic and the emergence of new agglomerations in West Africa. Of the 566 new urban agglomerations that ‘emerged’ in the ten years between 2000 and 2010, two-thirds (375) are rural clusters. These new towns are a key feature of urban-rural linkages, driving territorial transformation processes and acting as entry points to the food system for the vast majority of the region’s family farms.

Eight million pEoplE in northErn nigEria facing acutE food insEcurity
T he October 2016 analysis of the Cadre harmonisé1 expands its
coverage to include for the first time 16 out of 36 states, almost half of Nigeria. In these states, some eight million people are currently facing acute food insecurity (phases 3-5, October-December 2016). Due to the Boko Haram insurgency and massive population displacement, the three northeastern states, Adamawa, Borno and Yobe, have

reached extremely high levels of food insecurity (Maps & Facts no 44). While humanitarian access is improving, the situation remains particularly worrisome in the state of Borno, where nearly 60% of the population (3.3 million people) are still facing acute food insecurity (phases 3-5), including 55 000 people threatened by famine (phase 5). If no appro-priate measures are being taken, the current food and nutrition situation
is likely to get worse during the next lean season in June-August 2017. By then, the Cadre harmonisé projec-tions indicate that the number of severely food insecure people in the 16 analysed states could reach 8 to 10 million people. Analytical tools, data collection methods and training for local administrations need to be further developed in order to fine-tune and expand the analysis of the Cadre harmonisé to all parts of Nigeria.

URBAN-RURAL LINKAGES AND THE EMERGENCE OF NEW URBAN AGGLOMERATIONS
Half of the 1 939 urban agglomerations in West Africa are considered
to be rural clusters. Towns and cities in this group have an average city size of 20 000 inhabitants. Despite their small size, rural clusters have a relatively high market potential – total population living in the region of the agglomeration - implying that they are located in areas with high rural densities, for example within the main agricultural production areas of Benin, Côte d’Ivoire and Ghana. Their average local dominance (the measure of the size of an agglomeration relative to the size of other agglomerations in the region) is low. Combined with high market potential and small city size, this highlights the particular tendency of these agglomerations to
cluster together. The large number of agglomerations in this group can be linked to the process of in situ urbanisation, or the transformation of rural settlements into urban or quasi-urban settlements. This is a key characteristic of the urbanisation dynamic and the emergence of new agglomerations in West Africa. Of the 566 new urban agglomerations that ‘emerged’ in the ten years between 2000 and 2010, two-thirds (375) are rural clusters. These new towns are a key feature of urban-rural linkages, driving territorial transformation processes and acting as entry points to the food system for the vast majority of the region’s family farms.

LIENS URBAINS-RURAUX ET ÉMERGENCE DE NOUVELLES AGGLOMÉRATIONS URBAINES
La moitié des 1 939 agglomérations urbaines en Afrique de l‘Ouest
sont considérées comme des grappes rurales. Les villes de ce groupe ont une taille moyenne de 20 000 habitants. Malgré leur petite taille, les grappes rurales ont un potentiel de marché relativement élevé - la population totale vivant dans la région de l‘agglomération - impliquant qu‘elles se situent dans des zones à forte densité rurale, par exemple dans les principales zones de production agricole du Bénin, de la Côte d‘Ivoire et du Ghana. Leur niveau de dominance locale (la mesure de la taille d‘une agglomération par rapport à la taille d‘autres agglomérations dans la région) est en moyenne faible, ce qui, combiné à leur potentiel de marché élevé et à leur petite taille,
explique la tendance particulière de ces agglomérations à se regrouper. Le grand nombre d‘agglomérations de ce groupe est lié au processus d‘urbanisation in situ, c’est-à-dire à la transformation d’un habitat rural en habitat urbain ou quasi urbain, une caractéristique clé de la dynamique d‘urbanisation et l‘émergence de nouvelles agglomérations en Afrique de l‘Ouest. Sur les 566 nouvelles agglomérations urbaines qui ont «émergé» entre 2000 et 2010, les deux tiers (375) sont des grappes rurales. Ces nouvelles villes jouent un rôle clé dans les liens urbains-ruraux, contribuant au processus de transformation territoriale et offrant des points d’entrée dans l’économie alimentaire pour la grande majorité des exploitations familiales.
