In Africa, specifically, migrant social networks can help to build social capital to increase the social resilience in the communities of origin and trigger innovations across regions by the transfer of knowledge, technology, remittances and other resources . These could increase the flexibility, diversity and creativity of communities in addressing climate stress and open new pathways for co-development connecting the home and host communities.

In Africa, in particular, in terms of adaptation strategies Mozambique and Zimbabwe are clear examples of this because they have implemented relocation policies that have reduced the exposure of populations and migrants to disaster. In any case, it is important to build resilience in the long run. And for that, tools must be put in place that limit forced displacement after a disaster; promote employment programs, even if only temporary, for IDPs or establish funding plans to ensure their security; to minimize the vulnerability of populations from risk areas. This can limit the displacement caused by environmental shocks and better channel the positive spillovers (money transfers, experiences, etc.) from the migration to the origin countries/communities.

The figure of the "failed migrant", in most African countries, shows extreme heterogeneity. The causes associated with failure are most often from social and personal natures – feelings of personal failure for example– but can also be related to social isolation in the host countries. Although there has been some progress in the discussion [Ref: ''Cassarino J.-P. 2004. “Theorising return migration: the conceptual approach to return migrants revisited,” International Journal on Multicultural Societies, 6(2): 243–279''.] of the causes of the pathos of failed migration, there are still many unresolved issues. Factors such as a low social level, a change of life plan, unemployment, or even environmental stress (drought, high temperature, water scarcity, etc.) are often associated with an increased risk of failure when we know that most African migrants live in difficult socio-economic and ecological conditions.
