spatial integration of youth constitutes a major challenge in africa where poor and lowincome youth are marginalized or excluded from employment opportunities and are often trapped within their neighbourhoods by virtue of ethnic class religious and other types of segregation for example the colloquial swahili adopted by tanzanian youth especially in dar es salaam should be drawn into the culture of the city rather than disparaged despite their critical role in african urban food security informal urban agriculturalists are mostly tolerated rather than supported in this respect the protection of valuable urban agricultural lands from encroachment is a linked challenge one which requires a response to the broader challenges of unplanned informal settlement growth
