The Journal publishes analyses of social 
development issues as they affect the 
poor and marginalized. It deals especially 
with concerns relevant to sub Saharan 
Africa and is addressed to development 
and social workers, planners, policymakers 
and academics in a variety of 
fields. 
Published twice annually, the Journal 
seeks to enhance understanding of the 
social development processes so as to 
contribute to the planning and implementation 
of appropriate intervention 
strategies at different levels. Its goal is 
to discover how to target projects that 
are relevant to those most in need and 
how to maximize popular participation 
to create egalitarian and productive 
communities.
