HIV/AIDS - To find articles focusing on some of the factors that have
made the problem of HIV/AIDS particularly bad for Southern Africa

Google - Aids dry sex

Google - hot, tight and dry

go to the WHO website or the FAO website

Google will bring up a large number of quality popular articles which
are useful. Some will have bibliographies. Check the bibliographies
and scroll down through what Google brings up in order to find
peer-reviewed scientific articles in reputable journals.

I spent maybe 5 minutes doing the above to help a student find
sources for her research paper on Agriculture, Food Supply and
HIV/AIDS in Southern Africa. A quick look identified some of the
following as either good articles (both peer-reviewed and/or popular)
or good leads to peer-reviewed articles or to quality sources such as
WHO (World Health Organization).
