What is Diaspora Missiology?

From the Lausanne Conversation titled Diaspora Missiology:

"Diaspora Missiology" has emerged as a biblical and strategic field of missiology and is defined by the Lausanne Diaspora Educators Consultation (Read about this consultation at http://www.lausanne.org/diaspora-2009/consultation-on-diaspora-missions.html) as: a missiological framework for understanding and participating in God’s redemptive mission among people living outside their place of origin. 

Diaspora Missiology necessitates interdisciplinary study of academic fields related to who, what, when, where, and how populations are moving (e.g. anthropology, demography, economics, geography, history, law, political science, and sociology) and classic missiological study (e.g. theology, missiology, biblical studies, evangelism).
