Welcome to the Research Program on

Marginality. Addressing the Nexus of Poverty, Exclusion and Ecology

The research program on marginality comprises two research projects: MARGIP and TIGA.

The purpose of MARGIP is to analyze the nature and drivers of marginality and reveal the hidden potentials of the marginalized poor in order to match them with suitable investment and development opportunities.

After the preparatory phase from 2010-2012 the TIGA project now assesses cropping technology innovations for their potential to increase productivity and close yield gaps and thereby improve the lives of the rural poor.


MARGIP focuses on Bangladesh and Ethiopia. The TIGA project extends this focus and comprises also India (Odisha, Bihar) and Ghana.
