PETRRA was a research funding project, funded by DFID, and managed by IRRI Bangladesh. Research grants were given to individual organisations, and partnerships of organisations, through a competitive grant making mechanism. The aim of the project was to contribute to the alleviation of poverty in Bangladesh through research which enabled increases in the rice productivity of "resource poor rice farmers".  The network diagram below shows the full set of contractual relationships between the project management unit (shown as PETRRA, the grey circle) and the organisations participating in the 44 different research projects funded by PETRRA.

Participating organisations are color coded by type: Green = government bodies, Red = NGOs, Yellow = Universities, Blue = international research institutions, Brown = private sector organisations. Some of the relationships shown in the network diagram pre-existed the project, most notably the relationship between PETRRA (i.e. IRRI Bangladesh) and BRRI (Bangladesh Rice Research Institute). Many other relationships were new, most notably the linkages between BRRI (a government body) and the various NGOs. Also new was the relationship between some of the universities and the NGOs. While the original project design had no explicit objectives relating to the establishment and/or expansion of different kinds of institutional relationships, in practice as the project developed it became clear that the continuation of the Government-NGO and Universities-NGO relationships was important, and should be encouraged.
