**Abstract**

In recent times, the term "sustainability" has come to gain significant popularity in policy-oriented research and has become part of our everyday lexis in higher education research. Yet, in an attempt to deal with the issue of sustainability planning in research project proposals, the term has been conceptualized to refer solely to financial sustainability as if to say other types of sustainability either do not exist or do not matter. This chapter addresses this issue of sustainability planning in higher education research. In the process, financial sustainability is elucidated, and through that two other categories/types of sustainability are identified and discussed crisply for rumination. Following up on this, steps to sustainability planning are outlined to set in context the contention of the chapter that sustainability planning in research project management requires long term planning to facilitate diverse donor engagements and for improving institutional capacity of target populations. Thereafter, and using an example of a research proposal which responds to Open Call for project proposals for funding from a renowned multilateral funding agency, the chapter exemplifies how sustainability planning in research project proposals can be addressed to help strengthen the proposals to attract research funding from potential donors.
