Sustainability component in grant writing

I did a proposal and secured funding. In this project, I proposed the development of a postgraduate program, which I succeeded did. It's currently undergoing the university approval process. Once the Senate approves it, then we will begin to admit students. Our proposed sustainability was continuous capacity building.

However, I have also failed to secure funding even when I indicated sustainability such workshops, publications etc. I am not sure what the problem could be. Your feedback will be highly appreciated 

The sustainability issue has been a key impediment for me too in many grant propasals. 

In my proposal on HIV-NCD coomorbidity, i recommended that the management of the two conditions be integrated across the country and implemented together.

From my experience, the most convincing sustainability plans are the ones that clearly show who continues what, with what resources, and under what system once the funding ends. Funders are generally not persuaded by broad statements about “long-term impact” unless there is a concrete mechanism behind them. For example, instead of saying a health data project will “continue improving disease surveillance,” it is much stronger to show that the reporting tool has been integrated into a Ministry of Health’s routine data system, with trained county officers already responsible for maintaining it and a small budget line included in the ministry’s annual allocation. That shifts sustainability from intention to institutional ownership.

Another effective approach is demonstrating diversified continuation pathways. For instance, in a digital education project, sustainability might be shown through a mix of government adoption (schools integrating the platform into their curriculum), local capacity building (teachers trained as certified trainers who continue onboarding others), and partial cost recovery (institutions paying a small subscription fee for premium analytics dashboards). When funders see multiple reinforcing pathways instead of a single dependency, they are more confident the project will survive funding cycles.

Evidence also matters more than theory. I have found that letters of commitment from implementing partners carry significant weight, especially when they specify post-project responsibilities rather than generic support. For example, a county government stating that it will host the data platform on its servers and assign an IT officer for maintenance is far more convincing than a general “we support this initiative” letter. Similarly, showing early adoption helps—such as pilot sites that have already continued using a tool for several months after initial support ended.

Finally, realistic transition planning is critical. One strong example is budgeting for a “handover phase,” where funding gradually decreases while local institutions progressively take over costs. For instance, instead of abruptly ending donor support for a community health program, the final year might reduce external funding by 50% while increasing government or NGO co-financing to fill the gap. This staged transition shows funders that sustainability is not assumed but actively engineered into the project lifecycle.

At Purpose Rwanda, sustainability is not a section we fill to satisfy funders — it is built into how we work.

Our monitoring data shows that economically active recovered individuals maintain an 82% sustained recovery rate versus 60% for those without economic support. That gap is our sustainability argument. When recovery is linked to livelihood, the outcome sustains itself.

Specific approaches we have found effective:

1. Cooperative formation as the sustainability engine Rather than individual grants alone, we establish PATs (Purposeful Agents of Transformation) cooperatives with group savings mechanisms — so the model continues supporting new members long after the funding ends.

2. Community acceptance as infrastructure We invest in sensitising communities to receive reintegrated individuals. A community that welcomes a recovered person is a sustainability structure no budget line can replace.

3. Government integration Our NRS (National Rehabilitation Service) partnership anchors project approaches into national rehabilitation policy — giving outcomes institutional life beyond our organisation.

4. Honest data, not optimism We cite our own monitoring evidence. Funders respond to organisations that measure and report reality — including what still needs work.

We have not yet received a positive grant response. But we continue submitting because we believe God is positioning Purpose Rwanda at a time of His choosing.

Odoyo Cornellius's distinction between
"intention" and "institutional ownership" is exactly the
language I wish I would had when we first started writing sustainability
sections. It names precisely what separates a sustainability paragraph that
reads well from one that actually persuades a reviewer.

Since my earlier reply, we have refined our own
thinking further, and Cornellius's point about diversified continuation
pathways pushed me to be more explicit about ours. At Purpose Rwanda, our
sustainability now rests on three reinforcing legs rather than one:

Economic continuation: the 82%
vs. 60% recovery gap I mentioned earlier isn't just an outcome statistic, it's
become our strongest sustainability argument, because it shows funders that
livelihood support isn't a "nice addition" to recovery, it's the
mechanism that makes recovery self-sustaining after our direct support ends.

Institutional continuation:
following exactly the logic Cornellius describes with government data systems,
our NRS partnership means PAT-trained approaches are increasingly referenced
within national rehabilitation policy discussions, not dependent solely on
Purpose Rwanda's continued presence to survive.

Social continuation: this is the
one funders ask about least, and I think undervalue most. A community
sensitized to receive a recovered person back with dignity is infrastructure,
it doesn't appear on a budget line, but without it, every other sustainability
mechanism eventually fails. I'd be curious whether others here have found
effective ways to evidence this kind of social sustainability to
funders, since it's inherently harder to quantify than a government MOU or a
cost-recovery model.

I also want to acknowledge Silungile's note
above, mentorship and sustainable research design go hand in hand, and this
thread itself is a good example: some of the most useful sustainability
guidance I've received has come from exactly this kind of peer exchange, not
formal training.

So here's what I would genuinely like to learn
from this community: for those of you whose sustainability plans rely partly on
community acceptance, trust, or social buy-in rather than institutions or
budgets, how have you made that case convincingly to a funder who's scoring
against a rubric? I suspect this is one of the harder sustainability arguments
to write well, and I would value hearing how others have approached it.

One approach I have found effective is to move sustainability from the final section of the proposal into the project design itself. Funders are more likely to believe a sustainability plan when it is linked to existing institutions, systems, skills and resources rather than depending on continued external funding. For example, building local capacity, training staff who will remain within the institution, integrating activities into existing programmes, developing partnerships, and ensuring that project outputs can be adopted within existing structures all provide a stronger sustainability argument.
