Biodigester: Simple, Systematic, Life-changing

Updated: Oct 1, 2025 Reading time: 1 minute

Meet Nsamba, a farmer from Zambia, and the face of community-led climate-resilience. In a world where of climate change impacts climate-vulnerable communities disproportionate, Nsamba's adoption of biogas underscores the systemic change we need.

Biodigestion, what started as a simple means of providing clean cooking fuel became so much more. Nsamba collects fresh cow dung daily to feed the biodigester that fuels his family's stove. In doing so, he protects the forests around his home, because what's left over from the biodigestion process—nutrient-rich bioslurry—has revolutionised his farming.

 

"I used to buy fertiliser every season and mealie meal every month," Nsamba shares. "Now I produce my own organic fertiliser and only buy mealie meal once a year."

His thriving vegetable garden in Mongu isn't just feeding his family—it's funding education for his children and supporting his extended family too. This is climate-smart agriculture in action: building food security while reducing environmental impact.

At PIN, we work in solidarity with communities like Nsamba's to fight climate injustice. We believe in locally-led climate action that addresses the root causes of vulnerability while building resilience against future shocks and we practice this in our work with the communities we support.

Though our Czech Development Agency-funded biogas project has ended, farmers like Nsamba continue to show us that when communities have the right tools and support, they become powerful agents of climate resilience.
