Mitigating climate change
through smart agriculture.

WSHG is a collaborative group of companies delivering climate-smart agricultural solutions to build resilience against climate change and rainfall variability in vulnerable communities.

What we do Join us today

/ Mission

We are a collaborative group of companies combating climate change. Our expertise bridges the gap between vulnerability and resilience in the agricultural sector.

For years, we have run on-farm trials at the foot of the Cherangany Hills to design systems that work for the people who actually grow food, mitigating the impacts of rainfall variability.

Every initiative we deploy from solar water pumping to vermicomposting is a calculated step towards climate-smart agriculture and long-term food security.

/ What we do

Five systems. One loop.

Each pillar is engineered to feed the next. Solar pumps water the crops; crop residues feed the digester; the digester feeds the worms; the worms feed the soil; the soil feeds us all.

Solar Water Pumping

Drip, sprinkler, and micro-spray systems powered entirely by the sun.

We engineer off-grid irrigation that turns dryland plots into year-round producers sized for the smallholder and the urban rooftop alike.

Vermicomposting Systems

Eisenia fetida earthworms convert organic waste into living soil amendment.

Modular bins, climate-tuned bedding, and a continuous-flow design that yields premium vermicast in 45 days from kitchen and farm waste.

Fertiliser Tree Species

Gliricidia sepium for nitrogen fixation, fodder, and living mulch.

Intercropped at 4×4m spacing, Gliricidia restores depleted soils, breaks the maize-monoculture cycle, and adds resilience against drought.

Biogas Plant Construction

Fixed-dome and tubular digesters from 4m³ to 50m³, built on site.

Clean cooking energy plus nutrient-dense slurry, the upstream feedstock for our vermicompost loop. We design, build, and commission.

Research & Nutrient Enhancement

Action research on soil biology, microbial inoculants, and crop response.

On-farm trials since 2018 in partnership with WSHG, documenting yield, nutrition, and economic outcomes for regenerative practice.

BBC Feature: Vermicomposting

Heard of vermi compost? Well its simply organic compost but using worms to help in the decomposing process. How do you do it and what are the benefits? We head to Kenya to meet two sisters Betty and Ruth who make vermi compost in their back garden and they tell us how it helps in climate change.

BBC What’s New and BBC Actu Jeunes are the BBC’s first bilingual programmes for teenagers, brought to you by the BBC World Service to discuss important issues for young people across Africa.

ACLP Webinar Series

This is the 1st of a series of webinars planned on the vermicomposting project in partnership with the African Climate Leadership Program, discussing technical fundamentals and community impacts.

The integrated cycle

Waste

Organic inputs from kitchen, farm, livestock.

Biogas

Anaerobic digestion → clean cooking energy.

Slurry

Nutrient-rich effluent leaves the digester.

Earthworms

Eisenia fetida process the slurry & bedding.

Vermicompost

Living soil amendment, microbially active.

Soil → Crop

Resilient yields. Cycle restarts.

/ Our story

A collective effort, a collaborative group, and a unified response to climate change.

Wesakhulila Self Help Group (WSHG) began with a clear mission: to confront the devastating impacts of climate change and rainfall variability on local agriculture in Western Kenya.

By combining our diverse skills and expertise, we set out to prove that smallholders can overcome these challenges through climate-smart agriculture. Today, our group of companies leads the region in deploying sustainable, replicable systems that build resilience.
