AAC created a coordinated process that converted ecosystem diagnosis into two implemented tests and generated early evidence of farmer learning, adoption readiness and consumer-market interest.

— AAC Year One Impact and Learning Report

How change happens

The AAC impact pathway

Circular agriculture in Kenya is constrained not only by technical knowledge — but by evidence, extension capacity, trust, coordination, markets and finance.

Convene and diagnosePrioritise leverage pointsCo-design pilotsTest and measureAdapt and scale

Evidence gap

Limited locally validated agronomic and economic proof.

Extension-capacity gap

Insufficient practical exposure, tools and incentives for extension actors.

Trust gap

Limited confidence in advice, product claims and verification.

Coordination gap

Fragmented organisations and producers unable to build shared infrastructure.

Market gap

Weak visibility, availability, storytelling and demand-conversion mechanisms.

Finance gap

Limited products suited to transition timelines and early-stage risk.

Two proof-of-concept pilots

Pilot A & Pilot B

Capacity building through the extension system for 150 farmers — connected to consumer demand testing through market activation.

Building Capacity Through the Extension System

Pilot A tested whether practical, farm-based learning — delivered through Kenya's existing public extension system — could build farmer capacity in regenerative and circular agriculture at pace. The training cohort was 150 farmers in Kiambu County.

The Live-in Lab sat at Sylvia's Basket / Kilimo Endelevu Farm in Ndeiya. Five extension workers from Limuru, Kabete and Kikuyu took part, with support from the Kiambu County Director of Agriculture. Officers then carried a shared curriculum into farmer training across those three sub-counties. Baseline and endline surveys captured learning among 145 and 144 records respectively; 99.3% of surveyed farmers attended all or part of the training.

How it worked

  • Extension officers first learned on a working circular farm, not only in a classroom.
  • Delivery ran through the county extension pathway so knowledge could travel after the pilot.
  • 150 farmers were trained on the same regenerative and circular curriculum.
  • Learning was measured with baseline and endline surveys, including planned farm changes.
  • 150 farmers trained · 145 baseline records · 144 endline records
  • Average understanding score: 3.32 / 4 (83.1%)
  • Average confidence score: 3.54 / 5 (70.8%)
  • Top planned practices: mulching (88.9%), composting (84.7%), farm-waste reuse (81.2%)

Training and co-creation at Sylvia's Basket / Kilimo Endelevu Farm in Ndeiya — workshops, the regenerative curriculum, and the seed bank that keeps farm loops in motion.

Closing the Loop at Forest Food

Farm Showcase · 4 July 2026

A field day at Forest Foods — mulching, plant health, and planting together — so extension officers, partners and visitors could see regenerative practice on a working farm.

Pilot A curriculum

A Simple Farmer's Guide — Understanding Regenerative and Circular Farming

Based on the AAC Pilot A training curriculum at Sylvia's Basket Farm, Ndeiya, Kiambu. Written for farmers and walked through by extension officers.

  1. Chapter 1

    What is regenerative and circular farming?

    Circular farming brings waste, cost and risk back into use on the farm. Regenerative farming leaves land healthier each year. Together they mean less waste, a stronger farm, more income, and more nutritious food.

  2. Chapter 2

    Five principles

    A practical spine for the field — not a rigid package.

    • · Disturb the soil as little as possible
    • · Keep the soil covered
    • · Keep living roots in the soil
    • · Grow many kinds of plants
    • · Bring animals back onto the land
  3. Chapter 3

    Soil as the foundation

    Soil is alive. Farmers learn four field questions — can water get in, can air get in, can roots grow deep, and are living things present — and the practice of feeding the soil, not just the plant.

  4. Chapter 4

    Farm loops

    What already exists on the farm can cycle back into production.

    • · Nutrient loop — manure and compost
    • · Water loop — hold moisture, cut waste
    • · Seed loop — save from the healthiest plants
    • · Biodiversity and pest loop — mix crops, observe before spraying
    • · Livestock loop — housing, feed, and safe manure handling
    • · Energy and biomass loop — mulch and compost, not burning
    • · Home-made inputs — compost teas and sprays as a complement, not a substitute
  5. Chapter 5

    Why this matters — and first steps

    Lower input costs, less water work, less risk, stronger land over time, safer food, and trust with buyers. Farmers do not need to change everything at once: start with soil, one compost heap, cover bare ground, save seed, and fix one water loss.

Evidence from the field

What farmers learned — and plan to apply

Results from the 150-farmer Pilot A cohort in Kiambu. Understanding was strongest on production topics; market access and post-harvest remain areas for Year Two. Baseline challenges use 145 survey records.

  6. 6

    Jun–Jul 2026

    Implementation & evidence

    150 farmers trained across Kikuyu, Kabete and Limuru; consumer activation generated the first outcome datasets.

Most meaningful changes

What Year One achieved

From consultation to joint experimentation

A 38-member Working Group moved from individual perspectives to collective problem-solving — diagnosing, prioritising, designing and implementing two pilots together.

38-member Working Group · 2 workstreams · 2 pilot interventions implemented

County extension pathway to farmer learning

Pilot A combined county-linked extension participation with practical learning and an onward cohort of 150 farmers across Kikuyu, Kabete and Limuru.

150 farmers trained · 145 baseline and 144 endline records · 99.3% attendance

From general interest to explicit application plans

141 of 142 valid respondents were willing to apply a new technique; 131 of 144 recorded a specific farm change — evidence of adoption readiness.

91.0% with a specific action plan · 92.9% intending to start within one month

Market access as a collective trust problem

Pilot B reframed limited regenerative-product demand as requiring collective visibility, credible trust signals and coordinated storytelling.

Collective producer activation · consumer feedback · emerging trust identity

It's a simple shift with a big impact — beginning with minimal soil disturbance and building from there.

Knowledge that travels

The hardest part isn't the soil — it's the capital. Regenerative systems need financial instruments that recognise the time required for soil, tree and market systems to mature.
