Impact Evaluation of Climate-Smart Agriculture for Farmers

Overview
The Kenya Climate Smart Agriculture Project was a World Bank-financed national programme designed to increase agricultural productivity and build resilience to climate change risks among smallholder farming and pastoral communities. ACAL was engaged to conduct the project's impact evaluation, assessing achievement against the key performance indicators in the results framework and the intermediate outcome indicators set out in the Project Appraisal Document.
Impact evaluation of a World Bank-financed national agriculture programme, conducted against the PAD results framework
Productivity and income effects for smallholder farmers assessed across project areas
Project performance evaluated against the international criteria of relevance, effectiveness, and efficiency
Lessons and experiences documented to guide the design of future agricultural development programmes


Client Context
Kenyan agriculture carries a structural contradiction: it employs the majority of the rural workforce and anchors the economy, yet it is dominated by smallholders exposed to increasingly erratic rainfall, drought cycles, and degraded natural resources. The Kenya Climate Smart Agriculture Project was among the government's most significant responses, a World Bank-financed operation promoting climate-smart practices, strengthened agricultural research and seed systems, and community-driven investments intended to raise productivity while building resilience to climate shocks.
Programmes of this scale end with an obligation as important as any disbursement: an honest account of what changed. The World Bank's results architecture requires it, the National Treasury's future borrowing decisions depend on it, and the design of successor programmes is only as good as the evidence inherited from the last one.
The Challenge
Evaluating a national agriculture programme is methodologically unforgiving. Productivity and income changes among smallholder farmers must be measured across dispersed rural populations, then attributed credibly to project interventions rather than to weather, prices, or parallel programmes operating in the same counties. The evaluation had to work from the project's own accountability documents, the key performance indicators in the results framework and the intermediate outcome indicators in the Project Appraisal Document, so that findings would map directly onto the commitments made to the financier.
The assessment also had to go beyond indicator arithmetic. The evaluation was required to judge the project against the established criteria of relevance, effectiveness, and efficiency, and to extract the lessons and experiences that would guide future agricultural development programming. That demanded field evidence gathered from farmers and implementing institutions, quantitative rigour in the analysis, and the evaluative judgment to explain not just what the numbers were but why.
Our Approach
ACAL structured the evaluation to meet World Bank evidentiary standards while capturing the ground-level reality of smallholder experience.
Evaluation framework anchored on the PAD: every key performance indicator and intermediate outcome indicator mapped to measurement instruments before fieldwork began
Mixed-method evidence collection: structured farmer-level surveys paired with institutional interviews and field verification across project areas
Attribution and performance analysis: productivity and income effects assessed for project beneficiaries, with performance judged systematically against relevance, effectiveness, and efficiency
Lessons synthesis for forward design: findings converted into documented lessons and recommendations aimed explicitly at future agricultural programmes
Solution Delivered
ACAL delivered the complete impact evaluation: methodology and instruments, national field data collection, analysis against the full results framework, and a final evaluation report assessing the project's achievements in raising smallholder productivity and incomes, together with its performance on relevance, effectiveness, and efficiency.
The report gave the project's stewards what closing a World Bank operation requires, an evidence-based account of achievement against commitments, and gave the sector what it needed next: documented lessons from one of the country's largest climate-smart agriculture investments, structured to inform the design of successor programmes.

Impact
The evaluation converted the project's implementation record into verified evidence: where climate-smart interventions raised productivity and incomes, where results fell short of design, and what separated the two. That evidence base serves every audience the programme answers to, from the financier closing its books to the ministries designing what follows.
For Kenya's agricultural policy community, the documented lessons carry value beyond the project itself. Climate-smart agriculture is central to the country's food security strategy and to the climate finance instruments now flowing toward the sector, and credible evaluation evidence of what works at national scale is the scarcest input in that conversation. The evaluation positions future programmes, government and donor alike, to build on measured experience rather than assumption.
Key Takeaways
A programme's evidence is part of its return on investment
The value of a national project includes the verified knowledge it leaves behind. Rigorous impact evaluation converts spending into evidence, and evidence into better-designed successor programmes. Skimping on evaluation writes off part of the investment.
Attribution discipline is what separates evaluation from reporting
Counting outputs is administration. Establishing what changed for farmers, and how much of that change the project caused, is evaluation. The credibility of every claimed result rests on that distinction.
Climate finance will flow to evidenced agriculture
As climate-tagged concessional finance expands, agricultural programmes that can demonstrate measured resilience and productivity outcomes will absorb a growing share of it. Evaluation capability is becoming a financing qualification for the sector, not an afterthought.
