Defra Monitoring, Evaluation and Learning (MEL) Facility

Defra and its family of arm’s-length bodies—including Natural England, the Environment Agency, and the Marine Management Organisation—are responsible for delivering some of the UK’s most complex and high-profile environmental policies: water resources and governance; marine and fisheries management; agricultural transition; and climate and nature recovery. ICF leads Defra’s Monitoring, Evaluation and Learning (MEL) Facility, a £104 million delivery partner contract that combines methodological rigour, policy insight, and digital innovation to embed learning at the heart of environmental policymaking.

Challenge

To strengthen its evidence function, Defra required a commissioning route that could consistently secure high-quality analytical and evaluation support while keeping delivery timelines tight. The MEL Facility was therefore established as an assured, value-for-money mechanism that gives buyers rapid access to a wide range of specialist expertise, without the delay of running individual procurements for each assignment. This model enables Defra teams to mobilise the right capability quickly, maintain robust quality standards, and ensure timely, policy relevant delivery across a diverse and fast-moving portfolio.

Alongside this, Defra is seeking to strengthen how it generates, synthesises and applies evidence to meet statutory targets and respond to heightened public and regulatory scrutiny. Drawing on support from the MEL Facility, Defra is developing a more coherent and scalable MEL system that can bring together insights from evaluations, environmental monitoring and research, and apply them consistently across programmes and portfolios.

We work with a supply chain of over 30 specialist organisations, ensuring each assignment draws on the right technical, environmental, social, and economic expertise. Together we apply the full range of recognised evaluation methods, tailored to the complexity of Defra’s interventions:

• Evaluations: Delivering high‑quality process, impact and value‑for‑money evaluations using advanced analytical techniques and methods. This includes applying the latest tools for evidence synthesis and complexity‑appropriate evaluation to support faster, more robust decision‑making.
• Environmental monitoring: Designing and implementing monitoring systems that draw on modern digital technologies, automated data pipelines, and geospatial or sensor‑based solutions to track environmental change and programme outcomes with greater precision and timeliness.
• Environmental research and surveys: Generating robust qualitative and quantitative evidence through fieldwork, remote sensing, smart survey instruments, stakeholder engagement, and primary research.

Each project follows a structured MEL design and delivery process, with methods adapted to the nature of the work—evaluation, monitoring, or research. Designs are supported by participatory theories of change, integrated MEL frameworks, and modern, technology‑enabled data‑collection and analysis solutions. This ensures evidence is generated, synthesised and translated into actionable policy insight with clarity and consistency across programme, portfolio and strategic levels.

We modernised MEL delivery through the AI-enabled MEL Management System, combining a secure portal, Power BI dashboards, and AI-assisted workflows. This enables real-time tracking of projects, KPIs, and learning outcomes across the Facility.

Machine learning and large language models (LLMs) are used to integrate qualitative and quantitative evidence at scale—automating synthesis, improving consistency, and accelerating insight generation. Applications include fisheries community resilience analysis and AI-enabled document review to assess uptake and impact of tree-planting.

Results

Since its launch in 2024, the Defra MEL Facility has delivered significant impact:

• 186+ projects delivered or in delivery across Defra and its arm’s‑length bodies, providing rapid access to specialist evidence and analytical expertise.
• Robust evaluations shaping policy reform in water governance, marine management and agricultural transition, supporting more effective and transparent delivery.
• Evidence contributing to major environmental reforms, including the UK’s nature protection and restoration agenda and proposals to build a more resilient and accountable water sector.
• Stronger, more coherent marine policymaking, with evidence enabling joined‑up, accountable, and ecosystem‑based approaches.
• Support for the transition to nature‑friendly, resilient farming, providing timely insights to inform post‑Brexit agricultural reform.
• Greater transparency and performance oversight through real‑time dashboards and digital reporting tools.
• Enhanced cross‑agency learning, supported by shared frameworks, consistent evidence standards and reduced duplication.

Through the Defra MEL Facility, we’re helping Defra embed evidence, innovation, and continuous learning into environmental policymaking—supporting better decisions today and more resilient outcomes for the future.
