How the Lancet Countdown illuminates a new path to climate-resilient health systems

Reda SadkiGlobal health

The 2025 Lancet Countdown report has begun to acknowledge a critical, often-overlooked source of intelligence to build climate-resilient health systems: the health worker. By including testimonials from health workers alongside formal quantitative evidence, the Lancet cracks open a door, hinting at a world beyond globally standardized datasets. This is a necessary first step. However, the report’s framework for action remains a traditional, top-down model. It primarily frames the health workforce as passive recipients of knowledge—a group that must be “educated and trained” because they are “unprepared”, rather than build on existing evidence that points to health workers as leaders for climate-health resilience. The 2025 report confirms that climate change’s assault on human health has reached alarming new levels. Yet, within this sobering assessment lies a quiet but potentially pivotal shift. For the first time, the Countdown’s country profiles integrate direct testimonials from frontline health workers, explicitly acknowledging their “lived experiences as valuable …

Agentic AI revolution and workforce development

The agentic AI revolution: what does it mean for workforce development?

Reda SadkiArtificial intelligence

Imagine hiring an assistant who never sleeps, never forgets, can work on a thousand tasks simultaneously, and communicates with you in your own language. Now imagine having not just one such assistant, but an entire team of them, each specialized in different areas, all coordinating seamlessly to achieve your goals. This is the “agentic AI revolution” —a transformation where AI systems become agents that can understand objectives, remember context, plan actions, and work together to complete complex tasks. It represents a shift from AI as a tool you use to AI as a workforce that you collaborate with. Understanding AI agents: More than chatbots When most people think of AI today, they think of ChatGPT or similar systems—you ask a question, you get an answer. That interaction ends, and the next time you return, you start fresh. These are powerful tools, but they are fundamentally reactive and limited to single …

Learn health, but beware of the behaviorist trap

Reda SadkiGlobal health, Theory

The global health community has long grappled with the challenge of providing effective, scalable training to health workers, particularly in resource-constrained settings. In recent years, digital learning platforms have emerged as a potential solution, promising to deliver accessible, engaging, and impactful training at scale. Imagine a digital platform intended to train health workers at scale. Their theory of change rests on a few key assumptions: On the surface, this seems sensible. Mobile optimization recognizes health workers’ technological realities. Multimedia content seems more engaging than pure text. Assessments appear to verify learning. Incentives promise to drive uptake. Scale feels synonymous with success. While well-intentioned, such a platform risks falling into the trap of a behaviorist learning agenda. This is an approach that, despite its prevalence, is a pedagogical dead-end with limited potential for driving meaningful, sustained improvements in health worker performance and health outcomes. It is a paradigm that views learners …

Rethinking Workplace Learning and Development

Learning-based complex work: how to reframe learning and development

Reda SadkiAbout me, Global health, Interviews, Published articles, The Geneva Learning Foundation

The following is excerpted from Watkins, K.E. and Marsick, V.J., 2023. Chapter 4. Learning informally at work: Reframing learning and development. In Rethinking Workplace Learning and Development. Edward Elgar Publishing. This chapter’s final example illustrates the way in which organically arising IIL (informal and incidental learning) is paired with opportunities to build knowledge through a combination of structured education and informal learning by peers working in frequently complex circumstances. Reda Sadki, president of The Geneva Learning Foundation (TGLF), rethought learning and development (L&D) for immunization workers in many roles in low- and middle-income countries (LMICs). Adapting to technology available to participants from the countries that joined this effort, Sadki designed a mix of experiences that broke out of the limits of “training” as it was often designed by conventional learning and development practitioners. He addressed, the inability to scale up to reach large audiences; difficulty to transfer what is learned; …
