Nature is not a collection of parts but a web of connections

Connected Nature - Jacqueline McGlade · 38:25 · Video: Gresham College · Watch at the source

In short: We often view nature as a series of isolated systems—forests, oceans, and species existing independently. However, Jacqueline McGlade reveals a deeper reality: a biogeophysical planetary network where molecular clocks, plant biochemistry, and migratory behaviors are inextricably linked. Understanding these hidden threads is essential to navigating our changing world.

Professor Jacqueline McGlade’s work explores the profound interconnectedness of our planet, moving beyond simple biology into the realm of biogeophysical connections. Her research highlights how these links operate at multiple scales, from the molecular level—such as the biochemistry found in plant toxins and medicines—to the large-scale behaviors of animals and plants across continents. By examining these systems, McGlade illustrates how human activities like economic development and climate change do not just affect single species but ripple through these complex planetary networks. McGlade’s perspective is informed by four decades of experience at the intersection of science, society, and policy. Her career includes high-level leadership roles, such as serving as Chief Scientist for the United Nations Environment Programme (UNEP) and Executive Director of the European Environment Agency. These positions allowed her to oversee global assessments like the Global Environment Outlook and provide secretariat support for major bodies including the IPCC and IPBES. Her expertise bridges the gap between hard data—like environmental informatics and statistics—and practical, community-based conservation. A key nuance in her approach is the integration of local and indigenous knowledge with modern science. For example, she has worked directly with the Maasai tribe in Kenya to develop sustainable livelihoods based on a circular economy and green growth. By training indigenous people to map their lands and sacred sites, McGlade emphasizes that understanding nature requires honoring both scientific data and the lived experiences of those who inhabit it. Her work suggests that resilience depends on recognizing these intertwined impacts: where inequality, pollution, biodiversity loss, and climate change form a single, complex narrative.
