Episode 14: Katherine Foster - Principles for Impactful Systems Innovation

Logo of Adopter - the marketing agency for deep tech and climate adaptation.

Episode summary

Katherine Foster, Innovative Finance Lead at EIT Food and World Economic Forum Fellow, discusses systems innovation, blended finance, and the scaling of food and nature-based solutions on Episode 14 of Scaling Green Tech, a podcast by Adopter.Foster's theory of change is grounded in the belief that systems are dynamic and interdependent, and that the goal is to design for complexity rather than control it. Drawing on a 35-year career spanning Canadian diplomacy, the Climate Chain Coalition, the Green Digital Finance Alliance, the UN Task Force, and the World Bank, she argues that innovation does not follow a linear path from invention to market. Scaling requires adaptive financial mechanisms, collaborative frameworks, and integration of non-financial forms of value - including natural capital, social capital, and indigenous expertise. Foster also reflects on her work advancing regenerative and resilient food systems, how AI and digital tools are reshaping agricultural finance, and why true scaling happens when local expertise connects with global frameworks.This episode is relevant for food system investors, blended finance practitioners, regenerative agriculture programme designers, climate innovation accelerator managers, and policymakers working on agri-food value chain finance, carbon credit methodology, and EU Knowledge Innovation Communities.

Guest profile

Katherine Foster is the Innovative Finance Lead at the EIT Food Vertical (European Institute of Technology) and a World Economic Forum Fellow. Foster's career spans over 35 years across diplomacy, climate policy, digital finance, and systems innovation. She previously served as Executive Director of the Green Digital Finance Alliance and Sherpa to the UN Secretary General Task Force of Digital Financing of the SDGs. Earlier roles include work in the Canadian Foreign Service, EU Climate-KIC Innovation Lead and AFOLU Business Development Lead. She is an experienced university lecturer and innovation program and tech transfer manager.EIT Food is one of the European Union's Knowledge Innovation Communities (KICs). It brings together partners across research, entrepreneurship, and education to address food system challenges. The organisation is currently funding regenerative landscape projects in Spain and Poland, with three additional projects planned. It has created a dedicated Innovative Finance Lead role to advance financial innovation across agri-food systems.

Key takeaways

  • Foster's theory of change is built on the principle that systems are dynamic and interdependent, and that innovation is not linear. Her core argument is that organisations should design for complexity rather than try to control it - building adaptive frameworks that can absorb political shifts, financial cycles, and changing definitions of value over time.
  • Foster uses a "four Gs" framework - gender, geography, groups of stakeholders, and generations - to evaluate whether AI and data systems capture the full range of relevant information. Without data across all four dimensions, she argues, AI risks perpetuating the same barriers and gaps it is meant to resolve.
  • Foster distinguishes between indigenous voices and indigenous expertise. She argues that local and indigenous knowledge is not a consultation input but a form of technical authority - essential for designing solutions that fit specific environments, from Canadian forest fire management to Namibian microfinance operations.
  • The Capitals Coalition, where Foster serves as a commissioner, is working to integrate natural capital, social capital, and human capital into value frameworks. Foster argues that current accounting and valuation systems are short-term and regulatory-focused, and do not capture the broader value that ecosystems and communities provide.
  • Foster advocates for blended finance models that bring all actors in a value chain together as financial participants, so the burden of transition does not fall on individual farmers or communities. She frames blended finance not as a fixed structure but as a transitional mechanism that shifts over time as different funding sources come into play.
  • AI has the capacity to fill critical data gaps - from MRV on forest coverage to matching methane reduction formulas to cattle types through AI biometrics. However, Foster warns that AI trained on existing systems will reproduce existing limitations unless it is governed carefully and designed to include data that current frameworks miss.
  • Foster calls for redefining scaling beyond the linear adoption curve. She argues that systems-level scaling is adaptive and networked, shaped by local context, and requires a full set of financial, data, and policy tools that overlap so that gaps in one area do not stall progress across the whole system.
