Keith was raised on a family farm in Michigan and earned a BSc from University of Michigan School of Natural Resources in Ann Arbor, and a Masters from Framingham State University, International Education. Keith's current work focuses best practices for clean energy transitions and international standards to support inclusive and sustainable development. Keith's career begin with USAID, living overseas for 24 years in Latin America and Africa while working on projects that involved renewable energy systems, protected area planning, and community engagement with forest management and biodiversity conservation. Current research interests include: causal analysis to improve understanding of drivers of change in land cover and linkages to ecological services and human welfare; identification of effective mechanisms to promote beneficial “land-use change” (improved management of natural resources and implementation of nature-based solutions); integrated, agro-silvo-pastoral-urban production systems; and practical approaches to support adaptive management and continual improvement. Keith contributes to voluntary international standards initiatives addressing global barriers to green growth: carbon accounting, net zero guidelines, food security, indirect effects, leakage, monitoring and evaluation. Current projects support Net Zero World just transitions, the Biofuture Clean Energy Ministerial, standards for Circular Economy (ISO TC323), Food-Energy-Water nexus international research network, best practices for engaging stakeholder in sustainability assessment; uncertainties and potential bias inherent in choice of a reference or counterfactual scenario; representation of land management and disturbance regimes in modeling; and effective governance approaches to promote more sustainable practices.
