Introduction
Edward S. Cheppa (born 1938) is an American economist and environmental scientist recognized for his pioneering work on the economic valuation of ecosystem services. His interdisciplinary approach bridged environmental science, public policy, and economics, influencing national and international conservation strategies during the late twentieth and early twenty‑first centuries. Cheppa has authored over 120 peer‑reviewed articles and several influential books, and he served as a senior advisor to the United Nations Environmental Programme for more than a decade.
Early Life and Education
Birth and Family Background
Edward Samuel Cheppa was born on March 12, 1938, in San Antonio, Texas. He was the eldest of three children born to Margaret (née Lawson) and William Cheppa, a textile mill manager. Growing up in a modest household, Cheppa developed an early fascination with the natural world, often spending evenings in the family's backyard garden and exploring nearby wetlands with his siblings.
Primary and Secondary Education
Cheppa attended local public schools, excelling in mathematics and biology. At Jefferson High School, he was a member of the science club and later served as president of the economics club. In 1956, he received a scholarship to study at the University of Texas at Austin, where he earned a Bachelor of Science in Biology with a minor in Economics.
Graduate Studies
After completing his undergraduate degree, Cheppa enrolled in a joint master's program at the University of California, Berkeley, receiving a Master of Science in Environmental Science in 1961. His thesis examined the impact of urbanization on the Rio Hondo watershed. During this period, he began to integrate economic analysis into ecological studies, an approach that would define his later career.
Doctoral Research
Cheppa pursued his Ph.D. at Yale University, completing his dissertation in 1965 under the supervision of Dr. Richard J. Smith. His doctoral research focused on the valuation of wetlands for flood control and water purification. The study introduced a cost‑benefit framework that became a reference point for subsequent environmental valuation work. He was awarded the John M. Oakes Award for Distinguished Graduate Research upon graduation.
Academic Career
Early Faculty Positions
Cheppa began his teaching career as an assistant professor of Environmental Economics at the University of Michigan in 1966. Over the next five years, he established a research group focused on the socioeconomic impacts of ecological degradation. His 1971 paper on the economic costs of deforestation in the Amazon Basin was widely cited and prompted further research into tropical ecosystems.
Professorship at the University of Washington
In 1971, Cheppa accepted a full professorship at the University of Washington, where he founded the Center for Ecosystem Economics. The center attracted scholars from diverse disciplines, including biology, geology, and public policy. During his tenure, Cheppa mentored over thirty doctoral candidates, many of whom later became leading experts in environmental economics.
Visiting Scholar Roles
Throughout the 1980s and 1990s, Cheppa held visiting scholar positions at several prestigious institutions. He spent a sabbatical year at the World Bank in Washington, D.C., where he consulted on the economic implications of large‑scale hydropower projects in Africa. In 1993, he was invited to serve as a visiting professor at the University of Cape Town, South Africa, contributing to the development of environmental policy frameworks for the region.
Retirement and Emeritus Status
Cheppa retired from active faculty duties in 2003 but continued to hold an emeritus position at the University of Washington. Even after retirement, he remained a frequent speaker at international conferences and an advisor to governmental agencies.
Contributions to Environmental Economics
Valuation of Ecosystem Services
Cheppa's most enduring contribution lies in the quantitative valuation of ecosystem services. He developed methods for assigning monetary values to natural functions such as carbon sequestration, water purification, and pollination. These methodologies have been integrated into cost‑benefit analyses for environmental projects worldwide.
Policy Integration
He was instrumental in promoting the inclusion of environmental valuation in national budgeting processes. Cheppa advised the United States Environmental Protection Agency (EPA) during the formulation of the 1980 Environmental Impact Statement guidelines, ensuring that economic analyses of ecological impacts were systematically incorporated.
Cross‑Disciplinary Collaboration
By fostering collaborations between ecologists, economists, and policymakers, Cheppa advanced a holistic understanding of environmental problems. His 1990 edited volume, Ecosystems and Economies, compiled case studies demonstrating the practical application of valuation techniques across different ecosystems.
Educational Initiatives
Cheppa authored several textbooks used in university courses worldwide. His 1985 book, Principles of Environmental Economics, remains a foundational text. He also designed a graduate seminar series on the economic impacts of climate change, which was adopted by universities in North America and Europe.
Consultancy and Advisory Work
Beyond academia, Cheppa served as a consultant for numerous non‑governmental organizations. In 1988, he advised the World Wildlife Fund on the economic justification for the protection of the Mekong Delta. His analysis contributed to the successful establishment of conservation easements in the region.

Personal Life
Cheppa married Linda R. Thompson, a marine biologist, in 1963. The couple has two children, Dr. Maya Cheppa, a climate scientist, and Dr. Robert Cheppa, a policy analyst. Outside academia, Edward Cheppa is an avid sailor and has participated in several long‑distance sailing competitions. He is also an amateur photographer, frequently capturing images of wetlands and forest ecosystems that appear in his publications.
Legacy and Impact
Edward S. Cheppa's interdisciplinary methodology has reshaped the way governments and organizations evaluate environmental projects. His valuation frameworks are routinely employed in environmental impact assessments and in the design of market‑based instruments such as carbon trading schemes. The Center for Ecosystem Economics, which he founded, continues to operate as a leading research institute, training new generations of environmental economists.
Cheppa’s influence extends beyond the United States. His advisory roles in Africa, Asia, and South America helped shape environmental policy in emerging economies, ensuring that ecological considerations were incorporated into national development plans. His work laid the groundwork for the modern field of environmental economics, bridging the gap between natural sciences and socioeconomic analysis.
In addition to his scholarly contributions, Cheppa has been recognized for his mentorship. Over 30 doctoral students who trained under him have gone on to hold prominent positions in academia, government, and the private sector, further amplifying his impact on the field.
