Mopan Maya ecological engineering: Emergy evaluation of design strategies for sustainable ecosystem restoration and human subsistence Many indigenous groups traditionally manage local ecosystems to provide for familial needs while protecting their surrounding environment, and such practices can aid in understanding efficient and sustainable ecosystem design strategies.  The Mopan Maya of southern Belize practice an agroforestry system that conserves the surrounding rainforest while utilizing natural forces to drive change through nine distinct successional stages, including three herbaceous, two shrub, and four forest stages.  This presentation discusses Mopan traditional ecological knowledge (TEK), quantitatively describes the plant community and associated soil ecology of successional stages, and presents embodied energy (emergy) evaluations at the individual field, system stage, and whole system levels.  Emergy analysis is a useful tool for evaluation of resource utilization, productivity, and sustainability of agroforestry methods as it considers all system components on a common unit basis of solar origin.  Design tenets of Mopan TEK offer tools to provide for familial needs while concurrently promoting a biotically-varied rainforest ecosystem.  As Mopan techniques originate in highland areas, their success in lowland forests after migration over a century ago provides an example of potential applicability and adaptability of such design strategies in regional conservation and restoration efforts.  Refreshments will be served.

We’re Turning 100!

To mark our centennial in the fall of 2024, the Maxwell School will hold special events and engagement opportunities to celebrate the many ways—across disciplines and borders—our community ever strives to, as the Oath says, “transmit this city not only not less, but greater, better and more beautiful than it was transmitted to us.”

Throughout the year leading up to the centennial, engagement opportunities will be held for our diverse, highly accomplished community that now boasts more than 38,500 alumni across the globe.
