Snapshot: Permaculture – Alternative Agriculture, part 3

Leave a comment

Last year, students of the RCC Environmental Studies Certificate Program had the opportunity to attend a three-day workshop with Jochen Koller, Diploma Permaculture-Designer and Director of the Forschungsinstitut für Permakultur und Transition (FIPT). Students gained an insight into the ethics and design principles of permaculture, the diverse spheres of activity, and the practical possibilities. In this short series of posts, students reflect on their experiences at the workshop and on permaculture as an interdisciplinary approach to thinking, planning, and designing.


“A Winter Home for Bats”

By Luna Benítez Requena

The Hummelhof (German for “bumblebee farm”) is already home to cows, sheep, bumblebees, chickens, and cats—not to mention a herbary and several fruit trees. It’s newest residents? Bats, of course.

Bats, the only mammals able to fly, are an important component of ecosystems, performing crucial roles that include pollination and seed dispersal, as well as consuming pests. Nonetheless, despite conservation efforts, many bat species have become endangered because of slow reproduction rates and loss of habitat due to increasing anthropogenic activity. For example, our building practices have had a severe impact on the spaces bats typically inhabit for shelter, and their food has become scarce as a result of human activities like monoculturing and crop spraying to tackle pests.

The Hummel family, which runs the Hummelhof, recently decided to build a bat tunnel, a sort of winter residence, on their premises. Students of the Environmental Studies Certificate Program spent half a day there last year learning about life at the farm and assisting in their various projects, including sustainable farming, planting specific tree species to cultivate habitats for bees, and the bat tunnel, which was almost ready when we arrived.

The tunnel consists of a deep trench, inlaid with concrete blocks, and topped with a compost film and a layer of sand. The bricks lining the trench will ensure that water can be collected to maintain cool temperatures of 2–8°C—ideal conditions for bats. It is the work of citizens like those at the Hummelhof  whose work has seen certain bat species removed from the endangered list—proof that small steps can make a big difference.
