Urban nature is discussed and explored in this set of course material offered online as part of the MIT OpenCourseWare initiative. The course was originally taught by Professor Anne Whiston Spirn in fall 2012 and, as the site notes, explores “the mutual influences of ideas of nature, theories of city design and planning.” On the site visitors can read over the syllabus to check out the list of readings as well as the assignments. Some of the readings are available as free downloads and there really are some great works here. The Assignments are sure to pique the curiosity of those with a penchant for urban affairs and the truly adventurous may complete them on their own.
