Areas of Interest
Cropping systems, agroecology, rye cover crop and agricultural research and rehabilitation in Somalia.
My research has focused on cropping systems involving crop rotations, rye as a cover crop, and alternative crops. I have taught several courses annually (AGRO3203w: Environment, Global Food Production, and the Citizen, AGRO3305: Agroecosystems of the World, AGRO4013: World Food Problems, AGRO4605 (Strategies for Agricultural Production and Management, and AGRO5999: Agroecosystems Analysis Field Course) and chaired the Campus Committee on Student Behavior for five years. I serve on the board of directors of the Somali Agricultural Technical Group (SATG) and Somali Family Services (SFS). I served as coordinator of the Agricultural Industries and Marketing (AIM) undergraduate degree as well as the International Agriculture Minor, on the board of directors for the Minnesota Institute for Sustainable Agriculture (MISA) and the Northwest Minnesota Regional Sustainable Development Partnership, and on the advisory board of the Healthy Foods Healthy Lives (HFHL) initiative.
Through a collaborative UofMN-SATG partnership, I have been actively engaged in helping define the Somali Ministry of Agriculture’s strategic plan and in the formation of the Agri-Business Incubation. Center at Afgoi, Somalia. I made numerous visits to Somalia since 2013. See www.satg.org for more information about SATG.
In Spring 2009 and Spring 2010 I rode a bicycle 12,000 km across 10 African countries. Using satellite phone technologies, I co-taught courses while in Africa (Food and Agriculture from Cairo to Cape Town at 10 mph). Visit my blog site to hear more stories and see amazing photographs of the people, food and agroecosystems he encountered. http://paulporter.cfans.umn.edu/
In Fall 2011 I co-taught the course 'Food and Agriculture from Buenos Aires to Lima at 10 mph' while riding a bicycle 6,000 km through four South American countries. Visit:http://eatbikegrow.ning.com for stories related to those agroecosystems.
