Clemson, Africa universities work on Zimbabwe vegetable production

CLEMSON – Clemson University and Africa University in Zimbabwe have joined hands to help small farmers in the region improve vegetable production, protect the environment and fight hunger.

Africa University, supported by the United Methodist Church, is in the eastern highlands of Zimbabwe near the city of Mutare bordering Mozambique, according to Gloria McCutcheon, entomologist at Clemson’s Coastal Research and Education Center at Charleston.

“It’s a country filled with beautiful people and smiling faces amidst an HIV/AIDs epidemic and poverty,” she said. “Many of the people are not receiving the nutrients they need in the form of vegetables.”

She is principal investigators of a project that began in 2004 and will run through 2009 with support from a $45,000 grant from the United States Department of Agriculture’s Foreign Agricultural Service. Powell Smith, Clemson Extension vegetable entomologist at Edisto Research and Education Center at Blackville is co-principal investigator.

“The goal is to help the small farmers increase yields of leafy greens, be good stewards of the environment and produce foods without excessive pesticide residues,” said McCutcheon.

During a December 2004 visit to Africa University, McCutcheon taught students, technicians and farmers how to identify the families of insects that are important in biological control of plant pests such as the diamondback moth.

“There are more insects that are beneficial to us than those that are pests,” she said. “Many of the beneficials are inconspicuous, move very fast and often spend part of their lives inside pest insects as parasites.” Common natural enemies of plant pests include ladybird beetles, ground beetles, pirate bugs, lacewings, mantids, spiders, parasitic wasps and flies, plus fungi, viruses and bacteria.

Many of the vegetables grown in Zimbabwe, including leafy greens, are similar to what is grown in South Carolina, and the corresponding complex of pests and beneficials is similar. Clemson investigators will search for appropriate beneficial organisms that can be imported to the United States and tested to see whether they can be released here safely to help control pests.

“It’s possible we may also learn some production techniques that could be useful,” said McCutcheon, who observed some women, “who are the real farmers in Zimbabwe,” spraying crushed marigolds on vegetables to fight pests during a visit to some villages near Mutare.

She believes there is much to learn about traditional agricultural practices, and much of the knowledge is in Africa. She points out that it was African slaves who taught the principles of rice production to plantation owners in Charleston in the 1800s, resulting in tremendous wealth for the landowners.

The Clemson-AU partnership grew out of a conversation between McCutcheon and the Zimbabwe ambassador during his visit to Florence, S.C. in the 1990s.

“He had universities with similar missions as Clemson University to extend official invitations to me,” she said. One of the contacts was from M. N. Mphuru, an entomologist who is now deputy vice chancellor at AU.

While McCutcheon was on sabbatical leave, Jim Salley, associate vice chancellor of the African University Office of Institutional Advancement, arranged for her to travel to AU to visit with the Faculty of Agriculture and Natural Resources. Together they developed the collaboration now under way.

“The Clemson/AU partnership is a wonderful collaboration between two institutions that have a shared commitment to help the human condition,” said Salley. “This work is one of the ultimate empowerment stories, a program that will help people to help themselves.”

The Clemson-AU partnership has already produced a graduate student. Walter Manyangarirwa, a member of the agriculture faculty at AU, is a Ph.D. candidate in the Department of Entomology, Soils and Plant Sciences at Clemson.

During the summer he will spend his time at Edisto REC working with Smith and McCutcheon. Manyangarirwa will return to AU next year, where he will teach students from 25 countries in Africa.

For more than 25 years McCutcheon, one of a handful of African-American researchers with a doctoral degree in the field of entomology, has conducted outreach and research programs to include students of color who have the potential to pursue graduate degrees.

“One of my former students, Shani Gourdine, is the first African-American to be a medical entomologist with the U.S. Navy,” she said. “It’s very gratifying to see students go out into the world and give back to their communities and to their country.”
