- Analyse des modes d'élevage et des ressources pastorales dans la commune rurale de MadiamaKodio, Amadou; Adama, Ballo; El Hadj, Meriam; Abaye, Azenegashe Ozzie (2001)La commune rural de Madiama est confrontée à des conflits liés à lexploitation des ressources naturelles limitées dont les stratégies d'utilisation actuelles (agriculture, élevage et pêche° sont inadaptées (ESPGRN, 1996). La commune couvre 16.700 ha dont 1.073 ha seulement d'espace pastoral. En effet, il faut 3 à (ha, voire 14 ha en saison sèche pour entretenir un UBT. Ces conditions ne permettent plus à la commue de jouer son rôle de zone d'attente des grand troupeaux transhumants de passage pour les bourgoutières du Delta Intérieur du Niger. Ce qui est source de nombreux conflits entre agriculteurs et éleveurs. En saison sèche, tous les troupeaux sédentaires, et une partie des troupeaux semi transhumants et transhumants se retrouvent sur le terroir de la commune pour exploiter les résidus de récolte et les maigres pâturages. En hivernage, l'essentiel des animaux se déplacent à la recherche de pâturage dans les communes voisines ou même en terroir du Burkina Faso. Les connaissances des ressources pastorales et les mouvements des troupeaux sont indispensables à la mise en place d'un plan de gestion localement durable.
- Analysis of the modes of breeding and pastoral resources in the rural community of Madiama, Mopti Region, Republic of MaliKodio, Amadou; Adama, Ballo; El Hadj, Meriam; Abaye, Azenegashe Ozzie (2001)Available also as a conference paper.

- Experience CALS 2022: Cooking with the Hokies the Celebration of Agriculture, Food and CultureAbaye, Azenegashe Ozzie (2022-04-01)“Food is not just about fueling the body. It’s about giving and taking and sharing and nurturing and communicating. When you share food with someone, especially with people who are unlike you culturally, you gain a greater understanding of them and yourself. It’s not just a meal. It’s communion with your fellow citizens stuck together on this big ball of dust floating in the universe”. Anthony Bourdain. Food and culture are highly integrated in every global society. Food is the central core of every celebration: birth, wedding, major calendar events (New Year), and religious holidays. Thus, in the food lab, all recipes across the grain and horticultural crops discussed in class will be used to make festival foods (foods prepared during major holidays and celebrations).
- Exploring the Potential Use of Teff as an Alternative Grain Crop in VirginiaAbaye, Azenegashe Ozzie (2022-10-07)Teff (Eragrostis tef (Zucc.)) is an annual, warm-season cereal crop most notable for its gluten-free, nutrient-packed seed. With more than a million tons of teff produced annually in Ethiopia and production growth in the United States, interest in teff has led to the development of this study. Experiments were conducted in two geographical regions of Virginia (Blacksburg and Steeles Tavern) to determine the grain production potential of two teff varieties (brown and white). Physical tests were used to evaluate the quality of the final product. Generally, bread and cake volume decreased as the percentage of teff increased. Teff flour was best suited for use in cookie and biscuit products compared to cakes and bread. Overall, both experiments (field and laboratory) demonstrated the potential of teff as an alternative grain crop in Virginia. However, additional research is needed to overcome problems associated with establishment, harvest, threshing, and processing.
- Goji: Chinese medicinal plant that may be a promising alternative crop for VirginiaWelbaum, Gregory E. (2019-12-24)This was an invited talk at Minzu University in Beijing China about research to produce goji berry, a popular medicinal herb, in Virginia rather than import it from China.
- Recognizing Women’s Needs: A Key in Agriculture Production and Food SecurityAbaye, Azenegashe Ozzie (Virginia Tech Libraries, 2018-11-08)The Women and Gender in International Development discussion series offers an opportunity for scholars and practitioners to share their research and knowledge surrounding gender and international development. Dr. Ozzie Abaye will talk about her research in the developing world. Women have been denied access to both financial and land resources throughout history. Yet, they contribute more than their share to agriculture and food security on a daily basis. Through USAID-ERA (United States Agency for International Development – Education and Research in Agriculture (USAID-ERA) a project that aimed (delivered) to revitalize the agricultural sector through education, research, and discovery, and outreach, implemented several agricultural interventions at the community, private, and public sector levels using the land-grant model. Some of the agricultural interventions focus on those that have the explicit goal of improving food security by supporting women at the village levels. Two of such projects are a small-scale silage project designed to conserve forages to feed small ruminants during the dry season and the introduction mungbean, to diversify the diets mainly composed of cereal crops. Mung bean is a greater source of protein and fiber when compared to its cultural counterpart, cowpeas, and other staple grains. The presentation will focus on the initial contribution of these two women targeted projects on perceived women’s health and productivity.

- Silvopastures: SVAREC update, Kentland results, and SPAREC studiesPent, Gabriel J.; Fike, John H.; Downing, Adam K. (2017-08-02)Silvopasture is the purposeful and managed integration of trees, forages, and livestock. With appropriate management, these intensive, integrated management systems create beneficial interactions among the system components that result in more efficient resource use and greater economic output over the life of the system. Benefits of silvopastures can include increased forage yield or quality, reduced animal stress, improved tree growth and quality, greater farm product and ecosystem diversity and a number of conservation gains (Fike et al. 2004)
- Study in the USA: ArkansasAbaye, Azenegashe Ozzie; Reiter, Mark; Ziegler, Peter (2022-02-17)A key driver of the Arkansas trip was experiential learning, hands-on and face-to-face experience with industries involved in food production, marketing, and consumption. Emphasis will be on teamwork and acquiring skills necessary to solve real-world problems. The overall objective of the trip was to give insights into differences in production practices between Arkansas and Virginia. Differing experiences allow students to connect the dots between classroom learning, experiences already learned within Virginia, and a new cropping system that varies drastically.
- Study in the USA: Arkansas, California and ArizonaAbaye, Azenegashe Ozzie; Reiter, Mark (2022-03-16)The COVID pandemic has had an impact on higher education, especially on experiential learning experiences. Due to the COVID pandemic, we canceled several study abroad programs. To provide the much-needed hands-on and face-to-face experience, we created an experiential learning course titled “Study in the USA" with variable destinations. The key driver of the course is experiential learning, hands-on and face-to-face experience with industries involved in food production. It is the purpose of this course to give insights into differences in production practices between the western states like Arizona and California and mid-Atlantic states like Virginia. Specific objectives of the course are: 1) Provide students with a baseline understanding of experiential learning so they can apply academic learning in work settings appropriate for their career plans, 2) Engage students in developing skills and competencies relating to producing food in the time of COVID- and climate change, and 3) Develop a deeper understanding of challenges faced by people who are engaged in all aspects of agricultural enterprises. While in California and Arizona, the course focused on water issues including water scarcity, availability and utilization of water, and most importantly, the politics of water. The course also explored labor issues specifically associated with vegetable production, indigenous farming, and way of life. Overall, the course provided far more than academics to help students recover from the pandemic, it provided a perfect platform for social interaction which was missing for several years due to the COVID pandemic.
