Prof. Obed Lungu

Prof. Obed Lungu Obed Isaac Lungu is a Professor of Soil Chemistry and Fertility at the University of Zambia. In addition to academic duties at the University, he is a Soil Management Specialist at the Golden Valley Agricultural Research Trust, a public-private partnership Research and Development institution in Zambia. Professor Lungu has held senior academic positions outside Zambia, including that of Associate Professor of Soil Science at the Limpopo University (1992-1993) and Vice Rector (1993-1995) and Rector (1995-1996) of Madzivhandila College of Agriculture in Limpopo Province of South Africa. He earned a B. Agric Sci. from the University of Zambia, an MSc degree in Soil Science from the University of Newcastle Upon Tyne, UK and a PhD degree in Soil Science from the University of California, Davis, USA.

His research focuses on soil quality improvement, with particular emphasis on amelioration of soil acidity and optimization of nitrogen and phosphorus fertilization. He is currently working on loading of food crops with micronutrients (selenium and zinc) in order to increase their intake in diet not only for the general good health of the population but particularly for the mitigation of AIDS. This work is being conducted under a broader regional project “ Strengthening HIV/AIDS and Food Security Mitigating Mechanisms Amongst Smallholder Farmers in Botswana, Lesotho, Namibia and Zambia”.  The research aims to establish the relationship between micronutrient status of the soil and content in food crops.

Lungu’s work on soil quality improvement in Southern Africa has contributed to some continental policy developments. His co-authored paper “African Soils: their productivity and profitability of fertilizer use” that was read at the African Fertilizer Summit 9-13th June 2006, Abuja, Nigeria  contributed to The Abuja Declaration on Fertilizer for a Green Revolution in Africa by African Heads of State at the Summit. His research on selenium in soil and food has demonstrated a new context of viewing HIV and AIDS, not only as a medical problem but as a complex link involving agriculture, food, medicine and nutrition. He proposes that selenium and indeed any micronutrient intake through food is the most equitable strategy for improving the nutrition of chronically undernourished people.

His publications range from theses, journal articles, occasional papers, special papers reports and commentaries. He has authored and co-authored many articles in refereed journals and special papers. Lungu has also authored chapters in books and written more than sixteen papers published in refereed conference proceedings. He regularly publishes popular extension education articles in the field of soil and water management for sustainable agricultural production.

Lungu has  served as a consultant for a number of governmental, non governmental and international agencies such as the FAO, World Agroforestry Centre (ICRAF), PELUM, SADC/ EU Land and Water Management Applied Research & Training Programme, USAID, Food Security Project/Michigan State University, CARE Mozambique, ASP/DANNIDA Tanzania, Alliance for a Green Revolution in Africa (AGRA) Soil Health Programme, ADB/Ministry of Agriculture Zambia, Soil Fertility Consortium of Southern Africa, Leadership for Environment and Development, Agricultural Innovative Fund. He is co-founder of the Kafuku Farm Institute (, an organization seeking to promote sustainable and profitable agricultural practices amongst smallholder farmers in Zambia. In 2002 the institute was recognized with an award for its work in the community by the Times Newspapers of London.

He is actively involved in community empowerment outreach programmes and was a former Board member (vice chairperson) for Women for Change in Zambia and currently patron of the Zambia Rainwater Harvesting Association. Ed. AJFAND
