The African Potato Association (APA) is a non-profit organization formed in 1983 and its core
objective is to promote the production and the use of potato and sweetpotato in Africa.
Currently, most APA members are scientists and practitioners drawn from 20 African countries,
including North Africa. Every three years, the APA holds a scientific conference to review
progress in potato and sweetpotato research in Africa. The conference also provides an
opportunity for scientists to interact with other stakeholders in the sector through exhibitions,
presentations and panel discussions and share knowledge, experiences and lessons learned.
Kenya was selected to host the 9th Triennial APA Conference because of the critical role that
potato and sweetpotato play in contributing to food security. It is against this background that
Kenya’s State Ministry of Agriculture, the National Potato Council of Kenya and the International
Potato Center have joined hands to organize and host this international event. The theme of the
conference is Transforming Potato and Sweetpotato Value Chains for Food and Nutrition
Security.
The five major sub-themes are:
1. Appropriate policies for germplasm exchange, food security and trade in Africa,
2. Getting seed systems moving,
3. Major advances in breeding and crop management
4. Innovations in post-harvest management, processing technologies and marketing systems
5. New evidence concerning nutritional value and changing behaviors.
The papers from the conference will be published by CABI and the posters uploaded on their
website.
The program is presented first in a summary version, without all of the details for the oral
presentations, and then in a more detailed version, listing the titles and presenters of all oral
presentations. After the title, there is an abstract number provided in parentheses to facilitate
locating the abstract in the accompanying abstract book.
Introduction to the Themes of
the 9th Triennial APA Conference

APA 2013 KEYNOTE SPEAKERS
Strategies to improve poor seed potato quality
and supply in Sub-Saharan Africa
Paul Demo is a potato specialist with 23 years of experience working
in Sub-Saharan Africa and currently the International Potato Center’s
(CIP) Senior Country Liaison Scientist for Malawi. His long-term
research interest is on how to solve the problem of shortage of quality
seed potato using innovative seed production systems and public-
private sector partnerships. He also has substantial experience in the
selection of adapted potato varieties for different end users and potato
crop management. Prior to joining CIP, he played a leading role in
developing the potato program in his native country of Cameroun
(1990-2003). From 2003 to 2006, he served as SSA Regional Potato
Expert for Eastern and Central Africa. Since 2007, he has been based in
Lilongwe, Malawi, leading CIP’s program in Malawi and designing the
programs for CIP’s potato work in Mozambique and Angola. CIP’s work
in Malawi, supported by Irish Aid and the Scottish government, focuses
on the development of a sustainable quality seed potato multiplication
system, variety selection and public-private partnerships approach to
build viable value chains.
Was small ever beautiful? Moving local
sweetpotato seed systems to scale in Sub-
Saharan Africa
Margaret McEwan is a social scientist with over 30 years working
in rural development, farming systems research, household food
security and nutrition in eastern and southern Africa. She has a strong
interest in how to engage multi-disciplinary teams and stakeholder
partnerships in ensuring improved livelihoods and nutrition outcomes.
Her current research interests explore the interaction between
agricultural technology and society, and how differing perceptions of
seed quality influences the institutional arrangements for emerging
sweetpotato seed systems in Tanzania and Ethiopia. These findings will
lead to an understanding of how to retain the quality of sweetpotato
planting material when seed systems are used at a larger scale.
Margaret joined CIP at the end of 2008. Prior to this, she worked with
FAO, SIDA, and AUSAID.

Role of Intellectual Property in Facilitating
Technology Transfer
Ian Barker is head of Agricultural Partnerships at the Syngenta
Foundation. He has over 25 years of experience of R&D management
in plant pathology and diagnostics technology. Before joining the
Foundation, he was Head of Seed Systems for the International Potato
Center (CIP) in Nairobi, improving the provision of affordable quality
planting material for smallholders in developing countries. Ian chaired
CIP’s public-private partnership committee, and has implemented
innovative partnerships using private sector investment and know-
how to increase the availability of quality potato seed in East Africa.
Previously, he worked as Head of Diagnostics at the UK Food and
Environment Research Agency, developing and commercializing novel
diagnostic methods for plant and animal diseases as well as food and
feed contaminants. Ian graduated from Wye College, University of
London, and holds a PhD from the University of Exeter, UK. Within the
Foundation, he is currently responsible for leading a program aimed at
assuring access to quality seed of improved varieties for small-holder
farmers.
Disease Management, especially viruses in
potato and sweetpotato
Dr Jari Valkonen is the professor of plant pathology at the University
of Helsinki, Finland. His areas of expertise are in molecular virus-plant
interactions and pathogen defense of plants. Most of his research
and published works concern viruses of potato and sweetpotato and
aim especially to deeper understanding of the antiviral mechanisms.
Since the early 1990s, his work has included collaboration with CIP
and since middle 1990s East African institutes, such as Makerere
University, Uganda, and Mikocheni Agricultural Research Institute,
Tanzania. An important aspect of the studies is also education of
young scientists. Under his supervision, over 30 doctoral theses have
been completed or are on-going. Among these, eight are focused on
viruses in sweetpotato or cassava in East Africa and five are authored
by East African scientists. Valkonen is currently involved in the Seed
Potato Development Project in Tanzania supported by the Finnish
government and coordinated by CIP.

Advances in sweetpotato breeding from 1992 to
2012
Robert Mwanga has over 30 years of experience working with
national and international sweetpotato research and development
teams. He led the Uganda program on multiple-trait improvement of
sweetpotato, breeding for increased beta-carotene (pro-vitamin A) in
the HarvestPlus Program in Sub-Saharan Africa (SSA), and the Vitamin
A for Africa (VITAA) initiative to alleviate vitamin A deficiency (VAD)
in SSA. In Uganda, his research team released 20 cultivars, of which
NASPOT 1, NASPOT 11, NASPOT 9 O (Vita) and NASPOT 10 O (Kabode),
have been widely promoted and disseminated, the latter two for
combating VAD in SSA countries. Dr. Mwanga has led, since 2009,
regional sweetpotato breeding work in East and Central Africa under
the Sweetpotato Action for Security and Health in Africa (SASHA)
project of CIP, applying modern methods of plant breeding, such as
accelerated breeding, and developing resistance to weevils and viruses
by conventional and biotechnology means to improve the efficiency of
sweetpotato breeding in the region.
On the road to potato processing in African
tropical highlands
Prof. dr ir Anton J. Haverkort coordinates potato research projects at
Plant Research International – Wageningen University and Research
Centre in the Netherlands and is an extra-ordinary professor of Crop
and Soil Science at the University of Pretoria (South Africa).
After completing his Master’s degree, he worked for many years for
the International Potato Centre in Turkey, Rwanda, Peru and in Tunisia
to improve potato production through agronomy, breeding and
crop protection. He obtained his PhD at University of Reading (UK)
in mathematical modelling of the influence of temperature and solar
radiation on potato development and growth in tropical highlands.
At Wageningen University, he coordinates research on the
development of a cisgenic marker free late blight potato (www.
durph.nl). Additionally, he carries out research on data management
(ontology) in the French fries supply chain and leads sustainable
potato production projects in eight countries on four continents aimed
at the efficient use of resources (land, water, energy) and value creation
through trade and processing.
He has published over 75 scientific papers, 5 books and hundreds
of conference papers, book chapters, columns and articles for
professional journals. He is a chairman or member of various potato
committees in the Netherlands dealing with seed certification and
genetic modification and was secretary general of the European
Association of Potato Research. He travels frequently for potato
research and consultancy for the industry, and international
governmental and non-governmental organizations.

Improvement of processing technology research
and utilization of sweetpotato and its derived
foods
Professor Xie Jiang is a food storage and processing specialist at
Institute of Agro-products Processing Science and Technology of

Project, which is managed by the University of California at Davis.

Assessing Nutritional Value and Changing
Behaviors Regarding Sweetpotato Use in
Sub-Saharan Africa
Jan Low is an agricultural economist with over 20 years of experience
working in sub-Saharan Africa. Her long-term research interest is on
how to successfully integrate nutritional concerns into agricultural
research and development, with a special focus on micronutrient-
enhanced (“biofortified”) staple food crops. She also has considerable
experience and interest in agricultural policy, safety nets, poverty
analysis, and seed systems. She has designed, implemented, and
analyzed numerous household surveys and is knowledgeable in
database management. After serving 4.5 years as CIP’s regional leader
in SSA, Dr. Low is now leading the 10 year Sweetpotato Initiative
launched in October 2009 to enhance the lives of 10 million African
families in 10 years through exploiting the potential of sweetpotato
to reduce poverty and undernutrition. The Sweetpotato Action for
Security and Health in Africa is the foundation project supporting core
research for development work for this multi-donor, multi-sector effort.
Dr. Low is the current president for the APA.
Addressing the changing consumer behaviour
in the South African market
Etienne Booyens currently is the Marketing Manager at Potatoes South
Africa and has occupied the position for the past six and a half years,
but has been involved in the potato and fresh produce industry for
almost 18 years. Apart from his position as Marketing Manager, he is
also Managing Director of Prokon (a Fresh Produce Quality Control
Company on all the Fresh Produce Markets) and a Trustee of 5-a-Day
Trust as well as a member of the International Potato Group.
He completed several courses and a degree in Business Management,
Marketing and International Marketing at the Post Graduate School
at the University of Pretoria, the University of South Africa (UNISA)

FIELD TRIPS
Vitamin A deficiency (VAD) contributes to blindness, disease, and premature death in Sub-Saharan Africa.
Pregnant or lactating women and young children are particularly at risk of VAD. Thus pregnancy is an
opportune time to reach women with nutritional and health interventions to lower their risk of VAD and
enhance the survival and growth of their infants.
The Mama SASHA project integrates agriculture and nutrition into antenatal health care services
(ANC) to maximize benefits of OFSP, an important source of energy and beta-carotene (pro-Vitamin
A), especially for mothers and young children. The challenge is to introduce OFSP into an area where
traditionally farmers grow cream and yellow-fleshed varieties. The project aims to provide solid evidence
for the effectiveness of this innovative approach. It is expected this will have positive impacts on the
consumption of Vitamin A-rich foods and use of ANC services.
The project uses community health workers (CHWs) supported by APHIA Plus (USAID) to encourage
pregnant women to seek early ANC and postnatal care services (PNC). In addition, CHWs form and run
community-level pregnant mothers clubs (PMCs) with monthly dialogue sessions on nutrition and health.
During each ANC visit, ANC nurses provide improved nutrition counseling along with vouchers, which
the women use to obtain OFSP planting material from trained vine multipliers (DVMs) for planting and
eventual consumption of OFSP roots. Extension workers follow up the women benefitting in their homes
with agronomic advice.
To evaluate the program’s impact, an equal number of intervention and control sites were randomly
selected from among eight health facilities. The four intervention sites receive the full range of nutrition,
outreach, and health services along with the vouchers. At the four control facilities, just normal ANC clinic
services are provided (no additional nutrition counseling or vouchers).
Since April 2011, over 2800 pregnant or lactating women have received vouchers with over 70%
redeeming them for vines, far exceeding the project’s goal of 900 women.

Kabondo area in Homa Bay County is the leading producer of sweetpotatoes consumed in Kenya,
contributing over 60% of the national consumption, which translates into more than $37.5 million Ksh
farm-gate value. Over 7,000 farmers are involved in production activities with at least an average of 0.5
acres each committed to the crop. Other than the traditional varieties, farmers have been introduced to
high yielding orange-fleshed sweetpotato (OFSP) varieties which are favoured for their high nutritional
value, disease tolerance, early maturation period and diverse value addition opportunities.
However, there exist challenges of low productivity per unit area primarily driven by use of recycled and
unclean planting material; poor agronomic practices; over-reliance on rain-fed production; inadequate
investment in research on new and improved varieties as well as unsustainable marketing structures.
To address this, the USAID-funded Kenya Horticulture Competitiveness Project (KHCP) has expanded
the rapid seed multiplication system in collaboration with Kenya Agricultural Research Institute (KARI),
Ministry of Agriculture, Kenya Plant Health Inspectorate Service (KEPHIS), private laboratories and major
input suppliers. Marketing challenges are being addressed through scheduled production, collective
marketing and capacity building on agri-business skills.
The Kabondo Sweet Potato Marketing and Cooperative Society (KSPMCS) is the only known sweetpotato
cooperative in the country. KHCP seeks to build management and marketing capacity of the cooperative
to enable membership benefit from the marketing opportunities in the sweetpotato value chain and
consequently improve their livelihoods through consolidation of produce for wholesale traders.

Whereas potato has gradually become a priority crop for the Kenyan population with enormous potential
as both a food security as well as a cash crop capable of raising the livelihoods of smallholder farmers,
availability of high quality input seed remains a key constraint in the development of the potato sector
in Kenya. Moreover the potato processing sector faces severe shortages of high quality and appropriate
varieties. This hinders the expansion and profitability of the processing sector. In partnership with
other key partners, including GIZ PSDA (Promotion of Private sector Development in Agriculture), GTIL
(Genetics Technology International Transfer) and KARI (Kenya Agricultural Research Centre) Tigoni, and CIP
(International Potato Center) scientists have successfully adapted a technology of producing high quality
mini-tubers in a soil-less system known as“aeroponics”.
Kisima Farm is located on the northern slopes of Mount Kenya. This farm specializes in crop production,
mainly barley, wheat, and flowers; it has 10,000 acres and it is highly mechanized. Since the initiation
of the potato project in 2009, Kisima Farm has produced over 4,000 tons of certified seed in isolated
fields with proper rotations for further distribution to trained seed multipliers and ware producers. Over
400,000 mini tubers have been realised.
This innovative system has allowed Kisima Farm to produce mini-tubers at far lower cost, reducing the
number of field generations required to multiply seed and thus reducing the impact of serious soil-borne
disease constraints such as bacterial wilt. The rapid migration and establishment of this technology from
the International Potato Center at Kisima Farm has significantly contributed to the development of the
potato industry in Kenya.

The Agricultural Development Corporation (ADC) Molo is a center of seed potato production, storage
and distribution. Potato is a priority crop for the Kenyan population with enormous potential for
food security and as a cash crop capable of improving the livelihoods of smallholder farmers. A major
constraint to improving potato production is a shortage of quality seed potato. A rapid seed potato
multiplication system was established at ADC Molo consisting of a tissue culture lab and aeroponics
system to produce minitubers for field multiplication of certified seed potato. In partnership with
CIP (International Potato Centre) scientists, GIZ PSDA (Promotion of Private sector Development in
Agriculture), GTIL (Genetics Technology International Transfer) and KARI (Kenya Agricultural Research
Centre) Tigoni, ADC Molo is successfully producing high quality, certified seed potato.
The field trip will also include a visit to Tusibe, an association of women entrepreneurs. Through
successive access to and repayment of loans of ever growing value, they developed and grew their
bakery business based on products made from sweetpotato flour. This dynamic group of women is
responsible for all components along the value chain, from sweetpotato production in the field, to
milling the roots for flour, baking and marketing.
