Researchers and partners discuss value addition in cassava through cassava-based feeds

Participants in the workshop.

More than 50 experts on cassava, nutrition and livestock, the private sector—represented by producers and feed millers—and representatives from donor groups, the Nigerian Federal Ministry of Agricultural and Rural Development, and development partners, came together in IITA this week to discuss how cassava residues or by-products such as cassava peels can be used in industry and to add value to the industrial cassava value chain.

The meeting, held at IITA 28-30 October, aimed to come up with a roadmap for developing a cassava-based feed system for livestock, an action plan for Nigeria, and pilot projects that would serve as models in Africa.

The meeting was organized by IITA, GCP21, the Nigerian Federal Ministry of Agriculture and Rural Development, the CGIAR Research Programs on Roots, Tubers and Bananas, Livestock and Fish, and Humidtropics, and the private livestock feed sector.

As part of Nigeria’s Agricultural Transformation Program, the cassava transformation plan seeks to create a new generation of cassava farmers, producers, and processors oriented towards commercial production to generate  cassava for specific value-added chains. The plan aims to turn the cassava sector in Nigeria into a major player in the local and international production and processing arena for flour, starch, sweeteners, ethanol and dried chips markets through private sector-led value-added chains.

Traditionally small farmers discard the peels that are left as waste near processing locations for feeding their animals (poultry, goats and pigs). Few attempts have been made to establish a nutritionally and economically sustainable cassava-based feed system using local products to replace imported products in the feed industry.

Enhanced production under the Cassava Transformation Plan will produce over 2 million tonnes of additional cassava by-products each year, offering a unique opportunity to support a cassava-based feed system at an industrial scale.

The use of cassava-based feeds in Nigeria will bring several benefits including cutting down on maize imports, most of which are used as feeds for livestock, according to the researchers.

“Africa imported maize worth US$4.63 billion in 2011 of which Nigeria’s feed industry alone accounted for 1.2 million tons worth about $350 million,” says Dr Iheanacho Okike, Country Representative for the International Livestock Research Institute (ILRI) based in Ibadan.

“If we use cassava peels for livestock feeds, for instance, we will be able to reduce the amount we spend on maize importation, and more importantly reduce the competition between man and livestock for maize,” he added.

Efforts to transform Nigeria’s agriculture have raised the production of cassava to more than 50 million tons per annum, with several factories now processing cassava to products such as flour, gari, glucose, and ethanol. This growing demand and processing of cassava is also churning out cassava residues including cassava peels to the environment.

Dr Peter Kulakow, IITA Cassava Breeder, said the “use of cassava peels in livestock
is a win-win situation for both agriculture and the environment. It is basically converting waste to wealth,” he added.

Dr Claude Fauquet, Director of GCP 21, said the use of cassava-based feeds would widen the opportunities for cassava farmers and help alleviate poverty.

According to him, Africa, being the lead producer, needs to take advantage of the crop, by creating/tapping into value addition.

Fauquet also said Nigeria produces 50% of the world’s cassava although poverty levels in the country remained high when compared with Latin America and Asia.

The Minister of Agriculture and Rural Development, Dr Akinwumi Adesina praised IITA for its continuing work on cassava and for hosting the conference.

He said the government had concluded arrangements to establish additional ethanol and starch processing industries in three cities across the country to create more value addition for cassava.

Represented by Dr Martin Fregene, Senior Technical Advisor, the minister said on completion, the factories would be producing cassava residues which if converted to feeds would create additional jobs and incomes for the country.

According to him, the nation’s agricultural transformation plan aims to create about 3.5 million jobs through the establishment of agro-based industries by 2015.

Cassava more popular among the older populations in major cities in Tanzania

Over a half of the population in the three major cities in Tanzania eat cassava but nearly everyone eats maize.Furthermore, the hardy root crop, was found to be more popular among the older people who preferred  it in the form of ‘ugali’ made from its flour while the young population mostly ate it boiled.

There is therefore a huge potential to increase the market for cassava in the country by getting more people to eat it especially the urban youth says Dr Adebayo Abass, a value chain specialist from the International Institute of Tropical Agriculture (IITA). 

Dr Abass was speaking at a recent training on standards for cassava flour in East Africa for cassava processors from Kigoma, Pwani and Mwanza regions held at the Lake Zone Agricultural Research Institute (LZARD) in Mwanza. The five East Africa countries harmonized their standards for cassava and potato and their products to facilitate cross-border trade.

Dr Abass said the study commissioned by IITA and conducted by Consumer Insight, asked 1,464 people in the major cities in Tanzania the important crops in their daily food. Over a half of them, 53% said they ate cassava compared to 100% of maize. 65% of them said they ate it boiled cassava while 67% consumed it as a stiff porridge ‘ugali’ made from the flour.

 “Looking at age differences, a majority of the young people between 18-24 consumed boiled cassava while among the older generation, most preferred to eat ugali made from its flour. Most of the younger people (70%)said they would like to eat cassava ugali, if the flour was white and not smelly” he said.

According to the researcher, ugali made from some traditional cassava flour is smelly while the modern processing method developed by IITA through and tested in collaboration with the Ministry of Agriculture, Food Security and Cooperation (MAFC) and the Tanzania Food and Nutrition Center (TFNC) and other partners gives non-smelly cassava ugali.

According to the study, conducted between May and July 2013, the region with the highest consumers of cassava was Mwanza and mostly in the form of cassava ugali. It was least popular in Arusha possibly because the cassava flour available in the market is grey in color (33%).

Looking at quality issues, the study found that 44% of the population wanted the cassava flour to be finely milled, 33% said they did not want smelly flour and 30% wanted it white in colour. And when asked where they wanted to buy their flour, majority said at the kiosks in the neighborhood. Only 9% said the supermarkets. Two thirds of the people interviewed also said they found it difficult to find the cassava flour because it was not available in the kiosks.

The processors spread the dried cassava mash on a raised platform to keep off livestock and dust to avoid contamination of the floor and preferably on dry black plastic bags which trap heat hastening the drying process.

Abass further advised the processors, “Looking at the whole population, majority want the flour to be white and finely milled. No one wants grey and smelly flour. That is how you should process your flour. Many of you have been targeting supermarkets, now you need to start considering the kiosks– the small shops within the residences.”

Dr Abass also added that a majority of those interviewed said that they did not want the cassava and maize flours mixed together by the processors. They prefer to buy each separately and mix at home themselves as they wish. They also preferred the packing to be in one kg packets.

The training was conducted by researchers from IITA and Tanzania Bureau of Standards (TBS) with funds from Association for Strengthening Agriculture Research in East and Central Africa, (ASARECA).

IITA DG calls for a “Brown Revolution” for a “Green Revolution” in Africa

The push for a “Green Revolution” in Africa to increase agricultural production for food and economic development will not bear much fruit if adequate attention is not paid to managing soil fertility in the continent.

 Global Cassava Partnership conference in Kampala, Uganda.

According to Dr Nteranya Sanginga, IITA Director General, Africa cannot achieve a “Green Revolution” without first having a “Brown Revolution”. He noted that the current application of 8 kg/ha of soil nutrients, whether organic or inorganic fertilizers, was very low and was a major setback to the continent’s vision of adequately feeding itself.

Dr Sanginga spoke at the Global Cassava Partnership meeting currently taking place this week in Kampala, Uganda, that brought together over 400 international scientists from all over the world to strategize on how cassava can play a bigger role in economic development by exploiting the diverse uses of this hardy crop. Cassava performs well under harsh conditions, such as poor soils and drought.

The conference was launched by the Honourble Minister of Agriculture, Animal Industry and Fisheries, Hon Tress Bucyanayandi who noted that frequent droughts and floods as a result of climate change were one of the leading causes of food insecurity in the world today with millions of USD going into emergency food aid.

He noted that cassava was a crop that performs well in drought conditions and is becoming an important food security crop. He therefore urged the researchers gathered at the conference to develop solutions to some of the challenges facing the production of the crop in the region such as Cassava Mosaic Disease (CMD) and Cassava Brown Streak Disease (CBSD), the two diseases wreaking havoc on the crop’s production. 

Participants following workshop proceedings

Dr Eugene Terry from Transfarm Africa noted that a number of efforts to transform cassava were already underway in the region starting with the development and deployment of improved better yielding varieties by IITA. He noted that over 80% of the new varieties released by national programs in Africa had incorporated these varieties released in the 1970’s and dubbed TMS series.

He said there were many challenges facing the transformation of the crop that needed to be tackled through research including control of pests and diseases and the need for early maturing and drought tolerant varieties. On marketing issues, he said there was need to research on better organization of value chains, better infrastructure support and how to reduce transaction costs.

Dr Sanginga on his part told the conference participants that while much investment had gone into developing high-yielding cassava varieties that were resistant to some of the major pests and diseases, the gains achieved cannot be realized if these varieties are grown in poor soils.

He said it was unfortunate that cassava had been tagged for many years as a poor man’s crop that does not require much input such as fertilizers. He argued that the crop harvested as much nutrients from the soil as other crops and that these nutrients needed to be replenished. It also requires nitrogen, phosphorous, and potassium similar to other crops.

“Nutrient use in cassava has been very minimal as it is considered a poor man’s crop. However, if we are talking about cassava transformation, about increasing cassava production not only for food but also for commercial use, we must change these wrong perceptions. If we think of growing cassava in soils that are too poor for other crops such as maize,” he said, “then, we are missing the other half of the equation.”

The African Union has recommended for the countries in the continent to increase application of soil nutrients to 50 kg/ha of nutrients combining both organic and inorganic fertilizers.

The Global Cassava Partnership for the 21st Century (GCP21) conference is taking place on 18–22 June 2012 in Kampala, Uganda. GCP21 consists of 45 member institutions working on research and development of cassava, a staple crop relied on by more than 700 million people worldwide. The ultimate goal of the partnership is to improve cassava productivity through scientific research and development.

Sanginga drums up support for IITA’s Southern Africa hub

 The IITA Director General, Dr Nteranya Sanginga, was last week, from 11 – 15 June 2012, in Zambia, to meet different partners of the institute to explore ways to strengthen relationships and support each other in efforts to find solutions to hunger and poverty in the country and beyond.

The partners welcomed the move by IITA to invest in first class research facilities and increase the number and diversity of scientists working in Lusaka, Zambia, its regional hub for Southern Africa and serving 13 countries in the region

Meeting with AfDB team

The hub is one of four that the institute is working through as it decentralizes its activities to have more impact as part of its ambitious plan to get 20 million people out of poverty in Sub-Saharan Africa in the next ten years as spelt out in its refreshed strategy. 


The hubs are in Nigeria for the West, Tanzania for Eastern, Zambia for Southern and Democratic Republic of Congo for Central Africa.

Tackling succession crisis in agricultural research
Sanginga said the institute was going to especially focus on building capacity of researchers from national research institutes and institutions of higher learning.

He noted that many countries in Africa were heading towards a crisis as the current experienced civil servants in the agricultural sector who were retiring did not have qualified predecessors to take over. 

At a media briefing

“In Zambia, in Congo, in Kenya and in many other African countries, the situation is the same. We have scientists at the prime of their career being forced to retire because they have attained retirement age of 50 – 55 years. On the other hand, there are very few experienced staff to take over from them. So at IITA we are exploring how to make use of the knowledge and skills of these retirees and how to build the capacity of young researchers and attract the young people to agriculture,” he said.

This was welcomed by the Acting Director of ZARI Dr Moses Mwale and the Dean of the School of Faculty of Agriculture Sciences, University of Zambia, Dr Mick Mwala and their colleagues.

Crop diversification

Dr Sanginga also noted that there was need for African countries to diversify their staple crops particularly to avoid over reliance on maize. This was supported by country representatives of FAO, Mr Adrianus Spijker and Africa Development Bank (AfDB), Dr Freddie Kwesiga who noted that over-reliance on maize as a food staple and income crop in Zambia was not sustainable particularly in the face of climate change and dependency on rain-fed agriculture.

They identified cassava as one crop they were keen on promoting as it was a hardy crop with uses that went beyond just being a food crop.

Dr Sanginga assured them that IITA had many years of working along the cassava value chain and would lend its expertise to support the country in its diversification efforts.

He gave an example of Nigeria where the policy of including 20% cassava flour was saving the country millions of US dollars from reduced wheat importation and was creating jobs for thousands of young people.

FAO country representative, Mr Spijker noted that IITA and FAO had achieved significant success in dealing with Cassava Mosaic Diseases (CMD) in DRC. He said IITA’s new disease-resistant varieties distributed all over the country, with support from FAO and other partners, had averted a major disaster. He was therefore more than happy to collaborate with IITA to make a difference in Zambia.

Sanginga said the institute was also focusing on strengthening its research on Natural Resource Management, and partnership with National Agricultural Research Systems (NARS) for better impact.   

Sanginga was accompanied by the IITA director for Southern Africa, David Chikoye and Steve Boahen, and Alene Arega, the Country representatives for Mozambique and Malawi respectively.

In his short busy program in Zambia, Sanginga also made brief presentations at the University of Zambia, at the FAO offices, had a media briefing in addition to holding a meeting with all IITA staff in Zambia.  

The day cassava ruled

“Are all these made from cassava?” this was the most popular question of the day by people from all walks of life invited to the Mozambique Cassava Day held in Nampula, Mozambique in November 2010.

There was a wide array of foods made from cassava and its derivatives, cassava cakes, cupcakes, cookies, biscuits, bread, pies, samosas, chin chins, cocktail tit bits, doughnuts, egg rolls, meat balls, pancakes, croquettes, sausage rolls, and puddings to be sampled. All the other food items were made from 100% high quality cassava flour except for the bread which had wheat flour added.

Speaking on behalf of the governor of Nampula, the Provincial Director of Commerce and Industry, Ilidio Marfres, said the crop had immense potential to develop the province. He was happy to note that the province’s strategic plan included exploring the use of cassava as a source of raw material for industries.

He challenged them to explore the wide range of uses and opportunities offered by cassava that go beyond making their staple food, ‘karakata’ – a paste made from its flour and ‘mathapa’ – cassava leaves cooked in coconut - to fight poverty and develop the region.

Richard Okechwuku, Deputy Project Manager of UPoCA project, noted the great strides made in the province in one year following a series of trainings conducted on cassava processing by the project.

“We were here last year, at a time like this, to train on the various products that can be made from cassava. Today, we are impressed to see so many products as a result of it.
”
The day was organized to create awareness on the versatile hardy tuberous crop by IITA’s UPoCA project, Mozambique’s Center for Promotion of Agriculture (CEPAGRI), the Mozambican Agricultural Research Institute (IIAM) and the Provincial Office of Agriculture in Nampula (DPA).

It brought together farmers, private sector, non-governmental organizations, and government organizations and aimed at creating awareness on cassava utilization and lobbying for much-needed government support
