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.

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.

The conference participants include representatives from NARS, international agricultural research centers, advanced laboratories and universities from developed and developing countries, United Nations’ agencies, governmental and non-governmental organizations, donor and development organizations, businesses in the ag-biotechnology and food processing industries.

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.

“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.  

Project to save farmers from bogus agricultural commercial products launched

Most small holder farmers in sub-Saharan Africa are struggling to make ends meet and are always on the lookout for ways to boost their production. And they are even more desperate now in the face of unpredictable weather due to climate change.

Unfortunately, they sometimes fall prey and loose huge sums of their hard earned money to unscrupulous companies selling them ‘miraculous’ products that promise to increase their yields but which turn out to be fake or sub-standard and do  not live up to their claims.  

Moreover, the regulatory bodies established to control these products and safeguard farmers’ investments are often poorly funded, poorly equipped and the regulations are not up to date to include some of these new innovative products coming into the market such as bio-fertilizers and bio-pesticides.

To address this, the International Institute of Tropical Agriculture (IITA) recently launched the second phase of the Commercial Products (COMPRO-II) project that aims to benefit two million smallholder farmers in East and West Africa by providing information on which agricultural products are genuinely effective to boost their production among the myriad currently available in the market.

IITA's Director General Dr Sanginga speaking during the project launch. 

 “We have all these products in the market which, like the witchdoctors’ potions, promise to solve all the farmers’ problems. Our concern therefore is that our poor small-scale farmers are using their little hard earned money to pay for products that do not produce results. So we first set out to understand the problem then see how to help them,’ said Dr. Nteranya Sanginga, Director General for the International Institute of Tropical Agriculture (IITA) during the launch that was held in Dar es Salaam, Tanzania on 16 May 2012.  

‘Under phase I of the project, with a grant from the Bill &Melinda Gates Foundation, we screened over 100 such products in the market to see which ones are useful. And out of these only three were found to be really effective,” he said.

The three were Rhizobium inoculants for legumes, mycorrhizal inoculants for tissue-culture banana, and fertilizer seed coating of for maize.

Rhizobium and mycorrhizal are bio-fertilizers that make use of useful micro-organisms that are naturally found in the soils. Rhizobium is a bacterium that converts the free nitrogen in the air into a form that plants can absorb from the soil. Mycorrhizal fungus assists plants to absorb nutrients from the soil and strengthen their resistance to soil-borne pests such as nematodes.

Fertilizer seed coating for maize on the other hand, avails essential nutrient to the crop on germination making it grow better, have better root development and become better established.

The second phase will primarily focus on creating awareness and disseminating to farmers these tried and tested quality products to increase their production and building the capacity of national systems to continuing screening such products coming into the market.


“The project will engage with and support national institutions to put in place systems to continue screening these products to check their quality. This will ensure farmers are not wasting money on fake products that do not work,” said Dr Prem Warrior, a Senior Program Officer at the Bill & Melinda Gates Foundation.

At the end of the project, more farmers are expected to confidently use these products because their safety, efficacy, and quality will be ensured through institutionalized regulatory and quality assurance mechanisms.

“We want to make farmers’ life better. Using some of these productions that we have checked and ascertained their quality together with other good farming practices such as use of fertilizers and improved varieties, they can get better yields of maize, soybean and banana and improve their lives,” said Bernard Vanlauwe, IITA Director for Central Africa and the project team leader.

The project is targeting small-holder farmers in six African countries: Tanzania, Kenya, Nigeria, Ethiopia, Ghana, Uganda, and Tanzania.
