Banana and Plantain Systems

Bananas drawg
Grown by smallholder farmers, bananas and plantains are major food staples and two of the leading cash crops, both in the East African Great Lakes zone and the West African humid lowlands. Diverse banana cultivars are grown for a number of uses, including brewing (juice bananas), cooking and roasting, as well as sweet dessert bananas. Banana starch, flour, and chips are processed banana products whose markets are yet to be fully developed. Because of its cash crop status, farmers are more likely to adopt high-level management technologies in order to intensify production and yet sustain the natural resource base in the systems. Clearly, much progress can be realized with more profitable and sustainable banana systems.

Since the 1970s, reports of low and declining banana yields have been widespread. Some have attributed this phenomenon to constraints such as soil degradation, pests, poor crop husbandry, and drought. In this project, the hypothesis is that these constraints are, to a large extent, interlinked. Although each constraint can, on its own, potentially cause serious yield decline, the complex interactions between a number of them compound yield losses.

The overall purpose of the banana and plantain project is to enhance the performance of banana and plantain systems within smallholder farms in sub-Saharan Africa.

The main project objectives are:

  • To increase knowledge on ecosystems, social systems, and commodity chains related to banana and plantain production in
  • To research ways to improve profitability of banana and plantain systems in Africa
  • To improve the quality of banana- and plantain-based food products

Erostus Njuki Nsubuga: Lessons on partnership

R4D Review interviewed Erostus Njuki Nsubuga, the chief executive officer and managing director of Agro-Genetic Technologies Ltd (AGT), to get his insights on the IITA-AGT partnership. AGT is the first and only private commercial tissue culture (TC) laboratory in Uganda and so far the biggest single supplier of banana TC planting material in East and Central Africa. It produces up to 8 million tissue culture plantlets per year, of which 1 million are banana plants.

Nsubuga wants to see AGT become well established and profitable by increasing its capacity to provide the region with quality TC planting material at affordable prices and introducing other services such as plant and soil analysis, and produce organic fertilizers. His dream is for AGT to become a one- stop shop that provides total solutions to farmers.

Nsubuga was born in Uganda and spent his early years there. Because of the war, he and his family had to move to other countries in Africa and Europe. He started living on his own at 16, studying in Europe and USA for 24 years to obtain an MSc (Agriculture) and MBA (International Marketing). He worked in international companies and managerial positions for over 20 years but his dream was always to come back, to help his mother who had survived all the wars, to sustain himself and his family, and to contribute to the development of his people and country.

What made you establish AGT?
I had completed one contract and was about to start a new job when I decided to start a TC laboratory at my house. I employed and trained two people to produce TC plants out of my kitchen while I was traveling. At that time (2001–02) banana and coffee wilt diseases were spreading like wildfire in Uganda. It was easy to start with these two crops as there was great demand for disease-free planting material to reduce the spread of diseases and restore healthy plantations. Over time, using my own finances, AGT built a state-of-the-art TC facility and we grew significantly. Our technical team now includes five university graduates and a retired professor. Degree students from Makerere University have been doing their internships at AGT’s laboratory with their programs embedded in our production line.

How did the AGT and IITA partnership come about?
It started when Dr. Thomas Dubois called me out of the blue. IITA was looking for a commercial enterprise to start testing and producing its endophyte-enhanced plants. Under a mutual agreement, AGT and IITA have worked on fine-tuning the enhancement of TC plants with endophytes. We identified and established on-farm trials together, using the same farmers. In the short run, IITA assisted us with laboratory chemicals and AGT also benefited from publicity. In the longer run, production of endophyte-enhanced TC material would be greatly beneficial to AGT and other commercial producers in the region. Now that the original project has expired, we are trying to get this unique product commercialized to supply farmers facing high pest and disease pressure.

Please give some insights on public-private collaboration.
Collaboration can be very important in developing and disseminating research products. For IITA, it has forced them to think commercially from the onset. A good example has been the experimental protocol for endophyte inoculation. After piloting it in my lab, IITA quickly abandoned the use of a nutrient solution in favor of fertilizer-amended soil along the lines of the system used in commercial nurseries. Such partnerships should be developed as early as possible, especially for a technology such as this. This would help AGT to build up its technical, human, and financial capacity to take on the research products once they reach commercialization. Also a very clear agreement has to be drafted and this is sometimes a balancing act.

How could IITA improve its relationship with the private sector?
AGT indicated to IITA that it was open to other research products but wanted to be involved at an early stage. This is what we call a demand-driven research agenda where the consumer is sure of getting research products through private sector involvement. We are now backstopping a socioeconomic study looking at full commercialization of our nurseries in Uganda and Rwanda. At present AGT sells mainly through NGOs and institutions. Direct marketing to farmers would be better.

What lessons have you learned from the partnership with IITA and others?
It is great that research organizations such as IITA have realized the role of private sector involvement in agricultural research and in the product value chain. Such partnerships are relatively new and we still have much to accomplish. Personally, I feel many governments and international research institutions, even IITA, are working too much for the donors, not the farmers. We should tell the donors what needs to be funded. More impact assessment is needed on some research products.

Any suggestions for future collaboration or collaborators?
I hope IITA can do more demand-driven research by including the private sector in the development of research products as early as possible with specific roles for each partner clearly defined.

What do you think makes AGT successful?
I have a professional approach and commitment, with many years of experience in agriculture and entrepreneurship and good relationships, local and international. AGT started when diseases such as banana bacterial wilt and coffee were at their peak, so I was in the right place at the right time.

How else could development organizations and private entities such as AGT help farmers and consumers?
AGT is getting farmers involved in production, distribution, and training by establishing banana nurseries and demonstration gardens owned by local farmers. The farmer then becomes the AGT distributor for that community and the nursery the focal point for training others in modern agricultural practices.

What is your dream for Uganda?
Uganda is the second largest producer but seventy-fifth in banana exports. The Government and all development partners should industrialize this crop and thus lift many out of poverty.

Any thoughts about the world food crisis, food security, GMOs, or development in general?
African countries are the poorest in the world today with many problems. We urgently need biotechnology tools, including GMOs, to address problems. We should not waste time blaming others for creating poverty and hunger but make efforts ourselves to get out of the rut. I still have far to go but I am contributing to the well being of farmers in Uganda and the whole region.
