World Pulses Day: on the trail of Yakina the bean

The humble bean can make a big impact: the Pan-Africa Bean Research Alliance (PABRA) is using an innovative approach to fight malnutrition, improve food security, stimulate the private sector and empower women in Burundi. In honour of World Pulses Day, we follow the journey of one bean, ‘Yakina’, as it travels from the beanstalk to the mouths of hungry children.

Have you ever heard of a bean corridor? It's not the aisle between rows of beanstalks being grown in a greenhouse, and it's also not what toddlers create when they'd rather play with their food than eat it.

Bean corridors are the paths taken by beans as they are produced, distributed and consumed. The term encompasses regional and national trade routes as well as all parties involved in a bean's journey from the field to the plate. Beans have the potential to fight malnutrition while improving food security, stimulating the private sector and promoting gender equality.

In order to accomplish all of this, however, you first need the right variety of bean: one that can withstand extreme weather, is tailored to local conditions and contains important trace elements such as iron and zinc. Most importantly, it should also produce high yields. Together with partners such as Switzerland, the Pan-Africa Bean Research Alliance (PABRA) has been on the ground in 32 African countries for more than two decades, working on cultivating bean varieties with exactly these characteristics. PABRA's work doesn't stop there, however: the organisation distributes and promotes these seeds, holds workshops, coordinates between partners and provides support to small business owners. The impact of PABRA and its partner organisations can be felt all along the bean corridor.

To understand how PABRA makes a difference, we have detailed the journey of one bean as it travels the bean corridor. This is the story of Yakina the bean.

Yakina the bean

Yakina is a climbing variety of bean scientifically known as MAC44. The speckled red legume grows in the hills surrounding Mount Heha in the western part of Burundi, a small central African country and one of the world's poorest states. Over the past eight weeks, Yakina has been growing here in the fields of a female smallholder farmer who works around one-fifth of a hectare of land. She wanted to try out one of the new varieties of beans that she learned about in a PABRA workshop. She also received training on sowing, tending to and cultivating the beans. In her first year of growing these, she was able to nearly double her yield compared to conventional varieties.

No more hunger and malnutrition

The farmer and her family now have enough to eat – something that can't be taken for granted in Burundi. Their health has also improved thanks to the properties of this type of bean: these beans have been biofortified to contain significantly higher amounts of iron and zinc, bringing years of malnutrition to an end. The family even has a little bit of money left over after the harvest, enabling them to buy a few eggs every now and then.

It's now harvest time. Yakina is hanging off its stalk, enjoying the sun. The farmer and her family are busy with the harvest. The soil quality of her smallholding has improved since planting the beans, which in turn has boosted the quality of her vegetable crops. This is because beans return nitrogen to the soil instead of depleting it. 

After the harvest, Yakina is dried along with the other beans and filled into sacks. The beans used to get attacked during storage by pests like the bean beetle, which led to panic selling or the destruction of entire harvests. For this reason, PABRA introduced the farmers to PICS bags, which can be hermetically sealed. Local companies have taken over production and sale of the bags, and PABRA was also able to convince the Burundian government to subsidise them. This has made the bags both accessible and affordable to people living in remote areas.

Success empowers women

The farmer keeps a part of the harvest to feed herself and her family. Ever since she visited a nutrition workshop organised by PABRA, she has been able to serve more meals with more variety. She is noticeably proud of the fruits of her labour and the knowledge she has acquired. Armed with a new sense of self-confidence, she even starts taking a more active part in discussions about the future of her community. She even does so when men are present, which is not the norm in her country.

In Burundi's patriarchal society, women are responsible for putting food on the table while men take care of earning money. The farmer's husband has used his mobile phone to register on a bean platform in order to sell his wife's beans. Thanks to this platform, which was organised by PABRA, he is able to reach more buyers and therefore receives a better price.

Business flourishes along the value chain

A company in Bujumbura, the country's capital, wins a bid to buy the beans. It is a prospering flour company founded and run by a woman. What started as a one-woman business in her backyard now occupies its own building and has 17 permanent employees. The company mills corn, soy, and most importantly, biofortified beans. Yakina and other beans are loaded into a new, larger-capacity grinding machine that the company was able to finance thanks to PABRA-coordinated funds from Switzerland.

Yakina the bean is now milled into flour, which is purchased by the kilo and brought to a nearby childcare centre. The women working at the childcare centre have also attended PABRA's nutrition workshops and turn the bean flour into a tasty porridge. The children eagerly wolf it down, evidently also enjoying the flavour.

As the spoonfuls of porridge are scooped up, Yakina the bean arrives at the final destination of its journey.

About PABRA – Pan-Africa Bean Research Alliance

PABRA is an international network of scientists, smallholder farmers, private companies, governments, policymakers and civil society organisations working in 32 countries throughout sub-Saharan Africa. PABRA is coordinated by the International Center for Tropical Agriculture (CIAT), a research centre of the Consultative Group for International Agricultural Research (CGIAR). PABRA's main mission is improving the living conditions of smallholder bean farmers, many of whom are women. This is made possible via efficient networks, solid research and improved seed systems. PABRA has reached over 38 million farming households and 200 private companies in the bean sector throughout Africa to date.

One of the SDC's longest-lasting programmes

The Swiss Agency for Development and Cooperation (SDC) has been a supporter of PABRA and its predecessor organisation since 1983, making it one of the SDC's longest-lasting programmes. And with good reason: PABRA produces tangible results (see infographic) and shares the objectives of Switzerland's Foreign Policy Strategy 2020–23. The organisation creates local jobs, offers responses to climate change and addresses the push factors driving migration.

Cooperation with government authorities such as the Burundi Institute of Agronomic Sciences (ISABU) has helped PABRA reach over 1.2 million smallholder farmers in the country, who are now able to work with improved varieties of beans. This translates into 4.5 million smallholder families with significantly improved levels of nutrition and more empowered mothers and daughters.

However, many challenges remain, with climate change and population pressure among the most critical. There is still much to do.

PABRA will stay the course – with Swiss development cooperation offering its continued support.
