A wide range of African vegetable varieties are threatened with extinction, while others have already disappeared as climate change, urbanisation and poor eating habits take their toll.
Speaking at the Africa Food Systems Forum (AFSF) in Kigali this week, experts said many indigenous African vegetable species are already extinct and others will soon disappear if nothing is done.
“The most endangered species are the indigenous African vegetables, due to many historical events, many of the indigenous vegetable varieties have been replaced by exotic breeds, and the challenge now is where to find these materials,” said Dr Sognigbe N’Danikou, a scientist and expert on the conservation and use of traditional vegetables at the World Vegetable Centre, a non-profit involved in vegetable research.
He said, for instance, that a certain type of okra (Abelmoschus manihot), which was widely consumed in West Africa and traditionally used for medicine, is now very difficult to find.
Others, like black night shade and amaranth, are critically endangered, while a host of other edible wild weeds that were eaten in the past have disappeared. Most of these herbs are rich in minerals and vitamins that are vital to local diets.
In the last 100 years, up to 75 percent of the global diversity of African vegetables has been lost, he argued.
A global problem
But the problem is global. The National Geographic recently reported that that between 1903 and 1983, seed varieties shrank by about 93 percent, and 30 years later, the fruits and vegetables from those seeds diminished even more drastically.
For instance, 544 varieties of cabbage shrank to just 28, while 463 kinds of radishes were reduced to 27.
In Africa, urbanisation, climate change and poor farming methods have been some of the biggest threats.
When bushes are cleared to construct roads and expand cities, many vegetable varieties are destroyed never to be seen again, as many of their seeds are not even preserved.
In eSwatini, one of the countries with the highest rate of vegetable extinction, the indiscriminate use of herbicides has been a major cause of species destruction.
Meanwhile floods, landslides and other natural disasters, that come as a result of climate change, have led to the disappearance of some vegetable varieties.
Yet governments and private sector have not done enough to invest in sufficient seed banks and research to protect these vegetables.
Rescue project
At the AFS Forum, the World Vegetable Centre launched the Vegetable Biodiversity Rescue Plan, which will act as a roadmap to address the threats stalking the vegetable species in order to reverse their disappearance.
“The knowledge around these species has also been lost in many traditional communities.
“Africa is also home to many vegetable species whose wild relatives are endangered and disappearing, largely due to urbanisation and climate change. For example, the wild relatives of cowpeas, which is originally domesticated in Africa have disappeared,” said Mr Sognigbe.
He noted that the rescue project will, among other things, seek to collect seeds of these wild varieties and conserve them so that they can be bred in the future.

Up to $12.5 million is required to implement the 10-year rescue plan, and a pilot was carried out with support of the Taiwan Africa Vegetable Initiative from 2021 to 2024, to conserve and use African vegetable biodiversity to address malnutrition.
As part of the pilot project, over 17,000 vegetable varieties have been collected in Benin, Eswatini, Madagascar and Tanzania for preservation.
So far, achievements made through the pilot phase include two newly constructed and three upgraded African genebanks, in addition to training some 174 African genebank staff.
“This is a matter of urgency. Policy makers, scientists and other stakeholders need to join hands in rescuing these endangered vegetable varieties. We are glad private sector entities like Equity Bank has come on board to support these efforts,” said Colleta Ndunguru, the World Vegetable Centre programme manager for Tanzania.
“We need to make room to promote and support farmer-managed seed systems.”
Experts say there is a need to invest in conservation infrastructure at the national level to ensure there are functioning gene banks that can preserve and replicate what farmers have, so that varieties can be preserved before they are lost.
“We need to promote inclusion of these vegetables in our diets by adopting policies that facilitate and encourage farmers to grow these materials and also consumers to integrate these in their diets,” she said.

Air Tanzania Banned From EU Airspace Due to Safety Concerns
Several airports have since locked Air Tanzania, dealing a severe blow to the Tanzanian national carrier that must now work overtime to regain its certification or go the wet lease way
The European Commission has announced the inclusion of Air Tanzania on the EU Air Safety List, effectively banning the airline from operating in European airspace.
The decision, made public on December 16, 2024, is based on safety concerns identified by the European Union Aviation Safety Agency (EASA), which also led to the denial of Air Tanzania’s application for a Third Country Operator (TCO) authorisation.
The Commission did not go into the specifics of the safety infringement but industry experts suggest it is possible that the airline could have flown its Airbus A220 well past its scheduled major checks, thus violating the airworthiness directives.
“The decision to include Air Tanzania in the EU Air Safety List underscores our unwavering commitment to ensuring the highest safety standards for passengers in Europe and worldwide,” said Apostolos Tzitzikostas, EU Commissioner for Sustainable Transport and Tourism.
“We strongly urge Air Tanzania to take swift and decisive action to address these safety issues. I have offered the Commission’s assistance to the Tanzanian authorities in enhancing Air Tanzania’s safety performance and achieving full compliance with international aviation standards.”
Air Tanzania has a mixed fleet of modern aircraft types including Boeing 787s, 737 Max jets, and Airbus A220s.
It has been flying the B787 Dreamliner to European destinations like Frankfurt in Germany and Athens in Greece and was looking to add London to its growing list with the A220.
But the ban not only scuppers the London dream but also has seen immediate ripple effect, with several airports – including regional like Kigali and continental – locking out Air Tanzania.
Tanzania operates KLM alongside the national carrier.
The European Commission said Air Tanzania may be permitted to exercise traffic rights by using wet-leased aircraft of an air carrier which is not subject to an operating ban, provided that the relevant safety standards are complied with.
A wet lease is where an airline pays to use an aircraft with a crew, fuel, and insurance all provided by the leasing company at a fee.
Two more to the list
The EU Air Safety List, maintained to ensure passenger safety, is updated periodically based on recommendations from the EU Air Safety Committee.
The latest revision, which followed a meeting of aviation safety experts in Brussels from November 19 to 21, 2024, now includes 129 airlines.
Of these, 100 are certified in 15 states where aviation oversight is deemed insufficient, and 29 are individual airlines with significant safety deficiencies.
Alongside Air Tanzania, other banned carriers include Air Zimbabwe (Zimbabwe), Avior Airlines (Venezuela), and Iran Aseman Airlines (Iran).
Commenting on the broader implications of the list, Tzitzikostas stated, “Our priority remains the safety of every traveler who relies on air transport. We urge all affected airlines to take these bans seriously and work collaboratively with international bodies to resolve the identified issues.”
In a positive development, Pakistan International Airlines (PIA) has been cleared to resume operations in the EU following a four-year suspension. The ban, which began in 2020, was lifted after substantial improvements in safety performance and oversight by PIA and the Pakistan Civil Aviation Authority (PCAA).
“Since the TCO Authorisation was suspended, PIA and PCAA have made remarkable progress in enhancing safety standards,” noted Tzitzikostas. “This demonstrates that safety issues can be resolved through determination and cooperation.”
Another Pakistani airline, Airblue Limited, has also received EASA’s TCO authorisation.
Decisions to include or exclude airlines from the EU Air Safety List are based on rigorous evaluations of international safety standards, particularly those established by the International Civil Aviation Organization (ICAO).

The process involves thorough review and consultation among EU Member State aviation safety experts, with oversight from the European Commission and support from EASA.
“Where an airline currently on the list believes it complies with the required safety standards, it can request a reassessment,” explained Tzitzikostas. “Our goal is not to penalize but to ensure safety compliance globally.”
Airlines listed on the EU Air Safety List face significant challenges to their international operations, as the bans highlight shortcomings in safety oversight by their home regulatory authorities.
For Air Tanzania, this inclusion signals an urgent need for reform within Tanzania’s aviation sector to address these deficiencies and align with global standards.
The path forward will require immediate and sustained efforts to rectify safety concerns and regain access to one of the world’s most critical aviation markets.
