Knowledge reviews
What is it: Knowledge Review are relatively short documents collecting and
synthesizing knowledge on complex topics. They are rigorous, but not too
technical. They focus on key messages from science and policy
recommendations
Who needs it: Knowledge Reviews are primarily targeting policy-makers but
are also useful for researchers, the private sector, NGO, civil servants
How they are done: It is as much as possible a neutral exercise in which it is
reported what is found in the literature, including recommendations, knowledge
gaps and different views.

Knowledge Review on NUS - Background and context
Prepared by the secretariat of the
Knowledge Centre for Global Food and
Nutrition Security with contribution from
IRAM (Institut de recherche et d'applications
des méthodes de développement)
Elaborated upon request by the 2
Directorates General of the European
Commission: INTPA (International
Partnerships) and ECHO (Humanitarian
assistance)

Neglected and underutilised species (NUS)
• Policy needs and context
• DG INTPA is interested in promoting the use of NUS as a complement to
mainstream crops (wheat, rice, maize) in third countries, particularly in Africa, as
part as the transition towards more sustainable and resilient food systems
• DG ECHO in interested in the contribution of locally-produced crops, including
neglected and underutilised ones, in emergency contexts, e.g. for the preparation of
emergency food (Ready to Use Therapeutic Food) to distribute
• Main questions: Can NUS contribute to food and nutrition security, small
famers’ income, environmentally sustainable agriculture and resilience? Can
they be used in emergency context? What are enabling factors and
obstacles? Are there other benefits or limitation associated to the use of
NUS?

Neglected and underutilised species (NUS)
Key findings – NUS benefits
• Food security NUS can contribute to food security by increasing food availability during the
lean period, improving production under harsh conditions and on marginal soils, where
mainstream crops often fails;
• Income: NUS can enable communities to engage in diversified income-generating activities;
• Nutrition and health: Many NUS are rich in essential macro and micronutrients. Several NUS
have also antioxidants and anti-inflammatory properties.
• Sustainability and Resilience: Many NUS exhibit higher tolerance to stresses such as
drought, pests, and diseases compared to mainstream crops. Several NUS can thrive in poor
soil conditions and require less inputs.
• Gender equality: There’s a correlation between NUS production and women’s empowerment,
as women are the main custodians and producers of NUS
• Emergency situations NUS can be used as alternative ingredients for locally-produced, cost-
effective Ready-to-use therapeutic and supplement foods (RUTF-RUSF). Additional research
is needed on this, though

Neglected and underutilised species (NUS)
• Key findings – Obstacles
• Market access: NUS are often sold by smallholder farmers in informal markets, which
limits their availability to consumers
• The high market value of certain NUS offers an opportunity to generate income, but
this is hindered by the underdevelopment of value chains and processing methods
• Seed accessibility is an issue. Conservation systems are needed to make seeds and
knowledge available and to scale up NUS’s uptake
• Though a great body of evidence is available, information on NUS’s benefits it’s still
scattered. Knowledge gaps persist on NUS’s agronomic and nutritional traits. There is
consensus that more research is needed on the topic
9
Main Policy recommendations
• Invest in seed conservation systems, both in situ (on farm) and ex-situ, in seed
conservation banks
• Develop value chains for NUS by informing consumers on their benefits, promote
them in policies through adequate incentives/subsidies (currently mainly favouring
mainstream crops)
• Schools' meals and public procurements are important ways for promoting NUS
• Promote investments in capacity building, training, teaching, research improved
storage and packaging, improved transportation, targeted investments in rural
infrastructure and investing in processes with added value.

Some actions of the European Commission
supporting NUS
- The DESIRA+ project, financed by the EU with €100 million + EU Member States
contributions. It aims at strengthening agriculture research and innovation to
support agroecological transition of food systems in Sub-Saharan Africa, and NUS
are one of the specific covered topics (LINK)
- The upcoming AgrEcoNUS + project, aimed to enhance value chains and markets
of NUS to contribute to Agroecological transition in Africa (LINK) (Contracting
entities: AICS (Italian cooperation Agency) and IFAD.
Starting in February 2026 – duration: 4 years
3 main areas: 1) Research and Innovation; 2) Policy and Governance and 3) Value
chains and markets
- Research: the Horizon Europe programme finances several (past and
ongoing) research projects on that include NUS, e.g.: RADIANT;
CROPDIVA Bio-Value. Upcoming project on the use of local crops for
RUTF/RUSF
