Getting to know NUS

Neglected and unterutilized species (NUS) are plants with excellent nutritional properties, but which have somehow been abandoned due to a lack of market demand or a lack of deeper understanding of their nutritious properties, health benefits and valuable use in local dishes.

NUS in the CROPS4HD project

NUS in the CROPS4HD project

Through the project Consumption of Resilient Orphan Crops and Products for Healthier Diets (CRPS4HD), SWISSAID encourages the cultivation of essential, yet often underutilized, nutrient-rich crops.

The project focuses on improving seed conservation through seed banks, increasing access to local seeds, and supporting small-scale farmers in producing these crops. This approach aims to enhance food security, nutrition, income, and environmental sustainability.

Bambara beans

More information

Bambara beans are an important drought-resistant pulse crop in Africa, serving as a valuable alternative to other nuts and pulses, especially in regions with limited water resources.
