Many sustainability assessment frameworks have been developed in recent years, but translating them into practical tools to guide decision making remains challenging. By engaging coffee stakeholders in Uganda, we demonstrate a process of translating the widely-accepted framework for Sustainabilit...

Recent and current efforts at IITA to assess risks due to the various biotic stresses, arthropod pests and diseases, are presented for different cropping systems. In the case of cassava arthropod pests, the focus is on temperature-mediated interactions between the pest and its natural enemy which...

A survey was carried out in 108 fields in Rwanda to identify constraints to banana productivity in three regions: Ruhengeri (young volcanic soils), Gitarama–Butare (soils derived from granitic rocks), and Kibungo (weathered soils from schistose materials). Data were recorded for the single cultiv...

East African highland cooking banana (Musa spp., ‘Matooke’, AAA-EA genome) prices are sensitive to supply dynamics given their perishable nature. Despite large temporal fluctuations in farm-gate prices and food security, no efforts have been made to shift banana production towards periods of high...
Mulch applications generally have a large beneficial effect on the productivity of important perennial cash crops in the East African Highlands such as bananas (Musa spp.) and coffee (Coffea spp.), due to the conservation of soil moisture and the improvement of soil fertility. However, the availa...

Banana is the primary food crop in Uganda, but yields are low due to a complex of abiotic and biotic constraints. However, quantitative information on the importance, interactions, and geographic distribution of yields and constraints is scanty. We monitored yields, biotic and abiotic constraints...

Coffee and banana are major cash and food crops, respectively, for many smallholders in the East African highlands. Uganda is the largest banana producer and 2nd largest coffee producer in Africa. Both crops are predominantly grown as monocultures. However, coffee–banana intercropping is common i...
