Project 3: Enhancing the Performance of Irrigated Rice-based Systems in Africa

Irrigated-rice systems realize high yields per days of water provided pesticides are used rationally and the range of degradation processes such as salinity, alkalinity and iron toxicity are corrected. Presently, the narrow genetic base of existing improved varieties limits the germplasm for this ecology. This project adopts a holistic approach embracing not only germplasm improvement and efficient crop and natural resource management techniques, but also the changes in policy that are needed to support a profitable future for irrigated production. Working with NARES and with small- and medium-scale farmers will ensure that improved research results are rapidly transferred. The project focuses on: (i) germplasm improvement for yield and stresses; (ii) halting environmental degradation at the farm level; (iii) developing systems to make efficient and sustainable use of inputs, including post-harvest, while maximizing the returns; (iv) intensification and diversification opportunities, including rice-livestock and rice-vegetable integration. In this project the biodiversity and genetic improvement aspects linked to SP1 and 2 are addressed, as well as SP4 and the policy dimensions in 5d.
