Abstract
WARDA was restructured and became a CGIAR center in 1986. Research is organized by ecosystems, including the upland-inland valley swamp continuum, the Sahel irrigated rice ecosystem, and the mangrove rice ecosystem programs. This paper discusses the institutional and collaborative requirements for systems research in West Africa. It also proposes a symmetry in complexity and integration between researched system and research system. An open-center concept was developed at WARDA as a means to achieve a critical mass of scientists and to encourage a more interdisciplinary and interinstitutional integration for systems research. Examples of the concept are the task-force system that integrates the effects of NARS and WARDA, the consortium program that focuses on inland valleys in the humid zone, and the Sahel diagnostic network that emphasizes crop-climate interactions in the arid zone. A need to intensify training programs to achieve full NARS-IARC partnership in systems research has been identified. WARDA’s systems research on Sahel irrigated rice is presented in more detail, with an emphasis on cropping calendar x genotype x climate interactions. The regional variations in crop calendars was analyzed and explained using simulation methods. Improvements are now sought through breeding and organizational studies at the level of the village or irrigation scheme.
