Recent decades of formal crop improvementBreeding plants that can take advantage of fertilizer, irrigation and mechanization Focus on yield, uniformity in a few crops

Increasing privatization & centralization Molecular technologiesLots of other technical innovations

Broader range of cropsParticipatory approaches and other methods innovations

CCRP principles how do they apply to crop improvement projects?

CCRP niche 1: Whom do we serve?Moremarket accessLessmarket accessHigh resource endowmentLow resource endowmentEquityFood security and poverty reductionEnvironmental and social sustainability CCRP niche 2: What crops?International marketsSelf-provisioningCash crop value chainsDiverse local cropsLocal marketsMixedCultural valueNutritional outcomes CCRP niche 3: AEI through CoPGlobalLocalSystemsComponentsPest-resistant germplasm of crop X: genetics and pre-breedingParticipatory selection of desirable and pest-resistant varieties of crop X in location YManaging pest and other risk in location Y
