The Green Challenge is an up-to-date and comprehensive account of the development of Green parties in Western Europe, and includes an account of the development since 1989 of an East European Green movement.Blending theory and empirical analysis, the book contains chapters on each of the main western European cases and on a number of other less-studied ones. These are designed to demonstrate the shifting balance of party-political competition the factor the authors believe most strongly influences the fortunes of the Greens.The editors also integrate a valuable analysis of the environmentally-degraded Czech Republic, where the Green parties' lack of electoral success has puzzled many observers.
