The transformation process is necessarily long term. With governments elected for five years, there is an inherent tendency to postpone addressing long-term development issues that is all the more difficult in the context of a highly partisan political tradition that resists consensus over development strategies. Progress in mainstreaming the environmental dimension of sustainable development strategies has been slow. Such policies address cross-cutting issues, and in the Westminster system of sectoral portfolio ministerial responsibilities, such issues tend to fall between ministerial responsibilities.
