Davoudi (2010) explored the various approaches to sustainable development as understood together with the efficacy and value of the various issues that connect between development issues and the need to safeguard the environment. Some of the approaches explored include ecological modernization, risk society, and traditional approaches. In this regard, it makes sense to consider these matters in terms of the concerns raised about the preservation of the environment. Campell (1996) examined the key details that engage the minds of planners in their quest to achieve green cities. The triangular model used in the understanding of these challenges provides a broad insight into the weaknesses of past and current approaches in light of the desire to achieve comprehensive development. Among the dominant issues discussed is the matter of priority with particular attention to urban development versus environmental concerns at hand.
The study by Cowell and Owens (2006) did not provide sufficient emphasis on the technical areas of cooperation in view of the competing perspectives on the same. Furthermore, the study did not provide enough specifics regarding the challenges faced by policy implementers in order to justify the kind of approaches adopted for remedy. In his comparison of the various approaches of sustainable development, Davoudi (2010) did not provide insights into the possible ways that could enhance the efficiency of some of the innovative approaches of sustainable development. The approach suggested by Campbell does not seem to engage with the matter of the most viable solutions because much emphasis is placed on the comparison between past and current approaches to sustainable development.
Ultimately, the dominant factor in this study revolves around the need to establish a workable approach that could be relied upon to develop a comprehensive approach to the matter of sustainable development. Conservation entails multiple approaches that must take care of economic development, environmental conservation, and human development. As such, the issues brought forth in this argument provide a comprehensive review of the matter of environmental conservation and planning. In some way, the approaches seem to acknowledge the dynamic issues that connect with sustainable development within a broad context.
The key issues involved in the discussion revolved around the need to invent an all-inclusive approach that would entail the harnessing of the various synergies towards a united pattern of development. As such, the various approaches adopted by the authors have important strengths that could help in the designing of such a master plan.
