This is combined with understanding the overall system and issues which relate to this. When this is done, there is an understanding of key issues within the assessment and the necessity to create different responses with the case study and the understanding of principles that are created.The main categories that are related to sustainable development principles relate directly to the understanding and links of how these can be used in a different context. The approach is to create an economic, social, and environmental sense of quality within the different needs that are a part of the development. This is combined with the idea of creating a holistic approach, specifically which is inclusive of developing different roles for various needs with the principles which are used. To further sustainability, some elements are required, including economic development, environmental quality, and social equity that occurs. The adequate scope furthers this with the understanding of time scales and how this can work with the long – term goals that are created. The activities, amount of communication, practical roles, participation, efficiency, and the ability to change different roles also furthers this. Monitoring, evaluation, and change of the different expectations with the operations then allow for the categories and principles to be associated with the development of the quality required.While the basis of sustainable development is available, there is not an understanding of how this will affect future generations. This is one of the main gaps that is associated with analyzing and responding to environmental, social, and economic developments. One can base the sustainable development principles on current trends and expectations. However, this may hurt others within the community and may not be used for effective expectations.
