The countries pilot testing national indicators of sustainable development in support of the UNCSD programme on indicators find they need at least 50 indicators to cover the major dimensions of sustainability (Government of the Czech Republic 1998). The UNCSD study calls for economic, social, environmental and institutional indicators covering driving forces, states and responses across all the programme areas of Agenda 21, with 134 indicators identified in the first phase. These activities have made clear how many dimensions there are to development. They also highlight the need to develop clearer targets and goals, and new indicators for the less tangible aspects of development including individual welfare, community cohesion, institutional development, knowledge and culture.
