Sustainability indicators: the problem of integration

Sustainability indicators (SIs) are increasingly seen as important tools in the implementation of sustainable development. Numerous suggested SI lists and matrices exist, but a remaining problem is how these diverse SIs are to be integrated into an answer as to whether something is sustainable or not. In some studies of sustainability workers have adopted a quantitative integration approach whereby SIs are given numerical values and integrated mathematically to produce a value for sustainability. In this paper the authors discuss SI integration by drawing upon the results of a six-year research project based in a village in Nigeria. They conclude that an element of'qualitative integration' incorporating value judgements and subjectivity is inevitable with a concept such as sustainability, even if one begins with what may seem like sharp and quantitative SIs. It is argued that SIs are primarily a product of development intervention rather than a desire to understand, and as a result carry with them the desired characteristics, from the donor perspective, of efficiency and accountability.
