Challenges in Sustainability

This manuscript presents an analysis of commercially developed appraisal instruments (CDAIs) using composite indices to assess, compare and rank the sustainability performance of cities and communities. A group of CDAIs using composite indices are commonly used to assess, compare, and rank the sustainability performance of cities and communities. As a sustainability assessment methodology, composite indices gather qualitative and quantitative information which is then used to calculate the overall performance of the principle (e.g., sustainability); the stand-alone number, commonly known as an index, is often used to compare and rank performance. Because of practicality and mistakenly perceived simplicity, the assessment methodology is often misunderstood and underestimated. Issues, skepticism, and criticism surrounding composite indices are rooted in the lack of structured and transparent methodological frameworks for the identification and selection of elements within each hierarchical level. Although scientifically-based methodologies and processes have been developed to assign relevance (i.e., weighting) and aggregate performance to calculate the stand-alone index, the effectiveness of the assessment methodology (i.e., composite indices) is still influenced by various degrees and types of subjectivity and uncertainty. To evaluate their effectiveness, the manuscript discusses three characteristics of CDAIs using composite indices: (1) the hierarchical structural organization (HSO) considers the aim of each hierarchical level in the assessment process, (2) the identification, selection and design of the elements (e.g., principle, sub-principles, criteria, indicators) included in each hierarchical level as a determinant factor in capturing the various facets of the sustainable development notion, and (3) the quantification methodology (i.e., weighting and aggregation system [W&AS]) implemented by the developer or proponent of the assessment tool. The analysis of CDAIs using composite indices effectiveness is partially assisted by three frameworks designed by consensus (FDC): (1) ISO 37130:2018 Sustainable development of communities—Indicators for city services and quality of life which is complemented with ISO 37122:2019 Sustainable cities and communities—Indicators for smart cities and ISO 37123:2019 Sustainable cities and communities—Indicators for resilient cities, (2) United Nations Sustainable Development Goals (UN SDGs) with emphasis on Goal 11, and (3) customized frameworks for sustainable cities (CFSS) with a focus on sustainability plans designed and implemented by the cities of Vancouver and Montreal which are used as case studies. While the findings support the applicability and usefulness of CDAIs using composite indices as assessment methodology, the appropriateness of comparing and ranking the sustainability performance of cities and communities is an unsettled debate with several areas for improvement and future research.

Capturing the various facets of sustainable development is the main objective of sustainability assess- ment studies. Scientists and practitioners use sustainable development criteria and indicators as instruments to link the theoretical definitions with the evaluation of the effectiveness of management strategies; therefore, identifying and selecting indicators are the most critical processes in evaluating the implementation of sustainable development strategies and progress toward achieving sustainability goals and objectives. The manuscript argues the need for increasing credibility in the identification and selection of criteria and indicators through stakeholder engagement, participation and management. Sustainability aims to primarily address and balance the [social, economic, environmental] needs and expectations of stakeholders; therefore, reaching consensus amongst the various groups of stakeholders became the determining factor in the design, implementation, and assessment of sustainable development strategies. Because a precise definition of sustainability that is universally agreed upon is yet to be introduced, the process of identifying and selecting indicators to assess progress toward achieving sustainable development is embedded in subjectivity and vagueness and can be easily manipulated to meet particular interests. Furthermore, the absence of rigorous and standardized methodological frameworks contributes to continuously proposing set indicators that best capture the notion of sustainable development which creates distrust in the assessment process and directly affects the credibility of the sustainability concept. Departing from acknowledging the relevance of stakeholders groups in decision-making and management processes, the manuscript identifies and discusses three credible and reliable frameworks designed by consensus (FDC) to identify and select criteria and indicators to assess the sustainability performance of cities and communities: (1) ISO 37130:2018 which is complemented by ISO 37122:2019, (2) United Nations Sustainable Development Goals (UN SDGs) with focus on Goal 11, and (3) customized frameworks for sustainable cities (CFSS). To minimize subjectivity and strengthen credibility, the manuscript also makes the case for the need of embedding FDC into sustainability assessment processes to identify and select criteria and indicators. Because of the methodology adopted for their development, FDC provide scientists and practitioners with reliable and credible sources to identify and select criteria and indicators for the assessment of the sustainability performance of cities and communities.

The Bayano region, in Panama, has been linked to many different stakeholders who were or are influenced by the Bayano dam, which was completed in 1976 and flooded a large area. Stakeholder Tables are a good way of exploring the views of stakeholders and their relationships. They can also help in identifying Hidden Stakeholders. Hidden Stakeholders refer to stakeholders who use or are impacted by regions or events, but are generally ignored. In this study, several sources, including discussions with community members and workshop results, were used to develop a Stakeholder Table for the Bayano region. Stakeholders include displaced Guna and Embera indigenous communities. In order to identify Hidden Stakeholders, the table was applied to relevant court cases and agreements, with Hidden Stakeholders being those who were not addressed in these documents. Hidden Stakeholders include indigenous individuals who raise cattle or are involved in tree felling, along with tourism industries. Using some follow-up workshops to collect potential interventions, a Relational Values approach was used to find sustainable projects and methods that can target multiple Hidden Stakeholders at the same time.
