Basic Framework

Sustainomics seeks to provide a comprehensive, practical framework for making present and future development efforts more sustainable. Sustainable development has become well accepted worldwide, following the 1992 Earth Summit in Rio de Janeiro, and the 2002 World Summit on Sustainable Development (WSSD) in Johannesburg. World decision makers are now looking at this approach to address many critical policy issues.

The World Commission on Environment and Development (WCED 1987) defined sustainable development as “development which meets the needs of the present, without compromising the ability of future generations to meet their own needs.” Among many subsequent definitions, the sustainable development triangle in Figure 1 shows one widely-accepted concept proposed by Munasinghe, at the 1992 Earth Summit in Rio. It encompasses three major perspectives—economic, social, and environmental.

Historically, the development of the industrialized world focused on material production. Not surprisingly, most industrialized and developing nations have pursued the economic goal of increasing output and growth during the twentieth century. Thus, traditional development was strongly associated with economic growth, with some social aspects as well (see the discussion on poverty and equity, below). By the early 1960s the lack of ‘trickle-down’ benefits to the growing numbers of poor in developing countries, resulted in greater efforts to improve income distribution directly. Consequently, the development paradigm shifted towards equitable growth, where social (distributional) objectives, especially poverty alleviation, were recognized to be as important as economic efficiency. By the early 1980s, a large body of evidence had accumulated that environmental degradation was a major barrier to development, and new proactive safeguards were introduced (such as the environmental assessments). Thus, protection of the environment became the third major element of sustainable development.

Sustainomics has been described by Munasinghe as “a transdisciplinary, integrative, comprehensive, balanced, heuristic and practical framework for making development more sustainable”. It draws on the following basic principles and methods.

Making development more sustainable (MDMS)

The step-by-step approach of “making development more sustainable” (MDMS) becomes the prime objective, while sustainable development is defined as a process (rather than an end point). Since the precise definition of sustainable development remains an elusive and perhaps unreachable goal, a less ambitious strategy that merely seeks to make development more sustainable does offer greater promise. Such a gradient-based method is more practical and permits us to address urgent priorities without delay, because many unsustainable activities are easier to recognize and eliminate. Although MDMS is incremental, it does not imply any limitation in scope (e.g., restricted time horizon or geographic area – see item (c) below). While pursuing the MDMS approach, we also follow a parallel track by continuing our efforts to better define the ultimate goal of sustainable development. Finally, MDMS encourages us to keep future options open and seek robust strategies which meet multiple contingencies and increase resilience.

Sustainable development triangle and balanced viewpoint

Sustainable development requires balanced and integrated analysis from three main perspectives: social, economic and environmental (Figure 1). Each viewpoint (represented by a vertex) corresponds to a domain (and system) that has its own distinct driving forces and objectives. The economic view is geared towards improving human welfare, primarily through increases in the consumption of goods and services. The environmental domain focuses on protection of the integrity and resilience of ecological systems. The social domain emphasizes the enrichment of human relationships and achievement of individual and group aspirations. The interactions among domains (represented by the sides) are also important to ensure balanced assessment of trade-offs and synergies that might exist among the three dimensions. Issues like poverty may be placed in the center of the triangle to re-emphasize that they are linked to all three dimensions.
