It is recognized internationally that planning for sustainability requires an understanding of how economic, social, and environmental factors interact with and affect each other.   Some years ago, computerized planning tools to meet this need did not seem possible. Such tools have now been created and field-tested with success.  

Customized integrated planning tools are powerful for gaining insight into the dynamics of complex systems and stubborn, widespread challenges such as economic self-determination for the poor.  These tools allow specialists in any area to understand how proposed policies in one area of national development would affect the whole system. For example, Gross Domestic Product is often chosen as a key indicator of economic growth. However, social and environmental indicators such as literacy, health, and clean air and water are also important indicators that influence a country’s ability to attain sustainable economic growth. Integrated tools allow planners to see how these indicators influence each other and the whole system.  Working collaboratively, they can make the best decisions on combinations and sequencing of policies to attain stated goals and maintain the progress over time.

MI’s planning tools support integrated analysis such as is required for addressing complex national development issues, and are useful for preparing poverty reduction strategies and plans to meet the Millennium Development Goals. MI’s integrated planning tools are:

Threshold 21

Threshold 21 (T21) is a national model designed to support comprehensive, integrated planning, and is a valuable quantitative tool for testing policy, monitoring, and evaluating results.  Based on country-driven goals, T21 allows users to generate scenarios indicating the future consequences of the proposed strategies.  Users can then trace changes in outcomes back to the assumptions and polices that produced those changes. This capability helps users identify vital leverage points and key assumptions.

Threshold 21 Integrated Sustainable Development Model

The iSDG model simulates the fundamental trends for SDGs until 2030 under a business-as-usual scenario, and supports the analysis of relevant alternative scenarios. The model also traces the trends beyond the SDGs’ time span to 2050. The model is structured to allow for a rapid expansion to support the analysis of country-specific issues beyond the SDGs.
