We have helped more than 40 nations and multilateral institutions identify strategies that offer all people access to food, water, health care, education, and equal opportunities for women and men.

Modeling & Research


We develop integrated System Dynamics models to analyze sustainability issues, including ecological agriculture and food security, green economy, conservation, health, population dynamics, and more.


Threshold 21 (T21) is a policy simulation tool for comprehensive, integrated long-term national development planning.  WithT21 users can compare analysis of different policy options, and to identify policy sets that lead towards a desired goal.  T21 modeling deepens users’ understanding of development challenges by showing how different aspects of development interact with one another to produce outcomes.
T21 has developed from more than 20 years of research and application carried out in consultation with the World Bank, UN agencies, developing country governments, and non-governmental organizations. T21 has been applied in more than 30 countries over the past twenty years, and is consistently ranked at the top of integrated policy planning models in independent reviews.


Integrated Sustainable Development Goals (iSDG) model is a policy simulation tool designed to help policy makers and planners make sense of the complex web of interconnections between the 17 SDGs. Unlike static indicators, databases and indexes that provide a measure of where a country stands, iSDG focuses on the dynamic interactions within the SDG system to reveal the best paths and progression towards achieving the SDGs.
