Goals and Approach

Integrated Multi-scale, Multi-sector Modeling​ The long-term goals of the IM3 project are to:

  1. Develop a flexible and extensible modeling framework that captures the dynamic multi-scale interactions among energy, water, land, climate, socioeconomics, critical infrastructure, and other sectors.
  2. Use this framework to study the vulnerability and resilience of coupled human and natural systems from local to continental scales under scenarios that include short-term shocks, long-term stresses, and feedbacks associated with human decision making.
  3. Explore how different model configurations, levels of complexity, multi-model coupling strategies, and spatial and temporal resolutions influence simulation fidelity and the propagation of uncertainties.

Our approach emphasizes leveraging related activities and emerging capabilities, systematically increasing complexity, and engaging with a range of communities to help establish this project as a long-term home for cutting-edge impact, adaptation, and vulnerability research.

The first three years of IM3 will focus on building the foundational scientific understanding and computational tools needed to develop and deploy an integrated multi-sector, multi-scale modeling framework, with major research thrust areas in population dynamics, land use and land cover change, and the energy-water nexus.

Ultimately, our vision is to dramatically improve scientific understanding of how the complex coupled human-Earth system responds to different stresses, which will in turn inform decision-making across a range of sectors and scales.
