Complex Adaptive Modelling of the Health Impacts of Climate Change in Malawi

Project

Last Updated on July 4, 2024

Project Description

Malawi is among the countries most affected by climate change, and its Chilwa Basin is one of the most severely affected regions in the country.

Extreme weather events, flood, drought, changing rain patterns, prolonged high temperatures, and human-induced deforestation have major impacts on human health and lead to population displacement, disruption in health services, increases in some infectious diseases, and acute and chronic undernutrition. 

We aim to assess the following specific health impacts in the Chilwa Basin:

  • infectious diseases: malaria, cholera, schistosomiasis, acute diarrheal disease
  • food security: protein-energy malnutrition, growth stunting in children
  • potable water, sanitation, and hygiene

To model these health impacts of climate change in Malawi, we are applying complex adaptive systems theory to develop a computer-based simulation of the following five subsystems and their interactions: 

  1. ecological services
  2. extreme weather
  3. infectious diseases
  4. food security
  5. clinical public health and disaster risk management

In cooperation with our partners in Malawi, we are selecting appropriate indicators; designing and refining the accuracy of the model; creating a monitoring and evaluation dashboard; and developing a scenario-planning toolbox. The toolbox can be used to monitor and evaluate treatment, prevention, and ecological adaptation interventions for clinical and population health.

This project is partly funded by the Wellcome Trust and involves a partnership between the Dahdaleh Institute for Global Health Research at York University and researchers from Leadership for Environment and Development (LEAD) in Malawi and from the University of California-Irvine (UCI).

Project Updates

August 2022 Workshop

In August, we held a a six-day, in-country workshop in Zomba, Malawi. The key workshop objectives were:

  1. To consolidate project achievements and identify key questions and data needed.
  2. To familiarize the project team with the study location.
  3. To introduce project team members and share project objectives and achievements with the Health and Climate Change Core Team (HCCCT) for Malawi.
  4. To discuss future collaborations with HCCCT and address key requirements for current and future projects.

May 2021 Workshop

In May 2021 we held a two-day stakeholder consultation workshop in Malawi titled Understanding the System Dynamics and Developing Causal Loop Diagrams (CLDs) of Health Impacts of Climate Change in the Lake Chilwa Basin, Malawi.

Twenty-nine participants from a range of government agencies, development partners, civil society organizations, academia, and the media discussed how to represent the subsystems in the project’s causal loop diagrams. As systems are connected through nonlinear relationships, causal loop diagrams help visualize how the different elements of a system are causally related.

Workshop participants also learned about systems dynamics and discussed how CLDs and modelling of the health impacts of climate change can inform national programs and policies.
