The ATACH Working Group on Climate Action and Nutrition (I-CAN-WG)

Climate change and malnutrition in all its forms are two of the greatest challenges facing humanity today and are intrinsically intertwined. By addressing these two priorities in an integrated way, we have one solution to two of our biggest barriers to sustainable development. Climate change is impacting food systems, health systems, social protection systems and water systems - all of which are fundamental for good nutrition. At the same time, inefficiencies and maladaptation in these four systems are further contributing to the drivers of climate change, namely greenhouse gas emissions and the degradation of natural resources. The impacts and exposure to risk factors of climate change and nutrition are not gender neutral. Inequalities in access to health and nutrition services and social protection, control over resources, agency and decision-making power are underlying drivers of malnutrition and climate change. As a result, women and girls are differently exposed and have different abilities to respond to or cope with shocks.

The establishment of this working group was prompted by the launch of the Initiative on Climate and Nutrition (I-CAN), which focuses on the intersection of climate change and nutrition. For a comprehensive description of the I-CAN's specific goals and activities, a concept note and a narrative are available. 

Through coordination and collaboration, the ATACH Working Group on Climate Action and Nutrition (I-CAN-WG) strives to help foster collaboration to accelerate transformative action to address the critical nexus of climate change and nutrition. 

This working group will primarily focus on the first commitment area of the COP26 Health Programme.

The I-CAN-WG meets at least twice a year to achieve its key objectives and help countries meet their commitments. Its objectives include:

  • Build a strong alliance across nutrition and climate communities.
  • Articulate a common, compelling narrative around climate and nutrition.
  • Develop and share evidence on integrated nutrition and climate action.
  • Strengthen existing efforts and take action to address gaps.

The I-CAN-WG Workplan

  • Build a strong alliance across nutrition and climate communities;
  • Improve advocacy to increase action toward linkages between climate and nutrition;
  • Develop and share evidence-base on integrated nutrition and climate action;
  • Stewardship;
  • Mobilize resources for I-CAN; and
  • Articulate a common, compelling narrative around climate and nutrition.
