Climate change presents a serious threat to nutrition and food security. Earlier this year, the World Food Programme made bleak predictions underlining the connection between the two issues. With climate change increasing the risk and intensity of climate disasters such as floods and drought, unless huge efforts are made to increase climate resilience, the risk of hunger and malnutrition could increase by 20% by 2050. It is also a two-way relationship. An estimated 25% of the world’s greenhouse gases are produced from global food systems, of which half comes from food production and the other from transportation, packaging, processing and land use for agriculture.

With world leaders preparing to descend on Paris for climate talks at COP 21, there is clearly an opportunity to make progress on both issues. What are the practical solutions to tackling climate change, while improving nutrition and food security? And what are the challenges involved?

Join an expert panel on Thursday 26 November, 1-3pm GMT, to discuss these questions and more.

The live chat is not video or audio-enabled but will take place in the comments section (below). Get in touch via globaldevpros@theguardian.com or @GuardianGDP on Twitter to recommend someone for our expert panel. Follow the discussion using the hashtag #globaldevlive.
