Climate change is threatening the world's coffee supplies: what can we do? – live chat

What we'll be discussing

Coffee production provides work for more than 120 million of the world’s poorest people. Climate change, however, is a mounting threat.

Rising temperatures in Central America are fuelling the growth of the devastating leaf disease known as coffee rust (pdf), leading to drops of 30% or more in coffee production in the region.

In Ethiopia, where an estimated 25% of the population depends directly or indirectly on coffee for their livelihoods, climate change is also having a profoundly negative impact, with production predicted to significantly decrease in certain areas.

What can be done? Join us on Tuesday 20 September, 2-3pm (BST), to debate how to protect coffee and support the people who rely on this vital commodity.

Questions we will explore include:

  • from diversifying to relocating, how can farmers become more resilient to climate change?
  • where does technology fit in?
  • who’s funding this support and how can that money be put to best use?
  • how to reach the most vulnerable coffee growing communities?
