A website dedicated to showcasing the latest scientifically-backed evidence related to climate change, agriculture and food security

almost a billion people are going hungry while we waste 1/3 of the food we produceThe CGIAR Research Program on Climate Change Agriculture and Food Security (CCAFS) does not do research for the sake of doing research. We do research for development, and in order to achieve our ambitious development goals communication is central. The way we communicate matters. It matters when we are working on-the-ground in villages discussing adaptation and mitigation options. It matters too when we publish an article on our website, make a presentation at a conference, or give an interview to the media. Through communication, we can create awareness and understanding.

But the communication of science is no easy feat. How do you simplify complex science so that it can be understood by many, rather than a few, without reducing it to meaningless nothings? How do you communicate uncertainty within science without undermining the conclusions of that science? How do you communicate consistently when science is constantly progressing and open to re-evaluation? Big Facts is part of our answer.

Big facts speak for themselves

The number of people exposed to cyclones and floods in Asia dwarfs all the other regions in the worldAs the impacts of climate change intensify, poor smallholder farmers will be among the hardest hit. But what those impacts will be and how farmers can adapt varies tremendously from region to region. While Africa faces decreases in crop productivity and changing suitability of farmlands, for Asia an onslaught of floods and cyclones is more likely.

Thankfully, adaptation options focused on local conditions already exist and are constantly improving as scientists and farmers move forward together. Often, it is the simple things that will help us adapt. In India, for instance, text message weather updates are helping farmers to make improved decisions about when to plant and harvest. Small and simple changes like this can have a huge impact on food security.

Agriculture also offers huge opportunities to reduce greenhouse gas emissions. Many of the most useful improvements to food systems help farmers to adapt to climate change and to mitigate their emissions while improving livelihoods and increasing food security – all at the same time.
