Climate change and hunger

The climate crisis is worsening. Vulnerable farmers and communities have no food security. This is how the changing climate is impacting global hunger.

Extreme weather events like floods and wildfires destroy homes and crops.

But climate change is also a big cause of hunger and malnutrition around the world. We’re in a climate crisis. This is a humanitarian emergency.

Without change, there will be famine and food crises globally due to the warming climate and biodiversity loss. Extreme weather events will become more frequent and growing seasons will be shorter.

How the climate crisis is worsening food insecurity

Climate change is causing extreme weather events like droughts, floods, wildfires. The world is reaching record high temperatures, seriously impacting how much food is available.

Extreme weather can force people to leave their homes and their livelihoods. Crops can be reduced, destroyed or fail completely. In turn, this leads to a drop in farming and food production. And less food means more hunger.

Countries across the world are experiencing more and more extreme weather leading to climate disasters. Severe drought is a leading cause of undernutrition in more than a third of countries that have seen a rise in hunger levels in the past 15 years.

In the Sahel region of Africa – which includes countries such as Niger, Mali, Chad and Burkina Faso – the rainy seasons are becoming more erratic. Droughts are leading to a decrease in food production while floods are causing outbreaks of diseases like cholera.

Climate change is a long term threat to food security and nutrition. By 2050, the risk of hunger and malnutrition could rise by 20% if we fail to reduce and prevent the adverse effects of extreme weather.

How we’re tackling hunger caused by the climate crisis

We work on long term farming and food production solutions to empower communities impacted by the changing climate. We’re teaching farmers about climate-smart growing techniques and introducing nutritious, hardy crops that can better extreme weather conditions caused by the climate crisis.

Even when rainfall is limited, it’s possible for gardens to flourish and provide enough to feed families and livestock. With the help of innovative techniques, our teams are helping farmers grow more crops with less water.

Improving soil

Healthy soil means crops that thrive. In Pakistan we’re introducing crops like sugar beets, which can help reduce salt levels in soil

Real-time alerts for farmers

We’re helping herders and farmers dodge drought by creating an innovative system of real-time alerts that help them find better grazing land.

Creating farmer co-operatives

We also set up farmer co-operatives so farmers can rent larger plots of land for farming. Like in Uganda, where farmers can get together to negotiate fair prices for their produce.

Harnessing solar power

During a drought or a heatwave, the sun beats down on rural communities. But by using solar power that energy can be turned into a force for good to fuel everything from water pumps to irrigation systems.

And while we focus on helping communities prepare for crises and help build their resilience, we’re also ready to step in with emergency help when needed.

The human face of climate change

Climate change is fuelling a global hunger and nutrition crisis that is exacerbating existing inequalities and has severe, compounding impacts on women and girls. Here are our asks for addressing the malnutrition crisis at COP29.
