FAO's work on Climate Change

Climate change is a threat to global food security, sustainable development and poverty eradication. Greenhouse gases (GHG) from human activity are the most significant driver of observed climate change.

Climate change encompasses and goes far beyond global warming and its consequences – for example the melting of polar ice caps and glaciers leading to sea level rise. It brings about deeper implications such as extreme weather events, disruption of the water cycle, ocean acidification and changes in the function and composition of ecosystems.

The agriculture sectors that include crops, livestock, forestry, fisheries and aquaculture, must adapt to a changing climate. Improving the resilience of food production systems is key to feeding a growing population. For this reason climate change must be addressed as an integral part of the overall development agenda.

FAO's work on climate change 2016

This booklet presents FAO’s key messages on climate change and food security. It includes examples of FAO’s support to countries so they are better able to adapt to the impacts of climate change in the agriculture sectors. It also brings together FAO’s most up-to-date knowledge on climate change, including the tools and methodologies used to support countries’ climate commitments and action plans.

Mountains occupy around 22% of the Earth’s surface, and are home to about 1.2 billion people, many of whom rely on the mountains for their water supply, agriculture, hydroelectricity and biodiversity.

Around the world, mountains share a number of common features related to climate change, one being the melting of glaciers and permafrost triggering rock fall, debris and mud flow which are a serious threat to humans and livestock and can severely damage property and crops. More…
