Climate change and food security: risks and responsesx
This report serves three purposesClimate change and food securityx
This report serves three purposes.
First, to raise awareness that climate change is already impacting the food security and
nutrition of the most vulnerable, and that if action is not very quickly taken, climate change
will increasingly threaten the achievement of the goal to eradicate hunger. This is one more
reason for governments to take ambition action to tackle climate change in all sectors.
Second, to describe precisely the pathways by which climate change finally impacts the food
security of people, and to show the range of actions needed. Understanding these pathways
and the potential responses, not only technical, but also from social protection to strengthened
international cooperation, is indispensable. It grounds FAO’s action to eradicate hunger
and malnutrition.
Third, it also aims to fuel the ongoing discussions on how to operationalize adaptation to
climate change, and to show that food security and nutrition, as well as the agriculture sectors
that support it, should be a priority area of intervention. As such, it also aims to answer the
adaptation needs and demands conveyed by many countries in their Intended Nationally
Determined Contributions for COP21.
This report brings together evidence from the IPCC, updated by the latest scientific findings
and enriched by FAO’s knowledge and experiences on the ground. It provides an overview of
the cascading impacts of climate change on food security and nutrition, from physical impacts
on agro-ecosystems to livelihoods and food security. It describes how the cascade of impacts
acts on a series of vulnerabilities. It presents ways to adapt and build resilience to climate
change to ensure food security and nutrition. It shows the importance to act now on climate
change: to eliminate hunger; to enable the agriculture sectors to adapt to climate change. It
also recalls the urgency to mitigate climate change in order to keep it at levels where it is still
possible to ensure and safeguard everyone’s food security and nutrition.
