The document discusses the impacts of climate change on global food security and agriculture. It notes that climate change is exacerbating hunger and malnutrition by reducing crop productivity and access to food. Smallholder farmers and the poor will be most severely affected. Adaptation is needed to help agricultural systems cope with increasing climate variability, while mitigation opportunities in agriculture must be pursued in a way that benefits smallholders. International initiatives on food security and climate change need to ensure synergies between adaptation, mitigation and development.
