The document outlines 3 key challenges related to climate change: food security, adaptation, and reducing agriculture's environmental footprint. For food security, the length of growing seasons is projected to decline in many areas by 2090, leading to increased food prices. Climate change will exacerbate existing food price rises. For adaptation, industries like Australian wine may need to relocate to cooler regions. Future farms may use climate analogues and diversification. For mitigation, green development pathways are needed that don't compromise food security, and carbon markets could provide incentives for monitoring and verification of technical practices.

3. Challenge 1: Food security

4. Challenge 2: Adaptation

5. Length of growing season is likely to decline.. Length of growing period (%) >20% loss 5-20% loss No change 5-20% gain >20% gain To 2090, taking 18 climate models Four degree world Thornton et al. (2010) ILRI/CCAFS
