Chief editor
This study provides a global synthesis of vegetation resistance to drought and heat, including the roles of forest management and crop irrigation. This uniquely complete overview is valuable to further our broader understanding of vegetation and ecosystem resilience to climatic stressors.
Short summary
Ecosystem resistance reflects their susceptibility during adverse conditions and can be changed by land management. We estimate ecosystem resistance to drought and temperature globally. We find a higher resistance to drought in forests compared to croplands and an evident loss of resistance to drought when primary forests are converted to secondary forests or they are harvested. Old-growth trees tend to be more resistant in some forests and crops benefit from irrigation during drought periods.
