Climate change impacts on productivity of agroforestry systems are similar to individual perennial crops, although there is limited research on tree crops . Impacts include increased temperature or water stress, an increase in pathogens affecting crops, changes to pollinator abundance, and changes in the nutrient content of one or more of the agroforestry components. Many tree products such as fruits and nuts are grown in agroforestry settings. The quality and nutrition of these products and other specialty crops are often negatively affected by rising temperatures, ambient CO2 concentrations and tropospheric ozone . There is also evidence that the fungus coffee rust will be positively affected by climate change , with adverse effects on coffee agroforestry systems.
