Agroforestry as a Strategy to Climate Change Adaptation Adaptation capabilities of agroforestry • Drought :Tree components through their deep roots explore a large soil volume of water and nutrients which help to maintain production during drought seasons • High rainfall :Pumping excess water out of the soil They can be defined as those land use systems which involve two main components - trees/shrubs and an agricultural crop (which could also be pasture) and are / Component interaction refersto the influence of one component of a system on the performance ofothercomponent.
