Objectifs
To determine the impacts of trees and shrubs in the agricultural landscape and to describe these impacts in terms of the ecological and economic benefits that flow from these systems. To describe the 3 dimensional structure of a windbreak and its effect on windflow and microclimate. To determine the amount of biomass and carbon carbon stored in a field windbreak and the increase in fuel efficiencies associated with wind protection. To develop and integrated farm system containing alley cropping, shelterbelts, and silvo pastoral practices.

Descriptif
Surface area and volume and their arrangement in a field shelterbelt have been determined. These values will be used to describe the structure of a windbreak and then used to assess the impact on wind speed reduction and the resulting microclimate. Yield studies will determine the agronomic effect and the impacts used to determine economic return. Field surveys will be used to assess the amount of biomass stored in windbreaks and forested riparian buffers. Their potential for carbon storage will be determined. Simulation models will be used to expand the applicability to other situations
