Preserving Forests Makes Farms Better

The literature review showed that trees on farms and in agricultural landscapes in most cases result in improved food security via, e.g., reduced pest problems, improved soil fertility and water regulation. The positive effects were most consistent in semi-arid areas. In general, trees in the agricultural landscape were positive, but in some cases a decline in production of particular crops was noted as a trade-off. Very few of the available studies had investigated the production of wood, medicinal products, fruits and nuts, and no studies had looked at cultural ecosystem services such as recreation and spiritual values. This makes it difficult to establish all the synergies and trade-offs associated with trees in the landscape. (Click on title for full story.)
