	abstract = {Agroforestry is an age-old land use that has been practiced for thousands of years by farmers the world over. Although in recent years it has also been developed as a science that promises to help farmers increase the productivity, profitability, and sustainability of production on their land, the science of agroforestry lags far behind the art of existing agroforestry practices. However, scientific efforts to understand, classify, and improve agroforestry systems are on the increase.},
