Airborne imaging spectroscopy (IS) and laser scanning (ALS) have been explored widely for tree species classification during the past decades. However, African agroforestry areas, where a few exotic tree species are dominant and many native species occur less frequently, have not yet been studied. Obtaining maps of tree species would provide useful information for the characterization of agrofo...

Nitrogen (N) cycling was determined in monocultures of Sorghum bicolor (L.) Moench and alley cropped sorghum with Acacia saligna (Labill.) H. Wendl. in semiarid Northern Kenya. N input through biological N2 fixation of the acacia, N transfer from the legume to the intercrop and losses of applied N through harvest and 15 leaching were estimated using N enrichment. The biological N fixation and N...

INTRODUCTION The plant family Musaceae, composed of bananas, plantains, and ornamental bananas, originally evolved in Southeast Asia and surrounding tropical and subtropical regions (including New Guinea). Africa is a secondary center of diversity. The two genera Ensete and Musa in the family Musaceae are covered here. Please note that this manuscript is not all-inclusive and that much of the c...

Successful implementation of vegetative buffers requires inclusion of plant species that facilitate rapid dissipation of deposited contaminants before they have a chance to be transported in surface runoff or to shallow groundwater. Thirty-six field lysimeters with six different ground covers [bare ground, orchardgrass (Dactylis Received 20 October 2005, Accepted 12 June 2006 Address correspond...

Rainfall interception losses from an agroforestry system in semi-arid Kenya comprising Grevillea robusta and maize were measured over a period of 33 months. These measurements showed that interception was slightly higher (10.2%) under trees with no maize understorey, than in the intercropped treatment (9.8%), and was directly related to the degree of tree canopy cover. Interception estimates us...
