Given the recognized role of agroforestry systems (AFS) in climate change mitigation through carbon sequestration, it is important to have rigorous and consistent procedures to measure the extent of C sequestration. The methods used currently vary widely and the estimations entail several assumptions, some of which are erroneous. Large-scale global models… (More)
Reflections on the past two decades of organized research in tropical agroforestry raise several issues. Research efforts started with an inductive and experiential approach but have subsequently followed a deductive and experimental approach that includes hypothesis testing and the development of predictive capability; agroforestry research is thus being… (More)
Historically, agroecosystems the world over have responded rather resiliently to the increasing pressure for producing food for the expanding human population. Over the years, the two major strategies for producing more food were to increase the area under crops and to increase the production per unit area. The former was the main strategy until agriculture… (More)
Guidelines in the UK require all doctors to actively take part in quality improvement. To ease future doctors into the process, formal quality improvement teaching can be delivered during medical school.
The underlying principles and traditional knowledge concerning indigenous agroforestry systems (AFS) around the world have been used successfully in the design of improved systems; but lately there has been a slow-down in that effort. Recognizing that Cinderella, by analogy, refers to an individual whose attributes were unrecognized or one who unexpectedly… (More)
Agroforestry practices, such as Shaded Coffee and Homegardens, may provide habitat for forest butterflies and contribute to their conservation in fragmented agricultural landscapes. To determine the influence of agroforestry practices in an agricultural mosaic, the distribution of fruit-feeding butterflies was studied using a systematic approach that… (More)

Questions have been raised about basic life support (BLS) training in medical education. This article addresses the research evidence behind why BLS training is inadequate and suggests recommendations for improving BLS training for medical students.
P atient populations across the world are becoming increasingly diverse, introducing a variety of health behaviours that are influenced by a patient's cultural background. Tomorrow's Doctors guidelines state that all qualified doctors must respect patients 'without prejudice', irrespective of 'diversity of background and opportunity, language, culture and… (More)
Aims and Scope Agroforestry, the purposeful growing of trees and crops in interacting combinations, began to attain prominence in the late 1970s, when the international scientific community embraced its potentials in the tropics and recognized it as a practice in search of science. During the 1990s, the relevance of agroforestry for solving problems related… (More)
