Trecs can he considered as investments made by economic agents to prevent depreciation of natural assets such as stocks of top soil and water. In agroforestq systems farmers use trees in this manner by deliberately combining them with agricultural crops on the same unit of land. Although advocates of agroforestry have asserted that soil conservation is one of its primary henefits, empirical est...

Running title: 23 Soil macrofauna in the 'Quesungual' agroforestry system 24 25 2 Abstract 26 Smallholder agroforestry systems often incorporate features that are associated with abundant, 27 diverse soil macrofauna populations. This study sampled soil macrofauna communities across 28 four major land uses present within agricultural landscapes where the Quesungual Slash-and-29 Mulch Agroforestr...

integrating natural resources management in the secondary school curriculum in kenya has received a lot of talk without adequate practical activities. the farmers of the future programme under the world agroforestry centre, formally the international centre for research in agroforestry (icraf), initiated a practical approach to integration of natural resources management in the secondary school...

This paper discusses the potential benefits from shade management in agroforestry systems for taro cropping. Trial work to evaluate weed growth, taro production, and cultivar responses to shade levels are reviewed. It is concluded that weed growth can be reduced in tree-shaded plots without reducing corm production. Higher crop biomass is obtained when taro is grown under fifty percent shade co...

abstractthe challenges of agroforestry systems’ adoption by farmers in the north central zone of nigeria, was carried out to address the following objectives; find out the perception of farmers on agroforestry technologies, identify the adoption level and ascertain why farmers discontinue agroforestry adoption.. data were collected from 722 agroforestry farmers out of 782 sets of questionnaire ...

Please cite this article in press as: Jha, S., Vander doi:10.1016/j.biocon.2010.03.017 Though it is undoubted that tropical bees are influenced by habitat composition, few studies have investigated the relative importance of both local and landscape-level habitat parameters in supporting large and diverse bee communities. The conservation of native bee communities within agroforestry landscapes...

The concept of sustainability is an underlying theme in much of the literature dealing with the economics of agroforestry. Four major areas of concern for economic investigation into sustainable agroforestry systems― profitability, dynamics, externalities, and markets―are addressed using ex­ amples from the available literature. Finally, the social constraints that farmers face when adopting ag...

Industrial or “Green Revolution” agriculture depends upon petroleum to manufacture and spread fertilizers, pesticides and herbicides and to power irrigation systems that act upon crops selected to increase agricultural yield. It has been criticized on the grounds that it has favored mainly rich farmers and caused serious environmental pollution. Now a second “Green Revolution” is being proposed...

Pacific Islands agroforestry has evolved into sustainable, diverse and productive a land use systems in many areas. We marvel at these systems, and the scientific world is trying to catch up with the traditional knowledge. At the same time, Pacific Islands farmers are abandoning their agroforestry systems in great numbers. It is mainly intensified agriculture for cash crop production that follo...

Mixed cropping (including agroforestry) often gives yield advantages as opposed to monocropping. Many criteria have been used to assess yield advantage in crop mixtures. Some of these are presented. In addition, the relative merits of replacement, additive and bivariate factorial designs are discussed. The concepts of analysis of mixed cropping are applied to an example of an alley cropping (a ...
