Cocoa cultivation is generally considered to foster deforestation. Contrary to this view, in the forest–savannah interface area in Cameroon, farmers have planted cocoa agroforestry systems on Imperata cylindrica grasslands, a soil-climate zone generally considered unsuitable for cocoa cultivation. We undertook a survey to understand the agricultural and ecological bases of this innovation. Age, cr...... hiện toàn bộ
Productivity and nutrient cycling in young Acacia senegal farming systems on Vertisol in the Blue Nile region, SudanAgroforestry Systems - Tập 68 - Trang 193-207 - 2006

Acacia senegal, the gum arabic-producing tree, is the most important component of traditional dryland agroforestry systems in the␣Sudan. The spatial arrangement of trees and the type of agricultural crop used influence the interaction between trees and crops. Tree and crop growth, gum and crop yields and nutrient cycling were investigated over a period of 4 years. Trees were grown at 5 × 5 m and 1...... hiện toàn bộ
Farm-SAFE: the process of developing a plot- and farm-scale model of arable, forestry, and silvoarable economicsAgroforestry Systems - Tập 81 - Trang 93-108 - 2010

Financial feasibility and financial return are two key issues that farmers and land owners consider when deciding between alternative land uses such as arable farming, forestry and agroforestry. Moreover regional variations in yields, prices and government grants mean that the relative revenue and cost of such systems can vary substantially within Europe. To aid our understanding of these variatio...... hiện toàn bộ
Modelling tree density effects on provisioning ecosystem services in EuropeAgroforestry Systems - Tập 93 - Trang 1985-2007 - 2018

Agroforestry systems, in which trees are integrated in arable or pasture land, can be used to enable sustainable food, material, and energy production (i.e. provide provisioning ecosystem services) whilst reducing the negative environmental impacts associated with farming. However, one constraint on the uptake of agroforestry in Europe is a lack of knowledge on how specific agroforestry designs af...... hiện toàn bộ
Contrasting rooting patterns of some arid-zone fruit tree species from Botswana – II. Coarse root distributionAgroforestry Systems - Tập 64 - Trang 13-24 - 2005
Armin L. Oppelt, Winfried Kurth, Douglas L. Godbold
Spatial coarse root distribution of the in situ grown species Strychnos cocculoides Bak., Strychnos spinosa Lam. (Loganiaceae), Vangueria infausta Burch. (Rubiaceae) and Grewia flava DC. (Tiliaceae) was investigated. The woody roots provide the scaffolding for fine roots, and thus underpin potential competition with fine roots of other species. We developed a method for quantitative description of...... hiện toàn bộ
