|Título:||Social and economical evaluation of innovative alley coppice systems mixing timber trees with bioenergy wood crops in agroforestry systems|
|Resumo:||Alley coppice (AC) is an innovative agroforestry system where high value timber trees in lines are intercropped with bioenergy short rotation coppice (SRC). AC potentially provides several production and environmental benefits, although so far these are poorly investigated. Thus, research on farmer interest in AC systems, and preliminary economic evaluations, have been made on the AgroCop European project (www.agrocop.com). A questionnaire was conducted with farmers in Italy to identify and assess their interests and concerns regarding AC systems. Farmers appeared to be familiar with managing forest plantations as species mixtures and the value of fuelwood. However, the value of the timber and biomass produced during the rotation appeared to be farmers’ main source of uncertainty, with no clear idea of what demand there would be for both wood products, and they assigned a higher rank to the importance of environmental benefits (biodiversity, landscape, soil fertility improvement). This indicated that there was a need to study the economic performance of the AC system developing two tools: a simplified economic calculator for stakeholders, that can estimate and compare net present value (NPV) of different AC systems, and a more complex model, adapting FarmSAFE. Biophysical data was generated using LERSAFE. Wood chips from the SRC component were found to have a low market value, and AC profitability depends mostly on the timber trees, with the essential need to optimize revenue from the valuable timber, especially by maximizing its quality. Therefore, the SRC component has an important role to play in increasing the quality of the valuable timber by improving timber tree form, reducing the costs of management operations and for giving a revenue during the growth of standard trees. AC could be an innovative option for timber and bioenergy production, integrating some of the advantages that are characteristic of agroforestry systems into mixed tree plantations.|
