The construction of a socio-technical approach to raise laying hens (Gallus domesticus) in agroecological systems relies on literature review, organic agriculture norms and empirical data collection. This study aims to contribute to this process applying participatory methodologies (e.g. action-research) and systemic approach to the implementation of an agroecological system by a group of small farmers from Santa Catarina State, Brazil. The theoretical and philosophical framework was defined after review of the literature where the relationship between hens and human societies in different historical periods was considered. Conceptual basis of permaculture and natural agriculture were also considered, as well as organic production standards. This study describes and examines the conception, implementation and first results of an associative project designed to produce and process organic eggs. The results are presented from a sociocultural perspective and analyses farmer's attitudes and behaviour during the conversion period. The study illustrates to what extent the choice for a specific methodological approach influences changes at farm level and its neighborhood. Therefore, it highlights the importance to apply bottom-up approach to carry out research on hens husbandry systems. The breeding activity analysis is made based on the system's structure. Hens? multifunctionality and the benefits of plant-animal interaction are the main results observed. Additionally, a field trial evaluating the behaviour of laying hens bred on pasture showed a good performance of commercial breeds. This study suggests that the conversion period should be evaluated using participatory methodologies; that is essential to invest on the training of farmers and their participation on networks; that cooperation and interchange between farmers and consumers is important; and that the impacts of activity on natural resources an welfare of the birds must be monitored.

Forest residue (i.e., litter layer, slash and bark), when used as biomass for energy production, represents an important strategy for use as a renewable energy source in many countries. However, these residues can also have importance as sources of nutrients for trees and soil conservation. The objectives of the present study were to assess the effects of forest residue management on soil, wood production and nutrient accumulation dynamics during two crop rotations in a Eucalyptus grandis plantation. Thus, we set up an experimental site with different intensities of removal, burning and incorporation of forest residues (first crop rotation of study ? R1). The stands of all treatments were harvested after eight years, and the trial was re-established with all forest residues maintained on the soil across all treatments (second crop rotation of study ? R2). R2 was conducted for eight more years. The growth and nutritional status, biomass and nutrient accumulation of the trees were assessed. The forest residue burn increased the initial nutrient availability in the soil; however, this availability returned to initial levels in a short period of time. Wood productivity decreased by approximately 40% with the removal of all forest residues in R1. In R2, wood productivity after the removal or burning of forest residues was 6% lower than when all forest residues were maintained on the soil. |
