| Long term applications of leguminous green mulch could increase mineralizable nitrogen (N) beneath cupuaçu trees produced on the infertile acidic Ultisols and Oxisols of the Amazon Basin. However, low quality standing cupuaçu litter could interfere with green mulch N release and soil N mineralization. This study compared mineral N, total N, and microbial biomass N beneath cupuaçu trees grown in two different agroforestry systems, north of Manaus, Brazil, following seven years of different green mulch application rates. To test for net interactions between green mulch and cupuaçu litter, dried gliricidia and inga leaves were mixed with senescent cupuaçu leaves, surface applied to an Oxisol soil, and incubated in a greenhouse for 162 days. Leaf... |

| We studied the management of the fiber-producing chambira palm Astrocaryum chambira by indigenous people in the Colombian Amazon. Between 2009 and 2012, we visited four communities and two marketing centers, where we interviewed 12 people. In addition, we specifically observed A. chambira harvesting, processing, and commercialization; studied palm populations at five localities; measured leaf production rate; and integrated secondary data. At least 21 aboriginal groups in the Colombian Amazon use chambira fiber. The palm grows in association with human communities, and it has been widely used and managed in past agroforestry systems. The fiber is obtained from the unexpanded leaves of juvenile or adult palms, and harvesting is often unsustainable because... |

| This study aimed to evaluate the shading influence on production and qualitative traits of four tropical forage legumes (calopo, puero, archer and perennial soybean). Legumes were cultivated under levels of artificial shading (0; 30; 50 and 70%) from January 2006 to June 2007. Dry matter production (DM), crude protein (CP), neutral detergent fiber (NDF), cellulose (CEL), hemicellulose (HEM) and lignin contents were evaluated. In the summer, increases in legumes DM yield were observed when grown under increasing shading levels. Calopo, puero, and archer production showed quadratic effect. Regression analysis derivation for dry matter yield showed levels of maximum values at 35.0; 33.78 and 45.45% in the summer and 34.94; 34.83 and 33.29% in the fall.... |

| Modifications on leaf anatomy in Coffea arabica shaded with pigeonpea (Cajanus cajan), compared to cultivation under full sun, were assessed. The leaves fully exposed to sunlight presented thicker cuticles and cellular walls, narrower epidermis cells, palisade parenchyma with longer cells, thicker lacunar parenchyma, fewer intercellular spaces and a larger stomata number. Leaves under dense shade presented a narrower cuticle and cellular wall; a mesophyll with smaller volume, but with larger intercellular spaces; and epidermis with thicker cells and a smaller stomata amount, surrounded by subsidiary cells of smaller dimensions. Plants grown under full sunlight presented higher values of net photosynthesis. The results evidenced that the species C. arabica... |

| Tree seedling survival rates are low in the dry, harsh climate of the Bolivian altiplano. We tested two species, Polylepsis tarapacana and Cupressus macrocarpa, using four microcatchment planting methods and a control to determine if species survival could be improved. The control improved surface infiltration rates but provided no protection from wind and cold. The four sub-surface planting methods increased soil moisture and mitigated cold, desiccating winds. The native species, P. tarapacana, showed better survival than the non-native one. All planting methods showed excellent survival rates for P. tarapacana, as all methods improve rainfall infiltration in relatively poor soil. Pit planting proved to be more successful for C. macrocarpa than other... |

| Access to knowledge on farm management practices is essential for the maintenance of productive agroforestry systems. Farmers who lack the means to acquire farming knowledge from formal sources often rely on information within their informal social networks. However, little research has explored the explicit structure of farmer communication patterns. We examined advice network structures by using farmer attributes, i.e., kin relationships, community involvement, and imitation, to characterize structural positions and investigated the consequences of such structure on farming practices in cocoa agroforestry systems in Ghana, West Africa. Furthermore, we used a multicommunity approach; we constructed networks for four communities to increase replication... |

| Serious methodological and policy hurdles constrain effective natural resource management that alleviates poverty while protecting environmental services in tropical watersheds. We review the development of an approach that integrates biodiversity conservation with agroforestry development through the active involvement of communities and their local governments near the Kitanglad Range Natural Park in the Manupali watershed, central Mindanao, the Philippines. Agroforestry innovations were developed to suit the biophysical and socioeconomic conditions of the buffer zone. These included practices for tree farming and conservation farming for annual cropping on slopes. Institutional innovations improved resource management, resulting in an effective social... |

| The trade-off between economically critical provisioning services and environmentally sustaining supporting services often seems absolute. Yet, when land use is inefficient, managers may be able to increase provision of both economically and ecologically sustaining services. To explore such sustainable "win-win" outcomes, I present a model of predicted trade-offs of provisioning and supporting services on smallholder farms in eastern Paraguay. The spatially implicit model simulates smallholder parcels as mosaics of subsistence agriculture, cattle pasture, eucalyptus plantations, and/or natural forest cover, and predicts provisioning and supporting service supply depending on the relative abundance of each land-use type per parcel. I represent provisioning... |

| Environmentally induced farmer migration is an important livelihood strategy, yet little is known of the effects on the destination region agroecosystem information networks and management practices. In the forest-savanna transition zone (Brong Ahafo Region) of Ghana, where migration from northern regions (migrant) and from neighboring regions (settler) is active, we chart the role of migrant famers and the type of agroecosystem management practices embedded in information networks using a social networks approach. Based on empirical network data from 44 respondents across three communities, we illustrate a diffuse information network, with variable tie frequency between settlement categories (local, settler, or migrant) of farmers. The cohesion of this... |

| O sistema Integração Lavoura Pecuária e Floresta (ILPF) é uma estratégia de cultivo que objetiva a produção sustentável, integrando atividades agrícolas, pecuárias e fl orestais na mesma área, em cultivo consorciado, em sucessão ou rotacionado, e busca efeitos sinérgicos entre os componentes do agroecossistema, contemplando a melhoria ambiental, a valorização dos seres humanos e a viabilidade econômica. Em outras palavras, o sistema ILPF consiste na diversifi cação de cultivo, de forma que o produtor consiga, além de melhorar sua renda, conservar o solo e água da propriedade, melhorando suas condições de cultivo ao longo do tempo, e com melhor aproveitamento de água da chuva. Através deste sistema, o produtor, sendo familiar ou empresarial, tem a... |
