Todos os textos, informa??es e resultados apresentados s?o de inteira responsabilidade dos autores.Objetivou-se avaliar o n?mero de perfilhos do capim-marandu em cons?rcio com milho, cultivado em diferentes
arranjos de eucalipto em sistemas agrossilvipastoris, estabelecido h? cinco anos. O experimento foi conduzido na Universidade Federal de Vi?osa, MG, em um sistema agrossilvipastoril no in?cio de degrada??o do pasto.
Utilizou-se o delineamento experimental em blocos completos casualizados, com tr?s repeti??es e os tratamentos
consistiram do arranjo fatorial (3x2)+1, sendo fator A: cultivo de brachiaria brizantha cv. Marandu (capim-marandu) com dois h?bridos de milho (BM207, com folhas planiformes e BM502, com folhas eretas) e o capim-marandu em sistema silvipastoril e o fator B os dois espa?amentos entre ?rvores de eucalipto (12x2 e 12x4 m), e
a testemunha em pleno sol (monocultivo). O n?mero de perfilhos foi estimada a partir da contagem total de
perfilhos no interior de uma moldura de vergalh?o de 1,00 m de lado, alocada no interior da parcela na quando o
milho apresentava gr?os pastoso farin?ceo (?poca de colheita de milho para ensilagem). O n?mero de perfilhos
da Brachiaria brizantha cv. Marandu ? maior em sistemas que combinam h?bridos de milho de arquitetura foliar
ereta, espa?amentos entre ?rvores maiores (12x4) e para os sistemas silvipastoris.It was aimed to assess the number of marandugrass tillers in consortium with corn grown in different eucalyptus
arrangements in agroforestry systems, from five years ago. The experiment was conducted at the Universidade
Federal de Vi?osa,in Minas Gerais, in an agrosylvopastoral system at the beginning of pasture degradation. We
used the experimental design in randomized complete block, with three replications and the treatments consisted
of a factorial arrangement (3x2)+1, factor A being: cultivation of Brachiariabrizantha cv. Marandu
(marandugrass) with two corn hybrids (BM207, with flat leaves and BM502, with erect leaves) and
marandugrass in silvopastoral system and factor B: two spacing between eucalyptus trees (12x2 and 12x4
meters), and the witness in full sun (monoculture). The number of tillers was estimated from the total count of
tillers inside a framerebar of 1,00 meterwide, allocated inside the parcel when the corn had pasty chalky grains
(time of harvest corn for silage). The number of Brachiariabrizantha tillers cv. Marandu is higher in systems
that combine corn hybrids of erect leaf architecture, spacings between larger trees (12x4) and for silvopastoral
systems

It was aimed to evaluate the morphological composition of marandugrass in establishing marandugrass pastures
after renovation of agroforestry systems with eucalyptus. The experiment was conducted at the Federal
University of Vi?osa, in Minas Gerais, in an agrosylvopastoral system at the beginning of pasture degradation.
We used the experimental design in randomized complete block, with three replications and the treatments

determining the dry mass of green leaf blades (% GLB) and green culms (% GC). Morphological composition of
Brachiaria brizantha cv. Marandu changes in systems that combine corn hybrids with erect leaf architecture and
spacings between larger trees (12x4) with highest percentage of leaf blades. The agroforestry systems are a
potential alternative for recovering degraded systems, improving the morphological composition of the pasture

corn hybrids and in eucalyptus arrangements in agroforestry, silvopastoral and in full sun systems, in an
agrosylvopastoral system from five years ago. We used the experimental design in randomized complete block,
with three replications and the treatments consisted of a factorial arrangement (3x2)+1, factor A being:

production (DM) was estimated at 90 and 150 days after corn harvest. There was a higher DM production of
marandugrass in the arrangements of most tree spacing. The pasture recovery through agroforestry systems is an
alternative in the recovery of degraded systems, given their productive potential

Establishing the health and wellbeing needs of mining host community in Brazil, Chile and Peru: a mixed-method approach to identify priority areas for action to help communities meet their SDG3 targets
Background
The global mining industry is an important partner in advancing the 2030 Agenda for Sustainable Development. In 2018, Anglo American plc published their Sustainable Mining Plan, containing a goal for improving health and wellbeing aligned with the Sustainable Development Goal 3 (SDG3) targets. Having formed an independent multidisciplinary research consortium, we designed and implemented a mixed-methods approach to attain a deeper understanding of SDG3 priorities within the local context of communities hosting Anglo American mining operations located in Latin America.
Methods
In 2019, within the host communities of three mining operations in Chile, three in Brazil, and one in Peru, we conducted a qualitative study which included stakeholder workshops and key informant interviews. We also quantitatively appraised existing health data. Findings emerging from the qualitative and quantitative assessments were compared to identify health and wellbeing priority areas for action relevant to each community.
Results
Across the three countries, 120 people took part in workshops and 35 in interviews. In these workshops and interviews, non-communicable diseases (SDG3.4), harmful alcohol consumption (SDG3.5), and pollution, particularly air pollution (SDG3.9), were consistently identified as areas for priority action. There were similarities in the reporting of individual, interpersonal, community, societal, and structural factors underlying these priority areas across the different communities. The availability of quantitative data was generally good at the state level, becoming increasing sparse as we focused on smaller geographies. The priorities identified in the quantitative assessments generally aligned with those highlighted in the qualitative data.
Conclusions
We highlight the importance of engaging with local populations to understand and address health needs. To address the priorities identified, intervention packages tailored to the specific needs of host communities, that tackle associated upstream societal level factors, are required. To facilitate this, appropriate monitoring systems and epidemiological investigations should be implemented to better understand the local context and quantify health issues. In the host communities, it is essential for the mining sector to be a key health partner in promoting integrated programmes that contribute to achieving the priority objectives and targets aligned with the SDG3 agenda

BM207, com folhas planiformes e triplo ? BM502, com folhas eretas) em cons?rcio com a Brachiaria brizantha
cv. Marandu (capim-marandu), dois espa?amentos entre ?rvores de eucalipto (12x2 e 12x4 m), e os dois h?bridos
de milho em monocultivo. Aos 110 dias ap?s a semeadura, ?poca de gr?os pastoso farin?ceo, foram
determinadas as alturas de plantas de milho em tr?s diferentes distancias das ?rvores (2, 4 e 6 m) e determinada a
m?dia entre as tr?s diferentes distancias, em cada unidade experimental. A altura dos h?bridos de milho foi
influenciada pelas dist?ncias das ?rvores, pelos diferentes espa?amentos das ?rvores e entre os h?bridos utilizados
nos sistemas em agrossilvipastoris j? estabelecidos h? cinco anos.ABSTRACT
It was aimed to evaluate the height of corn plants at different distances from eucalyptus trees in consortium with
marandugrass, grown in different eucalyptus arrangements in agroforestry systems, from five years ago. We used
the experimental randomized complete block design, with three replications and the treatments consisted of a
factorial arrangement (2x2) +2, two corn hybrids (double - BM207 with planiformes leaves and triple - BM502,
with erect leaves) in consortium with Brachiariabrizantha cv. Marandu (marandugrass), two spacing between
eucalyptus trees (12x2 and 12x4 meters), and the two corn hybrids in monoculture. At 110 days after sowing,
period of pasty chalky grains, it was determined the height of corn plants in three different distances from the
trees (2, 4 and 6 meters) and it was determined the average of the three different distances in each experimental
unit. The height of the corn hybrids was influenced by the distances of the trees, by different spacing from the
trees and among the hybrids used in the systems agroforestry from five years ago
