| In the context of global warming and climate changes, livestock production systems may be beneficial or prejudicial to the environment considering they can act as sinks or sources of greenhouse gases - GHG. This makes the carbon - C - balance a fundamental tool in the evaluation of these systems. Carbon balance results must be compared with caution due to differences in the calculus methodology and in the range of processes considered for the anthropic emissions and sequestrations of C. Generally, degraded pastures are not able to neutralize GHG emissions by C sequestration in the soil while intensive pasture systems, integrated or not, have the potential to mitigate GHG and neutrale beef C footprint, generating C credits. Integrated systems have an... |

| ABSTRACT. Canopy height (CH) is one of the key parameters used to evaluate forage biomass production and support grazing management decisions in intensively managed fields. In this study, we demonstrate the potential of using textural information derived from PlanetScope (PS) imagery to estimate CH of intensively managed mixed pastures in an Integrated Crop-Livestock Systems (ICLS) in the western region of São Paulo State, Brazil. PS images and field data of CH were acquired during the forage growing season of 2019 (from May to November) to calibrate and validate the CH prediction models using the Random Forest (RF) regression algorithm. We used as predictor variables eight second-order texture measures derived from the green, red, near-infrared spectral... |

| The level of diffusion of integrated croplivestock systems (ICLS) and integrated livestockforestry systems (ILFS) among cattle farmers in Brazil is still low, despite the environmental and economic benefits and governmental policy support. The present study aims at identifying the factors that determine the adoption of these systems in the State of São Paulo, Brazil. The theory of adoption and diffusion of agricultural innovations takes into consideration several economic and non-economic determinants. Data from 175 farms and multinomial logit models were used to test hypotheses on the role played by farms?scale, farms? topography, farms? type of soil, farmers? knowledge, farmers? capacity for innovation, availability of local facilities for grain trade,... |

| ABSTRACT The objective with this study was to calculate the total cost of maize production and beef cattle in permanent pasture activities in separate production systems (conventional) and integrated systems (maize production plus beef cattle), as well as to verify economic gains explained by the economy of scope. The first step for the development of the research was to obtain field experimental data. Six experimental treatments were studied: corn grain production, beef cattle in permanent pasture, and four integrated systems based on different crop and pasture sowings. The second step consisted in the collection, calculation, and allocation of variable and fixed costs to estimate costs of production in the systems. The crop-livestock integration showed... |

| Os sistemas integrados de produção lavoura-pecuária (SIPAs) em associação ao sistema de semeadura direta, sofrem ação do pisoteio animal ou do tráfego intenso de máquinas agrícolas, podendo resultar em alterações nas propriedades físicas do solo. O objetivo deste trabalho foi avaliar o efeito da adubação nitrogenada e manejos das forrageiras tropicais nas propriedades físicas do solo. O experimento foi realizado entre outubro de 2017 e janeiro de 2020, em Marechal Cândido Rondon – PR, em blocos ao acaso, com parcelas sub-subdivididas com uma testemunha adicional e quatro repetições. As parcelas foram constituídas por duas espécies forrageiras consorciadas com o milho: Urochloa brizantha e Magathyrsus maximum, mais a testemunha adicional (milho solteiro).... |

| The former extensive polyculture systems of marine fish farming, are today replaced mainly by intensive monoculture systems (salmon, shrimp). These systems, multiplied in the same coastal zone, can present a significant environmental impact. To treat and value fish farming effluents, new integrated systems were constructed and tested to different scales. Some examples of land- and seabased systems around the world are presented, in particular the European project of innovation "Genesis" in which several French public and private, national and regional organisations are participants (IFREMER, Regional Centre of Experiment and Aquacultural Applications in Poitou- Charentes, IDEE). Recommendations are supplied to promote the development of the integrated fish... |

| O objetivo deste trabalho foi avaliar índices de conforto térmico em sistemas de integração lavoura-pecuária-floresta, com eucalipto em arranjos de 14x2m (ILPF-1) e de 22x2m (ILPF-2) e árvores nativas dispersas com 5 árvores/ha-1 (ILPF-3), no Município de Campo Grande, Mato Grosso do Sul. O experimento foi conduzido na Embrapa Gado de Corte, em Campo Grande, MS, de julho a setembro de 2013. As avaliações foram realizadas mensalmente, em quatro dias consecutivos, em três horários (09h00, 12h00 e 15h00; GMT -04h00). Foram determinadas a temperatura do ar (°C), temperatura de globo negro (°C), temperatura de bulbo úmido (°C), umidade relativa do ar (%) e velocidade do vento (m s-1). Foram calculados o Índice de Temperatura e Umidade (ITU), Índice de... |

| Abstract: Fast and accurate quantification of the available pasture biomass is essential to support grazing management decisions in intensively managed fields. The increasing temporal and spatial resolutions oered by the new generation of orbital platforms, such as Planet CubeSat satellites, have improved the capability of monitoring pasture biomass using remotely sensed data. Here, we assessed the feasibility of using spectral and textural information derived from PlanetScope imagery for estimating pasture aboveground biomass (AGB) and canopy height (CH) in intensively managed fields and the potential for enhanced accuracy by applying the extreme gradient boosting (XGBoost) algorithm. Our results demonstrated that the texture measures enhanced AGB and CH... |

| Abstract: The objective of this work was to evaluate the performance of crossbred steers post-weaned in an integrated crop-livestock system (ICL) and finished in a feedlot, fed either a high-level concentrate diet or whole corn with no roughage. Weaned calves of two breed groups - ½ Angus × ½ Nellore, and ½ Charolais × ¼ Angus × ¼ Nellore - were allotted in a completely randomized experimental design (CRD). During the rainy season, the ½ Angus × ½ Nellore animals showed a higher performance than the ½ Charolais × ¼ Angus ×¼ Nellore ones, with 0.748 and 0.490 kg average daily gain, respectively. The productivity in the post-weaning period was 926 kg ha-1 body weight in a 11-month period, in the ICL system. Subsequently, the animals were confined and fed... |

| Peltophorum dubium canbe an alternative of forestry species to be includedin integrated crop-livestock-forestry systemsin tropical region. The aim of thisresearch was to evaluate the performanceof P. dubiumunder intraspecific tree competition and cardinal directions to measure the possibility of introduction in integrated livestock-forestry systems.The experiment was performed in a Nelder Wheel competition, which is used in forestry research to test tree competition. The experimental design was factorial (10×2×5) with 12 replicates. The treatments were accomplished by tentree competitions (159, 201, 255, 322, 408, 516, 653, 827, 1,046 and 1,324 trees ha-1), two cardinal directions (North-South and East-West) and five times after planting (12, 18, 24, 30... |
