“…Dairy and livestock production in combination with direct seeding (no‐tillage system) represent a rather common land use on highly‐weathered clay soils in southern Brazil (Telles et al, 2020), and significantly contribute to meet the growing regional demand for food. Despite high economic importance, this land use comes with noteworthy implications for the environment in terms of water resources and water quality (Ruviaro et al, 2020). Conservation agriculture is of utmost importance (Andrade et al, 2012; Hollanda et al, 2015) with special regard to pollution (Becker et al, 2009; Broetto et al, 2017; Klippel, 2016; Sharma et al, 2018) for environmental planning and management (Bastos et al, 2021; Minella et al, 2007; Minella et al, 2022; Santos et al, 2016).…”

A 3-year study on erosion and streamflow was conducted in two adjacent paired watersheds that flow into the Passo Real reservoir, one of the largest and most important reservoirs for human water supply and power generation in southern Brazil. The watersheds have similar land use and soil management, but different size and riparian vegetation. The first objective of the study was to monitor and evaluate hydrosedimentological dynamics and effects of riparian vegetation, over a range of rain events, in the two watersheds; the second was to assess the ability of the Limburg Soil Erosion Model (LISEM) to represent these small watersheds in hydrosedimentological terms (runoff and erosion) under individual rain events, in the context of better understanding the role of riparian vegetation and land cover. LISEM is a hydrological model structured on physically based equations that can be used for planning and conservation purposes. Studied rainfall events between 2016 and 2018 had a wide range in total rainfall (10-170 mm), rainfall intensity in 1 h (3-66 mm h À1 ), stream peak flows (4-5741 L s À1 ), runoff volume (0.02-40 mm), runoff coefficient (0.1-32%), maximum suspended sediment concentration (20-19 611 mg L À1 ), and sediment yield (0.002-33.790 Mg km À2 ). Both watersheds showed a rapid response to rain events with significant runoff generation. Abundance of unpaved roads (often parallel to the slope) promoted high runoff due to channelization effects. South Watershed has 59% more riparian vegetation than North Watershed, but this greater riparian vegetation was not effective in reducing surface runoff and erosion. Furthermore, local adoption of no-tillage was insufficient to control runoff and sediment yield.

“…Dairy production contributes to nearly 70% of the total income on dairy farms in southern Brazil (Costa et al, 2013), demonstrating the importance of accurate decisions to minimize high production costs. Feeding costs contribute with approximately 60% of the total variable costs for pasture-based farming system (Ruviaro et al, 2020). As a result, it is crucial to characterize better strategies, especially…”

Animal production systems and agribusinessFull-length research article Use of quali-quantitative feeding practices criteria in typology of smallholders' dairy production systems ABSTRACT -This study aimed to typify smallholders' dairy systems using qualiquantitative measures of feeding practices and detect the main discriminatory elements identifying the systems. We collected data from 30 farms distributed in 10 municipalities in the eastern region of Rio Grande do Sul, Brazil, using a survey with semi-structured questions, in addition to bimonthly observations of milking and feeding practices. Multivariate analysis based on principal factors and cluster analysis were performed. Multiple linear regressions were made between the principal factors scores and variables of milk production and composition. Three principal factors with eigenvalues ≥1.0 explained 58.9% of the total variance. The original variables with the highest factor loading values were production scale and feeding practices involving greater quantities of byproducts; use of corn silage and sugarcane; and commercial and farm-made concentrate for principal factor 1, principal factor 2, and principal factor 3, respectively. Milk yield and concentrations of lactose and solids non-fat increased linearly with principal factor 1 and principal factor 3 but decreased linearly with principal factor 2. Observations were grouped into three clusters. Farm area and quantity of corn silage and byproducts were the most important variables to set the clusters. The use of quali-quantitative feeding practices criteria to characterize dairy systems is effective to identify the opportunities for improving milk production and composition. Whereas high inclusion of sugarcane as roughage was detrimental for milk production, moderate supply of concentrate and byproducts enhanced milk yield without compromising milk composition.

“…Recently, Brazilian LCA studies on milk and dairy products of buffalo (Soares et al 2019 ; Alves et al 2019 ) and goat (Cabral et al 2020 ) have been published. Moreover, Ruviaro et al ( 2020 ) used the life cycle perspective to assess economic costs by dairy production systems in Southern Brazil. However, no study regarding the environmental impacts of cow milk could be found.…”
