“…The use of higher grazing intensities leads to spatially homogeneous canopy throughout the pasture phase, characterized mostly by excessively grazed vegetation with usual occurrence of bare soil. Furthermore, pasture cover at the end of the pasture phase affects weed infestation in the subsequent crop, since the lower the residual biomass covering the soil, the higher the incidence of weeds (Kunrath et al, 2015).…”

This paper aims to discuss the impact of the introduction of pastures and grazing animals in agricultural systems. For the purposes of this manuscript, we focus on within-farm integrated crop-livestock systems (ICLS), typical of Southern Brazil. These ICLS are designed to create and enhance the synergisms and emergent properties have arisen from agricultural areas where livestock activities are integrated with crops. We show that the introduction of the crop component will affect less the preceding condition than the introduction of the livestock component. While the introduction of crops in pastoral systems represents increasing diversity of the plant component, the introduction of animals would represent the entry of new flows and interactions within the system. Thus, given the new complexity levels achieved from the introduction of grazing, the probability of arising emergent properties is theoretically much higher. However, grazing management is vital in determining the success or failure of such initiative. The grazing intensity practiced during the pasture phase would affect the canopy structure and the forage availability to animals. In adequate and moderate grazing intensities, it is possible to affirm that livestock combined with crops (ICLS) has a potential positive impact. As important as the improvements that grazing animals can generate to the soil-plant components, the economic resilience remarkably increases when pasture rotations are introduced compared with purely agriculture systems, particularly in climate-risk situations. Thus, the integration of the pastoral component can enhance the sustainable intensification of food production, but it modifies simple, pure agricultural systems into more complex and knowledge-demanding production systems.

“…Unfortunately, long-term experimental results on possible interaction effects between system components are not yet available for integrated systems containing tree crops in Mato Grosso. In the case of crop-livestock interactions, short-term experiments have already been conducted in conditions similar to those of our study area (Landers 2007;Flores et al 2007;Silva et al 2012;Kunrath et al 2015) and suggest that the magnitude of shortterm profitability effects is rather small. Given such limited evidence, we opted for not including any interaction effects in our present model implementation.…”

Can preferential credit programs speed up the adoption of low-carbon agricultural systems in Mato Grosso, Brazil? Results from bioeconomic microsimulation

et al. 2017

The need to balance agricultural production and environmental protection shifted the focus of Brazilian land-use policy toward sustainable agriculture. In 2010, Brazil established preferential credit lines to finance investments into low-carbon integrated agricultural systems of crop, livestock and forestry. This article presents a simulation-based empirical assessment of integrated system adoption in the state of Mato Grosso, where highly mechanized soybean-cotton and soybean-maize doublecrop systems currently prevail. We employ bioeconomic modeling to explicitly capture the heterogeneity of farmlevel costs and benefits of adoption. By parameterizing and validating our simulations with both empirical and experimental data, we evaluate the effectiveness of the ABC Integration credit through indicators such as land-use change, adoption rates and budgetary costs of credit provision. Alternative scenarios reveal that specific credit conditions might speed up the diffusion of low-carbon agricultural systems in Mato Grosso.

“…The results for the height of the soybean plants in the 2012/2013 harvest were not significant and the height was 104.48 cm in the plots with one grazing, 104.13 cm in non-grazed plots and 93.75 cm in the plots with two grazings (Table 3). That is, considering the hypothesis that this has occurred because of the lower amount of DM due to grazing (Table 2) (Santos et al, 2013), or of effects on soil porosity due to the presence of animals (Flores et al, 2007;Flores & Tracy, 2012) and the water deficit period (Lopes et al, 2009), this situation tends to gradually reduce with the use of the crop rotation system in three to four years (Calonego et al, 2010), or grazing with residual height of more than 0.10 m (Kunrath et al, 2015), as can be seen in the 2013/2014 harvest (Table 3).…”
