Do Large Slaughterhouses Promote Sustainable Intensification of Cattle Ranching in Amazonia and the Cerrado?

This study investigated the influence of large slaughterhouses on five variables, two related to environment impact (land use change rate and greenhouse gases emissions (GE)), and three related to cattle-ranching intensification (protein from crops, calories from crops and stocking rate). In Amazonia, the results show a reduction of the land use change rate and GE in zones both with and without the influence of large slaughterhouses. The hypothesis that slaughterhouses are leverage points to reduce deforestation in the biome was not confirmed. The slaughterhouses also seem to have no effect on cattle ranching intensification, as protein and calories production increased significantly in both zones, while the stocking rates did not change in the influence zones. In the Cerrado, cattle-ranching intensification is a reality, and is occurring independently of the presence of large slaughterhouses. In conclusion, the results show no evidence that large slaughterhouses have promoted either cattle-ranching intensification or improvements in the sustainability of the cattle-ranching activity in Amazonia and the Cerrado.

Historical Land Use

Aquands are shallow depth and frequently waterlogged volcanic ash soils, presenting seasonal dynamics of water content in the soil profile. Land use change and management are expected to alter the Aquands biological activity due to their impact to water/air relationships as well as nutrient dynamics and greenhouse gases emissions. In southern Chile (41&#176;26&#8217;S;73&#176;07&#8217;W; 70 m a.s.l.), soil biological processes related to C- and N cycles, as well as greenhouse gas effluxes were assessed in relation to historical land use change and a drainage set in a naturalized grassland for animal husbandry. Disturbed soil samples were obtained in order to evaluate soil respiration, N mineral dynamics (NH4+ and NO3-), denitrification, nitrate reductase activity. Static-closed chambers were installed in the field to assess fluxes of CO2, N2O and CH4 from the soil surface at different seasons of the year with contrasting water table depths. Soil respiration responded to the historical land use change and draining effects. The aerobic and anaerobic biological processes related to soil nitrogen dynamics were less sensitive than respiration, and showed arbitrary effects according to the current use and management of the Aquand. Soil surface fluxes of greenhouse gases showed similar patterns, where CO2 emissions responded temporarily to land use, while N2O and CH4 did not respond conclusively. The content of soil organic carbon associated to the structural changes derived from land use change (e.g. fire clearance) and soil management (e.g. animal trampling) are plausible parameters to explain the variations of CO2 emissions from Aquand soils surface, while other elements such as microbial community and the ferrous wheel hypothesis, should be investigated in order to explain the biological responses and trace greenhouse gases emissions.

Stocking Rates

Oat yields and wool production of Merino wethers were measured at five stocking rates in five systems of land use in each of two years, 1971 and 1972, in north-east Victoria. Nominal stocking rates were 6.8, 8.6, 10.5, 12.4 and 14.2 sheep ha-1. The production at each stocking rate was compared in the following systems: 1, all pasture; 2, and 3. pasture grazed year long with oats grazed in winter and oat stubbles in summer on 15 per cent (system 2) or 30 per cent of the plot area (system 3) ; 4. and 5. pasture grazed throughout with oat stubbles grazed in summer but crops not grazed during the growing season and crops comprised either 15 per cent (system 4) or 30 per cent of the plot area (system 5). In 1971 the rainfall of 540 mm was sufficient to produce a harvestable oat crop and to maintain sheep on all plots without supplements. The mean oat yield of 2.04 � 0.01 t ha-1 for system 3 far exceeded that of the more heavily grazed crops in system 2 (1.44-0.05) or of ungrazed crops in systems 4 and 5 (1.44i-0.07). Clean wool production per head from each system was compared in terms of an 'average' stocking rate S which accounted for variation in grazing intensity throughout the year inherent in systems 2, 3, 4, 5. In 1971 clean wool production kg-1 declined with increase in average stocking rate in all systems but the mean of the four dual land use systems did not differ from the all pasture system (1). 1972 was a drought year with only 330 mm of rain, oat crops failed to produce grain and were grazed from October. The wool production of sheep on systems 2 to 5 was greater than that of sheep at equivalent average stocking rates on the all pasture system. Growing oats for grazing and grain in association with wool production would appear to be more profitable than wool production alone. Light grazing of oats in winter may increase oat yield but more information is needed in relation to seasonal variation and oat variety.
