The intensive land use invariably has several negative effects on the environment and crop production if conservative practices are not adopted. Reduction in soil organic matter (SOM) quantity means gas emission (mainly CO2, CH4, N2O) to the atmosphere and increased global warming. Soil sustainability is also affected, since remaining SOM quality changes. Alterations can be verified, for example, by soil desegregation and changes in structure. The consequences are erosion, reduction in nutrient availability for the plants and lower water retention capacity. These and other factors reflect negatively on crop productivity and sustainability of the soil-plant-atmosphere system. Conversely, adoption of "best management practices", such as conservation tillage, can partly reverse the process - they are aimed at increasing the input of organic matter to the soil and/or decreasing the rates at which soil organic matter decomposes.

• Bioenergy and sustainable development (2007, background): “practices also have an effect on soil organic matter—conversion of native vegetation to cropland under intensive tilling practices, for example, contributes to reduction in soil organic matter through disruption of soil aggregates, increased microbial activity, and erosion (136).”
• ANTIFUNGAL COMPOUND PRODUCED BY THE CASSAVA ENDOPHYTE Bacillus pumilus MAIIIM4A (2009, background): “In Brazil, the main activity that contributes to greenhouse gas emissions is the land use management and conversion of soils in agriculture (Cerri et al., 2007; Fearnside, 2006).”
• Impacts of climate change on plant diseases—opinions and trends (2012, background): “The main causes of this global [CO2] increase are fossil fuel burning and land-use changes (mainly deforestation) (Cerri et al. 2007; Paterson and Lima 2010).”
• Diseases in tropical and plantation crops as affected by climate changes: current knowledge and perspectives (2011, background): “Crop simulation models, driven by future climate scenarios from global circulation models, suggest that the reduction in agricultural production would be more severe in tropical regions, where there is still a shortage of food production (Cerri et al., 2007).”
