Bioethanol and other sugarcane by-products, such as the bagasse, are responsible for approximately 12% of Brazil?s total energy generation. This crop is expanding in the Central-Western Region of Brazil, within the Brazilian savannah biome (Cerrado). It is strongly associated with the use of mineral and/or organic fertilizers and irrigation practices due to drought period during winter. However, higher soil moisture content (due to rain or irrigation) and nitrogen (N) application increase nitrous oxide (N2O) emission, which is one of the main greenhouse gases from the agricultural sector. This study aimed to evaluate soil N2O fluxes in sugarcane under field conditions with contrasting water regimes in the Cerrado region of Brazil. Due to watering regimes, based on different crop evapotranspiration demand, it was possible to establish adequate water-use efficiency technologies. Increases in watering regimes did not increase N2O emissions compared to ??rescue irrigation??, commonly used by farmers in the region. However, higher yields were obtained from the higher watering regime (T75%) compared to the farmers? common practice. |

National plant protection and quarantine authorities have the mandate for
protecting the resources of their countries from invasive pests entering from
outside their borders. The import of fruits is one among other potential carriers
of unwanted pests such as people, commodities and conveyances. While
prohibiting the import of fruits may be an effective method of excluding foreign
pests, it runs the risk of being perceived as a trade barrier unless justified by a
risk analysis. Risk analysis is the process of evaluating biological or other scientific and
economic evidence to determine whether a pest should be regulated and the
strength of any phytosanitary measures to be taken against it. Risk analysis
provides the best means of ensuring that chief technical officers fulfill their legal
obligations and international obligations when developing and implementing
import health standards. |
