Abstract: Future rice systems will need to produce more grain while minimizing the environmental impact. A key question is how to orient agricultural research & development (R&D) programs at national to global scales to maximize the return on investment. Here we assess yield gap and resource-use efficiency (including water, pesticides, nitrogen, labor, and energy) across 32 rice cropping systems, together accounting for 88% of global rice production. We show that achieving high yields and high resource-use efficiencies are not conflicting goals. Most cropping systems have room for increasing yield, resource-use efficiency, or both. In aggregate, current total rice production of these systems can be increased by 36%, and excess nitrogen almost eliminated, by focusing on a relatively small number of cropping systems with large yield gaps and/or poor resource-use efficiencies. This study provides essential strategic insight for prioritizing national and global agricultural R&D investments to ensure adequate rice supply while minimizing negative environmental impact in coming decades. |

Resumo: A madeira Eucalyptus globulus é uma importante matéria-prima para produção de polpa celulósica kraft. O objetivo deste trabalho foi avaliar diferentes materiais genéticos de E. globulus em termos de propriedades da madeira e polpa celulósica. Os resultados mostram que os valores de densidade básica podem ser considerados normais para madeiras destinadas à produção de polpa celulósica; as procedências com as maiores densidades básicas são originadas do sul do estado de Victoria; as dimensões de fibras indicam que todos os materiais avaliados podem ser utilizados para produção de polpa celulósica kraft; o teor de holocelulose variou de 69 a 72%; os maiores rendimentos depurados foram obtidos para os materiais do sul do estado de Victoria.
Abstract: Eucalyptus globulus is an important raw-material for kraft pulping and has a wide geographical distribution. The objective of this paper was to evaluate E. globulus origins in terms of their wood and pulp properties. The results showed that wood density values for the origins are within the values considered advisable for kraft pulp production; origins with the highest wood density were from the south of Victoria state; fiber dimensions indexes obtained in this study allow us to infer that all origins are suitable for paper production; holocellulose content varied from 69 to 72%; the highest screened yield values correspond to the origins from south Victoria. |
