Impact of climate changes on potential sugarcane yield in Pernambuco,northeastern region of Brazil

Sugarcane is a typical culture of hot and humid climate and therefore is well adapted to the climate in many regions of Brazil. However, there may be yield reductions in the Northeastern region of Brazil due to possible future reductions in rainfall levels. The aim of this study was to simulate, using the Century 4.5 model, the impact of climate changes on potential sugarcane yield in Goiana and Itambé, Zona da Mata of Pernambuco. The Century 4.5 model was booted with soil and climate data from 1950 to 2012. Data on total soil carbon, soil texture (sand, silt and clay contents), pH, soil density and soc stocks were obtained from previous studies. The climate scenario used was the average emissions SRES A1B, designed by Eta/CPTEC model for periods 2014–2040, 2041–2070 and 2071–2100, which is composed of LOW member (low emissions) and HIGH member (high emissions). According to the results obtained by A1B scenario, the potential yield can be reduced in the near future (2014–2040). The high temperatures in northeastern Brazil will increase the evapotranspiration rates, reducing the amount of water available in the soil, making the planting of sugarcane increasingly difficult, which tend to be strongly reduced in drier areas, such as cities located in the western portion of the Zona da Mata region, northern state of Pernambuco, Brazil.     

二十一世纪染色技术展望(I)

文章从新型纤维的出现,纤维改性的进步,新型和功能染料及助剂的应用,以及染色新工艺的发展等方面,系统地展望了二十一世纪染色新技术。并认为二十一世纪的染色产品必然是高新性能、功能性、高附加值和环保型的“绿色”产品,其染色是高科技应用的系统工程,其中一些染色新技术目前已经得到了应用或正在开发应用,另一些技术不久可能开发应用,文章指出了它们的应用潜力和前景。最后还综合介绍了“绿色”染色工程,指出它是一个涉及纤维和纺织品的原坯、染化料、染色工艺以及能源和设备各方面的系统工程。

新海派住宅风格

以“海纳百川、刻意创新、没有历史的沉重感”的新海派住宅风格的特征应该是：人性化的城市聚居区,舒适安全便捷的集聚居住空间,少装饰,没有沉重的历史负担,表现在对大自然的向往,轻松愉快的居住氛围。注重室内外空间的实用、方便和经济性,讲究个性和建筑细部、多元化的建筑形象。对生态环境和大自然的追求,对住宅科技含量的追求,是新海派住宅风格的内涵和推动力。     

From Marrakech through The Hague to Kyoto: Has the Global Debate on Water Reached a Dead End?

Abstract

Although the first World Water Forum was held in 1997, realization by the world community of the vast array of problems facing the water sector dates back to the seventies. Indeed, the Mar del Plata Water Conference that was held in 1977 can be considered the first world water forum. Since that time, a series of international conferences, including the three world water forums that were held in Marrakech, The Hague, and Kyoto, have been organized to discuss the existing and emerging water problems. Such conferences and forums have debated the major issues regarding management and development of water resources, and have adopted a number of resolutions, declarations, and action plans. The debate on many of those issues has sharpened in recent years and the resolutions, declarations, and action plans have multiplied. This article discusses the basic elements of the debate and the areas of differences between the various groups, and assesses the efficacy and impact of the resolutions, declarations, and action plans adopted at those conferences.

This is the first of a two-part article, the second of which will be published in the next issue of this Journal.     

十九世纪珠江流域文化景观特征 ——基于西方文献的分析

自古以来，河流及其流域构成了一些最 具活力和最复杂的景观。河流维系着人类社会， 人类社会则以多种方式利用河流，从而产生璀璨 的流域文明。广州作为西方人眼中的一座 “神 奇”城市，两千年来一直是中国最重要的海上门 户，现如今，我们可以从外国商人、船长、旅行 者、传教士等游记、报告或图像记录中获得大量 关于珠江流域文化景观的详细描述。本文尝试 将珠江流域的河流系统及其相关的文化景观作 为人类经验的重要组成部分进行研究，透过西 方人的视野，去分析其对珠江流域及其文化景 观的所见所闻，并深入挖掘珠江流域文化景观 的构成与特征，从而归纳出珠江流域文化景观 中的人水共生关系，为珠江流域文化遗产保护 研究提供了全新的视角与思路。
