TRINITY RIVER BASIN,TEXAS1

ABSTRACT: In 1991 the Trinity River Basin National Water-Quality Assessment (NAWQA) was among the first 20 study units to begin investigations under full-scale program implementation. The study-unit investigations will include assessments of surface-water and ground-water quality. Initial efforts have focused on identifying water-quality issues in the basin and on the environmental factors underlying those issues. The environmental setting consists of both physical and cultural factors. Physical characteristics described include climate, geology soils, vegetation, physiography, and hydrology. Cultural characteristics discussed include population distribution, land use and land cover, agricultural practices, water use, and reservoir operations. Major water-quality categories are identified and some of the implications of the environmental factors for water quality are presented.

不同地质背景水库区夏季水-气界面温室气体交换通量研究

岩溶水库水化学特征受碳酸盐岩溶蚀风化产物所控制,形成"富钙偏碱高溶解无机碳"的特殊环境,其水-气界面温室气体交换特征、过程及影响因素与其他非岩溶水库存在较大差异.为揭示不同地质背景控制下典型水库水-气界面温室气体交换的特征及控制机制,选取广西三座不同地质背景的水库[大龙洞水库(岩溶水库)、五里峡水库(半岩溶水库)、思安江水库(非岩溶水库)],同时运用静态箱法(FC)和模型计算法(TBL)对其水-气界面温室气体(CO2、CH4)交换通量进行比较研究.结果表明:1两种方法获得的结果均显示,大龙洞水库库区和出库水体均为大气CO2、CH4的源;五里峡水库库区总体上为大气CO2的汇、大气CH4的源,其出库水体均为大气CO2、CH4的源;思安江水库库区均为大气CO2的汇、大气CH4的源.2无论是岩溶水库还是非岩溶水库,其出库水体温室气体排放量远大于库区,如何控制水库出库水体的CO2、CH4释放问题值得关注.3在没有大量淹没土壤有机质和植物的情况下,由岩溶地下水补给的水库水-气界面CH4交换通量与其他半岩溶水库和非岩溶水库差别较小,但由于富含DIC水体的输入及受水库热分层的影响,其CO2交换通量要明显高于其他非岩溶水补给的水库.

One Hundred Questions of Importance to the Conservation of Global Biological Diversity

Abstract:  We identified 100 scientific questions that, if answered, would have the greatest impact on conservation practice and policy. Representatives from 21 international organizations, regional sections and working groups of the Society for Conservation Biology, and 12 academics, from all continents except Antarctica, compiled 2291 questions of relevance to conservation of biological diversity worldwide. The questions were gathered from 761 individuals through workshops, email requests, and discussions. Voting by email to short-list questions, followed by a 2-day workshop, was used to derive the final list of 100 questions. Most of the final questions were derived through a process of modification and combination as the workshop progressed. The questions are divided into 12 sections: ecosystem functions and services, climate change, technological change, protected areas, ecosystem management and restoration, terrestrial ecosystems, marine ecosystems, freshwater ecosystems, species management, organizational systems and processes, societal context and change, and impacts of conservation interventions. We anticipate that these questions will help identify new directions for researchers and assist funders in directing funds.     

A national and local media perspective on responsibility for and solutions to storm-related power outages in the northeastern United States

Major storms in the northeastern United States in 2011 and 2012 caused widespread power outages, bringing attention to the vulnerability of utility infrastructure as a result of extreme weather and environmental change. Media coverage of such focusing events provides context for and can affect government and public response. Our objective was to analyze gatekeeping, agenda setting, and framing in the New York Times (NYT) and local newspapers covering power outages related to large storm events in 2011 and 2012 (Tropical Storm Irene, October snowstorm, Hurricane Sandy). Government and utility officials focused on structural solutions to mitigate future storm impacts, whereas residents and businesses targeted individual actions. NYT interviews included residents more frequently than local newspapers, influencing coverage of impacts and solutions. Geographic differences between NYT and local newspapers’ foci may relate to coverage of solutions to and responsibility for outages. Our findings demonstrate the importance of collective action toward shared solutions.     

Assessing sustainability: An assessment framework to evaluate Agenda 21 actions at the local level

In Switzerland, communities are encouraged to define and to report on local Agenda 21. This paper presents an analysis framework to help local communities set sustainable development priorities and to follow through with appropriate actions. Four Swiss communities, from the French-speaking part of Switzerland, actively follow the project: Lausanne (114 304 citizens), Vevey (15 364 citizens), Mannens-Grandsivaz (505 citizens) and Essertines/Yverdon (666 citizens). The analysis framework developed is constituted of four interdependent fields: the societal characteristics, the individual or collective behaviours, the end objectives or sustainability impacts and the inhabitant's perception of these three fields. The link between society and behaviour can be studied through sociological analyses. The link between behaviour and environmental impact can be established thanks to Life Cycle analysis and Input/Output analyses. At each level, sustainable development indicators can be defined. As an application of the framework, the citizen energy consumption has been studied and expressed in energy slaves (= 3150 MJ/Year). A Swiss citizen needs altogether 69 slaves, 20 for his private consumption of goods and services, 19 for housing, 11 for transport, I1 for food and 8 for his consumption of public goods. If one fifth of the inhabitants of Lausanne, wanting to live closer to nature, actually moved out of town, the region would need 10 436 more slaves for 3500 persons happily living in the countryside.
