Non-CO2 Greenhouse Gases: Why and How to Control?
The background This volume contains the proceedings of the first International symposium on "Non-C0 Greenhouse Gases: Why and How to 2 Control?" held in Maastricht, The Netherlands from 13-15 Decem ber 1993. Of the known greenhouse gases, political attention to date has been primarily focused on carbon dioxide (C0 ) and the 2 CFCs - the latter because of their interaction with stratospheric ozone. The other greenhouse gases, notably methane (CH ), nitrous 4 oxide (N 0), HCFCs, HFCs and tropospheric ozone and its precur 2 sors nitrogen oxides (NO), carbon monoxide (CO) and volatile organic compounds (VOCs), may appear collectively to be of equal importance for global warming but have attracte...
Nitrogen, the Confer-N-s
The First International Nitrogen Conference provided an opportunity for researchers and decision-makers to exchange information on environmental pollution by nitrogen compounds on three scales: global, continental/regional and local. The main topics were air, ground water and surface water pollution; emission sources, atmospheric chemistry, deposition processes and effects; disturbance of nitrogen cycles, critical loads and levels; assessments, policy development and evaluation; target groups and abatement techniques; and new approaches leading to an integrated abatement strategy.The peer-reviewed papers from the Conference presented in this volume will provide readers with a comprehensive review of the transport, deposition and impact on ecosystems of nitrogen.
Advances in Agronomy
Volume 73 contains 4 reviews on contemporary and important topics in the agronomic sciences. In Chapter 1, "Interactions among Root-Inhabiting Fungi and Their Implications for Biological Control of Root Pathogens," fungi are defined, their distribution and abundance are discussed, and their role in agroecosystems is present. Chapter 2, "Dwarfing Genes in Plant Improvement," discusses advances in the role of dwarfing genes in plant improvement. Emphasis is placed on breeding and genetic aspects. Chapter 3, "A Review of the Effect of N Fertilizer Type on Gaseous Emissions," covers a topic that is of great environmental interest — the effect of nitrogen fertilizers on gaseous emissions. Chapter 4, "Rhizobia in the Field," is a comprehensive review of rhizobia including diversity, systematics, natural populations, and field introduction of rhizobia.
Improving Characterization of Anthropogenic Methane Emissions in the United States
Understanding, quantifying, and tracking atmospheric methane and emissions is essential for addressing concerns and informing decisions that affect the climate, economy, and human health and safety. Atmospheric methane is a potent greenhouse gas (GHG) that contributes to global warming. While carbon dioxide is by far the dominant cause of the rise in global average temperatures, methane also plays a significant role because it absorbs more energy per unit mass than carbon dioxide does, giving it a disproportionately large effect on global radiative forcing. In addition to contributing to climate change, methane also affects human health as a precursor to ozone pollution in the lower atmosphere. Improving Characterization of Anthropogenic Methane Emissions in the United States summarizes the current state of understanding of methane emissions sources and the measurement approaches and evaluates opportunities for methodological and inventory development improvements. This report will inform future research agendas of various U.S. agencies, including NOAA, the EPA, the DOE, NASA, the U.S. Department of Agriculture (USDA), and the National Science Foundation (NSF).

Non-CO2 Greenhouse Gases: Scientific Understanding, Control and Implementation
In the climate change discussion, non-CO2 greenhouse gases (NCGGs) received official political recognition for the first time in 1997, when agreement was reached on the Kyoto Protocol. As a result methane, nitrous oxide, HFCs, PFCs and SF6 now provide attractive options for detailing the national targets for the reduction of greenhouse gas emissions meant to control climate change. This book is the second volume in this area and addresses three main topics. Firstly, it documents progress with respect to our knowledge of the sources and sinks of NCGGs. Information on this subject is essential in order to reduce the uncertainties in national emissions inventories which serve as the reference v...
