  • Greenhouse Gases-California-Things to Know

    Here are some things to know about California Gov. Jerry Brown's new target for reducing carbon emissions that contribute to climate change. WHAT DO THE NUMBERS MEAN? Brown set a goal for the state to reduce emissions to 40 percent below what they were in 1990. Countries set that year as a benchmark for climate change when they signed on to the U.N. Kyoto Protocol, an ...

  • Performance evaluation of condensation–irrigation solar system under arid climate conditions

    Scarcity of water, major critical concern in arid areas, has led to the use of low–quality irrigation water in agriculture in most of arid climate areas. The quality of water used for agriculture has to be reduced to a sustainable level that is also adapted to the environment. This paper presents the performance of a pilot condensation irrigation (CI) solar system in Tunisia under arid ...

  • Seasonal changes in the performance of a catch crop for mitigating diffuse agricultural pollution

    An in situ technology for mitigating diffuse agricultural pollution using catch crops was developed for simultaneously preventing nitrate groundwater pollution, reducing nitrous oxide (N2O) gas emissions, and removing salts from the topsoil. Seasonal changes in the performance of a catch crop were investigated using lysimeters in a full-scale greenhouse experiment with 50 d ...

  • From Landfill to the Tomato Plant -- Purified Biogas Powers Greenhouse Operation

    In 2009, the Board of Waste Management for the Mauricie region of Quebec, Canada (RGMRM) found a biogas purification solution through an Eco-Tec Inc. system known as BgPur, which uses a patented, high efficiency gas-liquid contacting process, allowing H2S to be absorbed and the gas purified for reuse in power generation, cogeneration and heating applications. The aim was to purify the landfill ...

  • Fluorinated greenhouse gases 2011

    Greenhouse gases covered by the UNFCCC Kyoto Protocol include amongst others, three groups of fluorinated greenhouse gases (the so-called 'F-gases'): hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). These F-gases typically have very long lifetimes in the atmosphere and high global warming potentials (GWPs). The European Union Regulation (EC) No 842/2006 on ...

  • Fuel a small part of construction`s greenhouse impact

    The best way for Canadian construction to reduce its energy consumption will not necessarily be found in how it powers its work, says a leading energy research analyst. "The energy consumed in construction products is 35 to 40 per cent of the grand total of energy consumed in Canada. The ‘stuff’ that construction needs to make 'stuff is energy intensive," said John Nyboer, executive ...

  • GHG-Framed mitigation actions by Developing Countries

    International negotiations on climate change have recognized the importance of enhanced national action on mitigation, and of finance, technology, and capacity-building support to developing countries. Since 2009, a growing number of developed and developing countries have pledged mitigation targets and actions, and developed countries have committed to provide financing to developing countries, ...

  • Dryland performance of sweet sorghum and grain crops for biofuel in Nebraska

    Sweet sorghum [SS; Sorghum bicolor (L.) Moench] is a potential biofuel crop for the Great Plains. Sweet sorghum was compared with corn [Zea mays (L.)] and grain sorghum for potential ethanol yield, energy use efficiency, and greenhouse gas (GHG) emissions at seven dryland site-years in Nebraska. Seasonal rainfall ranged from approximately 340 to 660 mm. Soils were deep with medium texture at all ...

  • Evaluation of nitrogen sources and application methods for nitrogen-rich reference plot establishment in corn

    Five different N sources were compared with null N treatment to evaluate their performance for N-rich reference plot establishment in corn (Zea mays L.). The sources, including calcium ammonium nitrate (CAN), urea ammonium nitrate (UAN), polymer-coated urea (PCU) and environmentally smart nitrogen (ESN) in 2007 and 2008, and urea (URE), were broadcast or in-soil banded at the rate of 225 kg N ...
