  • Evaluation of greenhouse gas emissions and design of mitigation options: a whole farm approach based on farm management data and mechanistic models

    Agricultural activities are important sources of nitrous oxide (N22O), methane (CH4) and carbon dioxide (CO2). They contribute approximately 10% of the total emitted greenhouse gases (GhG) in the European Union. We search for evaluating GhG emissions at the farm level and designing mitigation options. As emissions occur at many stages within the farm operation, it is crucial to ...

  • Motor transport, greenhouse gases and economic instruments

    Motorised transport is the generator of several forms of negative externality including the uncompensated emissions of greenhouse (global warming) gases. This paper looks at some of the underlying economic issues pertaining to policy-making designed to limit the extent of these externalities. It sets out the basic nature of the problem and outlines our knowledge of the link between the physical ...

  • 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 ...

  • Case study - 12 Panel Solar PV Greenhouse

    Cambridge System kWp: 1.08 Area: 16.32 m2 Inverter: Soladin 600 Modules Used: PS-C Transparent Polysolar supplied and installed the world's first solar PV greenhouse for a long standing customer in Cambridge.

  • GreenWare`s Greenhouse Gas Performance Software.

    In December 1997, member countries of the United Nations reached agreement to reduce their total greenhouse gas emissions under the Kyoto Protocol. By 2005, all member countries will have to report on their progress. Such international action reflects the immediate need to tackle the issue of greenhouse gas emissions and their impact on climate change. As the world looks to the new millennium, ...


  • Separating the wheat from the chaff: Regulating greenhouse gases in a climate of uncertainty

    This article discusses the difficulty of regulating greenhouse gas emissions in the face of uncertainty, particularly with respect to the level of reductions needed in the post-2012 era to avoid dangerous climate change. There are also a number of regulatory options available, including carbon taxes, emissions trading, regulations and standards, and fiscal measures. Yet emissions trading has ...

  • Modelling water requirements of greenhouse spinach for irrigation management purposes

    Estimating water requirements of plants cultivated in greenhouse environments is crucial, both for the design of greenhouse irrigation systems and the improvement of irrigation scheduling. Spinach is one of the main vegetables sold as ‘ready-to-eat’ bagged produce; it is very sensitive to water stress and thus requires accurate irrigation. In this work, a water balance model simulating the ...

  • New EPA ruling deems greenhouse gases (GHGs) harmful to humans

    Greenhouse Gases (GHGs) will be categorized as a pollutant following the US Supreme Court's landmark notice approving the Environmental Protection Agency’s (EPA) ruling. The gases harm the environment as they have proved to increase heat trapping chemicals in the atmosphere. These chemicals, commonly taking the form of refrigerant gases, originate from a variety of systems, including ...

  • Fertilizer application timing influences greenhouse gas fluxes over a growing season

    Microbial production and consumption of greenhouse gases (GHG) is influenced by temperature and nutrients, especially during the first few weeks after agricultural fertilization. The effect of fertilization on GHG fluxes should occur during and shortly after application, yet data indicating how application timing affects both GHG fluxes and crop yields during a growing season are lacking. We ...

  • Comparison of date-palm wastes and perlite as culture substrates on growing indices in greenhouse cucumber

    Abstract Different substrates have several materials which could have direct and/or indirect effects on plant growth and development. Therefore selecting the best substrate between the ...

  • Safeguarding forests and People: A framework for designing a national system to implement REDD+ safeguards

    Background Around the world, members of governments, civil society, and the private sector are grappling with how to design and implement initiatives that reduce greenhouse gas emissions by slowing, halting, and reversing forest loss. These efforts have been spurred at least in part by the agreements onlong-term cooperative action (LCA) that Parties to the United Nations Framework ...

  • 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 climate ...
