  • 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 ...

  • LCA and tomato production in Mediterranean greenhouses

    LCA is used to analyse and evaluate the environmental impact associated with the process of greenhouse cultivation of a tomato crop. Tomato production in kg is selected as a functional unit. Three different tomato production processes were compared: soil cultivation and open and closed hydroponic systems. Three different waste management scenarios were also analysed. The most significant negative ...

  • 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, ...


  • 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 ...

  • Towards theoretical multiplicity for the governance of transitions: the energy-producing greenhouse case

    Transition management has become an important topic in scientific research on sustainable development over the last decade. A recurring question is whether, and if so how, transitions towards sustainability can be governed. In this paper we address this question by theoretically comparing transition management theory with a number of related theories on governing societal change, such as ...

  • Reporting of greenhouse gases (GHGs) to be mandated for top 13,000 facilities

    The newly formed Obama administration has listed greenhouse gas (GHG) tracking and reporting as a major goal, with the objective of protecting the future of the environment by reducing today's carbon footprint. If no action were taken, the makeup of the earth would significantly altered. Future actions will establish a market drive carbon cap and trade program to drive GHG emissions ...

  • 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 ...

  • 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 ...

  • Commission Calls for New Policies as EU Greenhouse Gases Rise Again

    EU greenhouse gas emissions rose for the second successive year in 2001, raising concerns over progress towards targets under the Kyoto Protocol. The European Commission has responded with a call for 'additional measures' to cut emissions from industry, transport and products. Under the Kyoto Protocol, the EU signed up to reduce its greenhouse gas emissions to 8% below the 1990 level by 2008-12. ...

  • Chicago Council lists three-decade changes in greenhouse gases and average temperature

    In 2011, we wrote a column, “Global warming is happening: How should farmers respond?” (http://agpolicy.org/weekcol/549.html). In that column we began by saying, “There was a time when one could legitimately argue that there was a lack of scientific agreement over the issue of the role of humans in global warming and even whether we were in a ...

  • Energy use and greenhouse gas emissions and related improvement options of the broiler chicken meat supply chain

    Energy consumption and the climate–change impact (i.e., carbon footprint) of a typical Finnish broiler chicken fillet product were studied using a supply–chain integrated life cycle assessment method. All essential production stages from parent stock and production of farming inputs to product distribution and sales in retail stores were included in the assessment. The results of the ...

  • Measurement and modelling of the water requirement of some greenhouse crops with artificial neural networks and genetic algorithm

    Crop evapotranspiration is the most important parameter for management of irrigation systems in greenhouses. This study was conducted to determine the evapotranspiration of cucumber, tomato and peppers, using micro–lysimeter during seven months in a greenhouse located in central region of Iran. Reference evapotranspiration estimated using drainage lysimeters and the water balance of soil ...

  • Can pulse crops play a role in mitigating greenhouse gases from North American agriculture?

    The atmospheric buildup of greenhouse gases (GHGs) is a serious environmental issue. Globally, agricultural activities are an important source of anthropogenic GHGs, contributing 20% of the annual atmospheric increase. Management choices largely determine if agricultural soils will be a source, a sink, or will be neutral with respect to GHG net flux. The proportion of agricultural land that is ...

  • Environmental technology and management in Dutch horticulture

    An important strategy for a firm to improve its environmental performance is adoption of environmentally friendly technology. However, technology switching is often hampered by high investments costs. If the environmental friendly technology would also lead to an increase in technical efficiency firms might more easily decide to switch technology. However, the empirical evidence for improved ...

  • Cropland management techniques for carbon storage

    The Kyoto protocol of 1997 recognises cropland management as a carbon sequestration strategy which may help to mitigate climate change. Under the protocol, ratified by the EU in 2002, member states are obliged to reduce the sum of their emissions of greenhouse gases to 5 per cent below their 1990 levels. Appropriate cropland management may help member countries meet the overall EU emissions ...

  • Towards climate-responsible peatlands management

    Peatlands are lands with a naturally accumulated peat layer at their surface. They are found all over the world and come in many forms, display many different characteristics and are used in many different ways. Even though peatlands extend over a relatively small portion of the earth’s land surface, they hold a large pool of carbon. There is no universal definition of peatlands. For the ...
