  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Soil management practices for sustainable agro-ecosystems

    A doubling of the global food demand projected for the next 50 years poses a huge challenge for the sustainability of both food production and global and local environments. Today’s agricultural technologies may be increasing productivity to meet world food demand, but they may also be threatening agricultural ecosystems. For the global environment, agricultural systems provide both sources and ...

  • Large-scale irrigation - Understanding energy-water-food connections

    Original story at MIT News An MIT team is providing new understanding of the growing interconnections among three critical resources: energy, water and food. The work focuses on Pakistan's Indus Basin, where irrigation water is increasingly pumped from underground, a practice that is intensifying a preexisting shortage of energy. Using new and ...

  • Composting and local food merge st urban garden

    Growing Power (GP), a nonprofit urban garden and training center in Milwaukee, Wisconsin, provides affordable produce to neighborhoods without access to fresh food, and processes a variety of organic wastes through composting and anaerobic digestion. Located on a two-acre lot on Milwaukee's north side, the six greenhouses and several hoop houses include raised beds for herbs and greens, ...

  • Agroforestry Mitigates Climate Change

    Climate changes, as one of the biggest threats to a global food security, highly influence natural resources that are essential for crop production. Farming is not only affected by the impact of climate changes, but it’s also a significant contributor to global greenhouse gas emissions. Intensive farm practices that include both farm production and change of land use, directly affect the ...

  • Irrigation of eucalyptus plantation using treated bleached kraft pulp mill effluent

    The use of treated pulp mill effluent on eucalyptus plantation appears to be an attractive option for plant nutrition and water supply. It also constitutes a supplementary treatment process and a final disposal option for the mill effluent. This study aimed at the investigation and evaluation of the effects of bleached kraft pulp mill treated effluent on three typical Brazilian soils used for ...

  • Strategies to mitigate diffuse phosphorus pollution during rewetting of fen peat soils

    The cultivation of fen peat soils (Eutric Histosols) for agricultural purposes, started in Europe about 250 years ago, resulting in decreased soil fertility, increased oxidation of peat and corresponding greenhouse gas fluxes to the atmosphere, nutrient transfer to aquatic ecosystems and losses in total area of the former native wetlands. To prevent these negative environmental effects set-aside ...

  • The role of urban forest in the protection of human environmental health in geographically-prone unpredictable hostile weather conditions

    INTRODUCTION The structure of urban forest Few people know how many or what kind of trees are found in urban areas, or the effect these trees have on a city’s environment and the health and well being of its inhabitants. In order to understand the urban forest structure and its function in environmental improvement 5 major landscape elements, i.e., building and hard pavement surface, water, ...

  • Have Your Steak and Eat It, Too

    In our recent feature, “Has Meat Met Its Match?,” writer Rowan Jacobsen explores ways people can (now and possibly in the future) reduce the environmental and food security impacts of their diets, including entomophagy (bug-eating), synthetic meat and vegetarian substitutes. If none of those fits your needs, there are plenty of other ways ...
