  • Assessing the promotion of urine-diverting dry toilets through school-based demonstration facilities in Kalisizo, Uganda

    Urine-diverting dry toilets (UDDTs) are designed to recover nutrients and organic matter from human excreta for agricultural reuse. Their wider implementation could help address problems in areas where water scarcity limits coverage of sanitation systems and declining soil fertility jeopardizes nutritional security. Demonstration facilities can improve stakeholders’ views of UDDTs; however, it ...

  • Biopesticides Examined for Role in Field Production

    Biopesticides deserve respect. Once derided as snake oil, today’s products have proven benefits in suppressing pest organisms. Whether they activate plant defenses, parasitize or inhibit pathogen growth or make the environment less favourable to disease, they can play an integral role in crop protection. While the greenhouse sector first excelled at incorporating biopesticides in controlled ...

  • Pesticides in foods

    The use of pesticides in foods is a concern - especially as some of these substances build up in food and pass into the human body. A pesticide is a substance used in agriculture mainly for repelling, eliminating, reducing, etc insects or microorganisms that might harm the crops. There are numerous scientific studies that demonstrate the problems that these substances can cause within the body - ...

  • A long‐term assessment of pesticide mixture effects on aquatic invertebrate communities

    To understand the potential effects of pesticide mixtures on aquatic ecosystems, studies that incorporate increased ecological relevance are crucial. Using outdoor mesocosms, the authors examined long‐term effects on aquatic invertebrate communities of tertiary mixtures of commonly used pesticides: 2 pyrethroids (permethrin, λ‐cyhalothrin) and an organophosphate (chlorpyrifos). Application ...

  • The complex nature of GMOs calls for a new conversation

    An honest discussion of genetically modified organisms must move beyond narrow concepts of human health to the wider social and environmental impacts of engineered crops. The GMO debate is one from which I’ve kept a purposeful distance. For one thing, it’s an issue that has already garnered more than its fair share of attention. For another, when you consider that many ...

  • The DNA of the U.S. Regulatory System: Are We Getting It Right For Synthetic Biology?

    U.S. regulatory oversight of synthetic biology across the board needs to be modernized to reflect and address the promising technologies routinely entering the market. From a statutory perspective, the pertinent laws appear sufficiently broad to empower federal agencies to address potential risks and promote the potential benefits of synthetic biology. The regulatory infrastructure, however, is ...

  • Can bats reduce nut farmers’ pesticide use?

    Ecologist Katherine Ingram is on a quest to quantify the economic value of insect-eating bats in walnut groves. For the past three years, Katherine Ingram has had a most unusual summer job: catching bats and studying their droppings to see what they eat. A doctoral student in ecology at the University of California, Davis, Ingram is exploring the role bats can play as winged ...

  • Ninth Circuit Vacates EPA’s Unconditional Registration for the Neonicotinoid Pesticide Sulfoxaflor Based on Hazard to Bees

    In an opinion issued on September 10, 2015, the U.S. Court of Appeals for the Ninth Circuit vacated the U.S. Environmental Protection Agency’s (EPA) unconditional registration for the pesticide sulfoxaflor and remanded the matter to EPA to obtain further studies and data regarding the effects of sulfoxaflor on bees and bee colonies. Sulfoxaflor is a new insecticide in the class of ...

  • NGOs Challenge Nanosilva’s Conditional Registration

    On July 27, 2015, two petitions for review of the U.S. Environmental Protection Agency’s (EPA) second conditional registration of a nanosilver pesticide product were filed in the U.S. Court of Appeals for the Ninth Circuit. The Natural Resources Defense Council (NRDC) filed a petition (Case Number 15-72308), as well as the Center for Food Safety (CFS) and International Center for Technology ...

  • Biopesticide‐induced behavioral and morphological alterations in the stingless bee Melipona quadrifasciata

    Due to their natural origin, biopesticides are assumed to be less harmful to beneficial insects, including bees, and therefore their use has been widely encouraged for crop protection. However, there is little evidence to support this ingrained notion of the biopesticide safety to pollinators. As larval exposure is still largely unexplored in ecotoxicology and risk assessment on bees, we ...

  • A win for farmers and the environment

    Is it possible to reduce pesticide use without compromising crop yields? Yes — and then some, according to a new study published in the journal Insects. Researchers at the University of Essex in the United Kingdom measured pesticide use and crop yield at 85 project sites in 24 Asian and African countries practicing integrated pest management ...

  • Here today, gone tomorrow: Short‐term retention of pesticide‐induced tolerance in amphibians

    Pesticide use has led to the ubiquitous contamination of natural habitats, which has inadvertently increased pesticide tolerance in target and non‐target species. Historically, increased pesticide tolerance has been attributed to natural selection on tolerance among individuals of affected populations. Recent research, however, has discovered that pesticide tolerance can be increased through ...

  • Evaluation model for cultural heritage in spatial planning

    The article describes the evaluation model for cultural heritage in spatial planning, created in the shifting perspective from a static-contemplative to a dynamic-planning understanding of the heritage. The shift is manifested in the creation of the model which allows analysis, diagnosis, definition of strategies for spatial heritage (registered and under the consideration for protection) and ...

  • The effects of the amphibian chytrid fungus exposure to American toads in the presence of an insecticide

    Abiotic factors like pesticides may alter the impact of a pathogen on hosts, which could have implications for host‐pathogen interactions and may explain variation in disease outbreaks in nature. In this laboratory experiment, we exposed American toad (Anaxyrus americanus) metamorphs to the amphibian chytrid fungal pathogen, Batrachochytrium dendrobatidis (Bd), and environmentally relevant ...
