  • Rational application of chemicals in response to oil spills may reduce environmental damage

    Oil spills, for example those due to tanker collisions and groundings or platform accidents, can have huge adverse impacts on marine systems. The impact of an oil spill at sea depends on a number of factors, such as spill volume, type of oil spilled, weather conditions, and proximity to environmentally, economically, or socially sensitive areas. Oil spilled at sea threatens marine organisms, ...

  • Use of molecular markers for early warning detection of harmful algal blooms

    Harmful Algal Blooms (HABs) are a biological hazard for, and can also result from, aquaculture. To minimise economic and environmental impacts, an early warning detection system is needed. In this paper, two most commonly used molecular techniques are introduced with applications and examples involving work on the putatively toxic dinoflagellate Pfiesteria piscicida. Unlike previous reviews ...

  • Marine and coastal environment

    Although not always immediately apparent, our wellbeing as humans is affected by the environmental state of our seas, because many aspects of our lives benefit from the goods and services provided by well-functioning marine and coastal ecosystems. These ecosystem services offer a multitude of opportunities to provide an income for people for instance through production of fish and shellfish for ...

  • Re-oligotrophication as a challenge for tropical reservoir management with reference to Itaparica Reservoir, São Francisco, Brazil

    The process of reservoir eutrophication has been recognised as a central problem in tropical reservoir environmental quality. Effects of eutrophication are complex interactions involving a decrease in water quality, especially loss of aquatic biodiversity, occurrence of undesired species such as cyanobacteria with its cyanotoxins, mass development of macrophytes such as Egeria densa with its ...

  • Water quality in the Arosa Bay

    Background One of the great impediments to further development of shellfish aquaculture in the north-west region of Spain isa perception that industry expansion and tourism could have negative environmental effects on the coastal waters. Especially the bay around Villagarcia de Arosa is very famous because of its excellent areas for shellfish farming. The government of Spain is ...

  • Valuing Plastic – The Case for Business Action

    Concern is growing over the threat that widespread plastic waste poses to marine life, with conservative estimates of the overall financial damage of plastics to marine ecosystems standing at US$13 billion each year, according to two reports released last week at the first United Nations Environment Assembly. The eleventh edition of the United Nations Environment Programme (UNEP) Year Book looks ...

  • Coastal zones: achieving sustainable management

    Coastal zones are the link between land and the sea and are unique areas, highly diverse in species, habitats and ecosystems. They are environmentally sensitive and economically valuable, with ecosystems rich in biodiversity also providing benefits such as protection from the elements, food and opportunities for the generation of renewable energy. They are also extremely important to human ...

  • Ultrasound technology in water treatment: Algae control and reduction of biofilm formation

    Recent research projects have underlined the potential of ultrasound as a chemical free treatment in water-related applications. This article reviews the use of ultrasound produced by the LG Sonic technology, with a focus on wastewater, irrigation and aquaculture applications. Sound Sound can be described as mechanical energy transmitted by pressure waves in a material medium. Thus, sound can ...

  • Algae Control Solution for Chilean Salmon Industry?

    Since February 2016, Salmon farms in Chile have been suffering from an intensive Harmful Algal Bloom (HAB) which is causing massive numbers of salmon deaths. Ultrasonic technology combined with algae detection could be the solution for an industry facing economic losses totaling millions. Currently the Dutch algae control company, LG Sonic, is discussing the implementation of ultrasonic ...

  • Creating a Sustainable Food Future: Interim Findings - A menu of solutions to sustainably feed more than 9 billion people by 2050

    The world’s agricultural system faces a great balancing act. To meet different human needs, by 2050 it must simultaneously produce far more food for a population expected to reach about 9.6 billion, provide economic opportunities for the hundreds of millions of rural poor who depend on agriculture for their livelihoods, and reduce environmental impacts, including ecosystem degradation and ...

  • Tools to improve water quality

    This post is part of a series on World Water Week, an annual event designed to draw attention to and discuss global water issues. Read more posts in this series. Agricultural production often comes at the expense of water quality. As my colleague, Mindy Selman, ...

  • Wetland Solutions for People and Nature

    Wetlands act as water sources, sinks and purifiers. They protect our shores. They are Earth’s greatest natural carbon stores. They support abundant and unique nature. But we have lost so much of our wetland treasure. And those that remain are under growing pressure. This makes people and nature vulnerable. It’s time to reverse the trend. ...

  • To build a sustainable world, academics need to tear down the Ivory Tower

    Avoiding societal collapse means building bridges between science and the rest of the world. Until recently, Earth was so big compared with humanity’s impacts that its resources seemed limitless. But that is no longer the case. Thanks to rapid growth in both human population and per capita consumption, we are now on the edge of irrevocable damage to our planetary life ...

  • 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 ...

  • Questions and answers on the Commission Communication `Towards a Circular Economy` and the Waste Targets Review

    What is a circular economy? A circular economy preserves the value added in products for as long as possible and virtually eliminates waste. It retains the resources within the economy when a product has reached the end of its life, so that they remain in productive use and create further value. It may involve: Increasing the time products deliver their service before ...

  • Ocean science for sustainable development: Facts and figures

    Sarah Grimes explores why we need good ocean monitoring, how to get it, and why it still fails Small Island Developing States. Oceans are a critically important component of the Earth system, supporting ecosystem and human health. They regulate the weather and climate; are essential for producing freshwater; and soak up ...

  • Taming taste and odor (T & O) problems in a water treatment plant

    Taming Taste & Odor (T&O) Problems Some taste and odors are caused by mineral constituents in the water, e.g. excess chlorine and hydrogen sulfide. However the majority of taste and odor are the result of biologic activity. Spring turnover of lakes and algal blooms are responsible for Blue-green algae (Cyanobacterium), Green algae and diatoms that introduce filter clogging organisms ...
