  • Ecological impacts of fluridone and copper sulphate in catfish aquaculture ponds

    Fluridone and copper sulphate are often used for controlling macrophytes and algae in aquaculture ponds. The present study examined the ecological effects of these chemicals on macrophyte, phytoplankton, and zooplankton biomass, plankton community structure, water quality parameters, and fish survival and yield in catfish culture ponds using a randomized complete block design. The estimated ...

  • Effects of different management regimes on mangrove ecosystem services in Java, Indonesia

    This new report, published by Wageningen University and Wetlands International, seeks to fill a significant gap in mangrove ecosystem service estimates. While several studies have sought to measure and value the ecosystem services provided by mangrove ecosystems in general, this new piece of research has for the first time conducted separate evaluations for zones that are characterised by ...

  • Portugal: P. Japonicus shrimp venture breeds profits

    An experimental venture into the P. Japonicus shrimp business has yielded good profits. The shrimp’s market prices are four times better than for P. vannamei , more common in Portugal. The owner believes water quality management is critical. He uses only AIRE-O2® aeration. He explained, 'This species digs into sand and only comes out at night to feed. At night, we need the best environment in the ...

  • Utilization of inland saline water for Spirulina cultivation

    An attempt was made to assess the suitability of the inland saline water of Rohtak (Haryana) for mass cultivation of Spirulina platensis, a salt loving cyanobacterium. Cultivation of S. platensis was performed in indoor and outdoor culture units. The investigation revealed that the yield of biomass in de-calcified inland saline water was comparable to the yield obtained in ...

  • Massive freshwater gains from producing food at sea

    Water scarcity may be the most limiting factor to increasing world food production. Irrigation water is already overdrawn beyond sustainable levels and to increase reliance on rainfed agriculture is risky, even more so with climate change. However, to promote deliberate food production at sea, both fished and farmed, and both plant and animal, requires no freshwater or land. The thousands of ...

  • 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, ...

  • Cultivating energy crop production

    A NEW Farm Bill is moving through the Congressional legislative process. Along the way, commercial agriculture is debating the energy impacts of future corn and soybean production. The growth of corn-based ethanol and soybean-based biodiesel has created competition for the feed inputs into animal agriculture, namely corn and soybeans. While most of agriculture discusses energy production from ...

  • Seasteading could be the answer to sustainably feeding 9 billion people

    Self-sufficient nation states in the middle of the ocean might be our ticket to a sustainable future. Oceans cover 71 percent of Earth’s surface, yet provide less than 2 percent of the food we eat. The growing demand for seafood, however — predicted to rise to 8 percent during the next decade — from an already depleted and exhausted ocean is forcing ...

  • Monitoring greenhouse gases from biofuel crops

    Global issues such as climate change and energy security have driven rapid growth in renewable energy production - wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR analysers to study the GHG emissions of biomass ...

  • Use of Aquaclean in freshwater shrimp production

    The increase in popularity of freshwater shrimp (Macrobrachium Rosenbergii) production has prompted researchers to develop better and more efficient production methods. The current production methods are sufficient to justify the growing of freshwater shrimp, however, to stay competitive long term in the market place, producers will have to increase yields and reduce costs. Current niche markets ...

  • 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 ...

  • The Role of Mangroves in Fisheries Enhancement

    In 2011 humans caught and consumed 78.9 million tonnes of fish, crustaceans, molluscs and other species groups from the world’s oceans, accounting for 16.6% of the world’s animal protein intake (FAO 2012). This is projected to increase further, to over 93 million tonnes by 2030 (World Bank 2013). Global demand for fish products has increased dramatically over recent decades. Fishing ...

  • Science’s role in growing diverse, nutritious food

    Can science meet the demand for more diverse and nutritious food? Jan Piotrowski investigates. The riots that swept Africa in 2007 and 2008 in response to the spiralling costs of staple crops brought the effects of food shortages into sharp focus. Images of unrest circled the globe, and the consequent instability brought to the forefront of political debate a question that had ...

  • The Global Food Challenge Explained in 18 Graphics

    The world is projected to hold a whopping 9.6 billion people by 2050. Figuring out how to feed all these people—while also advancing rural development, reducing greenhouse gas emissions, and protecting valuable ecosystems—is one of the greatest challenges of our era. So what’s causing the global food challenge, and how can the world solve it? We begin to answer these questions ...
